Between January and mid-October 2025, calls to local 211 helplines from people seeking food pantries in their community held steady at nearly 1,000 calls per day.

But as the government shutdown entered its fourth week in late October, states began to warn residents that Supplemental Nutrition Assistance Program benefits, sometimes known as food stamps, would likely be affected. Nearly 42 million Americans receive SNAP benefits each month.

Over the next several days, calls to 211 from people seeking food pantries doubled to over 2,200 per day. Then on Oct. 26, the Trump administration announced that SNAP benefits would not be arriving as scheduled in November. The next day, food pantry calls skyrocketed to 3,324. The following day, calls reached 3,870. By Wednesday, it was 4,214.

We are public health scientists specializing in health communication and unmet social needs. We and our colleagues have been working closely with the 211 network of helplines across the U.S. for 18 years.

Excluding disasters, sudden surges of this magnitude in requests for food or any other need are rare at 211s, and can signal both public worry and need, as happened in the first weeks of the COVID-19 pandemic.

What is 211?

Like 911 for emergencies, 211 is a national three-digit dialing code, launched in 2000, that connects callers to information specialists at the nearest local 211 helpline. Those specialists listen to callers’ needs and provide them with referrals to health and social service providers near them that may be able to help.

Every call to 211 is classified by the need of the caller, such as shelter, rent, utilities or food – each of which has its own code.

Callers are disproportionately women, most of whom have children or teens living in their homes. Most don’t make enough money to make ends meet. They call 211 seeking help paying rent or utility bills, getting food to feed their family, or securing household necessities like a winter coat for a child, or a mattress.

The hotline does not solve these problems for callers, but 211 information specialists use the most current local information available to refer callers to service agencies that are most likely to have resources to help.

The 211 network is the closest thing the U.S. has to a real-time surveillance system of the needs of low-income Americans.

There are roughly 200 state and local 211s in the U.S., and on an average day they will collectively field between 35,000 and 40,000 requests for help. Each request is coded using a taxonomy of over 10,000 need types, is time- and date-stamped, and is linked to the caller’s ZIP code. In addition to phone calls received by their helplines, 211s increasingly track requests they receive online, through their websites. The national network of 211s covers all 50 states and 99% of the U.S. population.

It’s encouraging to us that with each passing year of giving talks and lectures about 211, more and more audience members raise their hands when asked if they’ve ever heard of 211. But it’s far from 100%. If you are one of those with your hand down, here’s what you need to know.

Food banks around the country are having trouble keeping their shelves stocked.

Gaining local insights

Our team aims to deploy the latest methods from data science, predictive analytics and artificial intelligence to detect trends in critical needs sooner and at a more localized level, increasing the speed and efficiency of getting needed help to local community members.

Our research has described the needs of callers who reach out to 211, community capacity to respond to callers’ needs, the ability of 211 to detect rapid changes in community needs, and the benefits of integrating health referrals into 211s.

When we saw food requests rising sharply in late October, we reached out to local leaders at 211 call centers to get insights into what they were hearing from callers.

Robin Pokojski, vice president of 211 and community partnerships at United Way of Greater St. Louis, reported that with all the uncertainty around SNAP benefits, callers were initially “anticipating” a need for food pantries. Tiffany Olson, who directs essential services at Crisis Connections and its 211 call center in Washington state, shared that even callers who rely heavily on their SNAP benefits sometimes need to use food banks as a supplement.

Those callers know that pivoting to rely solely on food banks probably won’t be enough to meet their food needs in full. They realize that food pantries and food banks will be more heavily burdened if SNAP benefits are unavailable.

Increasing the impact of 211 data

The trove of daily data on the needs of U.S. callers to 211 at the ZIP code level is unparalleled. Yet for years it was virtually invisible to anyone who didn’t work at a 211 hotline.

Even for people who work and volunteer within the 211 system, formal reporting on caller needs within a community was minimal, such as a one-page annual summary.

That changed in 2013.

Working with 211s across the country, our team created 211 Counts, a collection of user-friendly, public-facing data dashboards for local 211s across the U.S.

The dashboards allow users to explore the top needs in their community, see which neighborhoods are affected most and understand how needs are changing over time. The data can be sorted by legislative districts, school districts and counties to make the findings more relevant to different audiences.

Data on 211 requests are updated each night. Now in its 12th year, 211 Counts includes data on over 90 million requests from 211 callers in all or parts of 44 states. The local dashboards have been visited millions of times.

211 as an early-warning system

This is not the first time data collected through 211 hotlines has detected early signs of trouble for some Americans. Just weeks ago, we found that calls from people seeking assistance making car payments have been increasing steadily for five months, with daily calls peaking in October, at nearly twice the rate of May 2025.

Before that, 211s were months ahead of news reporting in seeing public distress associated with the 2022 baby formula shortage, the 2016 Flint water crisis and the 2007 subprime mortgage crisis.

When requests for major needs like food increase three- to fourfold overnight, every local 211 is likely to register this abrupt change.

But when less frequent needs, such as car payment assistance, creep up slowly, with an extra call here and there over several months, it’s unlikely that any local 211 hotline would notice.

That’s when the advantages of big data are greatest. By combining caller needs from 211s across the country, patterns emerge that would otherwise be missed. New data science tools are rapidly improving the speed and accuracy of detecting slight changes. When community and national leaders are made aware of potential rising threats, those threats can be tracked more closely and responses prepared.

It’s easy to lose sight of the fact that each data point is a hungry child or a worried parent.

Hotlines and food banks and food pantries need support in this moment to feed people. But most local safety net systems struggle to meet their community’s needs all the time. Data that documents the magnitude of need won’t fix the scarcity of local assistance, but it can help guide communities in allocating limited resources.

De COP en COP, une géopolitique de la procrastination climatique

Source: The Conversation – France (in French) – By Moïse Tsayem, professeur en géographie, Le Mans Université

Entre promesses ajournées et coalitions aux intérêts divergents, les COP se suivent et démultiplient les arènes de négociation sans nécessairement réussir à accélérer l’action climatique. À l’aube de la COP30, organisée au Brésil, l’enjeu est de taille : sortir de la procrastination climatique. Les organisations de la société civile jouent un rôle crucial et bousculent de plus en plus les arènes onusiennes.


La trentième conférence des parties sur le climat (COP 30), présidée par le Brésil, a lieu à Belém, en Amazonie, en novembre 2025. Depuis 1995, ce rendez-vous annuel des États qui ont ratifié la Convention-Cadre des Nations unies sur les changements climatiques (CCNUCC) a produit seulement deux traités majeurs : le protocole de Kyoto et l’accord de Paris. Leur mise en œuvre, dont les effets positifs en termes de réduction des émissions de gaz à effet de serre tardent encore à pleinement se concrétiser, est révélatrice de la « procrastination » qui caractérise la gouvernance internationale de la lutte contre les changements climatiques.

Les engagements pris sont souvent recyclés d’une COP à l’autre et leur mise en œuvre est trop souvent repoussée aux calendes grecques. C’est par exemple le cas de l’engagement des pays développés, de financer à hauteur de 100 milliards de dollars par an, les pays en développement, dans le cadre du fonds vert pour le climat, créé lors de la COP 15 à Copenhague en 2009. Il a été recyclé lors des COP suivantes, sans pour autant être tenu. L’inertie s’explique par les intérêts divergents des États, regroupés au sein de coalitions hétérogènes.

Le monopole des États est toutefois bousculé par les organisations de la société civile (OSC). Que peuvent-elles pour l’action climatique ? Comment cette tension s’inscrit-elle dans le cadre de la COP30 à venir au Brésil ?

Une démultiplication des arènes officielles depuis 30 ans

Depuis la première COP en 1995, le paysage des négociations climatiques s’est complexifié : au format initial s’est ajoutée une deuxième arène avec l’entrée en vigueur du protocole de Kyoto (CMP) en 1997, puis une troisième avec l’accord de Paris (CMA) en 2015, chacune réunissant les États ayant ratifié ces accords.

Considéré comme un traité « expérimental », un « signal », ou une « impulsion » devant conduire à des engagements futurs plus ambitieux, le protocole de Kyoto n’a pas produit les résultats escomptés. Il reposait sur des engagements chiffrés de réduction des EGES des pays développés, avec des mécanismes de flexibilité, donc les échanges de quotas d’émissions. Mais en l’absence de ratification par les États-Unis, il n’a jamais pu être pleinement mis en application.

À quoi servent les COP ? Une brève histoire de la négociation climatique


En 2009, lors de la COP15, des négociations sont engagées pour un accord multilatéral de plus grande envergure pour l’après Kyoto. Celles-ci échouent du fait des tensions et des rivalités entre les États (confrontation entre l’Union européenne, les États-Unis et la Chine, marginalisation des pays en développement…).

L’accord de Paris, deuxième résultat majeur des COP, ouvre en 2015 une nouvelle approche. Les États, qu’ils soient développés ou en développement, doivent élaborer puis soumettre leurs Contributions nationales déterminées (CND). Autrement dit, des engagements et une feuille de route des actions qu’ils prévoient de mettre en œuvre pour lutter contre les changements climatiques à l’horizon 2030.

Chaque année depuis 2016, les COP, les CMP et les CMA ont lieu conjointement. Les CND ont fait l’objet d’un premier bilan en 2023. Il est prévu qu’elles soient examinées et rehaussées tous les 5 ans. Certains États en sont à la troisième version, pour des engagements à mettre en œuvre d’ici 2035.

Au fil du temps, le nombre d’arènes onusiennes relatives à la lutte contre le changement climatique s’est démultiplié, pour un succès tout relatif…

Bien qu’ayant été ratifié par davantage d’États que le protocole de Kyoto, l’accord de Paris souffre du même écueil : il est non contraignant. Quant aux engagements pris par les États dans le cadre des CND, ils aboutiraient, en l’état, à une hausse de la température moyenne de l’ordre de 3,5 °C à l’horizon 2100, largement au-dessus de l’objectif de 1,5 °C.

Comme le protocole de Kyoto avant lui, l’accord n’a pas pris en compte la complexité de la gouvernance du monde, avec l’influence économique grandissante exercée notamment par les multinationales et par les pays émergents (donc la Chine et l’Inde), qui refaçonnent les relations commerciales internationales. La question environnementale a été progressivement reléguée à l’arrière-plan : l’imaginaire d’un grand régulateur central apte à définir et à distribuer des droits d’émissions semble de moins en moins en prise avec la réalité. Tout cela s’inscrit en réalité dans la reconfiguration des rapports géopolitiques internationaux, avec la montée en puissance du Sud global, et la crise latente du multilatéralisme.

Dans le même temps, l’accord de Paris, tout comme le processus d’élaboration du texte des COP, tend à mettre les désaccords sous le tapis, puisque les décisions sont prises au consensus. Il en résulte des difficultés bien concrètes, notamment pour sortir des énergies fossiles.

Des coalitions d’États qui orientent les négociations

Au fil des ans, la COP s’est alourdie avec une multitude de coalitions d’États défendant des intérêts variés. Un clivage classique oppose généralement les pays développés aux pays en développement. Lors des dernières COP, l’ONU a recensé 14 coalitions d’États qui ont pris part aux négociations.

L’arène des COP : une hétérogénéité de groupes d’acteurs étatiques aux intérêts divergents.
Fourni par l’auteur

Beaucoup de ces coalitions sont constituées d’États du Sud (Afrique, Amérique du Sud, Asie) : groupe africain, Alliance bolivarienne des Amériques, Groupe des pays en développement partageant les mêmes idées, etc.). Pour faire entendre leurs positionnements ou leurs spécificités, et porter leur voix au sein des COP, les pays en développement ont multiplié les coalitions, parfois hétérogènes.

Plusieurs États sont ainsi membres de plusieurs coalitions à la fois, suivant leurs enjeux et intérêts par rapport aux changements climatiques et à leurs niveaux de développement économique et social. Par exemple, la Chine, l’Inde et le Brésil sont membres de quatre coalitions, les Comores sont membres de six coalitions, et le Soudan est membre de six coalitions.

Il existe ainsi plusieurs groupes attentifs à la question des financements climatiques en lien avec des sujets bien précis. Par exemple, les Petits États insulaires en développement, très attentifs à la problématique de la hausse du niveau de la mer, ou encore les pays de forêt tropicale humide, très attentifs à la lutte contre la déforestation.

On retrouve aussi des regroupements plus traditionnels, comme celui des pays les moins avancés

ou le G77+Chine. Le groupe parapluie (États-Unis, Australie, Canada, Nouvelle Zélande…) rassemble de son côté plusieurs États peu prompts à l’ambition climatique. Quelques États qui ont voulu se démarquer et garder une position neutre sont membres du groupe pour l’intégrité environnementale (Suisse, Corée du Sud, Mexique, etc.). L’Union européenne participe aux négociations en tant que groupe à part entière, même si chaque État membre participe parallèlement aux négociations en tant que Partie à la CNUCC.

Ces coalitions peuvent refléter les intérêts économiques des États vis-à-vis des énergies fossiles : le Groupe des États arabes, par exemple, réunit plusieurs membres de l’OPEP, qui ont davantage intérêt à maintenir le statu quo sur les énergies fossiles.

Les COP mises au défi par la société civile

Si les États sont au cœur des COP, ils ne sont pas pour autant les seuls acteurs. Les organisations de la société civile (OSC) ont pris une place considérable dans les négociations, soit aux côtés des États, soit en constituant leurs propres arènes, subsidiaires aux négociations officielles.

Ces OSC, très hétérogènes, sont organisées en groupes et réseaux d’une grande diversité. Des ONG peuvent ainsi être associées à des fondations humanitaires, à des think tanks, à des syndicats, à des églises, à des chercheurs, etc. C’est par exemple le cas de l’ONG 350.org, ou encore de l’ONG Climate Action Network.

Les OSC s’expriment non seulement à titre individuel, mais aussi à travers les réseaux qui les représentent ou les fédèrent, par exemple le Climate Action Network, ou le réseau Climate Justice Now. Certaines OSC et leurs réseaux organisent des off ou des side-events plus ou moins informels pour médiatiser et rendre visibles des sujets bien spécifiques ou des angles morts des négociations (la question des océans, celle des peuples autochtones, la compensation carbone, les énergies fossiles, etc.). Par exemple, l’ONG Climate Justice Alliance médiatise le renoncement aux énergies fossiles articulé, avec une transition énergétique juste portée par les communautés et les collectifs de citoyens, tandis que l’ONG Ocean Conservancy se positionne sur la question des océans. Quant à la Organización de los Pueblos Indígenas de la Amazonía, elle œuvre pour une meilleure prise en compte des peuples indigènes.

Hétérogénéité des organisations de la société civile constituant des arènes subsidiaires aux COP.

Depuis 2015, on assiste à une évolution majeure, caractérisée par une multiplication des fronts de mobilisation, avec un foisonnement des actions par le bas, sur le terrain, ce qui décentre le regard par rapport à l’arène onusienne. Pour ces OSC, celle-ci n’est plus le point névralgique de la lutte contre les changements climatiques.

Une nouvelle vague d’OSC (Just Stop Oil, Friday for future, Extinction Rebellion…) entend mettre la pression sur des décideurs, sur des entreprises, généralement des acteurs « clés », en politisant et en radicalisant le débat, parfois sur la base des rapports du GIEC, soulignant ainsi l’importance de la prise en compte des travaux scientifiques.

Grace aux OSC, la justice climatique est devenue un sujet majeur qui reconfigure la lutte contre les changements climatiques. Parallèlement à ces actions (grèves pour le climat, blocages et sit in, etc.), d’autres OSC, plus anciennes et/ou plus structurées, judiciarisent la lutte contre les changements climatiques en portant plainte contre des États. C’est ce qui s’est passé par exemple en France, avec l’Affaire du Siècle, procédure judiciaire inédite engagée en 2018 contre l’État français, accusé d’inaction climatique, par quatre ONG (Notre Affaire à Tous, la Fondation pour la Nature et l’Homme, Greenpeace France et Oxfam France).

Qu’attendre de la COP30 au Brésil ?

Cette reconfiguration devrait une fois de plus être à l’œuvre durant la COP30, d’autant plus que celle-ci revêt plusieurs symboles : ce sera la première COP en Amazonie, le 20e anniversaire de l’entrée en vigueur du protocole de Kyoto et le 10e anniversaire de l’accord de Paris. Elle a lieu dans le pays hôte de l’adoption de la CCNUCC, un des traités fondateurs du développement durable, institué en 1992 lors du sommet de Rio de Janeiro sur l’environnement et le développement.

Les lettres de cadrage diffusées par le président de cette COP, nommé par le président du Brésil, donnent le ton. Comme pour les précédentes COP, le financement de l’action climatique des États en développement sera un enjeu majeur. Ces États, dans la dynamique géopolitique du Sud global, avec les pays émergents en tête desquels le Brésil, souligneront la nécessité d’alimenter et d’augmenter les fonds dédiés à leur participation à la lutte contre les changements climatiques, dans le respect des principes de la justice climatique.

Souhaitant que cette COP 30 soit la « COP amazonienne », le Brésil envisage que l’importance accordée aux forêts tropicales soit renforcée, avec une augmentation des financements et des investissements pour réduire la déforestation et la dégradation des forêts.

Le Brésil espère que cette COP soit celle du déclic – ou du tournant – pour la mise en œuvre des actions ambitieuses, innovantes et incluses. Le mutirão, c’est-à-dire l’effort collectif, dans un esprit de coopération associant toutes les parties prenantes (États, organisations internationales, collectivités locales, OSC, peuples indigènes, entreprises, citoyens, etc.), est prôné pour rehausser et réactiver l’action climatique dans une perspective globale.

Combien de temps une tique peut-elle vivre sans piquer un humain ?

Source: The Conversation – France in French (2) – By Claudio Lazzari, Professeur des Universités, Département de biologie animale et de génétique, Université de Tours

La tique est un acarien parasite bien connu pour se nourrir de sang (on dit qu’elle est hématophage) et pour transmettre des maladies, telles que la maladie de Lyme. Contrairement à une idée reçue, les tiques ne dépendent pas de l’être humain : elles piquent principalement des animaux sauvages et domestiques. La question devient alors : combien de temps peuvent-elles survivre sans se nourrir ?


Les scientifiques ont identifié environ 900 espèces de tiques, dont une quarantaine est présente en France. La durée d’existence d’une tique et les particularités de son cycle de vie varient beaucoup d’une espèce à l’autre.

La piqûre de la tique

Contrairement aux moustiques ou aux punaises qui mènent une vie libre et ne cherchent un hôte que lorsqu’ils ont besoin de sang, les tiques s’accrochent fermement à leur hôte pendant de longues périodes, parfois de plusieurs mois, durant lesquelles elles se nourrissent lentement et de façon continue.

L’attachement d’une tique à la peau d’un animal ou d’un humain est très ferme grâce à ses pièces buccales munies de crochets et à la sécrétion d’une substance qui la colle à la peau. De cette façon, la bouche de la tique reste en contact permanent avec une petite accumulation interne de sang produit par l’action de sa salive qui détruit des tissus et des vaisseaux capillaires de l’intérieur de la peau, ce qui lui assure un apport de nourriture permanent.

Un besoin de sang à chaque étape de sa vie

Une tique passe par quatre stades de développement :

  • œuf,
  • larve (6 pattes),
  • nymphe (8 pattes),
  • adulte.

Chaque étape, de la larve à l’adulte, nécessite du sang pour se développer et pour passer au stade suivant de même que pour survivre et se reproduire. Il s’agit d’organismes dits « hématophages obligés », car le sang des animaux constitue leur unique source de nutriments tout au long de leur vie.

Une fois qu’elle est prête à passer au stade suivant, ou lorsque la femelle a accumulé suffisamment d’œufs, la tique se détache pour muer ou pondre dans le sol. Ce cycle peut nécessiter, selon les espèces, un, deux ou trois hôtes différents que la tique parasitera au cours de sa vie.

La quantité d’œufs qu’une tique femelle peut produire avant de se détacher de l’hôte est énorme, grâce à son corps souple qui augmente de taille à mesure que les œufs s’accumulent par milliers à l’intérieur. Une petite tique à peine repérable devient ainsi une boule d’œufs et de sang de plus d’un ou deux centimètres lorsqu’elle est prête à pondre.

Certaines espèces montent à l’état de larve sur un hôte et ne le quittent qu’une fois adultes, au bout de quelques mois, au moment de la ponte des œufs et le cycle se répète de manière continue.

D’autres espèces passent leur première année de vie en tant que larve sur un rongeur, leur seconde année en tant que nymphe sur un herbivore de taille moyenne, comme un lapin, puis leur troisième année en tant qu’adulte sur une vache, pendant laquelle la femelle produit une quantité colossale d’œufs qu’elle laisse par terre avant de mourir.

Une question de santé humaine et animale

En France, la maladie de Lyme est principalement transmise par la tique dure Ixodes ricinus, qui est largement répandue sur le territoire hexagonal, à l’exception du pourtour méditerranéen et des régions en altitude. La même espèce peut transmettre d’autres maladies, comme l’encéphalite à tiques.

D’autres espèces de tiques aussi présentes en France transmettent également des maladies qui affectent l’homme, comme la fièvre boutonneuse méditerranéenne et le Tibola, qui sont causées par des bactéries du genre Rickettsia et transmises par des tiques comme Rhipicephalus sanguineus ou Dermacentor.

Les tiques impactent également la santé animale, car elles transmettent des micro-organismes pathogènes au bétail, comme les responsables de la piroplasmose et de l’anaplasmose bovine, provoquant des pertes économiques importantes dans les élevages et dans la production laitière.

La survie sans piquer

Les tiques ont la capacité remarquable de survivre longtemps sans se nourrir. Pour supporter le manque de nourriture, elles mettent en place diverses stratégies, comme ralentir leur métabolisme et ainsi leurs dépenses énergétiques, ou consommer leurs propres tissus, un processus appelé « autophagie ».

Selon plusieurs études scientifiques, à l’état de nymphe ou d’adulte, les tiques peuvent survivre plus d’un an sans se nourrir dans la litière (l’ensemble de feuilles mortes et débris végétaux en décomposition qui recouvrent le sol), si les conditions environnementales sont favorables, notamment une température basse et une humidité élevée. Comme tout organisme de taille relativement petite, les tiques sont particulièrement exposées à la perte d’eau corporelle par dessiccation. Elles possèdent néanmoins des mécanismes pour absorber de l’eau de l’air si l’humidité relative de l’environnement le permet, comme au moment de la rosée.

Le jeûne hors hôte se caractérise par un métabolisme lent avec de longs intervalles d’inactivité, ponctués par des déplacements courts afin d’augmenter l’absorption d’eau ou de rechercher une position permettant de détecter un hôte. Si la température et l’humidité relative restent adéquates, la survie dépend alors du maintien d’un équilibre délicat entre une utilisation judicieuse de l’énergie et le maintien de la teneur en eau du corps, car l’équilibre hydrique est probablement le facteur le plus critique.

Pour maximiser les possibilités de trouver un hôte, les tiques ont un comportement assez particulier, consistant à grimper sur une brindille à côté des corridors de passage d’animaux et restent longtemps accrochées avec les pattes étendues. Ce comportement, appelé « de quête », leur permet de détecter le passage d’un hôte et de monter sur lui.

Il est important de rappeler que les tiques ne préfèrent pas les humains comme hôtes. Elles s’attaquent naturellement aux mammifères sauvages (cerfs, rongeurs), aux oiseaux et aux animaux domestiques. Elles ne dépendent donc pas de l’homme pour survivre ou évoluer. Une tique peut très bien vivre toute sa vie sans jamais piquer un être humain, pourvu qu’elle trouve un autre hôte.

Who gets SNAP benefits to buy groceries and what the government pays for the program – in 5 charts

Source: The Conversation – USA (2) – By Tracy Roof, Associate Professor of Political Science, University of Richmond

Some 42 million Americans rely on SNAP benefits to put food on the table. Robert Nickelsberg/Getty Images News

The Supplemental Nutrition Assistance Program has helped low-income Americans buy groceries for decades with few disruptions.

But on Nov. 1, 2025, the federal government halted the flow of funds to states to distribute as SNAP benefits. The Trump administration blames this unprecedented disruption on the federal government shutdown, which began a month earlier. Following multiple court orders, federal officials said they plan to distribute at least a portion of the US$8 billion that’s supposed to flow monthly to the states to cover the costs of the program’s benefits. On Nov. 6, another judge ordered the distribution of all SNAP funds that were due in November.

Although the program costs billions, the benefits that families and individuals can receive from it are modest. The most a person living on their own can get is $298 a month, but many people receive far less. The average benefit is an estimated $6.17 daily – which falls below some estimates of the minimum cost of eating a nutritious diet in the United States.

The Conversation U.S. asked Tracy Roof, a political scientist who has researched the history of government nutrition programs, to explain who SNAP helps, how enrollment varies from state to state and what the program costs to run.

How many Americans are enrolled in SNAP?

The number of people getting SNAP benefits soared during the Great Recession, a big downturn that began in December 2007 and had long-lasting effects on the economy.

Because of high unemployment and poverty rates, more people were eligible for SNAP during those years. Many states, eager to bring dollars into their economies from federally funded SNAP benefits, made unprecedented efforts to enroll eligible families. SNAP enrollment peaked in 2013 at roughly 15% of Americans. The number of the program’s participants fell as the economy recovered, but never returned to pre-recession levels because a greater share of eligible families continued to enroll in the program after the economic crisis than before.

When the COVID-19 pandemic upended the U.S. economy in 2020, the number of people with SNAP benefits soared again. President Donald Trump has blamed high enrollment in SNAP on the Biden administration “haphazardly” handing benefits “to anyone for the asking.”

That assertion is misleading. While the Biden White House increased benefits, it did not expand who was eligible for SNAP. In fact, President Joe Biden agreed to apply work requirements and time limits to more SNAP recipients. Moreover, states, not the federal government, are primarily responsible for determining eligibility and enrolling people in SNAP. The number of people who received SNAP benefits during Biden’s presidency never exceeded 43 million – the peak reached in September 2020 during the first Trump administration.

The number of people using SNAP benefits to buy groceries has not fallen substantially because the number of people in poverty and the cost of living, including what Americans pay for food, have both increased since 2020.

How much does the program cost the federal government?

In inflation-adjusted 2024 dollars, spending peaked at $128 billion in 2021 and fell to $100 billion in 2024 – nearing pre-pandemic levels.

The program’s spending had previously increased significantly during the Great Recession because SNAP enrollment rose and benefits were temporarily increased. Spending declined as the economy gradually recovered.

While the number of people on SNAP during the pandemic and its aftermath never reached the peak of the Great Recession, the level of spending did reach much higher levels. This was because of three steps taken to increase benefits by more sizable amounts than during the Great Recession.

  1. The Families First Act, which Trump signed into law in March 2020, offered “emergency allotments” that increased monthly benefits for many households receiving SNAP. Biden extended emergency benefits to all households enrolled in the program in April 2021, driving spending even higher. Budget legislation that Congress passed in December 2022 ended the emergency benefits in February 2023.

  2. Biden signed two pieces of legislation in 2021 that temporarily increased the maximum SNAP benefit by 15% through September 2021 – the height of the pandemic’s effects on the economy.

  3. The Biden administration adjusted the basis for calculating monthly benefits in October 2021, just as the temporary increase was expiring. That change permanently increased benefits.

Most households getting SNAP benefits include children and older people

Nearly 60% of Americans enrolled in SNAP are either children under 18 or adults who are 60 or older.

About 1 in 5 non-elderly adults with SNAP benefits have a disability.

Less than 10% of all the people receiving SNAP benefits are able-bodied adults without children who are between the ages of 19 and 49.

Around 55% of all families with children that receive SNAP benefits include at least one employed adult.

Enrollment ranges widely from state to state

In some states, 1 in 5 people receive SNAP benefits. In others, it’s 1 in 20.

The share of a state’s population getting SNAP is determined both by its poverty rate and its policies. Those policies can affect who is eligible and the share of eligible families and individuals who enroll in the program.

Of the 10 states with the highest percentage of people on SNAP, five are also in the top 10 for the percentage of the population in poverty: New Mexico, Louisiana, Oklahoma, West Virginia and Nevada.

According to 2022 data, nine of those 10 states have enrolled nearly all families who are eligible for SNAP benefits: New Mexico, Louisiana, Oregon, Oklahoma, West Virginia, Massachusetts, Nevada, Pennsylvania and Illinois.

States vary widely in terms of the percentage of eligible families who obtain SNAP benefits. In the bottom quarter of states, fewer than 81% of eligible residents in 2022 were getting benefits. The percentage in Arkansas was the lowest: 59%.

States with the highest enrollment numbers tend to make it easier for their residents to get SNAP benefits by minimizing red tape and engaging in more outreach to eligible families. They also adopt policies that allow some people to qualify for SNAP at higher incomes or with more assets.

Americans of all races and ethnic backgrounds rely on SNAP

A little over 35% of people who get SNAP benefits are white, more than any other racial or ethnic group. Around 26% are Black and 16% are Hispanic.

Although more white people are enrolled in SNAP, Census data shows that greater percentages of Black and Hispanic people get these benefits: 24.4% of Black people and 17.2% of Hispanic people compared with 9.7% of white people. This is because these groups are disproportionately poor.

Undocumented immigrants are not eligible for SNAP. Only 4.4% of SNAP recipients in the 2023 fiscal year were immigrants who were not citizens but legally present in the U.S., such as refugees.

The “big” tax-and-spending package Trump signed into law on July 4, 2025, however, ended SNAP eligibility for most of those immigrants.

Pennsylvania counties face tough choices on spending $2B opioid settlement funds

In communities across Pennsylvania, local officials are deciding how to spend over US$2 billion dollars from the state’s opioid settlement agreements.

For many, the task is proving promising yet challenging – and raises questions about how to best navigate complex local needs.

Pennsylvania will receive the money over 18 years from lawsuits filed by state attorneys general against opioid manufacturers and distributors. About 70% of these funds will be distributed to county governments, with the remaining funds going to the state legislature and the groups that leveraged the lawsuits.

The amount provided to each county is proportional to the opioid-related harms experienced by the county. Each county government is responsible for developing its own funding strategy for substance use programs, which can focus on things such as prevention, treatment, recovery or harm reduction.

Our research team at Penn State interviewed 72 county officials, health professionals and service providers across six counties in Pennsylvania to understand their early experiences with these funds.

We summarized our findings in a recent article for the peer-reviewed Substance Abuse Treatment, Prevention, and Policy journal. We found that stakeholders view the settlement funds not simply as extra money but as an opportunity to heal – and to test how well local communities can make their own choices about spending.

‘Bags of money’ but limited guidance

Pennsylvania’s distribution strategy was designed to give local governments flexibility. A document called Exhibit E lists the ways that counties can spend the settlement money.

This collaborative document was written as part of the settlement to outline shared guidelines that apply to all the states receiving funds. It lists everything from the types of approved substance use treatments to what qualifies as prevention. In practice, Exhibit E provides diverse opportunities for spending but has also created widespread uncertainty among recipients about which strategies to prioritize.

Some interviewees felt overwhelmed by the logistics of their funding decisions. They understood that the general purpose of the money is to support communities harmed by opioid overprescription. But they lacked clarity on how much time they had to spend it, what the reporting requirements are, and what counts as an eligible activity. For example, some wanted to use the funds to pay administrators for new prevention programs, but administration isn’t included in Exhibit E.

As one local elected official in southeastern Pennsylvania put it, “There’s been a whole lot of stuff that we don’t know – more than we do know. And now we’re running with bags of money through the community and (we’re) not sure how we can spend it, or if we can spend it.”

Many county officials worried about spending the funds too slowly, or on activities that could end up being ineligible or ineffective. Service providers sometimes didn’t know who in their county had the authority to decide where the money went. While they may have wanted to provide recommendations or input, they were unsure how.

A chance to experiment and innovate

Even amid confusion, most of the people we interviewed saw the settlement funding as a unique opportunity.

Exhibit E’s broad guidelines allow for experimentation, and many expressed interest in supporting local needs and implementing projects that they had wanted for a long time. This included things like expanding peer recovery support programs or establishing family support services.

“The guidelines are so varied that it gives those local communities opportunities to look at the menu and find out from community members, ‘How can we help resolve this problem together?’” one local drug and alcohol department employee told us. “It’s a collaborative that really helps the community as a whole get well as a whole. I am a real believer in ‘It takes a village.’”

Several participants emphasized that the flexibility in Exhibit E creates room to revise plans as needs evolve or change. Counties can change their funding priorities each year to adapt.

Several counties have already started issuing small grants to grassroots organizations, recognizing that those closest to people harmed by the opioid crisis often know best what kinds of interventions might work.

One county employee involved in distributing funds in her county shared that her team was “willing to try anything, really, within the bounds.”

“And if it doesn’t work, we can back off,” she added. “But I feel like you don’t know until you try it.”

A moral responsibility to get it right

Although our study focused on policy implementation, participants often framed their responsibilities in moral terms.

Many said they felt a strong obligation to use the funds wisely, given the scale of loss their communities have endured. The Pennsylvania Department of Health reported 4,719 overdose deaths in the state in 2023, and 83% were opioid-related. That number dropped to 3,336 in 2024, mirroring national trends.

One elected official described the funds as “the only hope we can provide families that have lost loved ones to this crisis,” emphasizing that he felt a “real obligation” to make the funds count.

Others echoed that careful, transparent decision-making is part of a broader recovery effort. Beyond abiding by funding guidelines, they felt it was also important to be honest and transparent to community members.

“We don’t want to come out with ‘Pennsylvania wasted its money, or (this) county wasted its money,’” said an addictions researcher.

Still others cautioned that the settlement funds alone cannot repair the full scope of harms caused by the opioid crisis, warning against viewing the settlements as a cure-all.

“There’s not really a monetary value that you can put on these things,” a person who works in the substance use sector told us. “I’m glad that this money’s available, but ultimately for me … it’s a little too late. You know? All my friends are already dead.”

Always watching: How ICE’s plan to monitor social media 24/7 threatens privacy and civic participation

Source: The Conversation – USA – By Nicole M. Bennett, Ph.D. Candidate in Geography and Assistant Director at the Center for Refugee Studies, Indiana University

ICE’s surveillance gaze is likely to sweep across millions of people’s social media posts. Westend61/Westend61 via Getty Images

When most people think about immigration enforcement, they picture border crossings and airport checkpoints. But the new front line may be your social media feed.

U.S. Immigration and Customs Enforcement has published a request for information for private-sector contractors to launch a round-the-clock social media monitoring program. The request states that private contractors will be paid to comb through “Facebook, Google+, LinkedIn, Pinterest, Tumblr, Instagram, VK, Flickr, Myspace, X (formerly Twitter), TikTok, Reddit, WhatsApp, YouTube, etc.,” turning public posts into enforcement leads that feed directly into ICE’s databases.

The request for information reads like something out of a cyber thriller: dozens of analysts working in shifts, strict deadlines measured in minutes, a tiered system of prioritizing high-risk individuals, and the latest software keeping constant watch.

I am a researcher who studies the intersection of data governance, digital technologies and the U.S. federal government. I believe that the ICE request for information also signals a concerning if logical next step in a longer trend, one that moves the U.S. border from the physical world into the digital.

A new structure of surveillance

ICE already searches social media using a service called SocialNet that monitors most major online platforms. The agency has also contracted with Zignal Labs for its AI-powered social media monitoring system.

The Customs and Border Protection agency also searches social media posts on the devices of some travelers at ports of entry, and the U.S. State Department reviews social media posts when foreigners seek visas to enter the United States.

ICE and other federal law enforcement agencies already search social media.

What would change isn’t only the scale of monitoring but its structure. Instead of government agents gathering evidence case by case, ICE is building a public-private surveillance loop that transforms everyday online activity into potential evidence.

Private contractors would be tasked with scraping publicly available data to collecting messages, including posts and other media and data. The contractors would be able to correlate those findings with data in commercial datasets from brokers such as LexisNexis Accurint and Thomson Reuters CLEAR along with government-owned databases. Analysts would be required to produce dossiers for ICE field offices within tight deadlines – sometimes just 30 minutes for a high-priority case.

Those files don’t exist in isolation. They feed directly into Palantir Technologies’ Investigative Case Management system, the digital backbone of modern immigration enforcement. There, this social media data would join a growing web of license plate scans, utility records, property data and biometrics, creating what is effectively a searchable portrait of a person’s life.

Who gets caught in the net?

Officially, ICE says its data collection would focus on people who are already linked to ongoing cases or potential threats. In practice, the net is far wider.

The danger here is that when one person is flagged, their friends, relatives, fellow organizers or any of their acquaintances can also become subjects of scrutiny. Previous contracts for facial recognition tools and location tracking have shown how easily these systems expand beyond their original scope. What starts as enforcement can turn into surveillance of entire communities.

What ICE says and what history shows

ICE frames the project as modernization: a way to identify a target’s location by identifying aliases and detecting patterns that traditional methods might miss. Planning documents say contractors cannot create fake profiles and must store all analysis on ICE servers.

But history suggests these kinds of guardrails often fail. Investigations have revealed how informal data-sharing between local police and federal agents allowed ICE to access systems it wasn’t authorized to use. The agency has repeatedly purchased massive datasets from brokers to sidestep warrant requirements. And despite a White House freeze on spyware procurement, ICE quietly revived a contract with Paragon’s Graphite tool, software reportedly capable of infiltrating encrypted apps such as WhatsApp and Signal.

Meanwhile, ICE’s vendor ecosystem keeps expanding: Clearview AI for face matching, ShadowDragon’s SocialNet for mapping networks, Babel Street’s location history service Locate X, and LexisNexis for looking up people. ICE is also purchasing tools from surveillance firm PenLink that combine location data with social media data. Together, these platforms make continuous, automated monitoring not only possible but routine.

ICE is purchasing an AI tool that correlates people’s locations with their social media posts.

Lessons from abroad

The United States isn’t alone in government monitoring of social media. In the United Kingdom, a new police unit tasked with scanning online discussions about immigration and civil unrest has drawn criticism for blurring the line between public safety and political policing.

Across the globe, spyware scandals have shown how lawful access tools that were initially justified for counterterrorism were later used against journalists and activists. Once these systems exist, mission creep, also known as function creep, becomes the rule rather than the exception.

The social cost of being watched

Around-the-clock surveillance doesn’t just gather information – it also changes behavior.

Research found that visits to Wikipedia articles on terrorism dropped sharply immediately after revelations about the National Security Agency’s global surveillance in June 2013.

For immigrants and activists, the stakes are higher. A post about a protest or a joke can be reinterpreted as “intelligence.” Knowing that federal contractors may be watching in real time encourages self-censorship and discourages civic participation. In this environment, the digital self, an identity composed of biometric markers, algorithmic classifications, risk scores and digital traces, becomes a risk that follows you across platforms and databases.

What’s new and why it matters now

What is genuinely new is the privatization of interpretation. ICE isn’t just collecting more data, it is outsourcing judgment to private contractors. Private analysts, aided by artificial intelligence, are likely to decide what online behavior signals danger and what doesn’t. That decision-making happens rapidly and across large numbers of people, for the most part beyond public oversight.

At the same time, the consolidation of data means social media content can now sit beside location and biometric information inside Palantir’s hub. Enforcement increasingly happens through data correlations, raising questions about due process.

ICE’s request for information is likely to evolve into a full procurement contract within months, and recent litigation from the League of Women Voters and the Electronic Privacy Information Center against the Department of Homeland Security suggests that the oversight is likely to lag far behind the technology. ICE’s plan to maintain permanent watch floors, open indoor spaces equipped with video and computer monitors, that are staffed 24 hours a day, 365 days a year signals that this likely isn’t a temporary experiment and instead is a new operational norm.

What accountability looks like

Transparency starts with public disclosure of the algorithms and scoring systems ICE uses. Advocacy groups such as the American Civil Liberties Union argue that law enforcement agencies should meet the same warrant standards online that they do in physical spaces. The Brennan Center for Justice and the ACLU argue that there should be independent oversight of surveillance systems for accuracy and bias. And several U.S. senators have introduced legislation to limit bulk purchases from data brokers.

Without checks like these, I believe that the boundary between border control and everyday life is likely to keep dissolving. As the digital border expands, it risks ensnaring anyone whose online presence becomes legible to the system.

House speaker’s refusal to seat Arizona representative is supported by history and law

Source: The Conversation – USA – By Jennifer Selin, Associate Professor of Law, Arizona State University

Adelita Grijalva won a special election in Arizona on Sept. 23, 2025, becoming the newest member of Congress and the state’s first Latina representative.

Yet, despite the Arizona secretary of state’s formal certification of Grijalva, a Democrat, as the winner of that election, Rep.-elect Grijalva has not been sworn into office.

Republican House Speaker Mike Johnson, who by law is responsible for making that happen, claims the government shutdown means Grijalva must wait until the federal government resumes normal operations.

In response, Arizona Attorney General Kris Mayes filed a lawsuit on Oct. 21 alleging that Johnson has denied the state its representation in Congress.

No one disputes that Grijalva is the next member of the House of Representatives for the 7th District of Arizona. And the House hasn’t conducted business since Sept. 19, when Johnson gaveled it out of session.

So why does it matter whether Grijalva is sworn in now or later?

The lawsuit filed by Mayes claims Johnson is using his power to “strengthen his hand” in the ongoing budget battle that has shut down the federal government. Additionally, Grijalva has pledged to provide the last necessary signature to force a vote on a bipartisan measure demanding that the Trump administration release government files on convicted sex offender Jeffrey Epstein.

But as a law scholar who analyzes government institutions, I recognize that the speaker historically has had power to determine when the oath is administered. And courts have been reluctant to weigh in the speaker’s use of that power.

The speaker’s historical power

The framers of the Constitution were divided on whether to require members of Congress to take an oath of office. Representing a political compromise on the issue, the Constitution requires all Senate and House members to take an oath to support the Constitution before assuming office. But the framers left the substance and administration of the oath up to Congress.

Congress put the speaker of the House in charge of administering the oath to incoming House members and first specified its text in 1789. The Oath Act required members of Congress to “solemnly swear or affirm” support of the Constitution.

Historically, the speaker administered the oath to new House members state by state. This meant that each state’s newly elected representatives stood alone in front of Congress. However, in 1929, House Speaker Nicolas Longworth changed tradition so that all new members were sworn in at the same time.

Longworth did so after Oscar DePriest – the first African American to serve in Congress in the 20th century – won an election in Illinois to replace Rep. Martin B. Madden, who had died of a heart attack. Longworth acted in response to speculation that Southern Democrats would attempt to prevent a Black lawmaker from joining the House. Rather than swearing in members state by state, Longworth swore in all members at once so DePriest was not stopped from taking the oath of office.

Since that time, the speaker has administered the oath of office to all newly elected members of the House as a collective unit.

How things work now

Under current law, the speaker must administer the oath of office to all House members prior to them taking their seats.

Here’s how this has worked over the past few decades:

After the House elects a speaker, the member with the longest continuous service in the House – called the dean of the House – administers the oath to the speaker. Then the speaker administers the oath to the rest of the members all together as a mark of a new Congress.

The idea is that despite partisan differences, every legislator commits in front of the others to uphold the Constitution.

But occasionally, either because of illness, a special election or other circumstances, a newly elected member of Congress can’t take the oath with everyone else. When that happens, that person is sworn in at a later date.

On Sept. 9, 2025, for example, Democrat James Walkinshaw won a special election to succeed the late Gerry Connolly, who died in office while representing Virginia’s 11th congressional district. Johnson swore Walkinshaw in the next day.

While the speaker has the responsibility for administering the oath, the House may adopt a resolution to designate a judge or House member selected by the speaker to do the job for him.

In 1999, for example, Speaker Dennis Hastert designated retired California Judge Ellen Sickles James to administer the oath to Rep.-elect George Miller.

Regardless of who swears into office a member of Congress who could not attend the collective ceremony, the administration of the oath has traditionally occurred on days in which the House is session. But it does not have to be that way.

The law is ambiguous on when the oath is administered.

And House speakers have not always acted swiftly. In spring 2021, for instance, Speaker of the House Nancy Pelosi waited 25 days before administering the oath to Republican Rep.-elect Julia Letlow. That’s because the House did not have a session scheduled immediately following Letlow’s election.

Johnson has referred to this particular delay as the “Pelosi precedent,” setting a standard practice of the speaker waiting to administer the oath until Congress is in session.

Why does it matter?

The delay in administering Grijalva the oath is the longest in modern history.

While Grijalva waits, she does not have access to the resources typically provided to members of the House to help them perform their jobs, including an operating budget for her offices or even the ability to log in to key databases.

This means Grijalva is limited in her ability to represent her over 800,000 constituents.

She describes her current situation as “having the title but none of the job.”

Grijalva, Arizona Attorney General Mayes and congressional Democrats accuse the speaker of playing politics. But history and the law suggest that may be Johnson’s prerogative until the government reopens.

Overwhelm the public with muzzle-velocity headlines: A strategy rooted in racism and authoritarianism

Source: The Conversation – USA – By Angie Chuang, Associate Professor of Journalism, University of Colorado Boulder

The seemingly unending barrage of stressful news is a strategy with ties to the past. zimmytws/iStock via Getty Images

The headlines documenting President Donald Trump’s plan to send federal troops to San Francisco followed a familiar arc. “Trump claims ‘unquestioned power’ in vow to send troops to San Francisco,” The Guardian reported on Oct. 20, 2025. The next day, the San Francisco Chronicle blared: “S.F. threatens to sue if Trump brings in National Guard.” Then, on Oct. 23, “Trump reverses his decision to send troops to San Francisco,” as ABC News put it, after Trump posted that conversations with the city’s mayor and tech moguls had swayed him.

It was another example of how Trump’s shifting policy positions, racially inflammatory statements and threats frequently fuel a flurry of headlines, reflecting what some psychologists are calling “media saturation overload” or “Trump stress disorder.”

This barrage of information may seem like overcommunication from a hyperactive administration. But it is much more than that.

Scholars have found that the constant, often conflicting and at times false information coming out of the White House and shared via social media posts and the conventional news media causes members of the public to see truth and fact as relative and makes them more likely to dismiss those who disagree with them as untruthful. This leaves doubt about what’s real and what isn’t.

This citizen paralysis creates what philosopher Hannah Arendt described in “The Origins of Totalitarianism” as a general public “for whom the distinction between fact and fiction … no longer exist.” When lies are truth and truth is derided as lies, Arendt wrote, ordinary people lose their bearings and can be manipulated for totalitarian objectives.

Meanwhile, many journalists have openly acknowledged fatigue with the pace and nature of the Trump administrations’ news cycles, amid frequent newsroom layoffs, mergers and closures.

I am a longtime journalist and now scholar of journalism and race, trained to see the methods and aims behind political leaders’ press operations. And as I show in my forthcoming book, the Trump administration’s rhetorical strategies echo the playbooks of authoritarian and white supremacist organizations such as the Third Reich and some factions of the modern alt-right movement. They are intended to narrow the scope of who belongs as an American.

Headlines at ‘muzzle velocity’

The Trump administration’s rhetorical strategies include claiming victim status while often laying blame on immigrants or other scapegoats in ways that I believe betray racist intent. At the same time it has overwhelmed journalists and the public with breaking news.

This strategy was laid out by Steve Bannon, an influential Trump supporter and strategist in his first administration, during a 2019 PBS “Frontline” interview, when he described the media as “the opposition party.”

“They’re dumb and they’re lazy, they can only focus on one thing at a time,” he said. “All we have to do is flood the zone. … Bang, bang, bang. These guys will never – will never be able to recover. But we’ve got to start with muzzle velocity.”

Steve Bannon outlined the strategy of overwhelming people with announcements at what he termed muzzle velocity in a 2019 interview with “Frontline.”

Bannon has long been associated with the alt-right, a movement known for rhetorical tactics that minimize and obfuscate its true aims.

A strategy forged in Trump’s first term

As I detail in my book, “American Otherness in Journalism: News Media Representations of Identity and Belonging,” Trump and his key advisers have been developing, refining and ramping up their news media manipulation for a long time.

An early example of this is the way the administration used these tactics through Trump’s public responses to the fatal violence at the August 2017 Unite the Right protest in Charlottesville, Virginia.

The two-day rally was organized by a white nationalist blogger and attended by members of neo-Nazi, white supremacist and far-right militias protesting the removal of a statue of Confederate Gen. Robert E. Lee from a Charlottesville park. They marched with tiki torches, flew Confederate and Nazi flags and chanted antisemitic and racist slogans.

Amid violent clashes with counterprotesters on the second day, a neo-Nazi sympathizer drove into a crowd, killing a 32-year-old woman and injuring many others.

My study of television news coverage of Unite the Right found that the majority of news reports focused on the contradictory and inflammatory statements that Trump made about the antisemitic and racist protesters. Trump’s Aug. 15, 2017, press conference remark about blame on both sides after what happened garnered the most news media attention: “I think there is blame on both sides,” he said. “You had some very bad people in that group. You also had some very fine people on both sides.”

Exploiting chaos

The uncertainty surrounding what he meant created a cycle of news stories implying and denying that he sympathizes with white supremacists.

This is-he-or-isn’t-he intrigue spurred a surge of what fits the description of Bannon’s “muzzle-velocity” news headlines: “Trump declares ‘racism is evil’ amid pressure over Charlottesville” followed closely by “Trump defends White-nationalist protesters” and “Why Trump can’t get his story straight on Charlottesville.”

With the focus on Trump’s comments and what he might have really meant, the news media ultimately missed covering at the time the long-term threat posed by these white supremacist and other extremist groups.

Echoing a playbook from the past

Scholars have identified the fascist roots of these “post-truth” strategies: strongmen leaders uninterested in establishing leadership through honesty and transparency.

A recent scholarly analysis of Trump’s leadership concludes that the second-term president is overwhelming the public into “organized despair” by pitting races against each other while targeting minority groups as scapegoats, a tactic that hearkens back to 1930s Germany.

A 2019 analysis of Trump’s narrative style describes how he presents himself as a “strongman” fighting invisible forces of censorship and suppression. It also points out that this was part of the appeal of fascist leaders such as Mussolini and Hitler.

Researchers of Nazi propaganda identified key tactics in the German press such as name-calling and lumping together groups seen as opposition – communists, liberals and Jews – until public understanding of those groups blur into phrases like “enemies of Germany.” The messaging was constant and immersive, carried in local and national newspapers, radio, film and posters.

A key part of Trump’s rhetorical strategy is using race without directly referring to it. For example, Trump has described cities with large nonwhite populations such as Washington, D.C., and Chicago as “out of control” or “dirty,” contrary to actual crime statistics. He’s also questioned Kamala Harris’ racial identity, suggesting she “happened to turn Black.” And referring to Black football players who had been protesting systemic racism by kneeling during the national anthem, Trump said, “Get that son of a bitch off the field right now,” which many observers interpreted as racist because he was insulting people of color for the act of protesting racism.

This racial coding has been used by white supremacist groups to mask their true intent. They also use less overt labels such as “alt-right” or “pro-white” as a “rhetorical bridge” to the mainstream public.

In the case of the NFL protesters, the plausible deniability became an actual denial. Trump perfected this move when, during a 2020 debate with Joe Biden, he said, “Proud Boys – stand back and stand by,” referencing another group accused of thinly veiled racism.

Drowning in headlines

I believe that the endgame for this strategy is authoritarian power that greatly narrows the scope of who truly belongs and has rights in this country as an American.

This media saturation – drowning the public with a thousand Trump-generated headlines – allows his administration to keep dominating and controlling national attention.

But the media-consuming public can use the tools they have to encourage news outlets to better inform the public by identifying the media saturation strategy and reporting on why leaders are using it.

Otherwise, if news consumers let the headline overload do what it’s intended to do, and become overwhelmed and paralyzed, they become pawns in what I consider a ploy to make America less egalitarian and less democratic.

Seashells from centuries ago show that seagrass meadows on Florida’s Nature Coast are thriving

Source: The Conversation – USA (2) – By Michal Kowalewski, Thompson Chair of Invertebrate Paleontology, University of Florida

Seagrass meadows are an essential part of Florida’s coastal ecosystem. Jenny Adler

During a day at the beach, it’s common to see people walking up and down the shore collecting seashells.

As a paleontologist and marine ecologist, we look at shells a bit differently than the average beachcomber. Most people dig up shells in the sand and see beautiful color patterns or unusual shapes. But we tend to focus on how old these shells are and what they tell us about the habitat they come from.

You may be surprised to learn that the translucent spiral shell you plucked from the sand belonged to a snail that lived long before Columbus sailed to the New World. And that unassuming clamshell you might nonchalantly toss away belonged to a mollusk that filtered seawater when pharaohs ruled Egypt.

In recent decades, scientists have used methods such as radiocarbon dating to assess the age of shells, along with bones and other skeletal remains, scattered around Earth’s surface.

Increasingly, paleontologists and conservation biologists like us are turning to these remains as potential treasure troves of information about what various habitats were like before humans entered the picture. The insights we glean from this approach, known as conservation paleobiology, can result in more effective conservation, restoration and management strategies aimed at the protection or recovery of many essential habitats.

This approach has proved, among other things, that cows reshaped shellfish communities on the California shelf, caribou used the same calving grounds for millennia, and Caribbean sharks were much more diverse in the past.

Over the past decade, we have applied conservation paleobiology to Florida’s Nature Coast, home to an extensive and intricate patchwork of seagrass meadows and sand. Prior to our studies, scientists’ understanding of those meadows was largely uninformed by historical data.

Why seagrass matters

It may not be obvious at first glance why we should be interested in the past history of seagrass meadows.

But these meadows are among the most important structural habitats on our planet. Myriad species, including sea turtles and manatees, forage, shelter or reproduce in those habitats, making seagrasses major hot spots of biodiversity.

Beyond these benefits, seagrasses offer extremely valuable services. They oxygenate ocean waters, draw down carbon dioxide and stabilize bottom sediments. And critically for Florida’s coastline, seagrass can dampen wave energy, which helps to protect shorelines and coastal communities from the punishing effects of tropical storms and hurricanes.

By providing all these services, seagrasses fuel a tremendous economic engine that generates global revenue in excess of US$6 trillion annually, according to an analysis published in the journal Nature Reviews Biodiversity in February 2025.

Unfortunately, seagrass meadows are in decline globally, vanishing rapidly due to broad-scale environmental changes and an onslaught of local human impacts. Efforts are underway all over the world to protect seagrasses that still exist and restore those that have been lost.

Shells in Florida’s seagrass meadows

The challenge inherent to our research is that seagrasses don’t have a hard skeleton, so they are very rarely found in the fossil record.

Fortunately, we found that the shells of mollusks that prefer to dwell in seagrass are a reliable proxy for the grass itself. In general, the quality of ecological data provided by fossil shellfish is outstanding.

When living and dead organisms are alike, we can infer that local ecosystems have not changed notably despite human activities. Conversely, when live and dead mollusk species differ, it usually is a sign that a habitat has been heavily altered by humans.

Location, location, location

In our initial study, our team examined about a 40-mile (65-kilometer) swath of nearshore habitats in an area just north of the Suwannee River.

We found that seagrass meadows often span only a few acres, forming a regional patchwork of vegetated and open-sand habitats. We also observed that distinct sets of mollusk species inhabit meadows and open sands today. This was not surprising, as many previous studies have shown that different mollusks live in seagrass and open-sand habitats.

Next, we looked at the shells of dead mollusks found in surface sediments in the area. Using radiocarbon dating, we showed that about half of these shells belonged to mollusks that lived prior to the Industrial Revolution. Many shells dated back to previous millennia.

If these small patches of seagrass meadows were waxing, waning or shifting location over the recent centuries, then we would expect each spot on the seafloor to harbor a mix of dead shells representing species from both habitats. However, we found that the species of dead mollusks in seagrass patches were remarkably similar to those that live there now. The same was the case for the mollusks from open sands.

This suggests that this mosaic of seagrass patches and open-sand bottoms has been remarkably stable for hundreds of years. We do not know why the seagrass consistently thrived for centuries in specific spots within a seemingly uniform environment. But whatever the reason, this habitat is not a mosaic of meadows in constant flux, but rather, a seascape that has remained the same for a long time.

This is an important find for conservation efforts. It means that it may be unwise to assume that we can compensate for seagrass losses by simply planting new meadows in open-sand habitats.

Broadening the scope

In our newest study, we broadened our scope to compare living mollusks and dead mollusks across multiple estuaries along the Nature Coast, a 93-mile (150-kilometer) stretch of Florida’s Gulf Coast.

As with our first study, this broader study revealed many remarkable similarities between the mollusks that live there now and the mollusks from previous centuries and millennia, documented by shells.

We found that the mollusks that are common today and those that were common in the past represent virtually the same suite of species, and their relative abundance stayed steady, too.

Even more remarkably, both the live mollusks and shells from previous centuries document the same changes in dominant mollusk species between the southern and northern regions of the study area.

Today, mollusks are not the same everywhere along the Nature Coast. This reflects the fact that coastal waters are increasingly nutritious in the north. Consequently, seagrass is taller and denser moving north, and the suites of mollusk species that live in them change as well.

The shells of dead mollusks tell the same story. This indicates that not much has changed along this stretch of the Gulf Coast since preindustrial times.

Highlighting what’s working

Knowing that seagrass meadows in this area have maintained their ecological character and integrity for centuries or longer is a powerful argument for their continued protection.

Understandably, most conservation paleobiology studies have focused on threatened species, degraded habitats or imperiled systems, such as reef sharks, oyster beds or freshwater mussels. As a result, these studies generally document population collapse, biodiversity loss, habitat shrinking and overall ecosystem decline.

But we believe it is equally important for investigators in our field to study systems that are believed to be stable and resilient. In this case, the unspoiled status of the Nature Coast seagrass meadows makes them a much-needed benchmark to assess the state of other seagrass systems that have been altered by human activities. This can offer insights into which conservation efforts are working and how best to restore and maintain similar habitats elsewhere.

AI could worsen inequalities in schools – teachers are key to whether it will

Today’s teachers find themselves thrust into a difficult position with generative AI. New tools are coming online at a blistering pace and being adopted just as quickly, whether they’re personalized tutors and study buddies for students or lesson plan generators and assignment graders for teachers. Schools are traditionally slow to adapt to change, which makes such rapid-fire developments especially destabilizing.

The uncertainties accompanying the artificial intelligence onslaught come amid existing challenges the teaching profession has faced for years. Teachers have been working with increasingly scarce resources – and even scarcer time – while facing mounting expectations not only for their students’ academic performance, but also their social-emotional development. Many teachers are burned out, and they’re leaving the profession in record numbers.

All of this matters because teacher quality is the single most important factor in school influencing student achievement. And the impact of teachers is greatest for students who are most disadvantaged. How teachers end up using, or not using, AI to support their teaching – and their students’ learning – may be the most crucial determinant of whether AI’s use in schools narrows or widens existing equity gaps.

We have been conducting research on how public school teachers feel about generative AI technologies.

The initial results, which are currently under review, reveal deep ambivalence about AI’s growing role in K-12 education. Our work also shows how inadequate training and unclear communications could worsen existing inequalities among schools.

A ‘thought partner’ for busy teachers

As part of a larger project examining AI integration in education, we interviewed 22 teachers in a large public school district in the United States that has been an early and enthusiastic adopter of AI. The district serves a multilingual and socioeconomically diverse student population, with over 160 languages spoken and approximately three-quarters of students eligible for free or reduced-price lunch.

The teachers who participated in our study spanned elementary, middle school and high school grade levels, and represented a variety of subject areas, including science, technology, engineering and mathematics, social studies, special education, and culturally and linguistically diverse education. We asked these teachers to describe how they first encountered generative AI tools, how they currently use them, and the broader shifts they have observed in their schools. Teachers also reflected on both the opportunities and challenges of using AI tools in their classrooms.

Mirroring a recent survey finding that AI has helped teachers save up to six hours per week of work, the teachers in our study pointed to AI’s ability to create more space in the day for themselves and their students. Turning to AI for help writing lesson plans and assessments not only saves time, but it also gives teachers a tool for brainstorming ideas, helping them feel less isolated in their work. One high school teacher with over 11 years’ experience reflected:

“The most significant benefit that AI has brought to my life as a teacher is having work-life balance. It has decreased my stress 80-fold because I am able to have a thought partner. Teachers are really isolated, even though we work with people constantly … When I’m exhausted, it gives me support and help with ideas.”

Why lack of training matters

However, not all teachers felt well-equipped to benefit from AI. Much of what they told us boiled down to a lack of resources and other professional support. An elementary school classroom teacher explained:

“It’s just a lack of time. We don’t really get much planning time, and it would be a new tool to learn, so we would have to take the time personally to learn how to use it and where to find everything.”

Many teachers underscored the need for – and current lack of – professional development offerings to help them understand and integrate AI into their teaching.

Research on previous waves of technological innovations shows that under-resourced schools serving disadvantaged students are typically the least well-equipped to provide teachers with the professional support they need to make the most of new technologies.

Because well-resourced schools are far more likely to offer such support, the introduction of new technologies in schools tends to reinforce existing inequities in the education system.

When it comes to AI, well-resourced schools are best positioned to give teachers time, support and encouragement to “tinker” with AI and discover how and whether it can support their teaching and learning goals.

‘You need a relationship’ to learn

Our research also uncovered the importance of preserving the relational nature of teaching and learning, even – or perhaps especially – in the age of AI. As one middle school social studies teacher observed:

“A machine can give you information, but most students we know are not able to get information from something that’s just printed out for them and put it into their heads. You need a relationship. Some kids can do online school or read a book and teach themselves, but that’s like 2%. Most kids need a social environment to do it.”

Here again, prior research shows us that teachers in well-resourced schools are better equipped to introduce new technologies in ways that augment rather than undermine the relational dimensions of teaching and learning. And again, teachers are crucial in determining how and whether AI, like all new technologies, is used to support their teaching and student learning.

That’s why we believe the practices established during this current period of rapid AI development and adoption will profoundly influence whether educational inequities are dismantled or deepened.

Grounded in the classroom

Going forward, we see the need for research to examine how generative AI is changing teachers’ practice and relationship to their work. Their input can inform practices that empower teachers as professionals and advance student learning.

This approach requires adequate institutional support at the school and district levels. It also means listening to the real experiences of teachers and students instead of responding to the promised benefits touted by education technologies companies.
