Avant le pétrole vénézuelien, il y a eu les bananes du Guatemala…

Dans les années 1950 déjà, les États-Unis intervenaient contre un gouvernement démocratiquement élu au nom d’une menace idéologique, tout en protégeant des intérêts économiques majeurs. Mais si les ressorts se ressemblent, les méthodes et le degré de transparence ont profondément changé.


Dans la foulée de la frappe militaire américaine qui a conduit à l’arrestation du président vénézuélien Nicolás Maduro le 3 janvier 2026, l’administration Trump a surtout affiché son ambition d’obtenir un accès sans entrave au pétrole du Venezuela, reléguant au second plan des objectifs plus classiques de politique étrangère comme la lutte contre le trafic de drogue ou le soutien à la démocratie et à la stabilité régionale.

Lors de sa première conférence de presse après l’opération, le président Donald Trump a ainsi affirmé que les compagnies pétrolières avaint un rôle important à jouer et que les revenus du pétrole contribueraient à financer toute nouvelle intervention au Venezuela.

Peu après, les animateurs de « Fox & Friends » ont interpelé Trump sur ces prévisions :

« Nous avons les plus grandes compagnies pétrolières du monde », a répondu Trump, « les plus importantes, les meilleures, et nous allons y être très fortement impliqués ».

En tant qu’historien des relations entre les États-Unis et l’Amérique latine, je ne suis pas surpris de voir le pétrole, ou toute autre ressource, jouer un rôle dans la politique américaine à l’égard de la région. Ce qui m’a en revanche frappé, c’est la franchise avec laquelle l’administration Trump reconnaît le rôle déterminant du pétrole dans sa politique envers le Venezuela.

Comme je l’ai détaillé dans mon livre paru en 2026, Caribbean Blood Pacts: Guatemala and the Cold War Struggle for Freedom (NDT : livre non traduit en français), les interventions militaires américaines en Amérique latine ont, pour l’essentiel, été menées de manière clandestine. Et lorsque les États-Unis ont orchestré le coup d’État qui a renversé le président démocratiquement élu du Guatemala en 1954, ils ont dissimulé le rôle qu’avaient joué les considérations économiques dans cette opération.

Un « poulpe » puissant

Au début des années 1950, le Guatemala était devenu l’une des principaux fournisseurs de bananes pour les Américains, comme c’est d’ailleurs toujours le cas aujourd’hui.

La United Fruit Company possédait alors plus de 220 000 hectares de terres guatémaltèques, en grande partie grâce aux accords conclus avec les dictatures précédentes. Ces propriétés reposaient sur le travail intensif d’ouvriers agricoles pauvres, souvent chassés de leurs terres traditionnelles. Leur rémunération était rarement stable, et ils subissaient régulièrement des licenciements et des baisses de salaire.

Basée à Boston, cette multinationale a tissé des liens avec des dictateurs et des responsables locaux en Amérique centrale, dans de nombreuses îles des Caraïbes et dans certaines régions d’Amérique du Sud afin d’acquérir d’immenses domaines destinés aux chemins de fer et aux plantations de bananes.

Les populations locales la surnommaient le « pulpo » – « poulpe » en espagnol – car l’entreprise semblait intervenir dans la structuration de la vie politique, de l’économie et de la vie quotidienne de la région. En Colombie, le gouvernement a par exemple brutalement réprimé une grève des travailleurs de la United Fruit en 1928, faisant des centaines de morts. Cet épisode sanglant de l’histoire colombienne a d’ailleurs servi de base factuelle à une intrigue secondaire de « Cent ans de solitude », le roman épique de Gabriel García Márquez, lauréat du prix Nobel de littérature en 1982.

L’influence apparemment sans limites de l’entreprise dans les pays où elle opérait a nourri le stéréotype des nations d’Amérique centrale comme des « républiques bananières ».

United Fruit possédait notamment la marque de bananes Chiquita, qu’elle a largement promue, y compris à travers cette publicité produite dans les années 1940.

La révolution démocratique guatémaltèque

Au Guatemala, pays historiquement marqué par des inégalités extrêmes, une vaste coalition s’est formée en 1944 pour renverser la dictature répressive lors d’un soulèvement populaire. Inspirée par les idéaux antifascistes de la Seconde Guerre mondiale, cette coalition ambitionnait de démocratiser le pays et de rendre son économie plus équitable.

Après des décennies de répression, les nouveaux dirigeants ont offert à de nombreux Guatémaltèques leur premier contact avec la démocratie. Sous la présidence de Juan José Arévalo, élu démocratiquement et en fonction de 1945 à 1951, le gouvernement a mis en place de nouvelles protections sociales ainsi qu’un code du travail légalisant la création et l’adhésion à des syndicats, et instaurant la journée de travail de huit heures.

En 1951, lui a succédé Jacobo Árbenz, lui aussi président démocratiquement élu.

Sous Árbenz, le Guatemala a mis en œuvre en 1952 un vaste programme de réforme agraire, attribuant des parcelles non exploitées aux ouvriers agricoles sans terre. Le gouvernement guatémaltèque affirmait que ces politiques permettraient de bâtir une société plus équitable pour la majorité indigène et pauvre du pays.

United Fruit a dénoncé ces réformes comme le produit d’une conspiration mondiale. L’entreprise affirmait que la majorité des syndicats du pays étaient contrôlés par des communistes mexicains et soviétiques, et présentait la réforme agraire comme une manœuvre visant à détruire le capitalisme.

Pression sur le Congrès pour une intervention

Au Guatemala, United Fruit a cherché à rallier le gouvernement américain à son combat contre les politiques menées par Árbenz. Si ses dirigeants se plaignaient bien du fait que les réformes guatémaltèques nuisaient à ses investissements financiers et alourdissaient ses coûts de main-d’œuvre, ils présentaient aussi toute entrave à leurs activités comme faisant partie d’un vaste complot communiste.

L’entreprise a mené l’offensive à travers une campagne publicitaire aux États-Unis et en exploitant la paranoïa anticommuniste dominante de l’époque.

Dès 1945, les dirigeants de la United Fruit Company ont commencé à rencontrer des responsables de l’administration Truman. Malgré le soutien d’ambassadeurs favorables à leur cause, le gouvernement américain ne semblait pas disposé à intervenir directement dans les affaires guatémaltèques. L’entreprise s’est alors tournée vers le Congrès, recrutant les lobbyistes Thomas Corcoran et Robert La Follette Jr., ancien sénateur, pour leurs réseaux politiques.

Dès le départ, Corcoran et La Follette ont fait pression auprès des républicains comme des démocrates, dans les deux chambres du Congrès, contre les politiques guatémaltèques – non pas en les présentant comme une menace pour les intérêts commerciaux de United Fruit, mais comme les éléments d’un complot communiste visant à détruire le capitalisme et les États-Unis.

Les efforts de la compagnie bananière ont porté leurs fruits en février 1949, lorsque plusieurs membres du Congrès ont dénoncé les réformes du droit du travail au Guatemala comme étant d’inspiration communiste. Le sénateur Claude Pepper a qualifié le code du travail de texte « manifestement et intentionnellement discriminatoire à l’égard de cette entreprise américaine » et d’« une mitrailleuse pointée sur la tête » de la United Fruit Company.

Deux jours plus tard, le membre de la Chambre des représentants John McCormack a repris mot pour mot cette déclaration, utilisant exactement les mêmes termes pour dénoncer les réformes. Les sénateurs Henry Cabot Lodge Jr., Lister Hill et le représentant Mike Mansfield ont eux aussi pris position publiquement, en reprenant les éléments de langage figurant dans les notes internes de la United Fruit.

Aucun élu n’a prononcé un mot sur les bananes.

Lobbying et campagnes de propagande

Ce travail de lobbying, nourri par la rhétorique anticommuniste, a culminé cinq ans plus tard, lorsque le gouvernement américain a orchestré un coup d’État qui a renversé Árbenz lors d’une opération clandestine.

L’opération a débuté en 1953, lorsque l’administration Eisenhower a autorisé la CIA à lancer une campagne de guerre psychologique destinée à manipuler l’armée guatémaltèque afin de renverser le gouvernement démocratiquement élu. Des agents de la CIA ont alors soudoyé des membres de l’armée guatémaltèque tandis que des émissions de radio anticommunistes étaient diffusées et un discours, porté par les religieux et dénonçant un prétendu projet communiste visant à détruire l’Église catholique du pays, se propageait dans tout le Guatemala.

Parallèlement, les États-Unis ont armé des organisations antigouvernementales à l’intérieur du Guatemala et dans les pays voisins afin de saper davantage encore le moral du gouvernement Árbenz. La United Fruit a également fait appel au pionnier des relations publiques Edward Bernays pour diffuser sa propagande, non pas au Guatemala mais aux États-Unis. Bernays fournissait aux journalistes américains des rapports et des textes présentant le pays d’Amérique centrale comme une marionnette de l’Union soviétique.

Ces documents, dont un film intitulé « Why the Kremlin Hates Bananas », ont circulé grâce à des médias complaisants et à des membres du Congrès complices.

La volonté de la United Fruit de renverser le gouvernement démocratiquement élu du Guatemala a été renforcée par ce film de propagande anticommuniste.

Détruire la révolution

En définitive – et les archives le démontrent –, l’action de la CIA a conduit des officiers de l’armée à renverser les dirigeants élus et à installer un régime plus favorable aux États-Unis, dirigé par Carlos Castillo Armas. Des Guatémaltèques opposés aux réformes ont massacré des responsables syndicaux, des responsables politiques et d’autres soutiens d’Árbenz et Arévalo. Selon des rapports officiels, au moins quarante-huit personnes sont mortes dans l’immédiat après-coup, tandis que des récits locaux font état de centaines de morts supplémentaires.

Pendant des décennies, le Guatemala s’est retrouvé aux mains de régimes militaires. De dictateur en dictateur, le pouvoir a réprimé brutalement toute opposition et instauré un climat de peur. Ces conditions ont contribué à des vagues d’émigration, comprenant d’innombrables réfugiés, mais aussi certains membres de gangs transnationaux.

Le retour de bâton

Afin d’étayer l’idée selon laquelle ce qui s’était produit au Guatemala n’avait rien à voir avec les bananes — conformément au discours de propagande de l’entreprise — l’administration Eisenhower a autorisé une procédure antitrust contre United Fruit, procédure qui avait été temporairement suspendue pendant l’opération afin de ne pas attirer davantage l’attention sur la société.

Ce fut le premier revers d’une longue série qui allait conduire au démantèlement de la United Fruit Company au milieu des années 1980. Après une succession de fusions, d’acquisitions et de scissions, ne demeure finalement que l’omniprésent logo de Miss Chiquita, apposé sur les bananes vendues par l’entreprise.

Et, selon de nombreux spécialistes des relations internationales, le Guatemala ne s’est jamais remis de la destruction de son expérience démocratique, brisée sous la pression des intérêts privés.

America’s new food pyramid – what’s changed and why?

Source: The Conversation – UK – By Cathal O’Hara, Postdoctoral Research Fellow, School of Population Health, RCSI University of Medicine and Health Sciences

The US has unveiled a controversial new food pyramid that’s causing a stir among nutrition experts. It represents the latest Dietary Guidelines for Americans – advice on what types and quantities of food and drink make up a healthy diet.

But the Trump administration’s new guidelines differ in many ways from previous versions. Most striking is the moralising language about “real” food and a stark shift of responsibility onto individuals, with all consideration of health equity stripped away.

The change from the previous plate graphic to an inverted pyramid looks revolutionary at first glance. But dig deeper and the actual dietary advice hasn’t changed as much as the presentation suggests.

The new website is eye-catching, with dramatic language about “restoring common sense”. Yet many recommendations mirror the 2020–25 guidelines that came before.

Eating a variety of fruit and vegetables, aiming for five a day, limiting saturated fat to less than 10% of energy – these are all still there. So are being mindful of portion sizes, reducing processed foods, limiting refined sugars and prioritising whole foods.

Where things get contentious is the emphasis on animal fats and protein. Meats, full-fat dairy, butter and beef tallow – all sources of saturated fat – are now recommended as healthy fats.

This contradicts established science. Saturated fats are known to increase heart disease and stroke risk, which is a leading cause of death in the US.

Doesn’t add up

Crucially, the guidelines don’t explain how people can eat these foods while keeping saturated fat below 10% of energy intake. The maths simply doesn’t add up.

Protein recommendations have doubled from 0.8g of protein per kilogram of body weight per day to 1.2–1.6g per kilogram of body weight per day. This follows social trends in protein popularity rather than nutritional need.

Adequate protein is important for muscle mass, blood sugar management and keeping hunger at bay. But this shift seems odd given that Americans are not under-consuming protein in the first place.

Many other contradictions are present too. The guidelines suggest flavouring meat and vegetables with salt while simultaneously restricting sodium – a component of salt.

Fibre and fibre-containing foods like pulses and legumes get barely a mention. There’s heavy emphasis on reducing highly processed foods, but no clear definition of what these include.

The alcohol advice is equally confusing. People are told to reduce intake without any guidance on how much is too much.

Perhaps most problematic is that the inverted pyramid image doesn’t match what’s written in the guidelines. Wholegrains sit at the narrow bottom, suggesting low consumption is recommended, but the text says two to four servings per day.

Meats and saturated fat sit at the top, implying high consumption is advised. As the pyramid is the primary visual tool for communicating these guidelines to the public, this confusion is deeply concerning.

The new US food pyramid.
The new US food pyramid.
HHS and USDA

It’s not just the content that’s changed – the entire process has been overhauled. The US government rejected the scientific report from independent experts that usually informs the guidelines. Instead, it hired a new group of scientists who chose not to consider any fields other than nutrition science.

International and US trends in dietary guidelines increasingly take a broader view, considering environmental impact, and whether people from all backgrounds can access, afford and prepare recommended foods.

This broader perspective acknowledges a harsh reality. In their current form, dietary guidelines have limited effect on what people actually eat.

A recent review of studies from 18 countries found that only 14% to 45% of people follow some or all of their country’s dietary recommendations.

The World Health Organization and many scientists have called for “food systems-based” dietary guidelines to address this. A food systems approach doesn’t just tell people what to eat. It recommends changes across all aspects of the food system – from production through to processing, distribution, preparation and consumption.

The new US guidelines, with their narrow focus and lack of clarity, will be difficult to implement. In any region where there’s an oversupply of high-calorie, low-nutrient foods and an undersupply of high-nutrient foods – such as fruit and vegetables – these guidelines are unlikely to influence what people actually eat.

What’s truly concerning is that these guidelines inform US government-funded food and nutrition programmes. That includes school meals, military and veteran meals, and other child and adult nutrition programmes. Through confusing and contradictory advice, the new guidelines have the potential to impede rather than promote the health of millions.

Other countries often take into account international practices when preparing their own dietary guidelines. However, it seems unlikely that they will follow this new direction from the US due to the confusing messaging, the inclusion of some questionable recommendations, and a lack of consideration of the broad range of factors that influence what people eat and drink.

Trying Veganuary might be challenging. Here’s some tips on keeping going

Source: The Conversation – UK – By Bethany Clark, PhD researcher in human geography, Aberystwyth University

Josep Suria/Shutterstock

In January some people start the year by trying to eat fewer animal products. Veganuary, as the campaign is called, began in 2014 and now attracts 25.8 million people worldwide.

One reason for trying Veganuary is a growing interest in acting in ways that reduce one’s environmental impact. And one of the key ways to do this at an individual level is to reduce the amount of meat consumed in one’s diet.

Various bodies, such as the Intergovermental Panel on Climate Change and the UK’s National Food Strategy, have cited large-scale meat reduction as a way to help address the climate emergency.

As its name suggests Veganuary is framed as a short-term challenge, by the campaign itself and other supporting organisations, such as The Vegetarian Society, with messaging focused not on what is being lost, but on new and exciting foods to cook at a time of year when people often try something new.

But for many participants changing long-established behaviour is hard. Changing eating habits is particularly difficult. Barriers to dietary change include ingrained habits and routines, social norms and conventions that allow people to justify existing behaviour. Research also suggests that the perception that reducing meat will be difficult can itself discourage people from attempting to do so.

There are, however, ways to make behaviour change easier. Drawing on research from the former government-based Behavioural Insights Team’s model of behaviour change, it’s possible to find ways to make it easier when changing dietary habits. They suggest four clear principles: easy, attractive, social and timely.

Chef Gordon Ramsay talks through some Veganuary specials.

Tips to make it easier

This year, Veganuary’s focus is encouraging a gradual approach that can reduce psychological barriers. Our personal attitudes and values tend to have a stronger influence on behaviour than external motivations such as financial incentives. To support lasting change, meat reduction can be aligned with values people already hold, making it easier to act in line with them. For example, exploring the climate footprint of a bag of mince and comparing with an alternative, enabling the chance to choose a less carbon-heavy alternative. Here are some tips on what can help to make Veganuary work for you.

1. Make it attractive

January often marks a return to routines after the festive period, and this can make the long, dark winter days feel monotonous. Novelty plays an important role here: it can boost creativity and increase happiness. Trying a new dietary pattern introduces new recipes and ingredients, offering an opportunity to experiment in the kitchen. Exploring new ways of eating may also encourage greater variety in meals, such as eating a wider range of vegetables and exploring new protein sources.

2. Make it social

Social eating is an important part of many people’s lives. Sharing a meat-free meal with family or friends can strengthen social bonds through a shared experience and increase feelings of camaraderie. Veganuary does not have to create divisions between meat eaters and vegans. Talking about the challenge as a group can encourage deeper discussion about the role of meat in our diets, while support from others can also help.

3. Make it timely

Breaking large goals into smaller ones can make them more achievable and more sustainable. Taking part in this dietary change over a clearly defined period allows participants to know there is an end in sight. Research on temporary challenges such as Veganuary and Dry January (giving up alcohol) suggests that habits formed during these periods can continue even after the challenge has ended.

Behaviour does not exist in a vacuum. It is shaped by what is considered normal in society, the physical environment as well as what is available in supermarkets, and broader political and economic systems.

When attempting to change behaviour – whether through a New Year’s resolution or a short-term dietary challenge – it is important to recognise this. Systems are often in place to maintain the status quo. Doing what works for you, without aiming for perfection, can make change feel more achievable. Slipping up does not mean failure: even one meat-free meal contributes to making a difference.

Will Google be third time lucky with new, AI-powered smart glasses?

Source: The Conversation – UK – By Max L Wilson, Associate Professor of Human-Computer Interaction, University of Nottingham

Tete Escape

It has been over a decade since Google Glass smart glasses were announced in 2013, followed by their swift withdrawal – in part because of low adoption. Their subsequent (and lesser known) second iteration was released in 2017 and aimed at the workplace. They were withdrawn in 2023.

In December 2025, Google made a new promise for smart glasses – with two new products to be released in 2026. But why have Google smart glasses struggled where others are succeeding? And will Google see success the third time around?

What is clear from developments in wearable tech over the last decade, is that
successful products are being built into things that people already like to wear:
watches, rings, bracelets and glasses.

These are the types of accessories that have emerged over centuries and currently adopted as normal in society.

Some of the most recent academic research is taking this approach, building
sensors into jewellery that people would actually want to wear. Research has developed a scale to measure the social acceptability of wearable technology (the WEAR scale, or Wearable Acceptability Range), which includes questions like: “I think my peers would find this device acceptable to wear.”

Noreen Kelly, from Iowa State University, and colleagues showed that at its core, this scale measured two things: that the device helped people reach a goal (that made it worth wearing), and that it did not create social anxiety about privacy and being seen as rude.

This latter issue was highlighted most prominently by the term that emerged for
Google Glass users: Glassholes. Although many studies have considered the potential benefits of smart glasses, from mental health to use in surgery, privacy concerns and other issues are ongoing for newer smart glasses.

All that said, “look-and-feel” keeps coming up the most common concern for potential buyers. The most successful products have been designed to be desirable as accessories first, and with smart technologies second. Typically, in fact, by designer brands.

A fine spectacle

After Google Glass, Snapchat released smart glasses called “spectacles”, which had cameras built in, focused on fashion and were more easily accepted into society. The now most prominent smart glasses were released by Meta (Facebook’s parent company), in collaboration with designer brands like Ray-Ban and Oakley. Most of these products include front facing cameras and conversational voice agent
support from Meta AI.

So what do we expect to see from Google Smart Glasses in 2026? Google has promised two products: one that is audio only, and one that has “screens” shown on the lenses (like Google Glass).

The biggest assumption (based on the promo videos) is that these will see a significant change in form factor, from the futuristic if not scary and unfamiliar design of Google Glass, to something that is more normally seen as glasses.

Google’s announcement also focused on the addition of AI (in fact, they announced
them as “AI Glasses” rather than smart glasses). The two types of product (audio
only AI Glasses, and AI Glasses with projections in the field of view), however, are not especially novel, even when combined with AI.

Meta’s Ray-Ban products are available in both modes, and include voice interaction with their own AI. These have been more successful than the recent Humane AI Pin, for example, which included front-facing cameras, other sensors, and voice support from an AI agent. This was the closest thing we’ve had so far to the Star Trek lapel communicators.

Direction of travel

Chances are, the main directions of innovation in this are, first, reducing the
chonkyness of smart glasses, which have necessarily been bulky to include
electronics and still look like that are normally proportioned.

“Building glasses you’ll want to wear” is how Google phrases it, and so we may see innovation from the company that just improves the aesthetic of smart glasses. They are also working with popular brand partners. Google also advertised the release of wired XR (Mixed Reality) glasses, which are significantly reduced in form factor compared to Virtual Reality headsets on the market.

Second, we could expect more integration with other Google products and services, where Google has many more commonly used products than Meta including Google Search, Google Maps, and GMail. Their promotional material shows examples of seeing Google Maps information in view in the AI Glasses, while walking through the streets.

Finally, and perhaps the biggest area of opportunity, is to innovate on the inclusion of additional sensors, perhaps integrating with other Google wearable health products, where we are seeing many of their current ventures, including introducing their own smart rings.

Much research has focused on things that can be sensed from common touchpoints on the head, which has included heart rate, body temperature and galvanic skin response (skin moistness, which changes with, for example, stress), and even brain activation through EEG for example. With the current advances in consumer neurotechnology, we could easily see Smart Glasses that use EEG to track brain data in the nextfew years.

What the first medical evacuation from the International Space Station tells us about healthcare in space

Source: The Conversation – UK – By Kirsty Lindsay, Scientific Officer, Northumbria University, Newcastle

Nasa

For the first time in 25 years of continuous crewed operations, an astronaut has been medically evacuated from the International Space Station (ISS). The Crew-11 mission ended when a SpaceX Dragon capsule brought the four astronauts of Crew 11 home following a medical incident in early January 2026.

To protect the crewmember’s privacy, Nasa hasn’t yet disclosed details about what happened – and this article won’t speculate. But the evacuation raises a question worth exploring: how do astronauts stay healthy in space, and why is this early evacuation so unusual?

Astronauts undergo rigorous medical screening before selection. They are assessed for conditions that might worsen in microgravity, evaluated for psychological resilience, and monitored throughout their careers.

Although modelling suggests a medical emergency could be expected roughly every three years on the ISS, serious issues are remarkably rare in practice.

Every ISS mission includes medical support both in space and on the ground. Each crew has a designated Crew Medical Officer – sometimes a qualified doctor, sometimes someone with extensive training in space medicine procedures. They can perform basic examinations, administer medications, and conduct telemedicine consultations with specialists on Earth.

What health issues do occur in space?

A 2015 study found that medication use on the ISS was relatively low, with roughly ten doses of over-the-counter medication taken per astronaut per week, most of which are for common, manageable conditions, such as:

  • Skin irritation is the most frequently reported medical issue in spaceflight. A recent systematic review found that space-related dermatoses including dry skin, rashes, hypersensitivity reactions, and impaired wound healing – occur at rates approximately 25 times higher than on Earth. The cold, dry, low-humidity spacecraft environment exacerbates these problems, and hygiene is limited to wet wipes and rinse-less products for months at a time.

  • Congestion and headaches affect most astronauts, particularly early in a mission. Without gravity pulling fluids downward, blood shifts toward the head, causing a puffy face and stuffy nose – what astronauts call “space sniffles.” This can trigger headaches, reduced appetite, and poor sleep.

  • Sleep disruption is widespread. The ISS orbits Earth every 90 minutes, creating 16 sunrises and sunsets over 24 hours, which disrupts circadian rhythms. Combined with equipment noise, reduced personal space, and the stress of spaceflight, astronauts typically get one to two hours less sleep per night compared to on Earth.

  • Musculoskeletal injuries are surprisingly common. A Nasa study catalogued 219 in-flight injuries across the US space programme, with an incidence of roughly 0.02 per flight day.

  • Hand injuries were most frequent, mostly small cuts from moving between modules or handling equipment. But exercise, ironically the leading countermeasure designed to protect astronauts’ bones and muscles, is now the leading source of injuries on the ISS.

Astronauts exercise for around two hours each day to combat bone and muscle loss and cardiovascular deconditioning in microgravity. Without gravity’s constant load, bones can lose about 1% of their density per month, particularly in the legs, hips, and spine.

Yet this essential countermeasure carries its own risks. Spacewalks present additional hazards – the study found 0.26 injuries per extravehicular activity, often caused by spacesuit components.

Research continues to make these countermeasures safer and more effective. At Northumbria University, the Aerospace Medicine and Rehabilitation Laboratory works with European Space Agency, Nasa, Canadian Space Agency and private spaceflight companies including SpaceX to develop exercise-based interventions to protect astronaut health. The research team are pioneering approaches to maintain physical function during longer missions and accelerate recovery on return to Earth.

Space-specific conditions

Some health issues are unique to spaceflight. Spaceflight Associated Neuro-ocular Syndrome (SANS) affects up to 70% of astronauts on long-duration missions. The headward fluid shift changes pressure in the eye, leading to optic nerve flattening and vision changes that can persist for years after returning to Earth.

Perhaps most striking was an incident reported in 2020, when a blood clot was discovered in an astronaut’s jugular vein during a routine research ultrasound. The astronaut had no symptoms; the clot was found by chance. In what became the ultimate telemedicine case, doctors on Earth guided treatment over more than 90 days.

Blood thinners were administered, additional medication was sent on a resupply vessel, and the astronaut performed their own ultrasound scans with radiologists directing from hundreds of kilometres below. They completed their mission and returned safely at the end of their mission without any health consequences.

The Crew-11 evacuation demonstrates that space agencies prioritise crew safety above all else. As missions move beyond low Earth orbit into deep space, new approaches to medical care will be needed – referred to as Earth Independent Medical Operations, potentially using AI to assist crew medical officers alongside lessons from current missions.

That this is the first expedited medical evacuation in 25 years highlights how effectively space medicine has developed. But it’s also a reminder that space remains inherently challenging for human biology, and sometimes there really is no place like home.

Iran’s latest internet blackout extends to phones and Starlink

Source: The Conversation – USA – By Amanda Meng, Senior Research Scientist, College of Computing, Georgia Institute of Technology

Protesters have filled the streets in Iranian cities, but the regime’s internet shutdown means little news gets in or out of the country. MAHSA/Middle East Images/AFP via Getty Images

The Iranian regime’s internet shutdown, initiated on Jan. 8, 2026, has severely diminished the flow of information out of the country. Without internet access, little news about the national protests that flared between Dec. 30, 2025, and Jan. 13, 2026, and the regime’s violent crackdown has reached the world. Many digital rights and internet monitoring groups have assessed the current shutdown to be the most sophisticated and most severe in Iran’s history.

We are a social scientist and two computer scientists at the Georgia Institute of Technology’s Internet Intelligence Lab who study internet connectivity.

Through the Internet Outage Detection and Analysis project, we have been measuring internet connectivity globally since 2011. The project was motivated by the internet shutdowns during the Arab Spring mass protests that began in December 2010 against Middle Eastern and North African regimes.

The project provides a public dashboard of internet connectivity measurements. Its long view of global internet connectivity offers insight into the Iranian regime’s developing sophistication in controlling information and shutting down the internet in the country.

Our measurements show that Iran has been in a complete internet shutdown since Jan. 8. This is longer than the 48½-hour shutdown in June 2025 during the Israel-Iran war and surpasses the duration of the November 2019 shutdown that lasted almost seven days. Compared to the two weeks of nightly mobile phone network shutdowns in September to October of 2022 during the Women, Life, Freedom protests, this shutdown is more complete by also closing down fixed-line connectivity.

Measuring internet connectivity

The Internet Outage Detection and Analysis project measures global internet connectivity through three signals related to internet infrastructure: routing announcements, active probing and internet background noise.

Core routers, unlike the router in your home, are responsible for directing traffic to and from networks. Routing announcements are how they communicate with each other. If a nation’s network of routers stop making these announcements, the network will disappear from the global internet.

We also measure the responsiveness of networks through probing. To create the probing signal, we continuously ping devices in millions of networks around the globe. Most devices are designed to automatically respond to these pings by echoing them back to the sender. We collect these responses and label networks as “connected/active.”

A tool we use dubbed “network telescope” captures internet background noise – traffic generated by hundreds of thousands of internet hosts worldwide. A drop in this signal can indicate an outage.

A history of shutdowns

The first nationwide shutdown that the Internet Outage Detection and Analysis project observed in Iran was during the “Bloody November” uprising that happened in 2019. During that shutdown, the primary method the regime used was turning off routing announcements, which stopped all traffic between routers. This is a blunt force tool that makes the internet essentially go dark; no connectivity is possible for affected networks.

However, our measurement reporting showed differences in signal-drop patterns among the three data sources we track. These patterns demonstrate the regime’s adoption of diverse disconnection mechanisms and large differences in the timing of disconnection by various Iranian internet service providers (ISPs).

This reporting also showed evidence that the 2019 blackout was not complete and some people were able to circumvent it. Nevertheless, as documented by Amnesty International, the internet darkness created a “web of impunity” that allowed the regime to violate international human rights law without any accountability.

In September 2022, the Women, Life, Freedom protests erupted after the killing of Mahsa Amini in state custody. To suppress the nationwide mobilization without exacting a high cost, the Iranian regime implemented nightly shutdowns affecting only mobile networks. Keeping fixed-line internet connections online limited the impact of these shutdowns to mitigate the economic, political and social costs.

These nightly internet curfews lasted about two weeks. During this time the regime implemented other forms of censorship, specifically blocking applications to further control the information environment and to prevent access to technologies for circumventing censorship.

In June 2025, the Israel-Iran war began and we observed initial degradation in internet connectivity, which often occurs during times of conflict, when internet and power infrastructure are affected by missile attacks. The Iranian regime shut down the internet over four days, citing national security as its rationale.

That time, the regime did not use routing announcements to implement the shutdown. Our measurement data shows that routing announcements were largely unaffected. Instead, the Iranian regime implemented the shutdown by interfering with key protocols that allow the internet to function, including transport layer security and the domain name system.

The regime used these techniques to shut off Iran’s connectivity with the global internet while allowing specific, sanctioned access in a policy called whitelisting. This strategy shows an increased sophistication in how the Iranian regime implements shutdowns and controls the flow of information.

Organizations that support digital human rights in Iran report that some Iranians were able to circumvent the shutdown using virtual private networks and various censorship-resilient technologies such as peer-to-peer networks.

The Iranian regime has targeted Starlink satellite internet service in its internet shutdown.

Jan. 8, 2026

On Dec. 30, 2025, the Internet Outage Detection and Analysis project team received reports of internet disruptions amid the start of nationwide protests. At 8 p.m. Iran Standard Time on Jan. 8, 2026, the Iranian regime shut down the internet. Our measurements show a nominal amount of responsiveness to our active probing, about 3%. This small amount could be an artifact of our measurements or lingering connectivity for whitelisted access, for example for Iranian government officials and services.

Outside of very limited whitelisted connectivity, digital human rights groups reported severely limited access to the internet both internationally and domestically. According to digital rights group Project Ainita, the Iranian regime implemented the shutdown by interfering with transport layer security and the domain name system. In addition, landline phone calls have been only intermittently available.

Aside from these more sophisticated techniques, this shutdown evokes the Bloody November shutdown of 2019 in that it has been ordered during a time of protest with mass civilian casualties.

Jammed satellites

Since Russia’s full-scale invasion of Ukraine in 2022, low Earth orbit satellite services, such as Starlink, can help people maintain internet connectivity during outages and government-ordered shutdowns. These satellite services can allow users to bypass damaged or state-censored terrestrial internet infrastructure.

However, accessing the internet via satellite services during a shutdown is not without risk. User terminals communicate with satellites via radio frequency links that can be detected through surveillance, for example from planes or drones, potentially exposing users’ locations and putting them at risk of being identified. Currently, the Iranian regime is using jammers to degrade the Starlink connection.

One of the most significant barriers to connecting users in Iran to satellite services is a logistical one. Providing connectivity via Starlink’s service would require distributing a large number of user terminals within the country, a feat that would be difficult because the devices are likely to be considered illegal contraband by the government. This severely limits the scale at which such services can be adopted.

Recent technological developments, however, may partially mitigate this challenge. Starlink’s direct-to-cell capability, which aims to provide LTE cellular connectivity directly to ordinary cellphones, could reduce dependence on specialized hardware. If they become widely available, such systems would allow users to connect using common devices already in circulation, sidestepping one of the most difficult barriers to providing connectivity.

Like other radio-based communications, however, direct-to-cell connectivity would remain vulnerable to signal jamming and other forms of electronic interference by the government.

For the time being, the Iranian regime controls the country’s internet infrastructure, which means it still has a virtual off switch.

Raccoons break into liquor stores, scale skyscrapers and pick locks – studying their clever brains can clarify human intelligence, too

When a curious raccoon broke into an Ashland, Virginia, liquor store in December 2025, sampled the stock and passed out on the bathroom floor, the story went viral within minutes. The local animal shelter’s Facebook post was picked up by national and international outlets and quickly inspired raccoon-themed cocktails, “trashed panda” merchandise and even a cameo on “Saturday Night Live.”

For me, the story hit close to home. The store that hosted this inebriated bandit sits just blocks from the small behavioral neuroscience laboratory where I began investigating raccoon brains about 15 years ago. Although the so-called drunken raccoon made questionable decisions after breaking into the liquor store, the species – Procyon lotor – is known for its impressive intelligence, curiosity and problem-solving skills.

Despite being one of the most intriguing mammals living alongside humans, raccoons have avoided the scientific spotlight. Why aren’t more neuroscientists and psychologists studying raccoons? What have researchers missed about the mammalian brain by focusing on rodents instead?

Someone had a good time.

Why raccoons aren’t lab staples

In the U.S., it is estimated that laboratories use more than 100 million rodents, including mice and rats, each year. Rodents are ideal for research because they reproduce easily and adapt well to confinement. Scientists have tailored extensive research tools to study them. Long before rats dominated psychology labs, raccoons were actually a leading candidate for animal models of problem-solving and intelligence.

That ended when scientists realized they’d met their cognitive match. In one study, researchers reported that all raccoon participants escaped through the laboratory ventilation system.

Unsurprisingly, scientists promptly shifted to rodents. Practicality – not scientific suitability – ultimately crowned the rat as king of the laboratory. I have studied rats for decades, and I can confirm that none have ever disappeared into the ceiling.

Neither pet nor pest

Humans have an ambivalent relationship with raccoons. They appear too wild to be domesticated, too endearing to be treated purely as pests and too ubiquitous to be considered exotic wildlife. Even President Calvin Coolidge, who famously received a raccoon intended for the dinner table from a supporter in Mississippi, ended up keeping it as a beloved White House pet.

And the role confusion continues today with glimpses of humanlike behaviors in raccoons as they enter our living spaces. One report described raccoons interacting with playground equipment at a child care center on Canada’s west coast in ways similar to human children, and even breaking into classrooms as if they were auditing the morning lesson.

Inspired by Montessori education principles, I visited a raccoon rehabilitation center in Saskatoon, Canada, called Bandit Ranch Rehab a few years ago. After introducing young raccoons to slinkies, puzzles and blocks, I sat in awe as they interacted with these objects with the focused enthusiasm of preschoolers on a mission.

This interspecies confusion seems to be mutual. Recent evidence suggests that urban raccoons are becoming increasingly tolerant of humans, especially when it suits them. But they are quick to leave when curiosity or opportunity calls.

Raccoon imagination

The drunken Ashland raccoon captured global attention because it fit the narrative people have projected onto the species: mischievous, opportunistic, clever and more than a little humanlike. But their sophisticated brains and mental capacities, aligning more with primates than other mammals, are even more intriguing.

Early behavioral research suggested that raccoons can learn a task, walk away and later return to solve it accurately – as if having mentally rehearsed the solution. In contrast, other species, including dogs and rats, needed to maintain continuous focus. Scientists have speculated that raccoons have mental imagery capabilities similar to humans.

When a rogue raccoon scaled a 25-story skyscraper in Minneapolis several years ago, I couldn’t help but wonder what that animal was anticipating at the top. Do raccoons form internal representations of future outcomes? And if so, how much agency and foresight do they bring to their decisions?

To answer these questions, I have collaborated with wildlife biologists, veterinarians and neuroscientists around the country to study what may be one of the most underestimated and understudied brains in the animal kingdom.

What’s going on inside the raccoon brain?

Working with neuroscientist Suzana Herculano-Houzel, my laboratory at the University of Richmond has found that raccoons pack an astonishing number of neurons – an amount comparable to primates – into their brains. Scaled up to size, a raccoon brain would contain roughly the same number of neurons as a human brain.

We also found that raccoons possess specialized fast-conducting brain cells known as von Economo neurons, which are also found in humans, other great apes and a few additional large-brained mammals. In apes, these neurons appear in both the insula – a part of the brain important for processing internal body states – and the anterior cingulate, which plays a key role in emotional regulation. In raccoons, these neurons are present only in the insula and not in the anterior cingulate.

This neural arrangement may help explain the species’ striking combination of clever problem-solving and rapid decision-making during exploration – frequently leading to risky behaviors that can have unfortunate consequences. These findings raise the possibility that raccoon neuroscience could offer useful insights into the neural foundations of impulse control and distracted attention.

In collaboration with ecologist Sara Benson-Abram’s research team, we also found that raccoons with more sophisticated cognitive abilities had more neural cells in the hippocampus, reinforcing the idea that their learning and memory capacities map onto similar brain systems as those in people. Taxi drivers in London, who frequently use their knowledge of the 25,000 streets in London, also have a larger hippocampal area.

In addition to their impressive brains, raccoons’ dexterous hands play a key role in their cognitively creative escapades. Indeed, researchers have found that raccoon forepaws are mapped onto their cerebral cortex – the outer layer of the brain – in a similar manner as human hands. Both take up a lot of real estate in the brain. As journalist Carl Zimmer wrote, “The hand is where the mind meets the world.”

What raccoons can teach us about the human brain

As I argue in my upcoming book “Wild Brains,” understanding raccoon intelligence requires observing them in the environments they choose – not confining them to the small, simple spaces that suit rats and mice. So-called living laboratories that monitor wildlife without restricting their behavior may be scientists’ best chance at unlocking the secrets of this species’ remarkable mind.

In my graduate training, I was taught to avoid anthropomorphizing animal research subjects – to resist the temptation to project human thoughts and emotions onto nonhuman minds, because human brains likely contribute to uniquely human cognitive and emotional experiences. But primatologist Frans de Waal later introduced the useful counterpoint of anthropodenial: the mistaken assumption that animals cannot share emotional or cognitive capacities with humans simply because they are not human.

The drunken Ashland raccoon captured global attention not just because the story was funny, but because it felt familiar. People recognized something of themselves in this curious, impulsive, problem-solving animal navigating a very human environment. A willingness to lean away from anthropodenial – while remaining grounded in rigorous science – may open new paths for understanding raccoon intelligence and, ultimately, the wonderfully complex human brain.

American farmers, who once fed the world, face a volatile global market with diminishing federal backing

President Donald Trump appears to have upended an 85-year relationship between American farmers and the United States’ global exercise of power. But that link has been fraying since the end of the Cold War, and Trump’s moves are just another big step.

During World War II, the U.S. government tied agriculture to foreign policy by using taxpayer dollars to buy food from American farmers and send it to hungry allies abroad. This agricultural diplomacy continued into the Cold War through programs such as the Marshall Plan to rebuild European agriculture, Food for Peace to send surplus U.S. food to hungry allies, and the U.S. Agency for International Development, which aimed to make food aid and agricultural development permanent components of U.S. foreign policy.

During that period, the United States also participated in multinational partnerships to set global production goals and trade guidelines to promote the international movement of food – including the U.N.’s Food and Agriculture Organization, the International Wheat Agreement and the General Agreement on Tariffs and Trade.

When U.S. farmers faced labor shortfalls, the federal government created guest-worker programs that provided critical hands in the fields, most often from Mexico and the Caribbean.

At the end of World War II, the U.S. government recognized that farmers could not just rely on domestic agricultural subsidies, including production limits, price supports and crop insurance, for prosperity. American farmers’ well-being instead depended on the rest of the world.

Since returning to office in January 2025, Trump has dismantled the U.S. Agency for International Development. His administration has also aggressively detained and deported suspected noncitizens living and working in the U.S., including farmworkers. And he has imposed tariffs that caused U.S. trading partners to retaliate, slashing international demand for U.S. agricultural products.

Trump’s actions follow diplomatic and agricultural transformations that I research, and which began with the fall of the Soviet Union in 1991.

Feed the world, save the farm

Even before the nation’s founding, farmers in what would become the United States staked their livelihood on international networks of labor, plants and animals, and trade.

Cotton was the most prominent early example of these relationships, and by the 19th century wheat farmers depended on expanding transportation networks to move their goods within the country and overseas.

But fears that international trade could create economic uncertainty limited American farmers’ interest in overseas markets. The Great Depression in the 1930s reinforced skepticism of international markets, which many farmers and policymakers saw as the principal cause of the economic downturn.

World War II forced them to change their view. The Lend-Lease Act, passed in March 1941, aimed to keep the United States out of the war by providing supplies, weapons and equipment to Britain and its allies. Importantly for farmers, the act created a surge in demand for food.

And after Congress declared war in December 1941, the need to feed U.S. and allied troops abroad pushed demand for farm products ever higher. Food took on a significance beyond satisfying a wartime need: The Soviet Union, for example, made special requests for butter. U.S. soldiers wrote about the special bond created by seeing milk and eggs from a hometown dairy, and Europeans who received food under the Lend-Lease Act embraced large cans of condensed milk with sky-blue labels as if they were talismans.

Another war ends

But despite their critical contribution to the war, American farmers worried that the familiar pattern of postwar recession would repeat once Germany and Japan had surrendered.

Congress fulfilled farmers’ fears of an economic collapse by sharply reducing its food purchases as soon as the war ended in the summer of 1945. In 1946, Congress responded weakly to mounting overseas food needs.

More action waited until 1948, when Congress recognized communism’s growing appeal in Europe amid an underfunded postwar reconstruction effort. The Marshall Plan’s more robust promise of food and other resources was intended to counter Soviet influence.

Sending American food overseas through postwar rehabilitation and development programs caused farm revenue to surge. It proved that foreign markets could create prosperity for American farmers, while food and agriculture’s importance to postwar reconstruction in Europe and Asia cemented their importance in U.S. foreign policy.

Farmers in the modern world

Farmers’ contribution to the Cold War shored up their cultural and political importance in a rapidly industrializing and urbanizing United States. The Midwestern farm became an aspirational symbol used by the State Department to encourage European refugees to emigrate to the U.S. after World War II.

American farmers volunteered to be amateur diplomats, sharing methods and technologies with their agricultural counterparts around the world.

By the 1950s, delegations of Soviet officials were traveling to the Midwest, including Soviet premier Nikita Khrushchev’s excursion to Iowa in 1959. U.S. farmers reciprocated with tours of the Soviet Union. Young Americans who had grown up on farms moved abroad to live with host families, working their properties and informally sharing U.S. agricultural methods. Certain that their land and techniques were superior to those of their overseas peers, U.S. farmers felt obligated to share their wisdom with the rest of the world.

The collapse of the Soviet Union undermined the central purpose for the United States’ agricultural diplomacy. But a growing global appetite for meat in the 1990s helped make up some of the difference.

U.S. farmers shifted crops from wheat to corn and soybeans to feed growing numbers of livestock around the world. They used newly available genetically engineered seeds that promised unprecedented yields.

Expecting these transformations to financially benefit American farmers and seeing little need to preserve Cold War-era international cooperation, the U.S. government changed its trade policy from collaborating on global trade to making it more of a competition.

The George H.W. Bush and Clinton administrations crafted the North American Free Trade Agreement and the World Trade Organization to replace the general agreement on trade and tariffs. They assumed American farmers’ past preeminence would continue to increase farm revenues even as global economic forces shifted.

But U.S. farmers have faced higher costs for seeds and fertilizer, as well as new international competitors such as Brazil. With a diminished competitive advantage and the loss of the Cold War’s cooperative infrastructure, U.S. farmers now face a more volatile global market that will likely require greater government support through subsidies rather than offering prosperity through commerce.

That includes the Trump administration’s December 2025 announcement of a US$12 billion farmer bailout. As Trump’s trade wars continue, they show that the U.S. government is no longer fostering a global agricultural market in which U.S. farmers enjoy a trade advantage or government protection – even if they retain some cultural and political significance in the 21st century.

Deep reading can boost your critical thinking and help you resist misinformation – here’s how to build the skill

The average American checks their phone over 140 times a day, clocking an average of 4.5 hours of daily use, with 57% of people admitting they’re “addicted” to their phone. Tech companies, influencers and other content creators compete for all that attention, which has incentivized the rise of misinformation.

Considering this challenging information landscape, strong critical reading skills are as relevant and necessary as they’ve ever been.

Unfortunately, literacy continues to be a serious concern. Reading comprehension scores have continued to decline. The majority of Gen Z parents are not reading aloud to their young children because they view it as a chore. Many college students cannot make it through an entire book.

With their endless scrolling and easy reposting and sharing of content, social media platforms are designed to encourage passive engagement that people use to relieve boredom and escape stress.

As a cognitive scientist and a literacy expert, we research the ways people process information through reading. Based on our work, we believe that deep reading can be an effective way to counter misinformation as well as reduce stress and loneliness. It can be tough to go deeper than a speedy skim, but there are strategies you can use to strengthen important reading skills.

Deep reading versus doomscrolling

People use smartphones and social media for a variety of reasons, such as to relieve boredom, seek attention, make connections and share news. The infinite amount of information available at your fingertips can lead to information overload, interfering with how you pay attention and make decisions. Research from cognitive science helps to explain how scrolling trains your brain to think passively.

To keep people engaged, social media algorithms feed people content similar to what they’ve already engaged with, reinforcing users’ beliefs with similar posts. Repeated exposure to information increases its believability, especially if different sources repeat the information, an effect known as illusory truth.

Deep reading, on the other hand, refers to the intentional process of engaging with information in critical, analytical and empathetic ways. It involves making inferences, drawing connections, engaging with different perspectives and questioning possible interpretations.

Deep reading does require effort. It can trigger negative feelings like irritation or confusion, and it can very often feel unpleasant. The important question, then: Why would anyone choose the hard work of deep reading when they can just scroll and skim?

Motivating mental effort

Mindless scrolling may come with unintended consequences. Smartphone and social media use is associated with increased boredom and loneliness. And doomscrolling is related to higher levels of existential anxiety and misanthropy.

In contrast, attention and effort, despite being exhausting, can deepen your sense of purpose and strengthen social connection. People also feel motivated to complete tasks that help them pursue personal goals, especially when these tasks are recognized by others. For these reasons, sharing books may be one tool to promote deep reading.

One example is a teacher who guides students through longer texts, like novels, paired with active discussions about the books to reinforce comprehension and interpretation. While the debate over the ongoing practice of assigning excerpts over full books in schools continues, evidence does suggest that sustained reading in social settings can promote lifelong enjoyment in reading.

With social connection in mind, social media can actually be used as a positive tool. BookTok is a popular online community of people who use TikTok to discuss and recommend books. Fans post in-depth analyses of “K-Pop Demon Hunters” and other movies or shows, demonstrating that close analysis still has a place in the endless scroll of social media.

Slowing yourself down to read deeply

There are steps you can take to meaningfully engage with the constant stream of information you encounter. Of course, this process can be taxing, and people only have so much effort and attention to expend. It’s important to both recognize your limited cognitive resources and be intentional about how you direct those resources.

Simply being aware of how digital reading practices shape your brain can encourage new attitudes and habits toward how you consume information. Just pausing can reduce susceptibility to misinformation. Taking a few extra seconds to consciously judge information can counteract illusory truth, indicating that intentionally slowing down even just a bit can be beneficial.

Reading deeply means being able to intentionally choose when to read at different speeds, slowing down as needed to wrestle with difficult passages, savor striking prose, critically evaluate information, and reflect on the meaning of a text. It involves entering into a dialogue with the text rather than gleaning information.

Awareness does not mean that you never doomscroll at the end of a long day. But it does mean becoming conscious of the need to also stick with a single text more frequently and to engage with different perspectives.

You can start small, perhaps with poems, short stories or essays, before moving up to longer texts. Partner with a friend or family member and set a goal to read a full-length novel or nonfiction book. Accomplish that goal in small chunks, such as reading one chapter a day and discussing what you read with your reading buddy. Practicing deep reading, such as reading novels, can open you up to new perspectives and ideas that you can explore in conversation with others, in person or even on TikTok.

Colorado ranchers and consumers can team up to make beef supply chains more sustainable

Cowboys guided a herd of longhorn cattle through downtown Denver to celebrate the opening of the annual National Western Stock Show on Jan. 8, 2026. As ranchers bring their best cattle to compete for blue ribbons over the course of this month, it’s a good time to consider whether beef production can be part of a circular economy.

Circularity is an economic model where raw materials are responsibly sourced, waste products are put to best use and the system maximizes ecosystem functioning and human well-being.

As with most human activities, beef production provides a valuable contribution to human health while also impacting the natural environment, sometimes in negative ways.

We are innovators and researchers who live in Colorado and study the beef supply chain. Our work broadly focuses on investigating ways to make beef production more circular and sustainable.

Kim Stackhouse-Lawson and Sara Place are experts in cow burps and technologies to mitigate the methane associated with them. Jennifer Martin is an expert in meat processing and supply chains for byproducts like organ meats. Jordan Kraft Lambert is an expert in commercializing technologies that help farmers and ranchers steward the environment while feeding the world.

Beef is a source of complete protein. It has the full complement of amino acids humans need to build muscle and is a rich source of vitamin B12, which is necessary to ensure nervous system function and red blood cell formation. Beef produced in the U.S. each year meets the total protein needs of 40 million people and provides enough B12 to meet the needs of 137 million people, according to research.

In 2019, U.S. beef cattle production comprised about 3.7% of the country’s greenhouse gas emissions. Beef cattle production is also responsible for approximately 5% of U.S. water withdrawn from surface or groundwater, and 0.7% of the nation’s fossil fuel energy use.

New tech to reduce environmental impact

Cows are able to digest tough, fibrous plant material that humans, pigs and chickens can’t. This makes them an important part of a circular economy because they can digest what would otherwise be considered waste from other industries, like the grain left over from making beer and almond hulls from almond milk. By using these ingredients to feed cattle instead of letting it rot in landfills, U.S. feedlots decreased the amount of human-edible feeds required to produce more beef protein.

When cattle are being fed waste products like almond hulls and spent grain, it’s easy for producers to include feed additives, like herbs and custom-made molecules. These additions may reduce the cows’ methane production by changing how the microbes in their stomachs process carbohydrates.

For the same reason that cows can digest what would otherwise be considered waste, cows are able to eat grass. Grazing is important in dry regions like the mountains and high plains of Colorado. If the grass isn’t removed via grazing, it dries and becomes tinder for wildfire. In addition, many of these mountainous areas are too cold, rocky and steep to grow crops. Grazing can turn land that would otherwise be difficult to farm into food-producing land.

Until now, grazing required physical fences, which are costly to maintain and limit wildlife movement. But new technologies like virtual fencing allow Western Slope ranchers to use their smartphones to set digital boundaries. A collar on the cow beeps and buzzes to tell the cows where to go. Virtual boundaries are easy to change and visible only to the cow; thus, they support more environmentally-friendly grazing practices, protect streams and wildlife habitat and reduce wildfire fuel in dry seasons. While our recent research shows that this technology needs more development, it could be an important tool for beef’s role in a circular economy.

Beyond steak: Organ meats, pet treats and leather

In our experience, many U.S. consumers rarely eat cuts beyond steaks and ground beef — often due to a bad first experience with organ meats, like liver, or unfamiliarity with how to cook lesser-known cuts, like heart.

When customers won’t buy these cuts, Colorado’s beef producers who sell online or at farmers markets have to send them to the landfill. That costs the producer money and wastes the water, land and feed used to make these cuts.

Studies show that these cuts are among the most nutrient-dense parts of the animal, providing high levels of iron, B vitamins, choline and and other micronutrients. Making use of these lesser-known cuts can reduce emissions by using more of the animal and keep edible meat out of landfills, where it would otherwise rot, releasing greenhouse gases.

This does not mean anyone has to suffer through a meal of rubbery liver to save the planet. Many cultures globally value organ dishes, and U.S. tastes are expanding to include foods like lengua tacos made from beef tongue. Meanwhile, cooking tools such as sous vide can improve tenderness and juiciness by holding meat at precise temperatures for longer times.

Pets also benefit from eating organ meats, so these cuts are a key ingredient in pet foods and treats.

Consumer fashion choices matter too. About 270 million bovine hides are produced globally each year, and about 70% are turned into leather. Due to insufficient demand, remaining hides are burned or sent to the landfill, both of which release greenhouse gases.

Rather than letting these hides rot, they can be turned into leather, a durable, breathable and biodegradable high-performance material. When consumers choose to buy genuine leather boots, belts and car seats, they’re engaging in the circular economy.

For these reasons, Colorado State University is hosting Future Cowboy on Jan. 25, 2026, at the National Western Stock Show. It’s an event that lets Colorado foodies, fashionistas and cattle producers come together to explore circularity firsthand. The event will feature a leather fashion show, a ranch technology showcase and an opportunity try chef-prepared bison tongue and beef heart.
