In recent weeks, powerful atmospheric river storms have swept across Washington, Oregon and California, unloading enormous amounts of rain. As rivers surged, they overtopped or breached multiple levees – those long, often unnoticed barriers holding floodwaters back from homes and towns.

Most of the time, levees don’t demand attention. They quietly do their job, year after year. But when storms intensify, levees suddenly matter in a very personal way. They can determine whether a neighborhood stays dry or ends up underwater.

The damage in the West reflects a nationwide problem that has been building for decades. Across the U.S., levees are getting older while weather is getting more extreme. Many of these structures were never designed for the enormous responsibility they now carry.

As a civil engineer at Tufts University, I study water infrastructure, including the vulnerability of levees and strategies for making them more resilient. My research also shows that when levees fail, the consequences don’t fall evenly on the population.

Levees became critical infrastructure almost by accident

Many people assume levees were built as part of modern, carefully engineered flood-control systems. In reality, many of the levees still in use today began much more humbly.

Decades ago, farmers built simple earthen embankments to protect their fields and livestock from seasonal flooding. These early levees were practical solutions, shaped by experience rather than formal engineering. They were not constructed using rigorous design standards, and they did not follow consistent construction or maintenance guidelines.

Over time, the landscape around these levees changed. Farmland gave way to neighborhoods. Roads, railways, factories and ports expanded into floodplains. Populations grew. What were once modest, local structures protecting farms gradually became the first line of defense for millions of people in homes and workplaces.

During the Great Mississippi Flood of 1927, the river poured over and broke through levees, flooding thousands of square miles of land. Both overtopping and a breach are visible in this photo.

Without much public debate or planning, these semi-engineered levees took on a critical and unintended role. The question that still lingers is whether they were ever prepared for it.

Vast, aging levee system now protecting millions

Today, the National Levee Database counts more than 24,000 miles (38,600 kilometers) of levees in the U.S., with an average age of about 61 years and many of them much older. Together, they protect over 23 million people, around 7 million buildings and nearly US$2 trillion in property value.

That’s an extraordinary level of responsibility for a system that is unevenly maintained with varying oversight. Some levees are inspected regularly. Others are owned by small local agencies or private entities with limited funding. In some cases, responsibility is unclear or fragmented.

One levee that was breached along the Green River in Washington state during storms in mid-December 2025 had been due for repairs for several years, but disagreements among governments had recently held up needed work, The Seattle Times reported. The breach forced thousands of people to evacuate

A map shows many breaches in the Midwest, as well as in Washington state and the Northeast.
Many states have at-risk levees. The map shows all levees in the U.S. National Levee Database (in red) and 478 levee segments where overtopping is known to have occurred in the previous 15 years (in blue).
S. Flynn, et al., 2025

The American Society of Civil Engineers’ 2025 Report Card for American Infrastructure, which I contributed to, gave the nation’s levees a D-plus grade, citing aging infrastructure, inconsistent monitoring and long-term underinvestment. A new dataset that colleagues and I created of levee damage includes 487 cases where rivers poured over levees, known as overtopping, in the past 15 years. That doesn’t mean levees are failing everywhere; it means that many are operating with little margin for error.

How levees fail

Levee failures are rarely sudden collapses. More often, they start quietly.

The most common reason levees fail is overtopping, when water from a river, stream or lake behind the levee flows over the top. Once that happens, erosion can begin on the landward side, weakening the structure from behind. What starts as a slow trickle can quickly grow into a breach, creating a large gap in the levee where water can pour in.

Two illustrations. One of overtopping points out that age, height and the materials used can weaken the levee, leading to a breach, which cuts into the levee allowing a faster, deeper steam of water to pour through.
An illustration shows the difference between overtopping and a breach, and some of the reasons a levee can fail.
S. Flynn et al., 2025

Atmospheric river storms make the risk of overtopping and breaches much higher. These storms deliver enormous amounts of rainfall across wide areas in a matter of hours, often combined with snowmelt. Rivers rise faster and stay high longer. Many levees were never designed for that kind of sustained pressure.

When a levee breaches, flooding can be rapid and deep, leaving little time for evacuation and causing damage that spreads far beyond the floodplain.

Who relies on levees today?

Millions of Americans live and work in area protected by levees, often without realizing it. Homes, schools, highways, rail corridors, ports and power facilities depend on the integrity of these structures.

A recent national study found that across the contiguous U.S., urban expansion into floodplains occurred more than twice as fast after levee construction as it did in surrounding counties, highlighting how levees can affect communities’ perception of danger.

In fact, when levees fail, flooding can be worse than in areas without levees, because water rushes in quickly and drains slowly.

The risks are also uneven, shaped by history, economics and policy decisions.

That reality became painfully clear during an atmospheric river storm in March 2023 when a levee along California’s Pajaro River failed, flooding the town of Pajaro. Pajaro is home to many low-income farmworkers. Floodwaters forced hundreds of residents to evacuate, and some people were trapped as water levels rose.

How the Pajaro Valley flooded after intense rainfall from an atmospheric river in March 2023, breaching a levee protecting a small California town.

What made the disaster especially troubling was what emerged afterward. Officials and engineers had known for decades that the Pajaro River levee was vulnerable. Reports documented its weaknesses, but repairs were repeatedly delayed.

Interviews by The Los Angeles Times and public records showed that part of the reason was financial. Decision-makers did not prioritize investing in a levee system protecting the low-income community. The risk was known, but the protection was deferred.

Pajaro is not an isolated case. Across the country, disadvantaged communities and communities of color are more likely to rely on older levees or levees that are not part of major federal programs. Rural towns often depend on agricultural levees. Urban neighborhoods may rely on structures built for a much smaller population.

When levees fail, the impacts cascade, closing roads, knocking out power, contaminating water supplies and disrupting lives for years.

A map shows highest disparities in Idaho, Utah, Colorado, Iowa, Ohio, Tennessee, Georgia, North Carolina, Virginia, Maine, Massachusetts and Vermont.
Disparity refers to the percentage of each state’s residents protected by levees who are considered disadvantaged, based on the U.S. Council on Environmental Quality’s Climate and Economic Justice Screening Tool. All levees in the National Levee Database are counted.
F. Vahedifard et al., 2023

Why this moment matters

Advances in engineering, monitoring and risk assessment have improved how levees are evaluated and designed.

Hurricane Katrina marked a turning point in 2005 when its storm surge broke through levees protecting New Orleans. Hundreds of people died in the flooding. The disaster exposed the consequences of neglect and fragmented responsibility for levee upkeep.

At the same time, there has been real progress. Over the past two decades, significant federal investments have strengthened the condition and management of many of the nation’s levees, particularly through the work of federal agencies such as the U.S. Army Corps of Engineers.

Still, the legacy of decisions made decades ago remains, and climate change is raising the risks. Heavier rainfall, fast snowmelt and rising seas are pushing water control systems beyond what many levees were designed to handle. Events once considered rare are becoming more frequent.

As atmospheric rivers test levees in the West and flood risks grow nationwide, the challenge is no longer just technical. It’s about how society values protection, communicates risk and decides whose safety is prioritized.

Levees will continue to play a vital role in protecting communities. Understanding their history, and their limits, is essential as the storms of the future arrive.

What loving-kindness meditation is and how to practice it in the new year

Source: The Conversation – USA (3) – By Jeremy David Engels, Liberal Arts Endowed Professor of Communication, Penn State

Loving-kindness, the feeling cultivated in metta meditation, is very different from romantic love. Anna Sunderland Engels

A popular New Year’s resolution is to take up meditation – specifically mindfulness meditation. This is a healthy choice.

Regular mindfulness practice has been linked to many positive health benefits, including reduced stress and anxiety, better sleep and quicker healing after injury and illness. Mindfulness can help us to be present in a distracted world and to feel more at home in our bodies, and in our lives.

There are many different types of meditation. Some mindfulness practices ask meditators simply to sit with whatever thoughts, sensations or emotions arise without immediately reacting to them. Such meditations cultivate focus, while granting more freedom in how we respond to whatever events life throws at us.

Other meditations ask practitioners to deliberately focus on one emotion – for example, gratitude or love – to deepen the experience of that emotion. The purpose behind this type of meditation is to bring more gratitude, or more love, into one’s life. The more people meditate on love, the easier it is to experience this emotion even when not meditating.

One such meditation is known as “metta,” or loving-kindness. As a scholar of communication and mindfulness, as well as a longtime meditation teacher, I have both studied and practiced metta. Here is what loving-kindness means and how to try it out for yourself:

Unbounded, universal love

Loving-kindness, or metta, is the type of love which is practiced by Buddhists around the world. Like many forms of meditation today, there are both secular and religious forms of the practice. One does not need to be a Buddhist to practice loving-kindness. It is for anyone and everyone who wants to live more lovingly.

Loving-kindness, the feeling cultivated in metta meditation, is very different from romantic love. In the ancient Pali language, the word “metta” has two root meanings: The first is “gentle,” in the sense of a gentle spring rain that falls on young plants, nourishing them without discrimination. The second is “friend.”

Metta is limitless and unbounded love; it is gentle presence and universal friendliness. Metta practice is meant to grow people’s ability to be present for themselves and others without fail.

A guided loving-kindness meditation practice.

Metta is not reciprocal or conditional. It does not discriminate between us and them, rich and poor, educated and uneducated, popular or unpopular, worthy and unworthy. To practice metta is to give what I describe in my research as “the rarest and most precious gift” – a gift of love offered without any expectation of it being returned.

How to practice loving-kindness meditation

In the fifth century, a Sri Lankan monk, Buddhaghosa, composed an influential meditation text called the “Visuddhimagga,” or “The Path of Purification.” In this text, Buddhaghosa provides instructions for how to practice loving-kindness meditation. Contemporary teachers tend to adapt and modify his instructions.

The practice of loving-kindness often involves quietly reciting to oneself several traditional phrases designed to evoke metta, and visualizing the beings who will receive that loving-kindness.

Traditionally, the practice begins by sending loving kindness to ourselves. It is typical during this meditation to say:

May I be filled by loving-kindness

May I be safe from inner and outer dangers
May I be well in body and mind

May I be at ease and happy

After speaking these phrases, and feeling the emotions they evoke, next it’s common to direct loving-kindness toward someone – or something – else: It can be a beloved person, a dear friend, a pet, an animal, a favorite tree. The phrases become:

May you be filled by loving-kindness

May you be safe from inner and outer dangers

May you be well in body and mind

May you be at ease and happy

Next, this loving-kindness is directed to a wider circle of friends and loved ones: “May they …”

The final step is to gradually expand the circle of well wishes: including the people in our community and town, people everywhere, animals and all living beings, and the whole Earth. This last round of recitation begins: “May we …”

In this way, loving-kindness meditation practice opens the heart further and further into life, beginning with the meditator themselves.

Loving-kindness and mindful democracy

Clinical research shows that loving-kindness meditation has a positive effect on mental health, including lessening anxiety and depression, increasing life satisfaction and improving self-acceptance while reducing self-criticism. There is also evidence that loving-kindness meditation increases a sense of connection with other people.

The benefits of loving-kindness meditation are not just for the individual. In my research, I show that there are also tremendous benefits for society as a whole. Indeed, the practice of democracy requires us to work together with friends, strangers and even purported “opponents.” This is difficult to do if our hearts are full of hatred and resentment.

Each time meditators open their hearts in metta meditation, they prepare themselves to live more loving lives: for their own selves, and for all living beings.

AI agents arrived in 2025 – here’s what happened and the challenges ahead in 2026

Source: The Conversation – USA – By Thomas Şerban von Davier, Affiliated Faculty Member, Carnegie Mellon Institute for Strategy and Technology, Carnegie Mellon University

AI agents have emerged from the lab, bringing promise and peril. tadamichi/iStock via Getty Images

In artificial intelligence, 2025 marked a decisive shift. Systems once confined to research labs and prototypes began to appear as everyday tools. At the center of this transition was the rise of AI agents – AI systems that can use other software tools and act on their own.

While researchers have studied AI for more than 60 years, and the term “agent” has long been part of the field’s vocabulary, 2025 was the year the concept became concrete for developers and consumers alike.

AI agents moved from theory to infrastructure, reshaping how people interact with large language models, the systems that power chatbots like ChatGPT.

In 2025, the definition of AI agent shifted from the academic framing of systems that perceive, reason and act to AI company Anthropic’s description of large language models that are capable of using software tools and taking autonomous action. While large language models have long excelled at text-based responses, the recent change is their expanding capacity to act, using tools, calling APIs, coordinating with other systems and completing tasks independently.

This shift did not happen overnight. A key inflection point came in late 2024, when Anthropic released the Model Context Protocol. The protocol allowed developers to connect large language models to external tools in a standardized way, effectively giving models the ability to act beyond generating text. With that, the stage was set for 2025 to become the year of AI agents.

AI agents are a whole new ballgame compared with generative AI.

The milestones that defined 2025

The momentum accelerated quickly. In January, the release of Chinese model DeepSeek-R1 as an open-weight model disrupted assumptions about who could build high-performing large language models, briefly rattling markets and intensifying global competition. An open-weight model is an AI model whose training, reflected in values called weights, is publicly available. Throughout 2025, major U.S. labs such as OpenAI, Anthropic, Google and xAI released larger, high-performance models, while Chinese tech companies including Alibaba, Tencent, and DeepSeek expanded the open-model ecosystem to the point where the Chinese models have been downloaded more than American models.

Another turning point came in April, when Google introduced its Agent2Agent protocol. While Anthropic’s Model Context Protocol focused on how agents use tools, Agent2Agent addressed how agents communicate with each other. Crucially, the two protocols were designed to work together. Later in the year, both Anthropic and Google donated their protocols to the open-source software nonprofit Linux Foundation, cementing them as open standards rather than proprietary experiments.

These developments quickly found their way into consumer products. By mid-2025, “agentic browsers” began to appear. Tools such as Perplexity’s Comet, Browser Company’s Dia, OpenAI’s GPT Atlas, Copilot in Microsoft’s Edge, ASI X Inc.’s Fellou, MainFunc.ai’s Genspark, Opera’s Opera Neon and others reframed the browser as an active participant rather than a passive interface. For example, rather than helping you search for vacation details, it plays a part in booking the vacation.

At the same time, workflow builders like n8n and Google’s Antigravity lowered the technical barrier for creating custom agent systems beyond what has already happened with coding agents like Cursor and GitHub Copilot.

New power, new risks

As agents became more capable, their risks became harder to ignore. In November, Anthropic disclosed how its Claude Code agent had been misused to automate parts of a cyberattack. The incident illustrated a broader concern: By automating repetitive, technical work, AI agents can also lower the barrier for malicious activity.

This tension defined much of 2025. AI agents expanded what individuals and organizations could do, but they also amplified existing vulnerabilities. Systems that were once isolated text generators became interconnected, tool-using actors operating with little human oversight.

The business community is gearing up for multiagent systems.

What to watch for in 2026

Looking ahead, several open questions are likely to shape the next phase of AI agents.

One is benchmarks. Traditional benchmarks, which are like a structured exam with a series of questions and standardized scoring, work well for single models, but agents are composite systems made up of models, tools, memory and decision logic. Researchers increasingly want to evaluate not just outcomes, but processes. This would be like asking students to show their work, not just provide an answer.

Progress here will be critical for improving reliability and trust, and ensuring that an AI agent will perform the task at hand. One method is establishing clear definitions around AI agents and AI workflows. Organizations will need to map out exactly where AI will integrate into workflows or introduce new ones.

Another development to watch is governance. In late 2025, the Linux Foundation announced the creation of the Agentic AI Foundation, signaling an effort to establish shared standards and best practices. If successful, it could play a role like the World Wide Web Consortium in shaping an open, interoperable agent ecosystem.

There is also a growing debate over model size. While large, general-purpose models dominate headlines, smaller and more specialized models are often better suited to specific tasks. As agents become configurable consumer and business tools, whether through browsers or workflow management software, the power to choose the right model increasingly shifts to users rather than labs or corporations.

The challenges ahead

Despite the optimism, significant socio-technical challenges remain. Expanding data center infrastructure strains energy grids and affects local communities. In workplaces, agents raise concerns about automation, job displacement and surveillance.

From a security perspective, connecting models to tools and stacking agents together multiplies risks that are already unresolved in standalone large language models. Specifically, AI practitioners are addressing the dangers of indirect prompt injections, where prompts are hidden in open web spaces that are readable by AI agents and result in harmful or unintended actions.

Regulation is another unresolved issue. Compared with Europe and China, the United States has relatively limited oversight of algorithmic systems. As AI agents become embedded across digital life, questions about access, accountability and limits remain largely unanswered.

Meeting these challenges will require more than technical breakthroughs. It demands rigorous engineering practices, careful design and clear documentation of how systems work and fail. Only by treating AI agents as socio-technical systems rather than mere software components, I believe, can we build an AI ecosystem that is both innovative and safe.

The ‘sacred’ pledge that will power the relaunch of far-right militia Oath Keepers

Source: The Conversation – USA – By Alexander Lowie, Postdoctoral associate in Classical and Civic Education, University of Florida

Stewart Rhodes, the founder of the Oath Keepers, a far-right militia, announced in November 2025 that he will relaunch the group after it disbanded following his prison sentence in 2023.

Rhodes was sentenced to 18 years in prison for seditious conspiracy and other crimes committed during the U.S. Capitol riot on Jan. 6, 2021.

In January 2025, President Donald Trump granted clemency to the over 1,500 defendants convicted of crimes connected to the storming of the Capitol.

Trump did not pardon Rhodes – or some others found guilty of the most serious crimes on Jan. 6. He instead commuted Rhodes’ sentence to time served. Commutation only reduces the punishment for a crime, whereas a full pardon erases a conviction.

As a political anthropologist I study the Patriot movement, a collection of anti-government right-wing groups that include the Proud Boys, Oath Keepers and Moms for Liberty. I specialize in alt-right beliefs, and I have interviewed people active in groups that participated in the Capitol riot.

Rhodes’ plans to relaunch the Oath Keepers, largely composed of current and former military veterans and law enforcement officers, is important because it will serve as an outlet for those who have felt lost since his imprisonment. The group claimed it had over 40,000 dues-paying members at the height of its membership during Barack Obama’s presidency. I believe that many of these people will return to the group, empowered by the lack of any substantial punishment resulting from the pardons for crimes committed on Jan. 6.

In my interviews, I’ve found that military veterans are treated as privileged members of the Patriot movement. They are honored for their service and military training. And that’s why I believe many former Oath Keepers will rejoin the group – they are considered integral members.

Their oaths to serving the Constitution and the people of the United States are treated as sacred, binding members to an ideology that leads to action. This action includes supporting people in conflicts against federal agencies, organizing citizen-led disaster relief efforts, and protesting election results like on Jan. 6. The members’ strength results from their shared oath and the reverence they feel toward keeping it.

Who are the Oath Keepers?

Rhodes joined the Army after high school and served for three years before being honorably discharged after a parachuting accident in 1986. He then attended the University of Nevada and later graduated from Yale Law School in 2004. He founded the Oath Keepers in 2009.

Oath Keepers takes its name from the U.S military Oath of Enlistment, which states:

“I, , do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States …”

Informed by his law background, Rhodes places a particular emphasis on the part of the oath that states they will defend the Constitution against all enemies, foreign and domestic.

He developed a legal theory that justifies ignoring what he refers to as “unlawful orders” after witnessing the aftermath of Hurricane Katrina. Following the natural disaster, local law enforcement was assigned the task of confiscating guns, many of which officers say were stolen or found in abandoned homes.

Rhodes was alarmed, believing that the Second Amendment rights of citizens were being violated. Because of this, he argued that people who had military or law enforcement backgrounds had a legal duty to refuse what the group considers unlawful orders, including any that violated constitutionally protected rights, such as the right to bear arms.

In the Oath Keepers’ philosophy, anyone who violates these rights are domestic enemies to the Constitution. And if you follow the orders, you’ve violated your oath.

Explaining the origin of the group on the right-wing website “The Gateway Pundit” in November 2025, Rhodes said: “… we were attacked out of the gate, labeled anti-government, which is absurd because we’re defending the Constitution that established the federal government. We were labeled anti-government extremists, all kinds of nonsense because the elites want blind obedience in the police and military.”

Rebuilding and restructuring

In 2022, the nonprofit whistleblower site Distributed Denial of Secrets leaked more than 38,000 names on the Oath Keepers’ membership list.

The Anti-Defamation League estimated that nearly 400 of the names were active law enforcement officers, and that over 100 were serving in the military. Some of these members were investigated by their workplaces but never disciplined for their involvement with the group.

Some members who were not military or law enforcement did lose their jobs over their affiliation. But they held government-related positions, such as a Wisconsin alderman who resigned after he was identified as a member.

This breach of privacy, paired with the dissolution of the organization after Rhodes’ sentencing, will help shape the group going forward.

In his interview with “The Gateway Pundit,” where he announced the group’s relaunch, Rhodes said: “I want to make it clear, like I said, my goal would be to make it more cancel-proof than before. We’ll have resilient, redundant IT that makes it really difficult to take down. … And I want to make sure I get – put people in charge and leadership everywhere in the country so that, you know, down the road, if I’m taken out again, that it can still live on under good leadership without me being there.”

There was a similar shift in organizational structure with the Proud Boys in 2018. That’s when their founder, Gavin McInnes, stepped away from the organization. His departure came after a group of Proud Boys members were involved in a fight with anti-fascists in New York.

Prosecutors wanted to try the group as a gang. McInnes, therefore, distanced himself to support their defense that they weren’t in a gang or criminal organization. Ultimately, two of the members were sentenced to four years in prison for attempted gang assault charges.

Some Proud Boys members have told me they have since focused on creating local chapters, with in-person recruitment, that communicate on private messaging apps. They aim to protect themselves from legal classification as a gang. It also makes it harder for investigators or activist journalists to monitor them.

This is referred to as a cell style of organization, which is popular with insurgency groups. These groups are organized to rebel against authority and overthrow government structures. The cell organizational style does not have a robust hierarchy but instead produces smaller groups. They all adhere to the same ideology but may not be directly associated.

They may have a leader, but it’s often acknowledged that they are merely a figurehead, not someone giving direct orders. For the Proud Boys, this would be former leader Enrique Tarrio. Proud Boys members I’ve spoken to have referred to him as a “mascot” and not their leader.

Looking ahead

So what does the Rhodes interview indicate about the future of Oath Keepers?

Members will continue supporting Trump while also recruiting more retired military and law enforcement officers. They will create an organizational structure designed to outlive Rhodes. And based on my interactions with the far-right, I believe it’s likely they will create an organizational structure similar to that of the cell style for organizing.

Beyond that, they are going to try to own their IT, which includes hosting their websites and also using trusted online revenue generators.

This will likely provide added security, protecting their membership rolls while making it more difficult for law enforcement agencies to investigate them in the future.

Has the Fed fixed the economy yet? And other burning economic questions for 2026

Source: The Conversation – USA (2) – By D. Brian Blank, Associate Professor of Finance, Mississippi State University

The U.S. economy heads into 2026 in an unusual place: Inflation is down from its peak in mid-2022, growth has held up better than many expected, and yet American households say that things still feel shaky. Uncertainty is the watchword, especially with a major Supreme Court ruling on tariffs on the horizon.

To find out what’s coming next, The Conversation U.S. checked in with finance professors Brian Blank and Brandy Hadley, who study how businesses make decisions amid uncertainty. Their forecasts for 2025 and 2024 held up notably well. Here’s what they’re expecting from 2026 – and what that could mean for households, workers, investors and the Federal Reserve:

What’s next for the Federal Reserve?

The Fed closed out 2025 by slashing its benchmark interest rate by a quarter of a percentage point – the third cut in a year. The move reopened a familiar debate: Is the Fed’s easing cycle coming to an end, or does the cooling labor market signal a long-anticipated recession on the horizon?

While unemployment remains relatively low by historical standards, it has crept up modestly since 2023, and entry-level workers are starting to feel more pressure. What’s more, history reminds us that when unemployment rises, it can do so quickly. So economists are continuing to watch closely for signs of trouble.

So far, the broader labor market offers little evidence of widespread worsening, and the most recent employment report may even be more favorable than the top-line numbers made it appear. Layoffs remain low relative to the size of the workforce – though this isn’t uncommon – and more importantly, wage growth continues to hold up. That’s in spite of the economy adding fewer jobs than most periods outside of recessions.

Gross domestic product has been surprisingly resilient; it’s expected to continue growing faster than the pre-pandemic norm and on par with recent years. That said, the recent shutdown has prevented the government from collecting important economic data that Federal Reserve policymakers use to make their decisions. Does that raise the risk of a policy miscue and potential downturn? Probably. Still, we aren’t concerned yet.

And we aren’t alone, with many economists noting that low unemployment is more important than slow job growth. Other economists continue to signal caution without alarm.

Consumers, the largest driver of economic growth, continue spendingperhaps unsustainably – with strength becoming increasingly uneven. Delinquency rates – the share of borrowers who are behind on required loan payments in housing, autos and elsewherehave risen from historic lows, while savings balances have declined from unusually high post-pandemic levels. A more pronounced K-shaped pattern in household financial health has emerged, with older higher-income households benefiting from labor markets and already seeming past the worst financial hardship.

Still, other households are stretched, even as gas prices fall. This contributes to a continuing “vibecession,” a term popularized by Kyla Scanlon to describe the disconnect between strong aggregate economic data and weaker lived experiences amid economic growth. As lower-income households feel the pinch of tariffs, wealthier households continue to drive consumer spending.

For the Fed, that’s the puzzle: solid top-line numbers, growing pockets of stress and noisier data – all at once. With this unevenness and weakness in some sectors, the next big question is what could tip the balance toward a slowdown or another year of growth. And increasingly, all eyes are on AI.

Is artificial intelligence a bubble?

The dreaded “B-word” is popping up in AI market coverage more often, and comparisons to everything from the railroad boom to the dot-com era are increasingly common.

Stock prices in some technology firms undoubtedly look expensive as they rise faster than earnings. This may be because markets expect more rate cuts coming from the Fed soon, and it is also why companies are talking more about going public. In some ways, this looks similar to bubbles of the past. At the risk of repeating the four most dangerous words in investing: Is this time different?

Comparisons are always imperfect, so we won’t linger on the differences between this time and two decades ago when the dot-com bubble burst. Let’s instead focus on what we know about bubbles.

Economists often categorize bubbles into two types. Inflection bubbles are driven by genuine technological breakthroughs and ultimately transform the economy, even if they involve excess along the way. Think the internet or transcontinental railroad. Mean-reversion bubbles, by contrast, are fads that inflate and collapse without transforming the underlying industry. Some examples include the subprime mortgage crisis of 2008 and The South Sea Company collapse of 1720.

If AI represents a true technological inflection – and early productivity gains and rapid cost declines suggest it may – then the more important questions center on how this investment is being financed.

Debt is best suited for predictable, cash-generating investments, while equity is more appropriate for highly uncertain innovations. Private credit is riskier still and often signals that traditional financing is unavailable. So we’re watching bond markets and the capital structure of AI investment closely. This is particularly important given the growing reliance on debt financing in some large-scale infrastructure projects, especially at firms like Oracle and CoreWeave, which already seem overextended.

For now, caution, not panic, is warranted. Concentrated bets on single firms with limited revenues remain risky. At the same time, it may be premature to lose sleep over “technology companies” broadly defined or even investments in data centers. Innovation is diffusing across the economy, and these tech firms are all quite different. And, as always, if it helps you sleep better, changing your investments to safer bonds and cash is rarely a risky decision.

A quiet but meaningful shift is also underway beneath the surface. Market gains are beginning to broaden beyond mega-cap technology firms, the largest and most heavily weighted companies in major stock indexes. Financials, consumer discretionary companies and some industrials are benefiting from improving sentiment, cost efficiencies and the prospect of greater policy clarity ahead. Still, policy challenges remain ahead for AI and housing with midterms looming.

Will things ever feel affordable again?

Policymakers, economists and investors have increasingly shifted their focus from “inflation” to “affordability,” with housing remaining one of the largest pressure points for many Americans, particularly first-time buyers.

In some cases, housing costs have doubled as a share of income over the past decade, forcing households to delay purchases, take more risk or even give up on hopes of homeownership entirely. That pressure matters not only for housing itself, but for sentiment and consumption more broadly.

Still, there are early signs of relief: Rents have begun to decline in many markets, especially where new supply is coming online, like in Las Vegas, Atlanta and Austin, Texas. Local conditions such as zoning rules, housing supply, population growth and job markets continue to dominate, but even modest improvements in affordability can meaningfully affect household balance sheets and confidence.

Looking beyond the housing market, inflation has fallen considerably since 2021, but certain types of services, such as insurance, remain sticky. Immigration policy also plays an important role here, and changes to labor supply could influence wage pressures and inflation dynamics going forward.

There are real challenges ahead: high housing costs, uneven consumer health, fiscal pressures amid aging demographics and persistent geopolitical risks.

But there are also meaningful offsets: tentative rent declines, broadening equity market participation, falling AI costs and productivity gains that may help cool inflation without breaking the labor market.

Encouragingly, greater clarity on taxes, tariffs, regulation and monetary policy may arrive in the coming year. When it does, it could help unlock delayed business investment across multiple sectors, an outcome the Federal Reserve itself appears to be anticipating.

If there is one lesson worth emphasizing, it’s this: Uncertainty is always greater than anyone expects. As the oft-quoted baseball sage Yogi Berra memorably put it, “It’s tough to make predictions, especially about the future.”

Still, these forces may converge in a way that keeps the expansion intact long enough for sentiment to catch up with the data. Perhaps 2026 will be even better than 2025, as attention shifts from markets and macroeconomics toward things that money can’t buy.

Why 70-plus species of sharks and rays needed new international trade limit protections

The world’s oceans are home to an exquisite variety of sharks and rays, from the largest fishes in the sea – the majestic whale shark and manta rays – to the luminescent but rarely seen deep-water lantern shark and guitarfishes.

The oceans were once teeming with these extraordinary and ancient species, which evolved close to half a billion years ago. However, the past half-century has posed one of the greatest tests yet to their survival. Overfishing, habitat loss and international trade have cut their numbers, putting many species on a path toward extinction within our lifetimes.

Scientists estimate that 100 million (yes, million) sharks and rays are killed each year for food, liver oil and other trade.

The volume of loss is devastatingly unsustainable. Overfishing has sent oceanic shark and ray populations plummeting by about 70% globally since the 1970s.

That’s why countries around the world agreed in December 2025 to add more than 70 shark and ray species to an international wildlife trade treaty’s list for full or partial protection.

It’s an important move that, as a biologist who studies sharks and rays, I believe is long overdue.

Humans put shark species at risk of extinction

Sharks have had a rough ride since the 1970s, when overfishing, habitat loss and international trade in fins, oil and other body parts of these enigmatic sea dwellers began to affect their sensitive populations. The 1975 movie “Jaws” and its portrayal of a great white shark as a mindless killing machine didn’t help people’s perceptions.

One reason shark populations are so vulnerable to overfishing, and less capable of recovering, is the late timing of their sexual maturity and their low numbers of offspring. If sharks and rays don’t survive long enough, the species can’t reproduce enough new members to remain stable.

Losing these species is a global problem because they are vital for a healthy ocean, in large part because they help keep their prey in check.

The bowmouth guitarfish, shown here at the Shedd Aquarium in Chicago, is considered critically endangered.

Endangered and threatened species listings, such as the International Union for Conservation of Nature’s Red List, can help draw attention to sharks and rays that are at risk. But because their populations span international borders, with migratory routes around the globe, sharks and rays need international protection, not just local efforts.

That’s why the international trade agreements set out by the Convention of International Trade in Endangered Species, or CITES, are vital. The convention attempts to create global restrictions that prevent trade of protected species to give them a chance to survive.

New protections for sharks and rays

In early December 2025, the CITES Conference of the Parties, made up of representatives from 184 countries, voted to initiate or expand protection against trade for many species. The votes included adding more than 70 shark and ray species to the CITES lists for full or restricted protection.

The newly listed or upgraded species include some of the most charismatic shark and ray species.

The whale shark, one of only three filter-feeding sharks and the largest fish in the ocean, and the manta and devil rays have joined the list that offers the strictest restrictions on trade, called Appendix I. Whale sharks are at risk from overfishing as well as being struck by ships. Because they feed at the surface, chasing zooplankton blooms, these ocean giants can be hit by ships, especially now that these animals are considered a tourism must-see.

Whale sharks now join this most restrictive list with more well-known, cuddlier mammals such as the giant panda and the blue whale, and they will receive the same international trade protections.

The member countries of CITES agree to the terms of the treaty, so they are legally bound to implement its directives to suspend trade. For the tightest restrictions, under Appendix I, import and export permits are required and allowed only in exceptional circumstances. Appendix II species, which aren’t yet threatened but could become threatened without protections, require export permits. However, the treaty terms are essentially a framework for each member government to then implement legislation under national laws.

Another shark joining the Appendix I list is the oceanic whitetip shark, an elegant, long-finned ocean roamer that has been fished to near extinction. Populations of this once common oceanic shark are down 80% to 95% in the Pacific since the mid-1990s, mostly due to the increase in commercial fishing.

Previously the only sharks or rays listed on Appendix I were sawfish, a group of rays with a long, sawlike projection surrounded by daggerlike teeth. They were already listed as critically endangered by the IUCN’s Red List, which assesses the status of threatened and endangered species, but it was up to governments to propose protections through CITES.

Other sharks gaining partial protections for the first time include deep-sea gulper sharks, which have been prized for their liver oil used for cosmetics. Gulper shark populations have been decimated by unsustainable fishing practices. They will now be protected under Appendix II.

Appendix II listings, while not as strong as Appendix I, can help populations recover. Great white shark populations, for example, have recovered since the 1990s around the U.S. after being added to the Appendix II list in 2005, though other populations in the northwest Atlantic and South Pacific are still considered locally endangered.

Tope and smooth-hound sharks were also added to the Appendix II list in 2025 for protection from the trade of their meat and fins.

Several species of guitarfishes and wedgefishes, odd-shaped rays that look like they have a mix of shark and ray features and have been harmed by local and commercial fishing, finning and trade, were assigned a CITES “zero-quota” designation to temporarily curtail all trade in their species until their populations recover.

These global protections raise awareness of species, prevent trade and overexploitation and can help prevent species from going extinct.

Drawing attention to rarely seen species

Globally, there are about 550 species of shark today and around 600 species of rays (or batoids), the flat-bodied shark relatives.

Many of these species suffer from their anonymity: Most people are unfamiliar with them, and efforts to protect these more obscure, less cuddly ocean inhabitants struggle to draw attention.

So, how do we convince people to care enough to help protect animals they do not know exist? And can we implement global protections when most shark-human interactions are geographically limited and often support livelihoods of local communities?

Increasing people’s awareness of ocean species at risk, including sharing knowledge about why their numbers are falling and the vital roles they play in their ecosystem, can help.

The new protections for sharks and rays under CITES also offer hope that more global regulations protecting these and other shark and rays species will follow.

Deepfakes leveled up in 2025 – here’s what’s coming next

Source: The Conversation – USA – By Siwei Lyu, Professor of Computer Science and Engineering; Director, UB Media Forensic Lab, University at Buffalo

AI image and video generators now produce fully lifelike content. AI-generated image by Siwei Lyu using Google Gemini 3

Over the course of 2025, deepfakes improved dramatically. AI-generated faces, voices and full-body performances that mimic real people increased in quality far beyond what even many experts expected would be the case just a few years ago. They were also increasingly used to deceive people.

For many everyday scenarios — especially low-resolution video calls and media shared on social media platforms — their realism is now high enough to reliably fool nonexpert viewers. In practical terms, synthetic media have become indistinguishable from authentic recordings for ordinary people and, in some cases, even for institutions.

And this surge is not limited to quality. The volume of deepfakes has grown explosively: Cybersecurity firm DeepStrike estimates an increase from roughly 500,000 online deepfakes in 2023 to about 8 million in 2025, with annual growth nearing 900%.

I’m a computer scientist who researches deepfakes and other synthetic media. From my vantage point, I see that the situation is likely to get worse in 2026 as deepfakes become synthetic performers capable of reacting to people in real time.

Just about anyone can now make a deepfake video.

Dramatic improvements

Several technical shifts underlie this dramatic escalation. First, video realism made a significant leap thanks to video generation models designed specifically to maintain temporal consistency. These models produce videos that have coherent motion, consistent identities of the people portrayed, and content that makes sense from one frame to the next. The models disentangle the information related to representing a person’s identity from the information about motion so that the same motion can be mapped to different identities, or the same identity can have multiple types of motions.

These models produce stable, coherent faces without the flicker, warping or structural distortions around the eyes and jawline that once served as reliable forensic evidence of deepfakes.

Second, voice cloning has crossed what I would call the “indistinguishable threshold.” A few seconds of audio now suffice to generate a convincing clone – complete with natural intonation, rhythm, emphasis, emotion, pauses and breathing noise. This capability is already fueling large-scale fraud. Some major retailers report receiving over 1,000 AI-generated scam calls per day. The perceptual tells that once gave away synthetic voices have largely disappeared.

Third, consumer tools have pushed the technical barrier almost to zero. Upgrades from OpenAI’s Sora 2 and Google’s Veo 3 and a wave of startups mean that anyone can describe an idea, let a large language model such as OpenAI’s ChatGPT or Google’s Gemini draft a script, and generate polished audio-visual media in minutes. AI agents can automate the entire process. The capacity to generate coherent, storyline-driven deepfakes at a large scale has effectively been democratized.

This combination of surging quantity and personas that are nearly indistinguishable from real humans creates serious challenges for detecting deepfakes, especially in a media environment where people’s attention is fragmented and content moves faster than it can be verified. There has already been real-world harm – from misinformation to targeted harassment and financial scams – enabled by deepfakes that spread before people have a chance to realize what’s happening.

AI researcher Hany Farid explains how deepfakes work and how good they’re getting.

The future is real time

Looking forward, the trajectory for next year is clear: Deepfakes are moving toward real-time synthesis that can produce videos that closely resemble the nuances of a human’s appearance, making it easier for them to evade detection systems. The frontier is shifting from static visual realism to temporal and behavioral coherence: models that generate live or near-live content rather than pre-rendered clips.

Identity modeling is converging into unified systems that capture not just how a person looks, but how they move, sound and speak across contexts. The result goes beyond “this resembles person X,” to “this behaves like person X over time.” I expect entire video-call participants to be synthesized in real time; interactive AI-driven actors whose faces, voices and mannerisms adapt instantly to a prompt; and scammers deploying responsive avatars rather than fixed videos.

As these capabilities mature, the perceptual gap between synthetic and authentic human media will continue to narrow. The meaningful line of defense will shift away from human judgment. Instead, it will depend on infrastructure-level protections. These include secure provenance such as media signed cryptographically, and AI content tools that use the Coalition for Content Provenance and Authenticity specifications. It will also depend on multimodal forensic tools such as my lab’s Deepfake-o-Meter.

Simply looking harder at pixels will no longer be adequate.

New materials, old physics – the science behind how your winter jacket keeps you warm

As the weather grows cold this winter, you may be one of the many Americans pulling their winter jackets out of the closet. Not only can this extra layer keep you warm on a chilly day, but modern winter jackets are also a testament to centuries-old physics and cutting-edge materials science.

Winter jackets keep you warm by managing heat through the three classical modes of heat transfer – conduction, convection and radiation – all while remaining breathable so sweat can escape.

In a fireplace, heat transfer occurs by all three methods: conduction, convection and radiation. Radiation is responsible for most of the heat transferred into the room. Heat transfer also occurs through conduction into the room’s floor, but at a much slower rate. Heat transfer by convection also occurs through cold air entering the room around windows and hot air leaving the room by rising up the chimney.

The physics has been around for centuries, yet modern material innovations represent a leap forward that let those principles shine.

Old science with a new glow

Physicists like us who study heat transfer sometimes see thermal science as “settled.” Isaac Newton first described convective cooling, the heat loss driven by fluid motion that sweeps thermal energy away from a surface, in the early 18th century. Joseph Fourier’s 1822 analytical theory of heat then put conduction – the transfer of thermal energy through direct physical contact – on mathematical footing.

Late-19th-century work by Josef Stefan and Ludwig Boltzmann, followed by the work of Max Planck at the dawn of the 20th century, made thermal radiation – the transfer of heat through electromagnetic waves – a pillar of modern physics.

All these principles inform modern materials design. Yet what feels new today are not the equations but the textiles. Over the last two decades, engineers have developed extremely thin synthetic fibers that trap heat more efficiently and treatments that make natural down repel water instead of soaking it up. They’ve designed breathable membranes full of tiny pores that let sweat escape, thin reflective layers that bounce your body heat back toward you, coatings that store and release heat as the temperature changes, and ultralight materials.

Together, these innovations give designers far more control over warmth, breathability and comfort than ever before. That’s why jackets now feel warmer, lighter and drier than anything Newton or Fourier could have imagined.

Trap still air, slow the leak

Conduction is the direct flow of heat from your warm body into your colder surroundings. In winter, all that heat escaping your body makes you feel cold. Insulation fights conduction by trapping air in a web of tiny pockets, slowing the heat’s escape. It keeps the air still and lengthens the path heat must take to get out.

High-loft down makes up the expansive, fluffy clusters of feathers that create the volume inside a puffer jacket. Combined with modern synthetic fibers, the down immobilizes warm air and slows its escape. New types of fabrics infused with highly porous, ultralight materials called aerogels pack even more insulation into surprisingly slim layers.

Tame the wind, protect the boundary layer

A good winter jacket also needs to withstand wind, which can strip away the thin boundary layer of warm air that naturally forms around you. A jacket with a good outer shell blocks the wind’s pumping action with tightly woven fabric that keeps heat in. Some jackets also have an outer layer of lamination that keeps water and cold air out, and a woven pattern that seals any paths heat might leak through around the cuffs, hems, flaps and collars.

The outer membrane layer on many jacket shells is both waterproof and breathable. It stops rain and snow from getting in, and it also lets your sweat escape as water vapor. This feature is key because insulation, such as down, stops working if it gets wet. It loses its fluff and can’t trap air, meaning you cool quickly.

How modern jackets manage heat: Left, a typical insulated shell; right, layers that trap air, block wind, and reflect infrared heat without adding bulk.
Wan Xiong and Longji Cui

These shells also block wind, which protects the bubble of warm air your body creates. By stopping wind and water, the shell creates a calm, dry space for the insulation to do its job and keep you warm.

New tricks to reflect infrared heat

Even in still air, your body sheds heat by emitting invisible waves of heat energy. Modern jackets address this by using new types of cloth and technology that make the jacket’s inner surface reflect your body’s heat back toward you. This type of surface has a subtle space blanket effect that adds noticeable warmth without adding any bulk.

However, how jacket manufacturers apply that reflective material matters. Coating the entire material in metallic film would reflect lots of heat, but it wouldn’t allow sweat to escape, and you might overheat.

Some liners use a micro-dot pattern: The reflective dots bounce heat back while the gaps between them keep the material breathable and allow sweat to escape.

Another approach moves this technology to the outside of the garment. Some designs add a pattern of reflective material to the outer shell to keep heat from radiating out into the cold air.

When those exterior dots are a dark color, they can also absorb a touch of warmth from the sun. This effect is similar to window coatings that keep heat inside while taking advantage of sunlight to add more heat.

Warmth only matters if you stay dry. Sweat that can’t escape wets a jacket’s layer of insulation and accelerates heat loss. That’s why the best winter systems combine moisture-wicking inner fabrics with venting options and membranes whose pores let water vapor escape while keeping liquid water out.

What’s coming

Describing where heat travels throughout textiles remains challenging because, unlike light or electricity, heat diffuses through nearly everything. But new types of unique materials and surfaces with ultra-fine patterns are allowing scientists to better control how heat travels throughout textiles.

Managing warmth in clothing is part of a broader heat-management challenge in engineering that spans microchips, data centers, spacecraft and life-support systems. There’s still no universal winter jacket for all conditions; most garments are passive, meaning they don’t adapt to their environment. We dress for the day we think we’ll face.

But some engineering researchers are working on environmentally adaptive textiles. Imagine fabrics that open microscopic vents as the humidity rises, then close them again in dry, bitter air. Picture linings that reflect more heat under blazing sun and less in the dark. Or loft that puffs up when you’re outside in the cold and relaxes when you step indoors. It’s like a science fiction costume made practical: Clothing that senses, decides and subtly reconfigures itself without you ever touching a zipper.

Today’s jackets don’t need a new law of thermodynamics to work – they couple basic physics with the use of precisely engineered materials and thermal fabrics specifically made to keep heat locked in. That marriage is why today’s winter wear feels like a leap forward.

Who thinks Republicans will suffer in the 2026 midterms? Republican members of Congress

The midterm elections for Congress won’t take place until November, but already a record number of members have declared their intention not to run – a total of 43 in the House, plus 10 senators. Perhaps the most high-profile person to depart, Republican Rep. Marjorie Taylor Greene of Georgia, announced her intention in November not just to retire but to resign from Congress entirely on Jan. 5 – a full year before her term was set to expire.

There are political dynamics that explain this rush to the exits, including frustrations with gridlock and President Donald Trump’s lackluster approval ratings, which could hurt Republicans at the ballot box.

Rather than get swept away by a prospective “blue wave” favoring Democrats – or possibly daunted by the monumental effort it would take to survive – many Republicans have decided to fold up the beach chair and head home before the wave crashes.

As of now, two dozen Republican House members have either resigned from the House or announced their intent to not run for reelection in 2026. With only two exceptions – Republicans in 2018 and 2020 – this is more departures from either party at this point in the election calendar than any other cycle over the past 20 years.

There is also growing concern within the House Republican caucus that Greene’s announcement is a canary in the coal mine and that multiple resignations will follow.

As a political scientist who studies Congress and politicians’ reelection strategies, I’m not surprised to see many House members leaving ahead of what’s shaping up to be a difficult midterm for the GOP. Still, the sheer numbers of people not running tells us something about broader dissatisfaction with Washington.

Why do members leave Congress?

Many planned departures are true retirements involving older and more experienced members.

For example, 78-year-old Democratic congressman Jerry Nadler is retiring after 34 years, following mounting pressure from upstart challengers and a growing consensus among Democrats that it’s time for older politicians to step aside. Nancy Pelosi, the former speaker who will turn 86 in March, is also retiring.

Sometimes, members of Congress depart for the same reasons other workers might leave any job. Like many Americans, members of Congress might find something more attractive elsewhere. Retiring members are attractive hires for lobbying firms and corporations, thanks to their insider knowledge and connections within the institution. These firms usually offer much higher salaries than members are used to in Congress, which may explain why more than half of all living former members are lobbyists of some kind.

Other members remain ambitious for elective office and decide to use their position in Congress as a springboard for another position. Members of the House regularly retire to run for a Senate seat, such as, in this cycle, Democratic Rep. Haley Stevens of Michigan. Others run for executive offices, including governor, such as Republican Rep. Nancy Mace of South Carolina.

But some are leaving Congress due to growing frustration with the job and an inability to get things done. Specifically, many retiring members cite growing dysfunction within their own party, or in Congress as a whole, as the reason they’re moving on.

In a statement announcing his departure in June, Sen. Thom Tillis, R-N.C., mused that “between spending another six years navigating the political theater and partisan gridlock in Washington or spending that time with my family,” it was “not a hard choice” to leave the Senate.

What’s unique about 2026?

In addition, there are a few other factors that can help explain why so many Republicans in particular are heading for the exits leading up to 2026.

The shifting of boundaries that has come with the mid-decade redistricting process in several states this year has scrambled members’ priorities. Unfamiliar districts can drive incumbents to early retirement by severing their connection with well-established constituencies.

In Texas, six Republicans and three Democrats – nearly a quarter of the state’s entire House delegation – are either retiring or running for other offices, due in part to that state’s new gerrymander for 2026.

All decisions about retirement and reelection are sifted through the filter of electoral and partisan considerations. A phenomenon called “thermostatic politics” predicts that parties currently in power, particularly in the White House, tend to face a backlash from voters in the following election. In other words, the president’s party nearly always loses seats in midterms.

In 2006 and 2018, for example, Republican members of Congress were weighed down by the reputations of unpopular Republican Presidents George W. Bush and Trump. Republicans had arguably even greater success in midterm elections during Barack Obama’s presidency.

Currently, 2026 looks like it will present a poor national environment for Republicans. Trump remains highly unpopular, according to polls, and Democrats are opening up a consistent lead in the “generic ballot” question, which asks respondents which party they intend to support in the 2026 midterms without reference to individual candidates.

Democrats have already been overperforming in special elections, as well as the general election in November in states such as New Jersey and Virginia, which held elections for governor. Democrats are on average running 13 points ahead of Kamala Harris’ performance in the 2024 election.

As a result, even Republicans in districts thought to be safe for their party may see themselves in enough potential danger to abandon the fight in advance.

Retirement vs. resignation

One final, unique aspect of this election cycle with major consequences is not an electoral but an institutional one.

House conservatives are quietly revolting against Speaker Mike Johnson’s leadership style. That members may be frustrated enough not just to retire but resign in advance, leaving their seats temporarily vacant, is a notable sign of dysfunction in the U.S. House.

This also could have a major impact on policy, given how slim the Republicans’ majority in the lower chamber is already. Whatever the outcome of the midterms in November, these departures clearly matter in Washington and offer important signals about the chaos in Congress.

Resolve to network at your employer’s next ‘offsite’ – research shows these retreats actually help forge new connections

What do you do when an announcement about an “offsite” hits your work inbox? Chances are you might sigh and begrudgingly add the event to your calendar.

These events, also called retreats, bring colleagues together for a mix of structured activities and free time – freeing them from their regular work obligations. For one or two days, employees take a mandatory break from their normal routines at work and at home. Participants spend a lot of that time making small talk with colleagues, as well as engaging in structured interactions that may include awkward icebreakers.

Although networking is one of these events’ main purposes, some people find that networking for the purpose of meeting professional goals can feel transactional, uncomfortable or even dirty. Unsure about whether it will be worth the time and effort, you might ask: What’s in it for me?

We are management professors who study how professional networks help information and resources move across organizations and create opportunities. Our research findings suggest participating in an offsite could be well worth the time and hassle.

And it might quietly reshape your working relationships in unexpected ways.

Taking time and costing money

While these gatherings have become relatively common, we were surprised to learn how little research there is on whether they work. In particular, few scholars have dug into their effectiveness in helping people forge new connections.

Offsites can help with strategic planning, team development and goal setting. They’re often held once or twice a year. The timing varies from one employer to the next. But the period from December through March is becoming more popular.

They tend to bring people together who rarely interact through their work – particularly at large employers with offices spread across the country or even the world, and in organizations with remote-first work arrangements.

Retreats help people get better acquainted in many informal ways, whether it’s sharing meals, exchanging ideas or chatting in hallways. Those interactions and the more structured ones, such as brainstorming exercises conducted in previously assigned groups, make it easier to connect with colleagues.

After years of remote work when people mainly gathered over Zoom, employers continue to look for ways to rebuild connections and to address a surge in disengagement.

These retreats for professionals have apparently become more popular following the COVID-19 pandemic, as part of the larger rebound in business-related travel. A survey of 2,000 full-time employees from a range of industries found that the percentage of companies hosting no offsites at all fell to 4% in 2024, from 16% in 2019.

Further, many companies are allocating larger budgets for offsites and budgeting more time during off-site retreats for social purposes, the same survey found.

Off-site retreats require planning to make sure there’s time for colleagues to make new connections.

When we spoke with managers from several large firms about their off-site practices, we were surprised that they simply assumed collaboration was an inevitable outcome.

To test whether that was true, we studied the working relationships of more than 700 partners in a large U.S. law firm, which we agreed not to name to access its data. Over eight years, from 2005 to 2012, these partners attended – or skipped – the firm’s annual retreats.

We tracked the partners’ attendance and their collaborative work for the firm’s clients before and after the offsites. Because lawyers at this firm – and elsewhere – record their work in 6-minute increments, it was possible to analyze billing records for the partners’ collaboration on client projects.

The results of this mapping exercise surprised us. And they may change your feelings about whether retreats are worth your time and energy.

Helping partners get noticed

We found that after participating in an offsite, partners were more likely to reach out to other partners whom they had not worked with previously.

To our surprise, we found that even workers who didn’t attend an offsite acted more collaboratively afterward. Having received the message that collaboration is important to the firm, they made up for missing out by finding other ways to start collaborating with more colleagues.

But building a successful career also depends on something harder to control than whether you reach out to new colleagues and clients: You need your colleagues to think of you when opportunities arise. And that likelihood can increase when you participate in offsites.

Getting 24% more requests to collaborate

We found an increase in newly formed connections across the law firm after these events. New collaborations on billable work increased, generating more revenue for the firm. And the targets of these new collaborations tended to be the people who took part in the offsite.

The partners who attended the offsite became more visible and had 24% more new requests to collaborate on work for a client in the two months following the retreat than those who did not. Importantly, these relationships were not superficial. Almost 17% of these new working relationships continued over the next two years.

While we analyzed only the relationships that formed shortly after the offsite, it is likely that colleagues remember those they meet at these events. The people who attend them continue to reap network-based benefits beyond what we found in the data.

We also found that offsites helped attorneys forge connections with lawyers in the firm’s other practice groups more than with those on their own team.

Overall, lawyers who went to an offsite made more new connections – about one per month – after an offsite than the ones who didn’t go.

Bridging silos at work

In the course of day-to-day work, people tend to interact most with the colleagues they already know.

This pattern seems to be even stronger in remote work. Offsites helped to break that pattern by giving professionals opportunities to engage with colleagues they don’t know. Sometimes, they end up eager to collaborate with people they meet this way.

These more distant connections can help people obtain diverse information, resources and perspectives and create opportunities to productively brainstorm.

When you work for a big employer, it can be hard to meet colleagues on other teams. Offsites may provide a significant opportunity to build networks and stand out among peers.

While offsites may never be your favorite way to spend a few days, our research shows that they can serve an important function for employers and employees alike.
