Scientists studying ancient microfossils from Brazil have discovered that structures once believed to be traces left behind by tiny animals were actually formed by communities of microscopic bacteria and algae. The findings challenge previous ideas about when small animals first appeared on Earth and suggest oxygen levels in ancient oceans may still have been too low to support certain forms of animal life around 540 million years ago.

The research focused on fossils found in the Brazilian state of Mato Grosso do Sul and was published in the journal Gondwana Research. Earlier studies had interpreted the marks as evidence of wormlike creatures or other tiny marine animals moving through seafloor sediment during the Ediacaran period, which came just before the Cambrian explosion.

For decades, scientists searching for life beyond Earth have focused on one central challenge: identifying the right molecules to look for on distant planets and moons.

But new research published in Nature Astronomy suggests the answer may lie not in the molecules themselves, but in the hidden patterns that connect them.

“We’re showing that life does not only produce molecules,” said Fabian Klenner, UC Riverside assistant professor of planetary sciences and co-author of the study. “Life also produces an organizational principle that we can see by applying statistics.”

A new report from the US National Partnership for Women & Families says women may face disproportionate disruption from artificial intelligence in the workforce. The study found that while women make up about 47 percent of the US workforce, they account for 83 percent of workers across 15 occupations identified as having the highest exposure to AI.Those roles include secretaries, receptionists, and office clerks, among others. According to the report, around 6 million women work in these positions.

Researchers said workers in these jobs may face greater challenges adapting to AI-related workplace changes due to lower access to resources and reduced flexibility in transitioning to other roles. The report also looked at sectors where women are more heavily represented but less likely to face full automation, including nursing, childcare, and home health care, in addition to others.

While these jobs typically require direct human interaction and physical presence, the study said AI could still affect workers in those fields through monitoring and workplace management systems: “These management systems, sometimes described as bossware, can be difficult for workers to understand or challenge, and may worsen job quality even where jobs are not eliminated,” the report said.

Anthropic (ANTH.PVT) is expanding its presence in the legal software market as it continues to grow its enterprise footprint.

The latest offerings include integration with platforms law firms already use, such as Box (BOX) and Thomson Reuters (TRI), plugins designed for specific tasks and roles such as corporate counsel, regulatory counsel, and law students, and integration with Microsoft (MSFT) 365.

The launch comes just a week after Anthropic debuted its Claude for Financial Services, which includes 10 customizable AI agents for financial users, the ability to use Claude’s financial capabilities across Microsoft 365, and the option to connect Claude to more applications.

It also comes as the software industry continues to deal with the fallout from the initial debut of Anthropic’s Claude Cowork, which has hammered software stocks over fears that the AI startup will steal market share from existing enterprise platforms.

Anthropic’s new legal products could further raise concerns about the future of legacy enterprise services.

The company’s latest products feature 20 model context protocol (MCP) connectors, which allow Claude to connect to existing pools of data and tools in apps. That includes the ability to use Claude with programs such as DocuSign (DOCU), Ironclad, Datasite, and other legal software.

“Artificial intelligence is not just for computer scientists anymore; it’s going to permeate every aspect of our lives and influence every business,” says MIT President Sally Kornbluth.

The world is reaching an inflection point with artificial intelligence: over half of U.S. adults use generative AI — with 12 percent using it daily at work — and 88 percent of global organizations have integrated AI into at least one core function, up from 78 percent in 2024. AI knowledge is no longer optional for career growth, organizational leadership, and life. Yet, a growing information gap exists between those with the capabilities to leverage AI’s potential and those trying to keep pace.

The need for accessible, practical AI education has never been greater. To meet this moment, MIT Open Learning is launching Universal AI, an online, self-paced, modular program that takes a learner from AI novice to authority, starting with core fundamentals and building to real-world, industry-specific applications.

“We identified a need for an AI learning experience that is universal in breadth and accessibility — one that bridges the gap between deeply technical and surface level introductions to the latest AI tools, and that is designed for a non-technical, global audience,” says Dimitris Bertsimas, vice provost for open learning.

A cluster of high-profile political attacks in the U.S. spotlight the nation’s extreme divisions—but they don’t necessarily signal a broader uptick in politically inspired brutality, experts say.

Politicians, pundits and ordinary Americans are increasingly worried about political violence. The latest round of concern was sparked on April 25, when a 31-year-old man stormed the Washington Hilton hotel in Washington, D.C., during the annual White House Correspondents’ Association dinner, where President Donald Trump was in attendance. Secret Service agents arrested the armed man before he could get to the ballroom where the event was being held. He has since been charged with attempted assassination of the president—which would represent the third serious attempt on Trump’s life since 2024. The man has pled not guilty to this and related charges.

For years, the evolution of flight seemed fairly straightforward. Dinosaurs developed feathers, with some learning to glide, and eventually, birds appeared and mastered the skies. Now, a strange fossil from China is making scientists rethink that neat timeline. The feathered dinosaur Anchiornis huxleyi reportedly had four wings, colourful feathers, and a surprisingly messy moulting pattern that suggests it may not have been capable of proper flight at all.Experts say it hints that some dinosaurs could have evolved flight-related features and later lost the ability entirely. A bit like modern ostriches or penguins. The fossil has even been described as the first real “technicolour” dinosaur discovery because traces of its original feather patterns were preserved in remarkable detail.

Chinese researchers have made a significant advancement in circular resource recovery by creating a new way to turn nitrate-laden wastewater into valuable ammonia for fertilisers. They used artificial intelligence to find a super-effective dual-atom catalyst, which led them to a process that tackles two major global issues: water pollution and the heavy energy use of traditional industrial ammonia production. Their findings, published in the Journal of the American Chemical Society, show that this method achieves almost three times the conversion efficiency of earlier technologies. By converting runoff from farms and factories, this approach provides an eco-friendly solution to lessen environmental ‘dead zones’ and cuts down on the agricultural sector’s dependence on energy-heavy chemical methods.

An experiment at the University of Rochester shows the long-life genes of moles could be transplanted to mice, producing mice that live longer than average mice.

Rochester University’s Biology and Medicine Professor Vera Gorbunova explained, “Our study provides a proof of principle that unique longevity mechanisms that evolved in long-lived mammalian species can be exported to improve the lifespans of other mammals.”

AI agents choose tools from shared registries by matching natural-language descriptions. But no human is verifying whether those descriptions are true.

I discovered this gap when I filed Issue #141 in the CoSAI secure-ai-tooling repository. I assumed it would be treated as a single risk entry. The repository maintainer saw it differently and split my submission into two separate issues: One covering selection-time threats (tool impersonation, metadata manipulation); the other covering execution-time threats (behavioral drift, runtime contract violation).

That confirmed tool registry poisoning is not one vulnerability. It represents multiple vulnerabilities at every stage of the tool’s life cycle.

There’s an immediate tendency to apply the defenses we already have. Over the past 10 years, we’ve built software supply chain controls, including code signing, software bill of materials (SBOMs), supply-chain levels for software Artifacts (SLSA) provenance, and Sigstore. Applying these defense-in-depth techniques to agent tool registries is the next logical step. That instinct is right in spirit, but insufficient in practice.

A massive system of ocean currents in the Atlantic that plays a key role in regulating Earth’s climate has been weakening for almost 20 years, according to a new study. Scientists say the slowdown stretches across a large section of the Atlantic Ocean and could eventually alter weather patterns around the world.

The research was led by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science. Their findings provide some of the strongest direct observational evidence so far that the Atlantic Meridional Overturning Circulation (AMOC) is losing strength. The results could help researchers improve climate models and better understand how ongoing climate change may affect the future.

“A weaker AMOC can shift weather patterns, potentially leading to more extreme storms, changes in rainfall, or colder winters in some regions,” said Shane Elipot, a senior author of the study and physical oceanographer at the Rosenstiel School. “It can also influence sea-level rise along coastlines, affecting communities and infrastructure.”

Most of humanity has a great propensity to think in the short-term, but generally, long-term considerations — air pollution, deforestation and emissions, for example — just aren’t our thing.

That’s partly why scientists are deeply concerned about a recent SpaceX proposal to launch one million satellites — data centres — into orbit around Earth.

Their concerns range from losing the natural night sky, to losing access to space, to the environmental impact on our atmosphere.

At the moment, there are roughly 16,000 satellites orbiting Earth, 14,000 of which are active. SpaceX is responsible for more than 8,000 of them.

Scientists may have discovered a powerful new link between the gut microbiome, aging, and liver cancer. New research presented at Digestive Disease Week® (DDW) 2026 suggests that restoring gut bacteria to a more youthful state could help protect the liver, reduce age related damage, and potentially lower cancer risk.

The findings come from a mouse study focused on the microbiome, the vast community of bacteria and other microbes living in the digestive system. Researchers found that giving older mice back their own younger gut microbes produced striking effects throughout the body, especially in the liver.

Dante’s famous 14th century epic poem, “Inferno,” which is the first part of the Italian writer’s “Divine Comedy,” represents the first time a giant impact of a massive object falling from the heavens was envisaged, according to an expert in the specialized field of geomythology.

In the poem, the massive object in question is the Devil himself, Lucifer, who fell onto the Earth after being expelled from heaven. Yet, according to Timothy Burberry of Marshall University in West Virginia , this fall and subsequent impact is described by Dante in very similar terms to an asteroid impact.

Burberry is a professor of English and an expert in geomythology, a field which involves searching old folk tales, myths and stories for evidence of real geological events. Written between 1308 and 1321, Dante’s “Inferno” depicts the main character — Dante himself — being guided through Hell by the spirit of the ancient Roman poet Virgil.

In what is considered one of the greatest works in the history of European literature, Dante and Virgil travel to the Underworld, where they are taken across the River Styx to Hell by the ferryman Charon — in fact, two of Pluto‘s moons, Charon and Styx, are named after these details.

Neuroscientists have identified a measurable brain difference between people with psychopathic traits and those with few or none. In a study published in the Journal of Psychiatric Research, researchers from Nanyang Technological University, Singapore (NTU Singapore), the University of Pennsylvania, and California State University found that a brain region involved in reward and motivation was larger in individuals with psychopathic traits.

Using magnetic resonance imaging (MRI), the team found that the striatum was about 10 percent larger on average in psychopathic individuals compared with a control group. The striatum sits deep in the forebrain and plays a role in movement planning, decision-making, motivation, reinforcement, and how the brain responds to rewards.
