Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in a coordinated way throughout the body. About a quarter of cell types change in number over time, and many of these shifts differ between males and females. The research also highlights shared genetic âhotspotsâ that could become targets for anti-aging therapies.

The Trump administrationâs rhetoric on the war in Iran tends to be heavy on words like âlethalityâ and âobliteration,â so it was notable that the president seemed almost apologetic on Wednesday, when discussing an Israeli strike on Iranâs South Pars gas field, which prompted Iranian retaliation against natural gas facilities in Qatar and sent global [âŠ] Read more âș

Large language models are running into limits in domains that require an understanding of the physical world â from robotics to autonomous driving to manufacturing. That constraint is pushing investors toward world models, with AMI Labs raising a $1.03 billion seed round shortly after World Labs secured $1 billion.Large language models (LLMs) excel at processing abstract knowledge through next-token prediction, but they fundamentally lack grounding in physical causality. They cannot... Read more âș

After one too many of you threatened to switch to Linux, Microsoft has published a long list of changes it plans to make to Windows 11. In a lengthy blog titled "Our commitment to Windows quality," Pavan Davuluri, the executive vice president of Windows and Devices, said the company has spent a "great deal" of time in recent months reading feedback from users. "What came through was the voice of... Read more âș

Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of Sun-like stars billions of years ago. The journey may have carried the solar system away from the galaxyâs crowded center into a calmer region where life could eventually emerge. Read more âș

Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel. During combustion, the water rapidly vaporizes, triggering micro-explosions that improve fuel mixing and lower combustion temperatures. Studies show this technique can slash nitrogen oxide and soot emissions by more than 60% while sometimes even improving engine efficiency. Because it works in existing engines without redesign, it could provide a quick... Read more âș

Tiny plastic particles may be quietly threatening brain health. New research suggests microplasticsânow widely found in food, water, and even household dustâcould trigger inflammation and damage in the brain through multiple biological pathways. Scientists estimate adults may consume about 250 grams of these particles each year, and some can accumulate in organs including the brain. Read more âș

A newly identified Australian tree has been dubbed the âzombieâ tree because itâs alive but unable to reproduce. Myrtle rust repeatedly kills its young growth, stopping the species from flowering or making seeds. Scientists are scrambling to grow disease-free seedlings in protected locations. Their hope is that a future generation may evolve resistance and bring the species back from the brink. Read more âș

Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin levels, increased nerve cells in the colon, and normalized intestinal movement. The study also found that people with IBS have lower levels of one of these bacteria. The discovery suggests gut microbes could become a powerful new target for treating digestive disorders.

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million regulatory DNA sequences that act like genetic switches, controlling when and how genes are activated. These sequences, known as conserved non-coding sequences (CNSs), were detected using a new computational tool called Conservatory. Read more âș

Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses an LED lamp to create essential carbonâcarbon bonds under mild conditions. This could make drug discovery faster and more environmentally friendly. The breakthrough was uncovered unexpectedly during a failed laboratory experiment. Read more âș

Scientists may have finally solved the mystery of strange plume-like structures hidden deep inside the Greenland ice sheet. New research suggests they form through thermal convectionâslow, swirling motions driven by temperature differences inside the ice. This means the deep ice could be far softer than scientists once believed. Understanding this hidden movement could improve predictions about how Greenlandâs ice sheet behaves in a warming world.

Hair may grow in a completely different way than scientists once believed. Instead of being pushed out from the root, new research shows that moving cells inside the follicle actually pull the hair upward like a microscopic motor. Advanced 3D imaging revealed a spiral movement of cells that generates this force. The finding could change how scientists study hair loss and design future treatments. Read more âș

Researchers have created âSmart Underwear,â a wearable device that measures flatulence by detecting hydrogen produced by gut microbes. Early tests suggest people may pass gas about 32 times a dayâmuch higher than previous estimates. The device gives scientists a new way to track gut microbial activity in everyday life. It will power a new nationwide study called the Human Flatus Atlas to map normal patterns of gas production. Read more âș
