Sponges may be ancient, but their timeline has been murky. New research suggests the earliest sponges were soft and skeleton-free, explaining why their fossils don’t appear until much later. By analyzing hundreds of genes and modeling how skeletons evolved, scientists found that mineralized spicules arose separately in different sponge lineages. The discovery rewrites the story of how the first reef-building animals—and possibly the first animals of all—emerged.

A friend once pulled me aside after a dinner party and told me something that stung: “You’re treating everyone here like interview subjects. You’re gathering data, not connecting.” She was right. I thought I was being engaging, asking questions, showing interest. What I was actually doing was performing a version of conversation that looked like ... Read more Read more ›

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed. This loss has been linked to heart disease, cancer, Alzheimer’s, and shorter lifespans. Researchers suspect Y-less cells may grow faster and disrupt normal body functions. What seemed like a minor genetic quirk could actually be a major driver of age-related disease. Read more ›

I retired four years ago at 62. Everybody told me the first year would be the hardest. They said I would miss the routine, the purpose, the identity. They said I would feel lost without the structure. And they were right about all of that, for about eight months. Then I adjusted. I found a ... Read more Read more ›

A group of former Twitter investors have prevailed at a federal civil trial over Elon Musk's actions amid his $44 billion acquisition of the social platform in 2022. A jury in San Francisco found Friday that tweets made by Musk about fake accounts on the platform had defrauded investors in the company. The jury sided with Musk on other allegations in the case. It's not yet clear how much Musk... Read more ›

A newly identified Australian tree has been dubbed the “zombie” tree because it’s 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 ›

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 ›

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 carbon–carbon 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 ›

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 convection—slow, 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 Greenland’s 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 ›

Researchers have created “Smart Underwear,” a wearable device that measures flatulence by detecting hydrogen produced by gut microbes. Early tests suggest people may pass gas about 32 times a day—much 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 ›

Spiders and insects may not be fan favorites, but they are vital to the health of ecosystems—and scientists barely know how they’re doing. Researchers found that nearly 90% of North America’s insect and arachnid species have no conservation status, leaving their fate largely unknown. Even more striking, most states don’t protect a single arachnid species. The study warns that these overlooked creatures are essential to planetary health and urgently need... Read more ›

NASA’s Curiosity rover is investigating strange spiderweb-like ridges on Mars that may reveal a hidden chapter of the planet’s watery history. These “boxwork” formations likely formed when groundwater flowed through cracks in the rock, leaving minerals that hardened into ridges while surrounding material eroded away. New chemical analyses of drilled rock samples show minerals linked to water activity. Read more ›

Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a frozen desert. NASA’s twin-spacecraft ESCAPADE mission aims to watch this process in action by measuring how the solar wind interacts with Mars’ fragile magnetic environment. The findings could reveal how Mars lost its habitability—and help... Read more ›
