Scientists replayed evolution and found a surprise Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher fitness, while others slow or

Earth’s worst extinction was followed by a shockingly fast ocean comeback A spectacular fossil trove on the Arctic island of Spitsbergen shows that marine life made a stunning comeback after Earth’s greatest extinction. Tens of thousands of fossils reveal fully aquatic reptiles

Stay ready for outages with Powerwall and Storm Watch during extreme weather.

Time runs faster on Mars and scientists just proved it Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster—and fluctuate over the Martian year. These

Scientists stunned by a massive hydrothermal field off Greece Scientists have uncovered an extensive underwater vent system near Milos, Greece, hidden along active fault lines beneath the seafloor. These geological fractures act as pathways for hot, gas-rich fluids to escape,

Why your vitamin D supplements might not be working A new randomized trial from Vanderbilt-Ingram Cancer Center reveals that magnesium may be the missing key to keeping vitamin D levels in balance. The study found that magnesium raised vitamin D in people who were deficient

Some whales sing so loud their songs can travel halfway across the planet underwater.

From “I’m just tired” to “I’m fine, really”—here’s what we’re actually saying when we’re emotionally unravelling with a smile on our face (and a trolley full of coping mechanisms). https://t.co/JYOoRGBBPS

MIT scientists find a way to rejuvenate the immune system as we age As the immune system weakens with age, scientists have found a way to restore some of its lost strength. By delivering mRNA to the liver, they created a temporary source of immune-boosting signals that normally

Scientists found a dangerous feedback loop accelerating Arctic warming The Arctic is changing rapidly, and scientists have uncovered a powerful mix of natural and human-driven processes fueling that change. Cracks in sea ice release heat and pollutants that form clouds and speed

The brain has a hidden language and scientists just found it Researchers have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons process incoming

A gold catalyst just broke a decade old green chemistry record A new catalyst design could transform how acetaldehyde is made from renewable bioethanol. Researchers found that a carefully balanced mix of gold, manganese, and copper creates a powerful synergy that boosts

MIT just made aluminum 5x stronger with 3D printing MIT researchers have designed a printable aluminum alloy that’s five times stronger than cast aluminum and holds up at extreme temperatures. Machine learning helped them zero in on the ideal recipe in a fraction of the time

Mars dust storms are crackling with electricity Mars isn’t just dusty—it crackles with electricity. Scientists discovered that dust devils can generate tiny electric sparks, captured for the first time by Perseverance’s microphone. These static discharges may rapidly destroy

This hidden flaw has been breaking EV batteries A major breakthrough in battery science reveals why promising single-crystal lithium-ion batteries haven’t lived up to expectations. Researchers found that these batteries crack due to uneven internal reactions, not the

Ancient wolves could only have reached this island by boat Scientists have uncovered ancient wolf remains on a small Baltic island where wolves could only have been brought by humans. These animals weren’t dogs, but true wolves that ate the same marine food as the people living

Social media turned us all into tiny public figures—performing, posting, and building personas. Here’s how to navigate it without losing yourself. https://t.co/Xnl4pcQpCe

ADHD drugs don’t work the way we thought ADHD stimulants appear to work less by sharpening focus and more by waking up the brain. Brain scans revealed that these medications activate reward and alertness systems, helping children stay interested in tasks they would normally

Critical minerals are hiding in plain sight in U.S. Mines Researchers found that U.S. metal mines already contain large amounts of critical minerals that are mostly going unused. Recovering even a small fraction of these byproducts could sharply reduce dependence on imports for

Most distant supernova: James Webb sees a star explode at cosmic dawn Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed using the

In the 1500s, rich Europeans ate oranges not for taste — but to show off they weren’t scurvy peasants.
