Dust from asteroid Bennu is revealing a surprising origin story for life's building blocks. New research suggests some amino acids formed in frozen ice exposed to radiation, not warm liquid water as scientists long believed. Isotopic clues show Bennu ...

Scientists have uncovered evidence of a massive underground lava tube hidden beneath the surface of Venus, revealing a new layer of the planet's volcanic history. By reexamining radar data from NASA's Magellan spacecraft, researchers identified what ...

A newly identified protein may hold the key to rejuvenating aging brain cells. Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle ...

Long before agriculture, humans were transforming Europe's wild landscapes. Advanced simulations show that hunting and fire use by Neanderthals and Mesolithic hunter-gatherers reshaped forests and grasslands in measurable ways. By reducing ...

A new scientific review challenges the headline-grabbing claim that Yellowstone's returning wolves triggered one of the strongest trophic cascades on Earth. Researchers found that the reported 1,500% surge in willow growth was based on circular ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit -- but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, this icy world could still surprise us.

Scientists studying a rock sample collected by NASA's Curiosity rover have uncovered something tantalizing: the largest organic molecules ever detected on Mars. The compounds -- decane, undecane, and dodecane -- may be fragments of fatty acids, which ...

Coral reefs, worth an estimated $9.8 trillion a year to humanity, are in far worse shape than previously realized. A massive international study found that during the 2014-2017 global marine heatwave, more than half of the world's reefs suffered ...

Even when Earth was locked in its most extreme deep freeze, the planet's climate may not have been as silent and still as once believed. New research from ancient Scottish rocks reveals that during Snowball Earth -- when ice sheets reached the ...

Swapping just an hour of TV a day for something more active could significantly lower the risk of developing major depression--especially in middle age. A large Dutch study tracking more than 65,000 adults over four years found that replacing 60 ...
