Researchers have discovered the tallest known tree in East Asia — an 84-meter Taiwania fir hidden in Taiwan's remote mountains — while also uncovering dense 'temples of giants' that rank among the most carbon-rich forests on Earth. A meteorite that crashed through a New Jersey roof was found to contain ancient salty fluids and organic chemistry, hinting that liquid water once flowed inside early s...

A landmark study across 11 Latin American countries reveals a lifestyle intervention that boosted cognitive performance by 55% in adults at risk of dementia — and that's just the beginning. New research identifies a previously unrecognized biological phase in the human brain between ages 50 and 75 that could be critical to understanding how dementia develops. Scientists also discovered that when g...

New analysis of lunar far side rocks is upending decades of debate about the early Solar System's most catastrophic era — and the implications for Earth's own history are massive. NASA's Curiosity rover has uncovered a jaw-dropping field of geometric patterns across a Martian valley, offering a rare fossilized glimpse into the Red Planet's ancient wet past. Meanwhile, physicists have pulled off tw...

New research reveals how a single faulty gene copy can collapse the 3D structure of DNA inside your heart — with consequences far bigger than scientists expected. Astronomers have confirmed a giant planet that evaded detection in one of the sky's most-watched star systems for over a decade, while a UK-funded mission races to block out starlight bright enough to hide entire worlds. Scientists have...

Harvard researchers have transformed ordinary knitting into programmable technology capable of acting as sensors and electrical switches, opening the door to a new era of smart wearables. A chemistry breakthrough using 'free electrons' has shattered long-standing rules about which molecules can bond, potentially unlocking drugs that were previously impossible to create. In neuroscience, a single d...

New computer simulations suggest Europa's icy shell may act as a sealed frozen wall, making the search for life in its hidden ocean far more difficult than scientists once hoped. Closer to home, Earth may be twice as vulnerable to extreme solar storms as previously believed, with major implications for our satellite and power grid infrastructure.
