The tea in your kombucha changes more than just the taste

17:27
Scientists discovered that kombucha’s flavor, chemistry, and antioxidant activity vary dramatically depending on the tea used to make it. Green and oolong tea kombuchas emerged as the most biologically active, while fermentation transformed each tea into a distinctly different beverage.

This four-winged dinosaur may have terrorized Earth's earliest birds

17:27
A newly discovered feathered dinosaur called Jian changmaensis may be the missing predator responsible for mysterious piles of crushed prehistoric bird bones in China. The four-winged glider, a close cousin of Velociraptor, helps reveal how early birds and their dinosaur relatives shared the same ancient landscape.

A rare interstellar visitor triggered a SETI search for alien technology

17:27
SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the rapid-response observations helped confirm the object's natural origin and showcased how future interstellar visitors can be investigated for signs of intelligent life.

A tiny diamond defect could reveal a mysterious new kind of magnetism

17:27
A newly proposed quantum sensing technique could make it much easier to identify one of physics’ newest and most intriguing classes of magnets: altermagnets. These unusual materials, discovered only a few years ago, appear to combine the speed and efficiency of antiferromagnets with some of the useful electronic properties of traditional magnets, making them promising candidates for next-generati…

One of the world’s most popular weedkillers may be fueling deadly superbugs

17:27
Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller. The discovery suggests that agricultural herbicides may be helping antibiotic-resistant microbes survive and spread far beyond healthcare settings.

Hidden bird species discovered in Japan after DNA reveals a stunning secret

17:27
A bird long thought to be a single rare species in Japan has turned out to be two. Scientists discovered that the elusive Ijima’s Leaf Warbler and a newly identified Tokara Leaf Warbler look almost identical, but their DNA and songs reveal they are distinct species. The finding marks Japan’s first new bird species discovery in more than 40 years and highlights how modern genetic tools are uncover…

Scientists finally solved how H5N1 bird flu hid in dairy cows

17:27
Researchers uncovered why H5N1 bird flu attacks cows’ udders instead of their lungs: the virus’s preferred receptors are concentrated in mammary tissue. The breakthrough could help scientists predict future bird flu jumps and spot unusual infections before they spread widely.

New brain study reveals speech learning works differently than we thought

17:27
A new study suggests that learning and remembering speech relies more on how the brain processes sounds and sensations than on the areas that control mouth and face movements. The discovery could reshape speech therapy and help improve future brain-based communication technologies.

Scientists open a million-year-old time capsule hidden beneath New Zealand

10:02
A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō. The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived.

NASA’s Cold Atom Lab is creating one of the weirdest forms of matter in space

10:02
NASA’s upgraded Cold Atom Lab is turning the International Space Station into a frontier for quantum research, creating ultra-cold matter that behaves in astonishing ways. The experiments could unlock new discoveries about the universe while paving the way for powerful future technologies in space and on Earth.

Meteorite reveals a lost moon-sized world from the dawn of the solar system

10:02
A rare meteorite has revealed evidence of a massive lost world that once orbited the young Sun before being destroyed in a catastrophic collision. The discovery suggests some early planets formed from dramatically different materials than Earth and Mars, rewriting part of the solar system’s origin story.

This emerging treatment is helping people avoid knee replacement surgery

5:39
A minimally invasive treatment called GAE is helping people with chronic knee pain get back to gardening, cycling, and other activities without undergoing knee replacement surgery. Early studies suggest the procedure can provide years of relief by reducing inflammation inside the joint.

Scientists say most people need more protein than current guidelines suggest

5:39
A new review suggests that doing more exercise and eating more protein than current minimum recommendations may help people stay stronger, sharper, and more independent as they age. The goal isn't building a beach body—it's extending healthspan and maintaining the ability to fully enjoy life for decades longer.

A common vitamin could help fight one of the deadliest brain cancers

22.června
A clinical trial is exploring whether high doses of vitamin B3 could give patients with glioblastoma a better chance against the aggressive brain cancer. Scientists found that niacin may help revive immune cells that tumors shut down, allowing them to attack cancer more effectively. Early results have been promising, with patients showing significantly better progression-free survival than expect…

Butterfly that barely ages could help unlock longevity secrets

22.června
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species. Even more surprising, some show little sign of physical decline as they age. Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helping them stay healthy for longer.
