A study of 8,300 older adults revealed a surprising salt habit

17:32
A large study of older adults in Brazil found that adding extra salt at the table is still a common habit, especially among men. While too much salt is linked to serious health problems and faster cognitive decline, researchers discovered that women’s salt-shaking habits were tied more closely to lifestyle and diet.

Goethe never knew this 40-million-year-old ant was hidden in his collection

17:32
Scientists examining amber from Goethe’s personal collection discovered three hidden fossil insects, including an extinct ant preserved in extraordinary detail. Advanced 3D imaging allowed researchers to see not only the ant’s outer features but also structures inside its body. The findings offer new clues about the species’ biology and suggest it likely built large nests in trees.

Scientists finally crack an “undruggable” pancreatic cancer target and nearly double survival

17:32
For decades, pancreatic cancer has been one of the most lethal cancers, with few effective treatment options. A new drug, daraxonrasib, targets the KRAS mutation that fuels most pancreatic tumors—something many scientists once thought couldn't be done. In a major clinical trial, the treatment nearly doubled survival for patients with advanced disease and reduced the risk of death by 60%.

Scientists discover vast hidden structure beneath Antarctica’s ice

17:32
A giant fan-shaped network of hidden basins has been discovered beneath East Antarctica, revealing that several well-known subglacial features are actually part of one massive geological structure. The finding sheds new light on Antarctica’s ancient tectonic history and could help scientists better understand how the ice sheet behaves today.

After 20 years, scientists finally shrink a powerful laser onto a chip

17:32
Researchers at EPFL have developed a chip-scale ultrafast laser that performs on par with traditional tabletop femtosecond lasers. The innovation could make advanced laser technologies far smaller, cheaper, and more accessible for applications ranging from medical diagnostics to atomic clocks.

Scientists discover the master clock that controls biological growth and development

17:32
A newly discovered genetic clock acts as the master timekeeper for development, orchestrating crucial bursts of gene activity throughout a worm’s growth. When the clock is disrupted, development stops, offering fresh clues about how growth-related disorders may arise.

Beluga whales keep switching mates and it may be saving their species

10:08
Hidden beneath Arctic waters, beluga whales have long kept their family lives a mystery. By analyzing DNA from more than 600 belugas in Alaska’s Bristol Bay over 13 years, researchers uncovered a surprisingly flexible mating system: both males and females regularly have offspring with different partners over their lifetimes.

Scientists discover a quantum effect that could eliminate batteries

10:08
Researchers have discovered how microscopic imperfections and atomic vibrations can be used to control a powerful quantum effect in an advanced material. The effect can turn alternating electrical signals from the environment directly into the kind of current electronic devices need, without traditional components. As temperature changes, the signal can even flip direction, giving scientists a ne…

Cancer’s favorite escape trick may actually make it easier to kill

10:08
Scientists have uncovered a surprising new way the immune system fights cancer, overturning a core belief that has guided immunology for decades. The research found that when cancer cells shut down a key immune-recognition molecule called MHC I—a common trick used to hide from “killer” T cells—they can actually become more vulnerable to attack by a different group of immune cells known as CD4+ “h…

NASA's Webb detects methane and strange chemistry on interstellar comet 3I/ATLAS

10:08
NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system. The comet also contains exceptionally high levels of carbon dioxide, making it unlike most comets born in our solar system. Scientists believe the methane was hidden beneath the surface and only emerged after solar…

Venus will disappear behind the Moon in a rare June sky event

3.června
June's night sky delivers several must-see events, starting with a close encounter between Venus and Jupiter after sunset. Mercury joins the pair to form a rare three-planet lineup, while the Moon puts on a special show by passing in front of Venus for viewers in parts of the Americas. The month also marks the start of astronomical summer and the return of spectacular deep-sky targets like the Ri…

Scientists simulated a nuclear fireball and found a surprise in the fallout

3.června
Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better understand how radioactive fallout forms. Their experiments revealed that the way vaporized materials cool can dramatically change the particles that eventually form, especially for volatile elements like cesium.

Popular GLP-1 weight-loss drugs linked to lower risks of addiction and overdose

3.června
A massive study of more than 600,000 U.S. veterans suggests that popular GLP-1 drugs such as semaglutide may do far more than help with diabetes and weight loss—they could also fight addiction itself. Researchers found that people taking these medications were less likely to develop substance use disorders involving alcohol, nicotine, cannabis, cocaine, opioids, and other drugs, while those alrea…

A child's tooth and strange green stones uncover a 5,500-year-old mystery

3.června
An ancient mountain cave in the Pyrenees may have served as one of the earliest high-altitude mining camps ever discovered, with evidence of repeated visits spanning thousands of years. The find becomes even more intriguing with the discovery of a child’s remains and clues that deeper excavations could uncover prehistoric burials.

Super Typhoon Sinlaku triggered atmospheric gravity waves visible from space

3.června
One of the most powerful typhoons ever recorded this early in the Pacific season did more than unleash flooding and extreme winds—it sent enormous ripples all the way into the upper atmosphere. As Super Typhoon Sinlaku rapidly exploded into a category 5-equivalent storm, satellites captured rare gravity waves spreading outward like rings on a pond, visible high above Earth through a faint glow in…
