Scientists discover a strange property in rice and turn it into a smart material

15:59
Scientists discovered that rice behaves in a highly unusual way: it weakens under rapid compression but stays stronger when pressure is applied slowly. Using this effect, they engineered a new material that reacts differently to gentle movements and sudden impacts. The material can adapt its stiffness automatically, opening the door to safer soft robots and protective equipment that responds inst…

The deadly tapeworm spreading across America has reached the Pacific Northwest

15:59
A potentially dangerous tapeworm linked to severe, cancer-like disease has now been found in the Pacific Northwest, marking its first detection in wild animals along the U.S. West Coast. Researchers discovered the parasite, Echinococcus multilocularis, in 37% of coyotes tested around Puget Sound—a surprisingly high rate for a region where it had never been reported until recently.

NASA reveals Artemis III crew for one of the most complex space missions ever

15:59
NASA has selected the Artemis III crew for a high-stakes 2027 mission designed to test the future of lunar exploration. Astronauts will launch aboard Orion and perform unprecedented docking operations with lunar landers being developed by both Blue Origin and SpaceX. The mission will require a remarkable sequence of heavy-lift rocket launches and complex in-space maneuvers, helping pave the way f…

Scientists built a battery-free device that turns sunlight into fuel

15:59
Scientists have developed an artificial photosynthesis system that essentially regulates itself, eliminating the need for batteries used in many current designs. The key innovation is an electrolyzer that automatically adapts to changing sunlight by altering its electrical properties as it heats up. This keeps solar fuel production more stable while reducing cost and complexity.

James Webb reveals two completely different twilights on an alien world

15:59
JWST has revealed dramatic differences between the dawn and dusk regions of the scorching exoplanet WASP-121 b. Fierce winds appear to carry heat from the planet’s permanent dayside, making the evening side hotter and more expanded. Scientists also found signs that water is being broken apart by extreme temperatures and that mysterious mineral clouds may be shaping the cooler side’s atmosphere.

AI could uncover new physics faster but there’s a surprising catch

15:59
Scientists found that transfer learning can make the search for new physics in the universe much faster, slashing the need for expensive simulations. Yet the approach can backfire when AI relies too heavily on familiar patterns, potentially missing evidence of something truly new.

Scientists turn tofu and cheese waste into tiny CO2-catching beads

15:59
Scientists have developed biodegradable protein beads made from dairy and tofu waste that can capture carbon dioxide from the atmosphere more efficiently than many current technologies. Unlike conventional systems that require large amounts of energy, the new method releases captured CO2 using a simple room-temperature process.

The 1,100-year-old mystery of Montana’s lost bison hunting site finally solved

15:59
For nearly 700 years, Indigenous hunters repeatedly used a bison kill site in central Montana—then suddenly stopped, even though bison were still abundant. Researchers uncovered evidence that recurring, decades-long droughts likely made the site less practical by reducing access to the water needed to process large numbers of animals. At the same time, hunting groups were shifting toward larger, …

Scientists discover a hidden cause of aging cells that can be reversed

8:58
Researchers discovered that declining levels of phosphatidylcholine may be a major cause of age-related mitochondrial dysfunction and loss of cellular energy. Remarkably, boosting this nutrient restored more youthful mitochondrial performance in aging organisms, suggesting some aspects of aging can be slowed or reversed.

That ringing in your ears could be an early warning sign of hearing loss

8:58
A common sign of hearing loss isn’t complete silence — it’s struggling to follow conversations, especially in noisy places. Experts say hearing loss and tinnitus, the ringing or buzzing many people experience, often start when delicate cells inside the ear become damaged from aging or long-term noise exposure. Beyond making it harder to hear, these conditions can affect sleep, concentration, mood…

Scientists propose a radical new theory for how life began on Earth

8:58
Researchers propose that tiny mineral nanoparticles may have been the hidden engines that transformed Earth’s early chemistry into the first building blocks of life. By acting as natural catalysts and energy processors, these “nanozymes” could help explain how lifeless matter gradually became living systems.

Scientists shut down cancer DNA repair to overcome drug resistance

8:57
Cancer cells often survive treatment by fixing the DNA damage that therapy is meant to cause. Researchers found that UNI418 can disrupt this repair ability, leaving cancer cells more exposed. When combined with a PARP inhibitor, it helped resistant cancer cells respond to treatment again. The findings point to a new strategy for overcoming cancer drug resistance.

MIT’s new spacecraft engine could send tiny satellites to Mars

10.června
MIT researchers have shown that one fuel can power both chemical and electric spacecraft thrusters, potentially transforming what small satellites can do. The approach combines quick bursts of speed with highly efficient long-range propulsion in a single compact system. A NASA-supported CubeSat mission will soon test the technology in orbit.

A classic brain test exposed AI's biggest weakness

10.června
Researchers gave top AI models a classic attention test used in psychology and found a major flaw. While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex. Some leading systems fell from over 90% accuracy to nearly complete failure.

Scientists mapped every neural connection in a fruit fly and found a surprise

10.června
A groundbreaking new connectome maps every neural connection in an adult fruit fly’s central nervous system, creating an unprecedented view of how the brain and body work together. The findings suggest that complex behaviors emerge from distributed local circuits rather than a single central controller, offering new clues about intelligence, movement, and brain function.
