This AI spots dangerous blood cells doctors often miss

15:19
A generative AI system can now analyze blood cells with greater accuracy and confidence than human experts, detecting subtle signs of diseases like leukemia. It not only spots rare abnormalities but also recognizes its own uncertainty, making it a powerful support tool for clinicians.

Scientists discover how the uterus knows when to push during childbirth

15:19
Childbirth depends not just on hormones, but on the uterus’s ability to sense physical force. Scientists found that pressure and stretch sensors in uterine muscles and surrounding nerves work together to trigger coordinated contractions. When these sensors are disrupted, contractions weaken and delivery slows. The discovery helps explain stalled labor—and could one day lead to better ways to mana…

Spacecraft capture the Sun building a massive superstorm

15:19
Scientists have pulled back the curtain on one of the most extreme solar regions seen in decades, tracking it almost nonstop for three months as it unleashed powerful space weather. By combining views from two spacecraft—one near Earth and one orbiting the Sun—researchers followed a massive active region as it grew, twisted, and ultimately triggered the strongest geomagnetic storms since 2003.

This strange form of water may power giant planets’ magnetic fields

15:19
At extreme pressures and temperatures, water becomes superionic — a solid that behaves partly like a liquid and conducts electricity. This unusual form is believed to shape the magnetic fields of Uranus and Neptune and may be the most common type of water in the solar system. New high-precision experiments show its atomic structure is far messier than expected, combining multiple crystal patterns…

Extreme heat is breaking honey bees’ natural cooling system

15:19
Honey bees can normally keep their hives perfectly climate-controlled, but extreme heat can overwhelm their defenses. During a scorching Arizona summer, researchers found that high temperatures caused damaging temperature fluctuations inside hives, leading to population declines. Smaller colonies were hit hardest, experiencing the most severe swings. As global temperatures rise, heat waves could …

Scientists discover what’s linking floods and droughts across the planet

8:59
Scientists tracking Earth’s water from space discovered that El Niño and La Niña are synchronizing floods and droughts across continents. When these climate cycles intensify, far-apart regions can become unusually wet or dangerously dry at the same time. The study also found a global shift about a decade ago, with dry extremes becoming more common than wet ones. Together, the results show that wa…

This new sugar tastes like the real thing without the usual downsides

7:53
Scientists at Tufts have found a way to turn common glucose into a rare sugar that tastes almost exactly like table sugar—but with far fewer downsides. Using engineered bacteria as microscopic factories, the team can now produce tagatose efficiently and cheaply, achieving yields far higher than current methods. Tagatose delivers nearly the same sweetness as sugar with significantly fewer calories…

MIT’s smart pill confirms you took your medicine

7:53
MIT engineers have developed a pill that can wirelessly report when it’s been swallowed. Inside the capsule is a biodegradable antenna that sends a signal within minutes of ingestion, then safely dissolves. The system is designed to work with existing medications and could help doctors track adherence for high-risk patients. Researchers hope it will prevent missed doses that can lead to serious h…

A shocking amount of plastic is floating in city air

7:53
Plastic pollution is not just in oceans and soil. Scientists have now found enormous amounts of microscopic plastic floating through urban air, far exceeding earlier estimates. Road dust and rainfall play a major role in moving these particles through the atmosphere. The findings suggest the air may be one of the most important pathways for plastic pollution.

A new test reveals which antibiotics truly kill bacteria

7:53
Some antibiotics stop bacteria from growing without actually killing them, allowing infections to return later. Scientists at the University of Basel created a new test that tracks individual bacteria to see which drugs truly eliminate them. When tested on tuberculosis and other serious lung infections, the method revealed big differences in how bacteria tolerate treatment. The findings could lea…

This common dinner rule makes meals more awkward

7:53
Waiting to eat when your food arrives first feels polite—but it may be mostly for your own peace of mind. Researchers found people feel far more uncomfortable breaking the “wait until everyone is served” rule than they expect others would feel watching it happen. Even being told to go ahead doesn’t fully ease the discomfort. Serving everyone at once could reduce awkwardness and make meals more en…

A hidden brain signal may reveal Alzheimer’s long before diagnosis

12.ledna
Researchers have discovered a brain activity pattern that can predict which people with mild cognitive impairment are likely to develop Alzheimer’s disease. Using a noninvasive brain scanning technique and a custom analysis tool, they detected subtle changes in electrical signals tied to memory processing years before diagnosis. The findings point to a new way of spotting Alzheimer’s early—by lis…

A new crystal makes magnetism twist in surprising ways

12.ledna
Florida State University scientists have engineered a new crystal that forces atomic magnets to swirl into complex, repeating patterns. The effect comes from mixing two nearly identical compounds whose mismatched structures create magnetic tension at the atomic level. These swirling “skyrmion-like” textures are prized for their low-energy behavior and stability. The discovery could help drive adv…

Astronomers discover stars don’t spread life’s ingredients the way we thought

12.ledna
Scientists observing the red giant star R Doradus have found that starlight isn’t strong enough to drive its stellar winds, overturning a long-standing theory. The dust grains around the star are simply too small to be pushed outward by light alone. This raises new questions about how giant stars spread life-essential elements through space. Researchers now suspect dramatic stellar motions or pul…

Physicists thought this mystery particle could explain everything. See what happened

12.ledna
Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision measurements showed neutrinos behaving exactly as expected—without any sign of a hidden fourth type. While this closes off a popular theory, it marks a turning point for the field, pushing researche…
