NASA’s Psyche spacecraft uses Mars as a giant slingshot toward a mysterious metal world

8:26
NASA’s Psyche spacecraft just used Mars as a giant gravitational slingshot to continue its journey toward a strange metal rich asteroid. The close flyby boosted the spacecraft’s speed by about 1,000 mph while also producing rare crescent images of Mars glowing through its dusty atmosphere.

Massive supercomputer simulations unlock cosmic magnetic mystery

8:26
Scientists used some of the most advanced plasma simulations ever created to uncover how the universe builds enormous magnetic fields out of turbulence. The discovery could reshape our understanding of stars, black holes, neutron star collisions, and dangerous solar eruptions.

Scientists discover a giant “planet factory” beyond Jupiter

8:26
Scientists believe a dust-filled ring just outside Jupiter acted like a cosmic “planetesimal factory,” producing multiple generations of early space rocks with very different compositions. The discovery may finally explain the origins of several mysterious meteorite types that have survived since the birth of the Solar System.

USC scientists discover a hidden Alzheimer’s trigger and a possible way to shut it down

7:21
USC researchers have identified potential new drug compounds that may reduce the brain inflammation linked to Alzheimer’s disease, especially in people with the high-risk APOE4 gene. The compounds target cPLA2, an enzyme that seems to fuel harmful inflammation while also being important for normal brain activity.

Eating more beans and soy could slash high blood pressure risk by nearly 30%

6:48
Eating more beans, lentils, chickpeas, tofu, and other soy foods could be a surprisingly powerful way to fight high blood pressure. A major analysis of studies from around the world found that people with the highest intake of legumes were 16% less likely to develop hypertension, while those eating the most soy foods had a 19% lower risk.

This prehistoric fish may explain how animals first walked on Earth

16:00
Scientists have peered inside the skull of a 380-million-year-old Antarctic fish that was closely related to the first animals to walk on land, revealing surprising clues about how life began its move out of the water. Using advanced neutron imaging, researchers discovered that Koharalepis jarviki had features suited for living near the water’s surface, including openings in its skull that may ha…

100-million-year-old bug had crab-like claws unlike any known insect

16:00
Deep inside 100-million-year-old amber from Myanmar, scientists uncovered a bizarre ancient bug with clawed front legs that look more like a crab’s pincers than anything seen in modern insects. The discovery is so unusual that researchers say these crab-like “chelae” evolved independently in this lineage, making it only the fourth known example of such structures appearing in insects at all.

Scientists discover why Ozempic and Wegovy weight loss eventually plateaus

16:00
New NIH research reveals that semaglutide sparks different responses inside appetite-controlling brain cells, offering fresh insight into why GLP-1 weight-loss drugs don’t work the same for everyone. Scientists also found a possible way to extend the drugs’ effects, potentially helping patients push past weight-loss plateaus.

AI won’t replace you but someone using AI might

16:00
Generative AI is transforming the workplace faster than ever, but new research from the University of Vaasa suggests the biggest threat may not be AI itself — it’s falling behind in learning how to use it. Researcher Zhe Zhu found that employees who see tools like ChatGPT and Gemini as helpful collaborators rather than job-stealing rivals tend to be more engaged, adaptable, and optimistic about t…

Common heart drug taken by millions found useless — and possibly dangerous

16:00
A massive international study could upend 40 years of heart attack treatment. Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite being given to millions worldwide. Even more surprising, women taking the drugs faced a higher risk of death, repeat heart attack, or hospitalizat…

Scientists discover why some DNA-doubled cells refuse to die

16:00
Scientists have uncovered a surprising twist in how cells behave when division goes wrong. Sometimes a cell successfully copies its DNA but fails to split into two, leaving it with double the genetic material — a mistake linked to aging, cancer, and other major diseases. Researchers discovered that not all of these failures are equal.

Adorable tiny blue octopus found nearly 6,000 feet beneath the Galápagos

25.května
A mysterious little blue octopus discovered nearly 6,000 feet beneath the waters of the Galápagos Islands has officially been identified as a brand-new species. About the size of a golf ball, the tiny creature stunned researchers during a deep-sea expedition when it suddenly appeared on camera, crawling across the ocean floor near an underwater mountain.

Beet juice lowers blood pressure in older adults in just 2 weeks

25.května
Drinking nitrate-rich beetroot juice may do more than support heart health — it could actually reshape the bacteria living in the mouth in ways that help lower blood pressure in older adults. In the largest study of its kind, researchers found that older people who drank concentrated beetroot juice twice daily for two weeks experienced noticeable blood pressure reductions, while younger adults di…

Scientists discover hidden liver switch that cuts harmful cholesterol

25.května
Scientists at UT Southwestern have uncovered a surprising new “master switch” that helps control how much cholesterol the liver sends into the bloodstream. The newly identified protein, HELZ2, works by shutting down the genetic instructions needed to produce apoB — a key building block of the cholesterol-carrying particles linked to clogged arteries and heart disease.

Scientists supercharge natural killer cells to fight aggressive cancers

25.května
Scientists at McGill University have found a way to supercharge the immune system’s natural killer (NK) cells, helping them break through the defenses tumors use to stay alive. By temporarily blocking two proteins, researchers turned these cells into far more effective cancer fighters against difficult cancers like leukemia, glioblastoma, kidney cancer, and triple-negative breast cancer.
