Scientists discovered a small protein region that determines whether plants reject or welcome nitrogen-fixing bacteria. By tweaking only two amino acids, they converted a defensive receptor into one that supports symbiosis. Early success in barley ...
Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, strengthening the mysterious Hubble tension. ...
A sudden X-ray flare from a supermassive black hole in galaxy NGC 3783 triggered ultra-fast winds racing outward at a fifth the speed of light—an event never witnessed before. Using XMM-Newton and XRISM, astronomers caught the blast unfold in real ...
New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star formation, shifts in flowing gas, and even streams of ...
Scientists have confirmed that Nanotyrannus was a mature species, not a young T. rex. A microscopic look at its hyoid bone provided the key evidence, matching growth signals seen in known T. rex specimens. This discovery suggests a richer, more ...
A remarkably clean gravitational-wave detection has confirmed long-standing predictions about black holes, including Hawking’s area theorem and Einstein’s ringdown behavior. The findings also provide the strongest support yet that real black ...
Deep-brain recordings showed that Mounjaro and Zepbound briefly shut down the craving circuits linked to food noise in a patient with severe obesity. Her obsessive thoughts about food disappeared as the medication quieted the nucleus accumbens, the ...
Researchers revealed that the microbial metabolite TMA can directly block the immune protein IRAK4, reducing inflammation and improving insulin sensitivity. The molecule counteracts damage caused by high-fat diets and even protects mice from sepsis. ...
Researchers have built a fully implantable device that sends light-based messages directly to the brain. Mice learned to interpret these artificial patterns as meaningful signals, even without touch, sight, or sound. The system uses up to 64 ...
A large Mayo Clinic study shows that current guidelines fail to detect nearly 90% of people with familial hypercholesterolemia, a common inherited cause of dangerously high cholesterol. Many affected individuals already had early heart disease but ...
XRISM’s high-precision X-ray data revealed unusually strong signatures of chlorine and potassium inside the Cassiopeia A supernova remnant. These levels are far higher than theoretical models predicted, showing that supernovae can be major sources ...
Garlic extract is emerging as a surprisingly powerful contender to chlorhexidine, the long-standing “gold standard” in antimicrobial mouthwashes. A systematic review of clinical studies shows that higher-concentration garlic mouthwash can rival ...

Using less ipilimumab appears to make melanoma immunotherapy both safer and more effective, with dramatically better response and survival outcomes. The findings suggest that reducing side effects ...

Experiments reveal that pond frogs can eat highly venomous hornets without suffering noticeable damage, even after repeated stings. Most frogs successfully consumed hornets, including the notorious ...

Scientists have captured a never-before-seen, high-resolution look at influenza’s stealthy invasion of human cells, revealing that the cells aren’t just helpless victims. Using a groundbreaking ...

Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features ...

Scientists uncovered a surprising four-layer structure hidden inside the hippocampal CA1 region, one of the brain’s major centers for memory, navigation, and emotion. Using advanced RNA imaging ...

SPHERE’s detailed images of dusty rings around young stars offer a rare glimpse into the hidden machinery of planet formation. These bright arcs and faint clouds reveal where tiny planet-building ...

A researcher from the University of Tokyo and a U.S.-based structural engineer developed a new computational form-finding method that could change how architects and engineers design lightweight and ...

Cedars-Sinai scientists have created a new experimental drug called TY1 that helps the body repair damaged DNA and restore injured tissue. The discovery came from studying tiny molecular messages ...

A large study found that people with impaired kidneys tend to have higher Alzheimer’s biomarkers, yet they don’t face a higher overall risk of dementia. For those who already have elevated ...

A low-dose mix of zinc, serine, and branched-chain amino acids boosted neural function and social behavior in autism mouse models. The combination restored more typical synaptic protein patterns and ...

For thirty years, SOHO has watched the Sun from a stable perch in space, revealing the inner workings of our star and surviving crises that nearly ended the mission. Its long-term observations ...

Ant pupae that are fatally sick don’t hide their condition; instead, they release a special scent that warns the rest of the colony. This signal prompts worker ants to open the pupae’s cocoons ...

A surprisingly mature spiral galaxy named Alaknanda has been spotted just 1.5 billion years after the Big Bang—far earlier than astronomers believed such well-structured galaxies could form. With ...

A unique vaccine rollout in Wales gave researchers an accidental natural experiment that revealed a striking reduction in dementia among seniors who received the shingles vaccine. The protective ...

Earth’s orbit is getting crowded with broken satellites and leftover rocket parts. Researchers say the solution is to build spacecraft that can be repaired, reused, or recycled instead of ...

Researchers recreated conditions from billions of years ago and found that Earth’s young atmosphere could make key molecules linked to life. These sulfur-rich compounds, including certain amino ...

Ancient anaconda fossils show that the snakes became giants soon after emerging in Miocene South America. Their size has stayed stable for over 12 million years, even though other huge reptiles went ...

Stanford researchers found that gas stoves expose Americans to surprisingly high levels of nitrogen dioxide—often matching or exceeding outdoor pollution. For millions, cooking alone pushes NO2 ...

Sweat carries a rich mix of biomarkers that advanced wearables can now track in real time. New AI-powered patches analyze biochemical patterns to detect disease risks, medication levels, or stress ...

Scientists found that adult bristleworm eyes grow continuously thanks to a rim of neural stem cells similar to those in vertebrate eyes. This growth is surprisingly regulated by environmental light ...
