Mayo Clinic discovers rare gene mutation that causes fatty liver disease

12:24
Mayo Clinic researchers have identified a rare mutation in the MET gene that can directly cause metabolic dysfunction-associated steatotic liver disease. The mutation disrupts the liver’s ability to process fat, leading to inflammation, scarring, and potentially cirrhosis. The discovery began with a father and daughter who had the disease without typical risk factors. Large-scale genomic data sug…

A 4,000-year-old sheep reveals the secret of an ancient plague

12:24
A mysterious form of plague that spread across Eurasia thousands of years before the Black Death has finally revealed a crucial clue. Scientists analyzing ancient DNA discovered the bacterium Yersinia pestis in a 4,000-year-old domesticated sheep from a Bronze Age settlement in the Ural Mountains—the first time the pathogen has ever been found in a non-human host from that era. Because this early…

Scientists discover protein that triggers diabetic blindness

12:24
A newly identified protein may hold the key to preventing diabetic blindness. Researchers discovered that LRG1 triggers the earliest damage in diabetic retinopathy by constricting tiny retinal blood vessels and reducing oxygen supply. In mice, shutting down this protein stopped the damage before it could take hold. The finding could pave the way for treatments that protect vision before symptoms …

Physicists finally see strange magnetic vortices predicted 50 years ago

12:24
A team of physicists has experimentally confirmed a long-predicted sequence of exotic magnetic phases in an atomically thin material. When cooled, the material forms tiny magnetic vortices before transitioning into a second ordered magnetic state—exactly as predicted by a famous theoretical model from the 1970s. Observing both phases together for the first time validates key ideas about how magne…

Antarctica has a strange gravity hole and scientists finally know why

12:24
Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity hole” to slow, deep movements of rock inside Earth that unfolded over tens of millions of years. Using earthquake data to essentially create a CT scan of the planet’s interior, researchers reconstruc…

Boosting a key brain protein could help treat Rett syndrome

12:24
Researchers have discovered a new way to increase a key brain protein damaged in Rett syndrome, a rare genetic disorder that affects thousands of children worldwide. Early studies in mice and patient-derived cells show the approach can restore normal brain cell function, raising hopes for future therapies.

Cannabis compounds CBD and CBG may help reverse fatty liver disease, study finds

12:24
CBD and CBG, two non-intoxicating cannabis compounds, may help combat fatty liver disease by boosting liver energy reserves and restoring cellular cleanup systems. In the study, both compounds improved blood sugar control and reduced harmful lipids linked to fatty liver disease. Researchers say the findings point to a promising new plant-based approach to treating metabolic liver disorders.

Koalas survived a devastating population crash and their DNA is bouncing back

12:24
Koalas suffered a massive population decline that left them with dangerously low genetic diversity. However, new genomic research suggests their rapid rebound may be helping reverse some of that genetic damage. As koala numbers rise, recombination is mixing their remaining DNA into new combinations, which can rebuild functional diversity. The findings suggest that fast population recovery can som…

Eating less protein may slow liver cancer growth, study finds

12:24
A Rutgers-led study found that eating less protein may help slow liver cancer in people with impaired liver function. When damaged livers can’t properly clear toxic ammonia from protein metabolism, the excess ammonia can feed tumor growth. In mice, reducing dietary protein lowered ammonia levels, slowed tumor growth, and significantly improved survival.

Scientists create cartilage scaffold that helps the body regrow bone

12:23
Researchers in Sweden have engineered a cell-free cartilage scaffold that can guide the body to rebuild damaged bone. By removing the cells but preserving the structure and natural growth signals, the material acts as a blueprint for the body’s own repair process. In animal studies, it helped regenerate bone without triggering strong immune reactions. The team now plans to scale up production and…

Scientists say most of what you do each day happens on autopilot

12:23
Most of our daily actions may happen without much thought. Researchers found that around 65% of everyday behaviors are triggered automatically by habit rather than conscious decisions. Many of these habits actually support our personal goals, helping us follow through on things like healthy routines. The key to lasting change, scientists say, is building new positive habits while disrupting the c…

Scientists discover tiny ocean fungus that kills toxic algae

12:23
Scientists have discovered a newly identified marine fungus that can infect and kill toxic algae responsible for harmful blooms. The microscopic parasite, named Algophthora mediterranea, attacks algae such as Ostreopsis cf. ovata, which produces toxins that can irritate the lungs, skin, and eyes of people exposed during coastal blooms. Remarkably, the fungus can infect several different algae spe…

Tiny clump of moss helped solve a shocking cemetery crime

12:23
A tiny piece of moss helped expose a cemetery scandal in Illinois, where workers allegedly dug up graves and resold burial plots. By identifying the moss and analyzing its chlorophyll to estimate its age, scientists proved the remains had been moved recently—evidence that helped secure convictions.

Scientists discover the brain protein that drives cocaine relapse

12:23
Cocaine addiction isn’t simply a failure of willpower — it’s the result of lasting biological changes in the brain. Researchers at Michigan State University discovered that repeated cocaine use rewires communication between the brain’s reward system and the hippocampus, the region responsible for memory. A protein called DeltaFosB builds up with continued drug use and acts like a genetic switch, …

This ancient sea creature may already have had a brain

12:23
Advanced 3D reconstructions of the comb jelly’s aboral organ reveal a sensory system far more complex than scientists expected. The organ contains a wide variety of specialized cells and is closely linked to the animal’s nerve network, allowing it to coordinate behavior and orientation in the water. Researchers say it may function as a primitive brain-like center. The discovery suggests that cent…
