New AI blood test predicts heart disease 15 years early
A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems. Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the r…
A tiny universe in a bottle reveals clues to the origins of life
Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found…
The mysterious hum heard around the world may finally have an explanation
The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside th…
Coffee may help the body fight stress and aging through a hidden cellular switch
Scientists may have uncovered one reason coffee is repeatedly associated with healthier aging and lower disease risk. Compounds in coffee appear to activate NR4A1, a receptor that helps protect cells from stress, inflammation, and damage. These protect…
Scientists just discovered a lost branch of Australia’s marsupials
Fossils from Queensland suggest a newly recognized marsupial order may have survived in Australia for around 35 million years, rewriting part of the story of how the continent’s unique mammals evolved. The discovery challenges the idea that Australia’s…
Scientists identify the rare meteorite that killed the dinosaurs 66 million years ago
The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have deli…
Common antidepressant may ease long COVID’s crushing fatigue
A low-cost antidepressant may offer new hope for people struggling with long COVID fatigue. In a randomized clinical trial involving 399 adults, fluvoxamine significantly reduced fatigue and improved quality of life compared with a placebo, making it o…
Popular sugar substitutes linked to faster brain aging
Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake …
A shattered asteroid may have bombarded Earth 800 million years ago
A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Mo…
