A Tiny Universe in a Bottle: Lab-Made Cosmic Dust Reveals Clues to Life’s Origins Some of the most important chemistry in the universe happens in places no human will ever visit: the outer envelopes of dying stars, the shockwaves of supernovae, and the cold, dense clouds of gas and dust where new stars are born. […]

The World’s Most Mysterious Hum May Finally Have an Answer For decades, people around the world have reported hearing a persistent, low-frequency humming or buzzing sound that no one else can hear and no one can explain. Known simply as “The Hum,” the phenomenon first surfaced in Bristol, England, in the mid-1970s, when dozens of […]

Can Ozempic Fight Cancer? The Evidence Is Not There Yet, Expert Warns In the span of just a few years, a class of drugs originally developed for type 2 diabetes has been credited with transforming obesity treatment, reducing heart attack risk, and even curbing addiction. Now, a new wave of headlines is asking whether GLP-1 […]

AI Blood Test Spots Heart Disease Risk 15 Years Before Symptoms Cardiovascular disease remains the leading cause of death worldwide, claiming approximately 19.8 million lives in 2022 alone. Standard risk assessments, age, blood pressure, smoking history, cholesterol, catch many at-risk patients, but they can miss the earliest biological changes that develop years before a heart […]

During pregnancy, cells cross the placenta in both directions. The mother’s immune cells enter the fetus; the fetus’s cells enter the mother. This phenomenon, known as microchimerism, has been studied for years, primarily in blood and peripheral tissues. A new study posted on the preprint server bioRxiv suggests it may go much further. Researchers have […]

The asteroid that ended the age of dinosaurs 66 million years ago was not an ordinary space rock. New research published in Science Advances has identified the Chicxulub impactor as a CO-type carbonaceous chondrite, one of the rarest and most primitive types of meteorite known, and in doing so, has revised the understanding of how […]

Every conventional computer chip fights a constant war against a fundamental nuisance: the random jittering of atoms and electrons caused by thermal energy. This noise limits how small transistors can be scaled and forces chips to consume vast amounts of energy just to maintain reliable operation. A small but growing community of physicists and engineers […]

Delivering gene therapies to the right cells in the right organs remains one of the hardest problems in medicine. Adeno-associated virus vectors, the current workhorses of gene therapy, have limited cargo capacity, roughly 4.7 kilobases of DNA, and can trigger immune responses that prevent redosing. For Duchenne muscular dystrophy, where the missing dystrophin gene is […]

Einstein’s general theory of relativity predicted that mass bends spacetime, and that light traveling through warped space would follow curved paths, an effect that turns massive objects into cosmic magnifying glasses. More than a century later, the James Webb Space Telescope is using that prediction to peer deeper into the universe than any instrument before […]

Britain’s hottest and sunniest spring on record has created ideal conditions for butterflies, and conservationists are hoping the public will help document what could be a banner summer for the country’s most colorful insects. The Big Butterfly Count, an annual citizen science project run by Butterfly Conservation, opened on July 18 and runs through August […]
