Red hair might seem rare, but its genes are actually becoming stronger than ever. A huge study from Harvard looked at DNA from over 16, 000 people who lived across Europe and parts of the Middle East over the last 18, 000 years. The research team spent seven years gathering and comparing this geneti
A rare genetic flaw might be behind sudden neck artery spasms that can trigger strokes in younger people. These spasms, called cervical internal carotid artery vasospasms, cut off blood flow to the brain without warning. Doctors see this mostly in patients under 50, where one moment they’re fine, th
Scientists are pushing the limits of CAR T-cell therapy, a treatment where a patient’s immune cells get rebuilt to hunt down disease. Right now, it works well against certain blood cancers but struggles with solid tumors and autoimmune conditions. Why? The cells often pick the wrong targets, fail to
A Chinese tech boss is skipping traditional succession planning entirely. Instead of trusting boards or mentoring employees, he’s betting on biology. By paying American women to carry designer babies, he aims to produce an heir with pre-selected traits—like ordering custom products from a menu. This
A study followed people with a specific genetic hearing loss called OTOF‑related deafness for two and a half years after they received a gene therapy. The treatment used a harmless virus to deliver a healthy copy of the missing gene into inner‑ear cells. Researchers checked many things over time, su
Alzheimer’s isn’t just about memory loss—it’s a slow shutdown of the brain’s wiring. For years, scientists have tried to fix this by sending treatments directly to the brain, but the organ’s defenses make it nearly impossible. The tricky part? Most drugs can’t cross the brain’s protective barrier, w
Guatemala’s next attorney general won’t be the same person trying to hold onto power now. Consuelo Porras, who has faced global criticism for years, just lost her chance to serve another term. A group of legal experts quietly decided she didn’t make the final cut after weeks of behind-the-scenes vot
The United Nations will pick its next chief in 2026, with the new secretary‑general starting a five‑year term on January 1, 2027. Several prominent figures have stepped forward to run for the role. One candidate is Rafael Grossi, an Argentine diplomat who has spent the last six years running the In
AMD is finally joining NVIDIA and Intel in the frame generation game, and it’s doing it the open-source way. The company quietly added a new option to its FidelityFX SDK, letting developers tweak how much extra frames get generated. This isn’t just another patch—it’s AMD’s first real step into multi
Gene editing tools like CRISPR let us change DNA, which raises big questions about human nature. It’s no longer just about fixing diseases early—some see this as a chance to solve rare conditions before birth. But others worry we might end up picking traits for our kids, like choosing eye color or h
