AI analysis of 400,000 Reddit posts found that users of drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound reported unexpected symptoms including menstrual changes, chills, hot flashes, and fatigue. Researchers cannot say the medications caused these problems, but the patterns may reveal overlooked signals worth studying.

Scientists found that the 3D organization of DNA is disrupted in several types of brain cells affected by Alzheimer’s disease, altering how important genes are switched on and off. The discovery reveals a previously underexplored layer of the disease that could open new paths for understanding and eventually treating Alzheimer’s.

A massive worldwide survey of physicists has revealed surprisingly little agreement about some of the universe’s biggest mysteries. No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum gravity. One area of stronger agreement stood out: 68% said the Big Bang does not necessarily represent the beginning of time. Researchers say the divisions show just how alive and unsettled the frontiers of physics remain.

Scientists are combining an electron microscope with a quantum computer to squeeze far more information from each electron. The approach could reveal faint details with fewer electrons, helping protect fragile samples that conventional microscopy can damage.

Scientists have engineered yeast to turn PET plastic and agricultural waste into ingredients for protein-rich, 3D-printed cookies called µBites. Developed partly for NASA’s Deep Space Food Challenge, the system can produce proteins, fats, vitamins, and even vanilla flavoring from waste materials. Researchers hope the unusual technology could eventually help address both plastic pollution and food insecurity, while also supplying food in extreme environments such as deep-space missions.
