Three years before the skyscraper-size asteroid Apophis makes its very close (but safe) flyby of Earth, scientists have already begun charting exactly when and where billions of people can watch it sweep across the sky. Speaking at an “Apophis T-3 Years” workshop held earlier this month at the University of Padua in Italy, retired cartographer…

Scientists may have found a way to destroy cancer cells without initially relying on chemotherapy, surgery, or radiation. The approach is called ‘molecular jackhammer’, and it relies on little more than light and a well-established medical molecule. The technique involves using aminocyanine molecules – synthetic dyes already widely used in medical imaging – and stimulating…

There’s no doubt about it: the skies are filling up with satellites that regularly pass overhead, creating light trails that can interfere with stargazing, backyard astronomy, astronomical research, and pose a significant threat to natural ecosystems. The problem stems from the design of the satellites themselves, which include solar arrays that reflect sunlight, creating an…

NASA researchers recently put a new wing design, appearing long and thin with a lightweight structural design, through a series of grueling tests to find its structural limits. What they found left them encouraged about the wing’s potential, even when they pushed it past its intended limits. The 15-foot Structural Wing Experiment Evaluating Truss-bracing (SWEET-15)…

In 2021, Jordan Miller, then an undergraduate student at UT San Antonio, noticed something strange — a sudden and dramatic increase in poison control center calls across the United States seemed to coincide with the FDA approval of semaglutide for weight management. In a study published in the Journal of Medical Toxicology, Miller and her…
