Workers installing hammock poles on Michigan State University's campus in August 2023 unexpectedly unearthed the buried stone foundation of an old observatory. Built in 1881 and demolished in the 1920s, the small structure had been covered over for decades. Archaeologists and university staff identified the masonry as part of that 19th-century building, making it a notable historical find on a modern college lawn.

Researchers at Speech Graphics, UC San Francisco and UC Berkeley report a brain–computer interface that helped a woman who lost speech after a stroke communicate again. Tiny electrodes were placed on the surface of her brain to record neural activity while she attempted to speak. That recorded activity was decoded into written text, a synthetic voice and real-time facial animation using software originally developed for video-game characters such as those in The Last of Us Part II and Hogwarts Legacy.

Scientists and doctors point out that many health problems run in families, and the diseases now affecting older baby boomers can offer a warning about what people might face later in life. Advances in DNA sequencing make it possible to find gene variants that raise the chances of heart disease, diabetes and some cancers. Identifying those risks early gives doctors and patients options for monitoring, preventive treatment and tailored medical care.
