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.

South Korea's flag carrier Korean Air will begin weighing passengers and their carry-on luggage at Gimpo and Incheon airports. The Ministry of Land, Infrastructure and Transportation has required the checks to collect actual passenger weights for aircraft weight-and-balance calculations. Airline officials say measuring passengers helps crews calculate load distribution, takeoff performance, and fuel needs more accurately than relying on assumed average weights. Officials emphasize it is about technical calculations, not personal data collection.

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.

Archaeologists in Poland have uncovered the skeleton of a child from the 17th century in a graveyard near Dąbrowa Chełmińska. The body was interred face down, and a small triangular padlock was placed beneath the foot bones. Researchers interpret the unusual position and the lock as deliberate measures connected to local burial customs intended to prevent the deceased from returning to harm the living.
