A new medical large language model (LLM) achieved over 91 percent accuracy in identifying female participants diagnosed with major depressive disorder after analyzing a short WhatsApp audio recording where participants described their week, according to a study published January 21, 2026 in the open-access journal PLOS Mental Health by Victor H. O. Otani, from Santa Casa de São Paulo School of Medical Sciences and Infinity Doctors Inc., Brazil, and colleagues.

The presence of S. jamesii starch on tools, combined with earlier genetic, ecological, and ethnographic research, indicates that Indigenous people intentionally transported, cultivated, and managed the plant across the Four Corners region. These activities define an “anthropogenic range” created through extensive trade networks and long-term use, a key indicator of early domestication.

A new membrane technology stemming from the research led by teams from India could change how industries separate chemicals, reducing energy use and improving water recycling. With a nature-inspired design, the ‘POMbranes’ developed by the scientists are built from molecular units with permanent one-nanometre openings. When assembled into thin films, these openings act as fixed gateways, allowing only smaller molecules to pass, enabling highly selective filtration without the need for traditional heat-driven methods, such as evaporation. The membrane’s flexibility, stability, and lower energy demand make it attractive for use in industries such as textiles and pharmaceuticals.
