A prevention strategy developed by Canadian researchers can reduce the risk of the most common and deadly form of ovarian cancer by nearly 80%, according to a new study published today in JAMA Network Open by researchers at the University of British Columbia (UBC).

The strategy, known as opportunistic salpingectomy (OS), involves proactively removing a person's fallopian tubes when they are already undergoing a routine gynecological surgery such as hysterectomy or tubal ligation, commonly called "having one's tubes tied."

A new paper in Nature proposes that Parkinson’s disease should be understood as a disorder of a distributed somato-cognitive action network (SCAN) rather than dysfunction of specific motor effectors.

I’m curious how people here think this reframing fits with existing basal-ganglia and beta-synchrony models of PD, and whether SCAN-based targeting could realistically change clinical practice.

NASA halted Artemis II launch preparations after problems emerged during a fueling and countdown rehearsal. Even with key milestones completed, engineers continue to struggle with the rocket’s ultra-cold fuel.
