A platform that keeps human skin discarded after surgery alive outside the body for up to a month and uses it to train AI models has been unveiled. Outer Bioscience has built a closed research system combining living human skin data with AI to identify new cosmetic ingredients. The company sources de-identified tissue through biobank networks, tests AI-predicted chemicals on living skin and feeds results back into its models. It focuses on commercialising cosmetic ingredients through safety testing and licensing.

The World Health Organization issued updated guidance saying up to 45 percent of dementia cases worldwide could be prevented or delayed.
