Light-activated SpyLigation can turn on proteins both inside and outside of living cells

Scientists can now use light to activate protein functions both inside and outside of living cells. The new method, called light-activated SpyLigation, can turn on proteins that are normally off to allow researchers to study and control them in more detail.

New AI-based method for virtual staining of histopathological tissue samples

Researchers from the University of Eastern Finland, the University of Turku, and Tampere University have developed an artificial intelligence-based method for virtual staining of histopathological tissue samples as a part of the Nordic ABCAP consortium. Chemical staining has been the cornerstone of studying histopathology for more than a century and is widely applied in, for example, cancer diagnostics.
