Safety fears as scientists make first viruses designed by AI

Scientists at Stanford University and the Arc Institute created the first functional bacteriophage viruses designed entirely by AI genome language models, marking a milestone in synthetic biology while raising urgent biosecurity and governance concerns.

Stanford and UCSF researchers discover tau protein infiltrates mitochondria, disrupting energy production in Alzheimer's disease

Scientists at Stanford University School of Medicine and University of California, San Francisco have identified a novel toxic mechanism in which hyperphosphorylated tau protein enters nerve cell mitochondria and reverses electron flow, potentially driving Alzheimer's disease and other neurodegenerative tauopathies.

Top claims

▪The newly discovered mitochondrial pathway of tau is entirely independent of both neurofibrillary-tangle formation and microtubule instability.
▪Reverse electron transport is activated under stress and is generally absent or occurring at very low levels in healthy, unstressed cells.
▪An experimental drug called CPT prevents hyperphosphorylated tau from binding to NDUFS3, blocking reverse electron transport without impairing normal electron flow.
