Mitochondrial rewiring may explain why orthoflaviviruses harm humans but persist in mosquitoes

Orthoflaviviruses reshape mitochondrial structure, metabolism, redox signaling, and quality control differently across human and mosquito models, helping explain their contrasting infection outcomes. The review highlights mitochondrial pathways that may support acute cellular damage in vertebrates but persistent, non-lethal infection in mosquitoes, pointing to potential antiviral targets.

Social media isn’t simply good or bad for young people, and this review shows why

Social media can support connection, self-expression, help-seeking, and community among adolescents and young adults, but problematic use is associated with depression, anxiety, loneliness, poor sleep, and body image concerns.

AI took on doctors in simulated video consultations, and the results were striking

Google researchers developed AMIE, a Gemini-based multi-agent system combining real-time audio-visual perception, clinical reasoning, and low-latency dialogue for simulated video consultations. In a randomized OSCE across 100 clinical scenarios, AMIE Video matched or exceeded primary care physicians across core clinical measures, while patient actors preferred video over text, although real-world clinical validation is still needed.
