Your social life may leave a mark on how fast you age

Rss Feed - Wed, 08/12/2026 - 23:56
Positive social experiences were associated with longer survival, while childhood adversity predicted shorter survival in a 1,309-person longitudinal cohort followed for nearly 15 years. Epigenetic aging, particularly GrimAge2, emerged as the strongest potential pathway linking social experiences with mortality risk.

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

Rss Feed - Wed, 08/12/2026 - 22:34
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

Rss Feed - Wed, 08/12/2026 - 21:46
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. The review finds that mental health effects depend less on screen time alone than on how social media is used, what content people encounter, and their individual, developmental, and cultural context.

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

Rss Feed - Wed, 08/12/2026 - 21:02
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.

Scientists have combined Artificial Intelligence (AI), genetics and gut microbiome analysis to shed new light on one of the most serious complications of Crohn's disease: intestinal fibrosis, the irreversible scarring of the bowel that often leads to surgery.

Mitochondrial gene RTN4IP1 drives triple-negative breast cancer metastasis

Rss Feed - Wed, 08/12/2026 - 15:28
Triple-negative breast cancer accounts for approximately 15% of all breast cancer cases. It is characterized by the absence of estrogen receptor, progesterone receptor, and HER2 expression, rendering it insensitive to conventional endocrine and targeted therapies.
