Cancer Cells May Fear Rust More Than Apoptosis
A 2025 review places mitochondria at the center of ferroptosis: four firewalls decide whether cancer cells die by lipid peroxidation. This is a mechanism map, not proof of human benefit.

Nine billion DNA letter swaps, pre-drawn as a map: what AlphaGenome Atlas ranks
DeepMind’s AlphaGenome Atlas precomputes molecular effects for about nine billion possible single-letter DNA changes and ranks them with AVI scores. A research traffic map, not a clinical diagnosis.
Why Does an Aging Atrium Become Easier to Disturb? Rapamycin May Press a Metabolic Brake
A mouse and cell study links rapamycin with lower atrial fibrillation susceptibility in an accelerated-aging model, pointing to HIF-1α and mitochondrial metabolism. The findings are mechanistic clues, not proof of human benefit or a reason to self-medicate.
Why force falls faster than muscle size: NMJ NaV1.4 loss and ClC-1 inhibition
Human SFEMG and rodent work in JCI 2026 show sarcopenic weakness can come from postsynaptic NaV1.4 loss at the NMJ, not just wasting. Partial ClC-1 inhibition restored transmission-related force in aged rats; this is not a human drug claim.
Six proteomic clocks in one IPF trial: can a disease drug also move biological age?
Nature Biotechnology embeds six proteomic aging clocks in a phase 2a rentosertib IPF trial. Treated arms show concordant biological-age reductions peaking at week 4, partly dissociated from FVC gains. A dual-purpose design demo, not proof of rejuvenation.
Beyond Weight Loss — How Semaglutide Quiets the Immune Storm in Your Brain
GLP-1 receptor agonist semaglutide reverses high-fat diet-induced hippocampal microglia activation via the IGFBPL-1/PI3K/AKT pathway in mice. This article explores the molecular bridge from gut hormones to brain protection — and the gap between animal data and clinical reality.
When You Need Stem Cells Most, They're As Old As You Are — Can Two Old Drugs Help?
The elderly need autologous stem cell therapy most, yet their stem cells are few and worn out. A 2026 Scientific Reports study briefly treated aged fat-derived stem cells with rapamycin plus nicotinamide, lowering p16, p21 and inflammatory cytokines while restoring differentiation by rebooting the stalled AMPK-mTOR-autophagy loop.
Letting Agents Assign Tasks to Each Other: A Practical Build from tmux to Handoff
How to turn manual copy-pasting across CLI agent terminals into auditable mutual task assignment using dynamic discovery, capacity allocation, and file-first handoffs.
One Month of Local Model Benchmarking: I Overturned My Own Rankings
From acceleration knobs and extreme quantization to a nine-model comparison, a large-sample retest at month's end reshuffled the entire leaderboard. A record of a broken yardstick, small-sample error bars, and the current division of labor between pi and local models.
Cholesterol Is Quietly Aging Your Joints: How a Statin Target Accelerates Osteoarthritis
Osteoarthritis is more than wear and tear. An Advanced Science study in mice and human synovium finds that HMGCR, the statin-targeted enzyme of cholesterol synthesis, runs too hot in synovial fibroblasts, overproduces cholesterol, drives cellular senescence, and fuels synovitis and cartilage breakdown; local joint knockdown of HMGCR in mice reverses senescence and eases pain and cartilage loss.
