Atlas maps how aging reshapes cells

Scientists at Rockefeller University profiled nearly 7 million cells from 21 organs in mice at three ages. The atlas reveals cell-type shifts, coordinated changes across organs, strong sex differences and genomic sites linked to immunity.

Brown study suggests targeting mTORC2 could help fight cancer

Researchers at Brown University report that blocking the mTORC2 protein complex, while leaving mTORC1 active, may stop cancer growth signals without triggering survival pathways. The work offers a new direction for designing cancer drugs.

Mechanical tipping point behind sudden fibrosis

Scientists found a mechanical "tipping point" that makes groups of cells switch quickly from healthy to fibrotic states. Collagen fibers, cell spacing and crosslinking control this abrupt change and affect how far mechanical signals travel.

Oldest RNA found in woolly mammoth from Siberian permafrost

Scientists isolated and sequenced RNA from a woolly mammoth's frozen tissue. The material came from Siberian permafrost and is nearly 40,000 years old; the study shows RNA can survive for very long periods.

Alternative splicing linked to mammal lifespan

A study in Nature Communications compared alternative splicing across 26 mammal species (lifespans 2.2–37 years) and found splicing patterns better predict maximum lifespan than gene activity; the brain shows many lifespan-linked events controlled by RNA-binding proteins.
