Young donor hearts become biologically older in an old recipient, and an old heart gets biologically younger in a young recipient! The big implication: this could increase the number of organs available for transplant. My latest new story for @nature.com 🧪 #health www.nature.com/articles/d41...

Old hearts age backwards: transplanted organs adjust to host's biological age
Tracking the biological age of grafted organs suggests that donor pools could be expanded to boost organ availability.

Tiny hair cells in the inner ear help us hear. On top of each hair cell is a hair bundle, a sensory organelle that senses and amplifies sound. 👂🏽🧪 ✍🏽 For @physicsmagazine.bsky.social, I wrote about a new #thermodynamics model of energy flow within hair bundles. physics.aps.org/articles/v19...

New paper shows social scientists are sidelining null results. Analysing 100,000 articles across 150 political science journals, it finds 2% of abstracts report null-only findings; >90% highlight significant results. Researchers 10–100x less likely to spotlight nulls: driver of publication bias.

Researchers studied recordings of cicadas to discover that the insects’ singing is synchronized with the Sun's position in the sky. The rapid rise in volume suggests that each cicada starts singing in response to both the light level and its neighbors' behavior.
