New genetic test predicts obesity before you start kindergarten

A groundbreaking study involving genetic data from over five million people has uncovered how our DNA can predict obesity risk as early as childhood. The new polygenic risk score outperforms previous methods, helping to identify high-risk children before weight issues develop paving the way for early lifestyle interventions. ​A groundbreaking study involving genetic data from …

It’s not that you look—it’s when: The hidden power of eye contact

A groundbreaking study from Flinders University reveals that it’s not just making eye contact that matters, but precisely when and how you do it. By studying interactions between humans and virtual partners, researchers discovered a powerful gaze sequence that makes people more likely to interpret a look as a call for help. Even more surprising: …

Princeton study maps 200,000 years of Human–Neanderthal interbreeding

For centuries, we’ve imagined Neanderthals as distant cousins — a separate species that vanished long ago. But thanks to AI-powered genetic research, scientists have revealed a far more entangled history. Modern humans and Neanderthals didn’t just cross paths; they repeatedly interbred, shared genes, and even merged populations over nearly 250,000 years. These revelations suggest that …

Can zebrafish help humans regrow hearing cells?

Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different supporting cells in zebrafish divide and regenerate, offering clues to how mammals might someday tap into similar regenerative powers. ​Zebrafish can regenerate sensory hair …
