Reprogramming ant ‘soldiers’

A Penn study reveals the epigenetic pathway that controls social behavior in carpenter ants, finding that the ants reprogram up to five days after they hatch, while reprogramming was ineffective at the 10-day mark.

Consuming alcohol leads to epigenetic changes in brain memory centers

What drives the biology behind alcohol cravings has remained largely unknown. A new Penn study shows how a byproduct of the alcohol breakdown produced mostly in the liver travels to the brain’s learning system and impacts behavior around environmental cues to drink.

The science of sensations

To confront the ills of the opioid epidemic, scientists must develop a fundamental understanding of the biology of pain. Biologist Ishmail Abdus-Saboor’s work is setting the stage for screening alternative drugs and uncovering new pathways that an opioid-alternative could target.

Engineers solve the paradox of why tissue gets stiffer when compressed

Tissue gets stiffer when it’s compressed. That stiffening response is a long-standing biomedical paradox, as common sense dictates that when you push the ends of a string together, it loosens tension, rather than increasing it. New research explains the mechanical interplay between that fiber network and the cells it contains.
