CogLinks model reveals how the brain adapts to changing rules
Every day, your brain makes thousands of decisions under uncertainty. Most of the time, you guess right. When you don't, you learn. But when the brain's ability to judge context or assign meaning falters, thoughts and behavior can go astray.

Blocking a key protein halts lung scarring in mouse model of fibrosis
Pulmonary fibrosis is a deadly disease in which the lungs become thickened and scarred, gradually losing their ability to deliver oxygen to the body. Now, scientists at UC San Francisco have identified a key cellular switch that drives this process—and found a way to block it in mice.

How lifestyle and environment reshape the sperm epigenome and why it matters for fertility, embryos and child health
A review in Clinical Epigenetics synthesizes growing evidence that paternal lifestyle and environmental exposures such as diet, obesity, smoking, endocrine-disrupting chemicals, and stress alter sperm epigenetic marks (DNA methylation, histone retention, and small non-coding RNAs). These changes can influence sperm quality and fertilizing ability, early embryo development, assisted reproduction outcomes, and long-term health risks in offspring.

Cancer cells reactivate embryo-like gene editors to fuel growth, research reveals
Cancer cells are known to reawaken embryonic genes to grow. A new study reveals the disease also hijacks the proteins, or "editors," that control how those genes are read.
