Researchers developed a novel protein fiber that tracks transcriptional events over time in living cells. This could shine a light on gene regulation during development or after cellular perturbations.
In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
