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.
A bevy of genes known to be active during human fetal and infant development first appeared at the same time that the prefrontal cortex—the area of the brain associated with human intelligence and personality—took shape in primates.
A study that identified genes linked to communication between different areas of the brain has been retracted by its authors because of statistical flaws.
The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.
A new study shows that the brains of Alzheimer’s disease patients have a greater viral load, while another study in mice shows infection leads to amyloid-β build up.
