First Brain Cell Atlas: Clues to Neurodevelopmental and Psychiatric Disorders
What is a Brain Cell Atlas? The Brain Cell Atlas is a comprehensive roadmap of the brain’s cellular landscape. By cataloging the diverse types of brain cells, their gene activity, and how they interact across different regions and developmental stages, scientists gain a detailed view of how the brain is built and functions. Recent draft…

Ancient Lead Exposure Shaped the Evolution of the Human Brain and Language
Ancient Lead Exposure: A Hidden Thread in Human Evolution New findings published in Science Advances reveal that our ancestors faced intermittent lead exposure for nearly two million years, long before industrial activity. The study stitches together fossil geochemistry, brain organoid experiments, and evolutionary genetics to propose that the toxic metal may have subtly steered the…

Biological Scars in DNA: How Child Maltreatment Reshapes the Brain
Overview: Childhood trauma leaves more than scars Child maltreatment, encompassing abuse and neglect, is a grievous public health issue worldwide. Beyond immediate emotional distress, adverse experiences in childhood can ripple through biology, influencing how genes are regulated and how the brain develops. A recent study from Japanese researchers provides a clearer picture of the molecular…
