Two new online resources help researchers predict how mutations alter protein structure.

A new analysis of the genomes of more than 11,000 people reveals regions that have few mutations, indicating they have important functions.

Modified versions of molecules found in fireflies make brain cells glow so brightly they are visible from outside the body.

Microscopic silicon wires could enable scientists to excite neurons with light without first inserting genes into them.

A new technology that converts near-infrared light to visible light can manipulate neurons nestled deep in the brain.

Two new techniques could help reveal the molecular basis of conditions such as autism.

A maze comprising 37 hexagonal platforms may offer researchers an accurate measure of rodents’ ability to navigate their surroundings.

A new questionnaire assesses the frequency and severity of various behaviors in children with autism.

A new map of DNA structure highlights sequences that regulate the formation of neurons in the developing brain.

A new map that analyzes gene expression one cell at a time shows how various cell types mature and form the brain’s distinctive structures.
