Researchers have used a modified rabies virus and fluorescent proteins to tag individual nerve cells in the mouse visual cortex. 

To tease apart brain regions involved in forming versus remembering memories, scientists engineered mice whose brain cells could be manipulated and tagged.

A device implanted into mice can modulate brain circuit activity over long periods of time.

With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

Ten years ago, scientists put DNA barcodes in AAV vectors, creating an approach that simplified, expedited, and streamlined AAV screening. 

Evolution imbued ants with an agriculture strategy that optimizes food rewards.

Human activities may be affecting both narrow-ranged plants and widespread ones.

Hunter-gatherers cooked and ate carb-rich rhizomes.

When lacking certain enzymes that help plants coordinate cell division, Arabidopsis thaliana cells grow and collect multiple nuclei.
