Bespoke photometry system captures variety of dopamine signals in mice

The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

Timothy Ryan on his pivotal switch from studying particle physics to decoding synaptic transmission

Dissuaded from pursuing theoretical physics and deterred by the “long feedback loop” in experimental physics, the National Academy of Sciences member took inspiration from “polymath” Watt Webb and “visionary” Stephen Smith—and learned to work “completely outside his comfort zone.”

Autism and the cell’s antennae

Many autism-linked genes are somehow tied to cilia, the tiny hair-like sensors that stud a cell’s surface. But the question remains whether, and how, cilia differences contribute to the condition.
