Unconventional optogenetics technique spurs long-lasting changes in neuronal activity
Conventional optogenetic manipulations to excite or inhibit neurons stop when the light switches off. A new approach makes the changes last.

Of mice and human interneurons: Q&A with Moritz Helmstaedter
People’s brains have a larger network of inhibitory interneurons than mouse brains do, according to a new study. Changes to that network could contribute to autism or other conditions, says lead investigator Moritz Helmstaedter.

What U.S. science stands to lose without international graduate students and postdoctoral researchers
Neuroscience in other countries will strengthen—at the United States’ expense—as rising visa restrictions and rejections block many international students from enrolling at U.S. institutions and dissuade others from applying.

New dopamine sensor powers three-color imaging in live animals
The tool leverages a previously unused segment of the color spectrum to track the neurotransmitter and can be used with two additional sensors to monitor other neurochemicals at different wavelengths.

Cell ‘antennae’ link autism, congenital heart disease
Variants in genes tied to both conditions derail the formation of cilia, the tiny hair-like structure found on almost every cell in the body, a new study finds.
