Web app tracks pupil size in people, mice
The app relies on artificial intelligence and could help researchers standardize studies of pupil differences in autistic people and in mouse models of autism.
New library catalogs the human gut microbiome
Researchers put hundreds of gut bacteria strains through their paces to chart the compounds each creates — and to help others explore the flora's potential contribution to autism.
New unified toolbox traces, analyzes neurons
‘SNT’ helps researchers sift through microscope images to reconstruct and analyze neurons and their connections.

Worms help untangle brain structure/function mystery
The synaptic connectome of most animals bears little resemblance to functional brain maps, but it can still predict neuronal activity, according to two preprints that tackle the puzzle in C. elegans.
