Cell diversity: Researchers described 11 clusters of cortical microglia based on RNA transcripts during mouse embryonic development.
- Facilitated-communication strategies for minimally verbal autistic people are biased in ways that may be harmful, because facilitators often override the voice of the autistic person. Spectrum has previously covered the controversy involving facilitated communication, a technique the research community has largely discredited. Current Developmental Disorders Reports
- Based on a cognitive assessment only, about 63 percent of autistic children are considered to have intellectual disability; adding an adaptive behavior assessment lowers the proportion to about 40 percent, and minimizes racial and ethnic disparities. Autism Research
- Girls with Rett syndrome have hearing deficits — as assessed by electrophysiological responses to sounds — that may contribute to their speech challenges. Rett Syndrome News
- A 2022 paper about pollutants and autism has been retracted because of irregularities in some of the Western blot images. Environmental Science and Pollution Research
- A research program on siblings of autistic children has been expanded from two to four sites in the United States and Canada. Autism Science Foundation
