- Older autistic adults are more likely than non-autistic ones to have experienced falls, bodily injuries, poisonings and self-harm, in addition to various health conditions, according to a population-based study in Sweden. The Lancet Healthy Longevity
- An assessment tool that asks children about their participation and engagement in daily activities — a simplified version of “Picture My Participation” — has been validated in a Chinese-speaking population of autistic and non-autistic children. Scandinavian Journal of Occupational Therapy
- Both deletions and duplications of the 22q11.2 chromosomal region can give rise to autism, but they have distinct neurocognitive profiles, according to a preprint. medRxiv
- An organization that runs 130 autism treatment centers in the United States, funded by a private equity firm, has filed for bankruptcy. Spectrum has previously covered the ramifications of private investment in nursing homes and other care facilities. Reuters
- A machine-learning technique called ‘federated learning’ makes it possible to screen datasets for people who may have autism without plugging their information into a centralized server, thereby skirting privacy issues. Scientific Reports
- Naturalistic environments and situations in the laboratory are helping neuroscientists decode animal behavior. Nature
- Biotech companies are tackling chromosomal conditions such as Angelman and Phelan-McDermid syndromes. Earlier this year, Spectrum reported on an RNA therapy for Angelman syndrome as modeled in monkeys. Labiotech
- Two research groups developed synthetic embryos, or embryoids, from human stem cells, prompting ethical concerns. Spectrum reported on embryoids made from mouse stem cells in October. Nature
- The Swiss drug company Roche has discontinued its work on rugonersen, a gene therapy for Angelman syndrome, after disappointing results from a phase 1 clinical trial. Spectrum covered preclinical data on the therapy in August. FAST
