Researchers identified a pathway in the male rat brain that psychedelics target. This pathway may explain how these drugs strengthen memories and alleviate psychiatric disease symptoms.

Researchers from Johns Hopkins Medicine and the Johns Hopkins Bloomberg School of Public Health report that an AI-powered lifestyle intervention app for prediabetes reduced the risk of diabetes similarly to traditional, human-led programs in adults. 

In a new study, researchers found high levels of ultrashort-chain per- and polyfluoroalkyl substances (PFAS) in blood samples taken from Wilmington, N.C. residents between 2010-2016. Two ultrashort-chain PFAS – perfluoromethoxyacetic acid (PFMOAA) and trifluoracetic acid (TFA) – were detected at high levels in almost every sample. In contrast, GenX – the chemical that jumpstarted public concern about PFAS in the Cape Fear River Basin – was detected in 20% of the samples. The work adds to the body of evidence that short-chain PFAS can accumulate in the human body.
