The Sonoran Desert toad secretes 5-MeO-DMT, a potent psychedelic compound currently being investigated as a potential treatment for depression. However, ongoing clinical trials face significant methodological challenges, including short observation periods and difficulties in maintaining double-blind conditions. Due to the toads' high toxicity to pets and the ethical concerns of harvesting them, experts strongly advocate for synthesizing the compound in a laboratory instead.

Studies suggest that taxi drivers have lower rates of Alzheimer's disease because navigating complex spatial environments may help delay cognitive decline. Although this points to potential neuroprotective benefits from mentally demanding work, researchers caution that more studies are needed to fully confirm these findings.

A New Mexico judge has ordered Meta to pay $942 million after ruling that its social media platforms created a public nuisance that harmed children and burdened public resources. The decision relies on the state's public-nuisance law and requires a significant portion of the funds to be used to abate the resulting damages. However, critics argue the ruling relies on an overly broad legal interpretation and predict the decision will be vacated upon appeal.

A large-scale evaluation of human reviewers approving AI agent commands across 40,000 runs found that humans missed one in three security threats. The study also revealed that reviewers frequently blocked safe commands, demonstrating significant flaws in current human oversight processes.
