he approval of new antibody medications for Alzheimer's disease – lecanemab and donanemab – and diagnostic tests in the blood mark the beginning of a new era in Alzheimer's disease diagnosis and treatment. However, without rapid reform in healthcare systems, public policy, and societal attitudes, their potential will not be fully realised, argue 40 leading Alzheimer's disease experts in The Lancet Series on Alzheimer's disease.

Six out of 10 music fans say they have been sexually harassed or assaulted at a live gig in the US, suggest the results of a survey, published online in the journal Injury Prevention. Women are more than twice as likely as men to have been affected, the responses indicate, but various barriers prevented most respondents from reporting the incident at the time.

Reducing polarization and "partisan animosity"—the distrust and hatred of the other party—is remarkably difficult, according to a new study published in the Proceedings of the National Academy of Sciences evaluating past attempts.

A new study published in the journal Preventive Medicine explores food insufficiency and financial challenges among families after multiple states stopped providing emergency allotments of SNAP benefits provided during the height of the COVID-19 pandemic. SNAP benefit reductions were associated with increased difficulty affording both food and household expenses among SNAP-participant families, particularly among those with children. The risk of food insufficiency—a narrow measure that indicates that a household has not had enough food to eat within the past seven days—increased by five percentage points after several states ended their emergency allotments in 2021, compared to states that ended this assistance later. Similarly, the risk of difficulty affording household expenses increased by eight percentage points after the emergency allotments ended.
