A new review by a public health expert from the Hebrew University of Jerusalem reveals that finasteride, a common hair-loss drug, has been linked to depression and suicide for over two decades — yet regulators and manufacturers failed to act. Drawing on data from adverse event reports and healthcare records around the world, the study shows consistent psychiatric harm associated with the drug. Despite mounting evidence, neither Merck nor the FDA initiated critical safety studies. The author calls for urgent reform in how medications are monitored and approved.

Researchers generated the most comprehensive single-nucleus transcriptomic atlas of pig intestines to date, covering wild boars and domestic pigs across four key postnatal developmental stages. The study identified 19 major cell types and 58 cellular subtypes, revealed unique neuronal regulation of intestinal inflammatory response in the ileum, and showed why wild boars exhibit stronger immune responses and nutrient absorption than domestic pigs. These findings provide new insights into improving pig feed efficiency and health, while offering valuable references for human intestinal disease research.
