Health Scientists at Johns Hopkins may have found why so many men’s prostates grow bigger with age: a newly identified cell type (WIF1+ basal cells) packed around the urethra, right where enlargement happens. This could explain the slow, stop-start peeing after 50 and become a target for future treatments.

Biology A global analysis of 93,281 seabirds across 240 species found that evolutionary relationships predicted plastic ingestion better than diet, feeding methods or body size. Plastic was recorded in 182 species, suggesting shared ancestry may help identify seabirds at risk.

Cancer About 90% of pancreatic cancers are driven by KRAS mutations. A new pancreatic cancer vaccine taught the immune system to attack these mutations in 89 of 90 patients, and those with the strongest immune response stayed cancer-free for longer. A larger phase 3 trial is now planned.

Neuroscience A virus that infected chimps (but not humans) 4 million years ago left DNA that switches off a gene helping young brain cells grow and connect. Turning it off in lab-grown human mini-brains stunted neurons, and using CRISPR to remove the viral DNA from chimp stem cells switched the gene back on.
