A medical examiner has confirmed that Shane Tamura, who killed four people in a Manhattan office tower this summer, was suffering from chronic traumatic encephalopathy. Tamura, a Las Vegas casino worker, shot himself in the chest after the July 28 shooting in a building housing NFL headquarters. The victims included a police officer, a security guard and two office workers. He accused the NFL of hiding evidence of brain injuries. A note found in Tamura's wallet revealed his self-diagnosis and urged the study of his brain. Tamura played high school football in California a decade ago but never played in the NFL.

Health Secretary Robert F. Kennedy Jr.'s new vaccine advisers added confusion Friday to this fall's COVID-19 vaccinations. For the first time since the shots were developed, the group has declined to recommend their use — instead leaving the choice up to those who want them. The Food and Drug Administration recently put new restrictions on this year's shots from Pfizer, Moderna, and Novavax, reserving them for people over 65 or younger ones at higher risk. The Centers for Disease Control and Prevention advisers declined to recommend that those people seek a shot but narrowly avoided urging states to require a prescrption for those who want one.

Social media has a huge influence on skincare routines, often promoting complex do-it-yourself regimens aimed at keeping a youthful appearance. But dermatologists say many of these viral products are unnecessary, even if they feel nice, and some can cause more problems than they fix. Real experts recommend a simple routine including a gentle cleanser, moisturizer, and sunscreen with at least SPF 30. Protecting your face from the sun's UV radiation is crucial. Retinol creams and chemical exfoliants can help smooth out wrinkles, but should be used carefully. And those really expensive products? Many share the same ingredients as the much cheaper ones.
