Young Boy Never Broke Again.
1. Loneliness presents a profound public health threat akin to smoking and obesity, U.S. Surgeon General Vivek H. Murthy warned in an advisory issued Tuesday that aims to rally Americans to spend more time with each other in an increasingly divided and digital society. Murthy said half of U.S. adults experience loneliness, which has consequences for mental and physical health, including a greater risk of depression, anxiety — and perhaps more surprisingly, heart disease, stroke and dementia. His advisory calls for a collective effort to “mend the social fabric of our nation,” including teaching children how to build healthy relationships; talking more to relatives, friends and co-workers; and spending less time online and on social media if it comes at the expense of in-person interactions.

2. Many people who have come close to death or have been resuscitated report a similar experience: Their lives flash before their eyes, memorable moments replay, and they may undergo an out-of-body experience, sensing they’re looking at themselves from elsewhere in the room. Now, a small study mapping the brain activity of four people while they were dying shows a burst of activity in their brains after their hearts stop. The authors say the finding, published today in the Proceedings of the National Academy of Sciences, may explain how a person’s brain could replay conscious memories even after the heart has stopped. It “suggests we are identifying a marker of lucid consciousness,” says Sam Parnia, a pulmonologist at New York University Langone Medical Center who was not involved in the study. Although death has historically been medically defined as the moment when the heart irreversibly stops beating, recent studies have suggested brain activity in many animals and humans can continue for seconds to hours.
