This story was published in partnership with The Trace , a nonprofit newsroom covering gun violence in America. Five years ago today, a 22-year-old college dropout fatally stabbed three people at his apartment in Isla Vista, California, then shot 11 people near the campus of University of California, Santa Barbara, killing three of them, before shooting himself to death. Advertisement In an email manifesto he sent out before his rampage, and in YouTube videos discovered afterward, the gunman made his motivation clear: He was angry that he was still a virgin and that women preferred other men over him. “I don’t know why you girls aren’t attracted to me, but I will punish you all for it,” he said in his final video. The targets of his attack, he said, were “the very girls who represent everything I hate in the female gender: The hottest sorority of UCSB.” The Isla Vista killer identified himself as an “incel,” or a member of an … [Read more...] about In the Years Since the Isla Vista Shooting, the Incel Subculture Continues to Inspire Gunmen
Sleepwalking is equal parts fascinating and terrifying. The notion we can be in control of our bodies without having any responsibility for what we do is incredibly unnerving. But what actually happens in your brain (and your body) when you sleepwalk? Here's what science has found out. Top image: Sergey Nivens/Shutterstock.com The Hair-Raising History of Sleepcrime Sleepwalking has been riveting drama, ever since Lady Macbeth wondered if that was a dagger she saw before her, the handle towards her hand. The unquiet mind, forced to wander, acting out unconscious impulses. It's so dramatically satisfying that it's a shame that the providers of this entertainment can't fully enjoy it. History, ancient and recent, provides us with hair-raising tales. Advertisement Some legends about sleepwalking claim that the walkers themselves sometimes brave danger. (And they occasionally do. One 15-year-old girl was found sleeping at the top of a 150 foot crane after … [Read more...] about How Can Dreams Control Your Body? The Science Of Sleepwalking

Hurricane Maria was the deadliest storm in modern U.S. history. And the damage didn’t end when the storm clouds cleared back in September 2017. Especially not for Puerto Rico’s youngest. A new study—the largest post-disaster survey ever conducted in the U.S.—found that students from grades 3 to 12 across the entire island had, to put it bluntly, gone through some serious shit. As a result, more than 7 percent reported symptoms of post-traumatic stress disorder, or PTSD. While this isn’t exactly surprising, it’s still pretty awful. Advertisement Published in the JAMA Network Open journal last week, the study involved distributing individual surveys in Spanish to all the students in the island’s public school system between February and July 2018. It required an effective partnership between the Puerto Rico Department of Education and researchers at the Medical University of South and Carolina, Carlos Albizu University in San Juan, and the … [Read more...] about Hurricane Maria Left Thousands of Puerto Rican Children Experiencing Symptoms of PTSD, Survey Finds
Chronic traumatic encephalopathy, or CTE, is a diagnosis for dead people. Last month, Junior Seau was found in his home in Oceanside, Calif., with a fatal self-inflicted gunshot wound to the chest. A familiar sequence unfolded: His brain was requested by both the Brain Injury Research Institute and Boston University's Center for the Study of Traumatic Encephalopathy—the two main brain banks chasing damage in former football players. If the family consents, the brain will be sliced open and put under a microscope. Given Seau's profession and the nature of his demise, the expectation is that the tissues will show a buildup of a protein called tau, creating tangles like the ones found in victims of Alzheimer's disease. But so what? It's one more brain, to go with the 60-plus brains of former players who have already demonstrated postmortem signs of CTE. Advertisement The question, after a decade of brain-slicing autopsies, is when any of this will help players before they're … [Read more...] about Can Science See Inside An NFL Player’s Skull Before It’s Too Late?
