HOW MONKEYPOX SPIRALED INTO A CRISISYOUR WEEKLY CHECKUPThis week: The science behind your shower thoughts; how exercise keeps your brain healthy; the CDC’s new relaxed guidelines for COVID-19;why smallpox vaccines fell out of favor; why the monkeypox outbreak keeps getting worse; and the “disease of discovery” that eluded doctors for centuries. PHOTOGRAPH BY ELIZABETH CECIL, THE NEW YORK TIMES VIA REDUX Why do your best ideas come to you in the shower? It’s science. Research from the past 15 years suggests that people may be more likely to have creative breakthroughs or epiphanies when they’re doing a habitual task that doesn’t require much thought—an activity in which you’re basically on autopilot. Now we’re beginning to understand why these clever thoughts occur during more passive activities and what’s happening in the brain.SUBSCRIBER EXCLUSIVEPHOTOGRAPH BY FRITZ HOFFMAN, NAT GEO IMAGE COLLECTION New clues are revealing why exercise can keep the brain healthy SUBSCRIBER EXCLUSIVEPHOTOGRAPH BY NATALIE KEYSSAR, THE NEW YORK TIMES VIA REDUX How your brain perceives time may depend on your income LEARN MOREPHOTOGRAPH COURTESY LAB OF MISFITS The amazing ways your brain determines what you see LEARN MOREPHOTOGRAPH BY ROBERT CLARK How the human brain makes, remembers, and forgets memories LEARN MOREPHOTOGRAPHS BY JAHI CHIKWENDIU, WASHINGTON POST/GETTY IMAGES (LEFT) AND SMITH COLLECTION, GADO/GETTY IMAGES (RIGHT)Why smallpox vaccines fell out of use—and what that means for monkeypox Smallpox was eradicated in 1980, meaning the young adults of today weren’t alive when smallpox vaccines were routine. Although monkeypox is far less dangerous than smallpox, the two viruses are related—and there is some evidence that the smallpox vaccine provides protection from monkeypox. But experts warn that many questions remain about the protection they provide.WHAT YOU NEED TO KNOW HISTORY: How a smallpox epidemic nearly derailed the American Revolution +PHOTOGRAPH BY CDC How did the monkeypox outbreak get so bad, so fast? The U.S. had diagnostic tests available to contain this virus—along with two vaccines.
