Every day, anestimated6,800 new peer-reviewed academic articles are published. That’s a whole lot of science to wade through—but don’t fret. We’ll do the legwork for you, each and every morning. Here’s your daily dose of the latest discoveries from journals, research institutions, and news outlets from around the world.
WHAT TESTOSTERONE’S DOING TO YOUR DECISIONS
Higher levels of testosterone may make guys make rash decisions, relying more on their impulses than on cognitive reflection, researchers from Caltech discovered. Men who received a dose of testosterone performed more poorly on a test of cognitive reflection, giving incorrect answers more quickly and right ones more slowly. “We think it works through confidence enhancement,” the researcher said in the news release. “If you’re more confident, you’ll feel like you’re right and will not have enough self-doubt to correct mistakes.” This raises questions of whether testosterone supplementation can mess with your decisions, too.
BEWARE THE MAN BUN?
A new hairstyle for guys might be messing with their hair: Man buns are causing an increase in traction alopecia, a type of hair loss caused by prolonged tension on the hair in your scalp, according to Dermatology News. Continually pulling your hair back tightly can actually cause your hairline to recede.
“BE FAST” WHEN IT COMES TO STROKE
The acronym BE FAST can help you recognize a stroke and act quickly, so you can receive treatment to minimize its damaging effects, according to NewYork-Presbyterian Hospital. Check for a sudden loss of Balance, sudden loss of vision in one or both Eyes, an uneven Face droop, sudden Arm weakness, and sudden slurred Speech. Time is critical, so call 911 immediately.

GET A YEARLY FULL-BODY SCREENING?
Currently, there is not a national consensus on whether we should be receiving yearly, full-body exams to check for skin cancer. But one group of dermatologists and oncologists think there should be, at least for those who are considered “high risk,” as they report in the journal FutureMedicine. This includes a history of melanoma, actinic keratosis, non-melanoma skin cancer, genes that put them at risk, if they are immunocompromised, have a family history of melanoma, certain physical features like light skin, blonde or red hair, more than 40 moles, two ore more atypical moles, many freckles, or sun-damaged skin, a history of blistering or peeling sunburn, or a history of indoor tanning.
END IMPAIRED DRIVING
Think alcohol alone is the cause of most fatal car crashes? Not so: Drugs were present in 43 percent of fatally injured drivers—appearing more frequently than alcohol, according to a new report from Governors Highway Safety Administration. As more and more states are legalizing marijuana—and record numbers of people are dying from drug overdoses—it raises the importance of tackling impaired driving as a problem that’s not just alcohol-driven.
