“Like armies everywhere, the German military is filled with macho, chest-thumping rituals. But one battalion has found there’s a downside to all that chest-thumping: The male soldiers are growing breasts — and only on their left sides.
The Wachbataillon unit performs precision military drills at official ceremonial functions, the German Herald reports. Many of their drills involve smacking their rifles against the left side of the soldiers’ chests. And all that pounding on the same spot has stimulated the production of hormones that cause man boobs to grow.”
The science of dropping your food on the ground reveals surprising lessons in this video from the hit YouTube science series Vsauce (1 million subscribers and counting). The show’s founder and host, Michael Stevens, set out to verify the five-second rule, citing research in The Journal of Applied Microbiology and investigations by others, including Mythbusters, to break the bad news (spoiler alert) that it’s no good. ”Five seconds is way too long to wait,” he warns; “bacteria adhere to dropped food almost immediately.” But wait! There’s more. Watch the video below to learn how the structure of molecules makes things sticky and why you’re about one pound heavier after stepping out of the shower.
“Particularly when you’re older, you are 14 percent more likely to die on your birthday than on any other day of the year. Particularly when you live in certain geographical areas, you are 13 percent more likely to die after getting a paycheck. And particularly when you’re human, you are more likely to die in the late morning — around 11 a.m., specifically — than at any other time during the day.
Yes. That last one comes from a new study, published in the Annals of Neurology, that identifies a common gene variant affecting circadian rhythms. And that variant, it seems, could also predict the time of day you will die.”
“Older men are more likely than young ones to father a child who develops autism or schizophrenia, because of random mutations that become more numerous with advancing paternal age, scientists reported on Wednesday, in the first study to quantify the effect as it builds each year. The age of mothers had no bearing on the risk for these disorders, the study found.”

Here is a photo of a 69-year-old man who drove a delivery truck for 28 years.
This—which is called Unilateral Dermatoheliosis—is the result of exposing onlyhalfof your face to direct sunlight for nearly three decades.
“Research shows that brushing too soon after meals and drinks, especially those that are acidic, can do more harm than good. Acid reflux poses a similar problem: While it might seem like a good idea to brush after a reflux episode, doing so can damage your teeth.
THE BOTTOM LINE
Never brush immediately after an acidic meal or drink. Always wait at least 30 minutes.”
We hate to say it, but policing thinspo on Pinterest won’t be easy. As Chavie Lieber reported a couple of weeks ago:
Exactly how Pinterest plans to monitor people’s pinboards, or differentiate between the harmful and the innocuous, is still unclear, especially since users themselves cannot agree on what is appropriate.
Pinterest’s new policy of taking down self-harm pins will be analyzed on a case-by-case basis, and only when pins are reported by fellow users. Offending pinners are notified when their content is removed, and they can then contact Pinterest with further questions or concerns.
Pills That Can Make You Smarter
Margaret Talbot writes for the New Yorker about the underground world of “neuroenhancing” drugs :
For the moment, people looking for that particular quick fix have a limited choice of meds. But, given the amount of money and research hours being spent on developing drugs to treat cognitive decline, Provigil and Adderall are likely to be joined by a bigger pharmacopoeia. Among the drugs in the pipeline are ampakines, which target a type of glutamate receptor in the brain; it is hoped that they may stem the memory loss associated with diseases like Alzheimer’s. But ampakines may also give healthy people a palpable cognitive boost. A 2007 study of sixteen healthy elderly volunteers found that five hundred milligrams of one particular ampakine “unequivocally” improved short-term memory, though it appeared to detract from episodic memory—the recall of past events. Another class of drugs, cholinesterase inhibitors, which are already being used with some success to treat Alzheimer’s patients, have also shown promise as neuroenhancers. In one study, the drug donepezil strengthened the performance of pilots on flight simulators; in another, of thirty healthy young male volunteers, it improved verbal and visual episodic memory. Several pharmaceutical companies are working on drugs that target nicotine receptors in the brain, in the hope that they can replicate the cognitive uptick that smokers get from cigarettes.
