【人文科学-健康】 How to Clean Your Phone to Help Protect Against Coronavirus （383字 精读 必做篇）
The coronavirus is here, and it’s showing no signs of letting up. One of the best ways to protect yourself is to keep your hands clean and off your face, but it’s hard to maintain constant vigilance.
Keeping your phone sanitized is another smart way to keep germs off your fingertips. The Centers for Disease Control and Prevention considers your phone a “high-touch surface,” which could make it a carrier of the virus.
But cleaning your phone — thoroughly, I mean — is not as straightforward as it might seem. There are all sorts of nooks and crannies, delicate glass and intricate protective cases.
Any sort of moisture can interfere with your phone’s function. Apple recommends that people avoid using spray cleaners or heavy-duty products. No bleach, no aerosol sprays. You need your phone to work, even if you want it clean. Also — and this probably goes without saying — don’t dunk your phone into any sort of liquid, anti-bacterial or otherwise. It won’t end well for either of you.
A gentle wipe with a product that has 70 percent isopropyl alcohol will do just fine. Apple recommends Clorox Disinfecting Wipes, and the C.D.C. says household disinfectants registered by the Environmental Protection Agency are effective. Wear disposable gloves to clean, the C.D.C. recommends, and wash your hands thoroughly after you’re done. Like your phone, reusable gloves might harbor virus particles, rendering them effectively useless. And don’t forget your phone case.
You might also consider changing a bit of your behavior. AT&T suggests sharing photos through texts, instead of passing the phone around, and using devices like headphones and technology like Bluetooth to keep your phone away from your face.
This might be the best thing you can do all day. This outbreak is fast-moving and research is, by nature, slow to catch up. As a result, the C.D.C. does not yet know exactly how long the virus can cling to a surface, but evidence suggests it could be “hours to days.”
And phones are, well, gross. A 2017 study published in the journal Germs found a host of bacteria, viruses and pathogens on 27 phones owned by teenagers. The scientists wrote that they “hypothesize that this may play a role in the spread of infectious agents in the community.”
Safe is always better than sorry.

【人文科学-健康】 Gluten-Free Restaurant Foods Are Often Mislabeled （218字 1分38秒 精听 必做篇）
先做精听再核对原文哦~
A lot of restaurant menus these days have gluten-free options. Problem is, many of the dishes may not be gluten-free at all.
"About a third overall, 32 percent, of gluten-free-labeled restaurant foods had a gluten-found result." Benjamin Lebwohl, a gastroenterologist and epidemiologist at Columbia University.
His team got that 1/3 number by crowdsourcing data from 804 restaurant patrons, who used handheld gluten-testing devices to scan more than 5,600 restaurant food samples from across the U.S.
The devices can detect gluten at slightly lower levels than the maximum concentration the FDA allows for packaged foods—20 parts per million. So there could be some harmless false-positives in the data.
"But we suspect given that large proportion that this is clearly a bigger problem than in packaged food, where probably less than two percent of all packaged food has detectable gluten of greater than 20 parts per million."
The results are in The American Journal of Gastroenterology.
For those who need to avoid gluten for health reasons, Lebwohl has these tips.
"Food that was tested around dinnertime was more likely to have gluten detected than food earlier in the day." And avoid allegedly gluten-free pizzas and pastas, he says, which scored more violations than other dishes. More than half of all pizza and pasta dishes tested positive for gluten.
So a salad, for lunch, might be a safer bet.
