To stop the spread of the coronavirus, health officials have a favorite refrain: After being in a city or region where there have been a lot of COVID-19 cases, spend 14 days in quarantine even if you feel perfectly fine — don't leave your house. Coming from New York? 14-day quarantine. Arriving in Hawaii? 14-day quarantine. Been in Italy or China or Iran recently? 14-day quarantine.

"That's a long-standing public health practice, and it's called 'traveler's quarantine,' " explains Lindsay Wiley, a professor at American University's Washington College of Law. "Fourteen days is not a made-up number here — it's based on what we know so far about COVID-19, and it's possible that over time we'll see that number change as we learn more [about the virus]."

The 14-day rule is widespread because public health agencies around the world work together on these guidelines. In the U.S., the 城镇化建设将成建材企业“救命稻草” the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

《危险!》(Jeopardy!):这个游戏节目今年已播出50年(1964年3月30日首播),它证明自己不仅能难住观众,而且能令他们感到意外。不仅是因为主持人亚历克斯·特里贝克(Alex Trebek)留起了胡子(之前13年他都是把胡子剃得干干净净),而且是因为仍有些选手表明自己能刺激观众。今年刺激观众的是亚瑟·朱(Arthur Chu),他采用闪电战式的答题方式,在网上引起一片哗然。他的策略令人兴奋,当然也很奏效:他在锦标赛中夺得第二名(友善的本·因格拉姆[Ben Ingram]最后得了第一)。

The Harvard article suggests that protecting the brain with a heart-healthy diet could be the key to warding off dementia and keeping your memory intact well into your golden years. Some studies have suggested certain foods have a positive impact on memory, but no study thus far has revealed the existence of a miracle food. The idea that a heart-healthy diet could also prove beneficial to the brain and memory has become popular with doctors studying Alzheimer's disease and dementia. Some of the risk factors associated with heart disease are similar to those associated with dementia and Alzheimer's. Foods recommended for a heart-healthy diet include fruits, vegetables, and whole-grain bread, as well as beans, nuts, and olive oil. If you can't use every one of these 10 scientific secrets to a perfect memory, a healthy diet might help you avoid losing it!

"The incubation period varies from virus to virus and sometimes from host to host," says Rachel Graham, a virologist at the University of North Carolina's Gillings School of Global Public Health.

For the virus that causes COVID-19 — its official name is SARS-CoV-2 — researchers have found that the typical incubation period is about five days. About 97% of the people who get infected and develop symptoms will do so within 11 to 12 days, and about 99% will within 14 days.

Over the first weekend of 2015 the second-largest bitcoin exchange, Slovenia-based Bitstamp, was victim of a hack to the tune of some $5 million U.S. dollars’ worth of the digital currency. As the tech press were quick to point out, it was a worrisome start to the year for a digital currency that Quartz had already declared “the worst investment of 2014.” And if you look at its performance between Jan 1, 2014 and Jan. 1, 2015, that’s not wrong: bitcoin ended the year at 39% of the value it started with.

BABYLON (Sundance, Thursday) James Nesbitt, recently seen as the obsessed father of a long-vanished child in “The Missing,” shows up here in a very different role: as a calculating old-school police commissioner who hires an American public-relations expert (Brit Marling) to update the image of Scotland Yard.
