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 广州今年入市商业体将达200万平方米 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

That pushed the state share of total investment for the year to date down marginally to 36.6 per cent, still the largest share since 2011 and reflecting the outsize role of government spending in sustaining economic growth during 2016.
His first coding effort resulted in an app that played audio snippets from speeches by his idol, Steve Jobs, whose unauthorized biography he'd recently devoured. 'It was rejected by Apple for every reason,' D'Aloisio says now, laughing. 'Copyrighted audio, poor functionality, too simple.' Another early design allowed users to touch a picture of wood, producing a knocking sound. A third transformed a smartphone screen into a treadmill for your fingers. That one earned about $120 in sales on its first day.

Fifteen Chinese nationals have been charged with developing a fraud scheme in which they paid imposters to take entrance exams, including the SAT, and gained acceptance to elite American colleges and universities, the US Department of Justice said on Thursday. Conspirators were paid up to $6,000 each time they used counterfeit Chinese passports to trick test administrators into thinking they were the person who would benefit from the test score, a federal grand jury charged.重点单词

"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.

Canadian border agents are handing people entering Canada a sheet from the Public Health Agency of Canada that instructs them to self-quarantine for 14 days and monitor themselves for any symptoms that might signal COVID-19. Selena Simmons-Duffin/NPR hide caption

To be sure, that excitement can certainly lead to unrealistic declarations from those in the community. Some bitcoin developers and investors proclaim that within five years, all the major banks will be accepting bitcoin. That’s a stretch, acknowledges Peter Smith, COO of the bitcoin wallet Blockchain (not to be confused with the actual bitcoin block chain). “I hear a lot of predictions about how soon the whole world will be using bitcoin, and most of the time, those are unrealistic,” he says. “What we’re trying to do as an ecosystem is incredibly audacious, so it’s going to take a lot of time.”

But researchers this year came up with a new method that makes flexible, realistic ears out of real cells. Those cells come from rats and cows, and they form a collagen gel that can take the shape of any mold. When placed in a mold of a human ear—a mold assembled using a 3-D printer—the gel forms an ear in less than an hour. The artificial ear then just needs a few days growing in nutrients before it's ready to be implanted in a subject.
