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 “内斗”余波:雷士照明附属及前董事吴长江遭提诉讼 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

若原油供应严重中断,仍可能会推高油价,但潜在的供应过剩会降低这种可能性。Saxo Bank的大宗商品策略部门主管汉森(Ole Hansen)说,新兴市场的需求曾使得供应如此紧张,因而任何一次供应中断都造成了油价的大幅波动。

阿姆斯特丹危机始于荷兰Seppenwolde银团对东印度公司的股价做出了巨额的反向下注。这只股票在1771年早已大跌,主要是因为孟加拉的损失。但这家公司靠借钱继续支付高股息,掩盖了问题。Seppenwolde深信东印度股价会很快反弹,基于保证金大举买入该股。但它的股价并未反弹,在东印度公司降低了股息后,股价甚至进一步走低。

BROADCHURCH (BBC America, March 4) David Tennant returns in the second season of this evocative British mystery, playing Detective Alec Hardy again (after a season as Detective Emmett Carver in the American remake, “Gracepoint”). With the British premiere scheduled for Monday, the producers have begun to talk a little about the show’s top-secret Season 2 story line, and fans may not like what they hear: Chris Chibnall, the creator and writer, told a British magazine, “It’s not another crime case.” Olivia Colman returns as Detective Ellie Miller, while Charlotte Rampling and Marianne Jean-Baptiste join the cast.

"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.

James Gorman, a Times reporter, accompanied scientists who are trying to understand the genes that distinguish dogs from wolves. Humans who raise wolf puppies must spend 24 hours a day, seven days a week with them in order to socialize these puppies for scientific study. And while the pups may seem cute, they will grow to be predatory wolves, not humanity’s faithful companions. The researchers hope their work will help reveal the trigger that made some ancient wolves into the dogs we know today.

In one example, Christie’s was offering the mid-18th-century canvas “Rebecca and Eliezer at the Well” by the Venetian artist Francesco Fontebasso at a low estimate of 120,000. The pleasant piece of rococo decoration had been bought at auction in 1990 for $286,000, according to Artnet. At the Dec. 8 sale it fell to a single telephone bid of 115,000, about $170,000, before fees. Investors do not expect to incur a loss of about 40 percent a quarter century after buying a Warhol or a Basquiat. Reselling an old master can be even harder when that painting has been languishing in a dealer’s gallery.

A lot of the best James Bond theme songs sound like they belong in a lounge act. That's not a complaint, just an observation. For whatever reason, the English new wave act Duran Duran was given free reign to provide A View to a Kill with a new and exciting sound all its own. "A View to a Kill" was a hit song, and it probably would have been a success even without the James Bond connection. It's entertaining and cool and energetic, and it promises one hell of a good time. (Whether or not the movie actually lives up to that promise is a matter of some debate.)
