Whether it's jet lag, a new work schedule, daylight saving time or just a Monday morning, shifting sleep schedules takes a toll. But scientists think they might have found a way to reset our internal timers that's more than hot air.

At least, it works if you're a mouse. The solution, it seems, is thin air. A study published Thursday in the journal Cell Metabolism found that decreasing oxygen levels for a short period of time helped mice recover from jet lag faster.

Giant panda Bao Bao, born at the National Zoo in Washington, D.C., in August 2013, will be heading to China this winter.

Bao Bao's parents, Mei Xiang and Tian Tian, are on loan from China, and the agreement calls for any pandas born to the breeding pair to be sent to the Chinese breeding program before they turn 4.

On a blistering 90-degree day, Nelly Carrillo stands over her stove, placing a chorizo and potato sope onto the oiled cast-iron skillet. The thick, fried tortilla sizzles, and she wipes sweat off her brow with the back of her softly wrinkled hands. You can hear a cacophony of honking cars and voices in the near distance.

As Donald Trump and Hillary Clinton shook hands with moderator Chris Wallace and greeted their families after the end of Wednesday night's presidential debate, the broadcast hosts delivered their verdict.

"All six of the 15-minute segments — total home runs for him," said Cliff Sims. "I think this was really the performance that Donald Trump needed to grab that momentum going toward the election."

His co-host, Boris Epshteyn, agreed: "He prosecuted the case against Hillary Clinton perfectly."

Huang Xian'er came of age while watching Internet celebrities' streaming videos on her smartphone in western China's Yinchuan city.

"My mom knew I was watching Internet stars in school," she recalls. "She simplistically thought that all Internet stars sell clothes, get plastic surgery and all look the same."

A guy who covers agriculture in the West who's never put a skinned, sliced, battered, deep-fried bull testicle into a cup of cocktail sauce and then into his mouth?

I couldn't let it stand.

They're known by many names: lamb fries, bull fries, Montana tenders, huevos de toro, cowboy caviar. In my corner of Colorado, they're Rocky Mountain oysters, and I somehow coaxed myself into thinking I needed to try them to be more a part of the place I live, to be a true-blue Coloradoan.

Dorothy's ruby slippers could use a little more magic these days — or at least some preservationist TLC.

The famous shoes from The Wizard of Oz are among the most popular items on display at the Smithsonian's National Museum of American History. But they're showing their age, and the museum is asking the public to pitch in to help keep the shoes intact for decades to come.

Just 18 and still in high school, Camila Rodriguez did not feel prepared for motherhood when she learned she was unexpectedly pregnant. She began asking around her school, hoping to find someone selling Misoprostol, a pharmaceutical drug that treats stomach ulcers, but which has been banned in Chile since 2001 because it can also induce abortions.

In the final presidential debate, Donald Trump said he supports the federal ban on "partial-birth" abortion because, under the procedure, "in the ninth month you can take the baby and rip the baby out of the womb of the mother."

He added that this can happen "as late as one or two or three or four days prior to birth."

But that is not at all likely.
