The Schiaparelli Mars lander got very close to the red planet before something went wrong. It entered the planet's atmosphere, managed not to burn up as it hurtled down and unfurled its parachute. It's unclear what happened in the final minute of descent, but it wasn't what the European and Russian space agencies had planned.

The British government announced Wednesday that it intends to posthumously pardon thousands of men convicted for consensual sexual relationships with other men.

A proposed amendment dubbed the "Turing Law" was announced by the U.K.'s Ministry of Justice in a press release that said it would "build on the case of Enigma codebreaker Alan Turing, who committed suicide following his conviction for gross indecency."

In front of an exuberant crowd Thursday in Delaware, Ohio, Donald Trump again addressed whether he would accept the outcome of the November election.

"Ladies and gentleman I want to make a major announcement today," Trump said, continuing, "I would like to promise and pledge to all of my voters and supporters, and to all of the people of the United States, that I will totally accept the results of this great and historic presidential election ..."

After weeks of anti-U.S. rhetoric that included denunciations of President Obama, Philippine President Rodrigo Duterte has announced "I have separated from them," using his remarks during a state visit to China to seek closer ties with that country.

Snakes used to wander the Earth on legs about 150 million years ago, before they shifted from strut to slither.

Now, two scientists have pinpointed the genetic process that caused snakes to lose their legs. What's more, they say the "molecular machinery" for leg development still persists in snakes after these millions of years — it's simply switched off.

Unexplained fainting episodes may be caused by a dangerous blood clot in the lung more frequently than many doctors suspect, according to an Italian study.

Episodes of fainting (known as syncope) are quite common in elderly people. About half the time, doctors identify an underlying heart condition. Other cases are caused by shock or some other passing cause. But many cases remain mysterious.

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.

Remember the California drought? It was all over the news a year ago, when the state took the unprecedented step of mandating statewide water cutbacks. The Sierra Nevada snowpack was at its lowest recorded level. Rivers and reservoirs were getting shallower and shallower. Wells in rural towns were literally running dry.

That drought is still very much a thing.

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."
