Animals, especially mammals, need oxygen to keep their bodies and brains humming along.

But leave it to the African naked mole-rat to buck that trend. The rodents are bizarre in just about every way. They're hairless, ground-dwelling and cold-blooded despite being mammals. Now, scientists report in the journal Science that the animals are capable of surviving oxygen deprivation.

When 18-year-old Nermeen Ileiwat first began college, she could not wait to get into a relationship — maybe even get engaged before graduation. But after one year, the rising sophomore realized she had no idea what she wanted out of life and was in no position to get into a relationship.

That decision didn't last long. Only a few months after, Ileiwat met someone at a party, and their friendship quickly turned into something more.

House Republicans are mulling over new changes to their health care proposal, hoping to wrangle enough votes to pass a bill that would allow them to keep their campaign pledge to repeal and replace the Affordable Care Act.

The latest proposal allows states to make changes to the ACA's rules governing health insurance policies and markets, in an effort to allow some states to offer stripped-down policies with lower premiums.

General Motors has stopped operations in Venezuela after its only plant there was illegally seized by authorities, the automaker says in a statement. The details are murky: Multiple employees at the plant tell NPR that they believe auto dealers, not government officials, were responsible for the takeover.

The seizure happened Wednesday, as the "mother of all protests" brought hundreds of thousands of people into the streets to demonstrate against socialist President Nicolas Maduro.

Beans, beans, the magical fruit

Healthy, tasty

And useful, to boot!

Save that canned water,

And whip it to foam

It's an egg-white replacement

Made right at home!

OK, so it's not the playground rhyme you grew up with. But with the avid following that canned bean water — more appetizingly known as "aquafaba" — has gained in just a few short years, maybe it's time that rhyme got rewritten.

The French go to the polls Sunday to cast ballots in the first round of a political race like no other in France's recent history: Entrenched politicians have been swept aside, with fringe candidates and untested newcomers filling the void.

After Sunday, the field of 11 presidential candidates will be narrowed down to two contenders, who will face each other in a runoff on May 7.

The top four candidates offer starkly opposing visions for the country. Yet they are so close in the polls that the race is impossible to predict.

People with a brain injury or dementia often struggle to remember simple things, like names or places. In research published Thursday in the journal Current Biology, scientists have shown it may be possible to improve this sort of memory using tiny pulses of electricity — if they're properly timed.

A typical person's ability to remember things tends to vary a lot, says Michael Kahana, who directs the computational memory lab at the University of Pennsylvania.

The United States spends the most on health care per person — $9,237 – according to two new papers published in the journal The Lancet.

Somalia spends the least – just $33 per person.

Marie da Silva is among the 25 percent of voters who are undecided ahead of Sunday's first round of voting in France's crucial presidential election.

The 52-year-old building manager and mother has soured on the men in the race, finding them too weak, unrealistic or communist.

Though she identifies as conservative, da Silva had never voted for the far-right party, National Front.
