The next time you dab wasabi on your sushi or spread mustard on your hot dog, take a moment to thank a caterpillar. It may sound unlikely, but the critters play a critical role in creating the sharp, pungent flavors that give those condiments a savory kick.

The Supreme Court has placed a stay on a lower court's ruling that upheld new abortion standards in Texas, to give opponents of a controversial 2013 law time to take their case to the nation's highest court.

The stay is temporary: If the Supreme Court refuses to hear the case, the stay will be lifted and the law will take effect. If the justices agree to hear the case, the stay would remain in effect until a ruling is issued.

NBCUniversal is ending its business relationship with Donald Trump following comments Trump made about Mexican immigrants. Trump's controversial remarks came as he was announcing his bid for the Republican Party's presidential nomination.

It's T minus four days until exam day, and Travis Driscoll is practically living at his desk.

"Each day, I'm easily here for five hours," he says. "I haven't done much of anything else but studying for the last two months."

Driscoll is one of 13,000 medical school applicants across the U.S. taking the new Medical College Admissions Test, or MCAT. He's got stacks of science books on his desk to help him prepare and a rainbow of biochemistry charts pasted to the walls: glycolysis, citric acid cycle, electron transport chain, mitosis, meiosis and DNA replication.

The Supreme Court ruled last week that states cannot keep same-sex couples from marrying and must recognize their unions. The historic decision was welcomed by many, but there was much criticism, too, especially in some conservative states.

The world needs to count its girls!

That's the message that President Obama sent earlier this month when he signed the Girls Count Act into law. Congress had previously approved the act by unanimous vote.

There are 220 million children around the world who are uncounted. They were not registered at birth, and they don't have birth certificates.

In the longest leg of its planned around-the-world flight, the Solar Impulse took off from Nagoya, Japan, and is now headed to Hawaii. The plane is powered solely by the sun's energy that's stored in batteries; the current trip is expected to last 120 hours — five days and five nights.
