Supreme Court Rules In Industry's Favor. What's EPA's Next Move?

The U.S. Supreme Court ruled Monday that the Environmental Protection Agency made a mistake when it told electric power plants to reduce mercury emissions. The high court says the EPA should first have considered how much it would cost power plants to do that.

Supreme Court Places A Stay On Abortion Law In Texas

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.

A cabbage butterfly caterpillar. For tens of millions of years, these critters have been in an evolutionary arms race with plants they munch on. The end result: "mustard oil bombs" that also explode with flavor when we humans harness them to make condiments.

Why You Should Thank A Caterpillar For Your Mustard And Wasabi

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 U.S. Now Has A 'Girls Count' Law. But Don't Boys Count, Too?

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.

NBC said in a statement that:

Bite into that bread before your main meal, and you'll spike your blood sugar and amp up your appetite. Waiting until the end of your dinner to nosh on bread can blunt those effects.

Curb Your Appetite: Save Bread For The End Of The Meal

Ah, the bread basket. You sit down for a nice meal out, and there it appears: piping hot, giving off a waft of yeasty divinity.

Who can resist?

There's a reason this age-old tradition prevails. Even in the era of paleo and gluten-free, there are still hordes of us who will gladly nosh on crusty, chewy, soul-warming bread.
