If you're taking vitamins to guard against cancer or a heart attack, you've got plenty of company.

Nearly half of American adults take a vitamin of some kind each a day. About a third take a multivitamin.

But are they worth it?

For people in good health and without any special nutritional deficiencies, there isn't enough evidence to say it's a good idea — at least when it comes to preventing cardiovascular disease and cancer.

Colorado Becomes First State To Restrict Methane Emissions

Originally published on Tue February 25, 2014 7:06 am

Methane is a potent greenhouse gas from oil and gas production. The rules require companies to find and repair equipment leaks. The rules also will reduce air pollution that contributes to smog.

Scientists have gotten close to pinning down the origin of Middle East Respiratory Syndrome, a dangerous respiratory disease that emerged in Saudi Arabia 17 months ago.

It turns out the MERS virus has been circulating in Arabian camels for more than two decades, scientists report in a study published Tuesday.

So far MERS has sickened more than 180 people, killing at least 77 of them — an alarming 43 percent. But scientists haven't been sure where the virus came from or how people catch it.

Industry Challenges EPA's Greenhouse Gas Rules In High Court

Not all energy producers find fault with the EPA's rules. Calpine, which helped build the Delta Energy Center in Pittsburg, Calif., says the permitting regulations aren't overly cumbersome.

The Supreme Court will hear arguments Monday about the Environmental Protection Agency's first-ever greenhouse gas regulations for the biggest polluting facilities.

The case focuses on a 3-year-old requirement that companies get permits anytime they construct new plants or modify existing ones that will emit a lot of greenhouse gases.

EPA's supporters and most of its challengers agree this case is narrow in scope; the court's ruling is not expected to threaten EPA's broader strategy to fight global warming.

Originally published on Mon February 24, 2014 1:06 pm

Scientists have used a powerful new technique to prove that some tiny crystals found in Western Australia are indeed the oldest known materials formed on Earth.

Back in 2001, scientists reported that one of the zircon crystals was about 4.4 billion years old — so old that not everyone believed it.

"There have been challenges, because nothing in science goes without being questioned. It always has to be proven," says John Valley, a geochemist at the University of Wisconsin, Madison.

NWS Confirms 4 Tornadoes Hit Alabama

National Weather Service

The National Weather Service says at least four tornadoes touched down in Alabama during this week's storms, including an EF-2 tornado that flung a semitrailer onto the roof of an industrial plant in the Fort Payne area.

The Fort Payne-area twister was brief but powerful, with estimated winds up to 125 mph. Survey crews from the weather service say it flipped three large semitrailers, vaulting one into the air and onto the factory's roof around 12:30 a.m. Friday.

January will go down in the weather history books as the fourth-warmest on record.

That's right.

No matter how brutal the winter was in North America, especially the Eastern half, it was balanced by warm temperatures elsewhere on the planet.

The National Oceanic and Atmospheric Administration's National Climate Data Center says that last month marks the 38th consecutive January and the 347th consecutive month (almost 29 years) that global temperatures have been above the average for the 20th century.

A paw on the leg. A nose nuzzling against your arm. Maybe even a hop onto your lap.

Dogs always seem to know when you're upset and need extra love, even though they hardly understand a word of what you say. How can that be?

Our four-legged friends have a little patch of their brain devoted to deciphering emotions in human and dog voices, scientists reported Thursday in the journal Current Biology.

Are More Eccentric Artists Perceived As Better Artists?

Originally published on Fri February 21, 2014 8:29 am

Transcript

STEVE INSKEEP, HOST:

Think for a moment about an artist who is really out there in some way. Maybe a musician comes to mind, somebody like Lady Gaga or a painter like Salvador Dali. New research now asks whether you like such artists because of their art or because they conform to a mental stereotype of how artists are supposed to behave. NPR's social science correspondent Shankar Vedantam joins us regularly on this program. Hi, Shankar.

SHANKAR VEDANTAM, BYLINE: Good morning, Steve.
