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.

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.

Billionaire Steyer Puts Money Toward Climate, Energy Issues

Originally published on Mon February 24, 2014 7:34 am

DAVID GREENE, HOST:

OK. So in the words of that political scientist in Peter's piece, wealthy donors like Tom Steyer are putting a pistol to someone's head, forcing their pet issues on candidates. Steyer himself sees things very differently. He quit his hedge fund with $1.5 billion and now in his view he's fighting as hard as he can with money and passion to do something very noble - save the planet. When he sat down to speak with us he said his goal is to use his money to limit carbon emissions.

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.

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.
