Researchers largely agree that about half of Americans are probably not getting enough vitamin D from the places we've traditionally gotten it: food and sunlight. And that's a problem because vitamin D keeps calcium from leaking out of our bones; too little vitamin D can also be a factor in kidney disease and skeletal problems.
A boat skims through the melting ice in the Ilulissat fiord, on the western coast of Greenland, in 2008. The glacier is the most active in the Northern Hemisphere, producing 10 percent of Greenland's icebergs, or some 20 million tons of ice per day. But experts say the glacier is in bad shape because of climate change.

For better or worse, Microsoft has now shown its hand. The company Thursday showed off its new operating system, Windows 8, which will either mark a new era for the software giant in a hyper-competitive market, or spell its downfall.
Two states, Oregon and Washington, have legalized physician-assisted suicide through voter-approved ballot initiatives. Massachusetts will become the third if voters approve the so-called Death With Dignity ballot question.

No matter who wins the election on Nov. 6, official Washington will have to deal with something called the "fiscal cliff" before the end of the year.
What's coming is a perfect storm of expiring tax cuts, scheduled budget cuts, and various other spending changes scheduled to take place Jan. 1 unless Congress and President Obama (who no matter what will still be president until next Jan. 20) agree on a way to avert them.
These red, orange and green clouds (false color) in Saturn's northern hemisphere indicate the tail end of the massive 2010-2011 storm. Even after visible signs of the storm started to fade, infrared measurements continued to reveal powerful effects at work in Saturn's stratosphere.
But NASA scientists using the Cassini spacecraft have witnessed a rare massive storm on Saturn that was so violent it sent the temperature in the planet's stratosphere soaring to 150 degrees Fahrenheit above normal.
The presidential candidates may not be talking much about Guantanamo Bay, but the U.S. detention center there has been at the forefront of Michelle Shephard's mind for the last decade. The national security correspondent for the Toronto Star has traveled to Guantanamo Bay, Cuba, more than two dozen times; she even got enough stamps on her Guantanamo Starbucks card for a free latte.
The 2010 census brought some bad news for Niagara Falls, New York. Once one of the biggest cities in the Northeast, it has lost more than half its population since the 1950s. As Daniel Robison reports, Niagara Falls is now at risk of losing its city status, as well as million of dollars in federal aid.
DANIEL ROBISON, BYLINE: Niagara Falls residents shuffle into a town hall meeting. It's standing-room only in this small space.

A general view of the Aletsch Glacier on April 21, 2007, near Brig, Switzerland, the largest glacier in the Alps. Unseasonably warm weather with temperatures up to 77 degrees Fahrenheit across Switzerland let snow melt, even at Alpine altitudes.
Neither presidential candidate mentioned climate change during their three debates — in fact, the issue is nearly absent from the entire campaign. That's because the issue poses challenges for each candidate.
