Now, a story about heat, the sweaty, miserable kind. Heat plus humidity. Working outdoors or playing sports on a hot, muggy day can be dangerous, even deadly. And as the climate continues to warm, being outside will become even more challenging. Those are the findings of a new study in the journal Nature Climate Change.

The remains of a small continent have been hiding right under our noses for the past 85 million years or so.
That's according to a new study published Sunday in the journal Nature Geoscience. Scientists looked at lava sands from beaches on Mauritius to determine when and where the material might have originated.

Pour on the olive oil in good conscience, and add some nuts while you're at it.
A careful test of the so-called Mediterranean diet involving more than 7,000 people at a high risk of having heart attacks and strokes found the diet reduced them when compared with a low-fat diet. A regular diet of Mediterranean cuisine also reduced the risk of dying.
The findings, published online by The New England Journal of Medicine, come from a study conducted right in the heart of Mediterranean country: Spain.

The worst environmental disaster in American history is the subject of a trial that is beginning today. It's a big and complicated civil lawsuit stemming from the 2010 explosion of the Deepwater Horizon oil rig in the Gulf of Mexico - and, of course, the spill that followed that.

Prehistoric humans didn't have toothbrushes. They didn't have floss or toothpaste, and they certainly didn't have Listerine. Yet somehow, their mouths were a lot healthier than ours are today.
"Hunter-gatherers had really good teeth," says Alan Cooper, director of the Australian Centre for Ancient DNA. "[But] as soon as you get to farming populations, you see this massive change. Huge amounts of gum disease. And cavities start cropping up."
The meteor that caused at least 1,000 injuries in Russia after a startling and powerful daytime explosion one week ago has been identified as a chondrite. Russian scientists who analyzed fragments of the meteor, whose large size and well-documented impact made it a rarity, say that its composition makes it the most common type of meteor we encounter here on Earth.
Scientists searching for invasive species in Lake Tahoe scooped up a bright orange goldfish measuring nearly a foot and a half long and weighing more than 4 pounds, according to the website Live Science. (You can see it here.)
Environmental scientist Sudeep Chandra says a survey has uncovered a "nice corner" of the lake where about 15 other giant goldfish were living, apparently after being dumped there by aquarium owners.

Economists at the U.S. Department of Agriculture, gazing into their crystal ball, see American farmers planting and harvesting huge amounts of corn, soybeans, and wheat this year. They're predicting a record harvest of corn: 14 billion bushels, up nearly 40 percent over last year's drought-crippled level.
With supply up, prices will fall. The USDA thinks that the price of the average bushel of corn could fall by a third. And soybean production and price are expected to follow a similar track.
In Fairbanks, Alaska, residents are using wood stoves to heat their homes during the frigid winter months. But, smoke created by these wood burners is contributing to some of the worst air pollution in the country. Cathy Cahill discusses air quality in the Last Frontier.
