Changes to the acidity of the Earth's ancient oceans affected the coral reefs more than 50 million years ago. And researchers are using that information to try to predict how the planet might fare in our rapidly changing climate. Above, the Wheeler Reef section of the Great Barrier Reef.
One of the most powerful ways to figure out how the Earth will respond to all the carbon dioxide we're putting into the atmosphere is to look back into the planet's history.
Paleontologists have spent a lot of time trying to understand a time, more than 50 million years ago, when the planet was much hotter than it is today. They're finding that the news isn't all bad when you take the long view.
Imported food is getting the kind of attention these days that no product wants. Health officials in Iowa and Nebraska are blaming salad greens for making hundreds of people sick with a parasite called cyclospora. That parasite usually comes from the tropics, so it's likely the salad did, too. Earlier this summer, pomegranate seeds from Turkey were linked to an outbreak of hepatitis A.

Buzz, Georgia Tech's mascot, wasn't the only bug in the students' midst last fall. An outbreak of bacterial pneumonia sickened at least 83 in what the CDC called the largest known outbreak at a university in 35 years.

You can lead college students to soap and water, but you can't make them wash their hands. In fact, you can't even make them read their e-mail.
That was one takeaway from an outbreak of pneumonia at Georgia Tech last fall that sickened at least 83 students – "the largest [outbreak] reported at a university in 35 years," according to the Centers for Disease Control and Prevention.

Government regulators in Canada are investigating a series of mysterious oil spills around tar sands operations in Alberta. Thick oil is gurgling up unexpectedly from the ground instead of flowing through the wells that were built to collect it.
The spills are raising questions about a technology that's rapidly expanding to extract fossil fuels that could ultimately end up in the controversial Keystone XL pipeline.

Whenever we give in to temptation, be it for a helping of something divine, like fine chocolate, or just a so-so piece of saltwater taffy abandoned next to the office coffeepot, there's something more than self-control at work.
Woven into the complexities of food choices and eating behaviors are all sorts of subtle factors that we're likely not even aware of.

Rarely is the relationship between science and everyone so direct as it is in the case of genetically modified organisms (GMOs), in particular foods. It is one thing to turn on your plasma TV or talk on your iPhone; it is an entirely different proposition to knowingly ingest something that has been modified in the lab.
