When McDonald's cut a deal to make itself the exclusive purveyor of french fries and the similar (but please don't say matching) chips at the 2012 Olympic Games in London later this month, it may not have anticipated the flurry of responses. Foodies raged, nutritionists nagged, and many called it another example of an American cultural takeover.
This is SCIENCE FRIDAY. I'm Ira Flatow. If you're out shooting hoops this summer or you're going for a jog, you know it won't be long before you're sopping wet and, you know, it's really sweaty out there. And where's all that sweat coming from? Your body's water supply, of course. You have to replenish those fluids if you sweat a lot. But it's not as simple as the old eight-glasses-a-day mantra. How much should you really drink? Too much water, you can die, as has happened to marathon runners who chugged too much water during the race.
Reporting in Science, two teams of scientists say they were unable to replicate the results of a 2010 study claiming to have found 'alien life' on Earth--a bacterium that could build its DNA using arsenic. Science journalist Carl Zimmer talks about how the controversy played out online, and how science corrects itself.
Reporting in the Bulletin of the American Meteorological Society, researchers write that extreme heat waves, such as the one last year in Texas, are 20 times more likely today than they were in the 1960s. NOAA climatologist Tom Peterson discusses what future climate change may bring.
California lawmakers gave the green light to the first phase of construction of high-speed rail in the state. Does this mean that America is on track for faster, sleeker trains? What potential speed bumps still lie ahead? Railroad engineer Christopher Barkan discusses the costs, benefits and state of the technology.
What makes some types of cancer resistant to drugs? Reporting in Nature, researchers write that cancer cells may be dodging treatment with help from seemingly innocent bystanders. Cancer researcher Todd Golub discusses how a tumor's microenvironment may affect its behavior.
Researchers have found a fridge-free way to store vaccines and antibiotics. Biomedical engineer David Kaplan, senior author of the study in the Proceedings of the National Academy of Sciences, discusses how heat-sensitive drugs wrapped in silk stay effective for months at high temperatures.
Imagine you're a movie producer, and you've got a couple of hundred million dollars to gamble on a single massive blockbuster. Which genre do you suppose will be your safest bet — superhero? Action-adventure? Sci-fi? All of those have had huge successes, but they've also all had hugely expensive failures.
There's one genre, though, that's hardly a gamble at all. It's been almost foolproof since it first came into being in 1995: computer animation.

In the absence of a cure or vaccine for HIV/AIDS, drug treatment has at least helped lower the pandemic's toll.
Since 2003, much of the treatment dispensed in hard-hit countries has come in the form of generic versions of previously expensive drugs. The President's Emergency Plan For AIDS Relief, or PEPFAR, has paid for quite a bit of the medicine.
