Runners clutching bottles of energy drink are a common sight, and it has long been known that sugary drinks and sweets can significantly improve athletes' performance in endurance events. The question is how? 

Clearly, 'sports' drinks and tablets contain calories. But this alone is not enough to explain the boost, and the benefits are felt even if the drink is spat out rather than swallowed. Nor does the sugary taste solve the riddle, as artificial sweeteners do not boost performance even when they are indistinguishable from real sugars.

The threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to a new analysis. 

While global temperatures would rise, the most dangerous potential aspects of climate change, including massive losses of Arctic sea ice and permafrost and significant sea-level rise, could be partially avoided.

"This important study, when taken with similar efforts, will help define a major challenge for society," says Cliff Jacobs of NSF's Atmospheric Sciences Division.

The benefits of physical activity and a balanced diet are well documented and form the basis of many public health recommendations; this is because each of these factors can independently influence risks for many chronic diseases such as obesity, type 2 diabetes, and some forms of cancer.

Some research also suggests that exercise and diet interact to influence health. For instance, exercising after short-term fasting (such as before breakfast) may increase the amount of fat burned. Similarly, consumption of a meal eliciting a low blood glucose response prior to exercise may also boost the use of body fat (instead of glucose).

Researchers say they have uncovered new evidence suggesting factors other than genes could cause obesity, finding that genetically identical cells store widely differing amounts of fat depending on subtle variations in how cells process insulin.  Findings indicate that the faster a cell processes insulin, the more fat it stores.

Learning the precise mechanism responsible for fat storage in cells could lead to methods for controlling obesity.  

I was inadvertently exposed to the filth and depravity of VH1's "Rock of Love Bus," also known as STDs on Wheels, when I turned on my TV to watch the (relatively) innocent and science-fueled Big Bang Theory.

If you feel like dropping 150 IQ points, here's the clip in all its intellectual and classy glory. If you don't have any neurons to spare, here's a quote that sums up the few minutes' worth of the show I saw (and that's all I ever want to see), as Bret Michaels expresses his heartfelt emotions with lyricism inspired by the deep wells of pure love: "You are this rocking hot centerfold, ok?"

Molecular anthropology—you probably haven’t heard of this discipline by name but I guarantee that you already find this particular field fascinating.  Therefore, I’d like to formally introduce to you the field of molecular anthropology which includes such areas of research as; genetically reconstructing man’s ancient migration from Africa to the Americas, resurrecting Neanderthal genomes and identifying ancestral origins through DNA ancestry.

"Wash that for you?" If you were a fish living in the warm turquoise waters off the coast of Bonaire, you may not hear those words, but you'd see the shrimp sign language equivalent. It seems Periclimenes yucatanicus or Spotted Cleaner Shrimp is doing a booming business in the local reefs by setting up a fish washing service.
