Medical school might be a long, slow slog, but once doctors have their training, they can often make diagnoses in a matter of moments. New research suggests that doctors actually identify an abnormality in less than two seconds—not much longer than it takes them to name an animal or a letter of the alphabet.Twenty-five radiologists submitted to having their brains scanned while performing visual diagnoses of chest x-rays...
"It was the best of times, it was the worst of times"—Dickens's phrase might serve to sum up the reactions to what is now officially called the "Durban Platform for Enhanced Action" on climate change...

Nir Barzilai, a prominent researcher from the Albert Einstein College of Medicine in New York, read my story today on how a group of researchers from the Rush University Medical Center in Chicago had failed to replicate an earlier result from Barzilai's team that linked a particular gene variant to protection against dementia...
Researchers at the Massachusetts Institute of Technology (M.I.T.) have developed an imaging system that can acquire visual data at a rate of one trillion exposures per second--fast enough to produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bottle's bottom.As Ramesh Raskar, an associate professor in M.I.T.'s Media Lab, explains in the video below, a high-speed camera can capture the image of a bullet mid-flight...
The U.S. has been widely criticized in recent years for falling behind other developed countries in its deployment of high-speed wireless networks. The current dustup involving LightSquared, Bloomberg News and several government agencies provides some clues as to the complexity of the problem.LightSquared is proposing to build a high-speed nationwide 4G LTE (long-term evolution) network and lease capacity on that network to different wireless carriers, including Sprint Nextel Corp...
Students ages 14-18: Have a big idea for an experiment that can be done in space? Bring it! That is, describe it in a video and post it to YouTube Space Lab by December 14.
I have always been impressed by the design of the coffee grinder. Here you've got a supersharp metal blade spinning around in a buzzing blur and chopping the living bejesus out of those coffee beans...
