Low carbon hemp house put to the test

A consortium in the UK has constructed a small building on a university campus out of hemp-lime to test its properties as a building material. Called the "HemPod", this one-storey building has highly insulating walls made from the chopped woody core, or shiv, of the industrial hemp plant mixed with a specially developed lime-based...

Facial recognition technology aimed at spotting terrorists

Rapid improvements in facial-recognition software mean airport security workers might one day know with near certainty whether they're looking at a stressed-out tourist or staring a terrorist in the eye. Researchers are evaluating how well these rapidly evolving recognition programs work. The researchers are comparing the rates of success for the software to the rates for non-technological, but...

New supercomputer 'sees' well enough to drive a car someday

Visually interpreting our environment as quickly as we do is an astonishing feat requiring an enormous number of computations -- which is just one reason that coming up with a computer-driven system that can mimic the human brain in visually recognizing objects has proven so difficult. Now a supercomputer based on the human visual system has been developed, operating much more quickly and...

BP's brand value sinks with oil spill this year (AP)

AP - BP may have plugged the leak in the Gulf Oil spill, but the damage done to its brand will take years to fix. A new marketing industry report released Wednesday shows the British oil company has tumbled off a list of the world's top 100...

105 days in isolation -- and counting -- for 400 more

Sailing now in interplanetary space on their simulated mission towards the ‘Red Planet`, the Mars500 crew has entered in a new phase of their isolation. The previous mission endured 105 days in 2009 and from now on, everything in this experiment is new.

Mild memory loss is not a part of normal aging

Simply getting older is not the cause of mild memory lapses often called senior moments, according to a new study by researchers at the Rush Alzheimer's Disease Center. The study, published in the September 15, 2010, online issue of Neurology, the medical journal of the American Academy of Neurology, found that even the very early mild changes in memory that are much more common in old age than...

New study examines how bacteria acquire immunity

In a new study this week, Rice University scientists bring the latest tools of computational biology to bear in examining how the processes of natural selection and evolution influence the way bacteria acquire immunity from disease.

New study finds milk drinkers may have a healthy weight advantage

Now there's a new reason to grab a glass of milk when you're on diet, suggests a new study published in the American Journal of Clinical Nutrition. In a 2-year weight loss study, milk drinkers had an advantage over those who skipped the milk. Israeli researchers found that adults who drank the most milk (nearly 2 glasses per day) and had the highest vitamin D levels at 6 months, lost more weight...

New wave: Spin soliton could be a hit in cell phone communication (w/ Video)

Researchers at the National Institute of Standards and Technology have found theoretical evidence* of a new way to generate the high-frequency waves used in modern communication devices such as cell phones. Their analysis, if supported by experimental evidence, could contribute to a new generation of wireless technology that would be more secure and resistant to interference than conventional...
