Even premature babies at 33 weeks post-conceptional age, about 2 months before term (40 gestational weeks), are capable of recognizing and distinguishing two objects of different shapes (a prism and a cylinder) with their right or left hands.

The CREST trial that compared traditional surgery with less-invasive stenting to clear dangerously clogged carotid arteries in the neck is being called "seminal and robust."

One laptop per child seems a simple slogan, chock full of benefit. What could go wrong when you put the power of the Internet and solar cells into the hands of children in the developing world? After all, not only does it train the global underclass in the tools of modern production, it also unleashes a creativity that may allow them to leapfrog the old, dirty, industrial development that has fouled the planet.

That's the sound of fracking --pumping a mix of water, sand and chemicals a mile or more into the Earth to shatter shale deposits and release the natural gas within.  

From the Barnett shale in Texas to the "supergiant" Marcellus shale that stretches from West Virginia to New York State, so much natural gas has been found that the U.S. may have enough to burn for 100 years or more. And burning natural gas releases 43 percent less CO2 than burning coal.

New research suggests a novel route to improving the symptoms of subsyndromal depression (SSD) in seniors through the regular use of "exergames" -- entertaining video games that combine game play with exercise. In a pilot study, the researchers found that use of exergames significantly improved mood and mental health-related quality of life in older adults with SSD.

A team of engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone, a biomass derivative, into the chemical equivalent of jet fuel.

Choking is a leading cause of injury and death among children, especially those younger than 4 years of age. The majority of choking-related incidents among children are associated with food, coins and toys.

Researchers have successfully removed CCR5 -- a cell receptor to which HIV-1 binds for infection but which the human body does not need -- from human cells. Individuals who naturally lack the CCR5 receptor have been found to be essentially resistant to HIV.

Ocean temperature patterns in the tropics and subtropics will change in ways that will lead to significant changes in rainfall patterns, according to new research.

Scientists have developed a method for analysing MR images (MRI) in just a few minutes when diagnosing Alzheimer's disease. The accuracy of the analysis is comparable to manual measurements made by skilled professionals, which are currently considered the most reliable method for diagnosing Alzheimer's disease. The accurate and rapid analysis method is well suited for clinical use.
