In the largest study of its kind, surgeons at Hospital for Special Surgery have determined that by modifying a classic ligament surgery, they can return more athletes, such as baseball players, to their prior level of competition. The modified surgery repairs a torn medial collateral ligament (MCL), which links and stabilizes bones of the lower and upper arm where they meet at the elbow. 

Less traumatic than the classic Tommy John surgery, the modified surgery called the docking procedure, with time, is likely to become the gold standard for treating these injuries.

A national survey of commercial health plans has found that most plans provide online information regarding mental health and substance abuse but few provide clinical services such as counseling via the Internet. The nationally representative health plan survey, published in Psychiatric Services, and led by Dr.

Researchers have taken advantage of the unique coupled semiconducting and piezoelectric properties of zinc oxide nanowires to create a new class of electronic components and devices that could provide the foundation for a broad range of new applications.

So far, the researchers have demonstrated field-effect transistors, diodes, sensors – and current-producing nanogenerators – that operate by bending zinc oxide nanowires and nanobelts.

Using a state-of-the-art technique to map neurons in the spinal cord of a larval zebrafish, Cornell University scientists have found a surprising pattern of activity that regulates the speed of the fish's movement.

Researchers at Harvard, Gray et al, are conducting an ongoing mind survey, and have also reported some findings from that online survey, based on a sample of more than 2,000 people. The survey attempts to make one think about different forms of entities that may have a mind and to assign different degrees of consciousness/ mind to them.

The Altair 8800, introduced in the early 1970s, was the first computer you could build at home from a kit. It was crude, didn't do much, but many historians would say that it launched the desktop computer revolution.

Hod Lipson, Cornell assistant professor of mechanical and aerospace engineering, thinks a little machine he calls a Fab@Home may have the same impact.

Drinking whole fat milk and eating ice cream appears to be better for women trying to become pregnant than a diet consisting of low-fat dairy products such as skimmed milk and yoghurt, according to new research published in Europe's leading reproductive medicine journal, Human Reproduction, today (28 February). [1]

Researchers in the United States have found a link between a low-fat dairy diet and increased risk of infertility due to lack of ovulation (anovulatory infertility). Their study showed that if women ate two or more servings of low-fat dairy foods a day, they increased their risk of ovulation-related infertility by more than four fifths (85%) compared to women who ate less than one serving of low-fat dairy food a week.

Digital atlases of the brains of humans, monkeys, dogs, cats, mice, birds and other animals have been created and posted online by researchers at the UC Davis Center for Neuroscience.

BrainMaps.org features the highest resolution whole-brain atlases ever constructed, with over 50 terabytes of brain image data directly accessible online. Users can explore the brains of humans and a variety of other species at an unprecedented level of detail, from a broad view of the brain to the fine details of nerves and connections. The website also includes a suite of free, downloadable tools for navigating and analyzing brain data.

Scientists were startled when they discovered in 2004 that the center of our galaxy is emitting gamma rays with energies in the tens of trillions of electronvolts.

Now astrophysicists at The University of Arizona, Los Alamos National Laboratory and the University of Adelaide (Australia) have discovered a mechanism that might produce these high-energy gamma rays.
