To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins.
Sudden cardiac death due to heart rhythm disturbances is blamed for more than 3,000 deaths a year in young people, especially [...]

A drug already approved for the treatment of lymphoma may also slow the growth of the most deadly bone cancer in children and teens, according to an early-stage study published online today in the International Journal of Cancer. The study drug, Bortezomib, was found to be effective against bone cancer in human cancer cell studies [...]

With less than half of patients with necrotizing soft tissue infections displaying the physical signs of these very serious infections, researchers have found two simple blood tests can help physicians diagnose what is commonly known as "flesh-eating bacteria," according to a study in the December issue of The American Journal of Surgery.
Researchers at the Los [...]

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated their ability to measure relatively low levels of stress or strain in regions of a semiconductor device as small as 10 nanometers across. Their recent results not only will impact the design of future generations of integrated circuits but also lay to rest [...]

Researchers at Children`s Hospital of Pittsburgh of UPMC have been able to effectively repair damaged heart muscle in an animal model using a novel population of stem cells they discovered that is derived from human skeletal muscle tissue.
The research team — led by Johnny Huard, PhD — transplanted stem cells purified from human muscle-derived blood [...]

ECG (electrocardiogram) tests commonly given to people with suspected angina to predict the likelihood future of heart disease have limited accuracy, according to a study published on the British Medical Journal website.
Alternative tests which add predictive value to that obtained from the patient`s clinical history are needed to improve the chances of detecting people at [...]

NASA has successfully tested the first deep space communications network modeled on the Internet.
Working as part of a NASA-wide team, engineers from NASA`s Jet Propulsion Laboratory in Pasadena, Calif., used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of space images to and from a NASA science spacecraft located about [...]

Cutting-edge “tweezers” are so sensitive that they can feel the tell-tale tug of tiny concentrations of pathogens in blood samples, yet don’t ever need to be sterilized—or even held—as they are ephemeral and weightless.
The National Institute of Standards and Technology (NIST) has licensed a patented “optical tweezers” technique for detecting and measuring very small concentrations [...]
