There is evidence that co-infection of Helminth worms may result in a more rapid progression of HIV infection to AIDS. Does treating these worms ("de-worming") slow down this progression? In a new study published in PLoS Neglected Tropical Diseases, researchers set out to answer this question. Their study found that there were simply not enough data to make any firm conclusions, and they call for larger, well-designed studies to help come to a definitive answer.
Youngsters who are allowed to leave the house without an adult are more active and enjoy a richer social life than those who are constantly supervised, according to a study conducted at UCL and reported in a special edition of the journal Built Environment (Dec. 19).
No human can survive longer than a few minutes underwater, and even a well-trained Olympic swimmer needs frequent gulps of air. Our brains need a constant supply of oxygen, particularly during exercise.
Contrast that with Weddell seals, animals that dive and hunt under the Antarctic sea ice. They hold their breath for as long as 90 minutes, and remain active and mentally alert the whole time. The seals aren't fazed at all by low levels of oxygen that would cause humans to black out. What's their secret?
A study of Vietnam war veterans who suffered brain injuries during the conflict has found that the men show a faster decline in their cognitive functioning as they grow older than veterans without such injuries.
Four Virginia Tech engineering science and mechanics students have completed "Surf Green" for their senior design project, and conclude that they can technically improve the surfboard's performance.
Harry Potter may not have talked much about plasmonics in J. K. Rowling's fantasy series, but University of Maryland researchers are using this emerging technology to develop an invisibility cloak that exists beyond the world of bespectacled teenage wizards.
Bypassing decades-old conventions in making computer chips, engineers developed a novel way to replace silicon with carbon on large surfaces, clearing the way for new generations of faster, more powerful cell phones, computers and other electronics.
A team of Vanderbilt researchers have demonstrated for the first time that a new type of gene therapy, called RNA interference, can heal a genetic disorder in a live animal.
Researchers at the University of Texas Medical School at Houston have discovered an association between genes regulating glucose metabolism and spina bifida. The decade-long study looked at more than 1,500 DNA samples from parents and their children with that birth defect.
NASA has given a University of Maryland-led team of scientists the green light to fly the Deep Impact spacecraft to Comet Hartley 2 on a two-part extended mission known as EPOXI. The spacecraft will fly by Earth on New Year's Eve at the beginning of a more than two-and-a-half-year journey to Hartley 2.
