(PHILADELPHIA) Publishing in PLoS Pathogens, researchers at from the Kimmel Cancer Center at Jefferson have found a novel mechanism by which drugs block HIV-1 from entering host cells.
A team of scientists from The Forsyth Institute, the University of Connecticut Health Center, the CDC and the Wadsworth Center, have used state-of-the-art technology to elucidate the molecular architecture of Treponema pallidum, the bacterium which causes syphilis. The previously unknown detailed structure of the bacteria can now be shown in three dimensions.
PITTSBURGH -- A University of Pittsburgh team overcame a major hurdle plaguing the development of nanomaterials such as those that could lead to more efficient catalysts used to produce hydrogen and render car exhaust less toxic. The researchers reported Nov.
New Orleans, LA -- Researchers from LSU Health Sciences Center New Orleans School of Public Health, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), Harvard School of Public Health, Brigham and Women's Hospital, and Harvard Medical School, have found for the first time that drinking more than 5 servings of sugar- sweetened cola a week prior to pregnancy
There is a tiny period of time between the registration of a visual stimulus by the unconscious mind and our conscious recognition of it ? between the time we see an apple and the time we recognize it as an apple. Our minds lag behind our eyes, but by how long? And how does this affect our reactions to the world around us?
After nearly two years of development and extensive discussion in the scientific community, the Institute for Quality and Efficiency in Health Care (IQWiG) presents its methods for evaluating the relation between cost and benefit. The Institute can now apply these methods when working on certain commissions awarded by the Federal Joint Committee (G-BA).
The Naval Research Laboratory's Ion Tiger, a hydrogen-powered fuel cell unmanned air vehicle (UAV), has flown 26 hours and 1 minute carrying a 5-pound payload, setting another unofficial flight endurance record for a fuel-cell powered flight. The test flight took place on November 16th through 17th.
Toronto, Ont., November 30, 2009 ? Providing free medications to people after heart attack could add years to patients' lives at a relatively low cost for provincial governments, according to a new study by researchers at St. Michael's Hospital in Toronto.
Nida is still holding on to Super Typhoon status in the Western Pacific Ocean, and over the weekend, is forecast to pass east of both Iwo To and Chichi Jima islands. Although the center of Nida will remain at sea, both islands will face heavy surf, gusty winds and heavy rainfall.
Researchers at Uppsala University and University Children's Hospital in Uppsala have devised powerful new tools for typing cells from children with acute lymphatic leukemia and for prediction of how children with leukemia will respond to chemotherapy. The study was recently published in electronic form by the prestigious hematological journal Blood.
WASHINGTON -- NASA's Fermi Gamma-ray Space Telescope has made the first unambiguous detection of high-energy gamma-rays from an enigmatic binary system known as Cygnus X-3. The system pairs a hot, massive star with a compact object -- either a neutron star or a black hole -- that blasts twin radio-emitting jets of matter into space at more than half the speed of light.
A short time ago, Swedish scientists published a paper suggesting the existence of a genetic disposition to respond to placebo, thus giving rise to debate in the media about a possible "placebo gene." In the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2009; 106[46]: 751????), Matthias Breidert and Karl Hofbauer summarize the most recent data about placebos.
The Aznalcóllar mining accident more than 11 years ago, which contaminated part of the Doñana National Park, also damaged reptile habitat there. Now a team of Spanish researchers, who have been studying the reptile community since 2000, have shown, by setting up artificial refuges, that the disappearance of natural refuges had a serious impact on lizard and snake numbers.
The first-ever Australian benchmark of climate change impacts on marine ecosystems and options for adaptation is being released in Brisbane today.
DURHAM, N.C. -- Finding and treating a tumor without disturbing normal tissue presents challenges -- sometimes the most effective therapies can be invasive and harsh.
Researchers at Duke University Medical Center have devised a way they might deliver the right therapy directly to tumors using special molecules, called aptamers, which specifically bind to living tumor tissue.
