A new therapy for metastatic prostate cancer has shown considerable promise in early clinical trials involving patients whose disease has become resistant to current drugs.
CHICAGO - The American Dietetic Association has released an updated position on functional foods that says fortified, enriched or enhanced foods can benefit a person's health when consumed as part of a varied diet, encourages further research and urges continued efforts to educate the public on such foods.
AUSTIN, Texas - Hospice and palliative medicine investigators presented preliminary research findings at paper sessions held during the Annual Assembly of the American Academy of Hospice and Palliative Medicine, in collaboration with the Hospice and Palliative Nurses Association, on March 25- 28, 2009, at the Austin Convention Center in Austin, Texas.
San Diego, CA (March 20, 2009) -A rigorous environmental cleaning intervention can reduce the transmission of methicillin-resistant Staphylococcus aureus (MRSA) and other multidrug-resistant organisms in hospital intensive care units (ICUs), according to a new study released today at the annual meeting of the Society for Healthcare Epidemiology of America (SHEA).
Escherichia coli is a commonly used indicator organism for detecting the presence of fecal contamination in drinking water supplies. The importance of E. coli as an indicator organism has led to several studies looking at the transport behavior of this important microorganism in groundwater environments. Commonly only a single strain of E.
Researchers say a newly tested method for producing super dense, defect-free, thin polymer films is the fastest, most efficient method ever achieved and it may dramatically improve microelectronic storage capabilities such as those in computer memory sticks.
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a devastating condition in which motor neuron degeneration causes progressive loss of movement and muscle tone, leading to death.
An international team of scientists led by a Princeton University group recently discovered that on the surface of certain materials collective arrangements of electrons move in ways that mimic the presence of a magnetic field where none is present.
Using compounds preserved in sedimentary rocks more than 635 million years old, researchers have found some of the earliest evidence for the existence of animals.
The principle behind whispering galleries -- where words spoken softly beneath a domed ceiling or in a vault can be clearly heard on the opposite side of the chamber -- has been used to achieve what could prove to be a significant breakthrough in the miniaturization of lasers.
Another important piece to the photosynthesis puzzle is now in place. Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have identified one of the key molecules that help protect plants from oxidation damage as the result of absorbing too much light. The researchers determined that when chlorophyll molecules in green plants take in more solar energy than they are able to immediately use, molecules of zeaxanthin, a member of the carotenoid family of pigment molecules, carry away the excess energy.
First they were seen to go away, now, for the first time, they've been seen coming back. An international team of researchers at KamLAND, an underground neutrino detector in central Japan, has shown that not only do anti-neutrinos emanating from nearby nuclear reactors ''disappear,'' they also ''reappear.'' This is further evidence that the three known types or ''flavors'' of neutrinos -- electron, muon and tau -- all have mass and can oscillate or change from one type to another.
As summer draws to a close in the southern hemisphere of Uranus, storm clouds are brewing in the upper atmosphere, northern hemisphere winds are gusting to 250 miles per hour, and the planet's rings are getting brighter every day. This weather report comes from researchers using the Keck II 10-meter telescope atop Mauna Kea volcano in Hawaii, where recent observations are proving that Uranus is not the ''boring and unchanging'' planet people have assumed.
Just as the Microtechnology Age was built upon the introduction of impurities into crystals of semiconductor materials, so, too, will crystalline doping be the bedrock upon which the Nanotechnology Age is built. To advance the arrival of this next technological era at a faster pace, however, scientists need a better understanding of what happens to nano-sized crystals under the various forms of doping.
Scientists working at Los Alamos National Laboratory have begun to analyze data from an instrument aboard the joint U.S.-European spacecraft Cassini. Although Cassini has only been orbiting the planet Saturn since July 1, data from the Cassini Plasma Spectrometer has already begun to provide new information about the curious nature of Saturn's space environment. CAPS had been detecting advance readings for several days before Cassini finally crossed the bow shock that exists in the solar wind ahead of the magnetosphere, a huge magnetic field bubble produced in the solar wind by Saturn's strong magnetic field.
