Researchers have identified the function of one of the earliest antibodies in the animal kingdom, an ancient immunoglobulin that helps explain the evolution of human intestinal immune responses.
It plays a predominant role in the guts of fish and paves the way for a better understanding of hu... Read More
Plastic surgery patients have carried a new class of superbugs resistant to almost all antibiotics from South Asia to Britain and they could spread worldwide, researchers reported Wednesday.
Many hospital infections that were already difficult to treat have become even more impervious to drug... Read More
Bacteria that lives in hot springs in Japan may help solve one of the mysteries of the early evolution of complex organisms, according to a study publishing next week in PLoS Biology. It may also be the key to 21st century biofuel production.
Biochemists Alan Lambowitz and Georg Mohr began in... Read More
Staphylococcus aureus blood stream infections have a fatality risk of 30% to 40%; a narrow window of time is available to administer antibiotic therapy. The MicroPhage MRSA/MSSA Blood Culture Test from MicroPhage, Inc., Longmont, Colo., is the first in vitro diagnostic for direct identification ... Read More
Early diagnosis of diabetic retinopathy (DR) is vital to preserving the eye sight of a diabetes patient; however, less than half of the diabetes patients in the United States are screened due to cost or limited access to medical specialists. Oak Ridge National Laboratory, Oak Ridge, Tenn. and Th... Read More
