Organic raw milk is consumed by an estimated 1-3 percent of the United States population and raw milk and cheeses are responsible for almost 70 percent of reported dairy outbreaks. On July 16, 2008, the Connecticut Department of Public Health identified two unrelated children who had experienced hemolytic uremic syndrome after consuming raw milk from the same farm. The authors investigated the situation further and found more cases of people affected by milk from the same farm.
LIVERMORE, Calif. - Arsenic - an element that triggers death for most Earthly life forms - is actually allowing for a bacterium to thrive and reproduce.
In a study that may prompt the rewriting of textbooks, a team of astrobiologists and chemists has found the first known living organism that can use arsenic in place of phosphorus in its major macromolecules. The new findings, published in the Dec. 2 Science Express, could redefine origins of life research and alter the way we describe life as we know it.
WASHINGTON – Moderate consumption of so-called energy drinks can improve people's response time on a lab test measuring behavioral control, but those benefits disappear as people drink more of the beverage, according to a study published by the American Psychological Association.
BEER-SHEVA, ISRAEL, December 2, 2010 -- Intense, individually tailored dietary treatment for acutely hospitalized elderly has a significant impact on mortality, according to a new study by researchers at Ben-Gurion University of the Negev.
New York (Dec. 2, 2010) – The Y chromosome is supposed to genetically seal a fetus’s fate in terms of gender. Males have one X and one Y chromosome, while females have two X chromosomes. Yet, in some families a child is born with an X and Y chromosome and develops physically as a female, although she may not menstruate, and her brothers and male cousins may have underdeveloped or ambiguous genitalia.
Using a new technology called "differential epistasis maps," an international team of scientists, led by researchers at the University of California, San Diego School of Medicine, has documented for the first time how a cellular genetic network completely rewires itself in response to stress by DNA-damaging agents.
CAMBRIDGE, Mass. -- A novel type of biomedical imaging, made possible by new advances in microscopy from scientists at Harvard University, is so fast and sensitive it can capture "video" of blood cells squeezing through capillaries.
AMHERST, Mass. – University of Massachusetts Amherst microbiologists Derek Lovley, Zarath Summers and colleagues report in the Dec. 2 issue of Science that they have discovered a new cooperative behavior in anaerobic bacteria, known as interspecies electron transfer, that could have important implications for the global carbon cycle and bioenergy.
TEMPE, Ariz. – Evidence that the toxic element arsenic can replace the essential nutrient phosphorus in biomolecules of a naturally occurring bacterium expands the scope of the search for life beyond Earth, according to Arizona State University scientists who are part of a NASA-funded research team reporting findings in the Dec. 2 online Science Express.
Austrian researchers have uncovered mutations throughout the mitochondrial genome that are associated with prostate cancer. An exciting aspect of the study, published by Cell Press on December 2 in the American Journal of Human Genetics, is the association of tRNA mutations with elevated levels of prostate-specific antigen (PSA) in Austrian men diagnosed with various stages of prostate cancer.
LA JOLLA, CA – November 30, 2010 – Scripps Research Institute scientists have made a significant leap forward in the drive to find a way to safely reprogram mature human cells and turn them into stem cells, which can then change into other cell types, such as nerve, heart, and liver cells. The ability to transform fully mature adult cells such as skin cells into stem cells has potentially profound implications for treating many diseases.
A protein that is crucial for regulating the self-renewal of normal prostate stem cells, needed to repair injured cells or restore normal cells killed by hormone withdrawal therapy for cancer, also aids the transformation of healthy cells into prostate cancer cells, researchers at UCLA have found.
The findings, by researchers with the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, may have important implications for controlling cancer growth and progression.
