CHAMPAIGN, Ill. — Like an unwelcome houseguest or itinerant squatter, the human body louse shows up when times are bad and always makes them worse. Now amulti-institutional team reports that it has sequenced the body louse genome, an achievement that will yield new insights into louse – and human – biology and evolution.
A new study indicates different delivery methods of newborn babies has a big effect on the types of microbial communities they harbor as they emerge into the world, findings with potential implications for the heath of infants as they grow and develop.
Women with the polycystic ovary syndrome (PCOS), the most common hormone imbalance in women of reproductive age, may be more vulnerable to exposure to the chemical bisphenol A (BPA), found in many plastic household items, according to a new study. The results will be presented Sunday at The Endocrine Society's 92nd Annual Meeting in San Diego.
Exposure to environmental levels of the industrial chemical bisphenol A, or BPA, in the womb and early life may cause long-lasting harm to testicular function, according to a new study conducted in animals. The results are being presented Monday at The Endocrine Society's 92nd Annual Meeting in San Diego.
A lawyer and researcher at the Johns Hopkins Berman Institute of Bioethics says a new legal and ethical framework needs to be placed around the donation and banking of human biological material, one that would more clearly define the terms of the material's use — and address donor expectations before research begins.
Certain brands have personalities that can actually change the way some people feel about themselves, according to a new study in the Journal of Consumer Research.
(Washington, DC) – A recent study of an ancient language provides new insights into the nature of linguistic evolution, with potential applications for today's world.

A preprint version is available on line at:http://lsadc.org/info/documents/2010/press-releases/kiparsky.pdf
Male fish are taking longer to be "feminized" by chemical contaminants that act as hormone disrupters in Colorado's Boulder Creek following the upgrade of a wastewater treatment plant in Boulder in 2008, according to a new study led by the University of Colorado at Boulder.
Women who experience early menopause appear to have more than twice the risk of having a heart attack, stroke or other cardiovascular disease event later in life than do women who do not go through early menopause, a new study indicates. The results will be presented Saturday at The Endocrine Society's 92nd Annual Meeting in San Diego.
Early menopause was defined as going through menopause before age 46, either naturally or surgically through removal of both ovaries.
Irvine, Calif., June 21, 2010 — UC Irvine researchers have developed the first "plastic antibodies" successfully employed in live organisms – stopping the spread of bee venom through the bloodstream of mice.
Tiny polymeric particles – just 1/50,000th the width of a human hair – were designed to match and encase melittin, a peptide in bee venom that causes cells to rupture, releasing their contents. Large quantities of melittin can lead to organ failure and death.
Male fish that used to be feminized after chemicals, such as the pharmaceutical ethinylestradiol, made it through the Boulder, Colo., Wastewater Treatment Plant and into Boulder Creek, are taking longer to become feminized after a plant upgrade to an activated sludge process, according to a new study. The results will be presented Sunday at The Endocrine Society's 92nd Annual Meeting in San Diego.
Adults with newly diagnosed diabetes are at higher long-term risk of serious liver disease, including cirrhosis and liver failure, according to a research article published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj092144.pdf.
The negative impact of diabetes on the eye, kidney and blood vessels is well-known, but little is known about its effect on the liver.
Under the principles of reasonable apprehension of bias, the appointment of Dr. Bernard Prigent to the Governing Council of the Canadian Institutes of Health Research (CIHR) may be considered untenable, states an analysis article published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100307.pdf.
