Source of protection against saturated fat found

A new report in the December Cell Metabolism identifies a protein without which diets high in saturated fat lead to a massive inflammatory response that can prove fatal. The studies in mice suggest that deficiencies in this protective pathway could promote inflammation in those who regularly consume high levels of saturated fat.

"In mice without this protein that ate a lot of saturated fat, the lymph nodes blew up to extreme levels," said Sander Kersten of the Nutrigenomics Consortium and Wageningen University in the Netherlands. "I'd never seen anything like it before."

Study finds anti-microbials a common cause of drug-induced liver injury and failure

New research shows that anti-microbial medications are a common cause of drug-induced liver injury (DILI) leading to acute liver failure (ALF), with women and minorities disproportionately affected. While ALF evolves slowly, once it does occur a spontaneous recovery is unlikely; however liver transplantation offers an excellent survival rate. Full findings of this ten-year prospective study are published in the December issue of Hepatology, a journal of the American Association for the Study of Liver Diseases.

Water resources played important role in patterns of human settlement, new UNH research shows

DURHAM, N.H. – Once lost in the mists of time, the colonial hydrology of the northeastern United States has been reconstructed by a team of geoscientists, biological scientists and social scientists, including University of New Hampshire Ph.D. candidate Christopher Pastore.

Mayo researchers find drug-resistant HIV patients with unimpaired immune cells

ROCHESTER, Minn. -- Mayo Clinic researchers have shown why, in a minority of HIV patients, immune function improves despite a lack of response to standard anti-retroviral treatment. In these cases, researchers say, the virus has lost its ability to kill immune cells. The findings appear in the online journal PLoS Pathogens.

Alternative therapies may leave asthmatics gasping

Montreal, November 30, 2010 – Approximately 13 percent of parents turn to alternative therapies to treat their children's asthma, according to a new study from the Université de Montréal. The findings, published recently in the Canadian Respiratory Journal, suggest that this trend is associated with a two-fold higher rate of poor asthma control in children.

Study: Ecological effects of biodiversity loss underestimated

Children aren't the only youngsters who are picky eaters: More than half of all species are believed to change their diets -- sometimes more than once -- between birth and adulthood. And a new study by ecologists at Rice University and the University of California, Santa Barbara, finds this pattern has major implications for the survival of threatened species and the stability of natural ecosystems.

Public health in the genomic era: A global issue

INDIANAPOLIS -- The major challenge for public health in the era of genomics is to generate the base of evidence necessary to demonstrate when use of genomic information in public health can improve health outcomes in a safe, effective and cost-effective manner, participants at an international meeting have concluded.

Pioneering study reveals UK biodiversity hotspot

Scientists are calling for radical new approaches to conservation following the first biodiversity audit of its kind.

Led by the University of East Anglia (UEA), with partners Natural England, the Forestry Commission, Norfolk and Suffolk Biodiversity Partnerships and County Councils, the Brecks Partnership, and Plantlife, the painstaking study pooled information on every plant and animal species recorded in Breckland – a special landscape of heathland, forest and farmland stretching across the Norfolk and Suffolk border.

Snakes on a rope: Researchers take a unique look at the climbing abilities of boa constrictors

In a unique study involving young boa constrictors, University of Cincinnati researchers put snakes to work on varying diameters and flexibility of vertical rope to examine how they might move around on branches and vines to gather food and escape enemies in their natural habitat. The findings by Greg Byrnes, a University of Cincinnati postdoctoral fellow in the department of biological sciences, and Bruce C. Jayne, a UC professor of biology, are published in the December issue of The Journal of Experimental Biology.

World's fastest camera takes a new look at biosensing

A European consortium comprising the National Physical Laboratory, ST Microelectronics, the University of Edinburgh, and TU Delft has been involved in the development and application of the Megaframe Imager - an ultrafast camera capable of recording images at the incredible rate of one million frames

Since the introduction of solid-state optical sensors, like those found in digital cameras, the main trend has been towards increasing the resolution (i.e. number of pixels) while miniaturising the chip.

Mystery dissolves with calcium pump discovery

Mystery dissolves with calcium pump discovery

Geo-microbiologists from Arizona State University have solved a long-standing conundrum about how some photosynthetic microorganisms, endolithic cyanobacteria, bore their way into limestone, sand grains, mussel shells, coral skeletons and other substrates composed of carbonate.

Women with migraine with aura have better outcomes after stroke

DALLAS, Nov. 29, 2010 — Women with a history of migraine headache with aura (transient neurological symptoms, mostly visual impairments) are at increased risk of stroke. However, according to new research reported in Circulation: Journal of the American Heart Association stroke events in women with migraine with aura are more likely to have mild or no disability compared to those without migraine.

Heat wave deaths highest in early summer

New Haven, Conn.—The risk of dying from a heat wave is highest when heat waves occur early in the summer and are hotter and longer than usual, according to a Yale study published in the journal Environmental Health Perspectives (EHP).

Drop in breast cancer rates directly tied to reduced hormone therapy

In a new UCSF study of more than 2 million mammogram screenings performed on nearly 700,000 women in the United States, scientists for the first time show a direct link between reduced hormone therapy and declines in ductal carcinoma in situ (DCIS) as well as invasive breast cancer. The researchers saw such a striking decrease, they believe they also have uncovered indirect evidence that hormones promote breast tumor growth.

The declines occurred in the age groups that most widely embraced then abandoned hormone therapy.
