NIH media availability: Protein linked to increased risk of heart failure and death in older adults

WHAT: A protein known as galectin-3 can identify people at higher risk of heart failure, according to new research supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. This research is based on work from the NHLBI's Framingham Heart Study, which began in 1948 and has been the leading source of research findings about heart disease risk factors.

Tracing the Paralympic movement's 'freak show' roots

(Edmonton) Danielle Peers has lived the thrill and pressure, revelled in competition and brought home hardware from the Paralympic Games. But beneath the cheers, the University of Alberta researcher questions whether the Paralympic movement is as empowering as its benevolent image.

The former Paralympian bronze medallist and women's wheelchair basketball world champion says the history of the Paralympic movement dates to the freak shows of the 19th century—and even today's modern games are a spectacle of curiosity that reinforces disability.

Collagen-seeking synthetic protein could lead doctors to tumor locations

Johns Hopkins researchers have created a synthetic protein that, when activated by ultraviolet light, can guide doctors to places within the body where cancer, arthritis and other serious medical disorders can be detected.

Controlling gait of horses may be possible, says key study from Texas A&M

COLLEGE STATION Aug. 29, 2012 – Analysis of a specific mutation in a gene in horses that affects the ability of horses to use alternate gaits is strongly related to racing performance and is advantageous for harness-racing horses. In domestic horses, the mutation has had a major impact on their diversification, as the altered gait characteristics of a number of breeds apparently require this mutation, according to a study that includes a Texas A&M University researcher.

Computer viruses could take a lesson from showy peacocks

EAST LANSING, Mich. — Computer viruses are constantly replicating throughout computer networks and wreaking havoc. But what if they had to find mates in order to reproduce?

In the current issue of Evolution, Michigan State University researchers created the digital equivalent of spring break to see how mate attraction played out through computer programs, said Chris Chandler, MSU postdoctoral researcher at MSU's BEACON Center for the Study of Evolution in Action.

Eyeless Australian fish have closest relatives in Madagascar

A team of researchers from Louisiana State University and the American Museum of Natural History has discovered that two groups of blind cave fishes on opposite sides of the Indian Ocean are each other's closest relatives. Through comprehensive DNA analysis, the researchers determined that these eyeless fishes, one group from Madagascar and the other from similar subterranean habitats in Australia, descended from a common ancestor before being separated by continental drift nearly 100 million years ago.

Nurse leader resistance perceived as a barrier to high-quality, evidence-based patient care

COLUMBUS, Ohio - A new national survey of more than 1,000 registered nurses suggests that serious barriers - including resistance from nursing leaders - prevent nurses from implementing evidence-based practices that improve patient outcomes.

When survey respondents ranked these barriers, the top five included resistance from nursing leaders and nurse managers - a finding that hasn't been reported in previous similar studies - as well as politics and organizational cultures that avoid change.

Mayo Clinic: Diabetes can be controlled in patients after pancreas removal

JACKSONVILLE, Fla. — Removing the entire pancreas in patients with cancer or precancerous cysts in part of the organ does not result in unmanageable diabetes — as many physicians previously believed, research at Mayo Clinic in Florida has found.

Study pinpoints malignant mesothelioma patients likely to benefit from drug pemetrexed

Previous studies have hypothesized that low levels of the enzyme thymidylate synthase (TS) likely mark patients who will benefit from the drug pemetrexed – but results have been inconclusive at best and at times contradictory. A University of Colorado Cancer Center study recently published in the Journal of Thoracic Oncology provides an explanation why: only in combination with high levels of a second enzyme, FPGS, does low TS predict response to pemetrexed in patients with malignant pleural mesothelioma.

Study suggests large methane reservoirs beneath Antarctic ice sheet

SANTA CRUZ, CA -- The Antarctic Ice Sheet could be an overlooked but important source of methane, a potent greenhouse gas, according to a report in the August 30 issue of Nature by an international team of scientists.

The new study demonstrates that old organic matter in sedimentary basins located beneath the Antarctic Ice Sheet may have been converted to methane by micro-organisms living under oxygen-deprived conditions. The methane could be released to the atmosphere if the ice sheet shrinks and exposes these old sedimentary basins.

Potential methane reservoirs beneath Antarctica

The new study demonstrates that old organic matter in sedimentary basins located beneath the Antarctic Ice Sheet may have been converted to methane by micro-organisms living under oxygen-deprived conditions. The methane could be released to the atmosphere if the ice sheet shrinks and exposes these old sedimentary basins.

The researchers estimate that 50 per cent of the West Antarctic Ice Sheet (1 million km2) and 25 per cent of the East Antarctic Ice Sheet (2.5 million km2) overlies preglacial sedimentary basins, containing about 21,000 billion tonnes of organic carbon.

NIH scientists map first steps in flu antibody development

National Institutes of Health scientists have identified how a kind of immature immune cell responds to a part of influenza virus and have traced the path those cells take to generate antibodies that can neutralize a wide range of influenza virus strains. Study researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of NIH, were led by Gary Nabel, M.D., Ph.D., director of NIAID's Vaccine Research Center. Their findings appear online in advance of print in Nature.

Many trendy 'microgreens' are more nutritious than their mature counterparts

The first scientific analysis of nutrient levels in edible microgreens has found that many of those trendy seedlings of green vegetables and herbs have more vitamins and healthful nutrients than their fully grown counterparts. A report on the research appears in ACS' Journal of Agricultural and Food Chemistry.

Warning on deterioration of famous Swedish warship, Vasa

The famous warship, Vasa, displayed in a museum that gets 1.2 million visitors every year and ranks as one of Sweden's most popular tourist attractions, is deteriorating despite ongoing preservation efforts, scientists are reporting. Their study, citing a "significant" loss of strength in the ship's wood, appears in ACS' journal Biomacromolecules.

New antibacterial coating for sutures could reduce infections after surgery

Responding to an urgent need for better antibacterial coatings on surgical sutures, scientists are reporting the discovery of a new coating that is almost 1,000 times more effective than the most widely used commercial coating. Their report appears in ACS' journal Langmuir.
