Scripps Florida scientists identify gene that plays a surprising role in combating aging

JUPITER, FL, July 17, 2014 – It is something of an eternal question: Can we slow or even reverse the aging process? Even though genetic manipulations can, in fact, alter some cellular dynamics, little is known about the mechanisms of the aging process in living organisms.

Danish DNA could be key to happiness

Genetics could be the key to explaining nation's levels of happiness, according to research from the University of Warwick.

Economists at the University's Centre for Competitive Advantage in the Global Economy (CAGE) have looked at why certain countries top the world happiness rankings. In particular they have found the closer a nation is to the genetic makeup of Denmark, the happier that country is. The research could help to solve the puzzle of why a country like Denmark so regularly tops the world happiness rankings.

Anti-tank missile detector joins the fight against malaria

State-of-the-art military hardware could soon fight malaria, one of the most deadly diseases on the planet.

Researchers at Monash University and the University of Melbourne have used an anti-tank Javelin missile detector, more commonly used in warfare to detect the enemy, in a new test to rapidly identify malaria parasites in blood.

Scientists say the novel idea, published in the journal Analysis, could set a new gold standard for malaria testing.

Eradicating fatal sleeping sickness by killing off the tsetse fly

A Brigham Young University ecologist is playing a role in the effort to curb a deadly disease affecting developing nations across equatorial Africa.

Steven L. Peck, a BYU professor of biology, has lent his expertise in understanding insect movement to help shape a UN-sanctioned eradication effort of the tsetse fly—a creature that passes the fatal African sleeping sickness to humans, domestic animals, and wildlife.

Investing in sexual and reproductive health of 10 to 14 year olds yields lifetime benefits

WASHINGTON -- Age 10 to 14 years, a time when both girls and boys are constructing their own identities and are typically open to new ideas and influences, provides a unique narrow window of opportunity for parents, teachers, healthcare providers and others to facilitate transition into healthy teenage and adulthood years according to researchers from Georgetown University's Institute for Reproductive Health who note the lack worldwide of programs to help children of this age navigate passage from childhood to adulthood.

Women's professional self-identity impacts on childcare balance, but not men's

A new study finds that the more a woman self-identifies with her profession, the more paid hours she works and the less time she spends with the couple's children, but the more equal the childcare balance is between a couple.

However, the more a woman identifies herself with motherhood, the less time the father spends with the children.

And while the more a man self-identifies as a parent the more time he spends with children, this had no impact on the amount of time the woman spends on childcare – regardless of her self-identity.

Duck migration study reveals importance of conserving wetlands, MU researchers find

COLUMBIA, Mo. – During the 2011 and 2012 migration seasons, University of Missouri researchers monitored mallard ducks with new remote satellite tracking technology, marking the first time ducks have been tracked closely during the entirety of their migration from Canada to the American Midwest and back. The research revealed that mallards use public and private wetland conservation areas extensively as they travel hundreds of miles across the continent.

National Xenopus resource at the MBL innovates new way to study proteins

WOODS HOLE, Mass.— Proteomics, the study of large groups of proteins, can enhance our understanding of a wide range of organisms, with applications in medicine and developmental biology. Such analyses traditionally require a complete genome for the organism being studied in order to obtain a reference set of proteins. However, many organisms that hold potential for proteomic analysis do not yet have completely sequenced and well-interpreted genomes because the costs, in terms of both time and money, can be prohibitive. Xenopus laevis, the African clawed frog, is one such species.

Study shows how effects of starvation can be passed to future generations

NEW YORK, NY — Evidence from human famines and animal studies suggests that starvation can affect the health of descendants of famished individuals. But how such an acquired trait might be transmitted from one generation to the next has not been clear. A new study, involving roundworms, shows that starvation induces specific changes in so-called small RNAs and that these changes are inherited through at least three consecutive generations, apparently without any DNA involvement.

How does working part-time versus working full-time affect breastfeeding goals?

Los Angeles, CA -- Breastfeeding is known to provide significant health benefits for both infants and their mothers. However, while many women intend to breastfeed despite returning to work, a new study finds that mothers who plan to breastfeed for at least three months but return to work full-time are less likely to meet their breastfeeding goals. Conversely, there is no association between women who return to work part-time and failure to reach the breastfeeding goal of at least three months. This new study was published today in the Journal of Human Lactation.

Best anticoagulants after orthopedic procedures depends on type of surgery

Current guidelines do not distinguish between aspirin and more potent blood thinners for protecting against blood clots in patients who undergo major orthopedic operations, leaving the decision up to individual clinicians. A new analysis published today in the Journal of Hospital Medicine provides much-needed information that summarizes existing studies about which medications are best after different types of surgery.

Niacin too dangerous for routine cholesterol therapy

CHICAGO --- After 50 years of being a mainstay cholesterol therapy, niacin should no longer be prescribed for most patients due to potential increased risk of death, dangerous side effects and no benefit in reducing heart attacks and strokes, writes Northwestern Medicine® preventive cardiologist Donald Lloyd-Jones, M.D., in a New England Journal of Medicine editorial.

NIH scientists identify gene linked to fatal inflammatory disease in children

Investigators have identified a gene that underlies a very rare but devastating autoinflammatory condition in children. Several existing drugs have shown therapeutic potential in laboratory studies, and one is currently being studied in children with the disease, which the researchers named STING-associated vasculopathy with onset in infancy (SAVI). The findings appeared online today in the New England Journal of Medicine. The research was done at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health.

Cell membrane proteins give up their secrets

HOUSTON – (July 16, 2014) – Rice University scientists have succeeded in analyzing transmembrane protein folding in the same way they study the proteins' free-floating, globular cousins.

Rice theoretical biologist Peter Wolynes and his team at the university's Center for Theoretical Biological Physics (CTBP) have applied his energy landscape theory to proteins that are hard to view because they live and work primarily inside cell membranes.

Marginal life expectancy benefit from contralateral prophylactic mastectomy

The choice of contralateral prophylactic mastectomy (CPM) by women with breast cancer (BC) diagnosed in one breast has recently increased in the US but may confer only a marginal life expectancy benefit depending on the type and stage of cancer, according to a study published July 16 in the JNCI: Journal of the National Cancer Institute.
