Nearly 1 in 5 young adults has high blood pressure, study shows

The number of young adults in the United States with high blood pressure may be much higher than previously reported, according to a new study by researchers at the University of North Carolina at Chapel Hill.

Endangered gourmet sea snail could be doomed by increasing ocean acidity

Increasing levels of ocean acidity could spell doom for British Columbia's already beleaguered northern abalone, according to the first study to provide direct experimental evidence that changing sea water chemistry is negatively affecting an endangered species.

New Canadian blood pressure education program a powerful tool in fight to reduce stroke

(Toronto, May 25, 2011): High blood pressure – the silent killer – is taking a hit from a new, ground-breaking treatment program from the Heart and Stroke Foundation of Ontario.

Last Sunday, in New York City, Dr. Sheldon Tobe, Chair of the Canadian Hypertension Education Program (CHEP) and a long-standing Heart and Stroke Foundation researcher, unveiled a new and powerful tool in the management of hypertension at the American Society of Hypertension (ASH) Scientific Meeting —The Heart&Stroke Hypertension Management Program.

New study provides global analysis of seagrass extinction risk

A team of 21 researchers from 11 nations, including professor Robert "JJ" Orth of the Virginia Institute of Marine Science, has completed the first-ever study of the risk of extinction for individual seagrass species around the world.

The 4-year study, requested by the International Union for the Conservation of Nature (IUCN), shows that 10 of the 72 known seagrass species (14%) are at an elevated risk of extinction, while 3 species qualify as endangered.

Mating rivalry among furred and feathered: Variety is spice of life

Montreal, May 25, 2011 – Birds do it. Bees do it. Fish, lobsters, frogs and lizards do it, too. But when it comes to securing a mate in the animal world, variety is literally the spice of life.

A group of scientists from Simon Fraser University, Concordia University and Dalhousie University has found flexibility in mating rituals is the key to reproductive success when males outnumber females.

The research team pored through hundreds of investigations on mating trends in mammals, insects, fish, crustaceans, amphibians and reptiles.

Fish species discovered by LSU researcher makes 2011 top 10 list

BATON ROUGE – The International Institute for Species Exploration at Arizona State University and a committee of taxonomists from around the world announced their picks for the top 10 new species described in 2010. Among their top picks is Halieutichthys intermedius, a pancake batfish recently discovered by Prosanta Chakrabarty, curator of fishes at LSU's Museum of Natural Science, and colleagues.

Public universities place greater focus on internal research services than public ones do

Research expenditure has increased in Spain, as has the focus on research performance. However, the internal services that universities provide to support research, both in terms of infrastructure and staff, have not improved, according to a study published in the journal The Service Industries Journal, which also shows that public universities outperform private ones in this respect.

Vitamin D increases speed of sperm cells

Vitamin D is important for optimal reproductive function in both animals and humans. It has long been known that serum vitamin D level is important for reproductive function in various animals, but now researchers from the University of Copenhagen and Copenhagen University Hospital have shown that this relationship can also be demonstrated in humans.

Enzyme prevents fatal heart condition associated with athletes

Scientists have discovered an important enzyme molecule that may prevent fatal cardiac disorders associated with cardiac hypertrophy – the leading cause of sudden cardiac death in young athletes.

Cardiac hypertrophy is a disease of the heart muscle where a portion of the tissue is thickened without any obvious cause. It is commonly linked to high blood pressure (hypertension) and excessive exercises and results in a shrinking of the heart chamber and a reduction of its blood-pumping volume.

P&G pioneering the 'Omics' revolution to solve molecular puzzles in beauty and grooming

Seoul, Korea, 24th May 2011 – Procter & Gamble (NYSE: PG) today unveiled its pioneering efforts in the breakthrough field of 'Omics' that is set to solve the molecular puzzles of beauty and leapfrog innovations in this space. Twenty-one years after the start of the Human Genome Project in 1990, the science of genomics has come of age and led to a new era of 'Omics'-based research. This approach brings together genomics, proteomics and metabolomics to map the entire biological system, illuminating new pathways to better skin and hair science for years to come.

'Sweet wheat' for tastier and more healthful baking

"Sweet wheat" has the potential for joining that summertime delight among vegetables — sweet corn — as a tasty and healthful part of the diet, the scientific team that developed this mutant form of wheat concludes in a new study. The report appears in the ACS' Journal of Agricultural and Food Chemistry.

Recycling of Alzheimer's proteins could be key to new treatments

The formation of abnormal strands of protein called amyloid fibrils — associated with two dozen diseases ranging from Alzheimer's to type-2 diabetes — may not be permanent and irreversible as previously thought, scientists are reporting in the Journal of the American Chemical Society. Rather, protein molecules are constantly attaching and detaching from the fibrils, in a recycling process that could be manipulated to yield new treatments for Alzheimer's and other diseases.

8 hours of resistance

Temptations to exceed the speed limit are always plentiful, but only reckless drivers give in to such impulses. Likewise, numerous growth factors always abound in our bodies, but only cancerous cells are quickly "tempted" by these chemicals to divide again and again. Healthy cells, in contrast, divide only after being exposed to growth factors for eight continuous hours. What happens during these eight hours in a healthy cell that resists the call to divide? And even more important, what fails to work properly in the cancerous cell during these same hours?

Immune system release valve

The molecular machines that defend our body against infection don't huff and puff, but some of them The molecular machines that defend our body against infection don't huff and puff, but some of them apparently operate on the same principle as a steam engine.

Women who start prenatal vitamins early are less likely to have children with autism

Women who reported not taking a daily prenatal vitamin immediately before and during the first month of pregnancy were nearly twice as likely to have a child with an autism spectrum disorder as women who did take the supplements — and the associated risk rose to seven times as great when combined with a high-risk genetic make-up, a study by researchers at the UC Davis MIND Institute has found.
