Standing up for athletes at risk

When a high school athlete drops dead, the rare but fatal condition called "sudden death syndrome" dominates the headlines. For reasons that remain a mystery to scientists, some young athletes — especially young males — begin to experience an unusual heart arrhythmia. With over-exertion, their hearts stop pumping, leading to sudden death.

Evolution can cause a rapid reduction in genome size

Happiest places have highest suicide rates says new research

The happiest countries and happiest U.S. states tend to have the highest suicide rates, according to research from the UK's University of Warwick, Hamilton College in New York and the Federal Reserve Bank of San Francisco.

New technique improves sensitivity of PCR pathogen detection

A new procedure devised by U.S. Department of Agriculture (USDA) scientists and colleagues can improve polymerase chain reaction (PCR)-based methods of detecting plant disease organisms.

Lawn of native grasses beats traditional lawn for lushness, weed resistance

A lawn of regionally native grasses would take less resources to maintain while providing as lush a carpet as a common turfgrass used in the South, according to a study by ecologists at The University of Texas at Austin's Lady Bird Johnson Wildflower Center.

"We created a lawn that needs less mowing and keeps weeds out better than a common American lawn option," said Dr. Mark Simmons, director of the center's Ecosystem Design Group, noting that this new approach could have a huge impact on pocketbooks and the environment.

Researchers construct RNA nanoparticles to safely deliver long-lasting therapy to cells

CINCINNATI—Nanotechnology researchers have known for years that RNA, the cousin of DNA, is a promising tool for nanotherapy, in which therapeutic agents can be delivered inside the body via nanoparticles. But the difficulties of producing long-lasting, therapeutic RNA that remains stable and non-toxic while entering targeted cells have posed challenges for their progress.

Worm studies shed light on human cancers

MADISON -- Research in the worm is shedding light on a protein associated with a number of different human cancers, and may point to a highly targeted way to treat them.

University of Wisconsin-Madison scientists were studying a worm protein called TFG-1, which is present in many cell types but whose exact role had never been understood. The scientists discovered that the protein controls key aspects of the movement, or secretion, of growth factors out of cells.

Starting a new metabolic path

Efforts to engineer new metabolic pathways into microbes for the inexpensive production of valuable chemical products, such as biofuels or therapeutic drugs, should get a significant boost in a new development from the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI). Researchers there have successfully demonstrated a technique they call "targeted proteomics" that speeds up and improves the ability to identify and quantify specific proteins within a cell or microorganism.

Entrepreneurship urged to stimulate the economy

Los Angeles, CA (APRIL XX, 2011) Economists have been pointing to the growth in entrepreneurship and small business hiring as two ways the US economy can speed the recovery process. In his first ever Facebook town hall meeting, President Obama expanded upon this search for economic solutions as part of the White House's "Startup America" initiative.

Discovery identifies elaborate G-protein network in plants

The most elaborate heterotrimeric G-protein network known to date in the plant kingdom has been identified by Dr. Sona Pandey, principal investigator at the Danforth Plant Science Center. The results of this research are published in the recent article, "An elaborate heterotirmeric G-protein family from soybean expands the diversity of G-protein networks," in the New Phytologist.

Prenatal exposure to certain pesticides may negatively impact cognitive development in children

Researchers at Mount Sinai School of Medicine have found that exposure during pregnancy to a family of pesticides called organophosphates may impair child cognitive development. The findings are published online in Environmental Health Perspectives.

Prenatal pesticide exposure tied to lower IQ in children

Berkeley – In a new study suggesting pesticides may be associated with the health and development of children, researchers at the University of California, Berkeley's School of Public Health have found that prenatal exposure to organophosphate pesticides – widely used on food crops – is related to lower intelligence scores at age 7.

Use of topical corticosteroids in children with eczema does not have negative side effects

A new study published in the journal Pediatric Dermatology reveals that routine, long-term use of topical corticosteroids (TCS) for treating children with eczema does not cause any significant, negative side effects.

Parental phobia of TCS is widespread and leads to poorly managed eczema in children. The commonest fear is that TCS use will "thin the skin." Parents fears are also shared by many health care providers, including pharmacists.

Prenatal exposure to common insecticide linked to decreases in cognitive functioning at age 7

Researchers from the Columbia Center for Children's Environmental Health at the Mailman School of Public Health report evidence of a link between prenatal exposure to the insecticide chlorpyrifos and deficits in IQ and working memory at age seven. This is the first study to evaluate the neurotoxicity of prenatal chlorpyrifos exposure on cognitive development at the time of school entry. Findings are online in Environmental Health Perspectives.

Antimalarial trees in East Africa threatened with extinction

NAIROBI (21 April 2011)— Research released in anticipation of World Malaria Day finds that plants in East Africa with promising antimalarial qualities—ones that have treated malaria symptoms in the region's communities for hundreds of years—are at risk of extinction. Scientists fear that these natural remedial qualities, and thus their potential to become a widespread treatment for malaria, could be lost forever.
