Nearly 75 percent of commercial pre-packaged meals and savory snacks for toddlers are high in sodium, according to research presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions.

The American Heart Association has released new recommendations for policy makers and public health providers to combat heart disease and stroke on a local level.
The "American Heart Association Guide for Improving Cardiovascular Health at the Community Level, 2013 Update" — evidence-based goals, strategies and recommendations for community-based public health interventions — is published in the American Heart Association journal Circulation.
GAINESVILLE, Fla. — A new University of Florida study of nearly 5,000 Haiti bird fossils shows contrary to a commonly held theory, human arrival 6,000 years ago didn't cause the island's birds to die simultaneously.
Scientists have confirmed that the pathogen that causes Lyme Disease—unlike any other known organism—can exist without iron, a metal that all other life needs to make proteins and enzymes. Instead of iron, the bacteria substitute manganese to make an essential enzyme, thus eluding immune system defenses that protect the body by starving pathogens of iron.
Though we all desire relief -- from stress, work, or pain -- little is known about the specific emotions underlying relief. New research from the Association for Psychological Science explores the psychological mechanisms associated with relief that occurs after the removal of pain, also known as pain offset relief.
NEW YORK (March 21, 2013) -- More than 50,000 stem cell transplants are performed each year worldwide. A research team led by Weill Cornell Medical College investigators may have solved a major issue of expanding adult hematopoietic stem cells (HSCs) outside the human body for clinical use in bone marrow transplantation -- a critical step towards producing a large supply of blood stem cells needed to restore a healthy blood system.
The over-the-counter anti-inflammatory drug naproxen may also exhibit antiviral activity against influenza A virus, according to a team of French scientists. The finding, the result of a structure-based investigation, is published online ahead of print in the journal Antimicrobial Agents and Chemotherapy.
Dartmouth researchers have taken an important step in the ongoing battle against secondhand tobacco smoke. They have pioneered the development of a breakthrough device that can immediately detect the presence of secondhand smoke and even third-hand smoke.
Smaller and lighter than a cellphone and about the size of a matchbox car, the device uses polymer films to collect and measure nicotine in the air. A sensor chip then records the data on an SD memory card. The technology is described in a new study appearing in the journal Nicotine and Tobacco Research.
Decades of research and three large-scale clinical trials have so far failed to yield an effective HIV vaccine, in large part because the virus evolves so rapidly that it can evade any vaccine-induced immune response.
Researchers from the University of Alberta are leading a charge among Canada's obesity experts and calling on the federal government to ban food and beverage ads that target children.
Kim Raine, a professor with the Centre for Health Promotion Studies in the School of Public Health at the U of A, says governments need to take action to stem the rising obesity epidemic. The only exception to a proposed food and beverage marketing ban would be for approved public health campaigns that promote healthy eating.
The discovery of the Rosetta Stone resolved a longstanding puzzle, permitting the translation of Egyptian hieroglyphs into Ancient Greek.
John Chaput, a researcher at Arizona State University's Biodesign Institute has been hunting for a biological Rosetta Stone—an enzyme allowing DNA's 4-letter language to be written into a simpler (and potentially more ancient) molecule that may have existed as a genetic pathway to DNA and RNA in the prebiotic world.
STANFORD, Calif. — Cells in the body need to be acutely aware of their surroundings. A signal from one direction may cause a cell to react in a very different way than if it had come from another direction. Unfortunately for researchers, such vital directional cues are lost when cells are removed from their natural environment to grow in an artificial broth of nutrients and growth factors.
This is an 11-by-11 gridiron structure (11 vertical helices by 11 horizontal helices) with 21 base pairs (bp) between junctions in both directions uses 5301 of 7249 nucleotidesof the M13 DNA scaffold strand and con-tains 120 staple strands (42 nucleotides each).

LA JOLLA, CA – March 21, 2012 – A team including scientists from The Scripps Research Institute (TSRI), the University of North Carolina at Chapel Hill and the Chinese Academy of Sciences has determined and analyzed the high-resolution atomic structures of two kinds of human serotonin receptor. The new findings help explain why some drugs that interact with these receptors have had unexpectedly complex and sometimes harmful effects.
A little more than a year after the FDA approved Kalydeco (Vx-770), the first drug of its kind to treat the underlying cause of cystic fibrosis, University of Missouri researchers believe they have found exactly how this drug works and how to improve its effectiveness in the future. Described in the current issue of the Proceedings of the National Academy of Sciences, MU researchers have redefined a key regulatory process in the defective protein responsible for cystic fibrosis that could change the way scientists approach the lethal genetic disease.
