Calorie-Restricted Diet Keeps Heart Young
19.6.2012 | Press monitoring
People who restrict their caloric intake in an effort to live longer have hearts that function more like those in people who are 20 years younger. Researchers at Washington University School of Medicine in St. Louis have found that a key measure of the heart's ability to adapt to physical activity, stress, sleep and other factors that influence...
Internal cellular sensors make Salmonella dangerous
18.6.2012 | Press monitoring
Salmonella becomes dangerously virulent only when molecular sensors within the organism sense changes in the environment, a team of researchers from the Yale School of Medicine and the Yale Microbial Diversity Institute report in the June 14 issue of the journal Nature. The Nature paper discovers that it is not the direct threat from the...
Unhealthy Lifestyles Have Little Impact On Sperm Quality
15.6.2012 | Press monitoring
Lifestyle advice given by doctors to men diagnosed with infertility should be radically overhauled according to research published June 13. However, a team of scientists from the Universities of Manchester and Sheffield have found that many common lifestyle choices make little difference to male fertility, based on how many swimming sperm men...
Sick from Your Stomach: Bacterial Changes May Trigger Diseases Like Rheumatoid Arthritis
14.6.2012 | Press monitoring
The billions of bugs in our guts have a newfound role: regulating the immune system and related autoimmune diseases such as rheumatoid arthritis, according to researchers at Mayo Clinic and the University of Illinois at Urbana-Champaign. Larger-than-normal populations of specific gut bacteria may trigger the development of diseases like...
Parasitic Plants Steal Genes from Their Hosts
13.6.2012 | Press monitoring
New research published June 8 in BioMed Central's open access journal BMC Genomics reveals that the Malaysian parasitic plant Rafflesia cantleyi, with its 50cm diameter flowers, has 'stolen' genes from its host Tetrastigma rafflesiae. Analysis of these genes shows that their functions range from respiration to metabolism, and that some of them...

Celiac disease affects millions of people worldwide, but many sufferers are not aware they have the condition or may have been misdiagnosed with other illnesses. A pioneering new test developed with EU-funding should soon be available in hospitals, offering an accurate, quick, cost-effective diagnosis and monitoring solution. Current testing...
Milk Ingredient Does a Waistline Good
8.6.2012 | Press monitoring
A natural ingredient found in milk can protect against obesity even as mice continue to enjoy diets that are high in fat. The researchers who report their findings in the June Cell Metabolism, a Cell Press publication, liken this milk ingredient to a new kind of vitamin. Mice that take nicotinamide riboside in fairly high doses along with their...
Investigational Diabetes Drug May Have Fewer Side Effects
7.6.2012 | Press monitoring
Drugs for type 2 diabetes can contribute to weight gain, bone fractures and cardiovascular problems, but in mice, an investigational drug appears to improve insulin sensitivity without those troublesome side effects, researchers at Washington University School of Medicine in St. Louis have shown. The experimental medicine works through a...
Light-Induced Delivery of Nitric Oxide Eradicates Drug-Resistant Bacteria
6.6.2012 | Press monitoring
Researchers at UC Santa Cruz have developed a novel approach for eradicating drug-resistant bacteria from wounds and skin infections, using light to trigger the controlled release of nitric oxide. The UCSC team developed a photoactive compound that releases nitric oxide when exposed to light, and loaded it into a porous, biocompatible material...
