Eating up to 100 g of chocolate every day is linked to lowered heart disease and stroke risk. The calculations showed that compared with those who ate no chocolate higher intake was linked to an 11% lower risk of cardiovascular disease and a 25% lower risk of associated death. There doesn't seem to be any evidence for cutting out chocolateRead more

"This new chemogenetic tool will show us how brain circuits can be more effectively targeted to treat human disease, " said Bryan L. Roth, MD, PhD, the Michael Hooker Distinguished Professor of Protein Therapeutics and Translational Proteomics at the UNC School of Medicine. "The problem facing medical science is that although most approved drugs target these brain receptors, it remainsRead more

Children with good verbal working memories are better at covering up lies, researchers found in a study of 6- and 7-year-olds. There was no difference found in visuo-spatial memory between good and bad liars, the study found, because lying generally does not involve recalling images, so visual information is less important to carrying a fake narrative. "This research shows thatRead more

The whooping cough vaccine may be allowing people to transmit the disease without showing any symptoms, which researchers say could be contributing to its comeback in the last few years. Children have been receiving the current version of the vaccine since the 1990s, which uses a handful of pertussis bacteria proteins, rather than inactivated cells of the bacteria, in orderRead more

A genetic approach has been used by researchers to show link between height and disease. The shorter you are- the more your risk of coronary heart disease. That's the key finding of a new study led by the University of Leicester which discovered that every 2.5 inches change in your height affected your risk of coronary heart disease by 13.5%.Read more

Iranian researchers produced and studied a biosensor with the capability of measuring biological indices of heart diseases and disorders. The potential of these diseases and heart attack can be predicted by using the sensor. Results of the research have applications in medical and clinical studies, and in pathology laboratories. A biosensor has been designed in this research that enables theRead more

Iranian researchers produced a polymeric nanocomposite which can be used in targeted drug delivery systems. The nanocomposite enables the controlled release of drug in the target tissue and reduces the side effects of the drug as well as increasing its effectiveness. Targeted drug delivery systems are used to overcome problems, including fluctuation of drug dosage in blood, reduction in theRead more

Iranian researchers used nanotechnology and produced a type of nanocatalyst which modifies the performance of fuel cells. Natural materials with large and rich sources in the country have been used in the production of the catalyst. Therefore, the production of the catalyst is cost-effective. The application of fuel cells provides the opportunity to produce energy without creating any environmental pollution.Read more

Iranian researchers from Khajeh Nasir Toosi University of Technology in a theoretical study investigated the dynamic interaction between two perpendicular carbon nanotubes. Results of the research have applications in the designing of nanosensors, medical nano-tools and electromechanical devices. Carbon nanotubes have attracted the attention of many researchers in recent decades due to their desirable physical, chemical and mechanical properties. AlthoughRead more

Not everyone is able to tune into their heartbeat, according to an international team of researchers -- and half of us under- or over-estimate our ability.   In research published in the journal Cerebral Cortex, a team of scientists led by the University of Cambridge and the Medical Research Council (MRC) Cognition and Brain Sciences Unit, Cambridge, studied not onlyRead more
