Dredging activity near reefs can more than double the frequency of diseases affecting corals by impacting the light and food they need to survive, a study showed Thursday. While scientists have known for decades that dredging can smother corals, researchers said this was the first time it has been linked to diseases. "Corals require both light and food to survive,"Read more

The release of the 2015 set of university league tables will alert secondary school pupils to the current academic standard of their higher education selections. Following summer term hard work, sixth form college and school leavers will quickly redirect their energy; the new focus will be preparation for life at university. Redirecting apprehension away from exam stress and refocusing onRead more

Higher levels of stress, hostility and depressive symptoms are associated with significantly increased risk of stroke or transient ischemic attack (TIA) in middle-age and older adults, according to new research in the American Heart Association journal Stroke. A TIA is a stroke caused by a temporary blockage of blood flow to the brain. Researchers investigated how psychological factors might influenceRead more

Cerebral palsy, a disability of the brain linked to problems in pregnancy or birth, may have an inherited cause, according to a study published on Wednesday. Norway researchers found that families where a close relative has cerebral palsy are at increased risk of giving birth to a child with this condition. The investigators trawled through a top-quality database covering theRead more

Iranian researchers from Amirkabir University of Technology produced polymeric nanocarriers that can be used in pharmaceutics and medical industries. The researchers proposed a new method for the production of medical nanocarriers that does not require complicated chemical reactions and enables the production of the product only in one step. In recent years, numerous researches have been carried out on theRead more

New research in Nature Genetics identifies a novel genetic and molecular pathway in the esophagus that causes eosinophillic esophagitis (EoE), opening up potential new therapeutic strategies for an enigmatic and hard-to-treat food allergy. EoE is a chronic inflammatory disorder of the esophagus. The condition is triggered by allergic hypersensitivity to certain foods and an over-accumulation in the esophagus of whiteRead more

People tend to choose friends that are genetically similar to themselves, so much so that a person's social circle could be made up of their fourth cousins, scientists said Monday. The research is based on the Framingham Heart Study in the northeastern US state of Massachusetts, which contains both extensive genetic detail -- 1.5 million markers -- and information aboutRead more

Iranian researchers from Materials and Energy Research Center succeeded in increasing primary pressure strength of artificial bone cement by using nanoparticles. In the production of the cement, those types of nanoparticles were used that do not harm the biocompatibility of implants and will not be rejected by body's immunity system. Despite unique advantages of phosphate calcium cements, their low mechanicalRead more

Iranian researchers in association with their Malaysian colleagues produced non-enzyme sensor that is able to measure poisonous and harmful species in industrial and medical applications. Efforts have been made in the production of the sensor to obtain reliable and valid data by using a simple and cost-effective method. Hydrogen peroxide is one of the important oxidants that have numerous applicationsRead more
