Arabic movie subtitles, Korean tweets, Russian novels, Chinese websites, English lyrics, and even the war-torn pages of the New York Times - research examining billions of words, showed that these sources -- and all human language -- skew toward the use of happy words. This Big Data study confirms the 1969 Pollyanna Hypothesis that there is a universal human tendencyRead more

A major study shows new evidence that long-term smoking could cause thinning of the brain's cortex. Years ago, children were warned that smoking could stunt their growth, but now a major study by an international team including the Montreal Neurological Institute at McGill University and the University of Edinburgh shows new evidence that long-term smoking could cause thinning of theRead more

Middle-school children who consume heavily sweetened energy drinks are 66 percent more likely to be at risk for hyperactivity and inattention symptoms, a new study found. The finding has implications for school success and lends support to existing recommendations to limit the amount of sweetened beverages schoolchildren drink. The authors also recommend that children avoid energy drinks, which in additionRead more

An expert in biophysics, epigenetics and food science is working to gain a deeper understanding of genome compaction within the cells in our bodies and the way it influences gene expression. "Molecular gastronomy," is dedicated to the study of the physical and chemical processes involved in cooking and eating. During the Biophysical Society's 59th Annual Meeting in Baltimore, Md., Feb.Read more

Iranian researchers from Uremia University succeeded in the production of a new type of nanocoating to increase the corrosion resistance of copper. The nanocoating can be produced through a simple and cheap method by using eco-friendly materials. Copper is widely used in various industries, including water transference and steam vessels in plants and electronic industries. Despite its desirable properties suchRead more

Iranian researchers succeeded in the production of a new drug delivery nano-system with applications in the treatment of cancer. Biocompatible and biodegradable polymers have been used in the production of the nanodrug, which decrease the toxicity of the drug carrier. The produced nano-drug has been successful in the treatment of breast tumor in animal sample. In the past decade, polymericRead more

The average heart beats 35 million times a year -- 2.5 billion times over a lifetime. Those beats must be precisely calibrated; even a small divergence from the metronomic rhythm can cause sudden death. For decades, scientists have wondered exactly how the heart stays so precisely on rhythm even though it contains so many moving parts. Now, researchers at theRead more

Iranian researchers from University of Mazandaran applied nanotechnology to produce a sensor to detect oxalic acid in natural samples. The sensor has a low detection limit and has been produced through a simple and cost-efficient method. The sensor has been produced and studied at laboratorial scale. Oxalic acid converts into oxalate in the body, and it prevents the sedimentation ofRead more

A study conducted over 20 years in the Los Angeles area has shown that the region's improving air quality has led to children having better functioning lungs, researchers said. The findings, which tracked 2,000 young people from age 11 to 15, were published in the New England Journal of Medicine. The scientists studied three cohorts of different children over twoRead more

A new study by researchers at the University of North Carolina has revealed just how incredibly easy it is for teenagers to procure electronic cigarettes online. Researchers found that just five out of 98 attempts by teenagers to purchase e-cigarettes from online retailers were thwarted by an age-verification mechanism. "Very few online vendors even gave the appearance of trying toRead more
