Brief, acute psychological stress promoted healing in mouse models of three different types of skin irritations, in a new study. Scientists found that healing was brought about by the anti-inflammatory effects of glucocorticoids -- steroid hormones -- produced by the adrenal glands in response to stress. "Under chronic stress, these same naturally-occurring steroids damage the protective functions of normal skinRead more

- Iranian researchers from Isfahan University of Technology designed a new non-enzyme nanosensor that has applications in the measurement of blood glucose. Results of the research can meet the needs of hospitals and diagnosis laboratories to a cheap, quick and accurate sensor for the measurement of blood sugar in patients. At present, commercial sensors to detect glucose include enzyme electrochemicalRead more

 Iranian researchers from Dezful Branch of Islamic Azad University managed to produce ceramic nanocrystals through a simple and cheap method. This process takes place at low temperature (ambient temperature to 50° C), and it produces very pure crystals free from carbonate phases without producing any bi-products. Nanocrystals play a key role in the production of nanostructured electronic products. Since theRead more

Iranian researchers produced electromagnetic nanocomposite made of iron oxide and polyfuran magnetic nanoparticles and succeeded in the synthesis of electrochemical biosensor sensitive to hydrogen peroxide. By producing the sensor, the researchers overcame some problems, including low conductivity and low thermal stability of polyfuran. Cardiac disorders increase hydrogen peroxide in body’s tissues, which damages inner layer of arteries and causes bloodRead more

Researchers showed that electromagnetic stimulation can alter brain organization, which may make your brain work better. In results from a study published in the Journal of Neuroscience, researchers from The University of Western Australia and the Université Pierre et Marie Curie in France demonstrated that weak sequential electromagnetic pulses (repetitive transcranial magnetic stimulation -- or rTMS) on mice can shiftRead more

A groundbreaking study by Australian and Chinese researchers has found a link between depression sufferers and the last night use of social media tools. The joint study by the Australia National University (ANU) and China's Harbin Institute of Technology (HIT) analyzed data from Chinese social media site Weibo to predict potential depression among users. The results, released Wednesday, suggest theRead more

 When it comes to testosterone -- the hormone associated with all things manly -- and human society, less is apparently more. Researchers found a correlation between shrinking levels of testosterone in humans and the expansion and sophistication of human societies. Authors of the new paper -- published this week in the journal Current Anthropology -- say a reduction of testosteroneRead more

Harry Potter didn't really solve racism, but new research suggests those who read the Harry Potter books and identify with the main character are more likely to empathize with immigrants, homosexuals and refugees. In other words, Harry Potter teaches tolerance -- kind of. The study into Harry Potter's liberalizing effects -- published recently in the Journal of Applied Social PsychologyRead more
