Researchers have demonstrated that saliva can be used for early detection of the risk of diseases associated with surplus body fat, an advance that may lead to better methods to diagnose chronic obesity-related ailments. The study, published in the journal Nutrition Research, identified uric acid in saliva as a reliable signature chemical to predict body fat percentages in teenagers. "The idea is to enable saliva to be more widely used as an alternative biological sample for clinical [...]

Researchers have identified for the first time the mechanism by which chronic stress causes hair colour loss, an advance that may lead to the development of novel drugs which can prevent the whitening of hair. In the study, published in the journal Nature, the scientists induced intense pain in special black mice for several weeks using a substance called resiniferatoxin, and turned the animals' fur completely white. "For the longest time it's been said that stress makes the hair [...]

Washington DC , Nov 13 : If you take too much stress while driving here's the news for you. Stress during driving is a risk factor for the development of cardiovascular diseases. A new study by Brazilian researchers suggest that cardiac overload due to the stress of driving in heavy traffic can be attenuated by listening to instrumental music. The results of the study were published in the journal Complementary Therapies in Medicine. Researchers at the University of Sao Paulo (USP) in [...]

The study also noted that the compound was effective against other species of Plasmodium An international team of researchers have found that a novel compound can halt the growth of the parasite Plasmodium falciparum known to cause malaria -- the deadly mosquito-borne disease which kills nearly 500,000 people every year across the world. The study, published in the journal Science, noted that the compound called TCMDC-135051 developed by the multinational pharmaceutical company [...]

What was once known as a single species of electric eel is actually three different species, with one of the newly classified organism producing the highest voltage discharge of any known animal, according to a study. The research, published in the journal Nature Communications, offers new insights into the origin and production of strong electric discharges in fishes. Electric eels belong to the knifefish family, and are closely related to catfish and carp than to other eel families, the [...]

Call it a shock discovery: DNA research has revealed two entirely new species of electric eel in the Amazon basin, including one capable of delivering a record-breaking jolt. The findings are evidence, researchers say, of the incredible diversity in the Amazon rainforest — much of it still unknown to science — and illustrate why it is so important to protect a habitat at risk from deforestation, logging and fires. “In spite of all human impact on the Amazon rainforest in the [...]

A new study has found that cannabidiol reduces aggressiveness arising out of isolation. Findings of the study were published in the journal 'Progress in Neuro-Psychopharmacology and Biological Psychiatry'. The mouse-model based study was performed by the scientists at the University of Sao Paulo's Ribeirao Preto Medical School (FMRP-USP) in Brazil. "Our study shows that cannabidiol can inhibit aggressiveness which it does by facilitating the activation of two receptors: [...]

Overweight and obese adolescents have similar increased risks of developing heart disorders, say researchers. "Until recently, overweight in adolescence wasn't considered as important a risk as obesity for the development of cardiovascular disease. We found the risks to be similar in both cases," said study lead author Vitor Engracia Valenti, Professor at Sao Paulo State University in Brazil. The study involved a small group of adolescents, aged between 10 and 17. The [...]

In a recent study, scientists have discovered that growth hormone (GH) plays an important role when it comes to losing and maintaining weight. According to the research published in the journal Nature Communications, GH stimulates skeletal maturation and linear bone growth, as well as helps maintain tissue and organs throughout life, also acts directly on the brain to conserve energy when the body loses weight. "Growth hormone has been known for decades, but our discovery shows it does a lot [...]
