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 [...]

A new species of fungus gnat (Keroplatidae) has been discovered by a group of Brazilian researchers. According to them, the new species' larvae emit blue light. The small fly inhabits an Atlantic Rainforest reserve in São Paulo State. This is the first record of a blue bioluminescent species in the Neotropics. Many bioluminescent insects and fungi have been studied in the region, but all emit green, yellow or red light. The new species has been named Neoceroplatus betaryiensis and is [...]

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 GlaxoSmithKline can eliminate the mosquito-borne parasite in all the stages of its lifecycle. 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 [...]

Theoretical paper published in Monthly Notices of the Royal Astronomical Society proposes an explanation for the dynamics of the ring around Haumea, a dwarf planet located beyond Pluto's orbit Discovered in 2004, Haumea is a dwarf planet located beyond Pluto's orbit in a region of the Solar System called the Kuiper Belt. Pluto was demoted from the category of fully fledged planets in 2006 because of the discovery of Haumea and other dwarf planets. Haumea was officially recognized as a [...]

Research conducted in recent years has suggested that posttranslational histone modification causes alterations in gene expression without affecting the DNA sequence. Curcumin is widely used to impart color and flavor to food, but scientists have discovered that this yellow powder derived from the roots of the turmeric plant (Curcuma longa) can also help prevent or combat stomach cancer. The study by researchers at the Federal University of São Paulo (UNIFESP) and the Federal [...]

According to the research published in the journal Nature Communications, scientists have discovered that growth hormone (GH) plays an important role when it comes to losing and maintaining weight. 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 more than was [...]
