Fruit flies stand in for mosquitoes in Johns Hopkins study Fire up the citronella-scented tiki torches, and slather on the DEET: Everybody knows these simple precautions repel insects, notably mosquitoes, whose bites not only itch and irritate, but also transmit diseases such as West Nile virus, malaria and dengue. Now, Johns Hopkins scientists have discovered what it is in the bugs' molecular makeup that enables citronellal (the aromatic liquid used in lotions, sprays and candles) and DEET,...

New research in the Journal of General Physiology helps explain how the body's "flight-or-fight" response is mediated. The study, which may provide new answers to the question of how the heart pacemaker"”the sinoatrial (SA) node"”is regulated, appears online on August 16 (www.jgp.org). When the body goes into "flight-or-flight" response as a reaction to stress, the increased firing rate of the SA node increases the heart rate and cardiac output to deliver more oxygen and nutrients...

TEL AVIV, Israel, August 9, 2010 /PRNewswire/ -- A new study conducted in the department of Biochemistry and Molecular Biology at Tel Aviv University (TAU) elucidates the way in which toxic, yet essential, copper ions enter human cells. As a chemotherapy drug presumably enters the cells in a similar manner, the results of this study pave the way for the development of improved chemotherapeutic drugs. The groundbreaking work was published in the leading American scientific journal PNAS...

For those with high blood pressure, chili peppers might be just what the doctor ordered, according to a study reported in the August issue of Cell Metabolism, a Cell Press publication. While the active ingredient that gives the peppers their heat"”a compound known as capsaicin"”might set your mouth on fire, it also leads blood vessels to relax, the research in hypertensive rats shows. "We found that long-term dietary consumption of capsaicin, one of the most abundant components in...

Cold sensing neural circuits in newborn mice take around two weeks to become fully active, according to a new study. The finding adds to understanding of the cold sensing protein TRPM8 (pronounced trip-em-ate), first identified in a Nature paper in 2002 by USC College professor David McKemy. McKemy's study, published online by Neuroscience, shows that the cold sensing circuit starts to develop in utero but does not mature until well after birth. "About three or four days before the animal is...

A mutation that enhances the function of a specific ion channel has been identified as the cause of a rare inherited pain disorder. The research, published by Cell Press in the June 10 issue of the journal Neuron, proposes a potential treatment for the disorder and may lead to a better understanding of chronic pain in humans. There are multiple human neurological disorders that have been linked with mutations in ion channels. Ion channels are proteins that span the cell membrane and govern...

Walter and Eliza Hall Institute scientists have made a significant advance in understanding how potassium channels, which permit the flow of electric currents central to many of the body's biological processes, control the flow of these currents. Dr Jacqui Gulbis from the institute's Structural Biology division, who led the research, said previous studies that had identified what potassium channels look like had provided valuable insights into how they work. However, the way the channels open...
