Neuroscientists are taking inspiration from natural motor control to design new prosthetic devices that can better replace limb function. Researchers have tested a range of brain-controlled devices -- from wheelchairs to robots to advanced limbs -- that work with their users to intelligently perform tasks.
Scientists have found the genetic signature of enterovirus D68 in half of the California and Colorado children diagnosed with acute flaccid myelitis -- sudden, unexplained muscle weakness and paralysis -- between 2012 and 2014, with most cases occurring during a nationwide outbreak of severe respiratory illness from EV-D68 last fall.
The first study to investigate the relationship between eating fruit and vegetables containing pesticide residues and the quality of men's semen has shown a link with lower sperm counts and percentages of normally-formed sperm.
Date syrup – a thick, sweet liquid derived from dates that is widely consumed across the Middle East – shows antibacterial activity against a number of disease-causing bacteria, including Staphylococcus aureus and Escherichia coli.
For many, body odor is an unfortunate side effect of their daily lives. The smell is caused by bacteria on the skin breaking down naturally secreted molecules contained within sweat. Now scientists have studied the underarm microbiome and identified a unique set of enzymes in the bacterium Staphylococcus hominis that is effective at breaking down sweat molecules into compounds known as thioalcohols, an important component of the characteristic body odor smell.
Coast redwoods are famous for being the tallest trees in the world, but their height is not the only thing that sets them apart. Unlike most conifer trees, coast redwoods can reproduce by sprouting from cut stumps, fallen logs, and roots. Researchers from the University of California, Berkeley, are uncovering important information about patterns of coast redwood clones with a new DNA analysis method that could help forest management and preservation efforts.
Study co-author Gonedele Sere, on left, holds a cocoa plant found at an illegal farm in the Dassioko Forest Reserve in Ivory Coast. Researchers surveying for endangered primates in national parks and forest reserves of Ivory Coast found, to their surprise, that most of these protected areas had been turned into illegal cocoa farms, a new study reports.
Researchers have been fascinated for a long time by learning and memory formation, and many questions are still open. Bochum-based neuroscientists Prof Dr Denise Manahan-Vaughan and Dr Hardy Hagena have discovered a key building block for this complex process. A particular neurotransmitter receptor, namely the metabotropic glutamate receptor 5, is a switch for activating opposing forms of plasticity in the hippocampus, a brain region vital for memory forming. They reported in the current edition of "The Journal of Neuroscience".
The University of Texas Medical Branch at Galveston's Scott Weaver, globally recognized for his expertise in mosquito-borne diseases, has been studying chikungunya for more than 15 years. The mosquito-borne chikungunya virus has been the subject of increasing attention as it spreads throughout South America, Central America, the Caribbean and Mexico. This painful and potentially debilitating disease is predicted to soon spread to the U.S.
