Scientists identify mechanism by which inherited neurological disease causes muscle weakness in men

Researchers at University of California, San Diego School of Medicine have identified the mechanism by which a rare, inherited neurodegenerative disease causes often crippling muscle weakness in men, in addition to reduced fertility.

Neurons derived from human iPSC and grafted into rats after spinal cord injury produce cells

Building upon previous research, scientists at the University of California, San Diego School of Medicine and Veteran's Affairs San Diego Healthcare System report that neurons derived from human induced pluripotent stem cells (iPSC) and grafted into rats after a spinal cord injury produced cells with tens of thousands of axons extending virtually the entire length of the animals' central nervous system.

Small molecule may be able to convince damaged nerves to effectively rewire circuits

Frogs, dogs, whales, snails can all do it, but humans and primates can't. Regrow nerves after an injury, that is—while many animals have this ability, humans don't.

Kids are at risk of biological damage results from microwave radiation emitted by wireless devices

A scholarly article on wireless safety, published online in the Journal of Microscopy and Ultrastructure, reports that children and fetuses are the most at risk from neurological and biological damage that results from microwave radiation emitted by wireless devices, due to the higher rate of absorption of microwave radiation by children than by adults.

New approach for understanding auditory localization in patients with hearing aids under background noise

Patients with implanted artificial cochlea often complain that they cannot recognize speech well in natural environments, especially if background of noise is present.

New techniques offer insight into cell-by-cell makeup of organisms

In general, our knowledge of biology-and much of science in general-is limited by our ability to actually see things. Researchers who study developmental problems and disease, in particular, are often limited by their inability to look inside an organism to figure out exactly what went wrong and when.

Researchers study effect of alcohol on neural activity using fruit flies

Seeking eventual solutions to problems ranging from alcoholism, cancer and Alzheimer's to finding better ways to clean contact lenses and use Lego models to build bridges, University of Houston (UH) students devoted the summer to some serious scholarship.

Researchers at NIH-FEI Living Lab for Structural Biology achieve breakthrough biological results

FEI is pleased to announce that researchers at the NIH-FEI Living Lab for Structural Biology have achieved breakthrough biological results, using FEI’s Titan Krios™ transmission electron microscope (TEM), to elucidate the structural mechanism by which glutamate receptors participate in the transmission of signals between neurons in the brain. Their work is described in Nature, “Structural Mechanism of Glutamate Receptor Activation and Desensitization,” by Meyerson, et al., (DOI: 10.1038/nature13603), http://www.nature.com/nature/journal/vaop/ncurrent/full/nature13603.html .

Findings shed light on why PPARγ activators have side effect of promoting weight gain

The brain plays a central role in regulating appetite and whole-body metabolism. A protein known as PPARγ is important in the brain's control of food intake and body weight, but the identity of the neurons regulating this process has been unclear.

Study shows that mice can identify specific odors amid complex olfactory environments

For many animals, making sense of the clutter of sensory stimuli is often a matter or literal life or death. Exactly how animals separate objects of interest, such as food sources or the scent of predators, from background information, however, remains largely unknown.

Researchers uncover 3D structure of neuroreceptor

Neurons are the cells of our brain, spinal cord, and overall nervous system. They form complex networks to communicate with each other through electrical signals that are carried by chemicals.

Study: Spicy capsaicin can reduce risk of colorectal tumors

Researchers at the University of California, San Diego School of Medicine report that dietary capsaicin - the active ingredient in chili peppers - produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors.
