Brett Smith for redOrbit.com - Your Universe Online After numerous research studies raised questions over its safety, several states and countries began banning the sale of products containing bisphenol A (BPA), prompting companies in the plastics industry to begin producing products that were “BPA free.” However, a new study from the University of Texas Medical Branch at Galveston (UTMB) shows that a widely used BPA substitute, bisphenol S (BPS), has the same negative...

Jackson Laboratory researchers led by Associate Professor Zhong-wei Zhang, Ph.D., have provided direct evidence that a specific neurotransmitter receptor is vital to the process of pruning synapses in the brains of newborn mammals. Faulty pruning at this early developmental stage is implicated in autism-spectrum disorders and schizophrenia. The definitive evidence for N-methyl-D-aspartate receptor (NMDAR) in pruning has eluded researchers until now, but in research published in the...

The ability of the eye of a fruit fly (Drosophila melanogaster) to respond to light depends on a delicate ballet that keeps the supply of light sensors called rhodopsin constant as photoreceptors turn on and off in response to light exposures, said researchers from Baylor College of Medicine (www.bcm.edu) and the Jan and Dan Duncan Neurological Research Institute (http://www.nri.texaschildrens.org/) at Texas Children's Hospital in an article that appears online in the journal PLOS Biology...

Using a super-resolution fluorescent microscope, medical scientists are a step closer to understanding why and how human immune cells decide to activate or not, thus enabling or preventing disease taking hold in the body. Professor Katharina Gaus and her team at the Centre for Vascular Research based at UNSW´s Lowy Cancer Research Centre used some of the most advanced super-resolution optical microscope technology available anywhere in the world to see changes in individual proteins...

Researchers at the University of Geneva, Switzerland, demonstrate that the receptors that bind the toxin of this bacterium control how cell division is oriented Anthrax uses a receptor on the surface of cells to inject its lethal toxins. However, the physiological function of this receptor, named Anthrax Toxin Receptor 2a (Antxr2a), remained unknown until now. A team led by Marcos Gonzalez-Gaitan, a professor at the University of Geneva (UNIGE), Switzerland, in collaboration with Gisou van...
