At a recent seminar for potential investors and licensees, part of the Sandia Technology Showcase series, Sandia bioscientists presented eight ready-to-license technologies in three key areas: medical diagnostics, biosurveillance and therapeutics and drug discovery. "As a national laboratory, Sandia works at the frontier of biology, doing research and development at the precompetitive research stage," explained Malin Young, director of Sandia's Biological and Engineering Sciences Center. "We're applying new knowledge of how pathogens interact with hosts to reach breakthroughs that private companies can then build on to create innovative products to detect and fight disease." Victoria VanderNoot, a biosciences research manager, said the private sector needs insight into what is happening at the national labs. "We're addressing that barrier by … Continue reading →

Contact Information Available for logged-in reporters only Newswise March 19, 2015(Bronx, NY)Scientists at Albert Einstein College of Medicine of Yeshiva University and their international collaborators have developed a novel fluorescence microscopy technique that for the first time shows where and when proteins are produced. The technique allows researchers to directly observe individual messenger RNA molecules (mRNAs) as they are translated into proteins in living cells. The technique, carried out in living human cells and fruit flies, should help reveal how irregularities in protein synthesis contribute to developmental abnormalities and human disease processes including those involved in Alzheimers disease and other memory-related disorders. The research will be published the March 20 edition of Science. Weve never been able to pinpoint exactly when and where mRNAs are translated into proteins, said study co-leader Robert H. Singer, Ph.D., professor and co-chair of anatomy and structural biology and co-director of the Gruss Lipper Biophotonics Center at Einstein. This capability will be critical for studying the molecular basis of disease, for example, how dysregulation of protein synthesis in brain cells can lead to the memory deficits that occur in neurodegeneration. Dr. Singer also holds the Harold and Muriel Block Chair in Anatomy & Structural Biology … Continue reading →

The human gut is a remarkable thing. Every week the intestines regenerate a new lining, sloughing off the equivalent surface area of a studio apartment and refurbishing it with new cells. For decades, researchers have known that the party responsible for this extreme makeover were intestinal stem cells, but it wasn't until this year that Scott Magness, PhD, associate professor of medicine, cell biology and physiology, and biomedical engineering, figured out a way to isolate and grow thousands of these elusive cells in the laboratory at one time. This high throughput technological advance now promises to give scientists the ability to study stem cell biology and explore the origins of inflammatory bowel disease, intestinal cancers, and other gastrointestinal disorders. But it didn't come easy. One Step Forward . . . When Magness and his team first began working with intestinal stem cells some years ago, they quickly found themselves behind the eight ball. Their first technique involved using a specific molecule or marker on the surface of stem cells to make sure they could distinguish stem cells from other intestinal cells. Then Magness's team would fish out only the stem cells from intestinal tissues and grow the cells in Petri … Continue reading →

Courtney Passow, a doctoral student in biology from Round Rock, Texas, will attend the 65th Lindau Nobel Laureate Meeting in Lindau, Germany. Passow is one of 672 young scientists selected worldwide to attend the meeting. The Council for the Lindau Nobel Laureate Meetings invited Passow to attend the meeting, which occurs June 28 to July 3. Mars Inc. is sponsoring Passow and covering her travel expenses. While attending the meeting, Passow will interact with Nobel laureates, graduate students and postdoctoral researchers -- all in the areas of physics, physiology, medicine and chemistry. "These are some of the top researchers around the world and it's a great opportunity to not only make contact with them but to also look for potential collaborations," Passow said. "While physics and chemistry are not my primary areas of research, getting to meet with researchers in these … Continue reading →
