As the debate continues on the ethics and therapeutic potential of embryonic versus mature stem cells, Medical College of Georgia researchers are exploring a third group of cells that appears critical to development and capable of making all major types of human tissue.
"VENT cells are a unique category of multi-potent cells," Dr. Douglas P. Dickinson, molecular biologist, says of this cell type that escapes from the bottom of the neural tube early in development, after the tube closes to form the brain.
VENT cells then travel along nerve paths, eventually getting ahead of the nerves, and dispersing throughout the body. "They travel in association with the cranial nerves to target tissues, disperse into those tissues, then, at what is perhaps an endpoint for their stay during development, they differentiate into the same cell type as their neighbors. So they potentially just vanish into the crowd," says Dr. Dickinson who first heard of these cells last year when their discoverer, MCG Developmental Biologist Paul Sohal, gave a lecture at the MCG School of Dentistry. Dr. Dickinson thought these cells might be used to establish a human cell line to enable his studies of the development and function of salivary glands.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
