In a new study in mice, a modified form of an innocuous chimpanzee virus has shown marked potency as a protective vaccine against HIV, itself believed to have crossed into the human population from chimpanzees sometime in the 1930s. The study, led by researchers at The Wistar Institute, appears in the February issue of the Journal of Immunology.
"Our results show this new vaccine is capable of inducing the kind of powerful immune response that we and others believe will be critical for controlling HIV infection," says Hildegund C.J. Ertl, M.D., professor and immunology program leader at The Wistar Institute, and senior author on the new study.
Given the history of HIV, Ertl emphasize the lengths to which she and her colleagues have gone to ensure that the new vaccine is completely safe. To eliminate the possibility of any contaminant - an HIV-like stowaway, for example - the vaccine is derived in the laboratory from a set of genetic instructions. Importantly, too, the genes that would be needed by the viral vaccine to replicate are deleted from those instructions.

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...
