Researchers scrambling to combat a virulent form of bird flu that could mutate into a form easily spread among humans should consider developing vaccines based on DNA, according to British biochemical engineers. DNA vaccines, they say, can be produced more rapidly than conventional vaccines and could possibly save thousands of lives if a global influenza outbreak occurs.
A DNA-based vaccine could be a potent weapon against this emerging threat, particularly if enough conventional vaccine isnt available, according to Peter Dunnill, DSc., and his colleagues at University College London. However, they caution that any DNA vaccine should only be used as needed to slow the spread of the disease because the technique is largely untested in humans. The analysis appears in the November-December issue of the journal Biotechnology Progress, a co-publication of the American Chemical Society and the American Institutes of Chemical Engineers.
The avian virus, H5N1, has spread among birds throughout Southeast Asia and has been recently detected in Eastern Europe. The virus has killed more than 60 people in Asia since 2003 and forced the slaughter of millions of birds. There are no confirmed cases of human-to-human transmission of this flu, but that could change as the virus continues to mutate, Dunnill says.

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...
