Given the possible security vulnerabilities related to developments in synthetic biology -- a field that uses technologies to modify or create organisms or biological components -- a new report by the National Academies of Sciences, Engineering, and Medicine proposes a framework to identify and prioritize potential areas of concern associated with the field.
From the lab of City College of New York chemical engineer and Fulbright Scholar Teresa J. Bandosz comes a groundbreaking development with the potential to thwart chemical warfare agents: smart textiles with the ability to rapidly detect and neutralize nerve gas.
A research collaboration, led by professors Francesca Moresco (TUD) and Diego Peña (CiQUS), chemists from CiQUS prepared stable decacene precursors by solution chemistry, while physicists from TUD used these precursors to prepare decacene on a gold surface under ultra-high vacuum, in order to stabilize this extremely reactive compound.
A new light-trapping sensor, developed by a University at Buffalo-led team of engineers and described in an Advanced Optical Materials study, makes infrared absorption more sensitive, inexpensive and versatile. It may improve scientists' ability use to sleuth out performance-enhancing drugs in blood samples, tiny particles of explosives in the air and more.
Ebola virus infection can be detected in rhesus monkeys that survive the disease and no longer show symptoms, according to research published by Army scientists in today's online edition of the journal Nature Microbiology. The study sheds light on how the virus persists in certain areas of the body, and holds promise for the development of medical products to counter the disease in humans.
A new study by Kiran Bhaganagar, associate professor of mechanical engineering at The University of Texas at San Antonio, and her research group, Laboratory of Turbulence Sensing & Intelligence Systems, is taking a closer look at the damage caused by chemical attacks in Syria. The Syrian Civil War, ongoing since 2011, has seen hundreds of people killed through the use of chemical weapons.
With a sense of smell much greater than humans, dogs are considered the gold standard for explosive detection in many situations. But that doesn't mean there isn't room for improvement. In a study appearing in the ACS' journal Analytical Chemistry, scientists report on a new, more rigorous approach to training dogs and their handlers based on real-time analysis of what canines actually smell when they are exposed to explosive materials.
A research team, led by South Korea's Ulsan National Institute of Science and Technology has proposed a new method that might be used to detect nuclear hazards from up to a few hundred meters away.
Chemical weapons are nightmarish. In a millisecond, they can kill hundreds, if not thousands. But, in a study published in the ACS journal Chemistry of Materials, scientists report that they have developed a way to adhere a lightweight coating onto fabrics that is capable of neutralizing a subclass of these toxins -- those that are delivered through the skin. The life-saving technique could eventually be used to protect soldiers and emergency responders.
Scientists shed light on the neurological consequences of exposure to low-levels of nerve agents and suggest a drug that could treat some of the toxins' effects.
