Society faces threats through the malicious use of chemical, biological, radiological, nuclear and/or explosive (CBRNE) materials. The detection of illicit trafficking or other criminal acts, as well as many security and safety applications, call for novel material analysis techniques and instruments.
New research suggests that few people, if any, should be asked to leave their homes after a big nuclear accident, which is what happened in March 2011 following the Fukushima Daiichi nuclear disaster.
A brand-new theory of the opening moments during the Chernobyl disaster, the most severe nuclear accident in history, based on additional analysis is presented for the first time in the journal Nuclear Technology, an official journal of the American Nuclear Society.
Policymakers' efforts to reduce threats from improvised explosive devices (IEDs) should include greater oversight of precursor chemicals sold at the retail level -- especially over the Internet -- that terrorists, violent extremists, or criminals use to make homemade explosives, says a new report from the National Academies of Sciences, Engineering, and Medicine.
New technology from Dartmouth College harnesses electronic signals in a smart fabric to detect, capture, concentrate and filter toxic chemicals.
Wearable sensors are revolutionizing the tech-world, capable of tracking processes in the body, such as heart rates. They're even becoming fashionable, with many of them sporting sleek, stylish designs. But wearable sensors also can have applications in detecting threats that are external to the body. Researchers now report in ACS Sensors a first-of-its kind device that can do just that. And to stay fashionable, they've designed it as a ring.
Holographic images of free-flowing air particles may help climate change and biological weapons watchdogs better monitor the atmosphere, according to a recent Kansas State University study published in Nature's Scientific Reports. The images are made by two overlapping lasers that could be mounted on an unmanned aircraft to monitor the atmosphere.
University of Michigan researchers have developed a laser-based method that could be used to detect chemicals such as explosives and dangerous gases quickly and accurately.
Researchers have created a miniaturized, portable version of a tool now capable of analyzing Mars' atmosphere -- and that's just one of its myriad possible uses.
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.
