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.
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.
