Danish researchers have addressed an international environmental problem by developing a model that can predict how certain chemicals amplify the effects of pesticides and other chemical compounds. Pesticide expert hopes that it will make environmental legislation easier.
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.
The western corn rootworm continues to be on the rise in Europe. Why attempts to biologically target this crop pest by applying entomopathogenic nematodes have failed, can be explained by the amazing defense strategy of this insect. A new study shows that the rootworm larvae are able to sequester plant defense compounds from maize roots in a non-toxic form and can activate the toxins whenever they need them to protect themselves against their own enemies.
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.
Military service exposes soldiers to a unique set of physical challenges, including toxic chemicals and traumatic brain injury, which can have profound effects on their health and well-being. New research examines the effects of military-related brain disorders and possible paths toward treatment, as well as a potential way to harness our brain's learning capabilities to better train pilots. The studies were presented today at Neuroscience 2017, the annual meeting of the Society for Neuroscience.
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.
John Innes Centre researchers used a study of the plant-growth promoting bacterium Pseudomonas fluorescens to develop an advanced analysis method which, they hope, will increase our capacity to understand plant and human diseases.
