A team of scientists from Johannes Gutenberg University in Mainz and the Max Planck Institute for Chemical Ecology in Jena have now found that beewolves, unlike humans, do not face the problem of antibiotic resistant pathogens. These insects team up with symbiotic bacteria which produce up to 45 different antibiotic substances to protect their offspring against mold fungi. This antibiotic cocktail has remained surprisingly stable since the symbiosis emerged, about 68 million years ago.
Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person's breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best 'chemical noses' even more sensitive.
In a new study, USC Viterbi School of Engineering professors used computer-based models to identify mechanisms or 'strategies' used by bacterial spores to evade attack from extreme temperatures, chemicals and radiation. Using complex mathematical techniques to examine spores at the molecular level, the team also determined the optimal conditions for killing harmful bacteria.
An joint research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced the Hybrid-SOEC system with highest reported electrochemical performance in hydrogen production.
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.
