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.
The US Nuclear Regulatory Commission relied on faulty analysis to justify its refusal to adopt a critical measure for protecting Americans from nuclear-waste fires at dozens of reactor sites around the country, according to an article in the May 26 issue of Science magazine. Radioactivity from such a fire could force approximately 8 million people to relocate and result in $2 trillion in damages.
Clostridium botulinum is the bacterium that causes the neurointoxication, which produces one of the most potent toxins on earth and is classified as a potential bioterrorism threat. While no cure exists -- and botulism treatment options are limited -- a serendipitous discovery by scientists at The Scripps Research Institute (TSRI) may provide a new therapy that can stop the neurotoxin even in its more severe, advanced stages of action.
A single process for how a group of molecules called nucleotides were made on the early Earth, before life began, has been suggested by a UCL-led team of researchers.
A Florida State chemistry professor created a plutonium compound that behaves much more like lighter elements, giving scientists new information about how this element works.
Better medical responses to the accidental or intentional release of inhaled toxic chemicals are being developed, but the field faces considerable challenges, according to a new report by an international panel of experts. The report, 'Chemical Inhalation Disasters: Biology of Lung Injury, Development of Novel Therapeutics, and Medical Preparedness,' has been published online in the Annals of the American Thoracic Society.
Northeastern researchers Yung Joon Jung and Swastik Kar have developed a way to detect nuclear materials that far outpaces any existing method.
Pre-lithiated multiwalled carbon nanotubes and activated carbon (AC) materials were used as anode and cathode respectively for Lithium-ion capacitors (LICs). The pre-lithiatiation was performed using internal short circuit approach (ISC). The LIC showed excellent supercapacitor performance. The pre-lithiated MWCNTs have a potential application as anode for high performance Lithium-ion capacitors.
