Firearms are a leading contributor to mortality in men aged 15-34 years in the USA, Mexico, Brazil, and Colombia, according to an observational study using national data for 106.3 million deaths, including 2.5 million firearm deaths in these 4 countries, published in The Lancet Public Health journal.
An increase in the number of firearm owners who live with children who lock up all their household guns could be associated with a reduction in youth firearm deaths by suicide and unintentional injury.
During WWI, William Lawrence Bragg led the development of an acoustic method to locate enemy artillery, work that was so successful that it was soon used widely throughout the British army. The method, known as sound ranging, was also adopted by the US Army when they joined the war, and earned Bragg a military decoration from the British armed forces. Bragg's story will be presented at the 177th ASA Meeting, May 13-17, 2019.
Researchers at King's College London, in collaboration with Northumbria University, have developed a new way of detecting homemade explosives which will help forensic scientists trace where it came from.
Radioactive carbon released into the atmosphere from 20th-century nuclear bomb tests has reached the deepest parts of the ocean, a new study in AGU's journal Geophysical Research Letters finds. Crustaceans in deep ocean trenches have incorporated this 'bomb carbon' into the molecules that make up their bodies.
Researchers with Nemours Children's Health System have shown the effectiveness of an adult tourniquet for use in children, according to a study published by the journal Pediatrics. While developed for adults, the military's Combat Application Tourniquet (CAT) is effective in controlling blood flow in children's arms and legs, as measured by Doppler pulse. This is the first, prospective study on the device's use in children.
A team of scientists has studied a catalyst that decomposes nerve agents, eliminating their harmful and lethal effects. The research was published Friday, April 19, in the Journal of Physical Chemistry Letters.
Debates over gun regulations make headlines across the world, but there's an underground operation for weapons that has drawn very little attention -- until now. Researchers from Michigan State University crept into the dark web to investigate how firearms are anonymously bought and sold around the world.
A team that studies how biological structures such as cactus spines and mantis shrimp appendages puncture living tissue has turned its attention to viper fangs. Specifically, the scientists wanted to know, what physical characteristics contribute to fangs' sharpness and ability to puncture? They report their findings in the Royal Society journal Biology Letters.
Purdue University researchers have developed a new design method to create soft robots that may help in caregiving for elderly family members.
