Underwater explosions detonated by the US Navy to test the sturdiness of ships' hulls have provided seismologists with a test opportunity of their own: how much can we know about an underwater explosion from the seismic and acoustic data it generates?
A project by a research agency of the US Department of Defense could easily be misused for developing biological weapons.
Bombing raids by Allied forces during the WWII not only caused devastation on the ground but also sent shockwaves through Earth's atmosphere which were detected at the edge of space. University of Reading researchers have revealed the shockwaves produced by huge bombs dropped by Allied planes on European cities were big enough to weaken the electrified upper atmosphere -- the ionosphere -- above the UK, 1,000 km away. The results are published today in Annales Geophysicae.
New research in the INFORMS journal Operations Research has found a way to identify extremists, such as those associated with the terrorist group ISIS, by monitoring their social media accounts, and can identify them even before they post threatening content.
Semiautomatic rifles, which have been used in some of the largest shootings by individuals in US history, were banned in 1994 under the federal assault weapons ban, but that expired in 2004. This study compared the number of people wounded and killed during active shooter incidents (defined by the FBI as an individual killing or attempting to kill people in a confined or populated area) with, and without, semiautomatic rifles from 2000 through 2017.
New plume dispersal model alerts authorities how much time people have to flee after an attack.
According to new study of Syrian War in INFORMS journal Operations Research, unless there is a player so strong it can guarantee a win regardless of what others do, the likely outcome of multilateral war is a gradual stalemate that leads to mutual annihilation of all players.
First responders to major chemical exposure incidents in the United States can improve treatment protocols for at-risk casualties with better communication strategies, according to new analysis in Annals of Emergency Medicine.
New estimates published in The Lancet suggest that armed conflicts across the continent of Africa may have resulted in the deaths of as many as 5 million children aged under 5 years between 1995 and 2015, and claimed the lives of over 3 million infants aged one year or younger -- a burden several times higher than previous estimates.
Writing in advance of the Sept. 15 issue of Neural Computation, Beatrice Golomb, M.D., Ph.D., professor of medicine at University of California San Diego School of Medicine, says publicly reported symptoms and experiences of a 'mystery illness' afflicting American and Canadian diplomats in Cuba and China strongly match known effects of pulsed radiofrequency/microwave electromagnetic (RF/MW) radiation.
