From engineered pandemics to city-toppling cyber attacks to nuclear annihilation, life on Earth could radically change, and soon. Scientists will forecast the fate of the planet at a press conference during the 2021 APS April Meeting.
Now that federal funding is flowing again for research on firearm injury prevention, some of the few already-funded researchers doing work in this area share new results and look ahead.
An invention from Purdue University innovators may provide a new option to use directed energy for biomedical and defense applications. The Purdue invention uses composite based nonlinear transmission lines (NLTLs) for a complete high-power microwave system, eliminating the need for multiple auxiliary systems.
Comparison of coda waves, the scattered waves that arrive after the direct waves of a seismic event, can be used to determine the relative locations of two underground explosions, according to a new study published in the open-access journal The Seismic Record.
Twenty percent of high school students have easy access to a handgun, according to a new study from the Colorado School of Public Health on the University of Colorado Anschutz Medical Campus. The findings highlight that it is relatively easy to access a handgun in Colorado for high school students. This finding, combined with the high prevalence of feeling sad or depressed and suicide attempts, is concerning for the safety of adolescents.
A Northwestern research team including Professors Justin Notestein and Peter Stair has demonstrated a new approach to chemical catalysis that results in higher yields of propylene -- the basis for many plastics -- using less energy.
At the heart of ice crystals, often, are aerosol particles onto which ice can form more easily than in the open air. It's a bit mysterious how this happens, though. New research shows how crystals of organic molecules, a common component of aerosols, can get the job done.
Using thin films -- no more than a few pieces of notebook paper thick -- of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow.
Using data collected in a NASA wind tunnel, researchers at the University of Illinois Urbana-Champaign replicated the hypersonic flow conditions of a compression ramp flow using Direct Numerical Simulation. The simulation was run on Frontera, a supercomputer system at the Texas Advanced Computing Center.
Pervoskite nanocrystals, a key component of emerging solar energy technology, are being used in Australia to develop a new, rapid-response detection mechanism for fumigants, pollutants and nerve agents. The technology, developed by the ARC Centre of Excellence for Exciton Science, Australia's national science agency CSIRO and the Department of Defence, could be used to protect emergency services, defence personnel and agricultural workers.
