Simulating the shear destruction of red blood cells: Devices used to treat heart failure can create…
Many medical devices for treating heart failure generate nonphysiological shear flow. This can trigger the destruction of red blood cells after implantation of ventricular assist devices (VADs), artificial heart valves, vascular stents, or…
Particle radioactivity linked to pollution-associated heart attack and stroke death: Radon in air…
Particle radioactivity, a characteristic of air pollution that reflects the colorless, odorless gas radon found in fine particulate matter (PM2.5) air pollution, enhances PM2.5 toxicity and increases risk of death from cardiovascular…
Researchers uncover how to 3D-print one of the strongest stainless steels: Insights revealed by a…
For airliners, cargo ships, nuclear power plants and other critical technologies, strength and durability are essential. This is why many contain a remarkably strong and corrosion-resistant alloy called 17-4 precipitation hardening (PH)…
Shape Of Coronavirus Affects Its Transmission, Says Study
Images of the coronavirus, SARS-CoV-2, have been imprinted in our brains since the commencement of the COVID-19 pandemic. However, the way we commonly visualise the virus, as a spherical with spikes, is not entirely true. Microscope images…
Signs of saturation emerge from particle collisions at RHIC: Suppression of a telltale sign of…
Nuclear physicists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) -- a U.S. Department of Energy Office of Science user facility at DOE's Brookhaven National Laboratory -- have new evidence that particles called…
Particle phase chemistry enables soot to better seed clouds: New study challenges current…
Particle phase photochemical oxidation of polycyclic aromatic hydrocarbons on soot can produce substantial amount of highly unsaturated and oxygenated organic aerosol. That changes soot to better serve as cloud condensation nuclei and…
Research reveals why tackling particle pollution leads to rise in photochemical smog
Researchers from the University of York have discovered why reducing particle pollution is actually increasing surface ozone pollution in some emerging economies, negatively impacting health, ecosystems and agriculture.
The findings,…
