Taming the sounds of a noisy hospital room

Posted: 29 Jun 2020 02:25 PM PDT

Hospitals can get noisy, especially intensive care units, and the life-saving electronic machines monitoring patient vital signs are making most of the racket. Mike Rayo, an assistant professor of integrated systems engineering at The Ohio State University, is working to improve and organize the cacophony to help caregivers and patients alike. For almost a decade, […]
Understanding of relaxor ferroelectric properties could lead to many advances

Posted: 29 Jun 2020 02:24 PM PDT

A new fundamental understanding of polymeric relaxor ferroelectric behavior could lead to advances in flexible electronics, actuators and transducers, energy storage, piezoelectric sensors and electrocaloric cooling, according to a team of researchers at Penn State and North Carolina State. Researchers have debated the theory behind the mechanism of relaxor ferroelectrics for more than 50 years, […]
Producing a gaseous messenger molecule inside the body, on demand

Posted: 29 Jun 2020 02:21 PM PDT

Nitric oxide is an important signaling molecule in the body, with a role in building nervous system connections that contribute to learning and memory. It also functions as a messenger in the cardiovascular and immune systems. But it has been difficult for researchers to study exactly what its role is in these systems and how […]
Still Confused About Masks? Here’s the Science Behind How Face Masks Prevent Coronavirus

Posted: 29 Jun 2020 12:35 PM PDT

As states reopen from stay-at-home orders, many, including California, are now requiring people to wear face coverings in most public spaces to reduce the spread of COVID-19. Both the Centers for Disease Control and Prevention (CDC) and the World Health Organization now recommend cloth masks for the general public, but earlier in the pandemic, both organizations recommended just the […]
“Where are My Keys?” and Other Memory-Based Choices Probed in the Brain

Posted: 29 Jun 2020 12:30 PM PDT

The encoding and retrieval of memories occurs in the lower-middle portion of the brain in a region called the medial temporal lobe, which includes the hippocampus. Decision-making processes involve a region at the front of the brain called the medial frontal cortex. “The ability to flexibly engage and utilize our memories to make decisions depends […]
First observation of rare events producing three massive force carriers simultaneously

Posted: 29 Jun 2020 12:27 PM PDT

Modern physics knows a great deal about how the universe works, from the grand scale of galaxies down to the infinitesimally small size of quarks and gluons. Still, the answers to some major mysteries, such as the nature of dark matter and origin of gravity, have remained out of reach. Caltech physicists and their colleagues […]
