Seashell-inspired Sandia shield protects materials in hostile environments
Word of an extraordinarily inexpensive material, lightweight enough to protect satellites against debris in the cold of outer space, cohesive enough to strengthen the walls of pressurized vessels experiencing average conditions on Earth and yet heat-resistant enough at 1,500 degrees Celsius or 2,732 degrees Fahrenheit to shield instruments against flying debris, raises the question: what single material could do all this?

Not all valved N95 masks are the same when filtering exhaled air, study finds
Using valved respirators to prevent the spread of COVID-19 has been discouraged due to concerns that valves do not effectively filter particles from exhaled air, but few studies actually have looked at this. Now, researchers report in Environmental Science & Technology Letters on their performance.
Experiments Measure Freezing Point of Extraterrestrial Oceans to Aid Search for Life
A planetary scientist worked with engineers to measure the physical limits of a liquid for salty water under high pressure. Results suggest where robotic missions should look for life on the ice-covered oceans of Jupiter's moon Europa and Saturn's moon Titan.
Particle Accelerators May Get a Boost from Oxygen
Scientists have developed a new theoretical model for preparing particle accelerator structures made of niobium metal. The model predicts how oxygen in the thin oxide layer on the surface of the niobium metal moves deeper into the metal during heat treatment. Tests indicate that the treatment should improve accelerator structure performance and make accelerators easier to build.

Face Shape Influences Mask Fit, Suggests Problems with Double Masking Against COVID-19
In Physics of Fluids, researchers use principal component analysis along with fluid dynamics simulation models to show the crucial importance of proper fit for all types of masks and how face shape influences the most ideal fit. They modeled a moderate cough jet from a mouth of an adult male wearing a cloth mask over the nose and mouth with elastic bands wrapped around the ears and calculated the maximum volume flow rates through the front of mask and peripheral gaps at different material porosity levels.
Facility for Rare Isotope Beams opens its doors to discovery
Michigan State University's Facility for Rare Isotope Beams (FRIB), a user facility for the U.S. Department of Energy Office of Science, opened its doors to discovery with a ribbon-cutting ceremony on 2 May. U.S. Secretary of Energy Jennifer M. Granholm and MSU President Samuel L. Stanley Jr., M.D., cut the ribbon to officially mark the start of FRIB's scientific mission.

The Source of the Aurora Borealis: Electrons Surfing on Alfven Waves
New experiments have shown the source of the aurora borealis. Researchers have demonstrated Alfven waves accelerating electrons under conditions that correspond to Earth's magnetosphere. The new experiments show that electrons "surf" on the electric field of the Alfven wave in a plasma. These electrons are the ultimate source of the light we call the aurora borealis.
Light-Infused Particles Go the Distance in Organic Semiconductors
Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors. They are both compatible with modern electronics but also move speedily, thanks to their photonic origins.
Fermilab Engineers Develop New Control Electronics for Quantum Computers That Improve Performance, Cut Costs
Quantum computing experiments now have a new control and readout electronics option that will significantly improve performance while replacing cumbersome and expensive systems. Developed by a team of engineers at Fermilab in collaboration with the University of Chicago, the Quantum Instrumentation Control Kit, or QICK for short, is easily scalable.
