Wearable, Inexpensive Robotic Sleeve for Lymphedema Treatment
In Biomicrofluidics, researchers developed a soft robotic sleeve controlled with a microfluidic chip that reduces cost, weight, and power consumption for treatment of lymphedema. The prototype is more portable than previous devices, and the underlying mechanisms can extend to other treatments, such as prosthetics. The microfluidic chip has 16 channels, each with a different resistance. The differing resistances create a time delay between the flow through each channel, causing balloons in the sleeve to sequentially inflate and push fluid upwards, out of the arm.

Irvine, Calif., May 4, 2022 - Two University of California, Irvine researchers have been elected to the National Academy of Sciences, one of the world's most respected scientific organizations. Svetlana Jitomirskaya, Distinguished Professor of mathematics, and Krzysztof Palczewski, Distinguished Professor of ophthalmology, are among 120 U.
FSU astrophysicist chosen for key role in international science collaboration mapping remnant light from the Big Bang
A Florida State University cosmologist has been selected to co-lead a Department of Energy and National Science Foundation project investigating the faint leftover radiation from the Big Bang known as the cosmic microwave background, or CMB.FSU Associate Professor of Physics Kevin Huffenberger and University of Chicago Associate Professor of Astronomy and Astrophysics Jeff McMahon will serve as co-spokespersons for the so-called CMB-S4 science collaboration, a project to provide insight into the most energetic processes in the universe and probe physics from the universe to subatomic particles.
Researchers Manipulate Demographic of Bacterial Community with Novel Electronic Technology
Using second-long electrical shocks, UC San Diego scientists discovered they could control the types of cells in a community of bacteria. Being able to direct the ratio of cells holds implications for settings spanning agriculture to health care, where antibiotic resistance is a significant threat.
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.
Machine Learning Program for Games Inspires Development of Groundbreaking Scientific Tool
Scientists have developed a groundbreaking AI-based algorithm for modeling the properties of materials at the atomic and molecular scale. It should greatly speed up materials discovery.
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.
