Origami Lattice Paves the Way for New Noise-Dampening Barriers on the Road

JAP017737-Thota-OrigamiSoundBar.jpg

Researchers at the University of Michigan have brought a new method into the sound-dampening fold, demonstrating an origami lattice prototype that can potentially reduce acoustic noise on roadways. The technique allows researchers to selectively dampen noise at various frequencies by adjusting the distance between noise-diffusing elements. They report their work this week in the Journal of Applied Physics.

Active Sieving Could Improve Dialysis and Water Purification Filters

Physicists in France have proven theoretically that active sieving, as opposed to its passive counterpart, can improve the separation abilities of filtration systems. These new views on how active sieving could improve systems such as those used in water purification and dialysis were reported this week in The Journal of Chemical Physics. Active sieving also has the potential to filter molecules based on movement dynamics, opening up a whole new avenue in the field of membrane science based on the ability to tune osmotic pressure.

The Drop That's Good to the Very End

POF013710-Charalampous-drop-sphere-19.jpg

Two researchers in the U.K., using laser-flash photography of microscopic droplet-particle collisions, have discovered that water droplets still have liquid tricks to reveal. Previous research has primarily examined droplet collisions with flat surfaces, such as a wall, but this research team examined the less studied case of a droplet having a head-on collision with a solid, spherical particle. They discuss their work in this week’s Physics of Fluids.

Force Field Analysis Provides Clues to Protein-Ion Interaction

JCP031791-Ren-AMOEBAforcefield_image1.jpg

The importance of proteins and metal ion interactions is well understood, but the mechanistic interactions between the two are still far from a complete picture. Researchers at the University of Texas at Austin, are working to quantitatively describe protein-ion interactions using what is called an atomic multipole optimized energetics for biomolecular applications force field. They describe their work in this week’s The Journal of Chemical Physics.

Johns Hopkins Finds Training Exercise That Boosts Brain Power

One of the two brain-training methods most scientists use in research is significantly better in improving memory and attention. It also results in more significant changes in brain activity.

New Study: Nearly Half of U.S. Medical Care Comes From Emergency Rooms

Nearly half of all US medical care is delivered by emergency departments, according to a new study by researchers at the University of Maryland School of Medicine. In recent years, the percentage of care delivered by emergency departments has grown. The paper highlights the major role played by emergency rooms in U.S. health care.

Clues to the Innate Drug Resistance of a Cocoa-Fermenting Pathogen

Webp.net-resizeimage-12.jpg

At first glance, the yeast Candida krusei seems as innocuous as microbes come: it’s used for fermenting cocoa beans and gives chocolate its pleasant aroma. But it’s increasingly being found as a pathogen in immunocompromised patients—and C. krusei infections aren’t always easy to cure.
