Drops Wear Different "Crowns"

May 23, 2023

A study of drops falling on a thin liquid film finds that splash behavior depends on film thickness—a result that could impact our understanding of stalagmite formation.

Superconductor Vortices Visible as Stripes

May 30, 2023

An unusual kind of superconductor harbors magnetic vortices that researchers predict should be readily observable thanks to the striped configurations they adopt.

Angle and Friction Matter for Table Tennis Spin

May 26, 2023

The angle of incidence and the friction of the surface are the only factors that impact the spin of a table tennis ball after it collides with a rigid surface.

"Shuttled" Ions Stay Quantum

May 26, 2023

Researchers move an individual Mg+ ion more than 100,000 times between different sites in a trapping array without dropping it or ruining its quantum coherence.

synopsis

Static Electrons in Flat-Band Nonequilibrium Superconductors

May 25, 2023

Single electrons stay stationary in superconductors with "flat-band" electronic structures, which could lead to low-energy-consumption devices made from such materials.

Gravity Alters the Shape of an Evaporating Droplet

May 24, 2023

Whether sitting or hanging, the surface of a protein-containing droplet changes as the water escapes, an effect researchers link to the pull of gravity.

synopsis

Curved-Laser Demonstration for a Higher-Energy Laser Accelerator

May 23, 2023

A curved "laser wakefield accelerator" could boost the acceleration potential of a multistage version of this device.

Squeezable Metal Offers a Greener Approach to Refrigeration

May 30, 2023

A system built around a metal that gains and loses heat when compressed could lead the way to the commercialization of chemical-free refrigeration technology.

Survey Finds Cheating Is Common in Graduate School

May 25, 2023

In a survey of 244 engineering graduate students, one fifth admit to cheating or committing some form of research malpractice during their studies.

Research News

Researchers Recreate a Nearsighted Eye

May 23, 2023

A new device can recreate the refractive errors of a myopic eye—one that displays nearsightedness—allowing scientists to test lenses designed to slow down the progression of the condition.
