A Textbook Dirac Semimetal
Researchers have synthesized a chalcogenide compound that has the electronic structure of an ideal Dirac semimetal—which could facilitate the study of this exotic class of materials. Read More »
Bond Density Not Strength Controls Polymer Stickiness
Experiments show that the sticky behavior of so-called associative polymers is controlled by the density of bonding structures, contradicting theoretical predictions. Read More »
Realizing the Einstein-Podolsky-Rosen Paradox for Atomic Clouds

Squeezable Metal Offers a Greener Approach to Refrigeration
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. Read More »
Superconductor Vortices Visible as Stripes
An unusual kind of superconductor harbors magnetic vortices that researchers predict should be readily observable thanks to the striped configurations they adopt. Read More »
Angle and Friction Matter for Table Tennis Spin
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. Read More »
