UrduQuantum entanglement occurs when two particles appear to communicate without a physical connection, a phenomenon Albert Einstein famously called “spooky action at a distance.” Nearly 90 years later, a team led by the U.S. Department of Energy’s Oak Ridge National Laboratory demonstrated the viability of a “quantum entanglement witness” capable of proving the presence of entanglement between magnetic particles, or spins, in a quantum material.

Laboratory Will Illuminate Formation, Composition, Activity of Comets
In Review of Scientific Instruments, researchers have developed a laboratory to simulate comets in space-like conditions. The goal of the Comet Physics Laboratory is to understand the internal structure of comets, as well as how their constituent materials form and react. Many of the lab’s future experiments will involve creating sample comet materials with differing compositions. By testing those materials in the space-like chamber, the researchers can compare each sample to what has been observed on actual comets.

“Greening” Biomaterials and Scaffolds Used in Regenerative Medicine
In the biomaterials industry, electrospinning is a ubiquitous fabrication method used to produce nano- to microscale fibrous meshes that closely resemble native tissue architecture.

But now, Columbia Engineering researchers report that they have developed a “green electrospinning” process that addresses those challenges, from managing environmental risks of volatile solvent storage and disposal at large volumes to meeting health and safety standards during both fabrication and implementation.
