Observation of a magneto-Rayleigh-Taylor instability in magnetically collimated plasma jets

We present the direct experimental observation of the formation of a diamagnetic cavity and magneto-Rayleigh-Taylor (MRT) instability in a betaapprox1 high energy density plasma. Proton radiography is used to measure the two dimensional path-integrated magnetic field in a laser-produced plasma propagating parallel to a preimposed magnetic field. Flutelike structures, associated with the MRT instability, are observed to grow at the surface of the cavity, with a measured wavelength of 1.2 mm and growth time of 4 ns. These measurements are in good agreement with predictions of three dimensional magnetohydrodynamic simulations using the GORGON code.

Study uncovers broken mirror symmetry in the Fermi-liquid-like phase of a cuprate

Materials that exhibit superconducting properties at high temperatures, known as high-temperature superconductors, have been the focus of numerous recent studies, as they can be used to develop new technologies that perform well at higher temperatures. Although high-temperature superconductivity has been widely investigated, its underlying physics is not yet fully understood.

Paper types ranked by likelihood of paper cuts

Via testing with a skin stand-in, a trio of physicists at Technical University of Denmark has ranked the types of paper that are the most likely to cause a paper cut. In an article published in Physical Review E, Sif Fink Arnbjerg-Nielsen, Matthew Biviano and Kaare Jensen tested the cutting ability and circumstances involved in paper cuts to compile their rankings.

Reconfigurable sensor can detect particles 0.001 times the wavelength of light

In recent years, advances in photonics and materials science have led to remarkable developments in sensor technology, pushing the boundaries of what can be detected and measured. Among these innovations, non-Hermitian physics has emerged as a crucial area of research, offering new ways to manipulate light and enhance sensor sensitivity.

Research team develops atomic comagnetometer that suppresses noise by two orders of magnitude

A research team has discovered the Fano resonance interference effect between mixed atomic spins. They proposed a novel magnetic noise suppression technique, reducing magnetic noise interference by at least two orders of magnitude. The study was published in Physical Review Letters. The team was led by Prof. Peng Xinhua and Associate Prof. Jiang Min from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS)

United Therapeutics and 3D Systems shoot for 3D printed lung scaffold trials within five years

Biotechnology firm United Therapeutics has showcased what it claims to be the “world’s most complex 3D printed object” in partnership with 3D printer manufacturer 3D Systems at the recent LIFE ITSELF conference in San Diego.

The partners have produced a 3D printed human lung scaffold capable of demonstrating gas exchange in animal models, and are now planning to cellularize the scaffold with a patient’s own stem cells to create tolerable, transplantable human lungs.

“Last week, it was exciting to show the public our 3D printed human lung scaffold, but we’re thrilled to share that our 3D printed lung scaffolds are now demonstrating gas exchange in animal models,” said Dr. Martine Rothblatt, United Therapeutics’ Chairperson and CEO. “We are regularly printing lung scaffolds as accurately as driving across the United States and not deviating from a course by more than the width of a human hair.
