Scientists Report Direct Observation of the Dead-Cone Effect in Quantum Chromodynamics
Particle collisions produce quarks and gluons that interact in structured ways. Scientists have for the first time directly observed a predicted "dead cone" in this structure. This finding helps to confirm a feature of the theory of strong interactions, which explains how quarks and gluons form protons and neutrons.

Webb Follows Neon Signs Toward New Thinking on Planet Formation
In 2008 NASA's Spitzer Space Telescope found a protoplanetary disk unlike any other. The dusty disk of gas surrounding the young Sun-like star SZ Chamaeleontis (SZ Cha) was being pummeled by extreme ultraviolet radiation - something previously seen only in computer models, never in the real universe. Planets in this system would have more time to form than in a disk being evaporated by X-rays, which is the norm. However, when the James Webb Space Telescope followed up on SZ Cha, it found nothing out of the ordinary - no abundance of ultraviolet radiation. In a short space of cosmic time, conditions in SZ Cha's disk had changed, leaving astronomers to untangle meaning from the mismatched data and its implications for the formation of other solar systems.
NYU Tandon takes a quantum leap with new minor
NYU Tandon School of Engineering is poised to become one of an extremely select group of American universities offering an undergraduate program in quantum technology, situating it at the forefront of a fast-growing field in which high employer demand significantly outpaces available talent.
Society of Rheology Announces Winner of 2023 Journal of Rheology Publication Award
AIP Publishing and the Journal of Rheology congratulate Norman J. Wagner, Julie B. Hipp, and Jeffrey J. Richards, winners of the 2023 Journal of Rheology Publication Award for their paper, "Direct measurements of the microstructural origin of shear-thinning in carbon black suspensions." The winning paper demonstrates how shearing forces impact the microstructure responsible for viscosity in suspensions containing carbon black, a material used in energy storage. The paper also provides a quantitative master curve which relates the material's properties to how it may behave under stress.

Wearing Your Heart (Monitor) on Your Sleeve
By detecting cardiovascular ailments and helping assess overall cardiac health, wearable electrocardiograms save lives, not to mention exorbitant hospital care costs. In Applied Physics Reviews, researchers present a novel wearable electrocardiogram patch for enhanced point-of-care diagnostics. The study focused on the advantages of using active dry electrodes for ECG signaling, and they created a compact, lightweight, gel-free hexagonal-shaped ECG patch. The configuration was then integrated with wireless Bluetooth communication for remote sensing capabilities.
