Topics: Diversity in Science, Education, Medicine, Research, STEM AAAS will bring together a diverse group of professionals in science, technology, engineering, mathematics, and medicine (STEMM) to tackle the barriers to individuals entering and staying in careers in those fields. The first Multidisciplinary Working Group (MWG), called Empowering Career Pathways in STEMM (ECP), will focus onContinue reading “Multidisciplinarity…”

Flashing Droplets, Optical Tweezers…
Atomic analog: when a beam of light is shone into a water droplet, the light is trapped inside. (Courtesy: Javier Tello Marmolejo) Topics: Modern Physics, Optics, Quantum Mechanics, Quantum Optics, Research Light waves confined in an evaporating water droplet provide a useful model of the quantum behavior of atoms, researchers in Sweden and Mexico haveContinue reading “Flashing Droplets, Optical Tweezers…”
AAAS Science Awards…
Topics: Diversity in Science, Education, Research, STEM, Theoretical Physics The American Association for the Advancement of Science has announced the 2023 winners of eight longstanding awards that recognize scientists, engineers, innovators, and public servants for their contributions to science and society. The awards honor individuals and teams for a range of achievements, from advancing scienceContinue reading “AAAS Science Awards…”
Where No One Has Gone Before…
Images of six candidate massive galaxies, seen 500-800 million years after the Big Bang. One of the sources (bottom left) could contain as many stars as our present-day Milky Way but is 30 times more compact. Credit: NASA, ESA, CSA, I. Labbe (Swinburne University of Technology); Image processing: G. Brammer (Niels Bohr Institute’s Cosmic Dawn Center atContinue reading “Where No One Has Gone Before…”
Small Steps, Large Changes…
A vertical shock tube at Los Alamos National Laboratory is used for turbulence studies. Sulfur hexafluoride is injected at the top of the 5.3-meter tube and allowed to mix with air. The waste is ejected into the environment through the blue hose at the tube tower’s lower left; in the fiscal year 2021, such emissions madeContinue reading “Small Steps, Large Changes…”
Ripples, Waves, and Genesis…
Numerical simulation of the neutron stars merging to form a black hole, with their accretion disks interacting to produce electromagnetic waves. Credit: L. Rezolla (AEI) & M. Koppitz (AEI & Zuse-Institut Berlin) Topics: Black Holes, Cosmology, General Relativity, Gravity, Research Scientists have advanced in discovering how to use ripples in space-time known as gravitational wavesContinue reading “Ripples, Waves, and Genesis…”
Spooky Action Between Friends…
Credit: Petrovich9/Getty Images Topics: Entanglement, Particle Physics, Quantum Mechanics, Research, Theoretical Physics Reference: Albert Einstein colorfully dismissed quantum entanglement—the ability of separated objects to share a condition or state—as “spooky action at a distance.” Science.org For the first time, scientists have observed quantum interference—a wavelike interaction between particles related to the weird quantum phenomenon of entanglement—occurring betweenContinue reading “Spooky Action Between Friends…”
The Decline of Disruptive Science…
The proportion of disruptive scientific papers, such as the 1953 description of DNA’s double-helix structure, has fallen since the mid-1940s.Credit: Lawrence Lawry/SPL Topics: DNA, Education, Philosophy, Research, Science, STEM The number of science and technology research papers published has skyrocketed over the past few decades — but the ‘disruptiveness’ of those papers has dropped, accordingContinue reading “The Decline of Disruptive Science…”
Helium and Ukraine…
Topics: Chemistry, Instrumentation, Nuclear Magnetic Resonance, Physics, Research Scientists who need the gas face tough choices in the face of reduced supply and spiking prices. Helium supplies, already dicey, got worse this past week when production shut down in Arzew, Algeria. The curtailment joins ongoing disruptions in supplies from Russia and the US Federal Helium Reserve as wellContinue reading “Helium and Ukraine…”
Things We’ve Lost…
Topics: COVID-19, Existentialism, Physics, Research An excerpt. The longer article piece is at the link following. The COVID-19 pandemic has not only killed a large number of people—approximately 5.5 million worldwide at the time Physics Today went to press in mid-January—it has also disrupted life in a fundamental, nonperturbative manner, forcing large-scale changes in human behavior fromContinue reading “Things We’ve Lost…”
