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…”
Cold Atmospheric Plasmas…
Topics: Applied Physics, Chemistry, Physics, Plasma, Research ABSTRACT Cold atmospheric plasmas have great application potential due to their production of diverse types of reactive species, so understanding the production mechanism and then improving the production efficiency of the key reactive species are very important. However, plasma chemistry typically comprises a complex network of chemical speciesContinue reading “Cold Atmospheric Plasmas…”
Our Flexible Molecule…
Topics: Biology, DNA, Physics, Polymer Science, Research DNA molecules are not fixed objects – they are constantly getting broken up and glued back together to adopt new shapes. Davide Michieletto explains how this process can be harnessed to create a new generation of “topologically active” materials. Call me naïve, but until a few years ago I hadContinue reading “Our Flexible Molecule…”
COVID, and Math…
Topics: Biology, Chemistry, COVID-19, Mathematics, Physics The year 2020 has been defined by the COVID-19 pandemic: The novel coronavirus responsible for it has infected millions of people and caused more than a million deaths. Like HIV, Zika, Ebola, and many influenza strains, the coronavirus made the evolutionary jump from animals to humans before wreaking widespreadContinue reading “COVID, and Math…”
Nobel Prize in Physics…
Topics: Nobel Laureate, Nobel Prize, Physics The Nobel Prize in Physics 2020 was divided, one half awarded to Roger Penrose “for the discovery that black hole formation is a robust prediction of the general theory of relativity”, the other half jointly to Reinhard Genzel and Andrea Ghez “for the discovery of a supermassive compact objectContinue reading “Nobel Prize in Physics…”
Cats, Llamas, Coronavirus Therapies…
Topics: Chemistry, COVID-19, Physics, Research As the world anxiously awaits development of one or more vaccines to tame the SARS-CoV-2 virus, other research continues at a feverish pace to find effective treatments for the disease it causes, COVID-19. That work, in which physicists and chemists are deeply involved, has made significant strides in the pastContinue reading “Cats, Llamas, Coronavirus Therapies…”
