Fifth-Column Fascists…

Topics: Civics, Civil Rights, Existentialism, Fascism, Human Rights, Propaganda Note: I will be attending the funeral of my brother-in-law. I will take a blog break to mourn. [A] fifth column, clandestine group or faction of subversive agents who attempt to undermine a nation’s solidarity by any means at their disposal. The term is conventionally creditedContinue reading “Fifth-Column Fascists…”

RNA and Covid-19…

Topics: Biology, Biotechnology, COVID-19, Diversity in Science, NIST, Research, Women in Science Scientists track and monitor the circulation of SARS-CoV-2, the virus that causes COVID-19, using methods based on a laboratory technique called polymerase chain reaction (PCR). Also used as the “gold standard” test to diagnose COVID-19 in individuals, PCR amplifies pieces of DNA byContinue reading “RNA and Covid-19…”

Aharonov-Bohm Effect…

Topics: General Relativity, Gravity, Modern Physics, Quantum Mechanics The idea that particles can feel the influence of potentials even without being exposed to a force field may seem counterintuitive, but it has long been accepted in physics thanks to experimental demonstrations involving electromagnetic interactions. Now physicists in the US have shown that this so-called Aharonov-BohmContinue reading “Aharonov-Bohm Effect…”

DUNE…

Topics: Fermilab, High Energy Physics, Modern Physics, Neutrinos, Particle Physics Solving big mysteries The Deep Underground Neutrino Experiment is an international flagship experiment to unlock the mysteries of neutrinos. DUNE will be installed in the Long-Baseline Neutrino Facility, under construction in the United States. DUNE scientists will paint a clearer picture of the universe and how itContinue reading “DUNE…”

Cosmic Existentialism…

Topics: Astronomy, Astrophysics, Black Holes, Cosmology, Einstein, General Relativity “Small” black holes are estimated to make up 1% of the universe’s matter. Scientists have estimated the number of “small” black holes in the universe. And no surprise: It’s a lot. This number might seem impossible to calculate; after all, spotting black holes is not exactly the simplestContinue reading “Cosmic Existentialism…”

Spitballing…

Topics: Civics, Civil Rights, Existentialism, Fascism, Human Rights Note: title inspired by a tweet from Congressman Adam Schiff. In Congress, July 4, 1776 The unanimous Declaration of the thirteen united States of America, When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them withContinue reading “Spitballing…”

Dyson Sphere Feedback…

Topics: Astronomy, Astrophysics, Dyson Sphere, SETI Although the so-called Dysonian SETI has been much in the air in recent times, its origins date back to the birth of SETI itself. It was in 1960 – the same year that Frank Drake used the National Radio Astronomy Observatory in Green Bank, West Virginia to study EpsilonContinue reading “Dyson Sphere Feedback…”

Exomoon Two…

Topics: Astronomy, Astrophysics, Exomoon, Exoplanets And then there were two—maybe. Astronomers say they have found a second plausible candidate for a moon beyond our solar system, an exomoon, orbiting a world nearly 6,000 light-years from Earth. Called Kepler-1708 b-i, the moon appears to be a gas-dominated object, slightly smaller than Neptune, orbiting a Jupiter-sized planet around a sunlikeContinue reading “Exomoon Two…”

Moments and Metaphors…

Topics: Astronomy, Astrophysics, Comets, Philosophy, Science Fiction On a recent morning, in Lower Manhattan, 20 scientists, including me, gathered for a private screening of the new film Don’t Look Up, followed by lunch with the film’s director, Adam McKay. The film’s plot is simple. An astronomy graduate student, Kate Dibiasky (Jennifer Lawrence), and her professor,Continue reading “Moments and Metaphors…”

Strain and Flow…

Topics: Applied Physics, Condensed Matter Physics, Electrical Engineering Using a technique known as strain engineering, researchers in the US and Germany have constructed an “excitonic wire” – a one-dimensional channel through which electron-hole pairs (excitons) can flow in a two-dimensional semiconductor like water through a pipe. The work could aid the development of a newContinue reading “Strain and Flow…”
