Diversity or Dystopia…

Topics: Civics, Civil Rights, Existentialism, Fascism, Human Rights, Star Trek “It is no longer a choice, my friends, between violence and nonviolence. It is either nonviolence or nonexistence. And the alternative to disarmament, the alternative to a greater suspension of nuclear tests, the alternative to strengthening the United Nations and thereby disarming the whole world,Continue reading “Diversity or Dystopia…”

Studying UAPs…

Topics: Astrophysics, NASA, SETI I was startled, to say the least, that this story appears in Scientific American, and that NASA and theoretical astrophysicist Avi Loeb is interested in it. The nut job “giggle factor” has given way to curiosity about things humans cannot explain, and that bothers us as a species. My concern isContinue reading “Studying UAPs…”

Nucleocapsid Rhapsody…

Topics: Biology, COVID-19, Research Abstract SARS-CoV-2 nucleocapsid protein (N) induces strong antibody (Ab) and T cell responses. Although considered to be localized in the cytosol, we readily detect N on the surface of live cells. N released by SARS-CoV-2–infected cells or N-expressing transfected cells binds to neighboring cells by electrostatic high-affinity binding to heparan sulfateContinue reading “Nucleocapsid Rhapsody…”

Cooling Centers…

Topics: Climate Change, Environment, Existentialism The heat index in Jefferson County reached 105 degrees by noon Monday — and it’s only getting hotter. More than 50 million Americans face scorching temperatures as a heatwave spreads over most of the country this week. Louisville could see heat indices as high as 115 degrees, putting many residents at risk of heatContinue reading “Cooling Centers…”

ARDP…

Topics: Applied Physics, Alternate Energy, Climate Change, Nuclear Power According to the US Energy Information Administration, the US uses a mixture of 60.8% fossil fuel sources to generate 2,504 billion kilowatt hours of energy. Our nuclear expenditure is a paltry 18.9%. The totality of renewable sources (wind, hydropower, solar, biomass, and geothermal) is a littleContinue reading “ARDP…”

Occam’s on Steroids…

Topics: Civics, Civil Rights, Existentialism, Fascism, Politics Originally from the entry: Apathy, Crisis, and Zappa (another blog I posted to before WordPress). So what exactly is a constitutional crisis? We should be clear about what does — and, more importantly, does not — merit this description. It’s possible to have a major political crisis evenContinue reading “Occam’s on Steroids…”

Quipu…

Topics: Lasers, Modern Physics, Quantum Computer, Quantum Mechanics Physicists have devised a mind-bending error-correction technique that could dramatically boost the performance of quantum computers. When the ancient Incas wanted to archive tax and census records, they used a device made up of a number of strings called a quipu, which encoded the data in knots. Fast-forwardContinue reading “Quipu…”

DUNE Detector…

Topics: Applied Physics, Modern Physics, Particle Physics, Theoretical Physics The Deep Underground Neutrino Experiment (DUNE) will be the world’s largest cryogenic particle detector. Its aim is to study the most elusive of particles: neutrinos. Teams from around the world are developing and constructing detector components that they will ship to the Sanford Underground Research Facility,Continue reading “DUNE Detector…”

4D Beetles…

Topics: 3D Printing, Additive Manufacturing, Biomimetics Researchers in the Netherlands have produced models of a beetle that changes color and a scallop shell that opens and closes in response to changing humidity in the surrounding air. Inspired by iridescent structures in nature, Jeroen Sol and colleagues at the Eindhoven University of Technology showed that they could integrateContinue reading “4D Beetles…”

Counting in Counties…

Topics: Civics, Civil Rights, Civilization, Climate Change, Existentialism, Politics Reality literally bites. During the COVID-19 pandemic, the link between politics and health became glaringly obvious. Democrat-leaning “blue” states were more likely to enact mask requirements and vaccine and social distancing mandates. Republican-leaning “red” states were much more resistant to health measures. The consequences of thoseContinue reading “Counting in Counties…”
