ACE2 Gum and Covid…

Topics: Biology, Biotechnology, COVID-19, Research To advance a novel concept of debulking virus in the oral cavity, the primary site of viral replication, virus-trapping proteins CTB-ACE2 were expressed in chloroplasts and clinical-grade plant material was developed to meet FDA requirements. Chewing gum (2 g) containing plant cells expressed CTB-ACE2 up to 17.2 mg ACE2/g dry weightContinue reading “ACE2 Gum and Covid…”

Cobalt and Caveats

Topics: Battery, Chemistry, Climate Change, Environment, Politics KASULO, Democratic Republic of Congo — A man in a pinstripe suit with a red pocket square walked around the edge of a giant pit one April afternoon where hundreds of workers often toil in flip-flops, burrowing deep into the ground with shovels and pickaxes. His polished leatherContinue reading “Cobalt and Caveats”

Lithium and Caveats…

Topics: Alternate Energy, Battery, Biofuels, Chemistry, Climate Change, Environment California and the Biden administration are pushing incentives to make the United States a global leader in a market that’s beginning to boom: the production of lithium, the lightweight metal needed for the batteries of electric vehicles, and for the storage of renewable energy from powerContinue reading “Lithium and Caveats…”

Quantum AI…

Topics: Artificial Intelligence, Computer Science, Materials Science, Quantum Mechanics Quantum materials known as Mott insulators can “learn” to respond to external stimuli in a way that mimics animal behavior, say researchers at Rutgers University in the US. The discovery of behaviors such as habituation and sensitization in these non-living systems could lead to new algorithmsContinue reading “Quantum AI…”

Willful Ignorance…

Topics: Civics, Civil Rights, Climate Change, Existentialism, History, Human Rights There is a high price for willful ignorance. The above is Dr. Carl Sagan, an Astrophysicist, five years fresh off of the success of the original Cosmos series. He’s speaking about mitigating the effects of greenhouse gases, what is now referred to as global warmingContinue reading “Willful Ignorance…”

Kilonovas and Gold…

Topics: Astronomy, Astrophysics, Chemistry, Materials Science, Neutron Stars The amounts of heavy elements such as gold created when black holes merge with neutron stars have been calculated and compared with the amounts expected when pairs of neutron stars merge. The calculations were done by Hsin-Yu Chen and Salvatore Vitale at the Massachusetts Institute of Technology and Francois Foucart at the UniversityContinue reading “Kilonovas and Gold…”

Time…

Topics: Applied Physics, Education, Research, Thermodynamics Also note the Hyper Physics link on the Second Law of Thermodynamics, particularly “Time’s Arrow.” “The two most powerful warriors are patience and time,” Leo Tolstoy, War, and Peace The short answerWe can measure time intervals — the duration between two events — most accurately with atomic clocks. TheseContinue reading “Time…”

Your Brain on Covid…

Topics: Biology, COVID-19, DNA, Research Note: I have friends who thankfully survived infection now affected by this phenomenon. The article thus grabbed my attention. SARS-CoV-2 appears to travel widely across the cerebral cortex “Brain fog” is not a formal medical descriptor. But it aptly describes an inability to think clearly that can turn up inContinue reading “Your Brain on Covid…”

HETs…

Topics: Applied Physics, Computer Modeling, NASA, Space Exploration, Spaceflight Abstract Hall effect thrusters operating at power levels in excess of several hundreds of kilowatts have been identified as enabling technologies for applications such as lunar tugs, large satellite orbital transfer vehicles, and solar system exploration. These large thrusters introduce significant testing challenges due to theContinue reading “HETs…”

Kristallnacht…

Topics: Civics, Civil Rights, Democracy, Existentialism, Fascism, Human Rights Amid the GOP’s nationwide push against teaching about race and sexuality in schools, two members of the Spotsylvania County School Board in Virginia advocated for burning certain books, according to the Fredericksburg-based Free Lance-Star newspaper. This came as the school board directed staff to begin removing “sexually explicit” booksContinue reading “Kristallnacht…”
