"ABSTRACT "Here, we report on a computational comparison of the receptor-binding domains (RBDs) on the spike proteins of severe respiratory syndrome coronavirus‐2 (SARS-CoV-2) and SARS-CoV in free forms and as complexes with angiotensin-converting enzyme 2 (ACE2) as their receptor in humans. The impact of 42 mutations discovered so far on the structure and thermodynamics of …
16 Psyche – An M-type Asteroid
16 Psyche at Mag 9.9 last night in Aquaris © Dr. Kenneth M Beck Centre of this photo. 16 Psyche. An asteroid. From my balcony. Very quick. Not easy. Training. Getting better. More to come. 16 Psyche is one of the ten most massive asteroids in the main belt, and is the most massive M-type …
8 Flora – parent of the L chondrite family of meteorites
Flora's spectra indicates that its surface composition is a mixture of silicate, pyroxene, olivine with nickel-iron metal. Flora is considered a good candidate for being the parent body of the L-chondrite meteorites. Sci-fi fans may remember 8 Flora from The Green Slime (1968), where an orbital perturbation propels the asteroid Flora into a collision course with Earth. A …

Prof Dr Carl Sagan (R.I.P.)- 20DEC1996
24 years ago today in Seattle, Carl Sagan passed at Fred Hutch. So it goes. Remembered globally as the one man who could mesmerize a room with the ideas of hope and science; of “billions and billions of stars” generating “star-stuff” from which we all come. He is also remembered for his almost prophetic lectures …

15 Eumonia – S-type Astroid
15 Eumonia is a stony asteroid (S-type). It was magnitude ~9 last night. The star field of 15 Eumonia imaged and captured in 9 x 4" exposures last night. 15 Eunomia is a large asteroid in the inner asteroid belt. 15 Eunomia was discovered by Annibale de Gasparis in July 1851, and named after Eunomia, …

A “Verified” Understanding…
I will just post both of these certificates here. I really do appreciate science. I modeled the collapse of the Arctic Vortex in the years 2014-2017 using four, quad-core mini iMacs in a parallel cluster with Thunderbolt cabling; a very powerful, personal computer. I only used the publicly available Los Alamos Community ICE model, a …
“This Boeing-Backed Company Is Planning to Make Electric Airplanes”
https://www.popularmechanics.com/flight/news/a28540/boeing-backed-electric-plane-fly-2020s/ This story appears in the July 2018 issue. As experimental prototypes, electric airplanes have been around for decades. But the nagging question remains: Will they ever be commercially viable? Zunum Aero thinks so. It has 20 full-time employees and 20 contract workers spread across facilities in Kirkland (software operations) as well as Chicago and Indianapolis (electric manufacturing …
