Pairwise distance demarcation of species in the family Coronaviridae. a, Diagonal matrix of PPDs of 2,505 viruses clustered according to 49 coronavirus species, 39 established and 10 pending or tentative, and ordered from the most to least populous species, from left to right; green and white, PPDs smaller and larger than the inter-species threshold, respectively. Areas of the green squares along the diagonal are proportional to the virus sampling of the respective species, and virus prototypes of the five most sampled species are specified to the left; asterisks indicate species that include viruses whose intra-species PPDs crossed the inter-species threshold (threshold 'violators'). b, Maximal intra-species PPDs (x axis, linear scale) plotted against virus sampling (y axis, log scale) for 49 species (green dots) of the Coronaviridae. Indicated are the acronyms of virus prototypes of the seven most sampled species. Green and blue plot sections represent intra-species and intra-subgenera PPD ranges. The vertical black line indicates the inter-species threshold. c, Shown are the PDs of non-identical residues (y axis) for four viruses representing three major phylogenetic lineages (clades) of the species Severe acute respiratorysyndrome-related coronavirus (panel b) and all pairs of the 256 viruses of this species ('all pairs').

Data from: Molecular square dancing in CO-CO collisions
<p>Knowledge of rotational energy transfer (RET) involving carbon monoxide (CO) molecules is crucial for the interpretation of astrophysical data. As of now, our nearly perfect understanding of atom-molecule scattering shows that RET usually occurs by only a simple "bump" between partners. To advance molecular dynamics to the next step in complexity, we studied molecule-molecule scattering in great detail for collision between two CO molecules. Using advanced imaging methods and quasi-classical and fully quantum theory, we found that a synchronous movement can occur during CO-CO collisions, whereby a bump is followed by a move similar to a "do-si-do" in square dancing. This resulted in little angular deflection but high RET to both partners, a very unusual combination. The associated conditions suggest that this process can occur in other molecule-molecule systems.</p>

"When Cotton Was King" Display at Liberty Square
Text from the exhibit: "WHEN COTTON WAS KING In 1860, the South grew an astonishing 2.28 billion pounds of cotton. Cotton exports that same year generated $191,800,000. This figure represented 57% of the nation's total export revenue. Southern cotton planters felt economically powerful and politically confident that the national government in Washington could not afford to alienate them by destabilizing the institution of slavery."

Data underpinning "Noncoplanar magnetic order in classical square-kagome antiferromagnets"
<p>Motivated by the recent synthesis of a number of Mott insulating square-kagome materials, we explore the rich phenomenology of frustrated magnetism induced by this lattice geometry, also referred to as the squagome or shuriken lattice. On the classical level, square-kagome antiferromagnets are found to exhibit extensive degeneracies, order-by-disorder, and non-coplanar ordering tendencies, which we discuss for an elementary, classical Heisenberg model with nearest-neighbor and cross-plaquette interactions. Having in mind that upon introducing quantum fluctuations non-coplanar order can melt into chiral quantum spin liquids, we provide detailed information on the multitude of non-coplanar orders, including some which break rotational symmetry (possibly leading to nematic quantum orders), as well as a number of (incommensurate) spin spiral phases. Using extensive numerical simulations, we also discuss the thermodynamic signatures of these phases, which often show multi-step thermal ordering. Our comprehensive discussion of the classical square-kagome Heisenberg model, often drawing comparisons to the conventional kagome antiferromagnet, sets the stage for future explorations of quantum analogs of the various phases, either conceptually such as in quantum spin-1/2 generalizations of our model or experimentally such as in the Cu-based candidate materials.</p>

Square Tower House, Mesa Verde Colorado
Located in today's southern Colorado, Ancestral Puebloans moved into the Mesa Verde area about 550 CE. Square Tower Dwellings - Mesa Verde, ColoradoThe Ancestral Puebloans (village dwellers) were at one time mistakenly called Anasazi, a Navajo word meaning enemy ancestors. One of popular stops on the Mesa Top Loop Road is this multi story cliff dwelling called Square Tower House. The structure was well made of double-coursed stone walls, constructed around 1100 CE. A 200 year period, from 1100 to 1300, Mesa Verde reflected advanced building techniques and farming practices. The population of this area may have reached several thousand and created a fair amount of trash which ended up at the base of the cliff. What we know today of these early residents are found among the clues in this garbage heap. https://www.scenicusa.net/072406.html Created in RealityCapture by Capturing Reality from 914 images in 05h:48m:35s.
