Phase transition and superconductivity of selenium under pressure.

Although a substantial amount of research has been conducted to unravel the structural configurations of selenium under pressure, the exquisite sensitivity of selenium's p-orbital electrons to this external force, leading to a plethora of structural variations, leaves several intermediary phases still shrouded in mystery. We, herein, systematically identify the structural and electronic transformations of selenium under high pressure up to 300 GPa, employing crystal structure prediction in conjunction with first-principles calculations. Our results for the transition sequence (321 → 2/ → 3̄ → 3̄) of selenium are in good agreement with experimental ones.

Sleep is a universally conserved behavior whose origin and evolutionary purpose are uncertain. Using phylogenomics, this article investigates the evolutionary foundations of sleep from a never before used perspective. More specifically, it identifies orthologs of human sleep-related genes in the Lokiarchaeota of the Asgard superphylum and examines their functional role.

The pseudogap phenomena have been a long-standing mystery of the cuprate high-temperature superconductors. The pseudogap in the electron-doped cuprates has been attributed to band folding due to antiferromagnetic (AFM) long-range order or short-range correlation. We performed an angle-resolved photoemission spectroscopy study of the electron-doped cuprates PrLaCeCuO showing spin-glass, disordered AFM behaviors, and superconductivity at low temperatures and, by measurements with fine momentum cuts, found that the gap opens on the unfolded Fermi surface rather than the AFM Brillouin zone boundary.

ConspectusPhotochemical reactions have always been the source of a great deal of mystery. While classified as a type of chemical reaction, no doubts are allowed that the general tenets of ground-state chemistry do not directly apply to photochemical reactions. For a typical chemical reaction, understanding the critical points of the ground-state potential (free) energy surface and embedding them in a thermodynamics framework is often enough to infer reaction yields or characteristic time scales.

It has long been known that a neural circuit situated in the spinal cord of mammals is independently capable of generating and modulating locomotor movements. Following its initial discovery over a century ago, a great deal of research has been focused on characterizing this neural circuit to determine how it is able to elicit movement. For much of the 20th century, difficulty in identifying individual component interneurons that comprised this neural circuit resulted in it being considered a powerful but mysterious "black box.
