SignificanceWe found exitrons (exonic introns) in four Odorant receptor (Or) genes of Drosophila. Exitrons are sequences that can be spliced from within a protein-coding exon, thereby altering the encoded protein. We are unaware of previous reports of exitrons in Drosophila. Removal of the exitron from the pheromone receptor gene Or88a creates a non-coding transcript.

SignificanceWe live within the Atmospheric Boundary Layer (ABL), where air flow feels the friction of the planet’s surface, producing turbulence. When ABLs encounter changes in roughness—from sea to land, or rural to city—a near-surface region with distinct turbulence characteristics develops. The structure within influences transport of heat and dust; yet, data in this region are sparse, with existing models unable to capture important behaviors.

SignificanceComputational protein structure prediction has been significantly improved by the application of coevolution information derived from multiple sequence alignment (MSA) and deep learning. Although very powerful, these methods do not perform well on small-sized protein families, flexible regions such as highly variable antibody Complementarity-determining region (CDR) regions, and single mutation effects.
