TL;DR: A SARS-CoV-2 variant carrying the Spike protein amino acid change D614G has become the most prevalent form in the global pandemic, and it is found that the G614 variant grows to higher titer as pseudotyped virions.

TL;DR: In this paper, the authors compared the severity of the delta variant compared with the alpha variant by determining the relative risk of hospital attendance outcomes and found that outbreaks of the Delta variant in unvaccinated populations might lead to a greater burden on health-care services than the alpha variants.

TL;DR: In this article, the authors assessed RT-PCR swab-positivity in the REAL-time Assessment of Community Transmissibility (RACT) in many countries associated with the Delta variant.

TL;DR: Evidence shows that secondary contact can drive the evolution of phenotypic novelty, suggesting that pulses of secondary contact may repeatedly seed genetic novelty, which when coupled with ecological opportunity could promote rapid adaptive evolution in natural circumstances.

TL;DR: A new guppy reference genome assembly from a male is presented, using long-read PacBio single-molecule real-time sequencing and chromosome contact information and closes gaps and corrects mis-assemblies found in the short-read female-derived guppy genome.
