The new, more transmissible variant of SARS-CoV-2 found in England is just one of many variations of the virus being detected around the world. Elisabeth Mahase looks at what we know so far 
Beyond the jab: The availability of drugs for COVID-19
TLDR
How prescribing has changed during the coronavirus pandemic is looked at by Mark Greener at the Royal College of Surgeons in London.
The Up state of the SARS-COV-2 Spike homotrimer favors an increased virulence for new variants
TLDR
Analysis of possible molecular mechanisms responsible for the increased transmissibility and the increased rate of hospitalizations related to variants of SARS-CoV-2 showed that the increased virulence is more likely to be due to the improved stability to the S trimer in the opened state than due to alterations in the complexation RBD-ACE2.
How will emerging SARS-CoV-2 variants impact herd immunity?
TLDR
The impact of these emerging SARS-CoV-2 variants on herd immunity is discussed, whereby higher herd immunity threshold would be needed for arresting their circulation, whilst this in turn could be more difficult to achieve due to their stronger “resistance” to the current generation of vaccines.
SARS-CoV-2 genome surveillance in Mainz, Germany, reveals convergent origin of the N501Y spike mutation in a hospital setting
TLDR
It is suggested that the adaptive N501Y mutation, known to increase SARS-CoV-2 transmissibility, arose by convergent evolution around December in Mainz, Germany.

Genomic characterization of a novel SARS-CoV-2 lineage from Rio de Janeiro, Brazil
TLDR
A novel lineage of SARS-CoV-2, originated from B.1.28, distinguished by five single-nucleotide variants (SNVs), was identified and can be rapidly spread in the state of Rio de Janeiro, raising concerns about public health management and continuous need for genomic surveillance during the second wave of infections.
