Researchers find that surges in COVID-19 case numbers are associated with deletions in the SARS-CoV-2 genome in an antigenic site of the spike protein. Some of these mutations are present in vaccine breakthrough infections or reinfections.
New analyses find that divergent transcription, in which one promoter directs the expression of two adjacent genes oriented in opposite directions, is conserved across all domains of life.
While some experts speculate the variant could be partially responsible for India’s current surge in SARS-CoV-2 infections, information about the effects of its mutations is only beginning to emerge.
In a trio of studies, researchers follow up on a 40-year-old finding that certain bacteriophages replace adenine with so-called diaminopurine, perhaps to avoid host degradation.
A study of human populations around the world detects differing rates of horizontal gene transfer in the microbiome depending on what kind of society those people live in.
Martha Nelson of the National Institute of Allergy and Infectious Diseases talks about the need to balance data sharing and patient privacy concerns when tracking the spread of variants.
Scientists across the world are closely tracking the spread of mutations in the coronavirus and investigating whether they could render current vaccines less effective.
Over centuries of cultivating Saccharomyces cerevisiae to make dough, bakers have put selective pressure on the species, causing it to diverge into two distinct groups, according to the authors.
