Omicron Propagates 70 Times Faster than Delta in Bronchi: Study
Dan Robitzski | Dec 17, 2021
A preprint reports that the new SARS-CoV-2 variant multiplies faster in human bronchial tissue but slower in lung tissue than the Delta variant, potentially explaining how it’s spreading from person to person so quickly.
Artist’s renderings of SARS-CoV-2 float in front of a map showing the origins of various variants of the virus.
Omicron Is WHO’s Fifth Variant of Concern, Experts Urge Patience
Dan Robitzski | Nov 30, 2021
Preliminary data suggest that the newly dubbed Omicron variant may be more infectious than previous versions of the virus, but it will take time to obtain the reliable data needed to answer pressing questions about its biology.
Researchers use bacterial whole genome sequencing to compare the phylogenetic relationship between environmental and clinical samples.
Aquatic Bacteria Reveal a Common Genetic Link to a Deadly Human Pathogen

Study Links Flu to Increased Parkinson’s Risk a Decade Later
Dan Robitzski | Nov 19, 2021
Epidemiological research suggests that a flu diagnosis might be one factor in the eventual onset of the neurodegenerative disease, but experts say it doesn’t prove a causal relationship.

The Long Journey to Resolve the Origins of a Previous Pandemic
Martha Nelson | Sep 2, 2021
Dozens of researchers, including myself, worked for years to uncover that swine flu had leapt to humans from a pig in Mexico in 2009. We learned a lot about influenza evolution, pig farming, and outbreak risk along the way.

Dissecting the Unusual Biology of the SARS-CoV-2 Delta Variant
Katarina Zimmer | Aug 9, 2021
An ability to build up higher concentrations of viral particles in people’s airways and mutations that might boost its ability to infect human cells could be what gives the Delta variant its evolutionary edge.
