A nice thought piece by Ford Doolittle in PLoS Genetics. We run our first year students though this each year, so it is nice to think that some of them might find and be influenced by this article next year. … Continue reading
Cyanobacteria in the oceans are among the world’s most important oxygen producers and carbon dioxide consumers. Synechocystis is a spherical single-celled cyanobacterium that measures about three thousandths of a millimetre across. Because Synechocystis needs sunlight to produce energy, it is … Continue reading
A half century of structural studies have shown the design principles controlling self-assembly of viral proteins into icosahedral virus capsids. A large repertoire of virus structures, mainly determined using X-ray crystallography and cryo-electron microscopy, are now conveniently available and carefully … Continue reading
A new paper in eLife describes the genetic diversity and novel genome structures of RNA viruses from arthopods, shedding new light on the ancestry and evolutionary history of plant and animal RNA viruses. Unprecedented genomic diversity of RNA viruses … Continue reading
A new review in Annual Review of Microbiology gives an excellent introduction to viroids. Continue reading
There are two types of biologist – those who think that prokaryotes exist and those who don’t. Continue reading
This short review is an easily accessible introduction to the the three domains of life – Eukarya, Bacteria, and Archaea. Continue reading
The ongoing dance between a virus and its host shapes how the virus evolves. Continue reading
L-forms are bacterial variants that lack a cell wall and divide by a variety of processes. Continue reading
