Elio Schaechter of Small Things Considered defines the term "ontology" and why its destined to become part of every biologist’s vocabulary. Read More
A video from the DOE JGI '09 User Meeting on March 27, 2009 featuring Craig Venter's keynote talk "Reading and Writing the Genetic Code."
GEMINA is a web-based system to identify infectious pathogens and their representative genomic sequences through selection of associated epidemiology metadata. Gemina supports the development of DNA signature-based assays for the detection of pathogens or sets of pathogen through the Insignia Si... Read More
A new paper publish in PLoS One concludes that programs that optimize adherence to highly-active antiretroviral therapy (HAART) through direct observation in pregnancy have the potential to diminish mother-to-child HIV transmission in a highly cost-effective manner. Read More
It has always been assumed that plant viruses cannot infect animals, and vice versa, but plant viruses are known to be abundant in human faeces.
Now Didier Raoult at the University of the Mediterranean in Marseille, France, and his team think a pepper virus is making people sick, too.

Deep sequencing – which identified a viral contaminant of the rotavirus vaccine Rotarix - could have revealed the presence of simian virus 40 (SV40) in the poliovirus vaccine, had the technique been available in the 1950s. Exposure of over 100 million Americans to SV40, and many more worldwide, ... Read More
Tracing the origin of an outbreak is a critical clue in curing a disease. But how can scientists track the beginnings of malaria, a disease that has been around for millions of years? Watch researcher Read More
Welkin Johnson, Assistant Professor of Microbiology and Molecular Genetics at Harvard Medical School and an Associate Blogger for Small Things Considered, ponders the "fossil record" of viruses:
"As a scientist fascinated with the evolutionary interplay between viruses and their hosts, I admi... Read More
In regard to your question as to cases of known alteration of host behavior by virus that increases the rate of contact among hosts (Twiv 70), the most dramatic example is given by rabies. This extraordinary virus can convert a neurologically and behaviorally... Read More
On episode #77 of the podcast This Week in Virology, Vincent, Alan, and Rich revisit circovirus contamination of Rotarix, then discuss poxvirus-like replication of mimivirus in the cell cytoplasm, a... Read More
The contamination of the rotavirus vaccine Rotarix with porcine circovirus 1 DNA was revealed by deep sequencing. The same technique was also used to demonstrate that oral poliovirus vaccine does not contain viruses that can cause poliomyelitis. Read More
Nanne Nanninga, Emeritus Professor of Molecular Cytology, Swammerdam Institute for Life Sciences, University of Amsterdam, The Netherlands, authors a guest post on Small Things Considered that questions whether van Leeuwenhoek actually observed yeast cells in 1680.

The first video in brief set of three lectures by Joseph DeRisi gives a very general overview of malaria, the disease and Plasmodium falciparum, the causative agent of the most deadly form. Basic research as well as drug development efforts will also be covered in parts two and three of this ser... Read More
