One of the basic requirements of evolution is variation in a population upon which selection can act. One of the sources of variation is mutation in DNA. These changes may or may not be reflected in the ensuing amino acid sequence of a protein. This exercise explores the additive effects of m... Read More
The most clearly plant-like algae, this species gets its namesake hue from high levels of chlorophyll.
Their cell walls are made up of cellulose, the same material that makes up the cell walls in larger, multicellular plants. Like plants, they store the food they make through photosyn... Read More
This parasite interacts with many host proteins and modifies the expression of many more genes creating an interactome with almost 3000 links. In addition it exchanges substrates and metabolites with the host, modifying many biochemical parameters. T.Gondii disrupts multiple signalling network... Read More
Host: Jeff Fox with special guest, Warren C. Ruder.
Warren C. Ruder of Virginia Polytechnic Institute and State University (Virginia Tech) in Blacksburg, Virginia talks with Jeff Fox about efforts to develop an electronic model system that incorporates a robot for a host and two sligh... Read More
A permissive vaccine prevents disease in the immunized host, but does not block virus infection. Would a permissive vaccine lead to the emergence of more virulent viruses?
This hypothesis is based on the notion that viruses which kill their hosts too quickly are not efficiently transmitted, a... Read More
This is a database of Herpes simplex (HSV-1) host/viral interactions hosted at WikiGenes. It provides a global snapshot of what the virus does in different compartments at all stages of the viral life-cycle from entry to exit. The database is interactive, and any researcher can edit the page or ... Read More
Chimpanzees from African sanctuaries carry drug-resistant, human-associated strains of the bacteria Staphlyococcus aureus, a pathogen that the infected chimpanzees could spread to endangered wild ape populations if they were reintroduced to their natural habitat, a new study shows.
The study ... Read More
Here is a follow-up to last week’s article that described a case of variant Creutzfeldt-Jacob disease in a Texas resident caused by ingestion of BSE-contaminated beef 14 years ago.
A 59 year old male patient was admitted to the trauma unit in Lancaster, PA with a self-inflicted gunshot wound ... Read More

Both Nature and the New York Times have weighed in on the resumption of influenza H5N1 research. In an editorial from 23 January 2013, Nature opines that “Experiments that make deadly pathogens more dangerous demand the utmost scrutiny”. They call for a quantitative risk-benefit analysis of H5N1... Read More
Hyperthermophiles are microorganisms that can live in extremely hot conditions. Instead of photosynthesis, these organisms perform chemosynthesis to produce energy. Click "source" above to watch the Learning Channel's "It Came From Outer Space: Hyperthermophiles". Read More
