We typically spend close to 90 percent of our time inside - at school, work and home. While outdoor air quality is very important, so too is the quality of the air we breathe at home and the office. Yet most of us know very little about the condition of our indoor climate. The chemicals ... Read More
Merry Youle of Small Things Considered has a new post about the history of American chestnut blight and the scientific efforts to restock North America with these stately giants through the introduction of biological control agents or with more traditional plant breeding techniques.

A serological test is highly accurate at finding tuberculosis infection in elephants, and can determine such infection years before culture, according to a study in the August Clinical and Vaccine Immunology (click source to download the .pdf of the journal article). The issue is critical not on... Read More
Great HAI work! I'm not through it yet. I want to question, though, whether fomites are really important in influenza transmission. I don't think so.

Vincent, Dickson, and Daniel present a new case study, and discuss the effect of chronic malaria infection on wild warbler life span and telomere degradation.
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
Hi Vincent and Dickson,
I was listening to the new episode of TWiP (episode 52) and one of your listeners wrote in asking about tree parasites. While plant parasite is not my main field of research, I have written about one such pa... Read More
Current HIV treatments do not eradicate HIV from host cells but rather inhibit virus replication and delay the onset of AIDS. However, a new research published in BioMed Central's open access journal, AIDS Research & Therapy describes an innovative approach to eliminate HIV in host by targeted ... Read More
Jay Keasling, CEO of the Joint BioEnergy Institute, delivers the opening keynote on March 24, 2010 at the 5th Annual DOE JGI User Meeting. Read More
Maryn McKenna summarizes what we know about the murder of six people working as polio vaccinators who were targeted in three separate coordinated attacks in Pakistan. This comes in the wake of the CIA ruse in 2011 who used an immunization campaign to find Osama Bin Laden. Read More
Professors, you've discussed this idea before, but I thought you'd enjoy this nice summary from Nature:
In 2011, for the first time, countries across the WHO regions of Africa, Americas, Eastern Mediterranean, Europe and the Western Pacific are taking part in simultaneous immunization weeks. This unprecedented collaborated effort between the regions is building public and professional awareness of... Read More
Few technical breakthroughs have changed the face of their field like the Polymerase Chain Reaction (PCR). Gene cloning, sequencing of complex genomes, DNA fingerprinting and DNA-based diagnostics are just some of the techniques that were either inefficient, crude or plain impossible before PCR....

The lethality of avian influenza H5N1 infections in humans has been a matter of extensive debate. The >50% case fatality rate established by WHO is high, but the lethality of the virus might be lower if there are many infections accompanied by mild or no disease. One way to answer this question ... Read More
This recent talk at TED by Bonnie Bassler on bacterial communication (aka quorum sensing) was a viral hit among the science geeks on Twitter. It is a very educational and well thought out presentation that is great for personal viewing or showing in the classroom. It's a must watch! Read More
Learn about PCR and qPCR from world experts on the subject in this 6-part series brought to you over the web. Topics include the history of PCR from Carl Wittwer, an inventor of the LightCycler, discussions on the optimization and chemistry for PCR, and applications including methylation PCR and... Read More
