"Self-assembling and self-organizing systems are the Holy Grails of nanotechnology, but nature has been producing such systems for millions of years. A team of scientists has taken a unique look at how thousands of bacterial membrane proteins are able to assemble into clusters that direct cell m... Read More
New research from PLoS on novel hantavirus genomes in moles challenges the current thinking that rodents are the originating hosts for the disease.
From the abstract:
The discovery of genetically distinct hantaviruses in shrews (Order Soricomorpha, Family Soricidae) from widely separated ... Read More
New research on the prevalence of "sin nombre" hantavirus in deer mice authored by Laurie J. Dizney and Luis A. Ruedas from Portland State University and published in the CDC's Emerging Infectious Diseases Journal suggests a diversity of animal species helps defend against the emergence of patho... Read More

This is an interesting documentary about superbugs, such as MRSA, antibiotic resistance and Russia's research into bacteriophage (viruses that attack bacteria) as a treatment for people with bacterial-related diseases. This video was produced in 1997 by the BBC, but despite the air date, ther... Read More
Bioinformatics, the application of computer analysis to molecular biology, is a fundamental corollary to biodefense research. As we face new security threats involving pathogens and infectious disease, bioinformatics databases must be improved and a plan must be made for integrating biodefense r... Read More
Virginia Campbell,MD, host of the Brain Science Podcast, has published a very interesting interview with Dr. Paul Offit, author of the book Autism’s False Prophets. In the interview, Campbell and Offit explore "the scientific evidence that vaccines DO NOT cause autism, but also examine why the c... Read More
