A recent paper published in PLoS One describes a systems biology approach that models how Staphylococcus aureus develops methicillin resistance.
The obtained results by our integrated approach show that the model describes correctly the whole phenomenon of the methicillin resistance and is ab... Read More
Group B Streptococcus (GBS), a bacterial pathogen that causes sepsis and meningitis in newborn infants, is able to shut down immune cell function in order to promote its own survival, according to researchers at the University of California, San Diego School of Medicine and the Skaggs School of ...

A new survey published by the Pew Research Center for the People & the Press and the American Association for the Advancement of Science checks the pulse of how scientists and the public view the field of science. For example:
17% of the public thinks that U.S. scientific achievements rate a... Read More
"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
The CDC has released new guidelines for moms concerned abouth whether they should breast feed their children if they have H1N1 or Swine Flu.

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
While this instructional video is good, the narrator's "dracula" accent is downright silly. Click source to learn how to successfully streak a plate and to watch out for common problems associated with the technique. Read More
23andme, "the world's trusted source of personal genetic information", has produced a great animation series about genes and genetics. The films will be aired during Gene Screen, a night of film on health and genetics in Washington, D.C. on July 16. Watch an animated guide to your genes, SNPs, p... Read More
A paper published in PubMed that appeared in the July 1967 edition of Applied Microbiology reports that men with beards who work in microbiology labs may be a public health hazard. The authors conclude that although lab personnel who wash their beards reduced the amount of virus or toxin, a suff... Read More
The science of metagenomics has uncovered that viruses are the most abundant and genetically diverse organisms on earth. In an article published in Microbiology Today, Peter Simmons from the Centre for Infectious Diseases, University of Edinburgh, discusses how discoveries of new viruses are pro... Read More
This article looks at key challenges when using agricultural waste as a sustainable source for biofuels to meet worldwide energy needs. Subjects include dealing with diverse cellulosic sugars and finding ways to recycle carbon dioxide back into useful biomass.
Why plants such as sugar cane and ... Read More

Vincent Racaniello from This Week in Virology has a great post on his site about what happens to the immune system during the initial infection of an influenza virus:
During the earliest stages of a virus infection, cytokines are produced when innate immune defenses are activated. The rapid ... Read More
While estimates of the number of genes in the human genome is said to be around 20,000, new research estimates that if you take into account our microbiota there may be as many as 9 million genes in the human gut.
"A new concept is to consider human as a super-organism containing those microb... Read More
