Microbes can tailor transcriptional responses to diverse environmental challenges despite having streamlined genomes and a limited number of regulators. We present data‐driven models that capture the dynamic interplay of the environment and genome‐encoded regulatory programs of two types of prok... Read More
Head of the US National Institutes of Health Francis Collins was asked some tough questions by a House of Representatives subcommittee examining the new National Center for Advancing Translational Sciences, NCATS. The goal of the new center, opened in 2012, is to reduce the amount of time needed... Read More
Three years ago today, on 13 January 2011, the last case of poliomyelitis was reported in India. This achievement represents a remarkable turnaround for a country where control of the disease had for years been extremely difficult. As recently as 2009 there were 741 confirmed cases of polio caus... Read More
The American Academy of Microbiology has released its newest report on the human microbiome. Based on the deliberations of some of the leading experts, the report answers common questions people have about this new field of science. While there is still much to be learned, this report presents t... Read More

Because all animal viruses initiate infection by binding to a receptor on the cell surface, this step has long been considered a prime target for antiviral therapy. Unfortunately, drugs that block virus attachment to cells have never shown much promise. Another approach, which is to ablate the r... Read More
The spring semester has begun at Columbia University, which means that it is time to teach my virology course. The fourth annual installment of my virology course, Biology W3310, has begun. This course, which I taught for the first time in 2009, is intended for advanced undergraduates and conven... Read More

In this blog post, I describe a simple "colony transformation" experiment I have done with my freshman students, illustrating transformation, antibiotic resistance, and GFP. The visual aspects help drive home the points effectivel. Read More
Greetings Vincent and Dick,
Hooray for finally mentioning G. pulchrum in episode 62, my most favorite parasite and one worthy of further discussion. As a diagnostic veterinary pathologist, I encounter this spirurid in approximately... Read More
Earlier this month the European Molecular Biology Laboratory (EMBL) published the DNA sequence of the genome of HeLa cells, the cell line that is widely used for research in virology, cell biology, and many other areas. This cell line was produced from a tumor taken from Henrietta Lacks in 1951.... Read More

When antibiotics first started being used in the 1940's they were considered a "miracle drug". It seemed that bacterial infections would no longer be a problem for the world. However, recently, one gene is making it seem as though the end of antibiotics is at hand. This gene is New Delhi metallo... Read More
Deans of public health schools in the United States have sent a letter to President Obama, in which they criticize the use of a vaccination campaign by the Central Intelligence Agency in Pakistan to hunt for Osama bin Laden. I wonder if he will reply. Read More
Neisseria meningitidis may cause septicemia (bacteria in the blood) and meningitis (infection of the membrane surrounding the brain), but the bacterium colonizes the nasopharynx in 10-20% of the human population without causing disease. Although understanding how the bacterium changes from a com... Read More
