In order to feed the growing global population that is expected to reach 9 billion by 2050, agricultural yields will need to increase by 70-100%. However, increasing this yield using current methods is not a viable option. Not only is it environmentally damaging, it is also not economically feas... Read More

In this blog post, I show how students in my freshman "introduction to cell and molecular biology" course used "creativity"-based approaches to better understand concepts in the course---as they prepare for their upcoming final exam. I believe that this kind of approach truly helps with student... Read More
Did you see this paper in PLoS Computational Biology? It's mind-blowing. U. Maryland researchers found evidence for Acinetobacter and Pseudomonas nucleic acid integrated into human chromosomes and mitochondria, po... Read More
Emergence and dissemination of antibiotic resistance plasmids are major concern for hospital care system and
increases the cost and decreases effectiveness of available antibiotics used in treatment of hospitalized patients.
In this study two Pseudomonas aeruginosa, two Escherichia coli, and a... Read More
This episode: Bacteria could reduce mercury's toxicity in their environment!

Methanotrophs (bacteria that use methane for their carbon and energy) secrete siderophore-like compounds that are usually used to chelate copper and make it more bioavailable, but ... Read More
Archaeans dine on a variety of substances for energy, including hydrogen gas, carbon dioxide and sulfur. One type of salt-loving archaean uses sunlight to make energy, but not the way plants do it. This archaean has a light-harvesting pigment in the membrane su... Read More
Poliovirus has been found in sewage in Israel. The virus detected is not vaccine-derived poliovirus; it is wild-type 1 poliovirus, the strain that occurs naturally in the wild and which the World Health Organization is trying very hard to eradicate from the planet. Read More
I just finished listening to TWiV 152, in which you spent quite some time discussing the death of Steve Jobs the past week. Though this mention is certainly well-deserved, I thought it was an oversight not to make any mention of the outstanding immunol... Read More
An outbreak of hepatitis A virus (HAV) infections in eight US states has been attributed to consumption of Townsend Farms Organic Anti-Oxidant Blend frozen berry and pomegranate mix purchased from Costco markets. Since March 2013, 118 individuals have acquired the infection and 80% report having... Read More
Scientists have developed a strain of the Middle East respiratory syndrome coronavirus (MERS-CoV) that could be used as a vaccine against the disease, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology. The mutant MERS virus, rM... Read More
In this blog entry, I discuss the perennial problem for educators: helping students find study strategies that help them reach their educational goals. I have found that student-generated study material is most helpful...and is sometimes quite artistic! Read More
This episode: Gut bacteria may convert cortisol into important human hormones!
(6 MB, 6.5 minutes)
Note: Episode 144 is now available too. Sorry about that. Not sure what went wrong there, but it is regrettable.
A minor player in the gut, Clostridium scindens,... Read More
In this blog entry, I discuss a talk I attended at ASMCUE about "Citizen Science" and how some of my own work appeared in that talk! It is a vital that we scientists explain not just what we do, but why it is so fascinating to us...by involving the public! Read More
Bacteria can be found virtually everywhere. They are in the air, the soil, and water, and in and on plants and animals, including us. A single teaspoon of topsoil contains about a billion bacterial cells (and about 120,000 fungal cells and some 25,000 algal cells). The human mouth is home to ... Read More
The American Academy of Microbiology has released its newest report about the West Nile virus. Questions answered include: Can West Nile virus outbreaks be prevented? Why do some people get West Nile fever? How did the West Nile virus spread across the country so quickly?
The free report can ... Read More
If you teach students about viruses and bacteria, recent episodes of The Walking Dead have been using the term "antibiotic" to stand for antivirals. Since students are probably watching the show, it might be a good time to highlight the mistake. I summarized the issues at the associated URL (ht... Read More
When virologists Fouchier and Kawaoka were isolating avian influenza H5N1 viruses that could transmit among ferrets by aerosol, there was consternation from some quarters that such viruses might escape from the laboratory and cause a pandemic in humans. Part of the fear came from the fact that t... Read More
