Although many archaea have tough outer cell walls, these walls contain different kinds of amino acids and sugars than those found in bacteria. Archaeal cell membranes also are chemically distinct from bacterial membranes with differing lipid structures and chemical links. This means that drug... Read More
Viruses can act as miniature couriers. When they infect, they may inadvertently take up a bit of their host’s DNA and have it copied into their progeny. When the offspring viruses move on to infect new cells, they may insert this bit of accidentally pilfered DNA into the new hosts’ genome. This ... Read More
Tracey McDole, a PhD student in the lab of Dr. Forest Rohwer, San Diego State University, has authored a post on Small Things Considered that looks at recent research published in PNAS that questions the physical limits to cell behavior.
"The word marginal means to be at the outer or lower l... Read More
Some archaea look like little rods or tiny balls, and some even get around like bacteria, using long hair- or whip-like appendages called flagella that stick out of their cell walls and act like a microscopic outboard motor to get them where they are going.... Read More
The most clearly plant-like algae, this species gets its namesake hue from high levels of chlorophyll.
Their cell walls are made up of cellulose, the same material that makes up the cell walls in larger, multicellular plants. Like plants, they store the food they make through photosyn... Read More
In the past 100 years we’ve learned that each one of us has unique fingerprints, and unique DNA sequences. Now through the Human Microbiome Project, we’re learning that every one of us has a unique and identifiable bacterial community not only inside of us, but also growing on our skin as well....

Here is a transcript of TWiM episode #49, "Grape-like clusters". Thanks to Frank Shinneman for transcription.
Dear Vincent and Dickson,
Listening to TWiP on cyclosporiasis. Because I am all too aware of the possible contamination of many crops as a former public health nurse who worked in epidemiology for my state (Florida), I always wash my fruits and v... Read More
New recommendation encourages physicians to prescribe _antibacterials_ instead of antibiotics for bacterial infections. This recommendation is based on compelling evidence that the word "antibiotic" confuses almost everyone, including some doctors. The confusion leads to strong patient demands... 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
A new data resource for measuring the accuracy of metagenomic binning methods, created by in vitro-simulation of a metagenomic community, can be used to complement previous in silico benchmark studies. In constructing a synthetic community and sequencing its metagenome, researchers from the Univ... Read More
"The emergence of the influenza A(H1N1)2009 virus provided a major challenge to health services around the world. However, vaccination rates for the public and for healthcare workers (HCWs) have remained low. We performed a study to review the reasons put forward by HCWs to refuse immunisation w... Read More
