Microbial Pancakes

  Prepared by daughter. Not to scale. Species not yet identified. Delicious.  

Gut microbes and diabetes

It seems that every day we are discovering more about the role of microbes to our health. We really have to revise our definition of what a human (or any other animal or plant) is: we are not just a creatures of 10,000,000,000,000 cells containing the DNA we got from mother and father. We have [...]

Circumcision, preventing fraud, and icky toilets. You know you’re going to read this.

In no particular order or ranking, recent and not-so-recent articles from PLoS-1. The common thread (if any): I thought they were pretty cool in one way or another.   1. Men don’t tell the truth about their penis. No kidding? But this is somewhat more serious. It has been accepted for some time that male [...]

Not dead yet

  The Dead Body That Claims It Isn’t: I’m not dead. The Dead Collector: What? Large Man with Dead Body: Nothing. There’s your ninepence. The Dead Body That Claims It Isn’t: I’m not dead. The Dead Collector: ‘Ere, he says he’s not dead. Large Man with Dead Body: Yes he is. The Dead Body That [...]

The Friedberg Lab is Recruiting Graduate Students

  The Friedberg Lab is recruiting graduate students, for both Master’s and Ph.D. WE ARE:  A dynamic young lab  interested in gene, gene cluster and genome evolution, understanding microbial communities and microbe-host interactions by metagenomic analyses, developing algorithms for understanding gene cluster evolution, and prediction of protein function from protein sequence and structure. YOU ARE: [...]

Using phylogenetics to reconstruct a 59 million year old drug

Good news: Press Release 2011-10-03 The Nobel Assembly at Karolinska Institutet has today decided that The Nobel Prize in Physiology or Medicine 2011 shall be divided, with one half jointly to Bruce A. Beutler and Jules A. Hoffmann for their discoveries concerning the activation of innate immunity and the other half to Ralph M. Steinman [...]

Microbial marketing

An original viral (or rather, fungal and bacterial) marketing campaign for the movie Contagion. Although the film tells the story of a fictional viral outbreak, the marketers of Warner Brothers Canada kept it in the realm of microbiology by teaming up with 25 microbiologists and creating what is probably the first agar-plated billboard, which they [...]

Zombie science roundup

  I am fascinated with zombies. Always have been, but even more so since I took an interest in microbiology. The zombie apocalypse is the best known and best chronicled viral infection which hasn’t happened. But it could happen any day, so stock up on non-perishable food, medical supplies, water purification tablets, chainsaws, machetes, baseball [...]

Shavuot is a microbial holiday

  Tonight is Shavuot. That wonderful holiday which includes midnight studies, water-bombing and dairy products. Mmmmm…. cheese. A food product heavily embedded in the science of microbiology. Cheese is the founding product of the biotech industry (along with beer and bread). So here’s to Lactobacilli and Lactococci which are at the center of the production [...]

In defense of ‘prokaryotes’

Fine, I get it. “Prokaryotes” is a wrong taxonomic term. It’s wrong to lump bacteria and archaea together. That would be like saying “eutoichic” to lump all bacteria, archaea, plants and fungi together because they have cell walls. (“τοίχος” =wall in Greek. My Google Translate-foo is STRONG!)  Still, there are so many things in common among [...]

Crowdsourcing genomics

  Miami University has  joined the National Genomics Research Initiative (NGRI) offered by HHMI Science Education Alliance (SEA) in their Phage Genomics course. The students go directly into the lab, participating in an authentic research experience. In a full-year academic course they: isolate and characterize bacterial viruses from their local soil prepare the viral DNA [...]

Social media used to track disease outbreak

  There are some interesting developments regarding the February outbreak of Legionelliosis which was traced to the Playboy mansion. Reminder: over 120 delegates of the DOMAINFest in Santa Monica, California came down with symptoms of a respiratory illness. The convention included a trip to the Playboy mansion, which later was suspected as the outbreak source. [...]

Book Review: Small and Packs a Punch

A Planet of Viruses Carl Zimmer The University of Chicago Press 109 pages Interesting things happen when physicists decide to go into biological research. They ask questions that biologists generally won’t. For example, viruses have small genomes, but they also have very small storage space in their capsids. Bacteriophages inject their genetic material into the [...]

Ratting out landmines and tuberculosis

  Thanks to John Stevenson for drawing my attention to this one: Giant African Pouched Rats are trained as detectors; a good solution for low-income countries and communities. HeroRATS, as they are called, come in two “models”: landmine detectors and tuberculosis detectors. Rats born in captivity (captured rats are impossible to train) are trained to [...]

Why are there no (or almost no) disease-causing Archaea?

Some microbes are evil minions of Hell (but not all) Quite a few people think that microbes are evil, disease causing minions of Hell that should be eradicated. Supermarkets are handing out sanitary wipes: wipe the handlebar if you want to live, never mind that 90% of the food in the supermarket is worse for [...]
