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 […]

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 […]

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. […]

Thursday Odds and Ends

  A woman in Chesterfield, Ohio robbed a convenience store using her MRSA-infected arm as a weapon.  Warning: graphic picture of MRSA infected arm. Or a zombie limb. You can never know in northwestern Ohio. A US vector biologist got infected with Zika virus which is  a mosquito-borne pathogen causing joint pain and fatigue. He […]

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 […]

Humans draw the LINE at Gonorrhea. Not that it helps.

Ah! What better day in the year can we find […]

Playboy Pleasure Palace Provides Pneumophila?

It seems like an outbreak of Legionnaire’s disease (in a mild form, Pontiac Fever)  has occurred at the DOMAINFest this year at Santa Monica, California. Legionnaire’s disease  is caused by gram-negative bacterium, Legionlla pneumophila. Legionella typically inhabits the water tanks of central air conditioning systems, but any aerosolized  fresh water such as from fog machines […]

The Oxygen Rush: late January, all of February and a Day in November

I have just returned from British Columbia in Canada. I have to admit that their license plate motto is quite accurate: BC is incredibly beautiful. Another thing that struck me is the provincial flag of BC: the Union Jack at the top (OK, it is British Columbia), there are white and blue horizontal stripes, and […]

A new life form? Not so fast

So everybody is excited about the new GFAJ-1 bacterium that Felisa Wolfe-Simon and her colleagues have discovered. A common buzzphrase diffusing through the media and blogosphere is “NASA discovers a new  life form“. (Or, better yet alien life.) Big press conference, and I just finished going through  the article that Wolfe-Simon and colleagues have published in Science. Great […]

Now that’s a f***ing big genome!

It isn’t junk DNA: God just commented out a lot of crappy code as he rolled out releases. — An old bioinformaticians’ joke (Hey, I never said it was a funny joke…) Why are some genomes so big? I mean, seriously. Why would the marbled lungfish with a genome weighing 132.83 picograms (pg) need an […]

Life serves viruses

Sometimes I get the feeling that all life on Earth basically serves as a vehicle for viral replication and propagation. Viruses thrive in all three domains, they embed themselves in all creature’s genomes, they may lie dormant in the genome for eons or decimate whole populations in a few years, and they are the most […]
