Author: Jonathan Eisen

I am an evolutionary biologist and a Professor at U. C. Davis. (see my lab site here). My research focuses on the origin of novelty (how new processes and functions originate). To study this I focus on sequencing and analyzing genomes of organisms, especially microbes and using phylogenomic analysis

Scrap food to energy – here we come

Well, congrats to Martin Wu, who is a Project Scientist at Davis in my group for getting his pet project approved as a new Community Sequencing Proposal through the Joint Genome Institute. In this project (see the MIT technology review article here)Martin and Ruihong Zhang a Prof. at Davis are going to do some sequencing of microbes that like in Dr. Zhang’s biogas reactors.

From the MIT article:

“Sequencing these organisms will give us a better idea of who the players are so we can better control the conditions or improve the design to further improve conversion of waste into biogas,” says Ruihong Zhang, the UC Davis bioengineer who developed the system.

and

“We want to compare what kind of microbes are there at different conditions and try to figure out why one [set of conditions] works better than the other,” says Martin Wu, a geneticist at UC Davis who will lead the genomics part of the project.

and

In nature, the microbes that carry out degradation of organic waste and generation of methane exist in a very complex anaerobic community, and individual isolates from the community are hard to grow,” says Jim Bristow, head of the community sequencing program at the Department of Energy’s Joint Genome Institute, in Walnut Creek, CA

Martin has been interested in this area for ages, since his family used to use a biogas reactor on their farm in China. I find this much more sensible than the plans to specifically grow plants to produce biofuels since these reactors simply make use of current solid waste.

Good list of Science Blogs

Check out the list of science blogs at Blog Together. It has many I had never heard of or seen. It has a bit of a bent towards blogs from North Carolina but otherwise it is one of the more comprehensive lists I have seen.

First Ever Synthetic Organism Patent?

Wired is reporting that the Venter Institute has applied for a patent on the first fully synthetic organism (i.e., they synthesized the genome in the lab … I am sure that the organism had to be “booted” up in some way using a living organism).

Wired reports:

Scientists at the J. Craig Venter Institute have applied for a U.S. patent on a minimal bacterial genome that they built themselves. According to the patent application, it’s “a minimal set of protein-coding genes which provides the information required for replication of a free-living organism in a rich bacterial culture medium.”

What do people think? I for one find the patent system completely incomprehensible. I think most biotech. related patents recently have been overly broad and/or represent something that should not be patented. But in this case, I do not know enough detail to really judge but it sounds like at least they did some real work here, which is more than the case for many genome sequence related patents from the past. Given that many places now have patents on mice and other organisms with single genetic knockouts, I do not see how the patent offices could reject a fully synthetic organism. This is not to say whether it is a good idea to synthesize an organism, but I think we are past that point anyway as clearly people will do it.

Another Good Kid’s (and Adults) Activity in Davis – Take the Train to the Train Museum





I have been meaning to try this out for ages. I take the Capitol Corridor train West all the time from Davis to Berkeley and other parts of the Bay Area. But I had never taken it East to Sacramento. It looked from the schedule that it was just 15 minutes or so to Sac and that the Sac station was right near the train museum, which my daughter (2 yrs old) loves (she loves trains trains trains and trains).

So we did it. We went to the Davis station. And took the train to Sacramento. The train ride was great – only about 20 minutes long and my daughter got to see all sorts of cool things (she specially liked seeing the river and going over the Yolo Basin area). And then we were in Sac. And after not being sure where to go, we walked around a corner and right there was the train museum. Which we went into for an hour or so and then headed back to catch the train back to Davis. It was about a 2-2.5 hour outing (not sure exactly when we got back) and was definitely something different for my daughter to do.

Agonizing massive loss for the world and for microbiology – Valley of the Geyseys in Kamchatka mostly destroyed


There has been an environmental disaster of epic proportions in Russia. The Valley of the Geyseys, one of the most spectacular places on the planet – an ecosystem of hotsprings and thermal sites much like that in Yellowstone National Park in the US, has apparently been destroyed by a massive mudslide.

See the news stories

This is a big tragedy for microbiology because Kamchatka has become a site of an enormous amount of really top notch microbiology research and a great place to compare results from those found in other thermal sites like Yellowstone.

TASS reports for example

most of the unique hot water springs in the Valley of Geysers have been damaged beyond repair.

This will affect many important research projects (including mine). For example see the web site of the Kamchatka Microbial Observatory (funded by NSF) on which I have a minor role.

If anyone out there has any additional information it would be appreciated.

PS Thanks to Jenna Morgan for pointing this out.

PPS – Nature has run a news story on this

Best genomics news article title …6 Billion Bits of Data About Me, Me, Me!

Gotta love the title of this article. It captures the essence of the new race to sequence ones own genome pretty well (with Jim Watson and Craig Venter leading the way). Clearly, this type of personal genomic medicine is coming whether we like it or not but, for those interested in getting ones own genome sequenced, here are some things to consider:

1. There will be many mistakes, at least with current methods. Get ready for lots of false positives and negatives relating to risk.

2. People will use it against you. Companies. Friends. Relatives. The government. This is not to discourage people from doing it (well, maybe a little bit). But given our current inability to keep anything important private in this country and our apparent inability to not snoop into people’s lives, this is going to be one overwhelming temptation for many people. Now is clearly the time to move forward with anti-discrimination laws.

3. Having your genome sequence will not automatically improve your health. It could even make it worse (e.g., see false positives above)

4. If you REALLY want to understand some of your biology from your genome, you are going to want to take a peak at the genomes of relatives. Good luck on all the family issues that will come up.

5. Just because Watson and Venter are releasing their genomes to the public does not mean you have to (for medicine it is VERY useful to have a genome associated with an individual … even many individuals, but there is no real need for names to be there)

6. The methods being used may not recover the haplotypes well (e.g., see Keith Robison’s blog).

Great kids activity in Davis – the U. C. Davis Raptor Center








We (me, my wife, my 2 yr old and our 4 month old) went for a visit a few weekends ago to the U. C. Davis raptor center. Our 2 yr old daughter went crazy, never wanting to leave and wanting to see all the birds over and over. The 4 month old loved the tranquil setting (he did not like the screeching hawks, but they have a nice little picnic bench area a bit away from the birds). The Center has a bunch of cages outside with all sorts of raptors, including eagles, hawks, harriers and owls. The also have a litte museum with displays. It is in a really nice setting along the flowing part of Putah Creek south of Davis and is definitely worth a visit.

Here are some pictures

Drug resistant TB and one really bizarre "coincidence"

This whole drug resistant TB travel story just keeps getting more and more outrageous and bizarrely interesting. Certainly it is helping call attention to antibiotic resistance as an issue. I guess that is good. But it is also generating a level of panic that fits in well with the previous panics over bird flu and other scares.

But one thing really strikes me as too bizarre to be a coincidence, although some news stories are presenting it as such. Extreme drug resistant TB is pretty rare in the US. Studying drug resistant TB is also pretty rare among scientists. Yet the father in law of the man flying around the world with this TB is Robert C. Cooksey, a CDC researcher studying, among other things, drug resistant TB (e.g., here is a link to one of his review papers).

The CDC put out a press release implying that he could not have been the source of the infection. Interesting, the release seems to have been removed from the CDC site but can be found at the google cache. Here is the text of the release:

Statement

May 31, 2007

Contact: CDC Media Relations
(404) 639-3286

Statement by Robert C. Cooksey

Research Microbiologist, Division of Tuberculosis Elimination, CDC

First and foremost, I am concerned about the health and well being of my son-in-law and family, as well as the passengers on the affected flights.

I am the father-in-law of Andrew Speaker, who was recently publicly identified as a person infected with extensively drug resistant tuberculosis. I do work at the Centers for Disease Control and Prevention. I have worked at the CDC for 32 years. I´m a research microbiologist in CDC´s Division of Tuberculosis (TB) Elimination, and my work does involve working with a wide range of organisms, including TB. As a research microbiologist, my laboratory work involves identifying the characteristics and features of bacteria.

As part of my job, I am regularly tested for TB. I do not have TB, nor have I ever had TB. My son-in-law´s TB did not originate from myself or the CDC´s labs, which operate under the highest levels of biosecurity.

I wasn´t involved in any decisions my son-in-law made regarding his travel, nor did I ever act as a CDC official or in an official CDC capacity with respect to any of the events of the past weeks.

As a parent, frequent traveler, and biologist, I well appreciate the potential harm that can be caused by diseases like TB. I would never knowingly put my daughter, friends or anyone else at risk from such a disease.

I would ask the media to respect my privacy and that of my family, and I will be respectfully declining all media requests. My thoughts and focus over the next few months will be with my family, and we are hopeful that Andrew will have a fast and successful recovery.

Robert C. Cooksey

I understand his request for privacy, but come on, his son in law apparently flew around the world with a horribly nasty, possibly contagious form of TB. And even if the authorities did not tell him he could not travel, there is no doubt this is something I want reporters looking into. It is entirely possible that it really is a coincidence (son in law having this TB and him working in a lab that probably studies this type of TB) but it is worth investigating this further.
