TIGR Scientists Explore Microbes on Shipwrecks and Coral
Researchers embarked on two separate expeditions this week to explore microbial communities on deep-sea corals in the Gulf of Alaska and on shipwrecks in the Gulf of Mexico.
Bioinformatics Resource Center at TIGR to Focus on Biothreat Pathogens
TIGR has signed a five-year, $21.1 million contract with the National Institute of Allergy and Infectious Diseases to establish and maintain a new national Bioinformatics Resource Center for the study of pathogens that are considered biothreat agents or are associated with emerging or re-emerging infectious diseases.
Anthrax Toxin Genes Found in Another Microbial Species
For the first time, researchers have found anthrax toxin genes in a naturally occurring microbe other than Bacillus anthracis, the bacterium that causes anthrax. The microbe that contains those anthrax genes is a strain of Bacillus cereus isolated from a patient with a medical condition similar to inhalation anthrax.
Decoding a Sulfate-Breathing Bug
Paving the way for better methods to protect pipelines and remediate metallic pollutants, TIGR scientists and collaborators have deciphered the genome of a sulfate-breathing bacterium, Desulfovibrio vulgaris, which can damage oil and natural gas pipelines and corrode oilfield equipment.

Scientists Decipher the Rat Genome
An international consortium of scientists that includes TIGR has completed a high-quality draft sequence of the rat genome. Comparing the rat to the human and mouse genomes, the Rat Genome Sequencing Project Consortium reported that nearly all human genes known to be associated with diseases have counterparts in the rat.

Antarctic Epiblog: Leaving McMurdo
Ice formation outside McMurdo Station After we took our samples out at the ice edge, we returned to McMurdo Station for several intense days of demobilization. We had to return all of the large drills, power equipment and camping gear, and spent a considerable time preparing our own gear...
Station IV: The Ice Edge
Our last station in our Ross Sea transect was out at the ice edge, about two miles north of our previous station, Station III. We were interested to see how plankton in the open polynya were different from the phytoplankton we isolated from areas locked in sea-ice. Polynyas are ice-free areas of...
Station III: approaching the ice edge
As we were finishing up our work at Station II, we called MacOps, the radio command center for McMurdo Station, and got a 24 hour weather update: a high to the north of Ross Island was blocking a storm in the south, and we were caught in the middle. The prediction: snow, and lots of it. We had...
Station II, Inaccessible Island
The second storm of our trip hit us while we were packing up Station I for a return to McMurdo. The winds began gusting over 50 miles per hour, and the visibility dropped to near zero. We had already packed up camp, but the orders came in over the radio that Condition 1 had been imposed on the sea...

McMurdo Sound
It took another day for the storm to blow itself out, but by Tuesday the wind and driving snow had abated, and we drove our Pisten Bully back out to our temporary shelter near Cape Evans. It took several hours of digging to clear the snow away from our vehicles, but once we started driving away...
Scientist Spotlight: Greg Wanger
Greg Wanger was 3.7 km below the Earth鈥檚 surface, trapped not only underground but also in a country distant from his native lands of Canada and Liechtenstein. He looked around him. It was very hot and smelled like rotten eggs. As many people do during their graduate careers, Greg pondered the...
Digging out from the storm
The next day offered more snow and wind: we still needed handheld radios anytime we ventured between the warming hut and any of the vehicles. The wind was so strong that snow began drifting up through the dive hole in the warming hut, and the windows completely glazed over with snow. At one point...
Out onto the ice
It took an enormous amount of effort, but on Thursday we ventured out onto the sea ice with our train of sleds and snow machines. The tucker is our strongest (and slowest) vehicle, and it is pulling both our yellow research sled and a pair of snowmobiles. The red Pisten-Bully is pulling a second...
Around Mac-town
We are now fully packed and our mobile research sled is ready to go. We are waiting for some final repairs on the Pisten-Bully which will pull our supply sled. The mobile laboratory sled will be pulled by the Sno-Cat Tucker, which also has cab space for six (riding in the mobile lab would probably...

鈥淒espite reducing the sequence space of possible trajectories, we conclude that streamlining does not constrain fitness evolution and diversification of populations over time. Genome minimization may even create opportunities for evolutionary exploitation of essential genes, which are commonly observed to evolve more slowly.鈥�
