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.

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...
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...
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...
Ice diatoms!
Today has been a day of preparations, as tomorrow we hope to leave McMurdo Station and head out on the sea ice. Our mobile sled is almost ready for deployment: the carpenters who work for the US Antarctic Program are quite amazing, and our sled has filtration racks for separating different...
Sea-ice class
Today Abigail Noble and I took a Hagglund transporter out onto the Ross Sea to learn the basics of sea ice safety and ice dynamics. The sea ice on McMurdo Sound can be 2 meters thick, but this ice is constantly changing, and when you drive along its surface, you can't assume that it is...
Happy Camp
Our project on the Ross Sea will take us far from heated facilities of McMurdo Station, so all members of our team need to attend "Happy Camp", a two day course on snow camping and basic Antarctic survival. Happy Camp is held out on the McMurdo Ice Shelf, and it is an immersion program in...
McMurdo Station
Entering McMurdo is like entering a modern mining town: lots of exposed rock and unpaved streets, above ground utilities and bare-bones architecture. Utilitarian. From the airport we were taken to a briefing room, introduced to our science coordinators, and given our shcedules. Since I am...
Transport to the ice
Wednesday morning started with a 5AM taxi ride to the US Antarctic Program's processing center at the Christchurch airport, where we had to repack our bags and put on our emergency cold weather gear for the flight. Our plane was the C-17 Globemaster III, a large military transport plane more...
Polynya opens in the Ross Sea
A helicopter pilot recently sent us an image of the area we are planning to sample, and the stable sea ice we intended to use as a platform for drilling and sampling is now a giant stretch of open seawater! A large opening like this is a polynya, a term borrowed from the Russian...
Christchurch, New Zealand
Greetings from Christchurch, New Zealand, the anteroom to Antarctica. My colleagues and I have been here for several days now, running last minute errands, getting equipped with cold weather gear, and waiting for a flight south to McMurdo Station. The flight here was remarkable only in it's...
