The other day, we attended a lecture called "Toxic and Venomous Marine Organisms." (Or something along the lines of "things that can kill you." You get the drift.) I learned something very important: Australia has many, many creatures that can kill the unsuspecting traveler. Don't get me wrong -- this is a wonderful country, and I love it here. But since we're doing fieldwork here, with a future emphasis on snorkeling, it pays to be careful. So, if you're curious, here are a few of the things I've learned about surviving in Australia -- and a few of the creatures that I'll be watching out for.

Exactly a week ago, I arrived in Brisbane, Australia after close to 40 hours of travel. There was no time to sleep, though -- we arrived at 8 in the morning and got to work after roughly 48 hours with no sleep. When you travel to Australia, you lose a day because you cross the international dateline. Since I’m here studying ecology, I’m going to put up some more detailed information of Australian flora and fauna in my next few posts. For now, however, here’s a basic overview of the ecology of the Land Down Under.

Mosquitoes are as adept at flying in rainstorms as under clear skies. But how is that possible? Wouldn’t rain crush a mosquito to the ground since mosquitoes weigh 50 times less than raindrops?

My group is analyzing the density of Soft-shell clams along the local shoreline in three different places. We have found out since starting the project that the Harraseeket River has an abundance of clams at low tide. This is interesting, because a local clammer told my group and I that a few years ago, it used to be the exact opposite: there used to be no clams at the Harraseeket River and an abundance in the other locations we researched.

Want to help researchers while playing a game? Dr. Jérôme Waldispuhl of the McGill School of Computer Science and collaborator Mathieu Blanchette have designed a web-based video game called Phylo. By playing Phylo, gamers can contribute to scientific research and advance our understanding of the genetic basis of diseases such as Alzheimer’s, diabetes, and cancer. No knowledge of science needed to play!

Fireworks are used for many special occasions including New Years Eve and the Fourth of July. Fireworks originated in the Han dynasty in 200 B.C. When dry fuel ran short, chunks of green bamboo were thrown onto a fire. The bamboo got darker and started to sizzle. After a while, the bamboo unexpectedly exploded. The reason for this is that bamboo grows so fast that sacs of air get trapped inside the plant’s segments, and when heated, the air pockets expand and eventually burst. The bursting air pockets create such loud sounds that they frightening people as well as animals. The Chinese figured that if the noise scared people so much, then it would also scare away evil spirits. So it became customary to throw green bamboo into a fire on the Lunar New Year.

I was lucky enough to interview Dr. Annie Bosacker, a Visiting Assistant Professor of Biology at Carleton College, who has done significant research studying babboons in Gombe National Park, Tanzania. Her main research interest is in the social behavior of primates, specifically how social circumstances influence an individual's exposure to stress. Here, Dr. Bosacker speaks about her previous work, her interests in biology, and what it's like balancing a family and a successful career in biology.

TB is a difficult disease to treat. People are prescribed a combination of many antibiotics to be taken daily for 6 to 9 months. This is a schedule that is hard for patients to follow and hard for their nurses and doctors to administer. Even after beginning the appropriate treatment, some of the infectious cells survive for long periods of time. A team of researchers from the Harvard School of Public Health conducted a study to figure out why some tuberculosis cells are inherently more difficult to treat with antibiotics.

Iron oxide is a component (along with magnesium) of ferropericlase, the second most abundant mineral at Earth’s lower mantle. In the center of the Earth, there is extreme pressure and high temperature. This causes atoms and electrons to squeeze so closely together that they interact differently from the way they interact in the outer layers of Earth. New experiments and supercomputer computations have enabled researchers to discover something interesting about the way iron oxide (FeO) behaves in deep Earth conditions.

On November 30, our final guest speaker of the semester, Anne Madden, gave a talk on her research involving microbes in paper wasp nests. Anne Madden, a graduate research student at Tufts University in Massachusetts, studies the microbes in wasp nests.
