The Genetic Journey of Max Chatnoir- Bimala Tagore Reporting


Legend: Max Chatnoir and molecules background  
I had the pleasure of interviewing Max Chatnoir, a distinguished Professor of Biology in Texas Wesleyan. She is the “deity” responsible for the creation of the world Genome Island. The build is dedicated to the study of genetics. The island was designed to support genetics classes for university undergraduates studying biology, but anybody interested in science is welcome to participate.
Visitors have access to highly experienced author information, interactive microscopes,  a giant cell model, virtual experiments and variety of topics about inheritance. You will observe methodological objects related to Mendel's life and work and vast information in note cards about genetic information.
Max has made presentations about Genome Island and its use for teaching genetics at conferences sponsored by VWBPE (Virtual Worlds Best Practice in Education) Educause and the Texas Blackboard Users Group.   In Second Life she presented the opportunity to build virtual laboratories in which on line students could perform experiments and data analysis.
In this interview, Max Chatnoir shares with us her valuable experience as a teacher in a virtual classroom and interactive 3D laboratory with relevant information provided.   Although we discussed some of these topics, I would not regard them as special interests of mine, nor do I have any particular expertise in them.  I think it is simplest just to cut this statement. 

Bimala Tagore: More than five years have passed after you decided to create Genome Island. How do you evaluate your project?
Max Chatnoir: I think that virtual worlds like this one are a wonderful place for learning.  You have the advantage of personal contact with another thinking human, via the avatars, but you don't have to be physically in the same place. They can ask whatever questions they have and if I'm not here, they can just IM me, and they'll get an answer the next time I come in. it's a nice combination of personal interaction with the convenience of working online. I wish I could use it for the majors, but they have to actually work with real equipment and organisms if they are going to be scientists. It's my favorite place to teach general education courses. Science for non-majors. The students also seem to find it interesting. I teach my nonmajors course here every fall and sometimes, if we have a bad weather day, I may bring the majors in for a substitute lab. We did a three-point-test cross here once when the flies didn't come in.

Bimala Tagore: The hard path is easier when you strive to learn. I have attained some insight about cell and study of genetics in Genome Island, interactive laboratory environment. What is it about science that interests you the most?
Max Chatnoir: What interests me most is that there is always something new and interesting happening. A new genome gets sequenced, or a new gene is discovered. I always point out to the research students, that no matter what their basic project is, they are doing some kind of genetic analysis. I think one of the exciting areas of contemporary genetics is bioinformatics, which is why I have several bioinformatics activities up on the Bioinformatics platform. Comparing genomes and comparing similar genes in different species. We know that our genes didn't originate with us, but we usually don't stop to think that most of them didn't originate with us as a species.  Our genes are older than we are. A lot of bioinformatics has to do with constructing and studying the information provided in DNA and protein databases. Every time a new genome is sequenced, the information goes into those databases. To learn about what makes us, it's helpful to see what we do and don't share with other species.

Bimala Tagore: Impressive application of biological information. Does genes determine the way of how we could react to our world and even how our mind could interpret the existence?
Max Chatnoir: I do think that genes have something to do with how we experience the world and react to it. Genes encode hormones and receptors and neurotransmitters and their receptors and a lot of molecules relevant to behavior. But it's not all genetics. Experience counts too in my opinion. For example, my sister and I didn't really grow up together because she is much younger.  I was finishing college before she started high school. But it's amazing how similar our preferences are. We order the same thing in restaurants and like the same kinds of fragrances, even though we spend very little time together- Got to be some genetics in there.
The great thing about the human mind is that we don't just behave thoughtlessly, but that is overlaid on what is sometimes called the lizard brain. And I'm not a behavioral geneticist, so I'm not speaking as an expert here. But our minds are a whole additional informational layer laid over our basic biology. It's like a separate genetic code that is better developed in us than in anything else.
Bimala Tagore: Plenty of interesting subjects. Some scientists and doctors have devoted their entire lives with the study of life and living organisms. You have theAbbey” and “Gardens” on your “sim”.  It is a tribute to Augustinian abbot Gregor Mendel. Why is it so important to become acquainted with Mendel?
Max Chatnoir: Mendel was the first person to articulate the "rules of inheritance" for sexually reproducing species. The amazing thing was that he had no idea what a gene might be. He just followed the inheritance patterns. The name "gene" wasn't even in use in his time.  He just called them "elements." Other people had done crosses similar to those Mendel did, but he was the first to offer an interpretation. Each parent provided an "element" for each of their traits. And that the offspring got one from each parent. For Mendel's traits, one of the two parental traits was always dominant to the other (but that isn't always the case);  that the parental elements sorted into the gametes at random and with equal probability. He did the mathematical analysis, and probably nobody could follow his argument at the time he first presented it. Yes, doing the mathematical analysis was unusual for biology. Although William Harvey had done something similar to prove that the blood HAD to be circulating. It couldn't just be made and destroyed all the time -- there was too much of it moving around. But most of biology was natural history.  Like Darwin was doing collection, describing, classifying. If Darwin and Mendel could have got together, they would have been a Force! But they didn't. However, they were roughly contemporary.

Bimala Tagore: Your explanation about Mendel’s positions as founder of genetics is pretty relevant. On the other hand, leading this interview toward ethics aspects, there are numerous thorny sides of genetic research that may lead to ethical and social quandaries. Gene therapy could lead to a dark side. What is your opinion in this respect?
Max Chatnoir: Sure it could. Imagine if we did start making "designer babies. Think of the social inequity, even assuming that all of the biology worked as we anticipated? And it won't. Do we really know enough about ourselves to design whatever we might think an ideal human is?
We can discover a lot about fruit fly behavior, because we don't agonize over the death of a fruit fly, but we can't do that with humans. So we have to depend on the "accidental experiments" of nature. And I'm not sure that even that is very nice.

Bimala Tagore: Regrettably, polemics about ethics are crucial. For this reason, genetics research information should always be open to frank human dialogue and Genome Island can communicate to non-expert too.
Max Chatnoir: I think that it can help with what the average citizen needs to understand about science and scientific thinking. Everybody doesn't need to know how to run a centrifuge, but everybody should be able to understand a scientific argument.
Bimala Tagore: I really appreciate the opportunity for this stimulating interview. Thank you very much.
Max Chatnoir: My pleasure

SL Newser: "Jamm for Genes" Raises Over 300,000 Lindens

Last weekend, the "Jamm for Genes" event raised over 300,000 Lindens. From 10PM Thursday (Aug 2) to close to Midnight on Sunday evening (Aug 5), live musicians performed for the Australian charity at three different clubs, one at a time. On late Thursday, "Lacy's Place" in the Sasha sim started the action. Just as the events there began to wind down 22 hours later, at 8PM the musicians at "The Pocket" at Cassandra began playing.
