Dangerous Ideas

Now this is really cool.

Today, Gyroduck commenting on a Journal World article, Drawing on God posted a link (http://www.youtube.com/watch?v=DfPepr...) from You Tube explaining a really puzzling aspect of quantum mechanics. Hop on over to view the video. Also read Gyroduck's comment linking the observations discussed in the video to prayer. Is Gyroduck right to make this connection?

Synthetic Life

One of the hottest areas of biology today is synthetic biology. Synthetic biologists are not content to take a gene from one species and insert it into the genetic material of another species.Instead, synthetic biologists are attempting to build a set of standard building blocks often by synthesizing DNA from scratch. The idea is to have a set of modules that can be plugged together to make the biological equivalent of electrical devices.So just as an electrical engineer designs new circuits by plugging together standard parts on a breadboard, the synthetic biologist attempts to create custom organisms by inserting these biological circuits into cells.The field has progressed to the point where there is an annual student competition at MIT dedicated to designing custom devices called iGEM which stands for InternationalGenetically Engineered Machine Competition. The winners of the 2007 competition have just been announced and they include teams that developed applications of synthetic biology to medicine, environmental sensing, energy and information processing.For example a team from Alberta Canada developed a synthetic set of genes involved in the production of butanol, an organic compound that could serve as a fuel alternative to ethanol.A team from University of Missouri at Rolla, the Missouri Miners developed a biological breathalyser and a biological timer.Synthetic biology is in its infancy and the power of this technology is rapidly increasing, much like the power of computers, so that soon synthetic biologists may be able to construct synthetic organisms entirely from scratch!Readers, how is this dangerous in a positive sense? How about the risks?LinksSyntheticbiology.orgSynthetic Life, Scientific American 2004

Walking Petri Dishes?

Biology is messy. We can't put organisms into neat little boxes and as it turns out, while we think of ourselves as being individual organisms, the truth is a bit more complex. According to an online article from Scientific American, "Humans Carry More Bacterial Cells than Human Ones" , we are probably best thought of as walking petri dishes because of the number and diversity of bacteria that live inside of us. According to the article, scientists used to think that these bacteria were commensals, that is organisms living in or on a member of a different species with out harming or providing much benefit to the "host". But new research reveals that these bacteria interact with us in complex ways and and often significantly benefit us. For instance many of these bacteria appear to help us process our food and help regulate certain aspects of our immune system. So there is a real sense that you and I are really communities of organisms. Now I wonder if the dreaded toe fungus some of us have also benefits us in some way.

Say what?

The name "Dangerous Ideas" comes from a book titled "Darwin's Dangerous Idea" by the philosopher Daniel Dennett. Dennett's thesis is that the concept of natural selection is a sort of universal acid eating away at our traditional intellectual disciplines well beyond its traditional application as an evolutionary mechanism.Science in general is dangerous to traditional ways of viewing the universe. It transforms us. It breaks down boundaries between traditional areas of thought. It challenges our comfortable preconceptions about reality. And it forces us to think in rational and empirical ways that are foreign to emotional and often irrational way that we process information about the world.I use dangerous here in a positive sense. For me science is a liberating force. It doesn't do away with a sense of wonder, a sense of poetry or wonder. But science does not worship mystery but replaces it with a sense of awe at the quirky creativeness of the universe. This blog will focus on science. I will try to stay away from politics and religion...there are plenty of other blogs that do that including my companion blog at The Force that ThroughSometimes I will cross post entries with "The Force" But that blog tends to be much more explicitly poetic, political and philosophical than what I am planning for this space. Also since biology is my thing, expect a bias toward biology and related areas.
