IPY Launch Day



Today is the launch of the International Polar Year (IPY), a large scientific programme focused on the Arctic and the Antarctic from March 2007 to March 2009 (in order to have full coverage of the Arctic and Antarctic). IPY, organized through the International Council for Science (ICSU) and the World Meteorological Organization (WMO), is actually the 4th polar year (1882-3, 1932-3, and 1957-8). It will involve over 200 projects, with thousands of scientists from over 60 nations examining a wide range of physical, biological and social research topics. The priorities are:
  • Changing Snow and Ice
  • Global Linkages
  • Neighbours in the North
  • Discovery
For a detailed presentation of the research you can download the honeycomb chart here.
You can watch
IPY launch events around the world live at the Arctic Portal.

IPCC: The Physical Basis of Climate Change


The IPCC Working Group I - Fourth Assessment Report Summary for Policymakers (SPM) is now approved and available for download here. The contribution describes progress in understanding of the human and natural drivers of climate change, observed climate change, climate processes and attribution, and estimates of projected future climate change. Read the British Antarctic Survey's (BAS) response here.

Via Gristmill: The hot story around this release is the conservative edge to the final product, which does not fully account for the melting of the Greenland and/or Antarctic ice sheets. The report is consensus-based, and as such carefully written and meticulously reviewed. The process is heavily bureaucratic, a maze of international political and scientific red tape, which is both its strength and weakness. While its level of international cooperation attests to its conclusions, scientists have struggled with how to model variables like melting ice sheets. Taking into consideration the Greenland and Antarctic ice sheet is likely to move measurements of the sea level rise from inches to feet or meters within this century. Uncertainties in the science need to be addressed with more research, certainly not the proposed cutback in funding for climate studies. That means public awareness needs to be raised about two things: the missing pieces, and future IPCC reports that include models of disintegrating ice sheets.

The perfect Christmas trip


Pay a visit to the Exploratorium, this December, and take a trip to the field sites surrounding the North and South Poles. Its a celebration for the start of the upcoming 2007-2008 International Polar Year, featuring a special series of Webcasts highlighting the scientific work done at the Poles.

Joe Davis: Genestheticist

Artistic work constructed from synthetic molecules of DNA. The first of these artistic molecules, Microvenus, contains a coded visual icon representing the external female genitalia and by coincidence, an ancient Germanic rune representing the female Earth. The work was carried out with molecular geneticist Dana Boyd at Jon Beckwith's laboratory at Harvard Medical School and at Hatch Echol's laboratory at University of California, Berkeley.

This is something I've been meaning to write somewhere for a really long time, ever since my Boston days, where I came across Poetica Vaginal, a quasi-covert science-art project Joe Davis spearheaded in the 1980s.

So now that blogging is offering the opportunity, here it is:
Genesthetics: Molecular Biology and Microbiology in the Arts
Joe Davis, is (or was?) a research affiliate in the Department of Biology at MIT. He is an artist who has done extensive research in molecular biology and bioinformatics for the production of genetic databases and new biological art forms. He has also constructed sculptural installation pieces, working with laser fabrication in plastics, steel, and stone; laser teleoperator systems; and structural welding in mild steel.
Davis himself has altogether different ideas about how science and art can be coaxed or forced together. For seven years he championed a space shuttle experiment that would have shot a 100,000-watt electron gun into the magnetosphere to create the first artificial aurora.
For Poetica Vaginal he recorded the vaginal contractions of ballerinas with the Boston Ballet and other women, then translated them into text, music, phonetic speech and ultimately into radio signals, which were beamed from M.I.T.'s Millstone radar into outer space. The Air Force soon found out about the million-watt Poetica Vaginal broadcast, as Davis calls it, and shut it down. But the 20-minute message was many times longer than the the first deliberate attempt to say hello to extraterrestrial ham radio operators, a string of 1,679 bits that Carl Sagan and Frank Drake beamed from the giant dish in Arecibo, Puerto Rico, 26 years ago. That message, like every engraved plaque and recorded video disk that NASA allowed on the Pioneer and Voyager space probes, made no attempt to convey what aliens would probably be most curious to know about humans: how we reproduce.
In a keynote lecture at the Ars Electronica exhibition, Davis described his most ambitious transgenic artwork yet: putting an image of the Milky Way into a mouse's ear, an idea inspired by a children's story written 30 years ago by a girlfriend. In order to encode such a large amount of binary information in DNA, he spent years figuring out a general method for archiving computer databases in biological form, a "supercode" that guarantees the infogene will be biochemically stable and yet prevents the host from translating it into protein.
I'm gonna close with a really sad fact I read on Scientific American, that Davis still remains utterly dependent on donations of equipment and expertise from scientists. Because he sells his conventional sculptures to friends at cost and cannot sell his transgenic art at all, even now Davis flirts on the verge of homelessness, with no fixed address. In the fall of 2000 he returned from Europe to find an eviction notice on his door. Much of what he rescued from the sheriff's auction was jammed into a decrepit Volvo station wagon that he obtained in trade for a self-assembling clock. Davis kept Mississippi plates on the car, even though he hasn't lived there in decades, to squeeze through a loophole that exempted it from property taxes. This was published way back in 2001, and I would be really curious to learn of his recent whereabouts...in hope that he is doing well.
