When chemistry meets culture: Scientists helping save rare art
USA Today – Apr 21, 2007
— When white masquerades as yellow and green might actually be blue a call goes out to Henry DePhillips. DePhillips a Trinity College chemistry professor is among a cadre of specialists using cutting-edge science to solve the color mysteries of paintings and other cultural treasures often several centuries old. Art collectors and museums including Hartford’s Wadsworth Atheneum increasingly are turning to DePhillips and other experts to analyze artwork that has deteriorated over time. With tiny samples invisible to the naked eye they use special microscopes and other equipment to sleuth out the compounds that comprise the color pigments and materials. The result: a glimpse into the long-ago artist’s materials and methods and a road map to preserve or restore the piece as close to its original state as possible.
Extreme bacteria run chemistry of life in reverse
New Scientist – Apr 21, 2007
Subscribe and get 4 free issues. IT SURVIVES on a food so unrewarding it needs help disposing of its waste. Eking out an existence only by turning the normal chemistry of life back to front the bacterium Syntrophus aciditrophicus is one of the most extreme-living organisms known. Now its genome has been sequenced and is yielding clues as to how it survives. It might even help us make hydrogen from waste. Robert Gunsalus of the University of California Los Angeles and colleagues identified 3169 genes in Syntrophus.

Frank Westheimer 95 Who Developed Model Valuable in Biochemistry…
New York Times – Apr 21, 2007
Breslow a professor of chemistry and biology at Columbia said the study “showed us that we had to think much more carefully about how enzymes react within the body” and continues to be widely cited. Westheimer collaborated with Joseph E. Mayer in studying the the structure of organic molecules the building blocks of living things which contain carbon among other elements. In order to better understand how these molecules are assembled from atoms they used physical forces to form shapes in this case rings of carbon and calculated the energy contained within them… Westheimer led a penetrating survey of chemistry for the. In doing so he “helped chemistry departments nationwide make a case for becoming more intellectually diverse” Dr.
The world’s oceans – getting warmer and more acidic
ABC Regional nline – ABC Regional nline – Apr 21, 2007
TranscriptRobyn Williams: Tony Haymet is an Australian a marine scientist now committed to North America. Dr Tony Haymet is the director of the renowned Scripps Institution of ceanography in La Jolla California. He studies the chemistry of the sea. Bob McDonald: And you’ll recall Robyn that the IPCC report the full version on climate was released two weeks ago on Easter Friday with what looked like dire forecasts for the future of the Great Barrier Reef and it’s reefs everywhere that Dr Haymet is concerned about. Tony Haymet: Well the oceans are both warming up and they’re acidifying. So in terms of warming it’s been calculated that about 80% of the heat that human beings have put into the system by putting C2 and other greenhouse gases into the atmosphere about 80% of that heat has ended up in the oceans and as you know the kind of global average temperature reported by IPCC the Intergovernmental Panel on Climate Change just on the 2nd of February was about three-quarters of a degree Celsius. In addition to that that very same C2 which traps more heat on the atmosphere of the Earth also dissolves in the ocean… In addition to that that very same C2 which traps more heat on the atmosphere of the Earth also dissolves in the ocean. I like to call it the Perrier effect. It’s very simple chemistry and physics just C2 dissolving in the surface of the ocean and that makes the ocean more acidic. Bob McDonald: So how much more acidic is it?Tony Haymet: Well the concentration of hydrogen ions the little H+ ions that we associate with acidity has gone up about 30% and that’s a change of the pH by 0. 1 of a unit and I give you the former units because when I say 0. 1 most normal people think that’s not very much but of course we know that pH is a logarithmic scale. So we’ve already observed a change in the pH of 0.
Preston MacDougall: Chemical Eye on a Hokie CAVE
YubaNet – Apr 21, 2007
I marveled at the colorful hills that Blacksburg is fully immersed in and also at the beautiful buildings on campus. Many are made from what locals call “Hokie stone” (a locally-mined dolomite limestone) including those in the stately engineering complex where I gave a Materials Science and Engineering Seminar in the building next to the now infamous Norris Hall. I talked about some of the novel computational chemistry research that I had recently done with scientific visualization researchers at the NASA Ames Research Center in the heart of Silicon Valley. Some of the simulation tools that we used for research on materials that may be useful in nanotechnology were borrowed from aerodynamics research done in gigantic wind tunnels. As odd as this may sound to the untrained ear this is not uncommon in cutting-edge research where great leaps forward can be sharp turns from what you thought was the next logical step. The darker flip-side of course is that technological catastrophes can also blindside you. Perhaps you noted a small chronological detail in this story… nce again my thoughts and wishes are in harmony with the faculty and students at Virginia Tech where the unexpected makes me want to crawl into a CAVE. Preston MacDougall is a chemistry professor at Middle Tennessee State University.
Shaadi ka chakkar screen pe takkar!
Times of India – Apr 21, 2007
Trade circles arewondering how Abhiash ? Bollywood’s newest jodi will fare as a couple onscreen after their marriage. Cinema history has never recorded good examples ofreal-life couples carrying their chemistry onscreen as well for the simplereason that audiences don’t accept them as a hit pair anymore. Never together though some ofour most successful actors did continue to rule the screen when they were pairedwith other stars. Still they are exemplary couples in Bollywood where marriageis a fragile institution. ff-screen they are the golden couples to be emulatedbut on screen these star couples who had sizzling screen chemistry in manysuccessful films somehow fail to recreate the earlier magic. AT tracks downthe record.
