Contaminants In Life-Saving Drug Detected Using Simple New Method




The blood-thinning drug heparin is highly effective when used to prevent and treat blood clots in veins, arteries and lungs, but earlier this year its reputation as a lifesaver was sullied when contaminated heparin products caused serious allergic reactions that led to a large number of deaths. Now, University of Michigan researchers have demonstrated a simple, inexpensive method for detecting contaminants in heparin, a development that could prevent such tragedies in the future.

Visuals for a stereo (plasma disk? Analog meters?)
I have an old phonograph (edison standing cabinet, phonograph on the top and record storage in a cabinet on the bottom) I pulled out of the trash I'm filling with modern stereo equipment. Where the disks went I want a CD player/record player on a linear actuator to open the lid and rise up, where the horn was I want the midrange and the tweeter and on the bottom a 12" woofer/sub. I have the old record cabinet doors opening to where the sub cabinet will be where I want to put the sliders for an EQ as well as some eye candy. i was thinking oscilloscope but I just don't have the space with the 12" cone.
Now to my question:
Can anyone think of a way to connect a plasma disk to the stereo so it will dance with the music? Any way to connect some old analog needles to the high mid and low so they'll dance amusingly? Or can anyone think of a way to get the old fashioned round oscilloscope look on a flat panel? Low profile is the key point here as I only have a few inches between the doors and the speaker enclosure, but if anyone has any other ideas I'd love to hear them - this is something I've been planning and tinkering with for months now, I'm more than open to anything. I'm expecting to spend a few hundred bucks on this, but supplies aren't limitless. How does the idea of using one of the new $100-200 laptops and some software for visuals sound, possible? I'm just bouncing ideas around and I know make is full of all sorts of creative buggers. Thanks everybody!

Watching The Wine With New Technology
Steeped in tradition, Europe's vintners have found themselves hard pressed to compete with the modern processes used to produce New World wines. Now European researchers are offering the continent's winemaking industry the opportunity to improve quality, save water and reduce pesticide use without giving up age-old practices.

Dr. Michael W. Deem, John W. Cox Professor in Biochemical and Genetic Engineering and Professor of Physics and Astronomy, Rice University, 1-14-08
Genetics, modularity, mutation rate, horizontal gene transfer. Dr. Deem's specialty is statistical mechanics, specifically the computer simulation of complex molecular systems. He works in the areas of evolution, immunology, and materials. Dr. Deem has developed methods to quantify vaccine effectiveness and antigenic distance for influenza, methods to sculpt the immune system to mitigate immunodominance in dengue fever, a physical theory of the competition that allows HIV to escape from the immune system, and the first exact solution of a mathematical model of evolution that accounts for cross-species genetic exchange. Dr. Deem's recent study, published in the December 2007 'Physical Review Letters', found that genetic modularity arises spontaneously because of the selective pressure of a changing environment and the existence of horizontal gene transfer.
