CRYSTAL CITY:Courtesy of FluidigmFluidigm's TOPAZ 1.96 screening chips employ microscale channels and valves for diffusive mixing of protein and crystallization reagents. Future chip designs will steadily increase parallel throughput.Protein structure determination using X-ray crystallography typically suffers from two major bottlenecks: producing sufficient quantities of material, and finding appropriate crystallization conditions. The TOPAZ™ Crystallizer, released last year by microfluid

A second-generation instrument, the ProXPRESS 2D is "improved with regard to speed, sensitivity, and flexibility," says Alessandra Rasmussen, business unit leader for proteomics and array systems.At the heart of the new imaging system is a CCD camera that offers higher throughput with significantly i

When James Joyce, the great Irish novelist and self-proclaimed artist of life, settled in Zurich in 1915 to escape the War, he little imagined that almost 90 years later people would flock to a pub there bearing his name, to smoke. Joyce wrote most of Ulysses in Zurich and became quite fond of the city, precisely because it seemed the polar opposite, in attitude, of his native Dublin. It was spotlessly clean and homogeneously handsome without any notable landmark or character. Joyce described th
