New Biochemical Technology Ready To Retrieve, Purify Heaviest Crude Oil
...ge it presents inextracting it from the ground and purifying it into end products. Crude oil'sphysical properties, such as viscosity, and its chemical impurities affect thecost of recovery and refining, and the amount of waste produced in processing. New air-pollution regulations have tightened the restrictio...... In the late 1950s, Dr. Roizman pioneered in purifying the DNA of HSV anddescribing its unique structure. One of his most important findings was thatgene sequences in HSV differ in unrelated people, but are identical in relatedpeople with the virus. **With Genetic Fingerprints, Dr. Roizman Creates "Mole...Poison-Eating Bugs Strike Gold
.... "We have put them to work in a new system for purifying the waste water, and so far they have managed to reduce the concentration of toxin in the waste-stream 15-fold," he says. "If we can fine-tune the process a bit more, it will make the water completely re-usable by mines that bioleach refracto...Duke Researchers Develop First Treatment For Rare Muscle Disease
...muscle cells." Chen solved the problem by purifying a form of the enzyme that has amodified residue attached to the sugar molecule of the enzyme. The modifiedmolecule is recognized by special muscle cell receptors, which then trigger thecell to engulf the enzyme and direct it to where it is needed. ...
