New blood test uncovers individual risk for lung cancer
...mes whose function is to repair DNA. These enzymes scan the DNA and detect damage using sophisticated sensor systems. Upon detection of damage, the enzymes perform an "operation" on the DNA, cutting out the damaged part and replacing it with a new DNA part. Thus the efficiency of the repair systems is cri...PET scans used to determine progression of HIV infection

The researchers believe PET scans could lead to greater understanding of HIV disease and new methods for treating the infection. Their findings are published in the September 20, 2003, edition of The Lancet...$9.4 million NSF grant backs UCSB-led effort in bio-image informatics

"If we were to scan someone's brain each second during the 10 seconds it took that person to walk over to a chair and sit down, we would end up with millions of variables," Hanson said. To monitor a human brain over the period of an hour, second to second, would take va...LabNotes -- Research highlights from Pacific Northwest National Laboratory
