CAMBRIDGE, Mass. -- MIT biological engineers have developed a new imaging system that allows them to see cells that have undergone a specific mutation.

The work, which could help scientists understand how precancerous mutations arise, marks the first time researchers have been able to pinpoint the number and location of mutant cells—cells with a particular mutation—in intact tissue. In this case, the researchers worked with mouse pancreatic cells.

DURHAM, N.C. -- Researchers from Duke University, the University of Cincinnati (UC) and the Durham Veterans Administration Medical Center are hoping to find a geographical pattern to help explain why 1991 Gulf War veterans contracted the fatal neurological disease amyotrophic lateral sclerosis (ALS) at twice the normal rate during the decade after the conflict.
