For instance, birds eating calcium- deficient plant material might have less calcium for egg production. Insects could experience weaker exoskeletons. Mammals could have weaker bones or...

Complex gene-swapping spawns a form of lymphoma

...agues should lead to a better understanding of how deficiencies in DNA repair and in the cellular DNA-damage-detection mechanism can produce tumor-causing complicons. "The key point is that these types of cytogenetic lesions are seen in many human carcinomas," said Alt. "Although there have been theories about th...

Brookhaven Lab scientist wins Environmental Mutagen Society Award

...since certain genetic diseases stem from inherited deficiencies in DNA repair. In the early 1970s, Setlow and James Regan, a colleague at Oak Ridge National Laboratory, developed bromouracil photolysis, a method to measure DNA repair that became a standard technique. They incorporated bromouracil, an analog of th...
