Genomic signatures identify targeted therapies for lung cancer
... the National Institutes of Health. Mutations in individual cancer-causing genes, called oncogenes, set off a cascade of changes in the activity of hundreds of other interacting genes -- either increasing or decreasing their activity. Rather than looking at each of these oncogenes individually, this new met...An apple peel a day might keep cancer at bay
...apples from the Cornell Orchard and isolated their individual compounds. After identifying the structures of the promising compounds in the peel, the researchers tested the pure compounds against cancer cell growth in the laboratory.

By comparing individual genetic micro-satellites from 171 samples, researchers not only were able to determine if more than one father contributed to a litter, but also which of the known male cheetahs in the study area had sired cubs.
