Bacteria that cause tumours in plants modify plant genomes by skilfully exploiting the plants' first line of defence. Utilising the plant's own proteins, bacterial genes infiltrate first the nucleus then the plant genome, where they reprogramme the plant\'s metabolism to suit their own needs. This process was published in Science.
The ...

A person is 100 times more likely to get cancer at age 65 than at age 35. But new research reported today in the journal "Nature Genetics" identifies naturally occurring processes that allow many genes to both slow aging and protect against cancer in the much-studied C. elegans roundworm.
Many of ...
