Brain cells in older Drosophila tend to have more than two complete sets of chromosomes, and that polyploidy most likely has a protective function, a study shows.

These mobile genetic elements can wreak havoc on the genome. Researchers are now trying to understand how such activity contributes to the aging process.
Researchers find that temporary double-stranded DNA breaks commonly result from normal neuron activation—but expression of an Alzheimer’s-linked protein increases the damage.
