dna packingLongstanding biological mystery of DNA organization now solved
Stretched out, the DNA from all the cells in our body would reach Pluto. So how does each tiny cell pack a two-meter length of DNA into its nucleus of sizeone-thousandth of a millimeter?

lifeSixteen genetic markers can cut a life short
The answer to how long each of us will live is partly encoded in our genome. Researchers have identified 16 genetic markers associated with a decreased lifespan, including 14 new to science.

cropsCrops that kill pests by shutting off their genes
Researchers are now weaponizing RNAi to produce specific RNA fragments that, upon ingestion by insects, shut down a target gene essential for life, thus killing insects.
