How to view tiny parts of DNA? Make them ‘blink’
A new technique can image nanoscale structures in cells without hurting them. No dyes needed. All you have to do is stimulate them with the right color of light.

Scientists Say: eDNA
Animals may escape traps or nets, but they often leave DNA behind in their environment, giving scientists important clues.

Bananas under attack: Understanding their foes
Fungal blights threaten the world’s most popular fruit. But genetic studies hint at new ways to combat some of these diseases.

Grandparents’ diet could be a weighty issue for grandkids
Australian scientists have found that fat mice can pass on a heightened risk of obesity to their sons and grandsons.

Uh oh! Baby fish prefer plastic to real food
Given a choice, baby fish will eat plastic microbeads instead of real food. That plastic stunts their growth and makes them easier prey for predators.
- Computing
DNA can now store images, video and other types of data
Tiny test tubes might one day replace sprawling data-storage centers, thanks to a new way to encode and retrieve information on strands of synthetic DNA.
- Chemistry
Gotcha! New test stalks diseases early
Chemists screen blood for disease markers by adapting a common DNA test. The test can find disease earlier, when it also may be easier to treat.

Pacific islanders got a double dose of Stone Age DNA
Unlike other people, certain Pacific Islanders inherited DNA from two ancient human ‘cousins.’

Genes: How few needed for life?
Scientists rebuilt a microbe using its old genes. But not all of them. They used as few building-blocks as they could get away with and still have the life-form survive.
