Coming soon: Genetically edited 'super bananas' and other fruit?

Posted: 13 Aug 2014 10:10 AM PDT

Recent advances that allow the precise editing of genomes now raise the possibility that fruit and other crops might be genetically improved without the need to introduce foreign genes, according to researchers. This could mean that genetically edited versions of GMOs such as "super bananas" that produce more vitamin A and apples that don't brown when cut, among other novelties, could be making an appearance on grocery shelves.

How spiders fix their webs: Adhesion can vary depending on surface
