A new technique has been added to the CRISPR gene-editing toolbox. Known as PASTE, the system uses virus enzymes to “drag-and-drop” large sections of DNA into a genome, which could help treat a range of genetic diseases.

Fruit flies differ from us in many ways, including the fact that they can't move their eyes relative to the rest of their head. That's not a problem, however, as new research shows that they move their retinas within their unmoving eyes instead.

Soft tissues don’t fossilize well, so scientists have to infer organ anatomy from bones. But an unexpected treasure trove of new information has been discovered in Australia, with a 380-million-year-old fish fossil preserving the oldest heart ever found.
