A team of doctors diagnosed a boy with a rare genetic disorder by scanning the protein-coding sequences of his entire genome - a first for medicine. The technique reversed an incorrect diagnosis, and led to similar reversals for five other patients.

To pack 2m of DNA into a 6 micrometre nucleus, our genome is packed into super-dense ball without a single knot in it. The shape is called a fractal globule and until now, it was completely theoretical.

The Great Barrier Reef's corals use two genes and a spot of moonlight to synchronise one of the greatest spectacles of the natural world - a mass annual orgy.

As a species, we value fair play. We're like it so much that we're willing to eschew material gains in order to punish cheaters who behave unjustly. Psychological games have set these maxims in stone, but new research shows us that this sense of justice is, to a large extent, influenced by our genes.

The sloth has a surprise passenger hitching a ride inside its body, one that has stayed with it for up to 55 million years - a virus, part of a family that has been infecting mammals for 105 million years.

Scientists have used gene therapy to give full colour vision to adult squirrel monkeys that had been colour-blind since birth, opening up a world of formerly invisible reds and oranges, right in front of their eyes.

Mammals without teeth, or with teeth that lack enamel, also carry broken copies of a gene that is essential for producing enamel. It's a beautiful case study of the decay of genes running in parallel to the loss of body parts.

Japanese researchers have developed a way of using one species of fish as a surrogate parent for an endangered one by transplanting the sexual equivalent of stem cells. If enough of these cells can be preserved, an extinct species could be resurrected.

Plasmodium falcarium, the parasite that causes malaria, evolved from a relative called P.reichenowi that infects chimps today. The parasite jumped from one host to another just once in our history.

Plants from the same species can fail to breed together because incompatible genes from the parents cause the offspring's immune system to fatally turn on itself. These conflicts between otherwise normal genes could split groups of the same plant into separate species.
