Each of our genomes contains millions of one-letter variations called single nucleotide polymorphisms. Researchers have now developed a technique that utilizes these unique features to track cells from different donors.

We are used to thinking of DNA in the form of Watson and Crick's double helix, but a new study suggests there may be different shapes of DNA.

The meat substitute Quorn is derived from a fungus called Fusarium venenatum. A very similar fungus, F. graminearum, is one of the world's most damaging crop diseases. A new genome study shows why one fungus makes food, and the other destroys it.

Vampire bats feast on blood from domestic animals and can pass on blood-borne diseases such as rabies in the process. A new DNA analysis technique will make identifying the bat's victims far easier, hopefully simplifying disease control.
