Kangaroos can’t fart. They convert the small quantity of methane they produce into an energy source which their body reuses. Scientists hope that they will be able to transfer the bacteria that causes this in kangaroos to cows, to reduce methane emissions to save the world from the latest fashionable catastrophe: global warming.

The PhD is not the highest degree a person can receive. There is also a Doctor of Sciences (DSc/ScD) and Doctor of Letters (DLitt/LittD) which is normally awarded in Britain, Ireland, and the commonwealth nations though it is occasionally awarded in the United States. It is normally awarded for a substantial and sustained contribution to the art to which it applies – for example science and literature. Mark Twain was awarded a Doctor of Letters by Oxford University. Just to add to the confusion, there is also a PhB which is a bachelor of philosophy which is equal to a Masters degree despite its name.
