Episode notes

Scientists have found a new organ in the intestines of fruit flies. Called PXO, it seems to be involved in phosphate and probably storing phosphate acting like a reservoir. This is important because phosphate is vital for growth - but not so well studied in animal tissues or cells. Take over the bones of that research in proceedings of the Royal Society B.

00:45 Making a more diverse human genome

The first draft of the human genome ushered in a new era of genetics research. Since its publication, researchers have constructed ever more accurate ‘reference genomes’ – baselines against which others are compared. But these are based on the DNA of a small number of people, and don’t represent the genetic variation known to exist across human populations. To address this, a consortium of researchers have published the first draft of a ‘pangenome’, which combines the genomes of 47 genetically diverse individuals. This draft provides a more complete picture of the human genome, and is the starting point for a project that aims to include sequences from 350 individuals.
