Phylogenomics has shown that as mammals evolved, the lice that feed on them evolved at a similar pace, resulting in family trees with parallel branches and twigs.

Researchers from the Francis Crick Institute, Royal Marsden, UCL and Cruces University Hospital have found that cells from different parts of kidney tumours behave differently, and surprisingly, cells within the centre of a tumour are the most aggressive and have the highest chance of spreading around the body.
Cancers can spread to other parts of the body, with cells taking hold as secondary tumours which make the disease much harder to treat. Understanding the mechanics of this spread, a process called metastasis, could lead to new treatments that block this migration.
In their multidisciplinary study published today (17 May) in Nature Ecology and Evolution, scientists led by the Litchfield lab at UCL and the Turajlic, Swanton, and Bates labs at the Crick, analysed 756 cancer biopsy samples from different regions within tumours from the TRACERx Renal study.
