Twin alien civilizations, the ancient genetics of cancer, and marvellous Maxwell and his wonderful equations
By Hamish Johnston and James Dacey
There is an intriguing article about alien life this week in The Conversation. “Twin civilizations? How life on an exoplanet could spread to its neighbour” is by David Rothery of the Open University and is a popular account of a paper that will soon be published in the Astrophysical Journal. The paper is inspired by the star Kepler 36, which has two planets that are in very close proximity to each other. While the Kepler 36 worlds are not suitable for life, the paper’s authors – Jason Steffen and Gongjie Li – explore possible exchanges of life between two Earth-like planets in similarly close orbits. Rothery explains that debris flung off one of the planets would stand a good chance of finding its way to the surface of the other planet after a relatively brief journey through space.

A little earlier today we hosted a Google+ Hangout about the July issue of Physics World – a special issue about an emerging new research field called the “physics of cancer”. In case you were unable to join us for the live event (or would like to enjoy it all over again), you can watch it again via this YouTube recording.
