November 22, 2016

Hosts: Ed Brown, Penny Dumsday, Lucas Randall.

[00:01:28] An extensive series of experiments over 17 years has led to the development of a new genetic map of yeast. Essentially, it’s a reference guide for how to chart genetic interactions within a cell.

[00:07:33] A new study of the Hubble Space Telescope observations has increased the estimated number of galaxies in the universe. The new count stands at two trillion – almost ten times the previous estimate of 120 billion!

[00:15:02] NASA has announced that the successor to the Hubble, the James Webb Space Telescope, has been built. This marks the beginning of two years of intense stressing and testing, before launch in October 2018.

[00:18:32] A new study suggests that Britain’s Beagle 2 Mars lander may have landed successfully, but a subsequent failure made it unable to communicate with Earth.

[00:19:41] A team at University of California, San Diego say they’ve discovered a previously unknown way that bacteria causes acne. They have shown that fatty acids produced by the bacteria inflame the skin cells.

[00:23:12] Last week’s ‘supermoon’ received a lot of excited press coverage around the world. Lucas thinks it may have been a bit overhyped.
