Comet ISON was billed as the "Comet of a Lifetime", but was more fizzle than sizzle. But even though it burned up in the sun, it's mysterious approach could give astronomers valuable insights into comet behaviour.
An amazing result from a mice experiment in Atlanta suggests mice can 'inherit' memories from their fathers, and even their grandfathers.
Researchers have successfully sequenced the oldest known human DNA - 400,000 years old - and uncovered further mystery about human ancestory.
The male contraceptive pill could be a step closer thanks to an unusual approach taken by Australian scientists. Instead of looking at hormonally controlling sperm production, they are looking at controlling the release of sperm at orgasm.
China has launched Chang'E 3, a probe with a rover set to land on the Moon. If successful, China will be the third country ever to land a craft on the moon.

Jo Benhamu joins us to talk about a new trial she's conducting to improve radiotherapy for prostate cancer.
More progress resurrecting the extinct gastric brooding frog.
Scientists in Spain have received funding to test whether an extinct mountain goat can be cloned from preserved cells.
The temperature of the lab could potentially skew results of mice-studies. The mouse immune system is stronger at warmer temperatures than most labs are kept at.
NASA has plans to send plants to the moon, to grow in a 3D printed miniature greenhouse.
We pay tribute to Frederick Sanger, a two-time Nobel Prize winner and the 'father of genomics'.

Launch of the MAVEN probe to Mars, to investigate what happened to the red planet's atmosphere.
Richard Lenski's long-term evolution experiment shows no sign of stopping. One of the longest continously-running scientific experiments demonstrates that bacteria evolves and at an increasing rate.
The 'clean-rooms' where spacecraft are built are the most sterile places we can make. But a new species of bacteria has been found in two such clean-rooms - not exactly thriving, but not dead either...
It's well established that modern dogs are an evolutionary off-shoot of wolves, but there's a lot of debate about when and where they branched off. With theories suggesting China, Europe and the Middle East as being the sites of the separation, it's an ongoing question.
