Could it be possible to make babies without an egg? Early experiments from a team at the University of Bath suggest it might be. Scientists have succeeded in creating healthy baby mice by tricking sperm into believing they were fertilising normal eggs. Instead, they used 鈥減seudo-embryos.鈥� These "fake" embryos share much in common with ordinary cells, such as skin cells, in the way they divide and control their DNA. These embryos normally die without the addition of sperm to make up a complete genome. Until now, it was thought that only eggs could unravel sperm鈥檚 DNA in order for fertilisation to occur, but these special embryos can do it too. This suggests that other cells are capable of being fertilised.

Cybathlon 鈥� the Bionic Olympics
The first ever Cybathlon takes place in Switzerland on 8 October. This championship for users of assistive technology makes rehabilitation engineering the star. Featuring events such as brain-computer interface races and stair-climbing wheelchairs races, it ultimately could drive innovation in disability technology.

Mapping the Milky Way
The spaceship Gaia launched in 2013 on a mission to create the most accurate 3D map of the Milky Way ever. This will help answer questions about dark matter, how the Milky Way formed and test general relativity. This week the first data dump was released to the world, containing new information on more than a billion stars.

Robot-built DNA
This summer a fully automated DNA-making facility began operation in Scotland. Scientists at the Edinburgh Genome Foundry are teaching robots how to do manual laboratory tasks in order to be able to produce DNA much faster than before.

Fish Lose their Personality When at Risk
When at risk, fish suppress their individual personalities to conform to the group behaviour of others around them. This can make being a bold fish, such as a leader, a very dangerous activity.
