To do this they have created the world's smallest 3D glasses, with polarised lens just as we would have when watching a 3D film. By playing films of a fly buzzing around for the mantises, they hope to be able to tease apart the processes going on behind their sight.
Dr Vivek Nityananda, who is involved in the experiment at Newcastle University said: ‘If we find that the way mantises process 3D vision is very different to the way humans do it, then that could open up all kinds of possibilities to create much simpler algorithms for programming 3D vision into robots.
‘We can do this by fooling them into misjudging depth, in the same way that our brains are fooled when we watch a 3D movie.’
Each cell can only deal with one X chromosome working. For males that's not a problem, but females need to choose between their two Xs: one from father, the other from mother. But the precise mechanism for this is still a mystery.
Scientists have now cross-bred two strains of mice: one with green X chromosomes and the other with red. Imaging the different cells in their offspring is helping to reveal unusual patterns. The image below shows the retinas of one mouse: from the left and the right. Yet as far as the X chromosome is concerned, they are almost completely from two different mice.
People in more developed countries are more likely to die from lung, breast, colorectal or prostate cancers. Thanks to animal research there have been many new treatments for these diseases, such as tamoxifen or Avastin, which have helped to lower mortality rates over the past 20 years.
People in less developed countries are heavily affected by stomach, liver and cervical cancers. These are often caused by infections and could be prevented by vaccines or antibiotics. These treatments have been developed through animal research and as they reach the people who need them most, they will prevent millions of cancer cases.
