  • Scientists have been able to create mice with a percentage of human brain cells, by injecting human stem cells into mouse embryos. This has been done in an effort to make realistic models of neurological disorders like Parkinson's disease. The percentage of human brain cells is so small that it doesn't remotely come close to "humanising" the mice, although it does add to ethical concerns about this type of research.

  • Read about how magicians trick the mind.  Scientists have devised a myriad of weird and wonderful ways to test this - to show how much people miss right in front of their eyes. Every moment, the mind is bombarded with a cacophony of sights, sounds, smells, tastes and physical sensations. Your consciousness has to continually meld all this data together and make sense of it. So it takes a few shortcuts and unless a major change occurs to grab your attention, your brain will not refresh the scene. In short, you see what you expect to see - and that is very helpful to an illusionist. .
