This six and a half minute video segment from Catalyst shows how understanding bees process information from their compound eyes may help in designing better surveillance systems. This program is useful for discussion of the methods of scientific research into behaviour and perception.

• TLF-IDM016450

This eleven and a half minute video segment from Catalyst is an excellent example of how science research can change our understanding. Some rare people who actually want their limb removed and will go to extraordinary lengths to do so are now regarded as experiencing a neurological phenomenon rather than a psychological disorder.
