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-IDM016789

This 8 minute video segment from Catalyst explains how genetically modified bananas could be the answer to malnutrition in developing countries. Botanists in Queensland are developing genetically modified bananas that can boost vitamin and mineral content and create disease resistant varieties. Issues of lack of genetic ...

• TLF-IDM015487

Have you seen the model of long-chain carbon molecules first developed by Friedrich August Kekulé? This model enabled chemists to make a great leap forward in their understanding of the structure of organic molecules. See how to represent the structure of methane, ethane, propane, butane and octane. Find out how to rearrange ...
