Biotechnology will be defined here as the application of chemical processes that use either biological catalysts or biological raw materials and that occur in vats or tanks of man's design. We can illustrate each component of this definition with the example of home winemaking, in which the biological raw material is sugar and the biological catalyst is yeast. As the fermentation occurs, alcoho...

Outbreaks of the corallivorous crown-of-thorns seastar Acanthaster planci (COTS) represent one of the greatest disturbances to coral reef ecosystems in the Indo-Pacific, affecting not only coral reefs but also the coastal communities which rely on their resources. While injection approaches are increasingly used in an attempt to control COTS densities, most of them display severe drawbacks incl...
