So what exactly is a fuel cell, anyway? Why are governments, private businesses and academic institutions collaborating to develop and produce them? Fuel cells generate electrical power quietly and efficiently, without pollution. Unlike power sources that use fossil fuels, the by-products from an operating fuel cell are heat and water. But how does it do this?

The evolution of the peppered moth over the last two hundred years has been studied in detail. Originally, the vast majority of peppered moths had light colouration, which effectively camouflaged them against the light-coloured trees and lichens which they rested upon. However, because of widespread pollution during the Industrial Revolution in England, many of the lichens died out, and the trees that peppered moths rested on became blackened by soot, causing most of the light-coloured moths, or typica, to die off from predation. At the same time, the dark-coloured, or melanic, moths, carbonaria, flourished because of their ability to hide on the darkened trees.

The Nitrous Oxide Research Program is providing world class data  on N2O emissions from different soils under different management  practices, farming systems and climates. It is identifying N2O emission reduction strategies that may benefit farmers.

Tackling greenhouse gas (GHG) emissions is considered to be one of the most serious national and international challenges of our time. Australia has a sizable potential to mitigate GHG emissions and sequester carbon in agricultural production and land use systems.
