Worms help remediate soils
15/11/2008
Earthworms can eat thirty times their body weight of soil each day. Metals in the soil are taken in and change in form, often becoming inert. Mark Hodson is investigating the use of earthworms to help remediate sites degraded by metal contamination.
Daylight saving and energy consumption
15/11/2008
Nicky Phillips reports on the results of a United States survey on changes in energy consumption as daylight saving is introduced.

Animal farming and greenhouse gas emissions
09/08/2008
Beef production has adverse environmental effects. In addition to impact on land and water, cattle, being ruminant animals produce methane, emitted from both ends. This accounts for one-fifth of greenhouse gas emissions. Ellice Mol reports on the latest accounting of greenhouse gases from animal farming, and how these emissions can be reduced.
New baits target feral pigs
12/07/2008
Feral pigs are one of Australia's most destructive pests. Now a pig-specific bait has been developed. Nicky Phillips reports.
Ball lightning
17/05/2008
Bob Crompton describes some theories for ball lightning, the phenomenon where a source of light is observed. The source can be quite small to up to several metres in diameter. Unlike lightning, the effect can last for many seconds.
New approach to building design and transport
08/03/2008
The MIT Design Lab is interested in design problems that have social significance and which don't fit in the usual boundaries of architecture or urban design or engineering.
Centrally controlled light and air in buildings are inherently wasteful and don't cater for the needs of the individual. New technology allowing individual control of light and air in office buildings will increase efficiency and provide people with the environment that suits their needs.
Transport is also in Bill Mitchell's sights. The idea is to develop a lightweight vehicle that is energy efficient, and works on the principle of one-way rental shared use.
