British supermarket chain Asda said it would be using chicken waste and used cooking oil to power its delivery trucks
It is being hailed as one of the most significant advances in nerve regeneration in a decade. After severing an optic nerve in rats, neurologists have found a way to reconnect it to the brain so that it once again transmits normal electrical signals
Italian archaeologists have discovered one of the world’s best-preserved prehistoric villages, a Bronze Age Pompeii that was buried in volcanic ash near the world-famous Roman city almost 4,000 years ago
A new study of the Martian atmosphere has added strength to a popular theory of why there is so much carbon dioxide in the red planet’s air. Researchers have detected hydrogen molecules in the atmosphere, which had been predicted but not found for decades
An instrument that allows fast, non-destructive wood testing has won its developers the CSIRO Chairman’s gold Medal for the year 2001. SilviScan allows the rapid analysis of wood samples to determine the optimum and most valuable end use of the wood without destroying trees. It can predict paper properties, or the strength of sawn timber from tree structure
Scientists are recommending a slash and burn method to replenish the world’s mahogany trees. Researchers in Indonesia claim planting seedlings in slash and burn fields imitates what happens in nature when a fire follows a hurricane and is better than other ways used by forestry experts to re-establish mahogany trees
Camouflage make-up that can protect troops from the heat of explosions is being developed by British defence researchers. Wearing the cream could mean the difference between a severe burn that needs a skin graft and a far less serious injury
Tiny tubes of carbon may conduct electricity without any resistance, at temperatures stretching up past the boiling point of water. The tubes would be the first superconductors to work at room temperature
Scientists say they can genetically modify whole mosquito populations so that the flies are either susceptible to pesticides, or can’t transmit the malaria parasite. And they would only need to release relatively few GM mosquitoes to kick-start the process
The environmentalist organisation Greenpeace said a high-ranking microbiologist in the US government’s biological warfare program was likely behind the current wave of anthrax attacks that has cost the lives of five people
British rocket enthusiasts say they have successfully tested the most powerful rocket motor ever launched from the UK. The blast-off, to an altitude of 2134m, took place from a remote part of Scotland on 18 November
Thousands of tonnes of waste slag from steel mills can now be recycled into a range of useful products for building roads and pavements, and to substitute for virgin quarried products in concrete
A new gravity map of the Earth suggests that if you want to lose weight you should go to India, where the pull of gravity is slightly less than it is elsewhere on the planet. You would be slightly less than 1% lighter there
Japan’s Super-Kamiokande telescope, which has helped answer fundamental questions about the Universe, is almost destroyed in an accident
Hundreds of beetles will today set about attacking blue heliotrope, a major weed of Australian pastures and crops
Astronomy‘s next great discovery may be found not by telescope, but instead with little more than a laptop computer, an Internet connection and a learned and persistent amateur. In fact, astronomers are already pulling new findings from old data, the start of what some say is a looming change in how science gets done
Imagine a sporting knee guard that tells you if you have landed the wrong way in activities such as AFL football, skiing or netball. Learning to land correctly with its help would mean savings of millions of dollars in medical treatment, particularly for ligament injuries
Australian scientists have unveiled a breakthrough computer tool for the design of a new generation of energy-efficient buildings
Weapons that fire high-intensity sonic bullets could be used by sky marshalls to incapacitate terrorists who try to hijack passenger aircraft. The US Department of Defence is assessing the technology following the attacks on 11 September
People can strengthen their muscles by imagining that they are exercising them, according to study findings presented Sunday at the Society for Neuroscience’s annual meeting in San Diego, California
