A plastic filling that helps teeth repair themselves could soon cut visits to the dentist. The composite material releases calcium and phosphate that rebuild tooth enamel and can heal small cavities
Forget your traditional Hawaiian skirts. A Belgian agri-design team has headed to greener pastures with clothing made of living grass
A newly discovered asteroid whose orbit around the Sun had only been tentatively investigated was rumoured last weekend to be on a collision course with Earth
An international set of specifications for writing non-verbal human communications in computer code is being drawn up by a US web standards group. Computer scientists backing the project believe that the language could improve cross-cultural communications and might eventually lend itself to virtual reality and artificial intelligence applications
Military and private satellite snapshots of Mount Ararat in eastern Turkey reveal an anomaly that researchers say might be the remains of Noah’s Ark
Foxes, cats, blackberries and bitou bush have not just been disasters for the Australian environment. They are also ethically unacceptable
For the first time, CSIRO and US scientists are using the moon to check and calibrate sensors on board weather satellites. The moon tuned sensors are expected to provide a wealth of improved information about climate change and air pollution
The European Space Agency has built its first ground station in Australia, after lifting the largest satellite dish in Western Australia into place in New Norcia, 134 km north of Perth
Environmentalists and the Queensland government have been angered by the latest moves by the federal government in the approvals process for oil drilling on the Great Barrier Reef
Astronomers at the University of California, Berkeley, have found the star 47 Ursae Majoris in the Big Dipper has at least two planets orbiting it. The latest is a Jupiter-sized planet orbiting at the same distance Jupiter orbits our own Sun. The other is a planet about 2.5 times the size of Jupiter
The speed of light and other constants that scientists have relied on to explain the universe and its formation may not be so constant, according to a new study conducted by an international team of researchers
What comes out of the human body and goes into a toilet is often thought of as an end product. But for future residents of Mars, human waste will need to take on a more vital role
Two six tonne flower pots
at Wagga Wagga are being used by CSIRO researchers working towards a solution for the problem of dryland salinity. The huge pots, or lysimeters, are used to measure the consumption of water by crops.
It’s kind of a drag to track a turtle for months and find out someone ate it
An ambitious three-year mission to catch a piece of the sun and safely return that sample to Earth was successfully hurled on its way into deep space Wednesday atop a Delta 2 rocket launched from Cape Canaveral
Researchers are putting the finishing touches to a $1.25 million supersonic rocket which will be launched at Woomera on 23 October
A system of gigantic ancient valleys — some as much as 200 km wide — has been spotted partly buried under aeons of volcanic lava, ash and wind-blown dust on Mars
Researchers at the University of Zurich using sophisticated 3D modelling have recreated Neanderthal faces — and they are remarkably human and handsome. Despite this, they suggest Neanderthals were a separate ‘sister’ species from modern humans
Storm experts in the US have made a cloud vanish from the sky for the first time. They achieved the feat by sprinkling a water-absorbing powder over the cloud, making it disappear from sight and weather station radar screens. They hope the powder will one day dry up deadly hurricanes and tropical storms
Several scientists have found compelling evidence that Viking Mars landers did indeed discover life on the red planet in 1976. A re-examination of findings relayed to Earth by the probes some 25 years ago, claim the experts, show the tell-tale signs of microbes lurking within the Martian soil
