Parkes finds unexpected 'heartbeats' in star

A US-Australian research team has detected radio pulses from a magnetar star, XTE J1810-197, which is giving off extraordinary radio pulses. The finding links this rare type of star with the much more common 'radio pulsars', reordering our understanding of these neutron stars.

The Midas Bug -- the bacterial alchemy of gold

New research published in Science reveals that specific bacteria present on gold grains precipitate gold from solution, providing a biological mechanism for gold formation. The study identified the bacterium Ralstonia metallidurans as responsible for this process, which has significant implications for the mineral exploration industry.

CSIRO reveals how continents can break apart

Researchers have found that continents are significantly weaker than previously suspected, with a narrow weak zone taking up most of the deformation. This discovery explains the origin of flat-lying zones of weakness known as detachment faults, which were not previously understood.

Termites feed through good vibrations

Scientists have discovered that termites use vibrations to determine suitable food sources, a finding that could lead to new methods for reducing termite damage. The study also reveals the 'cocktail party effect' of signal processing, where termites can distinguish between signals from other termites and artificial signals.

Hubble tracks down a galaxy cluster's dark matter

The team reconstructed a mass map of the galaxy cluster using NASA/ESA Hubble Space Telescope data, tracing dark matter's distribution with respect to galaxies. The study reveals that dark matter clumps together in certain regions, supporting the idea that clusters assemble through the merger of smaller groups.

Orphaned star clusters roam the universe

Researchers have identified a population of globular star clusters drifting freely through the vast expanse of intergalactic space, revealing insights into the origins of these ancient structures. The discovery is thought to be the result of galaxy collisions or gravitational pulls that tore these star clusters from their parent galaxies.

Hendra virus has a growing family tree

CSIRO scientists have discovered a long line of viruses emerging from the Hendra virus family, including 15 new paramyxoviruses in animal hosts worldwide. The Australian Animal Health Laboratory holds a collection of all major newly discovered paramyxoviruses.

International award for concrete from waste

Dr Vute Sirivivatnanon has won the Mohan Malhotra Award for his work in turning industrial waste into a useful component of concrete. His research resulted in the development of High Slag cement concrete, High Volume Fly Ash concrete and Silica Fume concrete being used in high-profile construction projects.

'The Dish' tests Einstein's warped space

A team of astronomers has confirmed a key aspect of Einstein's general theory of relativity by measuring the precise orbit of a pulsar. The study used sophisticated instruments to record over 50,000 Gigabytes of data and demonstrated the predicted delay in radio pulses traveling through curved space-time.

E-commerce to cause major shake-up of world transport

Global e-commerce growth is expected to significantly impact the transport industry, leading to a 50-100% increase in intercity freight trips and air travel by 2005. This shift is driven by increasing customer expectations for 'right now' deliveries and the need for more flexible, fragmented, and on-demand transport services.

New way to preserve wood

Researchers at CSIRO Australia have developed a new preservative treatment method using supercritical carbon dioxide, which penetrates wood more effectively than conventional techniques. This process offers environmental and economic benefits, including reduced capital costs and no residual solvent problems.

Sheep thrive in GMO feeding trial

A recent CSIRO Australia trial found genetically modified lupins increased wool growth by eight percent and live weight gain by seven percent in Merino sheep. The modified protein stimulates the production of sulfur amino acids, essential for growth, making it a valuable boost to Australian wool production.

Astronomers wipe clean their cosmic window

An Australian-led team has captured the first picture of the sky in which the Milky Way no longer blocks our view of the Universe beyond. The new survey, HIPASS, used CSIRO's Parkes radio telescope to detect large numbers of small and faint galaxies, as well as giant clouds of gas that give off no light.

Balancing quality and quantity in the vineyard

A new study by CSIRO, Southcorp Wines Pty Ltd, and the Viticulture CRC has found that grape yield and fruit quality can vary widely within small areas of vines. Precision viticulture offers a low-cost way to optimize both yield and quality, leading to improved financial outcomes and environmental sustainability.

New technology tracks missing billions

A new dating method, uranium-helium thermochronology, has shed light on the mystery of missing copper ore at the giant Chuquicamata mine in Chile. The study suggests that part of the rich deposit may have been displaced millions of years ago by tectonic movement along a fault.

Oxygen measurements yield greenhouse clues

CSIRO scientists have measured a minuscule decline in oxygen over the past 20 years, which has shed new light on the role of forests and oceans in absorbing carbon dioxide. The oxygen reduction, just 0.03%, is negligible for human breathing but highlights the importance of plant life in capturing half of the CO2 generated by fossil fuels.

Big Bang Theory Challenged

An Australian-led team of astronomers has discovered a significant number of stray stars, potentially altering our understanding of the universe's composition. These findings suggest that there may be as many stars living in intergalactic space as those within galaxy clusters.

Light Shed On Mystery Horse Disease

Australian scientists have discovered key facts about the Hendra disease, a mysterious virus that infects horses, cats, guinea pigs, and fruit bats. Research shows the virus can be transmitted through contaminated food and cat urine, and is often deadly, even if not highly contagious.

A New Look At Margerine And Health

A CSIRO study found that margarines high in polyunsaturated fats and low in trans fatty acids reduce LDL cholesterol by 11-15%, corresponding to a 20-30% fall in heart disease risk. The study also showed that these margarines can produce a greater fall in blood LDL-cholesterol than other types of margarine.
