'Russian doll' galaxy reveals black holes' true power

Scientists have found a miniaturized galaxy with a single massive black hole, which produces radio jets that are much more efficient than previously thought. The discovery was made using CSIRO's Compact Array radio telescope and reveals that black holes can be both more powerful and more efficient.

Scientists question fisheries health test

A widely used biodiversity indicator in fisheries is found to be an ineffective guide to trends in marine ecosystems, according to a new study published in Nature. The researchers recommend more direct monitoring and the development of trend-detection methods to better assess the impacts of fishing on marine biodiversity.

Broadband coming wirelessly to the bush

CSIRO's Ngara technology offers wireless broadband access to rural areas, with a six-user system capable of uploading data at 12 Mbps. The technology achieves high spectral efficiency, enabling multiple users to upload simultaneously without reducing individual data transfer rates.

CSIRO 'hot rods' old telescope

CSIRO has upgraded a radio telescope at the University of Sydney, boosting its sensitivity and bandwidth to three times more than before. The upgrade demonstrates Australia's technological capabilities and will inform the design of the country's own ASKAP telescope.

A new way to weigh planets

A new way to weigh planets has been developed using radio signals from small spinning stars called pulsars, providing an independent check on previous results. The measurements of planet masses made this new way could feed into data needed for future space missions.

Going high-tech to probe deeper into oceans

The new IMOS ocean-observing array will use advanced technologies like autonomous floats, marine mammals with satellite tags, and underwater gliders to study the open ocean. This data will help scientists understand how the ocean's physical properties influence the marine ecosystem.

New oil detection technique

A new technique allows for fast and accurate detection of petroleum hydrocarbons in soil and rock using a portable infrared spectrometer. This method reduces labor-intensive sampling and processing requirements, saving time and costs associated with assessing and remediating contaminated sites.

Help for new food-zapping process

CSIRO has partnered with German organizations to develop low-energy electron beam processing technology, preserving food's flavor, odor, and nutrients without heat or chemicals. The technology has been successfully applied to Stahmann Farms, Australia's largest pecan nut processor.

Climate change hits southeast Australia fish species

Significant changes in coastal fish species distribution are observed in south-eastern Australia, partly due to climate change. The study identified 43 species exhibiting shifts thought to be climate-related, including warm temperate surf-zone species and range increases for Snapper and Rock Flathead.

Now that's what I call a rat

The CSIRO Australia team has found the remains of a massive 6 kg rat, which survived until around 1000-2000 years ago. The discovery highlights the importance of conserving biodiversity among rodents, such as rats, which play key roles in ecosystems.

Is this the perfect prawn?

CSIRO scientists have developed an improved Black Tiger prawn breed using DNA technology, resulting in record yields of up to 24.2 tonnes per hectare. This breakthrough has the potential to revolutionize the Australian prawn farming industry and increase production from 5,000 tonnes to 12,500 tonnes by 2020.

Natural energy to help power exploration of the universe

The Australian government is funding a project to develop renewable energy technologies for the Murchison Radio-astronomy Observatory and the Pawsey High-Performance Computing Centre. The Sustainable Energy for SKA facility will support solar and photovoltaic technology and direct heat geothermal demonstrator to cool supercomputers.

Scientists offer new take on selective fishing

Scientists propose a new approach to selective fishing that prioritizes ecosystem health and biodiversity, challenging traditional methods. The 'balanced exploitation' approach combines reduced fishing effort with better use of non-target species to achieve sustainable yields while maintaining healthy ecosystems.

World-first study for cleaner aviation fuel

A team of experts has embarked on a groundbreaking project to develop sustainable aviation fuels in Australia and New Zealand. The Sustainable Aviation Fuels Road Map aims to accelerate the development of bio-derived jet fuels that can significantly reduce greenhouse gas emissions from the aviation sector.

New CSIRO soybean a hit in Japan

The Bunya soybean variety is gaining popularity in Japan due to its enhanced suitability as an ingredient in traditional Japanese dishes. Its unique gelation properties make it ideal for producing a range of soy-based foods like tofu and custard.

Old diving tank air extends CSIRO Air Archive

Scientists discover a disused SCUBA tank filled with air in 1968, extending the longest record of greenhouse gases in the Southern Hemisphere. The find uses archived data to analyze propellants, refrigerants and aluminium smelter emissions not widely used in Melbourne at that time.

First signal received by future telescope

The first antenna of the Australia Square Kilometre Array Pathfinder (ASKAP) telescope has received its first radio signals, paving the way for further development. The successful test demonstrates the feasibility of ASKAP's innovative design and sets a promising stage for the future telescope's scientific discoveries.

'Distributed energy' has power to save billions

A new report by CSIRO outlines the potential of distributed energy to significantly reduce greenhouse gas emissions in Australia. Distributed energy systems can provide local generation, efficiency, and demand management, offering an immediate and cost-effective response to climate change.

Endowment fund to support ICT research

A new endowment fund will support ICT research at CSIRO Australia, enhancing the nation's wireless technologies capabilities. The fund will also provide scholarships and fellowships for students across various disciplines, addressing key skills shortages.

CSIRO sets science path for new telescope

The CSIRO has chosen 10 major science projects for its Australian SKA Pathfinder (ASKAP) telescope, which will tackle astrophysical issues and advance the field of astronomy. The projects include a deep survey for star-forming galaxies and a survey for galaxies containing neutral hydrogen gas.

Star-birth myth 'busted'

A team of international researchers has challenged the long-held idea that the ratio of massive stars to lighter ones in star-forming regions remains consistent. They found that this ratio, known as the initial mass function, varies significantly between different galaxies, with some forming more low-mass stars than expected.

Water scarcity started 15 years ago

A new analysis of 30 years of on-ground and satellite observations reveals the onset of water scarcity in southeast Australia around 1993-1996. This finding underscores the importance of good water information for water resource planning and highlights the impact of climate change on the country's current water resources.

Global curbs on overfishing are beginning to work

A two-year study by an international team of scientists found that steps taken to curb overfishing are beginning to succeed in five of the 10 large marine ecosystems examined. This has led to improved fish abundance and reduced exploitation rates, providing new hope for rebuilding troubled fisheries.
