The 500-metre Aperture Spherical Telescope (FAST) is the largest single-dish radio telescope in the world.
You can't just buy a radio telescope receiver off the shelf. So CSIRO has been hard at work building receivers for the world's largest telescopes using the very latest technology.
Country of origin labels are a good move, but why stop there?
Australia’s new country of origin food labelling will indicate if food is grown or made in Australia and the proportion of Australian ingredients.
The silverlead whitefly is a major agricultural pest.
Invasive species and diseases pose a major threat to agriculture – particularly in the countries that can least afford it.
Some of the many species in the Australian National Insect Collection.
At least 100,000 insects are among the many Australian species still to be formally identified. That's a problem for any biosecurity experts who need to be able to spot potentially invasive bugs.
Intelligent machines are getting better at understanding our conversation.
Human communication is complex, rich in nuances and frequently includes non-verbal signs. That's a challenge if you want an intelligent machine to be part of the conversation.
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.
Bureau of Meteorology
Atmospheric carbon dioxide measurements at Tasmania's Cape Grim and Antarctica's Casy Station have now officially passed 400 parts per million and are likely to stay above that for decades to come.
Moo-ve along: livestock are one of many threats to Australian freshwater ecosystems.
Freshwater covers only 0.5% of the Earth's surface but is home to 10% of the world's lifeforms.
The Solomon Islands are low-lying and vulnerable to changes in sea level.
Sea levels are rising faster in the Solomon Islands – and send a warning for the rest of the world.
Green planet: tropical rainforests have produced more growth in response to rising carbon dioxide.

Half of the world's vegetated land has got greener in the past 30 years, mostly driven by rising CO2.
Data about farms' financial situation as well as the weather could help identify those most vulnerable to drought.
Forecasting drought should be about more than weather – to help those likely to be hit hardest, we need financial and even health data too.
Tasmania’s bushfires damaged pristine bushland and stretched emergency services to the limit.

This summer has seen Tasmania suffer through drought, bushfires, floods and the worst marine heatwave on record. Is this what life under a climate-changed future will be like?
Glacier melt is one of the major contributors to global sea level rise.

Global average sea level has risen by about 17 cm between 1900 and 2005, but we didn't know how much of that was due to us, until now.
CSIRO chief executive Larry Marshall fronts senate estimates in February.

A proposal for the Bureau of Meteorology to take on CSIRO climate scientists is a good idea - but CSIRO needs to make sure nothing is lost.
Glaciers have been a major contributor to sea-level rise.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
Farming land in New South Wales.
Growing population, growing demand for food, climate change: Australia's rural lands are facing a number of pressures. So how can we sustainably use them in the future?
A diet like this isn’t particularly good for your waistline – or the planet.

Climate change will make it harder to eat healthily.
Livestock ‘digestion’ produces nearly 3 billion tonnes of greenhouse gases each year.

Eating less meat isn't the only solution to reducing greenhouse gas emissions from livestock.
Rice cultivation is one of the ways food production pumps methane into the atmosphere.

Fossil fuel emissions are slowing, but another major climate problem is becoming clear: food production.
A study in resilience.

Markets have been on a rocky ride all year on concerns another recession looms. Here are a few lessons we can learn from the last one.
The southern black-throated finch could be brought to the brink by coal-mining developments.
More than half of the remaining habitat for Queensland's southern black-throated finches is potentially subject to mining development. If these mines go ahead, it will be bad news for these birds.
