Australia’s oceans are heating up.
The new State of the Climate report outlines Australia's rising temperatures and its regional rainfall declines - and the trends that are locked in for the coming few decades due to greenhouse emissions.
The egg collected in the Central Tanami Desert, Northern Territory, in October 1983.
For more than three decades an egg found in a remote Australian desert was thought to be from a rare nocturnal parrot. So what happened when scientists decided to double-check?
Australia has some of the world’s best ocean energy resources.

Australia has the world's largest wave energy resource – so how do we unlock our ocean's potential?
This cow has the right idea.

Feeding seaweed to cows might just help solve two of our biggest problems: climate change, and feeding the world.
What does it mean when it’s too hard or too soft?
For most of us, the form of stool we excrete can vary widely depending, in part, on what we've been doing.
Western galahs in flight.
When is a galah not a galah? That depends on which scientific name is attached to the Australian bird. There's been some confusion over this, which DNA testing has finally solved.
Could this be the livestock feedstock of the future?
The black soldier fly, Hermetia illucens, could help solve global food shortages by feeding livestock. It can even be used to make diesel fuel.
Australia’s island wildlife is particularly vulnerable to invasive species.
Eradicating feral animals from islands can be expensive, but new research shows where to get the biggest bang for our buck.
Cartier Island marine reserve is part of a network that covers one-third of Australian waters.

Marine parks need to cover large swathes of ocean, but they also need to cover the right areas if they are to deliver the best conservation. New research off Australia's northwest suggests how.
What if these two smartphones could share their learning of their user’s behaviour?
Artificial intelligence gives technology the ability to learn and adapt. But they can learn a lot more if they can share their learning with other smart devices.
Forests and other land-based carbon stores held onto more carbon during colder historical climates.
When temperatures dipped between 1500 and 1750, the world's landscapes responded by storing more carbon. Now, with temperatures climbing, it's possible they will do the opposite and release even more.
Time to take a different road?
The world's use of finite resources continues to rise as global development continues. Can we help poorer nations raise their standard of living without exhausting all of our raw materials?
Computers are getting better at playing games such as chess.
Artificial intelligence gives us machines that can beat humans at games such as chess and go. How long before we see AI surpass human intelligence?
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.
