You would not recognise Earth if you saw it 500 million years ago - the lands, oceans, climate and life were all very different. Scientists now have a new map of the deep history of Earth.
Surgeons say minor unintentional damage can happen during surgery, and much of that goes unreported. They say they would be prepared to use robotic tools if they could be shown to help.
Large birds once lived across Australia, only to become extinct around the time that giant marsupials and other megafauna died out during the Pleistocene "ice ages".
Currency first hit the scene thousands of years ago. An anthropologist explains the early origins and uses of money – and how archaeological finds fill in our picture of the past.
This is the second part in a series on how we edit science, looking at hypothesis testing, the problem of p-hacking and how the peer review process works.
Layers and layers of sand and sediment collected in Naracoorte Caves create windows into what Australia was like in our recent past.
Shown as bright orange and pink highlights under X-ray fluorescent light, birds incorporate metals like zinc and bromine into feathers as they grow.

Ordinary grey bird feathers placed under X-ray fluorescence reveal beautiful patterns of elements like zinc, telling a story of feather growth and the environments the birds have experienced.
A simulation of the latest binary black hole merger detected by LIGO. Blue indicates weak fields and yellow indicates strong fields.

Scientists have made a third detection of gravitational waves, again caused by the merger of two black holes. But they think there's something different about the black holes in this case.
Scientists use satellite sensing to find the Earth’s centre of mass.

Rays caught unintentionally by fishing trawlers often spend time on deck before being returned to the ocean. New research shows the stress of this experience affects pregnant rays, and their babies.
The dramatic opening of Star Wars.

Captain Jack Sparrow sails the high seas again in the fifth outing of the Pirates of the Caribbean series. So did the filmmakers get the science right in the action packed adventure?
It used to take weeks to find any of these mysterious signals from deep in space but when the new telescope started looking it found one within days. Then another.
With the right algorithm, scientists can detect how you feel through your Facebook posts.

Simply updating and patching an organisation's computer software may not be enough to fend off another cyber attack. You could engage an ethical hacker to help out.
Immortalised on a stamp, New Zealand’s stout-legged wren went extinct in the 1990s.

The "decision science" approach helps avoid unanticipated consequences of programs to bring species such as New Zealand's little bush moa, Waitomo frog, or laughing owl back from extinction.
Young orangutans are dependent on their mother's milk for many years and that could have an impact on the survival of the critically endangered species.
How much data do you still store only on your mobile, tablet or laptop?

We have never been so connected and we are producing more data than ever before. But how can we manage our data effectively while making sure it remains safe?
