Dialog / How we discovered the oldest human burial in Africa – and what it tells us about our ancestors
How did human uniqueness first evolve among our ancestors, setting us apart from other animals? That is a question many archaeologists are grappling with by investigating early records of art, language, food preparation, ...
Dialog / Early humans used fire to permanently change the landscape tens of thousands of years ago in Stone Age Africa
Fields of rust-colored soil, spindly cassava, small farms and villages dot the landscape. Dust and smoke blur the mountains visible beyond massive Lake Malawi. Here in tropical Africa, you can't escape the signs of human ...
Dialog / Humans weren't to blame for the extinction of prehistoric island-dwelling animals
From the moas of New Zealand to the dodos of Mauritius, humans have hunted many island-dwelling species to extinction in the relatively recent past. But our research reveals humans haven't always necessarily been agents of ...
Dialog / We're all ingesting microplastics at home—here are some tips to reduce your risk
Australians are eating and inhaling significant numbers of tiny plastics at home, our new research shows.
Dialog / Warp drives: Physicists give chances of faster-than-light space travel a boost
The closest star to Earth is Proxima Centauri. It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 ...
Dialog / The Tasmanian tiger was no wolfish predator—it hunted small prey
The thylacine (Thylacinus cynocephalus), commonly known as the Tasmanian tiger, is an Aussie icon. It was the largest historical marsupial predator and a powerful example of human-caused extinction. And despite being extinct ...
Dialog / Fat-footed tyrannosaur parents couldn't keep up with their skinnier offspring, fossil footprints reveal
Tyrannosaurus rex is perhaps the most famous of all dinosaurs. It and its closest kin, a group referred to as "tyrannosaurs," have been embedded in popular culture as powerful and mobile predators.
Dialog / How the amazing engineering of army ants can make us smarter creators
Army ants (Eciton burchellii) are known for their vast foraging raids. Hundreds of thousands of ants flow like a river from their nest site, scouring the jungle as they prey on anything unable to escape the swarm.
Dialog / Prehistoric cave painters might have been 'high' on oxygen deprivation, new study suggests
Long before the emergence of writing, Palaeolithic cave paintings represent the very first examples of human visual culture. They provide a shadowy glimpse of a prehistoric world in which signs were beginning to be used to ...
Dialog / New warp drive research dashes faster than light travel dreams – but reveals stranger possibilities
In 1994, physicist Miguel Alcubierre proposed a radical technology that would allow faster than light travel: the warp drive, a hypothetical way to skirt around the universe's ultimate speed limit by bending the fabric of ...
Dialog / The ocean's 'gut flora': How bacteria affect ocean health from Antarctica to the equator
Aboard an Australian research vessel, the RV Investigator, we sailed for 63 days from Antarctica's ice edge to the warm equator in the South Pacific and collected 387 water samples.
Dialog / Proof of new physics from the muon's magnetic moment? Maybe not, according to a new theoretical calculation
When the results of an experiment don't match predictions made by the best theory of the day, something is off.
