Humans, by most estimates, discovered fire over a million years ago. But when did they really begin to control fire and use it for their daily needs? That question – one which is central to the subject of the rise of human ...

Earth's core reveals an inner weakness

(Phys.org) —The word "core" conjures up an image of something strong. However, new experiments show that the iron found in the Earth's core is relatively weak. This finding is based on x-ray spectroscopy and diffraction ...

Small-scale imaging unlocks nickel ore value

Local researchers are using a unique method of nano-material imaging to more effectively determine the highly variable acid leaching values of Western Australian nickel laterite ores.

Unraveling jellyfish metamorphosis

How does one genome create two completely different body plans in one animal? This was the question Konstantin Khalturin was attempting to answer when he began working on jellyfish. The fascinating story he discovered along ...

Captive hairy marron populace to be bolstered

Researchers studying the hairy marron (cherax tenuimanus) hope to establish a new self-sustaining population of the critically endangered animal by the middle of the year, amid fears it could be extinct in the wild within ...
