The discovery also offers clues on the search for life on Mars.
Engineers from the University of New South Wales have managed to add to the growing benefits of using perovskite solar cells. Aside from being flexible, easily manufactured and cheap, they have now broke a world efficiency record.
Scientists say climate change is responsible for the recent destruction of kelp forests off the southwestern coast of Australia.
A huge number, 150,000, of Adélie penguins have disappeared from Antarctica's Commonwealth Bay. A recent study tied the occurrence to a giant iceberg that grounded in the area, isolating the penguins and causing them to starve to death.

Male peacock spiders use of exotic dances, vibrations, and colors in courtship displays, but it takes extra dedication to win over females who don't impress easily.
After studying groundwater resources from the Illawarra plateau of New South Wales, researchers have developed water-tracing methods that will help detect future changes in water flow and quality.
New statistical analysis has provided a very precise record of climate change in the Pleistocene, including its effect on mammoths, say researchers.
