Plants need water, but if that water also comes with a hefty dose of salt it can kill the plant. But the ice plant, Mesembryanthemum crystallinum, has a clever way of storing salt in special cells, allowing it to thrive in saline coastal areas.
Dating of ancient human teeth discovered in a Sumatran cave site suggests modern humans were in Southeast Asia 20,000 years earlier than previously thought.
The international research, led by Dr Kira Westaway from Macquarie University and published in Nature, has pushed back the timing of when humans first left Africa, their arrival in Southeast Asia, and the first time they lived in rainforests.
Researchers have found that coral reefs may play a key role in cloud formation. Now they’re working to make climate modelling more accurate.
Australian and international scientists, led by QUT’s Professor Zoran Ristovski, spent a month in late 2016 collecting data on airborne particles emitted from the Great Barrier Reef, which they are now analysing.
Drones could be the key to safer beaches for swimmers, surfers, snorkelers—and sharks.
An intensive trial monitoring New South Wales beaches has shown that drones mounted with cameras can reliably detect the big fish.
Mangroves help fight climate change but they’re at serious risk from its effects. That’s one of the findings from a study of a massive mangrove dieback that occurred in late 2015.
Local fishermen reported mangroves were dying along hundreds of kilometres along the Gulf of Carpentaria coastline, an area known for its barramundi fishing and high value commercial fisheries.
This caught the attention of Dr Damien Maher of Southern Cross University, who is interested in the chemistry of mangroves—how they store carbon in their soils, remove planet-warming nitrous oxides from the atmosphere, and neutralise ocean acidification by releasing alkaline chemicals into nearby waters.
