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.
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.
Small urban ‘rain gardens’ are popping up all around Australia and Indonesia to keep waterways free from pollutants, stop flooding and erosion, and to grow food.
Although they may look similar to a normal garden, beneath the surface rain gardens are a sandwich of layers of sand, gravel, roots and microbes through which polluted water passes and clean water exits, which can then be used for irrigation or washing.
Assessing ageing bridges just got safer and easier, thanks to a high-tech radar device that fits inside a suitcase.
Developed by Dr Lihai Zhang of The University of Melbourne as part of a collaborative research project supported by The Australia-Indonesia Centre, the IBIS-S radar technology can scan a bridge in 15 minutes from a kilometre away, quickly assessing its condition and stability.
