Heard and McDonald Islands
Heard Island and McDonald Islands are located in the Southern Ocean, approximately 1,700 km from the Antarctic continent and 4,100 km south-west of Perth. As the only volcanically active subantarctic islands they ''open a window into the earth'', thus providing the opportunity to observe ongoing geomorphic processes and glacial dynamics.
Solar Cells Capture Lost Energy
Researchers have created a new type of solar cell that captures some of the excess energy in sunlight normally lost as heat. So far, the new solar cells still convert sunlight to electricity at an efficiency well below commercial solar cells. But if the process can be improved, it could help pave the way to a new generation of solar cells with

Everything you need to know about Australia''s Heard and McDonald Islands
Big Ben has erupted several times over the past two decades. McDonald Island lies 43.5 kilometres due west of Heard Island, and is the major island in the McDonald Islands group. It is a mere 186 metres high and it too has an active volcano. The McDonald Islands are so volcanically active they have doubled in area since 1980.

To amp up solar cells, scientists ditch silicon
Even the newest solar cell designs, tandem devices that have a silicon solar cell below a cell made of a crystalline material called a perovskite, rely on the material. Now, researchers are doing away with silicon altogether, creating tandems from two of the best yet perovskites, each tailored to absorb a different part of the solar spectrum.
