Ocean acidification threatens marine ecosystems

Ocean acidification, caused by increasing amounts of atmospheric carbon dioxide dissolving in the ocean, poses a serious threat to marine ecosystems.

Increasing acidity affects the ability of some planktonic organisms to form shells, and is expected to change the species composition of plankton, with flow-on effects to higher levels of the food web.

Are forests really the carbon sink we need?

Ivett_300x180Evidence is building to suggest that our forests may not be the climate change ‘get out jail free’ card we all want.

Australian Rivers Institute’s Assoc. Prof. Peter Pollard has researched rainforest lakes and rivers to test a provocative theory. The respiration of bacteria living and ‘breathing’ in these freshwater ecosystems is a major pathway for the return of rainforest carbon back to the atmosphere as the greenhouse gas carbon dioxide.

A new $1.5 million super resolution microscope is producing spectacular images of bacteria and parasites, and making Australia a world leader in microscopy.

The DeltaVision OMX 3D-Sim Super-Resolution Microscope, recently acquired by the University of Technology, Sydney (UTS), is one of only two in the world.

Kangaroo bacteria fight cancer

Kangaroo 5Australia’s iconic kangaroo may hold the secret for the war on cancer. Assoc. Prof. Ming Wei from the Griffith Institute of Health and Medical Research is using commensal bacteria found in kangaroos to develop anti-cancer agents that are expected to be effective in combating solid tumours, which account for up to 90 per cent of cancers.
