With a human death rate over 50 per cent and an ability to cross species, the Hendra virus that emerged in 1994 had frightening potential.

How a molecular assassin operates
The secrets of a molecular assassin could lead to more effective treatments for cancer and viral diseases, better therapy for autoimmune conditions, and a deeper understanding of the body’s defences enabling the development of more tightly focused immunosuppressive drugs.
A pivotal role was played by 2006 Science Minister’s Life Scientist of the Year, molecular biologist Prof James Whisstock and his research team at Monash University. It was research fellow Dr Ruby Law who finally worked out how to grow crystals of perforin. And the team was then able to collaborate with Dr Tom Caradoc-Davies of the micro-crystallography beamline at the nearby Australian Synchrotron to reveal its complete molecular structure.

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.
