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.

Analysing the genomes of Australia’s iconic marsupials will provide insight into how they turn off and on the development of the early embryo; give birth to very underdeveloped young, and why marsupial milk changes radically over the months of lactation.
This knowledge could lead scientists to new treatments for premature births, better milk production in cows, as well as novel antibiotics. Marsupials fill an evolutionary gap between the distantly related birds/reptiles and the more closely related placental mammals (such as humans and cows).

The OPAL reactor and new neutron beam facility, managed by the Australian Nuclear Science and Technology Organisation (ANSTO) in Sydney’s south, officially opens on Wednesday 18 April 2007.
Costing $400 million to build, the reactor was described by ANSTO’s Executive Director, Dr. Ian Smith as “the jewel in the crown” of Australian nuclear research.

Rising carbon dioxide in the atmosphere is causing ocean acidification, leading to adverse impacts on shell-forming organisms such as sea urchins, cold water corals and plankton.

Watson and Crick’s discovery of the structure of DNA is arguably the greatest of the 20th century. The significance lies in its profound influence on our understanding of the nature of life and in its striking demonstration of the power of two disciplines – physics and biology – collaborating to solve a major problem.

The University of Melbourne’s Departments of Biochemistry and Molecular Biology, and Pharmacology have over recent years identified cone shell venom as a potential treatment for chronic pain in humans.
Researchers continue to develop the research into a commercialised product. One of the venom peptides identified is currently in phase two of clinical trials.

University of Melbourne researchers have isolated a genetic ‘switch’ that can be turned on or off to alter the development of sex cells in plants.
The discovery brings understanding of fertilisation in plants to a new level, and is an important step towards growing greater amounts of food through increased fertilisation of crop plants. Professors Mohan Singh and Prem Bhalla, who head the University’s Plant Molecular Biology and Biotechnology Laboratory in the Faculty of Land and Food Resources, analysed the genetic makeup of white lilies and other flowering plants to identify a germline-restrictive silencing factor (GRSF).

CSIRO is spearheading a $9 million-a-year project to help ease Australia’s current water management crisis.
A new national Water Resources Observation Network (WRON), set up by CSIRO through the Water for a Healthy Country Flagship, is aiming to improve water management, and make a 20 per cent cost saving in the process.
