Gene Editing for Conservation Needs In-Built Protection
By Australian Science Media Centre
Researchers have been considering using gene drives to rid New Zealand of invasive pests, but have they adequately estimated the issues and addressed indigenous rights?
Gene drive technology in any implementation is powerful and risky, and thus a precautionary approach to all stages of its development and release is critical. New Zealand already has the most advanced risk management systems in the world for biosecurity and the release of new organisms, including genetically modified ones. Gene editing is only an extension of existing genetic modification which, once established in the wild, usually becomes irreversible.
What the Federal Budget Means for Science
Experts comment on how the 2018-19 Federal Budget will impact research, health and science.
Andrew Holmes is President of the Australian Academy of Science
"This is a good budget for science. It reflects the long-term and strategic approach that is needed for Australia to benefit from science and innovation at a global scale."
Australia’s national supercomputers give scientists across government, industry and universities the processing power for the complex scientific computations needed in an advance society including accurate weather forecasts, drug development, and large-scale astronomy.
First Stars May Have Revealed the Dark Matter Particle
By Alan Duffy
CSIRO’s Murchison Radio-astronomy Observatory has detected a faint silhouette of the first stars after the Big Bang. Its extreme coldness indicates the existence of the dark matter particle.
Radiation from the intense light of the first stars, in particular Lyman alpha, altered giant clouds of gas 180 million years after the Big Bang. These clouds then blocked the light of the afterglow of that Big Bang, the Cosmic Microwave Background (CMB). We see these clouds silhouetted against the fireball all around us. The continuing growth of stars, and the first galaxies, eventually heated that gas until it itself began to glow within just 100 million years.
Ozone Levels Still Decreasing Away from Poles
By AusSMC
While ozone levels in the upper atmosphere near the poles have been recovering, new research has found that the bottom part of the ozone layer at more populated latitudes is not recovering.
The worst ozone-depleting substances are chlorofluorocarbons (CFCs) and other volatile chemicals containing chlorine or bromine. Emissions of these substances have been drastically reduced by international agreement, under the Montreal Protocol, to ban or restrict their production and consumption. As a result (we’d like to believe), the decline in the stratospheric ozone concentration has been arrested and there are some signs of recovery.
Musk’s Mission to Mars

Finkel Review Hedges Its Bets
By AusSMC
Australia’s Chief Scientist, Dr Alan Finkel, has unveiled a blueprint for the national electricity market that “risks falling short of Australia’s task and opportunities in reducing carbon emissions”.
After 'WannaCrypt', should governments stockpile software vulnerabilities?
Should governments adhere in cyberspace to the same rules applied to weapons in the physical world?
The “WannaCrypt” malware has disrupted vital infrastructure in almost 100 countries so far.
Federal Budget 2017-18
Experts comment on how the 2017-18 Federal Budget will impact research, health and science.
Professor Les Field is Secretary for Science Policy at the Australian Academy of Science
"Science has largely flown under the radar in a restrained Budget, with no big spending measures and no major cuts apart from the university funding changes announced last week.
National Science Statement Released
By AusSMC
The Australian government has set out a plan to use science to engage and enrich Australian society. Its objectives are to engage all Australians with science, building scientific skills, produce new research and technology, and improve Australians’ lives through research.
“The National Science Statement sets out admirable objectives, but also shows how the Commonwealth government is failing to put those aims into practice. Most observers would agree that refining and applying science is vital for a civilised future. The Statement reveals some worrying trends.
