Finally, some light relief for the Renewable Energy Target

By Iain MacGill

The Australian government has just received a vitally important report to guide their decisions on the future of Australia’s Renewable Energy Target.

But it’s not the RET review report of the Coalition-appointed expert panel, led by Dick Warburton, which was released last week.

99.999% certainty humans are driving global warming: new study

By Philip Kokic, Mark Howden and Steven Crimp

CSIRO finds there is less than 1 chance in 100,000 that global average temperature over the past 60 years would have been as high without human-caused greenhouse gas emissions

There is less than 1 chance in 100,000 that global average temperature over the past 60 years would have been as high without human-caused greenhouse gas emissions, our new research shows.

Published in the journal Climate Risk Management today, our research is the first to quantify the probability of historical changes in global temperatures and examines the links to greenhouse gas emissions using rigorous statistical techniques.

Science and the Coalition: two big policies, one year and no minister

By Matthew Bailes

On science and technology, the Abbott government is somewhat of a paradox.

On one hand, the government passionately believes that deregulating the university sector is essential. By taking caps off fees it hopes this will generate the necessary income to transform the higher education sector into an international powerhouse.

There are no free rides to the future: Australia's Chief Scientist

By Ian Chubb

A transcript of the 2014 Jack Beale Lecture on the Global Environment hosted at the University of New South Wales.

Tonight I want to talk about the future.

I know that it’s not a novel thing to do; not even a new thing to do. Indeed, Hansard records that the word “future” was used 848 times in the Australian Parliament just last June; a number that appears to be the highest monthly count on record.

Australia's astronomy future in a climate of cutbacks

By Lewis Ball

The future looks very bright for Australian radio astronomy but it was somewhat clouded earlier this year when CSIRO’s radio astronomy program took a dramatic hit in the Australian federal budget.

CSIRO has cut its funding for radio astronomy by 15%, down A$3.5 million to A$17 million for the 2014-15 financial year. The result will be a reduction of about 30 staff from the plan of just three months ago.

Fast-tracking access to experimental Ebola drugs

By Glenn Marsh

Several therapeutic treatments are in experimental phases of testing and show great promise in treating Ebola virus infections in animal models.

The current outbreak of Zaire Ebola virus in Western Africa is the largest ever recorded. More than 1800 people have been infected and nearly 1000 people have died. But while drug therapies are close to being available, they may not be ready in time for the current outbreak, even if safety trials are fast-tracked.

Coal seam gas emissions lower than US: first Australian study

By Damian Barrett and Stuart Day

A CSIRO study offers the first indication of fugitive emissions from coal seam gas wells under Australian conditions.

One of the most common questions Australians ask about coal seam gas is whether the gas wells leak – and if so, how much?

In the first Australian study of its kind, new CSIRO research now gives an indication of how much those “fugitive emissions” might be, and how we can start to reduce them.

Why so many domesticated mammals have floppy ears

By Don Newgreen and Jeffrey Craig

Take a look at several domesticated mammal species and you might spot a number of similarities between them, including those cute floppy ears.

The famous naturalist and evolutionary theorist Charles Darwin even observed in the first chapter of his On the Origin of Species that:

Not a single domestic animal can be named which has not in some country drooping ears […]

And it’s not just the ears. Domesticated animals share a fairly consistent set of differences from their wild ancestors such as smaller brains, smaller teeth, shorter curly tails and lighter and blotchy coats: a phenomenon called the “domestication syndrome”.

Brain Versus Brawn: Evolution of the Bubble-Headed Weakling

By Darren Curnoe

Differences in metabolism explain why humans evolved brains while apes evolved brawn.

One of the most important questions we can ask, and one that continues to take up much of the time of scientists, philosophers and the religious minded alike is, why are humans so different to the rest of the living world?

Philosophers and physicists have even celebrated the appearance of humans 200,000 years ago on the African savannah as marking the arrival of consciousness or self-awareness for the universe.

Born this way? An evolutionary view of 'gay genes'

By Jenny Graves, La Trobe University

New research supports this claim that particular genes influence sexuality.

The claim that homosexual men share a “gay gene” created a furore in the 1990s. But new research two decades on supports this claim – and adds another candidate gene.

To an evolutionary geneticist, the idea that a person’s genetic makeup affects their mating preference is unsurprising. We see it in the animal world all the time. There are probably many genes that affect human sexual orientation.
