More than 2 200 years ago, legend has it, Archimedes got into a bath and had a lightbulb moment. He worked out that you could use the amount of water it displaces to measure the volume of an irregularly-shaped object. He was supposedly so excited about this that he jumped out, and ran, dripping wet and naked, down the street yelling ‘Eureka!’ (Ancient Greek for ‘I’ve found it’).
This story might not be entirely true, even though it deserves to be. But something that is unquestionably true is that several of our peeps had their very own Eureka moment, winning an Australian Museum Eureka Award, while fully clothed.
Here’s what they did to earn it.
WUE Initiative team (James Hunt, John Kirkegaard, CSIRO and Stuart Kearns, GRDC)
Department of Agriculture Landcare Eureka Prize for Sustainable Agriculture.
One of the biggest limiting factors for Australian agriculture is water. CSIRO and the Grains Research Development Corporation have been working on a five-year research project – the WUE Initiative – to increase water use efficiency in grain farming.
The results showed that it’s possible to a significantly improve water use efficiency in the southern and western growing regions, demonstrating an increase in the long term average winter crop yield without increasing input costs, and lifting average Australian wheat yield by around 25 per cent across all regions.
Two thirds of the yield gains from improved WUE come from pre-crop management.
Hendra Virus Research Team
Australian Infectious Diseases Research Centre Eureka Prize for Infectious Diseases Research
Well, what can we say? Horses and their owners all over Australia are very, very grateful for Equivac® HeV. This vaccine was the culmination of years of painstaking work by the Hendra Virus Research Team. It was also a novel approach to preventing a disease that kills humans – developing a vaccine for the horses that pass it on to humans, and who are also vulnerable to it. Hendra Virus has killed four out of the seven people it has infected – and with the help of this vaccine, they might be the last.
Science Photography Prize
Mark is a microscopist in CSIRO’s Bioimaging & Plant Development unit. He has developed a technique using a scanning electron microscope, to look deeper into plant cell tissues. His images speak for themselves.
We’d also like to congratulate the other CSIRO finalist at the Eureka’s last night:
The AIBL Research Team (CSIRO Lead Scientist Lance Macaulay)
University of New South Wales Eureka Prize for Excellence in Interdisciplinary Scientific Research
This – the Australian Imaging, Biomarker & Lifestyle Flagship Study of Ageing – is a truly massive multidisciplinary undertaking. It’s a long-term study to discover which are the biomarkers, cognitive characteristics, and health and lifestyle factors that determine whether a person will develop symptomatic Alzheimer’s Disease. It has more than a thousand participants, and is now showing positive results both in detecting biomarkers and developing diagnostic tests.
And finally, a congratulations to the winner of the CSIRO Leadership in Science award, Professor Terence Speed from the Walter and Eliza Hall Institute of Medical Research.
At the Institute, the team that Terry leads uses computational mathematics to help researchers interpret massive amounts of experimental data.
Terry’s extraordinary leadership in the field extends well beyond the walls of the Institute. His techniques for improved DNA data analysis are distributed free-of-charge and used by thousands of researchers around the world. He is one of the world’s most cited scientists—not only in mathematics, but in computer science, biology and biochemistry.
Congratulations to all the finalists and winners of this year’s Eureka Prizes. Archimedes would be proud.

Mmm . . . lovely! A hot Indian curry is simmering away on the stove on a wintry night. The smell of spices fills the kitchen. One of the spices is turmeric, from the ginger family. Its vibrant yellow colour comes from the compound curcumin which is finding a use in clinical tests for Alzheimers disease (AD).
Who knew? Soon everyone will! We’re presenting our research this week at a major conference in Copenhagen, AAIC2014.
A clinical trial of the spice-infused eye test is being led by our own Dr Shaun Frost and team, with WA’s Edith Cowan University, US company NeuroVision Imaging, and the McCusker Alzheimer’s Research Foundation in Perth. Several hundred volunteers have taken part. They include healthy people, mildly cognitively impaired people and patients with AD. It’s all part of the Australian Imaging Biomarkers and Lifestyle study of Aging (AIBL)
The trial asks volunteers to come along to two visits for retinal fluorescence imaging, ie an eye scan. This is quick and painless. Patients sit in front of a specialised camera and a photo is taken of the retina at the back of their eye.
Between visits, volunteers eat some curcumin which binds to beta-amyloid plaques, the sticky proteins that indicate Alzheimers, and fluoresces. The plaques (if there are any) show up in the eye scans as bright spots which can be counted and measured. The data is then used to calculate a special number for each patient, a retinal amyloid index (RAI), and compared between healthy, mildly cognitively impaired and AD patients.
Encouragingly, as we announced this week, early results show the amount of plaque in the retina closely mirrors the amount in the brain. If confirmed, retinal imaging may be the beginnings of an easy, non-invasive test for early detection of AD. Combined with results of cognitive tests and other markers it could help doctors diagnose AD more confidently.
Eye scans like this also find plaques when they’re smaller than the ones in brain scans, potentially finding signs of AD earlier – maybe up to 20 years before cognitive symptoms appear. If diagnosed, AD patients could start treatment sooner and have regular eye scans to see which treatments work best for them.
Brain imaging on the cloud
From curry to the cloud. More research presented this week is about more accurately interpreting brain images sometimes used to diagnose AD.
To get a brain scan, a patient lies on a bed in a large machine like a Magnetic Resonance Imaging (MRI) or Positron Emission tomography (PET) scanner. These machines record a series of images through the brain, which are then visually checked by a radiologist who compiles a report for the patient’s doctor.
This visual inspection can be subjective, tedious and time consuming. But recent advances in scientific computing and machine learning allows systems to accurately measure features of the 3D scan, such as brain size or concentration of a tracer molecule, that support a diagnosis.
Using these techniques, a new trend is emerging for improving radiologists’ productivity. Scanners and specialised medical software can report quantitative values and compare them to the values expected for normal, healthy patients – just like blood test results from a pathology lab do.
Our researchers, led by health imaging specialist Associate Prof Olivier Salvado, have just released a new cloud computing application, MILXCloud, that automatically delivers standardised radiology reports.
Users will be able to upload a PET scan and within 15 minutes be emailed a one page quantitative report showing a diagram of the brain with colour coded values compared with what’s normal. This data will help support diagnosis by the radiologist and enhance delivery of eHealth services.
Whether it’s curry or the Cloud, the future of Alzheimer’s detection sure looks bright.

By Cathy Foley, President of Science and Technology Australia
As International Women’s Day approaches on March 8 and my time as NSW Premier’s Woman of the Year draws to a close, I have been thinking about diversity in the workplace, and in particular, the relationship between diversity and innovation.
Science and technology that lead to innovation are critical for the changes that lead to a better quality of life, greater business opportunities and a happier, healthier and more equitable society.
We don’t have to look far from our own backyard to see examples of this. The rapid global expansion of wireless communications is in part possible because of the now widely acknowledged work by John O’Sullivan and his team at the CSIRO. Wi-Fi is now estimated to be used in more than 3 billion devices worldwide.
Given the huge benefits that innovation can bring – economically and socially – we should be doing everything we can to encourage environments where this type of thinking and practice can thrive. One of the most effective ways to do this would be achieve gender balance in our innovation system.
The gender balance
There is strong evidence that companies operating with a gender-balance actually enhance their innovation quotient and gain a competitive advantage.
Reports also suggest that advances in gender equality correlate positively with higher Gross National Product (GNP) and that increasing women’s labour force participation and earnings generates greater economic benefits for a family’s health and education. Surely this can only be a good thing.
So where exactly are we at? As a nation we have achieved great things. Last year Australia was named the country with the highest quality of life in the world, according to the OECD better life index.
The gender gap
But we still have considerable work to do in many ways, including closing the gender gap in the workplace. The World Economic Forum has reported that in 2013 Australia continues to sit at 24th in closing this gap – just above Ecuador and Mozambique.
Australia still has only 17.6% representation of women on ASX 200 boards (as of 14 February 2014), and almost a quarter of boards of the ASX 200 still do not have any females at all.
Women working in science remain hugely underrepresented in leadership roles and some areas of physics and engineering have as little as 5% female participation.
The Australian Businesswomen’s Network says that women are starting small businesses at twice the rate of men. Despite this, a US study has found that female-owned companies are less likely to attract private investment compared to male-owned companies.
The recipe for success
If the nexus of women, science and business is the recipe for success in innovation, then how do women, science and business meet?
Equity, diversity and the lost opportunity of not capturing the full human potential are important arguments for having more women involved in science, technology and business.
But I have a new reason. As the traditional “social organisers” women bring a lot to the table. Business and science success is all about relationships and networking. You have to meet to do business.
Take the science world as an example. On average it takes about 20 years for a discovery to develop into a product. This has been an international rule of thumb. Everyone wants this to happen faster.
When you look at the reason for the delay, it is often when the development gets caught up in what is often called the “valley of death” or a black hole in the commercialisation process which can add years to transitioning time. Translating a discovery in the science lab to the engineering and development, then finally securing industry adoption can be a tortuous process.
What women can do
Women can offer a great deal in making that link as years of social conditioning means that it comes naturally to us.
Could the gender gap be a factor holding back the transition of science to industry, leading to missed opportunities? The diversity that women bring as scientists, technologists, engineers and nascent entrepreneurs might be the answer.
If women’s participation is a demonstrated element for business success and innovation is the essential ingredient for businesses to flourish, then why have we not embraced the opportunity to boost the role of women in science and business? Perhaps if we did we would witness greater translation of research to industry and our economic success would grow even more.
So at the end of a year thinking about what needs to change if we are to grow our economic and social prosperity, I think that increasing the participation of women in science, technology and business (big and small) is critical if Australia is to continue to have world leading quality of life, close the gender gap and have internationally competitive businesses.
Economic and social prosperity depends on change. This is one change we need to make now.

As many spend big this Valentine’s Day on roses, chocolates and novelty balloons – $791.4 million is expected to be spent nationally – we think that love is all you need. Over the past few months, we’ve had a summer romance-of-sorts with some of Australia’s brightest young minds. We’re talking about our vacation scholarship program, where about 200 undergraduate students spend their summer working on research projects across the country, from searching for black holes with our Parkes radio telescope to helping develop CO2 absorbent polymers.
This week, a group of our summer students got together for our annual Big Day In at the University of New South Wales, where they presented about their summer research. The student who took out the top presentation prize, Fletcher Talbot, worked on a gesture recognition system for the Museum Robot, or “M-Bot”, which roams the galleries of the National Museum of Australia. Fletcher created 40 custom hand gestures the M-Bot can detect.
The students also took the opportunity to declare their love for science. “I love Science because it’s a way of understanding the world,” and “I love Science because it’s really innovative, it’s always changing and it’s really dynamic.” Check out the video below.
Why do you love science? Let us know in the comments.
And happy Valentine’s Day.
It’s 1984. Shoulder pads, Walkmans and Macs were all the rage… and so were the Sci-Five. Well, at least in ‘science circles’ they were, as they battled it out for the BHP Science Prize.
They were our answer to a superhero gang, in that adorable-geeky kind of way. There was Geraldine who discovered a new species of goanna, and casually kept a two-metre pregnant python in her room. Then there was Tim who spent his life intimately studying wild duck behaviour, and Lindy who experimented with the effects of common drugs on mice. Darren was a budding physicist who came up with his own explanation for the “red-shift” of distant galaxies, and Robert designed a computer-based system for tracking boomerangs.
Here they are in action.
Back then the BHP Billiton Science and Engineering Awards were Australia’s most prestigious school science awards – and not much has changed today. The Awards recognise the innovation and creativity of our youngest and brightest sparks.
Now in their 33rd year, the entries are just as inspiring as those of the Sci-Five. Here are just a few.
The force is strong with Swirlesque
Imagine if you could turn on a light or play a DVD with the wave of your hand. Jake Coppinger’s Swirlesque glove lets you do just that.
It detects hand gestures, allowing us to control a range of devices like smartphones, computers, televisions and lightbulbs with the simple flick of a wrist.
To use Swirlesque you simply put the glove on, launch the app on a smartphone and press a button to connect via Bluetooth to the phone. The buttons in the Android app control the operation mode, which selects what gestures are assigned to.
Check it out in action.
On yer bamboo bike
Over 100 million bicycles are manufactured worldwide each year – that’s about twice the number of motor vehicles. They only use 2 per cent as much energy as cars per passenger-kilometer, but they are typically made from expensive, heavy metals like steel.
Ben Beagley wants to change this. Using the spare bamboo in his garage, he designed and constructed an organic, lightweight bamboo bike.
This is a much cheaper alternative to the traditional bike that uses the strength and flexibility of bamboo to replace heavy, industrial metal components.
Saving our troubled waters
When you live in the world’s driest inhabitable continent, it’s important that clean rainwater goes into our drainage systems without picking up pollutants like litter, chemicals and sediments.
Liam Grieve has looked at whether wetland plants could be effective at removing these nutrients from waterways, leading to a cleaner, healthier environment.
He set up experiments running nutrient-enriched water through three simulated wetland environments, and discovered the plants could effectively filter nutrients from the water.
To infinity and beyond
The space race might be well and truly over, but that’s not stopping Jack Allison. Combining his love of electronics and physics, he has investigated a new way to revolutionise space exploration.
Jack has designed and created an enhancement to help improve the performance of rail guns – also known as electrically powered projectile launchers – to demonstrate their potential for launching spacecraft into orbit.
He built a test rig and light-gate to measure the effect of this enhancement at different voltages, and looked at how the projectile responded magnetically when fired.
You can hear their full stories and more in the video below.
The winners will be announced at Melbourne’s ZINC on Tuesday 4 February from 11am AEDT. Head to BHP Billiton Science and Engineering Awards for more information.

Today marks the start of Dementia Awareness Week 2013, a national campaign to raise the profile of the many different forms of dementia, from Alzheimer’s to Parkinson’s disease.
More than 300,000 Aussies are estimated to be living with dementia – a figure which is set to almost triple by 2050. So how can we help lower our risk in the future?
Experts from Alzheimer’s Australia say we need to understand the connection between our physical health and our brain health. As we get older, it’s important that we take care of both our bodies and our brains.
Serious chronic illnesses like heart disease, stroke and diabetes, plus risk factors including depression, obesity and sleep are all associated with cognitive decline. If left unchecked, these conditions can increase our risk of developing a range of debilitating diseases including dementia.
So while there may not be a cure, we can help reduce our risk of dementia by maximising our brain health and managing our blood sugar, cholesterol levels, blood pressure and body weight.
Learn more about our work in the early detection of Alzheimer’s disease – the most common form of dementia.
Dementia Awareness Week runs from 16 to 22 September. Head to Alzheimer’s Australia for more information.

It’s not often we get to dress up and hit the red carpet, so when it happens we like to brag about it.
Last night we took to the Sydney Opera House to celebrate the 19th annual Deadlys. These prestigious awards recognise the achievements of Aboriginal and Torres Strait Islander people across a range of fields in our community.
While it was a nice excuse to rub shoulders with superstar Jessica Mauboy and photobomb RedFoo from LMFAO, that’s not why we were there.
This year a new award was added to the Deadlys – the inaugural Deadly Award for Indigenous Scientist or Science Project of the Year – and we were chuffed to be sponsoring it. The award recognises the significant contributions made by Indigenous people working in science roles or science projects.
Nominations were received from members of the public and five finalists were selected by a panel of deadly experts.
And the winner is: Gerry Turpin.
Gerry is an ethnobotanist at the Australian Tropical Herbarium in Cairns. He is working with our researchers and a range of other organisations to develop an Indigenous driven tropical ethnobotanical centre, known as TIEC.
The TIEC is the first of its kind in Australia and will help Traditional Owners in tropical Queensland apply their Indigenous environmental knowledge for cultural use on-country.
A big congratulations to Gerry and all of this year’s winners.
