The election collection: tracking trends on Twitter

A wordcloud from Vizie, which tracks, integrates and visualises content across social media in real time.

Vizie tracks, integrates and visualises content across social media in real time.

With over 500 million tweets flying around the Twitterverse every day – ranging from the excruciatingly banal to the discerning and insightful – this micro-blogging platform can provide an immediate and detailed insight into public sentiment and community conversations.

It is this vast amount of shared information that makes Twitter a treasure trove of data for future historians. However due to the instant and fleeting nature of the online world, it’s important to record these conversations as they happen so that our history is preserved.

That’s why we’re working with the State Library of NSW to help capture digital conversations on hot topics relevant to the state. And at the moment, there’s nothing on people’s minds (and keyboards) more than the upcoming state election.

As NSW residents prepare to head to the polls this weekend, the library is collating and archiving publicly available Twitter activity as part of its efforts to capture and document events of historical significance. They are collecting public conversations about the economy, big and small personalities, fundraising, the media and a broad range of local and global issues.

This is all possible thanks to our social media monitoring software called Vizie.

Vizie is a web based platform that tracks, integrates and visualises content across social media in real time. It also allows users to collect swathes of tweets based on a particular hashtag or topic so that they are preserved for the future.

For the NSW election, the library is capturing the tweets of the majority of candidates running – that’s over 200 Twitter handles. It’s also collecting discussions about parties and interest groups and tracking topical issue such as #csg and #polesandwires.

So far almost 400,000 election-based tweets have been captured and preserved.

This digital record will add to the library’s extensive election archive which dates back to the 1840s and 50s. This is full of artefacts such as newspaper clippings, electoral flyers and how to vote cards which show how political campaigns, the act of running for candidacy and voting has changed over the decades.

Keeping up with the Joneses: Who has the coolest house in the neighbourhood?

Ever wondered how hot your home gets in summer or how cold it is in winter? Think solar is a good idea but not quite sure if it would work on your roof? Wondering if it’s worth investing in a rainwater tank?

Now with a new interactive tool we helped develop called My Climate, residents of Melbourne’s City of Port Phillip can do their own internet-sleuthing to answer these questions. What’s more, this could kick-start a trend that would see residents around the country taking more responsibility for these types of decisions.

My Climate uses thermal mapping taken from aerial flyovers and seven temporary weather stations to show land surface temperatures, winter heat loss, rainfall and the solar potential of all buildings in the region.

My Climate can show heat loss during Winter.

Working with the City of Port Phillip and Monash University, we originally developed My Climate to inform urban planning decisions. It didn’t take long to realise how useful the data would be to the whole community.

“With this data you can calculate the most appropriate solar system for your home, where it would best be located and how much it could potentially save you in electricity costs and Co2 emissions. You can also measure rainfall and calculate the cost of improving your ceiling insulation,” Port Phillip Mayor Amanda Stevens says.

“If thermal imaging shows your neighbour’s home is cooler than yours, it may mean they have better insulation, or cool air from their air-conditioner is leaking outside the home.

“This easy-to-use tool has the potential to add real value to people’s homes and on a larger scale can help tackle the impacts of climate change.”

Dr Mahesh Prakash and his group from our Digital productivity Flagship helped develop the analytics and software component of the interactive tool. He says his team is now looking to expand My Climate to include other layers of information such as natural hazard hotspots and optimum tree coverage. He would also like to see it rolled out to other Councils.

How our supercomputers are helping fight heart rhythm disease

Dr Adam Hill and Professor Jamie Vendenberg are driving this groundbreaking research.

Heart rhythm disease is a life-threatening, electrical disorder that stops the heart from pumping blood effectively. It is a lethal condition that is responsible for around 12 per cent of Australian deaths each year.

In order to open the door to better diagnosis and treatment for heart rhythm disease, we’ve been working with the Victor Chang Cardiac Research Institute to develop our very own ‘virtual heart’. What’s more, we’ve done this using the same technology that drives your favourite computer games.

Impressively, when we ran a simulation through the virtual heart, it was able to model hundreds of thousands of different heart beats. This then allowed scientists to screen all of those heart beats, and search for abnormalities.

According to the Victor Chang Institute’s Dr Adam Hill who led the research, this has taken us a step closer to understanding rhythm disturbances in our most vital muscle.

“This research is hugely exciting! We were able to identify why some patients have abnormal ECG signals, and how a person’s genetic background can affect the severity of their disease,” he says.

Analysis on this scale has simply never been possible before. The simulation took just ten days, thanks to the computational grunt of CSIRO’s Bragg supercomputer cluster, which combines traditional CPUs with more powerful graphics processing units or GPUs.

GPUs have typically been used to render complex graphics in computer games. However they can also be used to accelerate scientific computing by multi-tasking on hundreds of computing cores.

By comparison, if you were to try to do the same simulation using a standard desktop PC, it would take 21 years to get the job done.

Powerful and eco-friendly? This is one super computer worth Bragging about.

Adam hopes the new technology will help doctors read ECGs more accurately, which will mean faster, more accurate diagnosis of heart rhythm disease. By understanding why the same disorder affects people differently, the right treatment can be given to the right patients.

Scientists at the Victor Chang Institute are now using these discoveries to develop automatic computerised tools for diagnosing heart rhythm disorders.

The science to being crowned king of the crackers

With the festive season in full swing, many of us will soon find ourselves sitting around a dinner table, tugging on a Christmas cracker then poring over the goodies found within.

Traditionally, cracker etiquette dictates that the person left holding the larger portion is dubbed the cracker king (with flimsy paper crown to prove it).

However, have you ever wondered what ‘cracker strategy’ you should employ to increase your chance of securing the win and looking like one of the Wise Men?

Naturally, our researchers Emma Huang and David Clifford along with their equally-festive colleague from the University of Queensland Kim-Anh le Cao, were wondering the same thing. So they turned to science to find out.

Firstly, they got cracking on identifying three cracking cracker-pulling techniques:

  1. The ‘angle’ strategy: A firm two handed grip, tilting the cracker between 20 and 55 degrees downwards, and applying a steady force with no torque
  2. The ‘passive aggressive’ strategy: a firm two handed grip at no angle, no pulling at all, and letting the other person do the work
  3. The ‘control’ strategy: typical of Christmas parties around the world, where both participants pull at no particular angle, but roughly parallel to the floor

In this festive study, volunteers were randomly paired, employing different strategies multiple times in order to leave us with robust data about the validity of each technique.

So, what were the results?

If you’re an angler, we’ve got bad news. With just a 40 per cent win rate, this technique isn’t likely to secure your spot as cracker king anytime soon. The traditional ‘control approach’ produced the results closest to random chance, resulting in a win 53 per cent of the time.

For those saying bah-humbug to the passive aggressive approach, you might want to rethink things. With an impressive 92 per cent success rate, it turns out the key to securing the win is to let your partner do all the hard work.

As our researchers describe in their study, the passivity of this approach could have important implications for future Christmas parties. Aside from the obvious reduction in cracker-related injuries, the strategy has another major benefit – it is easy to employ with subtlety, unlike strategies involving an angle, which must surely arouse suspicions in your pulling partner.

While we wish you well on your cracker journey, we’ll leave you with a word of caution – while the ‘do nothing’ approach does have a high success rate, it only works if you’re the only one who knows about it.  If both you and your partner employ the same strategy, the party could stretch on forever, resulting in a burnt dinner and no paper crown for you.

The eyes have it: Is this our next Australian of the Year?

 

Dr Yogi Kanagasingam

State finalist in the Australian of of Year awards, Dr Yogi Kanagasingam

Meet Yogi Kanagasingam. Yogi works at our Australian e-Health Research Centre and his vision is to change the way eye care is delivered around the world to prevent needless blindness.

A ‘serial inventor’, Yogi has developed a number of low-cost diagnostic technologies that are used to take images of our eyes.  These devices are helping in the early detection of serious conditions, ranging from those that directly threaten sight, through to stroke and Alzheimer’s Disease.

By focusing on affordable, mobile solutions, he is bringing quality eye care to thousands of patients who might otherwise have gone without.

Recognising this passion and dedication, Yogi has been named as a WA finalist in the 2015 Australian of the Year Awards. Here are just some of the sight-saving (and often life-saving) projects he’s working on:

Saving sight in remote communities

Regular eye tests are important. They can be used to pick up many diseases including diabetic retinopathy – one of the leading causes of irreversible blindness in Australian adults.

However due to the remoteness of some Australian communities, it can be very difficult for people to access this type of specialist care.

That’s why we’ve been working with our partners in Western Australia (Gold Fields and Great Southern) and Queensland (Torres Strait Islands) to set up remote eye screening – giving hundreds of people access to eye testing services.

This is possible thanks to technology Yogi has developed called Remote-I.

Using Remote-I, local clinicians are able to conduct routine retinal screenings, often as part of scheduled health clinic visits. The system then sends hi-res retinal images to a city-based specialist ophthalmologist via satellite broadband – allowing them to accurately diagnose and refer patients who need immediate treatment.

Retinal images and electronic patient files are sent to city-based ophthamologists.

 A global vision for eye care

Now Yogi and his team are taking Remote-I to the world. For the past year, they’ve been working with the Zhongshan Ophthalmic Centre in China’s Guangdong Province to introduce the technology throughout a network of ten hospitals.

With a population of over 100 million people in Guangdong, local health professionals are now using the technology to screen up to 1000 patients per week. That’s a lot of eye tests.

As well as giving patients access to specialist care, this project is also providing the research team with valuable data about blood vessel patterns in retinas. This will allow them to design algorithms that could be used to automatically detect particular eye diseases, aiding diagnosis in routine screenings.


Early detection of Alzheimer’s

Using curcumin (a compound in the spice turmeric), Yogi and his team have also developed a spice-infused eye test for Alzheimer’s disease.

Patients ingest the curcumin which binds to beta-amyloid plaques (the sticky proteins that indicate Alzheimer’s) showing up in retinal scans as bright spots which can be counted and measured.

Early results show the amount of plaque in the retina closely mirrors the amount in the brain. If confirmed, this could be the beginnings of an easy, non-invasive test for early detection of Alzheimer’s – maybe up to 20 years before cognitive symptoms appear.

We’re proud as punch of Yogi. As well as the groundbreaking work he is doing with us here at CSIRO, he is also giving back to the community in his personal time. Yogi is actively involved with local Rotary Clubs, including Freshwater Bay Rotary in WA where he helps promote regular eye screening for primary school children. This can make a big difference to students, as early detection of vision abnormalities can improve both academic and sports performances.

We wish Yogi all the best this Saturday when the WA Australian of the Year will be announced at Government House. WA’s winner will then join recipients from other States and Territories as finalists for the National Awards, to be announced on Australia Day 2015.

Mission accomplished: lost bushwalker saved by flying robots

Outback_Joe_mannequinpicture-108

At long last, Outback Joe has been found.

By Emily Lehmann

Flying robot enthusiasts can breathe a deep sigh of relief, because Outback Joe has finally been saved after spending eight years lost in the bush.

This week, sixteen teams from around the world competed in the search and rescue mission to save our beloved Akubra-clad mannequin pal, who has year after year, been strategically placed in the Queensland outback as part of the Unmanned Aerial Vehicle (UAV) Challenge.

After eight years running, this was the first time that a team – not just one, but four– successfully delivered the emergency package to save Outback Joe, with the top team taking home a grand prize of $50 000.

Each team was tasked with developing their own custom-made UAV (a.k.a flying robot or drone) and navigating it through a course to first locate Outback Joe, and then secondly deliver him a life-saving bottle of water.

The competition brings some of the latest international aerial robotics technology and puts it to the test to highlight its value for use in search and rescue efforts.

These flying machines can cruise at various speeds – some are just like helicopters – and can mostly fly for 40 to 60 minutes at a time. They rely on modern computers and sensors, such as GPS, to figure out where they need to go in order to perform tasks that the operator has asked it to do.

The clever minds behind the winning ‘bot are from CanberraUAV and managed to score the most points out those that completed the challenge – two other Australian teams and one from the United States.

The UAV Challenge also involves a delivery challenge for high school teams, taking place earlier in the week. Students build their flying robots from scratch, designing and developing the software and hardware needed for their own rescue mission for Outback Joe.

This year’s winner was the all-girl DareDivas team from Mueller College at Redcliffe with a $5 000 prize.

We run the UAV Challenge annually in partnership with the Queensland University of Technology.

Bees backpacking in Brazil

Bee with a backpack…of the sensor variety.

By Emma Pyers

How do bees in the Amazon jungle compare to those in Tasmania? They get up earlier, for a start.

Paulo de Souza and his team have been tracking bees in the two regions using tiny backpack sensors as part of our Swarm Sensing Project to gather biological and ecological data to improve honey bee health.

The tiny backpacks are just a quarter of a centimetre square and are fitted to the back of the bees.

“We have already attached the micro-sensors to the backs of thousands of bees in Tasmania and the Amazon and we’re using the same surveillance technologies to monitor what each bee is doing, giving us a new view on bees and how they interact with their environment,” Paulo said.

“Once we have captured this information, we’ll be able to model it. This will help us understand how to manage our landscapes in order to benefit insects like bees, as they play such a key role in our lives. For example, one third of the food we eat relies on bees for pollination, that’s a pretty generous free service these humble insects provide us!”

Early modelling has shown one notable difference between the bees in Tasmania and those in the Amazon; Amazon bees are up and about very early in the morning while Tassie bees prefer to wait until the day warms up before they leave the hive.

But finding out what time bees get out of bed is only a tiny part of what the research can show us. For example the research will also look at the impacts of agricultural pesticides on honey bees by monitoring insects that feed at sites with trace amounts of commonly used chemicals.


A global buzz in micro sensing

We’re working with the Vale Institute of Technology in Rio de Janeiro, Brazil, on micro-sensory technology and systems (read  more about what Vale is up to here).

Working with researchers across the globe has its unique challenges as well as its rewards, and it’s the physical challenges that have been the most interesting.

“As the Africanised honey bees were very aggressive, the hive was placed in an isolated area away from housing and domestic animals – and isolation meant working in densely vegetated areas,” Paulo explained.  “We had to clear a path to the hive and we wore fully protective bee clothing which was tough given the extreme humidity and heat.”

The Brazilian media got a taste of what it was like to work in these conditions, when they suited up to interview Paulo and our colleagues from the Vale Institute of Technology about their work

The collapse in global populations

Bee health is important globally however, honey bee populations around the world are in danger.

Colony Collapse Disorder (CCD) – a phenomenon in which worker bees from a colony abruptly disappear – and Varroa mite are two major problems facing bee populations globally. While these two problems haven’t appeared in Australia, there is a very real risk.  And what happens if it does? Catastrophe!

Check out this video where Peter Norris, Tasmanian beekeeper, describes his first hand experience with CCD while working in the United Kingdom.

So it’s a good thing our scientists, and their colleagues in Tassie and Brazil, are on the case.

To learn more about how we’re trying to save honey bees around the world tune into ABC Catalyst at 8pm tonight.

CSIRO’s Swarm Sensing Project is a partnership with the University of Tasmania and receives funding from Vale, a Global mining company.
