Four researchers from the University of Sydney, the University of Wollongong and the University of Auckland were announced as the 2016 L’Oréal-UNESCO For Women in Science fellowships at a ceremony held in Melbourne on Tuesday.

Early-career veterinary scientists Dr Camilla Whittington and Dr Angela Crean joined chemists Dr Jenny Fisher and Dr Erin Leitao to receive $25,000 each towards a one-year project.

According to L’Oréal, the Women in Science fellowships were established to “support and recognise accomplished women researchers, encourage more young women to enter the profession and to assist them as they progress their careers”. The fellowships began in 1998, and have recognised over 2,000 women around the world since then.

From the University of Sydney:

“Both Dr Whittington and Dr Crean are early career researchers in the Faculty of Veterinary Science, working in the area of reproduction; both are in research positions funded through the Mabs Melville bequest in excess of $7.2m – one of the biggest gifts ever received by Veterinary Science.

Dr Crean’s initial research, using the sea squirt as a model organism, showed males can adjust their sperm quality and quantity in response to a perceived risk that their sperm will have to compete against another male’s sperm to fertilise an egg. The sperm quality also had adaptive consequences for both fertilisation and offspring survival.

Similar work using the neriid fly showed sperm quality could be adjusted by the father’s diet and social environment.

The L’Oréal-UNESCO For Women in Science Fellowship will allow Crean to conduct a proof-of-concept study supporting her transition from pure evolutionary research to practical applications in human reproductive health and medicine.

Dr Whittington, who last year was one of five University of Sydney researchers who won a 2015 NSW Young Tall Poppy Science Award, is using cutting‐edge techniques to identify pregnancy genes – the instructions in an animal’s DNA causing them to have a live baby rather than laying an egg.

‘Pregnant lizards, fish and mammals face complex challenges, like having to provide nutrients to their embryos and protect them from disease,’ Whittington says.

‘My research suggests that these distantly related animals can use similar genetic instructions to manage pregnancy and produce healthy babies.’

Whittington’s fellowship will allow her to investigate how the complex placenta has evolved independently in mammals, lizards, and sharks to transport large quantities of nutrients to the fetus.”

From the University of Wollongong:

Dr Fisher’s research into compounds that contribute to climate change and air pollution

“Dr Jenny Fisher from UOW’s Centre for Atmospheric Chemistry studies how different emissions interact with one another.

‘When I was little, I was intrigued by outer space and I knew I wanted to work for NASA. As my career progressed I felt that understanding my own planet was more important to me, so I made the change to researching the chemistry of our atmosphere,’ Fisher says.

Through the financial support provided by the L’Oréal-UNESCO For Women in Science Fellowship, Dr Fisher plans to develop an Australian atmospheric chemistry model, similar to those already successfully used in North America and Europe. Australia provides a unique globally-relevant lens for examining these processes due to the nation’s much lower presence of nitrogen oxides, pollutants that mainly come from human activities like driving cars and burning coal in power plants.

As stricter emission controls are enforced globally, the level of nitrogen oxides elsewhere in the world are predicted to decrease and Australia serves as a window to the expected future pollution outcomes.

The information provided from the model Dr Fisher works on will assist in predicting pollution amounts and their responses to future change. Australia’s much lower nitrogen oxide levels means this atmospheric model will also provide a novel insight into the pre-industrial atmosphere.

Currently, Dr Fisher can only investigate the Australian atmosphere by looking at large areas (~5 million hectares); however with the funding she will work on a more accurate ‘nested’ model, which can show what is occurring within an area more than 60 times smaller. This will enable her to increase the complexity of her atmospheric chemistry research and findings.

‘Winning the fellowship means I will finally be able to apply tools I have used in other global environments to problems that are specific to Australia. This work will help advance scientific understanding of the atmosphere on a global scale — while also providing new insight into what affects our local air quality,’ she says.

Dr Fisher’s work highlights her passion for communities to understand the impact we have on the environment. Her work in unlocking information about the chemistry of our atmosphere will improve our ability to make informed decisions in order to live in a sustainable way.”

Smashing the glass ceiling

“Science Meets Business” – this is a beautiful thing. It does not get better than that for me, having trained as a scientist and worked for more than 30 years in business, including the past 27 years with Dow, one of the world’s leading science and technology companies.  At Dow we are proud of our mission to combine chemistry, physics and biology to create what is essential for human progress. As our ever growing population faces pressing challenges, we believe that innovation will be the key to addressing the needs of the future.

Implicit in this vision is that graduates in Science, Technology, Engineering and Mathematics (STEM) are readily available to drive innovation and progress humanity and, just as importantly, that the graduate pool reflects the diversity of our society in all its dimensions.

Over recent years, there has been an increasing recognition of the imbalance of women in STEM.  This has culminated in an impressive $13 million of the National Innovation and Science Agenda (NISA) funding being earmarked to support women in STEM careers including support for SAGE, Australia’s Science and Gender Equity initiative to promote gender equity in STEM.

Changing corporate culture

There is a real need for this concerted effort to address gender inequity. According to the Chief Scientist’s March 2016 report, women make up only 16% of Australia’s STEM Workforce.

The good news is that in recent years, a lot has been done to address the gender inequality issues.  We have a strong combination of social awareness, government policy and financial investment, corporate and business buy-in and social consciousness of the issue.

I have recently met a number of female board directors who have openly acknowledged that their appointment is due to the Victorian governments spilling of agency boards and establishing a 50% gender quota requirement. This is one example of real and substantial change.

Across the globe, Dow has over 1,600 employee volunteers, known as STEM Ambassadors, who are helping to bring STEM subjects to life in the classroom, and serving as role models of a diverse STEM workforce.

In partnership with the Women in Business Summit hosted by the American Chamber of Commerce in Japan (ACCJ), Dow has also taken a leadership role to improve STEM career development opportunities for women.  We are progressing slowly, but steadily, with women constituting nearly 60% of new Australian and New Zealand hires at Dow in 2016.

With the $13 million NISA investment and the changing corporate culture, now is the perfect opportunity for young women to seek and develop a career in STEM.

Innovation in general will be the driving force of commercial success, economic growth and national development. A large part of this will come from R&D and innovation in STEM fields.

If the majority of future jobs are yet to be imagined, then women in particular are in a perfect position to seize the opportunity of creating these positions.

The management glass ceiling might exist today, but if the jobs are yet to be invented, then then we have a chance of shattering that ceiling in the future.

Supercomputer empowers scientists

Creating commercial drugs these days seems to require more time at the keyboard than in the lab as these drugs can be designed on a computer long before any chemicals are combined.

Computer-based simulations test the design created by the theoretical chemist and quickly indicate any potential problems or enhancements.

This process generates data, and lots of it. So in order to provide University of Western Australia (UWA) chemistry researchers with the power to perform these big data simulations the university built its own supercomputer, Pople.

Dr Amir Karton, head of UWA’s computational chemistry lab says the supercomputer is named after Sir John Pople who was one of the pioneers of computational chemistry for which he won a Nobel Prize in 1998.

“We model very large systems ranging from enzymes to nano materials to design proteins, drugs and catalysts, using multi-scale theoretical procedures, and Pople was designed for such simulations,” Karton says.

“These simulations will tell you how other drugs will interact with your design and what modifications you will need to do to the drug to make it more effective.”

Pople was designed by UWA and while it is small compared to Magnus at the Pawsey Supercomputing Centre it gives the researchers exactly what they want.

That being a multi-core processor, a large and very fast local disk as well as 512 GB of memory in which to run the simulations.

Magnus’ power equivalent to 6 million iPads

While Magnus has nearly 36,000 processors—processing power equivalent to six million iPads running at once—Pople has just 2316 processors.

But, Magnus was designed with large computational projects like the Square Kilometre Array in mind whereas Pople provides such services to individual users.

Dr Dean Taylor, the faculty’s systems administrator says the total amount of memory available to Pople amounts to 7.8 TB, and the total amount of disk space is 153 TB, which could fill almost two thousand 80 GB Classic iPods.

By comparison a top-of-the-range gaming PC might have four processors, 16 GB of memory and a 2 TB disk drive.

A large portion of the Intel Xeon processors (1896 cores) were donated by Perth-based geoscience company DownUnder GeoSolutions.

DownUnder GeoSolutions’ managing director Dr Matthew Lamont says it is the company’s way of investing in the future.

Pople will also assist physics and biology research involving the nature of gravitational waves and the combustion processes that generate compounds important for seed germination.
