The atmosphere in the Braggs has never been more exciting than it was on Thursday 6 September 2018. It was the first #IPASOpenDay with attendance of more than 200 people from the general public, university stakeholders, STEM students and industry partners. The day kicked off with an hour of presentations by six IPAS team leaders who shed light on the culture and ground breaking research within IPAS. The “loud and clear” message for school students was about the tremendous opportunities in Defence, Space and Start-ups in SA.
The event offered a unique opportunity for all visitors to experience the state of the art facilities at IPAS up close. All IPAS-related research labs in the Braggs, MLS and Physics buildings were open for more than two hours and it was rewarding to see wide-eyed visitors coming out chatting excitedly about their experiences. With so much to offer, it was our pleasure to see such a diversity of people at IPAS especially the STEM students who had so much fun and gained so much from the experience. The IPAS demonstrations table with the Interferometer and the Radio Laser was always full of people with interesting questions. The visitors even got to experience a fluorescent chocolate fondue, and see how to measure radiation through a banana smoothie…
The day was a huge success and a credit to those staff who put together such a fun and inspiring event. Next year will be even bigger and better. Given the benefits of explaining to the community what we really do at the University, this might be something to be considered more broadly across the campus. The philosophy of opening the labs to all and being transparent about our activities can be very powerful.
If you are interested in exploring potential synergies and being part of next year’s event, please contact Elodie Janvier, IPAS Strategic Research Development Manager.
Published this week in the prestigious Physical Review Letters journal, IPAS researchers have demonstrated a record performance in the generation of metastable krypton by using a two photon excitation technique. This is set to bring extreme value as a source for metastable atoms for laser cooling and trapping applications, in particular for atom trap trace analysis (ATTA).
Here, they show an efficiency of up to 2% per pulse; a great step towards achieving the holy grail of 10% that would allow the dating of deep ice core samples. This has the potential to revolutionise the ice core research field by addressing one of its key unmet challenge of extending the existing 800,000 years dating record back in time to 1.5 million years and help unravel many mysteries that are still puzzling geologists today.

IPAS researchers Prof Andrew Abell and A/Prof Tara Pukala are part of a University of Adelaide research team who will lead the Agricultural Product Development Research Consortium to increase the agriculture value and turn it into new products.
The Consortium, led by Prof Vincent Bulone, has been granted $4M over four years by the State Government through its Research Consortia Program. It will bring together a total of 18 partners to develop high-value products from agricultural waste: nine South Australian-based companies from the agriculture and food sector, and another nine national and international academic institutions and industry partners. The support coming from the partners brings the total value of the consortium to $10.9M.
The Consortium will build on the work of Adelaide Glycomics, a carbohydrate analytical facility at the Waite campus, and make use of other, complementary analytical activities provided by the Adelaide Proteomics Centre at the University’s North Terrace campus. “This Consortium draws together a unique combination of research expertise, facilities, industry know-how and resources. It promises increased profitability and sustainability for our local agricultural and horticultural industries, and significant health and economic benefit for our whole state,” says University of Adelaide Deputy Vice Chancellor (Research) Professor Mike Brooks.
“The Consortium has already drawn the support of four international industry partners, which shows the incredible commercial potential to be developed.”

Unveiling of China-Australia Joint Laboratory for Fabrication of the special Optical fibres and biochemical Detection Innovation (CAFODI)
Building on two complementary areas of research excellence with strong industry relevance, IPAS and the Laser Institute (LI) of the Shandong Academy of Sciences (SDAS), the Joint Laboratory CAFODI (China-Australia Joint Laboratory for Fabrication of the special Optical fibres and biochemical Detection Innovation) was established in September 2017, and officially unveiled by Hon David Ridgway, South Australian Minister for Trade Tourism and Investment and VC Peter Rathjen of University of Adelaide in Jinan, Shandong, China, on 17th July 2018.
CAFODI aims to fabricate novel microstructured optical fibres and develop biochemical optical sensors, speeding up their translation in the global market as well as postgraduate education. The joint laboratory is led by Prof Heike Ebendorff-Heidepriem and Dr Yinlan Ruan in Adelaide and Director Zhongqing Jia and Dr Jiasheng Ni of Laser Institute, SDAS, in China. An initial commitment of AU$60K was made from the University of Adelaide in January, 2018 and the second investment from our partner is on the way and will focus on fabrication of the hollow core fibres and petrol sensors. We expect that establishment of CAFODI will largely contribute to increasing commercial opportunities for SA researchers and education institutions and demonstrate a shared commitment to solve industry problems through research and collaboration.

A new molecule designed by University of Adelaide researchers shows great promise for future treatment of many cancers.
The new molecule successfully targets a protein that plays a major role in the growth of most cancers. This protein target is called proliferating cell nuclear antigen (PCNA), otherwise known as the human sliding clamp.
“PCNA is required for DNA replication and is therefore essential for rapidly dividing cancer cells,” says project leader Dr John Bruning, Senior Research Fellow at the University’s Institute for Photonics and Advanced Sensing (IPAS).
“PCNA holds the machinery that copies DNA. The DNA slides through the centre of this donut-shaped protein where it is replicated.
“If we can inhibit the action of this protein, the cells can’t make DNA, so they can’t divide. This is really tackling cancer at ground zero. It’s stopping cell division and therefore tackling cancer at its most fundamental level.
“We also know that PCNA is ‘overexpressed’ – or makes too many copies – in 90% of all cancers. That means it is a potential target for inhibiting the growth of multiple cancers, not just a select few.
“And importantly, this protein seldom mutates which means that it is less likely to develop resistance against a drug inhibitor.”
The research, in collaboration with the University of Wollongong, has been published in Chemistry, A European Journal.
The multi-disciplinary team at IPAS designed a molecule that can interact with PCNA, offering a promising new strategy for the design of a PCNA inhibiting anti‐cancer treatment.
“In this study, we have taken a protein fragment that naturally interacts with PCNA and transformed it using smart chemistry into a drug-like molecule,” says lead author Dr Kate Wegener, Ramsay Postdoctoral Research Fellow in the University of Adelaide’s School of Biological Sciences.
“We’ve changed its chemistry to protect it from degrading like the natural protein, and so that it works better.”
The new molecule shows increased potency over other PCNA inhibitors, and is likely to show less side-effects.
“Because of the special approach we have used in turning a natural protein into a drug-like molecule, it fixes to PCNA more readily and its action is specific to this protein,” says Dr Bruning.
“This is a first. It’s the first in this type of inhibitor and it will pave the way for a new class of drugs inhibiting the proliferation of cancerous cells.”
