IVF grant success

26 April 2017:

CNBP Chief Investigator, A/Prof Jeremy Thompson has received $7000 in travel support from the Global Connections Fund Priming Grants initiative.

The grant will fund travel to the USA to visit cattle IVF units with the aim of learning how they have made a successful business of in vitro produced embryos, and where it applies best in their (beef) breeding and genetic selection operations.

While there, A/Prof Thompson will be sharing knowledge and experiences and seeing if there are potential collaborative opportunities.

Social media for research engagement

21 April 2017:

CNBP’s Dr Hannah Brown (pictured), together with Prof Ben Mol, the University of Adelaide and Melinda Cruz, CEO and Founder of Miracle Babies Foundation, believe that social media interaction and scientific activity should go hand-in-hand.

They argue that increased social engagement by scientists with collaborators, the media, governing and funding bodies, government and consumers underlies research success.

Check out their latest written piece, ‘Social media is essential for research engagement‘ in BJOG, an International Journal of Obstetrics and Gynaecology.

New sensing methods for embryos

A/Prof Jeremy Thompson, CNBP Chief Investigator, has given an invited talk at  the 7th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2017) in Kuala Lumpur, Malaysia, on the 2nd April 2017.

The Congress is the largest clinical reproductive medicine meeting in the Asia-Pacific region with A/Prof Thompson’s talk titled, “New sensing methods for embryos.”

 

New PhD candidate Yuan Qi Yeoh

30 March 2017:

CNBP welcomes its latest PhD candidate Yuan Qi Yeoh who is working on controlling the structure and activity of an antimicrobial peptide using an azobenzene photoswitch.

Supervised by CNBP Chief Investigator Prof Andrew Abell at the University of Adelaide, Yuan Qi will design and synthesise peptides that mimic Gramicidin S, incorporating azobenzene to turn antimicrobial activity on and off when desired.

Tested will be the effectiveness of the synthetic peptidomimetics by biological assays against S. aureus and E. coli – this recognising the structure-activity relationship of the synthetic peptidomimetics against bacteria.

Previously, Yuan Qi completed an Honours Degree at the University of Adelaide under the guidance of Prof Abell with her thesis titled, “Controlling the Conformation of a Modified Gramicidin S Cyclic Peptidomimetic with an Azobenzene Photoswitch.”

She has also participated in summer research (synthesising an azobenzene photoswitch) supervised by both Prof. Andrew Abell and CNBP Research Fellow Dr. Jingxian Yu.

Welcome to the CNBP team Yuan Qi!

 

Nanoscale sensor to spot disease

28 March 2017:

A new nanoscale sensor has been developed that can help detect cytokines – molecules that play a critical role in cellular response to infection, inflammation, trauma and disease.

Reported in the science journal ‘Nanoscale’, the sensor consists of a modified graphene quantum dot (or GQD) which has been designed by researchers at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP). It allows ultra-small amounts of cytokines to be identified in and around cells, with the work potentially opening up an exciting new avenue of biomedical research.

“Cytokines are molecules secreted by the cells of the immune system,” explains lead CNBP project scientist Guozhen Liu, Associate Professor at Macquarie University.

“The release of certain cytokines by the body is frequently symptomatic of a disease or health related issue, such as arthritis, inflammatory disorder or even cancer. Consequently, monitoring cytokine secretions at the cellular and sub-cellular level, has enormous value in our understanding of basic physiology and how the body is actually working.”

Traditionally, cytokine molecules have been extremely hard to measure and quantify.

“This has been due to their small size and their dynamic and transient nature,” says A/Prof Liu.

“What we’ve been able to do is to design and make a sensor that is so small that it can easily penetrate inside cells. Moreover, unlike other sensors it only responds when the cytokine is present. To this aim we have connected GQDs to cytokine sensing DNA molecules known as aptamers.”

Professor at Macquarie University, Ewa Goldys, Deputy Director at the Centre for Nanoscale BioPhotonics, also on the project team, noted that the detection of cytokines in body fluids, cells, tissues and organisms was attracting considerable attention in the biomedical research field. “Being able to track cytokine levels in real time opens new ways to monitor body physiology. This will ultimately lead to new diagnostic tools and new ways of treatment monitoring.”

Goldys believes that the innovative GQD sensing technology developed by the CNBP has potential widespread applications, due to the universal nature of the sensor design.

“We see these graphene quantum dot sensors as being excellent candidates for many other biomedical applications such as DNA and protein analysis, intracellular tracking as well as for monitoring of other cell secreted products in the body.”

Although still some years away from clinical study Goldys and Liu are both excited by the research. “Operating at the nanoscale we’re creating entirely new windows into the body and will gain valuable insights into the body, health, wellbeing and disease,” concludes Goldys.

CNBP engages with Shanxi Province

26 March 2017:

CNBP Director Prof Mark Hutchinson has showcased CNBP science to the Vice Governor of Shanxi Province together with his Heads of Departments (Agriculture, Science and Technology and Foreign Affairs) who were visiting the University of Adelaide and the South Australian Government on March 26th, 2017.

The visit, a result of the University of Adelaide and its seven year relationship with the Province, sees the University undertaking increasing work there, with both industry and Government, primarily in the areas of agriculture and functional food.

It is likely that CNBP products and the potential of the Centre will be further demonstrated in May, when  a delegation from South Australia will go to Shanxi Province to engage with industry.

Centre CI at Gordon Glycobiology conference

25 March 2017:

CNBP Chief Investigator Professor Nicki Packer was an invited chair of a session and leader of the Power Hour (gender equality workshop)  at the Gordon Glycobiology conference at Ventura, California 19-24 March, 2017.

As session Chair, Prof Packer led discussion on advances in omics, integrated omics, bioinformatics for glycobiology and the impact of altered glycosylation for human disorders.

The Power Hour was an informal session designed to help address the challenges women face in science and to support the professional growth of women by providing an open forum for discussion and mentoring.

Further conference information is accessible online.

 

CNBP talks to the pollies at SmP

24 March 2017:

A chance to talk science with Australian politicians and policy influencers was an opportunity seized by CNBP with Centre Investigator Prof Heike Ebendorff-Heidepriem and Centre Research Fellow Dr Andrew Care both in attendance at the annual ‘Science meets Parliament’ (SmP) event, Canberra, 21-22 March, 2017.

Established by Science and Technology Australia, SmP provides 200 scientists with a unique professional development opportunity to get a clear sense of the competing rationalities of science, politics and public policy. The two-day gathering also includes a day at Parliament House, where delegates get the chance to meet privately with parliamentarians.

As part of this activity, Prof Ebendorff-Heidepriem met with Senator Chris Back and Senator Chris Ketter, and also spoke with Shadow Minister of Defence, Richard Marles. In addition, she spoke with many researchers and entrepreneurs from both the University and industry sectors.

“Improving collaboration between the research community and industry was a hot topic in many of the discussions that I had”, said Heike. “Particularly in my meeting with Senator Chris Back. People were also extremely excited about our approach, in using fibres and light to create exciting new windows into the body.”

CNBP’s Dr Andrew Care met with Opposition Leader Bill Shorten’s advisor, discussing gender equality and early education for STEM and also touching on ECR opportunities and improving research and industry ties. He also met MP Adam Bandt, the Greens spokesperson for science.

“Overall it was an extremely rewarding experience,” says Andrew. “Attending SmP gave me the opportunity to explore the political process and to network with many other researchers from academia, industry, and governance. It was fantastic to see science and innovation so high on the government’s agenda.”

A full round up from both days of SmP can be found on the STA web site – Day 1 and Day 2.
