Fitting in a half day of outreach at McMeen Elementary School in Denver, Colorado, was a highlight for CNBP Research Fellow Lindsay Parker.

Spending time with a class of Year 5 students and their teacher, Lindsay led discussion about what scientists do, how research is conducted and answered a large number of science related queries.

Students were provided with the CNBP educational activity resource sheet and also given an overview of light based research currently being undertaken at the nanoscale.

“Spending time with kids and encouraging their interest in science and technology is a real buzz,” says Lindsay. “These kids were extremely inquisitive which is great.”

MQ Uni hosts Coolangatta school students

192_denitza_denkova_WP12 February 2016:

CNBP Research Fellow Denitza Denkova has helped host a school visit to Macquarie University’s Physics and Astronomy Department.

The Year 12 science students, from Kingscliff High School, South Coolangatta, were shown a number of experiments and videos relevant to their Higher School Certificate study.

Explained were principles encompassing particle and wavelength duality, as well as the significance of the recent announcement related to the discovery of gravitational waves – a major event in the world of physics.

Invited talks at University of Colorado Boulder

Ewa Goldys, CNBP Deputy Director and Lindsay Parker, CNBP Research Fellow were invited speakers at the University of Colorado Boulder.

Ewa and Lindsay, hosted by Profs Steven Meier and Linda Watkins from the Department of Psychology & Neuroscience, spoke about various activities and projects currently taking place across the CNBP. Also discussed were potential areas of research collaboration.

Summer scholarship students at Macquarie

lindsay_parker-low-rez-web110 February 2016:

Lindsay Parker, CNBP Research Fellow, supervised undergraduate student Tereza Lois-Palumbo and Masters student Ashish Shrestha during their 5 week summer scholarship program at Macquarie University.

Tereza and Ashish researched gene changes in multiple cell lines after exposure to LPS inflammation. They learned skills in cell culture, sample staining, microscopy, data analysis and data presentations during their short program.

Ashish will continue to be mentored by Lindsay throughout the year on CNBP related research projects related to ISH gene testing.

Vicky Staikopoulos begins PhD at CNBP

Vicky staikopoulos9 February 2016:

We’re happy to report that Vicky Staikopoulos has started her PhD study at the Centre for Nanoscale BioPhotonics at the University of Adelaide.

Vicky who has worked closely with CNBP researchers in recent years as an assistant researcher and laboratory manager, is looking into the role of NO (nitric oxide) and HNO (nitroxyl) in neuropathic and inflammatory pain mechanisms within the CNS and periphery, as well as their involvement in morphine tolerance.

Using novel sensing tools developed by CNBP chemists (Michelle Zhang and Sabrina Heng) and CNBP physicist (Martin Ploschner), Vicky will be supervised by CNBP Director Prof. Mark Hutchinson and Dr. Elizabeth Beckett, Senior Lecturer in the School of Medical Sciences at the University of Adelaide.

Vicky hopes to identify novel targets for drug development in pain management and improve the effectiveness of current pain medication by increasing the understanding of drug tolerance using unique, CNBP generated, sensing and imaging tools for the first time.

New technique for fabricating micro-optical sensors

Stephen Warren-Smith9 February 2016:

Associate Investigator Dr Stephen Warren-Smith at the Institute of Photonic Technology (Jena, Germany) has just published work on a new fabrication technique for creating micro-optical sensors in CNBP optical fibres.

Abstract:

We demonstrate the use of focused ion beam milling to machine optical structures directly into the core of microstructured optical fibers. The particular fiber used was exposed-core microstructured optical fiber, which allowed direct access to the optically guiding core. Two different designs of Fabry-Perot cavity were fabricated and optically characterized. The first cavity was formed by completely removing a section of the fiber core, while the second cavity consisted of a shallow slot milled into the core, leaving the majority of the core intact. This work highlights the possibility of machining complex optical devices directly onto the core of microstructured optical fibers using focused ion beam milling for applications including environmental, chemical, and biological sensing.

CNBP researchers at ICONN 2016

Peipei-Jia7 February 2016:

CNBP researchers Peipei Jia (pictured), Philipp Reineck, Ivan Maksymov, Sabrina Heng and Daniel Stubing all attended the International Conference on Nanoscience and Nanotechnology (ICONN), in Canberra (7-11 February 2016).

Peipei Jia, CNBP Research Fellow, presented an invited talk on the topic ‘Large-area Gold Nanomembrane by Template Transfer with a Soluble Polymer’.

Philipp presented a poster on the nanoparticle comparison project, Daniel  presented a poster titled “Reversible Ion Sensing With a Flip of a Switch”, while Ivan gave an oral talk on “Photoacoustic nanoantennae for intravascular imaging.”

Sabrina’s poster presentation was titled, “Microstructured Optical Fibers and Photoswitches: Light-Driven Sensors for Metal Ions.”

The event covered the areas of nanostructure growth, synthesis, fabrication, characterization, device design, theory, modeling, testing, applications, commercialisation, and health and safety aspects of nanotechnology.

Further information on the conference is available online.

CNBP researchers at National Proteomics Conference

Nicki Packer Low Res Edit 01257 February 2016:

The 21st Annual Lorne Proteomics Symposium, organized by the Australasian Proteomics Society, was held February 4th – 7th 2016 in Lorne, Victoria and was attended by CNBP members of the Macquarie Node, Nicolle Packer, Christopher Ashwood and Abdulrahman Shathili.

The symposium featured the latest developments in proteomics technologies and tools for the interpretation of proteomics outputs, and their application toward answering fundamental questions in biology. Invited speakers included the most cited person in the field of proteomics, Matthias Mann, as well as internationally renowned glycomics expert, Anne Dell. CNBP Chief Investigator Nicolle Packer was also an invited speaker at the event and presented a talk titled “Alterations in Glycosylation in Ovarian Cancer.”

Students Christopher Ashwood and Shathili Abdulrahman both presented posters describing results from the past year, with Christopher Ashwood being awarded a poster prize for his research on characterisation of novel protein-glycosylation using rarely used analytical techniques in the field of glycomics.

Symposium information can be found online.
