Research raises concerns over long-term use of chromium diet pills

The synchrotron’s high energy x-ray beam.

Concerns have been raised over the long-term use of nutritional supplements containing chromium, after an Australian research team found the supplement is partially converted into a carcinogenic form when it enters cells.

The team, led by Professor Peter Lay from the University of Sydney’s School of Chemistry and Dr Lindsay Wu, now with UNSW’s School of Medical Sciences, travelled near to Chicago to Argonne National Laboratory to perform the experiments in collaboration with colleagues at Argonne’s, the Advanced Photon Source, a US Department of Energy Office of Science User Facility that generates ultra-bright, high-energy x-rays.

Dr Liz New receives OLT Teaching Excellence Award

Liz New

Congratulations to Dr Elizabeth New who has been awarded an Office of Learning and Teaching (OLT) Teaching Excellence Award (Early Career). Liz leads her chemistry students through enquiry based learning, encouraging them bring their own samples to class and formulate their own research questions so they can have a real taste of how exciting it is when they are genuinely making new discoveries.

Liz has worked with great imagination and skill in developing not only new research-enriched experiments but also an approach to assessment which has ensured that students have the attributes required in research and the wider workplace.

She has received numerous award both for her research and her work in outreach. She is a 2015 NSW Tall Poppy Award winner and was recently elected to the Australian Academy of Science's Early- and Mid-Career (EMCR) Forum executive team.

Architectures of the nanoworld


In this article Dr Markus Muellner writes about nanoengineered delivery systems that exhibit great potential to improve the treatment of many diseases. Cylindrical polymer brushes hold all the necessary criteria to be ideal drug delivery vehicles and provide access to uniform nanocylinders to study shape-induced interactions with biological systems.
