Frog peptides versus superbugs

Neutrons and native frogs are an unlikely but dynamic duo in the battle against antibiotic-resistant bacteria, commonly known as superbugs, recent research has shown.

The skin secretions of the Australian green-eyed and growling grass frogs contain peptides (small proteins) that help frogs fight infection. Researchers hope these peptides will offer a new line of defence against a range of human bacterial pathogens, including methicillin-resistant Staphylococcus aureus (MRSA).

Back to the future for father of biotechnology

He’s back in the lab, working to convert the rich supply of stem cells found in the nose into specialised products to repair nerve damage or replace nerve cells lost in disorders such as hearing loss, Alzheimer’s and Parkinson’s disease.

But that’s just the latest phase in the full and distinguished life of the 2010 winner of Australia’s Prime Minister’s Prize for Science, molecular biologist Prof John Shine.

In 2011, he is stepping down after more than 20 years as executive director of Sydney’s Garvan Institute of Medical Research which, under his guidance, has grown to a staff of more than 500, an annual budget of $50 million, and now boasts significant achievements in cancer, immunology, diabetes and obesity, osteoporosis and neuroscience.

Shattering the crystal lattice

Watson and Crick’s discovery of the structure of DNA is arguably the greatest of the 20th century. The significance lies in its profound influence on our understanding of the nature of life and in its striking demonstration of the power of two disciplines – physics and biology – collaborating to solve a major problem.
