A Macquarie PhD student believes he’s come up with a way to turn coffee waste into biodegradable plastic coffee cups.
He’s developed a method to turn coffee grounds into lactic acid, which can then be used to produce biodegradable plastics, and is now refining the process as he finishes his PhD. Continue reading Turning coffee waste into coffee cups
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).

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.
Sugarcane is one of nature’s most efficient natural converters of sunlight, carbon dioxide and water into fuel or biomass – and as such, it is perhaps the world’s fastest growing and largest biomass agricultural crop.
