Could your lab have the next antibiotic?
Could your newly synthesised molecule kill a superbug? Matt Cooper can tell you.
His team is offering a free screening service for the world’s chemists to test their compounds against antibiotic-resistant bacteria, helping them to potentially find a new antibiotic that will fight the rise of these ‘superbugs’.
“We’re helping the community unlock the hidden value of these chemicals,” says Matt, whose team is from the Community for Open Antimicrobial Drug Discovery (CO-ADD), a not-for-profit, global initiative of The University of Queensland’s Institute for Molecular Bioscience. The screening began in February 2015, and Matt has already received thousands of samples from locations including India, Singapore, New Zealand, France, Israel, UK and the USA.
Insulin in a plant seed
An edible plant seed could deliver your insulin or cancer drugs if David Craik’s research progresses as hoped. His team’s work at The University of Queensland’s Institute for Molecular Bioscience centres on cyclotides, which are a family of exceptionally stable circular proteins that occur naturally in many plants, such as violets and petunia.
Inspired by the stability and diversity of natural cyclotides, David’s team has developed a way to join the two ends of a linear protein, allowing them to create ‘designer’ cyclotides that can be incorporated into crop plants, turning them into production factories for therapeutic drugs and insecticides.
An auto-correct system in plants could fix human gene faults
An auto-correct system for genetic errors in plants is helping plant breeders grow robust hybrid crops more efficiently. It also offers new tools for modifying human and animal proteins without modifying their genomes.

Better tasting bread for China
Murdoch University researchers have discovered how to produce better tasting and higher quality bread using new genome data for wheat grown in Australia.
How flies can help us predict the future
Dr Vanessa Kellermann, evolutionary biologist, Monash University, Melbourne
Vanessa Kellermann is working with native fruit fly species from Tasmania to tropical Queensland to find out. She has already demonstrated that tropical flies are more vulnerable to change in the long term. They don’t have the genetic capacity to evolve quickly. Now, with her L’Oréal For Women in Science Fellowship, she will explore how flexible they are in the short term—how individual insects can respond to change during their lifetimes.
“No one sets out to study flies,” she says. But they are perfect for asking basic questions that will allow us to create models of evolution and help people—from farmers to health professionals—plan for change.
When Dr Vanessa Kellermann tells people she studies flies, there’s an almost automatic assumption that she’s working to get rid of them. In fact, it’s quite the reverse. Vanessa would consider her research a success if her flies hung around for many more millions of years, along with most of the other plants and animals on Earth.

How bugs stick to our stomachs
James Whisstock and his Monash University colleagues have uncovered how the bacterium Helicobacter pylori sticks to the stomach lining, where it can cause ulcers and sometimes cancer.
The role of Helicobacter in causing gastric ulcers was originally discovered by Australian Nobel Laureates Barry Marshall and Robin Warren.
The recent work by James and his team was performed using the Australian Synchrotron and showed how the Helicobacter pylori protein SabA interacts with sugars present on the cells that line the stomach.

Infrared gets under dragon skin
Bearded dragons are revealing some of the secrets behind their colour-changing ways, thanks to the work of a Melbourne evolutionary scientist.
Devi Stuart-Fox has discovered that bearded dragons change colour in response to heat, allowing them to regulate their body temperature.
Her research opens the way for scientists to imitate lizards and develop materials that respond to light and temperature for solar energy, sensor and biomedical applications.
