A drug based on a molecule naturally present in infants – but which declines in adulthood – can halve the scarring in brains of those who have suffered stroke. And it can be delivered up to a week afterward.
“We hope our work will improve the recovery of the elderly, as well as people in rural and remote communities, who haven’t had access to speedy treatment following a stroke,” says Associate Professor James Bourne at the Australian Regenerative Medicine Institute (ARMI), and Chief Investigator of the research.
The current treatment, a drug called tPA, is limited to ischemic strokes (caused by a blood clot). Only 10 per cent of all stroke patients qualify for treatment using the clot-busting drug, which can have harmful side-effects including haemorrhages. The optimum treatment window for tPA is within three hours of the stroke, with a 35 per cent success rate.

The life and death of cells: Jerry Adams has advanced understanding of cancer development, particularly of genes activated by chromosome translocation in lymphomas. By clarifying how the Bcl-2 protein family controls the life and death of cells, he and his colleagues at the Walter and Eliza Hall Institute of Medical Research have galvanised the development of a promising new class of anti-cancer drugs. Jerry was awarded the 2014 Macfarlane Burnet Medal. Continue reading Australian Academy of Science medals→
Terry Speed doesn’t expect to see headlines reading “Statistician cures cancer” any time soon. But he knows that maths and stats can help researchers understand the underlying causes of cancer and reduce the need for surgery.
A typhoid outbreak in Kathmandu has provided new insights into bacterial epidemics and antibiotic resistance, thanks to a Melbourne scientist’s genomic research.
Kathryn Holt, of the University of Melbourne’s Bio21 Institute, used genome sequencing to discover that an epidemic of deadly typhoid bacteria in Nepal’s capital city was driven by climate, and not by the outbreak of novel genetic strains.
Her research, published in the Royal Society journal Open Biology, changes our understanding of how typhoid spreads and how we can better respond to other bacterial epidemics.
Research on the effects of the popular joint supplement glucosamine has raised fears for women’s fertility, and a knee-jerk reaction from the vitamin industry, as Adelaide scientists reveal its threat to conception.
An obese father increases the risk of his children and grandchildren becoming obese, even if they follow a healthy diet. That’s the implication of a series of mouse studies conducted at the University of Adelaide.
