When it comes to your heartbeat, you want it the way Goldilocks does: just right. The improper beating of the heart – whether too slow or too fast or irregular – is known as arrhythmia. Biomedical engineer Professor Natalia Trayanova is revolutionising the way we track and treat our hearts with incredible new digital technologies to assist clinicians.

Change is difficult when investment and leadership in the mental healthcare system is poor. Victoria’s monetary investment is low compared with the rest of Australia, and grossly disproportionate compared with funding for physical health.

In addition to their contribution to the city’s environmental values, urban waterways also provide important social, economic, and aesthetic benefits.

Ross fears declining investment means many of the mistakes of the past, and lessons learned, have been forgotten – and are now being repeated.

Microalgae view these as valuable nutrients, effectively removing pollutants from the water.
