STEM & Society: Women and Girls in Science

These five women alone demonstrate how varied a “STEM career” can be: a researcher, an engineer, a medical director, a radio science journalist, and a STEM career strategist. If we can attract more girls into STEM fields, then we will need systemic change to create an environment they would then want to stay in. Women face many and varied cultural and systemic barriers to success; there are extra hurdles faced by all.

Optimising Healthcare

Unnecessary overtreatment costs Australia $30 billion per annum. Only 60% of diagnostics and treatments are effective, while 30% is of no or little value and 10% can be harmful. So while medical care undoubtedly provides many benefits to many people, sometimes treatments can be ineffective and sometimes even downright harmful. We could save more than 8,000 kilotons of carbon emissions by scrapping low value care that does not demonstrate any benefit.

The Evolution of Life on Earth

‘Trees are the architects of the modern world,’ says Dr Ashleigh Hood. At the end of the Devonian period, forests emerged and spread, providing a great source of oxygen via photosynthesis. So while many consider the emergence of animals to be the principal driver of contemporary life, Ashleigh’s work suggests the atmospheric oxygen provided by terrestrial plants has been foundational to the emergence of Earth’s modern biosphere.

What Can Brain Cells on a Microchip Tell Us About Intelligence?

Whether “intelligence” can be created within hardware is a fascinating question, and one that remains unanswered despite significant efforts. In contrast, biological intelligence from a neural source offers a “ground truth” of opportunity. As such, the question becomes not ‘if’ general intelligence can arise from something artificial, but ‘how’.

Tackling Invasive Species

How big is the problem of invasive species? In the words of Deakin University’s Professor Euan Ritchie, ‘the short answer is: it’s massive’. Invasive genes and species are one of the biggest environmental problems facing Australia and the number one cause of native species extinctions. They also cause immense economic and cultural damage; since the 1960s, Australia has variously spent and incurred losses amounting to $390 billion due to invasive species.
