I work in the field of bioprinting, where the aim is to build biological tissues by printing living cells into 3D structures.

Last month I found my Facebook news feed plastered with an amazing story about “the first 3D printed heart using a patient’s own cells”. A video showed a beautiful, healthy-looking heart apparently materializing inside a vat of pinkish liquid.

Australia has changed in many ways over the past two decades. Rising house prices, country-wide improvements in education, an aging population, and a decline in religious affiliation, are just some of the ways it has changed. At the same time, political power has moved back and forth between the two major parties. How much can we attribute changes in political power to changes in who we are?

Quite a lot, as it turns out.

Finding the ‘average’ electorate

We analyzed election results from 2001 to 2016 and mapped them against data from the census to see how socio-demographic characteristics influence voting patterns, and how this has changed over time.

In the Chinese science fiction film The Wandering Earth, recently released on Netflix, humanity attempts to change the Earth’s orbit using enormous thrusters in order to escape the expanding sun – and prevent a collision with Jupiter.

The scenario may one day come true. In five billion years, the sun will run out of fuel and expand, most likely engulfing the Earth. A more immediate threat is a global warming apocalypse. Moving the Earth to a wider orbit could be a solution – and it is possible in theory.

Biogen recently announced that it was abandoning its late stage drug for Alzheimer’s, aducanumab, causing investors to lose billions of dollars.

They should not have been surprised.

Testosterone is the main sex hormone in men. It’s best known for its role in the development of male sexual characteristics and physical features, but there are also many surprising and lesser known functions of testosterone that make it an important hormone in health and disease. Identifying whether someone has too much or too little testosterone can predict future diseases and even treat them. But knowing what is high, low or normal for an individual isn’t straightforward.

These days, anybody with an internet connection can be a publisher.

That doesn’t make everybody a journalist.

This distinction has become more important than ever in light of two recent events.
