Election Explainer: Why Are There 150 Lower House MPs And 76 Senators?

When Australians go to the polls on July 2, they will elect 150 members of the House of Representatives. But, in 1998, there were 148 lower house MPs. So why does this number fluctuate? And what are the lowest and highest possible numbers?


What's Mother's Day If You're Born In A Machine And Raised By Robots?

As far-fetched as it may seem today, there are a couple of compelling reasons why some humans may one day be born without either a mother or father as we now know them, and with no other humans around to bring them up.


Australia's First Robotic Hip Surgeon Starts Work Today

New Relaxed Drone Regulations Will Help The Industry Take Off

The Australian drone industry is set for a shake up following the announcement of a long-awaited relaxation of regulations on their operation.

Australia’s Civil Aviation Safety Authority (CASA) says the amended regulations will come into effect in late September 2016, and with them comes the introduction of new categories of what are known as remotely piloted aircraft systems (RPAS).


Hidden Stars, Baby Planets And Blow-Up Spaceships: This Week In Space

Internet of Things (IoT) devices typically incorporate sensors, switches and logging capabilities that collect and transmit data across the internet.


How We Predict When Antarctica's Melting Ice Sheets Will Flood The Seas

Antarctica is already feeling the heat of climate change, with rapid melting and retreat of glaciers over recent decades. Ice mass loss from Antarctica and Greenland contributes about 20% to the current rate of global sea level rise. This ice loss is projected to increase over the coming century.

A recent article on The Conversation raised the concept of “climate tipping points”: thresholds in the climate system that, once breached, lead to substantial and irreversible change. Such a climate tipping point may occur as a result of the increasingly rapid decline of the Antarctic ice sheets, leading to a rapid rise in sea levels. But what is this threshold? And when will we reach it?
