One of the greatest feats of human migration in history was the colonisation of the vast Pacific Ocean by Polynesian peoples. They achieved it thanks to their sophisticated knowledge of positional astronomy and celestial navigation.

The Disney film Moana has drawn attention to these accomplishments and helped inform a new generation about the complexity of Indigenous astronomy.

Back in 2010 Sony Australia's Paul Colley forecasted that a large percentage of Australian viewers would have 3D televisions by 2014. In the same year, industry pundits such as Simon Murray predicted that sales of 3D TVs were set to increase in the years to come.

But others were heralding the death of 3D TVs and this year the remaining major manufacturers, LG and Sony, have said they will no longer produce 3D-capable televisions. So despite all the repeated push and positive predictions, what went wrong with 3D TV?

For many years, schools and universities have had to change the way they work and teach in order to fit in with technology.

Software like PowerPoint, for example, which has long been used as an education tool, wasn’t designed for education. Nonetheless, it has been a staple tool in education settings, used as a way to present information in template, bite-size formats.

For as long as humans have been interacting with new media technologies, they have also created monsters to haunt them. When photography became mainstream in the late 19th century, for example, it wasn’t long before entertainers and spiritualists were using the technology to “capture spirits” through the process of double exposure.

Similarly, the radio, the telegraph, the cinema and video have all become, at various points, “haunted” as their presence in modern life became more ubiquitous.

It is therefore unsurprising that the internet gave birth to its own boogieman: a supernatural creature called the Slenderman. The preternaturally tall and faceless man in a black suit is the subject of the HBO documentary Beware The Slenderman.

The Russian hacking of the Democratic National Committee over the past two years might seem like a very American news story, inseparable from the lead characters of Hillary Clinton and Donald Trump, and hyped as only the polarised media of that country can do it.

But when we look more deeply, we see a very threatening reality that concerns all governments, liberal democratic or authoritarian. Australia should take note.

Most modern fitness trackers are electronic devices you wear on your wrist to track steps, overall physical activity, sedentary behaviour and sleep. They typically work with a smartphone app or website that allow you to track your progress over time using graphs and figures. Advanced fitness trackers can also record heart rate and GPS related outcomes, like your route, speed and distance.
