The STEM Six: the best of STEM this week (August 31 2018)

By Carl Jackson

Ever dreamt of travelling through time or having your own bionic implants? There are a couple of stories in this week’s round-up you’re going to be particularly interested in.

Here are a few of the stories from science, technology, engineering and mathematics that caught our attention over the last week.

1. Physicists say they’ve come up with a mathematical model for a viable time machine

Everyone’s fantasised about hopping in a time machine, whether to go and walk among the dinosaurs or simply stop yourself that time you waved to someone in the street before realising they weren’t who you thought they were. According to University of British Columbia’s Ben Tippett and University of Maryland’s David Tsang, travelling through time is in fact mathematically possible. Don’t get too excited though; there are a lot of practical things to work out before you start hopping through time.

2. Citizens, not technology, the key to government systems transformation

There’s a strong push to introducing greater automation and Artificial Intelligence to upgrade government department and agency systems, but this push should always be lead by the needs of citizens. The University of Melbourne’s Professor Marcello La Rosa outlines his challenge to governments — rather than requiring citizens to mold to established processes, start taking a wider view and see where they interact with services.

Would you have a small microchip inserted under your skin to make your life more convenient? Swedish biohacker Hannes Sjöblad argues that in the future this technology will replace everything from your credit card to your house key.

5. Deepfakes for dancing

Face-swapping deepfakes (where AI is used to manipulate videos by swapping one person’s face on to another’s head) have received a lot of recent attention, but now there’s a new type of deepfake — dancing deepfakes. Researchers at UC Berkley have developed a system capable of taking an individual’s movements and synthesising video of the target individual based on the stick figure movements of the source. Possibly a useful technology for certain world leaders receiving a bit of attention for their awkward dancing lately.

6. Smart membranes the key to capturing carbon
