The Australian National University is turning to digital proctoring to replace the role of a walking invigilator. But who watches the proctor, what are the risks, and what data will be collected?
'Smart cities', featuring networks of automatic lights, video cameras and environmental sensors, have been hailed as an enhancement to urban life. But they are also tools of surveillance and control.
A new study lays out a road map for protecting and restoring 50% of Earth's surface, targeted to preserve biodiversity and maximize natural removal of carbon from the atmosphere.
It's cheaper to prevent biological invasions than to react after they happen. But it's hard to detect invaders while there are still just a few of them. Knowing when and where to look can help.
Drones are low cost and easy to operate. They give quality, high resolution outputs, and can be deployed fast and often.

Tracking wild animals can provide lots of valuable data. New research suggests audio recordings of wild wolves can replace the typical radio collars, which can be expensive and intrusive.
In the aftermath of fires or logging, conservation needs to focus on recovering the health of the remaining vegetation, not just the size of the forest or woodland.
