Machine learning may not seem to have much connection with wildlife, but it’s starting to play a central role in bird conservation.
A cultural collaboration with deafblind people led to the development of a high-tech device to help navigate their world post-lockdown
Various innovations after the past century have improved the world for many - but there’s still much more for universities to do.
Satellite telemetry, tiny geolocation tags and passive acoustic recording are providing new insights into bird migration and vital data for conservation.
You can’t photograph the inside of a twister, but radar offers some clues.
Two new NASA missions – VERITAS and DAVINCI+ – are headed to Venus. The missions will use radar and a probe to learn about Earth’s hard-to-study and potentially prophetic neighbor.
The murky blobs visible with today’s wall-penetrating radar could soon give way to detailed images of people and things on the other side of a wall – and even measure people’s breathing and heart rate.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
Saturn’s largest moon has been fully mapped for the first time.
Citizens-watch programs designed by police to aid anti-trafficking efforts threaten the rights and safety of sex workers.
The flood zone around Townsville extends for hundreds of kilometres, making monitoring difficult even from the air. But scientists are testing a new satellite method that can peer through the clouds.
Our work with the BBC’s Animals With Cameras showed one family of meerkats had excavated a huge tangle of tunnels.
New “dual-pol” weather radars promise to spot large hailstones forming inside thunderstorms, giving people a heads-up when it’s about to hail.
It’s been five decades of microwave popcorn and piping hot leftovers in home kitchens. A serendipitous discovery helped engineers harness radar to create this now ubiquitous timesaving appliance.
Without a human operator on board, how can a drone steer clear of collisions? Technology from autonomous cars can help.
Tracking the flight of the bumblebee teaches us how they use plants – and how we can help them.
Nanophotonics deals with photons at the nanometre scale, and it’s set to transform everything from internet speeds to turning your smartphone into a portable science lab.
Modern technology is helping archaeologists to discover buried sites without risking to damage them.
The face-off between Russia and the West in Syria is giving both sides a chance to try out their new high-tech weaponry.
