Pushing the bounds of vision could reveal hidden worlds

Nature is complex – often too complex for humans to see. But squint-controlled glasses that let people see 3-D thermal images and a camera that can capture the inner workings of high-speed chemical reactions are helping ...

Bird immune systems reveal harshness of city life

They may peck greedily at feeding tables—and have it easier than country birds do in the warmer urban winters—but city birds, it turns out, are in turmoil on the inside.

The robots being readied to enter nuclear no-go zones

Robust, intelligent robots that react to their surroundings are being developed to work in situations that are too dangerous for humans, such as cleaning up Europe's decades-old radioactive waste or helping during a nuclear ...

Age and foaming—how to predict when a volcano will erupt

The eruption of a volcano can have devastating consequences – killing people and destroying livelihoods, as well as releasing vast amounts of ash into the sky that disrupts air travel and alters the climate. Knowing what ...

Robots are being programmed to adapt in real time

A robust, adaptable robot that responds to its environment on the fly and overcomes obstacles such as a broken leg without human intervention could be used to rescue people from an earthquake zone or clean up sites that are ...

Earth's magnetic poles could start to flip. What happens then?

As Earth's magnetic shield fails, so do its satellites. First, our communications satellites in the highest orbits go down. Next, astronauts in low-Earth orbit can no longer phone home. And finally, cosmic rays start to bombard ...

Record-breaking solar cells get ready for mass production

Sandwiching an oxygen-rich layer of silicon between a solar cell and its metal contact has allowed researchers in Europe to break performance records for the efficiency with which silicon solar cells convert sunlight into ...
