Electronic metadevices break barriers to ultra-fast communications
Researchers have come up with a new approach to electronics that involves engineering metastructures at the sub-wavelength scale. It could launch the next generation of ultra-fast devices for exchanging massive amounts of data, with applications in 6G communications and beyond. Until now, the ability to make electronic devices faster has come down to a simple principle: scaling down transistors and other components.

Autonomous steering system keeps human drivers engaged
Autonomous steering system keeps human drivers engaged
Researchers from EPFL and JTEKT Corporation have developed an automated driving system based on the concept of 'collaborative steering', which aims to increase transportation safety, efficiency, and comfort by encouraging active interaction between autonomous vehicles and their human drivers. Autonomous driving technologies have already been integrated into many mass-produced vehicles, providing human drivers with steering assistance in tasks like centering a vehicle in its lane.

Why rivers matter for the global carbon cycle
Why rivers matter for the global carbon cycle
In a new journal article, EPFL professor Tom Battin reviews our current understanding of carbon fluxes in the world's river networks. He demonstrates their central role in the global carbon cycle and argues for the creation of a global River Observation System. Until recently, our understanding of the global carbon cycle was largely limited to the world's oceans and terrestrial ecosystems.
