How shiny are near-Earth objects?

Near-Earth objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth. NEOs are consequently potential collision threats, but scientists are also interested in them because they offer ...

A new sensor for light, heat and touch

Inspired by the behaviour of natural skin, researchers at the Laboratory of Organic Electronics, Linkoping University, have developed a sensor that will be suitable for use with electronic skin. It can measure changes in ...

Bionics: Electric view in murky waters

When dealing with disasters or searching for objects, robots or drones with cameras are usually used. However, conventional cameras are of rather limited use in murky, dark water, such as in a sewage pipe or a lake that is ...

Spin lasers facilitate rapid data transfer

Engineers at Ruhr-Universität Bochum have developed a novel concept for rapid data transfer via optical fibre cables. In current systems, a laser transmits light signals through the cables and information is coded in the ...

Designing next-generation optical antennas

Antennas catch radio waves, a form of electromagnetic radiation, from the air and convert the energy into electrical signals that feed modern telecommunications. They can also convert electrical signals into radio waves. ...

SNoOPI: A flying ace for soil moisture and snow measurements

Work has begun on a new CubeSat mission that will demonstrate for the first time a new, highly promising technique for measuring soil moisture from space—data important for early flood and drought warnings as well as crop-yield ...
