Internet traffic jams may become history if ESA succeeds in developing new technology to see nearby Earth-sized planets. Why? In looking for new ways to detect planets ESA is thinking that, instead of bulky mirrors and lenses in space, one can build miniaturised optical systems that fit onto a microchip. Such ‘integrated optics’ would also allow earthly computer networks to use high-speed routing of data streams as a natural spin-off.
Data moving around the Internet are like road traffic in that a car can be driven fast down a straight road but has to slow down a great deal when changing direction at a junction. The same thing happens on information highways. Beams of light carry data along fibre-optic cables at very high speeds. When the data arrive at computers, known as servers, the servers redirect them to their final destinations. Presently, you need to convert the light signals into electricity, and that slows everything down.
Electrons move at a speed of a few kilometres per second through a circuit, whereas light travels at nearly 300 000 kilometres per second. Integrated optics would leave the data as light and simply channel it through the chip, in the right direction. Scientists call this area integrated optics, referring to the integrated circuit board on which chips are mounted. Instead of miniaturised electronics, however, miniaturised optics are placed on a microchip.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
