Superconducting circuits, simplified: New circuit design could unlock the power of experimental superconducting computer chips

Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today's chips, an attractive trait given the increasing power consumption of the massive data centers that power the Internet's most popular sites.

Shown here is a square-centimeter chip containing the nTron adder, which performed the first computation using the researchers' new superconducting circuit.

Boeing Concludes Commercial Crew Space Act Agreement for CST-100/Atlas V

Boeing has successfully completed the final milestone of its Commercial Crew Integrated Capability (CCiCap) Space Act Agreement with NASA. The work and testing completed under the agreement resulted in significant maturation of Boeing’s crew transportation system, including the CST-100 spacecraft and Atlas V rocket.

Plastic nanoparticles also harm freshwater organisms

Organisms can be negatively affected by plastic nanoparticles, not just in the seas and oceans but in freshwater bodies too. These particles slow the growth of algae, cause deformities in water fleas and impede communication between small organisms and fish. These are the results of research carried out by Wageningen University and IMARES, part of Wageningen UR, published in the latest issue of Environmental Science and Technology. It is the first time that such effects of plastic on freshwater organisms have been studied.

Plastic in the oceans (plastic soup) has been thought to seriously affect aquatic life for some time, but until now little research has been carried out into the levels and effects of plastics in the freshwater environment. ‘The main sources of plastic are on land, so it is important to also look at the effects of plastic on land', says Professor Bart Koelmans, leader of the Wageningen University and IMARES research group. ‘We know that nanoplastic particles are released during processes such as the thermal cutting of plastics and 3D printing and when small plastic particles are abrasion by sand - a process that probably also takes place in nature.'

Saturn Moon May Hide a 'Fossil' Core or an Ocean

A new study focused on the interior of Saturn's icy moon Mimas suggests its cratered surface hides one of two intriguing possibilities: Either the moon's frozen core is shaped something like a football, or the satellite contains a liquid water ocean.

Magnetic mirrors enable new technologies by reflecting light in uncanny ways

This is an artist's impression of a comparison between a magnetic mirror with cube-shaped resonators (left) and a standard metallic mirror (right). The incoming and outgoing electric field of light (shown as alternating red and white bands) illustrates that the magnetic mirror retains light's original electrical signature while a standard metallic mirror reverses it upon reflection.

NASA’s Hubble Telescope Finds Potential Kuiper Belt Targets for New Horizons Pluto Mission

14-281_0_0.jpg
This is an artist’s impression of a Kuiper Belt object (KBO), located on the outer rim of our solar system at a staggering distance of 4 billion miles from the Sun. A HST survey uncovered three KBOs that are potentially reachable by NASA’s New Horizons spacecraft after it passes by Pluto in mid-2015

Construction Secrets of a Galactic Metropolis

Astronomers have used the APEX telescope to probe a huge galaxy cluster that is forming in the early Universe and revealed that much of the star formation taking place is not only hidden by dust, but also occurring in unexpected places. This is the first time that a full census of the star formation in such an object has been possible.
