A way to laser print colors that will not fade using tiny columns

(—A team of researchers at the Technical University of Denmark has developed a way to print colors onto a surface without using ink and which will not fade. In their paper published in the open-access journal Sciences Advances, the group describes the inspiration for their approach, how it works, their results and the one thing they still need to solve before their technique can be industrialized.

First underwater carpet cloak realized with metamaterial

Researchers at the Institute of Acoustics (IOA) of the Chinese Academy of Sciences have designed and fabricated an underwater acoustic carpet cloak using transformation acoustics, a scientific first. The research was published online in Scientific Reports on April 6.

Space radiation reproduced in the lab for better, safer missions

Man-made space radiation has been produced in research led by the University of Strathclyde, which could help to make space exploration safer, more reliable and more extensive.

Quantum entanglement: Violation of Bell's inequality on frequency-bin entangled photon pairs

Making use of a specifically-developed slow light technique to reduce the velocity of light dramatically, researchers implemented a Bell Test and were able to generate frequency-bin entangled narrowband biphotons from spontaneous four-wave mixing (SFWM) in cold atoms with a double-path configuration, where the phase difference between the two spatial paths can be controlled independently and nonlocally.

Physicists demonstrate photonic hypercrystals for control of light-matter interaction

Control of light-matter interaction is central to fundamental phenomena and technologies such as photosynthesis, lasers, LEDs and solar cells. Researchers have now demonstrated a new class of artificial media called photonic hypercrystals that can control light-matter interaction in unprecedented ways.

Scientists develop device to predict clear-sky turbulence for safer air travel

Turbulence in clear skies comprises the most unpleasant kind of vortex drifts in air travel. These occur in cloudless space with perfect visibility when an airplane travels between air flows that differ in direction, speed of movement, temperature and density. This is the kind of turbulence that Aeroflot flight SU-270 from Moscow to Bangkok experienced, resulting in 27 injuries of varying severity.

NASA News Conference, Media Availability with Next Space Station Crew

NASA astronauts Joe Acaba and Mark Vande Hei and their Russian crewmate Alexander Misurkin, who are part of an upcoming International Space Station crew, will conduct a news conference and be available for media interviews Wednesday, May 10, at NASA’s Johnson Space Center in Houston.

New math techniques to improve computational efficiency in quantum chemistry

Researchers have developed new mathematical techniques to advance the study of molecules at the quantum level. Mathematical and algorithmic developments along these lines are necessary for enabling the detailed study of complex hydrocarbon molecules that are relevant in engine combustion.

With more light, chemistry speeds up

Light initiates many chemical reactions. Experiments have for the first time demonstrated that increasing the intensity of illumination some reactions can be significantly faster. Here, acceleration was achieved using pairs of ultrashort laser pulses.

NASA Awards Omnibus Multidiscipline Engineering Services Contract

NASA has awarded the Omnibus Multidiscipline Engineering Services (OMES) II contract to Science Applications International Corporation (SAIC) of McLean, Virginia, to support the Applied Engineering and Technology Directorate, located at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
