Smart metamaterials that sense and reprogram themselves

Materials scientists aim to engineer intelligence into the fabric of materials or metamaterials for programmable functions. Engineering efforts can vary from passive to active forms to develop programmable metasurfaces using dynamic and arbitrary electromagnetic (EM) wavefields. Such metasurfaces, however, require manual control to switch between functions. In a new study now published on Light: Science & Applications, Qian Ma and an interdisciplinary research team in the State Key Laboratory, Cyberspace Science and Technology, and the Department of Electronics in China engineered a smart metasurface for self-adaptive programmability.

'Messy' production of perovskite material increases solar cell efficiency

Scientists at the University of Cambridge studying perovskite materials for next generation solar cells and flexible LEDs have discovered that they can be more efficient when their chemical compositions are less ordered, vastly simplifying production processes and lowering cost.

A distinct spin on atomic transport

One of the more unexpected things that can be done with charge-neutral atoms is using them to emulate the fundamental behavior of electrons. Over the past few years, the group of Tilman Esslinger at the Institute of Quantum Electronics in the Department of Physics of ETH Zurich has pioneered a platform in which atoms cooled to temperatures close to absolute zero are transported through one- and two-dimensional structures, driven by a potential difference. In this way, defining phenomena occuring in mesoscopic electronic systems can be studied in great detail, including quantized conductance. In a pair of papers published today in Physical Review Letters and Physical Review A, postdoc Laura Corman, former Ph.D. student Martin Lebrat and colleagues in the Esslinger group report that they have mastered in their transport experiments control over quantum spin.

New particle analysis technique paves way for better air pollution monitoring

A new technique for continuously monitoring both the size and optical properties of individual airborne particles could offer a better way to monitor air pollution. It is especially promising for analyzing fine particulate matter measuring less than 2.5 microns (PM2.5), which can reach deep into the lungs and cause health problems.

LHCf gears up to probe birth of cosmic-ray showers

Cosmic rays are particles from outer space, typically protons, travelling at almost the speed of light. When the most energetic of these particles strike the atmosphere of our planet, they interact with atomic nuclei in the atmosphere and produce cascades of secondary particles that shower down to the Earth's surface. These extensive air showers, as they are known, are similar to the cascades of particles that are created in collisions inside particle colliders such as CERN's Large Hadron Collider (LHC). In the next LHC, run starting in 2021, the smallest of the LHC experiments—the LHCf experiment—is set to probe the first interaction that triggers these cosmic showers.

Non-volatile control of magnetic anisotropy through change of electric polarization

Researchers at Kanazawa University controlled the magnetic properties of a metal layer through the electrical polarization of a neighboring metal oxide layer. Computational simulations and experimental measurements revealed that the magnetism of a cobalt-platinum alloying layer strongly depended on the polarization direction of an overlying magnesium zinc oxide layer. The concept of magnetic property control using electrical polarization shows potential to advance the development of nonvolatile magnetic memory.

Astronomy & Space news

Astronomers investigate a curious case of a supernova connected with gamma-ray burst

Using a set of space and ground-based telescopes, an international team of astronomers has conducted a detailed study of the supernova SN 2017htp associated with the gamma-ray burst GRB 171010A. Results of the study, presented in a paper published October 26 on arXiv.org, could shed more light on the nature of such phenomena.

Small satellite to study resources needed for sustained lunar presence

As we venture forward to the Moon and establish a sustained lunar presence, finding and understanding water on the lunar surface becomes increasingly important. Lunar water is largely in the form of, but not necessarily limited to, water ice. Astronauts on the Moon could use this ice for various crew needs, potentially including rocket fuel. The Lunar IceCube mission, led by Morehead State University in Morehead, Kentucky, will study water distribution and interaction on the Moon. The mission will carry a NASA instrument called Broadband InfraRed Compact High-Resolution Exploration Spectrometer (BIRCHES) to investigate the distribution of water and other organic volatiles. NASA scientists will use this data to understand where the water is on the Moon, its origins and how we can use it.

Image: Hubble touts a team of stars

Within a galaxy hosting around 300 billion stars, here the NASA/ESA Hubble Space Telescope has captured a mere handful or two—just about enough to form a single football team. These stellar "teammates" play under the banner of NGC 1333, the cloud of gas and dust that formed them and that they continue to call home.

Near-Earth asteroid pairs offer clues to composition, dynamics and environmental conditions of early solar system

Near Earth Objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth, making them potential collision threats. NEOs also offer clues to the composition, dynamics and environmental conditions of the early solar system and its evolution, and because they are relatively close to the Earth they lend themselves to astronomical measurements. Most NEOs are discovered in optical searches, but one crucial NEO parameter, its size, usually cannot be determined from optical detections alone. This is because an NEO's optical light is reflected sunlight, and an object can be bright either because it is large or because it has a high reflectivity. A CfA team has been using the IRAC infrared camera on Spitzer to measure NEO infrared emission signals which provide an independent measure of its size.

How to see stars and tackle light pollution in your own backyard

Technology news

A deep learning technique to generate real-time lip sync for live 2-D animation

Live 2-D animation is a fairly new and powerful form of communication that allows human performers to control cartoon characters in real time while interacting and improvising with other actors or members of an audience. Recent examples include Stephen Colbert interviewing cartoon guests on The Late Show, Homer answering live phone-in questions from viewers during a segment of The Simpsons, Archer talking to a live audience at ComicCon, and the stars of Disney's Star vs. The Forces of Evil and My Little Pony hosting live chat sessions with fans via YouTube or Facebook Live.

New tool highlights what generative models leave out when reconstructing a scene

Anyone who has spent time on social media has probably noticed that GANs, or generative adversarial networks, have become remarkably good at drawing faces.

Stress testing the healthcare system

Scientists at the Complexity Science Hub Vienna (CSH) have developed a stress test to determine the resilience of regional health care in real time. They used a 1:1 computer model of the Austrian primary health care system in the form of patient flows in regional physician networks as a basis. The innovative model provides concrete answers to questions: How important is a certain doctor for the functioning of primary care in my region? How many and which doctors' retirements can the system absorb? At what point can primary health care no longer be guaranteed for everyone in a region?
