JAPANESE PAIRING LOOKING INTO USING WOOD TO BUILD SATELLITES
Sumitomo Forestry has announced a joint development project with Kyoto University to test the idea of using wood as a component in satellite construction. As part of the announcement, officials with Sumitomo Forestry told reporters that work on the project will begin with experiments designed to test different types of wood in extreme environments.
NEW AI TOOL CAN PREDICT IN SECONDS WHAT A MOVIE WILL BE RATED
Movie ratings can determine a movie’s appeal to consumers and the size of its potential audience. Thus, they have an impact on a film’s bottom line. Typically, humans do the tedious task of manually rating a movie based on viewing the movie and making decisions on the presence of violence, drug abuse and sexual content.
WHAT’S THE BEST WAY TO BOOST THE ECONOMY? INVEST IN HIGH-VOLTAGE TRANSMISSION LINES
When, in the midst of the pandemic, the Economic Society of Australia invited 150 of Australia’s keenest young thinkers to come up with “brief, specific and actionable” proposals to improve the economy, amid scores of ideas about improving job matching, changing the tax system, providing non-repayable loans to businesses and accelerating telehealth, two proposals stood out.
🗞 PHYSICS NEWS⚙♨:
METASURFACE ENABLED QUANTUM EDGE DETECTION
Metasurfaces provide unique platforms to realize exotic phenomena including negative refraction, achromatic focusing, and electromagnetic cloaking due to the engineered dielectric or metallic architectures. The intersection of metasurfaces and quantum optics can lead to significant opportunities that remain to be explored. In a new report now published on Science Advances, Junxiao Zhou, Shikai Liu and a research team in quantum information, nano-optoelectronic devices and computer engineering in China and the U.S. proposed and demonstrated a polarization-entangled photon source. They used the source to switch the optical edge mode in an imaging system to ON or OFF states based on a highly dielectric metasurface. The experiment enriched the fields of quantum optics and metamaterials as a promising direction toward quantum edge detection and image processing with a remarkable signal-to-noise ratio.
ORDER AND DISORDER IN CRYSTALLINE ICE EXPLAINED
A fascinating substance with unique properties, ice has intrigued humans since time immemorial. Unlike most other materials, ice at very low temperature is not as ordered as it could be. A collaboration between the Scuola Internazionale Superiore di Studi Avanzati (SISSA), the Abdus Salam International Centre for Theoretical Physics (ICTP), the Institute of Physics Rosario (IFIR-UNR), with the support of the Istituto Officina dei Materiali of the Italian National Research Council (CNR-IOM), made new theoretical inroads on the reasons why this happens and on the way in which some of the missing order can be recovered. In that ordered state the team of scientists have described a relatively obscure and yet fundamental property of very low temperature ice: ferroelectricity. The results, published in PNAS, are likely to extend to ice surfaces, a possibility that could be relevant to the agglomeration of ice particles in interstellar space.
🗞 EARTH NEWS🌏:
CROPS GROWN IN BANGALORE HIGH ON TOXIC HEAVY METALS
Scientists in Bangalore, India have found toxic levels of four heavy metals, chromium, nickel, cadmium and lead, in crops and vegetables grown on soil irrigated with water from six lakes in the city, reports a study published December in Current Science.
TRACTORS CAN CHANGE FARMING IN GOOD WAYS AND BAD: LESSONS FROM FOUR AFRICAN COUNTRIES
Agricultural mechanisation is on the rise in Africa, replacing hand hoes and animal traction across the continent. While around 80-90% of all farmers still rely on manual labour or draught animals, this is changing, driven by falling machinery prices and rising rural wages. During the last couple of years, tractor sales grew by around 10% annually.
SAVING THE WORLD WITH CHRISTMAS COOKIES?
Despite all warnings, people continue to ruthlessly exploit land resources around the world, planting monocultures and setting up large-scale infrastructure. Social ecologist Anke Schaffartzik analyses the political and economic interests that precede these developments and their impact on society. The snapshots of global material and energy flows, but also the power gradient of which they are a symptom, reveal that thoughtful consumption in Austria alone stands little chances against oil palm plantations in Indonesia.
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
NEW SUPERCLUSTER DISCOVERED BY ASTRONOMERS
By analyzing the data from the eROSITA Final Equatorial Depth Survey (eFEDS), an international team of astronomers has detected a new supercluster. The newly found structure consists of eight galaxy clusters. The discovery is reported in a paper published December 21 on the arXiv pre-print server.
TO HELP TRUDGE THROUGH THE SNOW, THE CHANG’E-5 RECOVERY TEAM WORE POWERED EXOSKELETONS
Other worlds aren’t the only difficult terrain personnel will have to traverse in humanity’s exploration of the solar system. There are some parts of our own planet that are inhospitable and hard to travel over. Inner Mongolia, a northern province of China, would certainly classify as one of those areas, especially in winter. But that’s exactly the terrain team members from the China Aerospace Science and Technology Corporation (CASTC) had to traverse on December 16th to retrieve lunar samples from the Chang’e-5 mission. What was even more unique is that they did it with the help of exoskeletons.
🗞 NANOTECHNOLOGY NEWS⛄☃:
ELECTRONS HOP TO IT ON TWISTED MOLECULAR WIRES
Researchers at Osaka University synthesized twisted molecular wires just one molecule thick that can conduct electricity with less resistance compared with previous devices. This work may lead to carbon-based electronic devices that require fewer toxic materials or harsh processing methods.
