MICROSOFT’S VIVA REIMAGINES INTRANET IN POST-COVID WORLD
The promise of slowing numbers of COVID-19 cases and the development of vaccines are offering hope that workers exiled at home can get back to work again. While no one expects a rapid return to the workplace, one thing seems clear: How we work has likely changed forever.
PUSHED TO THE LIMIT: A CMOS-BASED TRANSCEIVER FOR BEYOND 5G APPLICATIONS AT 300 GHZ
Scientists at Tokyo Institute of Technology (Tokyo Tech) and NTT Corporation (NTT) have developed a novel CMOS-based transceiver for wireless communications at the 300 GHz band, enabling future beyond-5G applications. Their design addresses the challenges of operating CMOS technology at its practical limit and represents the first wideband CMOS phased-array system to operate at such elevated frequencies.
SILICON ANODE STRUCTURE GENERATES NEW POTENTIAL FOR LITHIUM-ION BATTERIES
New research conducted by the Okinawa Institute of Science and Technology Graduate University (OIST) has identified a specific building block that improves the anode in lithium-ion batteries. The unique properties of the structure, which was built using nanoparticle technology, are revealed and explained today in Communications Materials.

NEW FIBER OPTIC TEMPERATURE SENSING APPROACH TO KEEP FUSION POWER PLANTS RUNNING
The pursuit of fusion as a safe, carbon-free, always-on energy source has intensified in recent years, with a number of organizations pursuing aggressive timelines for technology demonstrations and power plant designs. New-generation superconducting magnets are a critical enabler for many of these programs, which creates growing need for sensors, controls, and other infrastructure that will allow the magnets to operate reliably in the harsh conditions of a commercial fusion power plant.
BREAKTHROUGH IN QUANTUM PHOTONICS PROMISES A NEW ERA IN OPTICAL CIRCUITS
The modern world is powered by electrical circuitry on a “chip”—the semiconductor chip underpinning computers, cell phones, the internet, and other applications. In the year 2025, humans are expected to be creating 175 zettabytes (175 trillion gigabytes) of new data. How can we ensure the security of sensitive data at such a high volume? And how can we address grand-challenge-like problems, from privacy and security to climate change, leveraging this data, especially given the limited capability of current computers?
BIMERONIUM: A NEW MEMBER OF THE TOPOLOGICAL SPIN TEXTURES FAMILY
Topological spin textures in magnetic systems are intriguing objects that exhibit exotic physics and have potential applications in information storage and processing. The most fundamental and exemplary topological spin texture is called the skyrmion, which is a nanoscale circular domain wall carrying a nonzero integer topological charge. The skyrmion texture in magnetic materials was theoretically predicted in the late 1980s, and it was experimentally observed in chiral magnets a decade ago. Since the first observation of magnetic skyrmions, the skyrmion community has focused on a series of topological spin textures evolved from the skyrmion, such as the skyrmionium and bimeron.

NASA SATELLITES HELP QUANTIFY FOREST IMPACTS ON THE GLOBAL CARBON BUDGET
Scientists have created a new method for measuring carbon fluctuations in forests; it is expected to improve the accuracy of global carbon estimates.
FINGERPRINT FOR THE FORMATION OF NITROUS OXIDE EMISSIONS
Scientists led by Eliza Harris and Michael Bahn from the Institute of Ecology at the University of Innsbruck have succeeded in studying emissions of the greenhouse gas N2O under the influence of environmental impacts in an unprecedented level of detail. The study, which has now been published in Science Advances, is thus also a starting point for the creation of models that could predict future trends in the greenhouse gas emission dynamics of ecosystems under global climate change.
RESEARCHERS STUDY BLACK CARBON AEROSOL IN URBAN BEIJING
Black carbon (BC) is the product of incomplete combustion of fossil fuels, biofuel and biomass. By strongly absorbing solar radiation, BC can heat the atmosphere, affect its stability, and further deteriorate air quality.
? ASTRONOMY & SPACE NEWS??:
STUDENT ASTRONOMER FINDS MISSING GALACTIC MATTER
Astronomers have for the first time used distant galaxies as ‘scintillating pins’ to locate and identify a piece of the Milky Way’s missing matter.
A WARP IN THE MILKY WAY LINKED TO GALACTIC COLLISION
When most of us picture the shape of the Milky Way, the galaxy that contains our own sun and hundreds of billions of other stars, we think of a central mass surrounded by a flat disc of stars that spiral around it. However, astronomers know that rather than being symmetrical, the disc structure is warped, more like the brim of a fedora, and that the warped edges are constantly moving around the outer rim of the galaxy.
SPIRou CARRIES OUT FIRST EVER MEASUREMENT OF A VERY YOUNG EXOPLANET’S DENSITY
A research team led by scientists from IRAP (CNRS/CNES/Université Toulouse III—Paul Sabatier) and IPAG (CNRS/UGA) has for the first time measured the internal density of a very young exoplanet orbiting a newly formed, extremely active star. Despite the ‘noise’ generated by the star’s activity, they successfully achieved this using the Canada-France-Hawaii Telescope (CFHT)’s planet hunting instrument SPIRou. The findings are published in MNRAS on 2 February 2021.

RESEARCHERS ENGINEER A TINY ANTIBODY CAPABLE OF NEUTRALIZING THE CORONAVIRUS
At 2 a.m. one night last April, Michael Schoof triple-checked the numbers on his screen, took a deep breath, and fired off an email he’d been waiting all day to send.
A MAGNETIC TWIST TO GRAPHENE
Electrons in materials have a property known as ‘spin,” which is responsible for a variety of properties, the most well-known of which is magnetism. Permanent magnets, like the ones used for refrigerator doors, have all the spins in their electrons aligned in the same direction. Scientists refer to this behavior as ferromagnetism, and the research field of trying to manipulate spin as spintronics.
SCIENTISTS REVEAL SYNERGISTIC EFFECTS IN DUAL SINGLE-ATOM CATALYST
Single-atom catalysts (SACs) are applied in heterogeneous catalysis. Instead of one type of single atom, dual single-atom catalysts (DSACs) deliver superior catalytic performance than SACs due to cooperation between the dual metal-atoms.
