RESEARCHERS EXAMINE HOW MULTILINGUAL BERT MODELS ENCODE GRAMMATICAL FEATURES
Over the past few decades, researchers have developed deep neural network-based models that can complete a broad range of tasks. Some of these techniques are specifically designed to process and generate coherent texts in multiple languages, translate texts, answer questions about a text and create summaries of news articles or other online content.
ATTACHABLE SKIN MONITORS THAT WICK THE SWEAT AWAY
A new preparation technique fabricates thin, silicone-based patches that rapidly wick water away from the skin. The technique could reduce the redness and itching caused by wearable biosensors that trap sweat beneath them. The technique was developed by bioengineer and professor Young-Ho Cho and his colleagues at KAIST and reported in the journal Scientific Reports last month.
RESEARCHERS DEVELOP SPEEDIER NETWORK ANALYSIS FOR A RANGE OF COMPUTER HARDWARE
Graphs—data structures that show the relationship among objects—are highly versatile. It’s easy to imagine a graph depicting a social media network’s web of connections. But graphs are also used in programs as diverse as content recommendation (what to watch next on Netflix?) and navigation (what’s the quickest route to the beach?). As Ajay Brahmakshatriya summarizes, “Graphs are basically everywhere.”

NEW ‘METALENS’ SHIFTS FOCUS WITHOUT TILTING OR MOVING
Polished glass has been at the center of imaging systems for centuries. Their precise curvature enables lenses to focus light and produce sharp images, whether the object in view is a single cell, the page of a book, or a far-off galaxy.
LACK OF SYMMETRY IN QUBITS CAN’T FIX ERRORS IN QUANTUM COMPUTING, MIGHT EXPLAIN MATTER/ANTIMATTER
A team of quantum theorists seeking to cure a basic problem with quantum annealing computers—they have to run at a relatively slow pace to operate properly—found something intriguing instead. While probing how quantum annealers perform when operated faster than desired, the team unexpectedly discovered a new effect that may account for the imbalanced distribution of matter and antimatter in the universe and a novel approach to separating isotopes.
OPTICAL FREQUENCY COMBS WITH A NEW DIMENSION
Periodic pulses of light forming a comb in the frequency domain are widely used for sensing and ranging. The key to the miniaturization of this technology toward chip-integrated solutions is the generation of dissipative solitons in ring-shaped microresonators. Dissipative solitons are stable pulses circulating around the circumference of a nonlinear resonator.
? EARTH NEWS?:
THERE IS NO ONE-SIZE-FITS-ALL ROAD TO SUSTAINABILITY ON “PATCHWORK EARTH”
In a world as diverse as our own, the journey towards a sustainable future will look different depending on where in the world we live, according to a recent paper published in One Earth and led by McGill University, with researchers from the Stockholm Resilience Centre.
THE MELTING OF LARGE ICEBERGS IS A KEY STAGE IN THE EVOLUTION OF ICE AGES
Antarctic iceberg melt could hold the key to the activation of a series of mechanisms that cause the Earth to suffer prolonged periods of global cooling, according to Francisco J. Jiménez-Espejo, a researcher at the Andalusian Earth Sciences Institute (CSIC-UGR), whose discoveries were recently published in Nature.
EFFECTS OF PAST ICE AGES MORE WIDESPREAD THAN PREVIOUSLY THOUGHT
Cold temperatures, prevalent during glacial periods, had a significant impact on past and modern unglaciated landscapes across much of North America, according to a recent study by University of Arkansas geologist Jill A. Marshall.
? ASTRONOMY & SPACE NEWS??:
GHOST PARTICLE FROM SHREDDED STAR REVEALS COSMIC PARTICLE ACCELERATOR
Tracing back a ghostly particle to a shredded star, scientists have uncovered a gigantic cosmic particle accelerator. The subatomic particle, called a neutrino, was hurled towards Earth after the doomed star came too close to the supermassive black hole at the center of its home galaxy and was ripped apart by the black hole’s colossal gravity. It is the first particle that can be traced back to such a ‘tidal disruption event’ (TDE) and provides evidence that these little understood cosmic catastrophes can be powerful natural particle accelerators, as the team led by DESY scientist Robert Stein reports in the journal Nature Astronomy. The observations also demonstrate the power of exploring the cosmos via a combination of different ‘messengers’ such as photons (the particles of light) and neutrinos, also known as multi-messenger astronomy.
BINARY STARS ARE ALL AROUND US, NEW MAP OF SOLAR NEIGHBORHOOD SHOWS
The latest star data from the Gaia space observatory has for the first time allowed astronomers to generate a massive 3-D atlas of widely separated binary stars within about 3,000 light years of Earth—1.3 million of them.
? NANOTECHNOLOGY NEWS⛄☃:
GRAPHENE OXIDE MEMBRANES COULD REDUCE PAPER INDUSTRY ENERGY COSTS
The U.S. pulp and paper industry uses large quantities of water to produce cellulose pulp from trees. The water leaving the pulping process contains a number of organic byproducts and inorganic chemicals. To reuse the water and the chemicals, paper mills rely on steam-fed evaporators that boil up the water and separate it from the chemicals.
