DEEP LEARNING-BASED ASSESSMENT OF STUDENT
engagement could aid classroom research
Past research has identified student engagement, or the extent to which students participate and are involved in classroom activities, as a crucial factor determining both the quality of education programs and the academic performance of individual students. As a result, many educators worldwide are actively trying to devise courses that maximize student engagement.
‘LIQUID’ MACHINE-LEARNING SYSTEM ADAPTS TO CHANGING CONDITIONS
MIT researchers have developed a type of neural network that learns on the job, not just during its training phase. These flexible algorithms, dubbed “liquid” networks, change their underlying equations to continuously adapt to new data inputs. The advance could aid decision making based on data streams that change over time, including those involved in medical diagnosis and autonomous driving.
SAMSUNG ELECTRONICS PROFIT SPIKES ON PANDEMIC-DRIVEN DEMAND
Samsung Electronics, the world’s biggest smartphone and memory chip maker reported fourth-quarter net profits up by more than a quarter year-on-year Thursday, with coronavirus-driven working from home boosting demand for devices powered by its chips.

IMPROVEMENTS TO HOLOGRAPHIC DISPLAYS POISED TO ENHANCE VIRTUAL AND AUGMENTED REALITY
Researchers have developed a new approach that improves the image quality and contrast for holographic displays. The new technology could help improve near-eye displays used for virtual and augmented reality applications.
CARBON AT PRESSURES 5 TIMES THAT OF THE EARTH’S CORE BREAKS CRYSTAL FORMATION RECORD
Carbon, the fourth most abundant element in the universe, is a building block for all known life and a material that sits in the interior of carbon-rich exoplanets.
ZAPPING QUANTUM MATERIALS WITH LASERS TELLS US HOW ATOMS RELATE
Phase transitions are a fundamental piece of physics and chemistry. We’re all familiar with different phases of water, for example, but this idea of a system of particles changing what it looks like and how it behaves is really ubiquitous in science. And while we know the outcome of water changing into ice, the precise process leads to many different kinds of ice: sometimes ice is transparent and other times not, and the difference has to do with how you freeze it. Thus, studying how a phase transition happens tells us a lot about fundamental physics, and about the resulting phases on both sides.

TURNING FOOD WASTE BACK INTO FOOD
There’s a better end for used food than taking up space in landfills and contributing to global warming.
AEROSOL PARTICLES COOL THE CLIMATE LESS THAN WE THOUGHT
The impact of atmospheric aerosols on clouds and climate may be different than previously thought. That is the conclusion of cloud researcher Franziska Glassmeier from TU Delft. The results of her study will be published in Science on Friday, January 29th.
USING SCIENCE TO EXPLORE A 60-YEAR-OLD RUSSIAN MYSTERY, THE DYATLOV PASS INCIDENT
Researchers from EPFL and ETH Zurich have conducted an original scientific study that puts forth a plausible explanation for the mysterious 1959 death of nine hikers in the Ural Mountains in the former Soviet Union. The tragic Dyatlov Pass Incident, as it came to be called, has spawned a number of theories, from murderous Yeti to secret military experiment
🗞 ASTRONOMY & SPACE NEWS🌪🎇:
FIRST EVIDENCE THAT WATER CAN BE CREATED ON THE LUNAR SURFACE BY EARTH’S MAGNETOSPHERE
Before the Apollo era, the moon was thought to be dry as a desert due to the extreme temperatures and harshness of the space environment. Many studies have since discovered lunar water: ice in shadowed polar craters, water bound in volcanic rocks, and unexpected rusty iron deposits in the lunar soil. Despite these findings, there is still no true confirmation of the extent or origin of lunar surface water.
SEXTUPLY-ECLIPSING SEXTUPLE STAR SYSTEM UNCOVERED IN TESS DATA WITH AN ASSIST FROM AI
An international team of researchers led by Brian P. Powell at NASA’s Goddard Space Flight Center and Veselin P. Kostov at the SETI Institute has identified a unique system consisting of six stars. The three binary stars form a gravitationally-bound system and each pair is producing eclipses. The star system, known as TYC 7037-89-1, was uncovered in data from the Transiting Exoplanet Survey Satellite (TESS) data with a neural network designed to detect eclipsing binary stars. This newly discovered complex star system is located in the Eridanus constellation, ~1,900 light-years away from Earth.
NASA’S PERSEVERANCE ROVER 22 DAYS FROM MARS LANDING
Seven minutes of harrowing descent to the Red Planet is in the not-so-distant future for the agency’s Mars 2020 mission.
🗞 NANOTECHNOLOGY NEWS⛄☃:
RESEARCHERS CREATE POWERFUL UNIPOLAR CARBON NANOTUBE MUSCLES
For more than 15 years, researchers at The University of Texas at Dallas and their collaborators in the U.S., Australia, South Korea and China have fabricated artificial muscles by twisting and coiling carbon nanotube or polymer yarns. When thermally powered, these muscles actuate by contracting their length when heated and returning to their initial length when cooled. Such thermally driven artificial muscles, however, have limitations.
PHYSICISTS DEVELOP RECORD-BREAKING SOURCE FOR SINGLE PHOTONS
Researchers at the University of Basel and Ruhr University Bochum have developed a source of single photons that can produce billions of these quantum particles per second. With its record-breaking efficiency, the photon source represents a new and powerful building-block for quantum technologies.
RESEARCHERS USED ULTRABRIGHT X-RAYS TO IDENTIFY LITHIUM HYDRIDE AND A NEW FORM OF LITHIUM FLUORIDE
A team of researchers led by chemists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has identified new details of the reaction mechanism that takes place in batteries with lithium metal anodes. The findings, published today in Nature Nanotechnology, are a major step towards developing smaller, lighter, and less expensive batteries for electric vehicles.
