A TECHNIQUE TO ESTIMATE EMOTIONAL VALENCE AND AROUSAL BY ANALYZING IMAGES OF HUMAN FACES
In recent years, countless computer scientists worldwide have been developing deep neural network-based models that can predict people’s emotions based on their facial expressions. Most of the models developed so far, however, merely detect primary emotional states such as anger, happiness and sadness, rather than more subtle aspects of human emotion.
HIGH-SPEED 3-D MEMORY WITH FERROELECTRIC NAND FLASH MEMORY
Ferroelectric memory is a well-researched topic in the past decade due to its capacity for higher speed, lower power consumption and longer endurance, compared to conventional flash memory. The performance of ferroelectric memory can be compromised substantially due to the formation of unwanted interfacial layers during the development of ferroelectric memory-based on perovskite oxides-on-silicon. In a new report, Min-Kyu Kim, and a team of scientists in materials science and engineering at the Pohang University of Science and Technology in Korea, demonstrated a unique strategy by applying hafnia-based ferroelectrics and oxide semiconductors for three-dimensional (3-D) integration. The strategy achieved memory performance beyond the conventional flash memory and exceeded those achieved by perovskite ferroelectric memories. The team then simulated the devices to confirm the ability to realize ultra-high-density 3-D memory integration.

AIR PURIFIERS MAY DO MORE HARM THAN GOOD IN CONFINED SPACES WITH AIRBORNE VIRUSES
The positions of air inlets and outlets in confined spaces, such as elevators, greatly affect airborne virus transmission. In Physics of Fluids, researchers from University of Nicosia in Cyprus show while air purifiers would be expected to help, they may actually increase the spread.
TO FIND THE RIGHT NETWORK MODEL, COMPARE ALL POSSIBLE HISTORIES
Two family members test positive for COVID-19—how do we know who infected whom? In a perfect world, network science could provide a probable answer to such questions. It could also tell archeologists how a shard of Greek pottery came to be found in Egypt, or help evolutionary biologists understand how a long-extinct ancestor metabolized proteins.
DISCOVERY MAKES THE INVISIBLE VISIBLE
Australian scientists have discovered a new way to analyze microscopic cells, tissues and other transparent specimens, through the improvement of an almost 100-year-old imaging technique
? EARTH NEWS?:
SCIENTISTS IDENTIFY FLANK INSTABILITY AT A VOLCANO WITH HISTORY OF COLLAPSE
Landslides caused by the collapse of unstable volcanoes are one of the major dangers of volcanic eruptions. A method to detect long-term movements of these mountains using satellite images could help identify previously overlooked instability at some volcanoes, according to Penn State scientists.
SATELLITE DATA REVEALS BONDS BETWEEN EMISSIONS, POLLUTION AND ECONOMY
Burning fossil fuels has long powered world economies while contributing to air pollution and the buildup of greenhouse gases. A new analysis of nearly two decades of satellite data shows that economic development, fossil-fuel combustion and air quality are closely linked on the continental and national scales, but can be decoupled at the national level, according to Penn State scientists.
HOW TO SET AMBITIOUS GOALS FOR SUSTAINABLE AGRICULTURE
Food production in the Netherlands is an economic success but has led to many environmental issues, including nitrogen pollution. Recently, the policy to allow economic growth while reducing nitrogen losses was disapproved by the highest court in the Netherlands, casting the country into a nitrogen crisis. In a new article in the sustainability science journal One Earth, Jan Willem Erisman proposes more integrated policies for global future sustainable food production.

FIVE WAYS ARTIFICIAL INTELLIGENCE CAN HELP SPACE EXPLORATION
Artificial intelligence has been making waves in recent years, enabling us to solve problems faster than traditional computing could ever allow. Recently, for example, Google’s artificial intelligence subsidiary DeepMind developed AlphaFold2, a program which solved the protein-folding problem. This is a problem which has had baffled scientists for 50 years.
BARBS FLY OVER SATELLITE PROJECTS FROM MUSK, BEZOS
A spat erupted Tuesday between Jeff Bezos and Elon Musk as the tech titans’ space firms exchanged barbs over their rival satellite internet projects being evaluated by regulators.
? NANOTECHNOLOGY NEWS⛄☃:
RESEARCHERS CONSTRUCT MOLECULAR NANOFIBERS THAT ARE STRONGER THAN STEEL
Self-assembly is ubiquitous in the natural world, serving as a route to form organized structures in every living organism. This phenomenon can be seen, for instance, when two strands of DNA—without any external prodding or guidance—join to form a double helix, or when large numbers of molecules combine to create membranes or other vital cellular structures. Everything goes to its rightful place without an unseen builder having to put all the pieces together, one at a time.
RESEARCHERS USE NANOMATERIALS TO MAKE 2-D DIAMOND CLUSTERS AT ROOM TEMPERATURE
Atomically thin, 2-D hexagonal boron nitride (h-BN) is a promising material whose protean ability to undergo phase transformations to strong, super lightweight, chemically stable, oxidation-resistant films makes them ideal for protective coatings, nanotechnology thermal applications, deep-UV light emitters, and much more.
