TACTILE AVATAR: TACTILE SENSING SYSTEM MIMICKING HUMAN TACTILE COGNITION
Tactile avatar is an artificial tactile perception and cognition system used as a surrogate for human tactile cognition with potential to produce smooth or soft and rough tactile sensations by its user. In a new report now published on Advanced Science, researchers used a piezoelectric tactile sensor to record varying physical information including pressure, temperature, hardness, sliding velocity and surface topography. In this work, Kyungsoo Kim and a team of scientists in information and communication engineering, neurology, brain and cognitive sciences in Korea engineered artificial tactile cognition by testing the tactile feelings of human participants to a variety of materials ranging from smooth or soft to rough. To account for the response variation among humans, Kim et al. designed a deep learning structure for personalization through training based on individualized histograms of tactile cognition while recording physical tactile information. The decision error of each avatar system was less than 2% for 42 different types of materials, where tactile data could be measured with 100 trials for each material. The tactile avatar machine categorized new experiences of materials based on the knowledge of the tactile training data to show a high correlation with the specific user’s approach. The scientists intend to propose an advanced method with tactile emotional exchange capabilities for advanced digital experiences in electronic devices.
WALKING QUADRUPED IS CONTROLLED AND POWERED BY PRESSURIZED AIR
Engineers at the University of California San Diego have created a four-legged soft robot that doesn’t need any electronics to work. The robot only needs a constant source of pressurized air for all its functions, including its controls and locomotion systems.
POWER OUTAGES ACROSS THE PLAINS: 4 QUESTIONS ANSWERED ABOUT WEATHER-DRIVEN BLACKOUTS
Editor’s note: Amid record cold temperatures and skyrocketing energy demand, utilities across the central U.S. have ordered rolling blackouts to ration electricity, leaving millions of people without power. Energy expert Michael E. Webber explains why weather extremes can require such extreme steps.

Lakes underneath the Antarctic ice sheet could be more hospitable than previously thought, allowing them to host more microbial life.
ELECTRICITY SOURCE DETERMINES BENEFITS OF ELECTRIFYING CHINA’S VEHICLES
Each year an estimated 1.2 million Chinese citizens die prematurely due to poor air quality. And public health consequences are particularly dire during extreme air quality events, such as infamous “Airpocalypse” winter haze episodes.
A NEW, CLEARER INSIGHT INTO EARTH’S HIDDEN CRYSTALS
Geologists have developed a new theory about the state of Earth billions of years ago after examining the very old rocks formed in the Earth’s mantle below the continents.

‘7 MINUTES OF TERROR’: A LOOK AT THE TECHNOLOGY PERSEVERANCE WILL NEED TO SURVIVE LANDING ON MARS
This month has been a busy one for Mars exploration. Several countries sent missions to the red planet in June last year, taking advantage of a launch window. Most have now arrived after their eight-month voyage.
EVIDENCE OF PLANET NINE DIMINISHING AS RESEARCHERS FIND NO EVIDENCE OF CLUSTERING
An international team of researchers has found no evidence of trans-Neptunian object clustering as part of an effort to refute the idea of the existence of Planet Nine. The group has written a paper describing their findings and have uploaded it to the arXiv preprint server.

RESEARCHERS REPORT SWITCHING MATERIAL BETWEEN SEMICONDUCTOR AND METALLIC STATES
A group of researchers from the Fritz Haber Institute of the Max Planck Society and the Humboldt-Universität zu Berlin have found out that a semiconductor can be converted to a metal and back by light more easily and more quickly than previously thought. This discovery may increase the processing speed and simplify the design of many common technological devices.
AN mRNA VACCINE FOR CANCER IMMUNOTHERAPY
Messenger RNA (mRNA) vaccines to prevent COVID-19 have made headlines around the world recently, but scientists have also been working on mRNA vaccines to treat or prevent other diseases, including some forms of cancer. Now, researchers reporting in ACS’ Nano Letters have developed a hydrogel that, when injected into mice with melanoma, slowly released RNA nanovaccines that shrank tumors and kept them from metastasizing.
NOVEL SANDWICH TECHNOLOGY IMPROVES SENSITIVITY OF RAPID TESTS
EPFL scientists have developed a method for boosting the sensitivity of rapid-detection tests like those used for the new coronavirus. The results of their feasibility study have just been published in Nano Letters.
