EXPLORING THE NOTION OF SHORTCUT LEARNING IN DEEP NEURAL NETWORKS
Over the past few years, artificial intelligence (AI) tools, particularly deep neural networks, have achieved remarkable results on a number of tasks. However, recent studies have found that these computational techniques have a number of limitations. In a recent paper published in Nature Machine Intelligence, researchers at Tübingen and Toronto universities explored and discussed a problem known as ‘shortcut learning’ that appears to underpin many of the shortcomings of deep neural networks identified in recent years.
MUSK: APPLE CEO DIDN’T TAKE MEETING ABOUT BUYING TESLA
Tesla CEO Elon Musk says he once considered selling the electric car maker to Apple, but the iPhone maker’s CEO blew off the meeting.
JAPAN’S RENEWABLE ENERGY SECTOR SEEKS CARBON-NEUTRAL WINDFALL
Japan needs to boost renewable energy by reforming outdated policies on land use and the national grid if it is to meet a new goal of carbon neutrality by 2050, industry players and experts say.

EXPERIMENT TAKES ‘SNAPSHOTS’ OF LIGHT, STOPS LIGHT, USES LIGHT TO CHANGE PROPERTIES OF MATTER
Light travels at a speed of about 300,000,000 meters per second as light particles, photons, or equivalently as electromagnetic field waves. Experiments led by Hrvoje Petek, an R.K. Mellon professor in the Department of Physics and Astronomy examined ideas surrounding the origins of light, taking snapshots of light, stopping light and using it to change properties of matter.
ARE TWO PHASES OF QUARANTINE BETTER THAN ONE?
New research into this question shows that the second wave of an epidemic is very different if a population has a homogenous distribution of contacts, compared to the scenario of subpopulations with diverse number of contacts.
RESEARCHERS DEVELOP NEW WAY TO BREAK RECIPROCITY LAW
An international research team lead by Aalto University has found a new and simple route to break the reciprocity law in the electromagnetic world, by changing a material’s property periodically in time. The breakthrough could help to create efficient nonreciprocal devices, such as compact isolators and circulators, that are needed for the next generation of microwave and optical communications systems.

HIGHEST LEVELS OF MICROPLASTICS FOUND IN MOLLUSCS, NEW STUDY SAYS
Mussels, oysters and scallops have the highest levels of microplastic contamination among seafood, a new study reveals.
EVIDENCE FOR A MASSIVE PALEO-TSUNAMI AT ANCIENT TEL DOR, ISRAEL
Underwater excavation, borehole drilling, and modelling suggests a massive paleo-tsunami struck near the ancient settlement of Tel Dor between 9,910 to 9,290 years ago, according to a study published December 23, 2020 in the open-access journal PLOS ONE by Gilad Shtienberg, Richard Norris and Thomas Levy from the Scripps Center for Marine Archaeology, University of California, San Diego, U.S., and colleagues from Utah State University and the University of Haifa.
CASPIAN CRISIS: SINKING SEA LEVELS THREATEN BIODIVERSITY, ECONOMY AND REGIONAL STABILITY
Coastal nations are rightly worried about sea level rise, but in the countries around the Caspian Sea, over 100 million people are facing the opposite problem: an enormous drop in sea level. Technically, this sea is a land-locked lake, but it is the largest on the planet (371.000 km2), and quite salty. Since the ’90s, the water level has been dropping a few centimeters every year. This drop will accelerate during the upcoming decades, according to scientists from the German universities of Gießen and Bremen, together with Dutch geologist Frank Wesselingh.

BLACK HOLE X-RAY BINARY GRS 1915+105 HAS A VARIABLE MAGNETIC DISC WIND, STUDY SUGGESTS
Using NASA’s Chandra spacecraft, astronomers have performed high-resolution X-ray spectroscopic observations of a transient black hole X-ray binary known as GRS 1915+105. They report that the source exhibits a variable magnetic accretion disc wind. The study was detailed in a paper published December 16 on the arXiv pre-print repository.
IMAGE: HUBBLE SEES A ‘MOLTEN RING’
The narrow galaxy elegantly curving around its spherical companion in this image is a fantastic example of a truly strange and very rare phenomenon. This image, taken with the NASA/ESA Hubble Space Telescope, depicts GAL-CLUS-022058s, located in the southern hemisphere constellation of Fornax (the Furnace). GAL-CLUS-022058s is the largest and one of the most complete Einstein rings ever discovered in our universe. The object has been nicknamed by astronomers studying this Einstein ring as the “Molten Ring,” which alludes to its appearance and host constellation.

NANOMATERIAL THEORY DESCRIBES STRONGLY CORRELATED ELECTRONS IN QUANTUM DOTS
Osaka City University scientists have developed mathematical formulas to describe the current and fluctuations of strongly correlated electrons in quantum dots. Their theoretical predictions could soon be tested experimentally.
RESEARCHERS REALIZE HALF-METALLICITY IN A-TYPE ANTIFERROMAGNETS WITH FERROELECTRIC CONTROL
Recently, Prof. Zheng Xiaohong’s research group from the Institute of Solid State Physics (ISSP) of the Hefei Institutes of Physical Science (HFIPS), in cooperation with Prof. Stefano Sanvito from Trinity College Dublin, demonstrated a novel idea to achieve half-metallicity in A-type van der Waals (vdW) antiferromagnets via ferroelectric control.
