TEACHING AI AGENTS TO TYPE ON A BRAILLE KEYBOARD
In recent years, computer scientists have developed artificial intelligence-based techniques that can complete a wide variety of tasks. Some of these techniques are designed to artificially replicate the human senses, particularly vision, audition and touch.
APPLE PROPOSES NEW WIRELESS CHARGING ECOSYSTEM
Apple is eyeing a better way to charge your devices.
NEW MODULE FOR OPENAI GPT-3 CREATES UNIQUE IMAGES FROM TEXT
A team of researchers at OpenAI, a San Francisco artificial intelligence development company, has added a new module to its GPT-3 autoregressive language model. Called DALL·E, the module excerpts text with multiple characteristics, analyzes it and then draws a picture based on what it believes was described. On their webpage describing the new module, the team at OpenAI describe it as “a simple decoder-only transformer” and note that they plan to provide more details about its architecture and how it can be used as they learn more about it themselves.

STUDY DEMONSTRATES THE QUENCHING OF AN ANTIFERROMAGNET INTO HIGH RESISTIVITY STATES
Antiferromagnetism is a type of magnetism in which parallel but opposing spins occur spontaneously within a material. Antiferromagnets, materials that exhibit antiferromagnetism, have advantageous characteristics that make them particularly promising for fabricating spintronic devices.
A BIT TOO MUCH: REDUCING THE BIT WIDTH OF ISING MODELS FOR QUANTUM ANNEALING
Given a list of cities and the distances between each pair of cities, how do you determine the shortest route that visits each city exactly once and returns to the starting location? This famous problem is called the ‘traveling salesman problem’ and is an example of a combinatorial optimization problem. Solving these problems using conventional computers can be very time-consuming, and special devices called ‘quantum annealers’ have been created for this purpose.
THE WORLD’S FIRST INTEGRATED QUANTUM COMMUNICATION NETWORK
Chinese scientists have established the world’s first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve quantum key distribution over a total distance of 4,600 kilometers for users across the country. The team, led by Jianwei Pan, Yuao Chen, Chengzhi Peng from the University of Science and Technology of China in Hefei, reported in Nature their latest advances towards the global, practical application of such a network for future communications.

Will global warming bring a change in the winds? Dust from the deep sea provides a clue
The westerlies—or westerly winds—play an important role in weather and climate both locally and on a global scale, by influencing precipitation patterns, impacting ocean circulation and steering tropical cyclones. So, finding a way to assess how they will change as the climate warms is crucial.
ICE ARCHES HOLDING ARCTIC’S ‘LAST ICE AREA’ IN PLACE ARE AT RISK, RESEARCHER SAYS
Snugged up against the upper edges of the Canadian Arctic Archipelago and Greenland lies the oldest and thickest sea ice in the world, covering hundreds of thousands of square kilometers of ocean. Arctic sea ice grows and shrinks with the seasons, but this ice has so far lasted even through the warmest summers on record.
isISRAEL CAN EXPECT A MAJOR EARTHQUAKE OF 6.5 ON THE RICHTER SCALE IN THE COMING YEARS
A first-of-its-kind study conducted under the bed of the Dead Sea reveals that a devastating earthquake measuring 6.5 on the Richter scale is expected to hit the region in the coming years. The study showed that an earthquake of this magnitude occurs in the land of Israel on an average cycle of between 130 and 150 years, but there have been cases in history where the lull between one earthquake and another was only a few decades long

Supergiant eclipsing binary IGR J18027–2016 investigated in detail
Using data from ESA’s XMM-Newton and NASA’s Swift spacecraft, astronomers have conducted a detailed temporal and spectral study of an eclipsing supergiant X-ray binary known as IGR J18027–2016. Results of this research provide important insights into the properties of this system.
STUDY OF NEBULA IRAS 00500+6713 SUGGESTS ITS CENTRAL STAR IS UNLIKE ANY SEEN BEFORE
A team of researchers from Potsdam University and Kazan Federal University has found evidence of a previously unknown kind of star in nebula IRAS 00500+6713. In their paper published in the journal Astronomy & Astrophysics, the group describes their study of the nebula and its central star and what they believe it represents

RESEARCHERS FABRICATE ARRAYS OF ATOMICALLY SMOOTH IRON-COATED SILICON PYRAMIDS WITH UNUSUAL MAGNETIC PROPERTIES
Ultra-small integrated circuits have revolutionized mobile phones, home appliances, cars, and other everyday technologies. To further miniaturize electronics and enable advanced functions, circuits must be reliably fabricated in three dimensions. Achieving ultrafine 3-D shape control by etching into silicon is difficult, because even atomic-scale damage reduces device performance. Researchers at Nara Institute of Science and Technology (NAIST) have published a new study in Crystal Growth and Design in which they etched silicon to adopt the shape of atomically smooth pyramids. Coating these silicon pyramids with a thin layer of iron imparted magnetic properties that until now were only theoretical.
S Ceramicsing Li, an assistant professor in mechanical engineering at Virginia Tech, has found insights into building stronger and tougher ceramics by studying the shells of bivalve mollusksa.
