Apart from the much-hyped AR/VR headset, Apple seems to be working on a new AR headset. According to sources, the Cupertino-based tech giant is eyeing 2024 to launch its first-ever AR glasses.
Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed an upcycling approach that adds value to discarded plastics for reuse in additive manufacturing, or 3D printing. The readily adoptable, scalable method introduces a closed-loop strategy that could globally reduce plastic waste and cut carbon emissions tied to plastic production.
Results published in Science Advances detail the simple process for upcycling a commodity plastic into a more robust material compatible with industry 3D-printing methods.
The team upgraded acrylonitrile butadiene styrene, or ABS, a popular thermoplastic found in everyday objects ranging from auto parts to tennis balls to LEGO blocks. ABS is a popular feedstock for fused filament fabrication, or FFF, one of the most widely used 3D-printing methods. The upcycled version boasts enhanced strength, toughness and chemical resistance, making it attractive for FFF to meet new and higher performance applications not achievable with standard ABS.
Scientists from the Institute of Industrial Science at The University of Tokyo fabricated three-dimensional vertically formed field-effect transistors to produce high-density data storage devices by ferroelectric gate insulator and atomic-layer-deposited oxide semiconductor channel. Furthermore, by using antiferroelectric instead of ferroelectric, they found that only a tiny net charge was required to erase data, which leads to more efficient write operations. This work may allow for new, even smaller and more eco-friendly data-storage memory.
While consumer flash drives already boast huge improvements in size, capacity, and affordability over previous computer media formats in terms of storing data, new machine learning and Big Data applications continue to drive demand for innovation. In addition, mobile cloud-enabled devices and future Internet of Things nodes will require memory that is energy-efficient and small in size. However, current flash memory technologies require relatively large currents to read or write data.
Now, a team of researchers at The University of Tokyo have developed a proof-of-concept 3D stacked memory cell based on ferroelectric and antiferroelectric field-effect transistors (FETs) with atomic-layer-deposited oxide semiconductor channel. These FETs can store ones and zeros in a non-volatile manner, which means they do not require power to be supplied at all times. The vertical device structure increases information density and reduces operation energy needs. Hafnium oxide and indium oxide layers were deposited in a vertical trench structure. Ferroelectric materials have electric dipoles that are most stable when aligned in the same direction. Ferroelectric Hafnium Oxide spontaneously enables the vertical alignment of the dipoles. Information is stored by the degree of polarization in the ferroelectric layer, which can be read by the system owing to changes in electrical resistance.
A detailed analysis of the composition and motion of more than 500 stars has revealed conclusive evidence of an ancient collision between Andromeda and a neighboring galaxy. The findings, which improve our understanding of the events that shape galaxy evolution, were presented by Carnegie’s Ivanna Escala Monday at the meeting of the American Astronomical Society.
Galaxies grow by accreting material from nearby objects—other galaxies and dense clumps of stars called globular clusters —often in the aftermath of a catastrophic crash. And these events leave behind relics in the form of stellar associations that astronomers call tidal features. This can include elongated streams or arcing shells moving around the surviving galaxy. Studying these phenomena can help us understand a galaxy’s history and the forces that shaped its appearance and makeup.
“The remnants of each crash can be identified by studying the movement of the stars and their chemical compositions. Together this information serves as a kind of fingerprint that identifies stars that joined a galaxy in a collision,” Escala explained.
Over the years, Masset, B.C., master carver Jaalen Edenshaw has advocated for clean energy use on the archipelago, a region that is disconnected from B.C. Hydro’s main electricity grid and mainly reliant on diesel.
Since last October, the Haida carver has been teaming up with brother Gwaai to carve a totem pole in honour of Kaay’ahl Laanas hereditary chief Watson Price (Gaahlaay) at a workshop in Masset powered by 18 solar panels that can generate as much as 40 kWh of electricity a day — enough to fully charge a small electric car.
Edenshaw, a member of the Ts’aahl Eagle Clan, is renowned for his traditional creations, including masks, canoes, and 13-metre high red cedar totem poles that are on display in galleries around the world.
Space Exploration Technologies Corp., better known as SpaceX, has pulled in another $1.7 billion in equity funding, according to a filing Monday.
Privately held SpaceX, led by Tesla Inc. TSLA,-7.10% Chief Executive Elon Musk, sold about $1.68 billion in new equity in a $1.72 billion offering, according to the Securities and Exchange Commission filing. The first sales occurred late last month, it said.
Cancer, in the simplest terms, is the transformation of normal cells into malignant ones that grow and divide uncontrollably. It, however, is not one disease but a group of more than 100 different and distinctive diseases, and leukemia, or blood cancer, is just one of them. Leukemia begins in…
Google suspended an engineer who contended that an artificial-intelligence chatbot the company developed had become sentient, telling him that he had violated the company’s confidentiality policy after it dismissed his claims.
Blake Lemoine, a software engineer at Alphabet Google, told the company he believed that its Language Model for Dialogue Applications, or LaMDA, is a person who has rights and might well have a soul. LaMDA is an internal system for building chatbots that mimic speech.
SpaceX’s Starlink satellite internet service is gearing up to activate its satellites in polar regions, which might include laser coverage.
