An international study led by Monash University astronomers focusing on an infamous star in Orion may help to shed light on how the solar system formed.
In 1936, over the course of the year, a previously unremarkable faint star in Orion, FU Ori, became 250 times brighter.
“FU Ori has remained bright ever since,” said Elisabeth Borchert, the lead author of the study to be published in the Monthly Notices of the Royal Astronomical Society (MNRAS).
Alphabet’s AI research company DeepMind has released the next generation of its language model, and it says that it has close to the reading comprehension of a high schooler — a startling claim.
It says the language model, called Gopher, was able to significantly improve its reading comprehension by ingesting massive repositories of texts online.
DeepMind boasts that its algorithm, an “ultra-large language model,” has 280 billion parameters, which are a measure of size and complexity. That means it falls somewhere between OpenAI’s GPT-3 (175 billion parameters) and Microsoft and NVIDIA’s Megatron, which features 530 billion parameters, The Verge points out.
Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered scientists’ previous beliefs about the sound wave, opening an avenue to the development of novel applications in acoustic communications, acoustic sensing, and imaging.
The research was initiated and co-led by Dr. Wang Shubo, Assistant Professor in the Department of Physics at CityU, and conducted in collaboration with scientists from Hong Kong Baptist University (HKBU) and the Hong Kong University of Science and Technology (HKUST). It was published in Nature Communications, titled “Spin-orbit interactions of transverse sound.”
SpaceX has work to do, Tesla sells Cyberquad, Elon Musk gets a haircut.
SpaceX is granted three additional NASA missions, Tesla sells out a Cyberquad for kids, Cybertruck pending, and Elon Musk gets a heavily-memed haircut.
A new robotics startup, Petra, emerged from stealth today with funding of $33 million and a promising new technology for the mining industry.
According to Gates, tech such as VR goggles and motion-capture gloves would be needed to accurately capture a user’s body language and expressions.
The South African satellite, SumbandilaSat (Pathfinder in Venda) is reaching the end of its life and will deorbit on Friday 10 December 2021.
The satellite was launched in 2009 and took a total of 1,128 high-resolution, usable images. In addition, these imageries were applied in local research and on the Copernicus (previously GMES: Global Monitoring for Environment and Security) programme. The data also contributed towards disaster management such as flood monitoring in Namibia and fire campaigns in the Kruger National Park in South Africa. Furthermore, it also recorded timely images of the Fukushima nuclear disaster and the Tuscaloosa tornado in the USA.
In May 2005, the then DST (Department of Science and Technology) of the South African Government commissioned Stellenbosch University and SunSpace to develop the ZASat pathfinder satellite program (later renamed SumbandilaSat), a technology demonstrator in conjunction with the South African industry. Consequently, SumbandilaSat was delivered 15 months later and launched from Baikonur, Kazakhstan on September 17 2009 with monitoring and satellite support from the SANSA Space Operations facility in Hartebeesthoek.
If December 22’s launch goes as planned then the engineers behind the $10 billion James Webb Space Telescope (JWST or “Webb” for short) are in for a nervous Christmas.
Forget that it was originally conceived in the 1990s and was first expected to launch in 2007. Forget also the initial rocket launch—usually viewed as the most nerve-wracking moment. This time it’s not the European Space Agency’s Ariane 5 rocket—due to lift Webb into space from the Guiana Space Center, Kourou, French Guiana on December 18, 2021—that’s giving engineers sleepless nights. It’s the 29 days of “space origami” they’ll have to endure after the launch as Webb unfolds from its collapse state into a “giant sunflower.”
You see, the technological marvel that is Webb is fully assembled, but folded into the 5.4 meter/17.7ft. fairing of the Ariane 5 for launch—the largest rocket fairing NASA could find. When it’s in-situ a whopping million miles/1.5 million kilometers from Earth at the second Lagrange point (L2) —almost certainly too far away for astronauts to fix if the worst happens—it will resemble a huge sunflower once unfurled.
And it would create 4.7 million long-term jobs.
The United States’ energy system that’s running completely on wind, water, and solar, combined with storage, would not only avoid blackouts but also lower energy requirements and consumer costs, a Stanford University study has shown. In addition, this would create millions of jobs, improve health, and free up land for various other purposes.
This is incredibly important because, for some people, a future powered by renewable energy isn’t feasible due to concerns about blackouts driven by inconsistent electricity sources. Take, for example, the grid blackouts caused by extreme weather events in California in August 2020 and Texas in February 2021.
However, the study, which examined grid stability under various scenarios in which wind, water, and solar energy supplied 100 percent of all energy needs in the U.S., has now demonstrated that those concerns are misplaced.

The auto-retracting system can be deployed when solar energy is needed.
California-based energy firm Xponent Power developed an auto-retracting Xpanse Solar Awning that can be deployed if and when solar energy is needed, a report from New Atlas reveals.
The retractable solar panels move out to the side of the RV, creating a nice bit of shade for travelers, at the same time as providing on-demand solar energy. Depending on the model, owners will get 800, 1,000, or 1,200 watts of charging power.
The off-grid solution was designed to allow RV owners to camp away from electrical sockets for days at a time, and it can be easily mounted to either side of the vehicle. The Xpanse awning is made up of a 16 × 7-foot (4.9 × 2.1-m) “fabric” of high-efficiency glass-based solar panels. The awning features “bi-facial” solar panels, meaning it captures the energy of the sun from above as well as from below — the underside can capture a surprising amount of energy from reflection off the ground and the RV itself.
