Scientists in South Africa are warning of a new strain of COVID-19. The variant, which is yet to be named, appears to have a high number of mutations, and there’s a possibility it could be able to evade our immune response and be even more transmissible.
At first, health officials thought they were seeing a small cluster of outbreaks in South Africa’s most populous province. But after examining specimens, they realized they were dealing with something far more serious — a new variant that could be the hardest yet to contain.
Officials are worried that the new variant, known simply as B.1.1.529, could quickly spread through the country and beyond. Only about 35% of adults in South Africa are fully vaccinated, and the rate of vaccination has slowed. And given the findings so far, even current vaccines may not be enough to stop it.
Several countries, including the UK and Germany have announced a ban on flights from South Africa and five neighboring countries as cases of the new variant have already appeared in Botswana and in Hong Kong. No matter where the variant started, it could quickly become a global problem.

Early-career nuclear physicists show that a better understanding of how neutrinos interact with matter is needed to make the most of upcoming experiments.

Neutrinos may be the key to finally solving a mystery of the origins of our matter-dominated universe, and preparations for two major, billion-dollar experiments are underway to reveal the particles’ secrets. Now, a team of nuclear physicists have turned to the humble electron to provide insight for how these experiments can better prepare to capture critical information. Their research, which was carried out at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility and recently published in Nature, reveals that major updates to neutrino models are needed for the experiments to achieve high-precision results.

Neutrinos are ubiquitous, generated in copious numbers by stars throughout our universe. Though prevalent, these shy particles rarely interact with matter, making them very difficult to study.

After three years of intensive research and countless test flights in BMW’s horizontal wind tunnel, Salzmann and the wingsuit completed the maiden flight over the picturesque mountains of Austria last week. The 33-year-old was dropped by helicopter at just shy of 10,000 feet alongside two other fliers sporting conventional wingsuits. BMW says the electric wingsuit enabled Salzmann to accelerate faster than his mates at a peak speed of 186 mph. (Normal wingsuit operators typically reach horizontal speeds around 62 mph.)

The e-wingsuit is built upon BMW i EV technology and powered by a chest-mounted rig. It offers 15 kW of grunt that’s split between two 7.5 kW carbon impellers. The impellers spin at a speed of 25,000 rpm and produce thrust for up to five minutes. The aim of the electric wingsuit is to increase performance and eventually allow for longer distances to be covered.

The Indian and Japanese space agencies are planning a joint mission to the Moon, that is meant to explore the Polar region.

The mission, which will be known as Lunar Polar Exploration Mission (LUPEX), will feature an Indian lunar lander and a Japanese rover.

Dr Hiroshi Yamakawa, President, Japan Aerospace Exploration Agency (JAXA) revealed this and Japan’s future mission plans, at the Sydney Dialogue, an initiative by the Australian Strategic Policy Institute.

At Europe’s Spaceport near Kourou in French Guiana, technicians are busy getting the James Webb Space Telescope (JWST) ready for launch. The observatory arrived at the facility on Oct. 12^th and was placed inside the upper stage of the Ariane 5 rocket that will carry it to space on Nov. 11^th. The upper stage was then hoisted high above the core stage and boosters so that a team of engineers could integrate them.

Unfortunately, an “incident” occurred shortly after when the engineers attempted to attach the upper stage to the launch vehicle adapter (LVA) to the launch vehicle. According to a NASA Blogs post, the incident involved the sudden release of a clamp band (which secures the JWST to the LVA), which sent vibrations throughout the observatory. According to NASA, this incident could push the JWST’s launch date (slated for Dec. 18th) to Dec. 22nd.

A NASA-led anomaly review board was immediately convened to investigate the unexpected development and recommend how to proceed. The board recommended that additional testing be instituted to “determine with certainty” that the incident did not damage any components. NASA also indicated that it and its mission partners would provide an update when the testing is completed, which is expected to be by the end of this week.

Mica is Microsoft’s new transparency effect for Windows 11. It is similar to Acrylic but optimised for performance by only sampling from your wallpaper rather than the app below you.

Microsoft has been rolling out the new look to more and more native apps, and now Office Insiders and Beta users are reporting that the effect is also showing up in their apps.

It’s a cool concept; the blades cant get caught, or stuck, or broken. but, it’s pretty loud, there’s no audio in the demo videos. Still, i think a flying drone would be superior for exploring underground structurers and caves, til it hit a door or something anyways. Anyhow, i think the flight system should focus on some kind of a total silence ion drive.

It was three years ago that we first heard about the Cleo, a robust, donut-shaped prototype drone made by Cleo Robotics. Well, its successor is now commercially available, under the new (and apt) name of the Dronut X1.

Physicists have created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for quantum computing and advance research into unconventional superconductivity and quantum criticality.

The researchers showed that by starting from seemingly common materials, a radically new quantum state of matter can appear. The discovery emerged from their efforts to create a quantum spin liquid which they could use to investigate emergent quantum phenomena such as gauge theory. This involves fabricating a single layer of atomically thin tantalum disulfide, but the process also creates islands that consist of two layers.
