Roscosmos wants guarantee from the UK satellite company it will not use its satellites for military purposes.
Meta, formerly Facebook, has said that its grand ambition of building the ultimate “metaverse” won’t be possible if there aren’t drastic improvements in today’s telecoms networks.
The metaverse is a buzzword that’s being hyped up as the next big thing in tech. Broadly speaking, the concept refers to a seamless virtual world where people can work, shop and play with their colleagues, friends and family.
Dan Rabinovitsj, VP of connectivity at Meta, told CNBC at the Mobile World Congress tech event Monday that home networks and cellular networks aren’t yet ready for the metaverse.

As hard as diamond and as flexible as plastic, highly sought-after diamond nanothreads would be poised to revolutionize our world—if they weren’t so difficult to make.
Recently, a team of scientists led by Carnegie’s Samuel Dunning and Timothy Strobel developed an original technique that predicts and guides the ordered creation of strong, yet flexible, diamond nanothreads, surmounting several existing challenges. The innovation will make it easier for scientists to synthesize the nanothreads—an important step toward applying the material to practical problems in the future. The work was recently published in the Journal of the American Chemical Society.
Diamond nanothreads are ultra-thin, one-dimensional carbon chains, tens of thousands of times thinner than a human hair. They are often created by compressing smaller carbon-based rings together to form the same type of bond that makes diamonds the hardest mineral on our planet.
Circa 2021
Small, affordable, ‘plug-and-play’ quantum computing is one step closer. An Australian startup has won $13 million to make its diamond-based computing cores shine. Now it needs to grow.
ANU research spinoff Quantum Brilliance has found a way to use synthetic diamonds to drive quantum calculations. Now it’s on a five-year quest to produce commercially viable Quantum Accelerators. The goal is a card capable of being plugged into any existing computer system similar to the way graphics cards are now.

The trial started in March 2021 and was completed in early 2022.
Russia’s space agency is refusing to launch OneWeb satellites part-owned by the UK government.
Schran agrees. “This new mechanism of friction is definitely very interesting and exciting,” he says. “But what is missing in my opinion, is a clear benchmark measurement.” Quantifying, for instance, how friction changes based on water’s interaction with single versus multiple layers of carbon atoms could go a long way to fully verifying the new theory, which predicts that greater numbers of electrons in the multilayered carbon will boost friction.
The study team is already progressing along this path and dreaming of what lies beyond. They are hoping to eventually test their theory with flowing liquids other than water, and nanotubes composed of elements besides carbon. In such cases, molecules in the liquid and the electrons within nanotube walls would follow different patterns of interaction, possibly leading to changes in the degree of quantum friction. Lydéric Bocquet says that it may even be possible to control the amount of friction a flowing liquid experiences by constructing nanotubes with electron behavior explicitly in mind.
The new study sets the stage for years of complex exploration by experimental and theoretical physicists alike and, according to Kavokine, also signals a fundamental shift in how physicists should think about friction. “Physicists have long thought that it is different at the nanoscale, but this difference was not so obvious to find and describe,” he says. “They were dreaming about some quantum behavior arising at these scales—and now we have shown how it does.”
Flipping the fuses ends the story.
Intel is now disabling support for AVX-512 instructions in its Alder Lake processors by fusing it off inside the silicon.
