Magnets and superconductors don’t normally get along, but a new study shows that ‘magic-angle’ graphene is capable of producing both superconductivity and ferromagnetism, which could be useful in quantum computing.

When two sheets of the carbon nanomaterial graphene are stacked together at a particular angle with respect to each other, it gives rise to some fascinating physics. For instance, when this so-called “magic-angle graphene” is cooled to near absolute zero 0, it suddenly becomes a superconductor, meaning it conducts electricity with zero resistance.

Now, a research team from Brown University has found a surprising new phenomenon that can arise in magic-angle graphene. In research published in the journal Science, the team showed that by inducing a phenomenon known as spin-orbit coupling, magic-angle graphene becomes a powerful ferromagnet.

Structure may reveal conditions needed for high-temperature superconductivity.

When two sheets of graphene are stacked atop each other at just the right angle, the layered structure morphs into an unconventional superconductor, allowing electric currents to pass through without resistance or wasted energy.

Viruses can be wily adapters, changing their identities to find new hosts and thwart efforts to stop them. That’s why University of Wisconsin-Madison researchers and their collaborators are making progress toward developing universal vaccines against some the planet’s most harmful pathogens, including the virus family responsible for the COVID-19 pandemic.

Last fall, the National Institutes of Health announced it was investing in three teams working to develop a vaccine that would simultaneously work against a broad range of coronaviruses. Among them is a research collaboration, the Pan-Coronavirus Vaccine consortium, led by UW-Madison School of Veterinary Medicine Professor of Pathobiological Sciences Yoshihiro Kawaoka.

“This pan-coronavirus vaccine is basically preparing for the future,” Kawaoka says.

And it can balance perfectly on power lines.

Scientists at UC Berkeley developed an experimental drone called the Midair Reconfigurable Quadcopter. As the name implies, the drone can shape-shift in midair, a report from NewAtlas reveals.

Musicians have been experimenting with artificial intelligence for a few years now. For example, in 2019, an AI trained on Schubert’s music completed his Unfinished Symphony and last October the Beethoven Orchestra in Bonn performed an AI-generated version of Beethoven’s last symphony.

But what are the limits of AI music? Can an AI really be considered creative? And is it possible for an AI to improvise with musicians live on stage?

‘Bringing archaeological perspectives to an active space domain’.

While most people naturally associate archaeology with ancient remains and treasured artifacts, one group of scientists is breaking that mold by kickstarting the first-ever archaeological project aboard the International Space Station (ISS), a press statement reveals.

It is the first time such a project has taken place aboard any space habitat and its aim is to catalog how humans adapt their living behaviors while in space for months at a time. As a point of reference, the longest stay aboard the ISS so far is NASA astronaut Christina Koch’s 328-day stay, which ended last year.

A common concern surrounding automation in recent years is that it will result in widescale job losses as the work previously done by people is taken over by technology. Of course, the reality doesn’t really support this narrative, and indeed, companies that invest in technology often end up employing more people as a result of the improvement in their fortunes heralded by the investment.

The leadership team of the fintech company Kashat highlight the reality of investing in technology. They reveal that microfinance has traditionally been highly labor intensive, with many of the skills the same as those used in the sector for years. With the introduction of AI, new skills have been introduced into the underwriting process in order to serve at scale, while enabling employees to further expand their skillset and become even more valuable in the future.

The impact of this distinction is clearly visible in the growth rates across the sector, with those more tech-enabled firms growing far faster, and therefore employing more people, than their more traditional peers.

Last week saw an announcement that Optimus Ride, an autonomous shuttle company in Boston was purchased in an acqui-hire by Magna, the Ontario based Tier One Automotive company. In an acqui-hire, the company has generally failed, but a buyer pays to pick up the assets and to hire the team, which took time to create. Usually it’s only enough to reward the preferred investors, the team gets options in their new employer.

Optimus Ride built a shuttle on top of the GEM 6-seater electric shuttle platform, adding sensors and their autonomy tools. It evolved out of MIT.

Also announced as shutting its doors was Local Motors, maker of the Olli shuttle. Local Motors began with a focus on 3D printing to make smaller volume vehicles. The started with the Rally Fighter, a vehicle that was crowd designed after contests. Over time, founder Jay Rogers believed that 3D printing could bring a vehicle to production faster and at lower cost than conventional methods than conventional methods, and entered the Shuttle market, partnering with various partners to make them autonomous. Recently, we reported how an Olli shuttle in Whitby, Ontario had a crash resulting in serious injuries. Early reports suggested it was in autonomous mode, but it was later revealed it was being manually driven at the time. That made it mostly a non-story, but the real story of Olli did not go so well, either.
