How scientists are embracing NFTs

Posted by in category: cryptocurrencies

The arguments over NFTs in science are similarly heated, with some saying they provide an incentive to showcase science to the public; a new method of fundraising; and even a way for people to earn royalties when pharmaceutical companies buy access to their genomic data. Others say that NFTs — which operate in a similar way to digital cryptocurrencies — are just needless energy pouring into a market bubble that’s sure to burst.

Is a trend of auctioning non-fungible tokens based on scientific data a fascinating art fad, an environmental disaster or the future of monetized genomics?

A New Technique for Seeing Exoplanet Surfaces Based on the Content of their Atmospheres

Posted by in category: space

A new study takes a look at how the presence of a surface can affect an exoplanets atmosphere, giving astrobiologists a way to study exoplanet surfaces without having to “see” them directly.

How to Detect Heat from Extraterrestrial Probes in Our Solar System

We could do it with the James Webb Space Telescope—but we’d also need to return to the unfiltered curiosity we had as teenagers.

This Is the First Fusion Power Plant to Generate Net Electricity

Posted by in categories: military, nuclear energy

Here’s the secret to the self-sustaining tokamak concept.

Could the future of nuclear fusion be a much smaller, self-sustaining tokamak reactor? Researchers at the General Atomics DIII-D National Fusion Facility, the largest nuclear fusion research facility in the U.S., think so. The secret is the pressurized plasma.

The scientists from DIII-D have designed a full “compact nuclear fusion plant” concept and detailed the plans in a new paper in Nuclear Fusion. In simulations, their 8-meter-wide pressurized plasma fusion concept is powerful enough to generate 200 megawatts (MW) of net electricity after the energy cost of the fusion itself.

Light cages could give quantum-information networks a boost

Posted by in categories: computing, particle physics, quantum physics

A new on-chip device that is very good at mediating interactions between light and atoms in a vapour has been developed by researchers in Germany and the UK. Flavie Davidson-Marquis at Humboldt University of Berlin and colleagues call their device a “quantum-optically integrated light cage” and say that it could be used for wide range of applications in quantum information technology.

Hybrid quantum photonics is a rapidly growing area of research that integrates different optical systems within miniaturized devices. One area of interest is the creation of devices for the control, storage and retrieval of the quantum states of light using individual atoms. This is usually done by integrating on-chip photonic devices with miniaturized cells containing warm vapours of alkali atoms. However, this approach faces challenges due to inefficient vapour filling times, high losses of quantum information near cell surfaces and limited overlaps between the wavelengths of light used in optical circuits and the wavelengths of atomic transitions.

Mathematicians welcome computer-assisted proof in grand unification theory

Posted by in categories: computing, mathematics

Once researchers have done the hard work of translating a set of mathematical concepts into a proof assistant, the program generates a library of computer code that can be built on by other researchers and used to define higher-level mathematical objects. In this way, proof assistants can help to verify mathematical proofs that would otherwise be time-consuming and difficult, perhaps even practically impossible, for a human to check.

Proof assistants have long had their fans, but this is the first time that they have played a major role at the cutting edge of a field, says Kevin Buzzard, a mathematician at Imperial College London who was part of a collaboration that checked Scholze and Clausen’s result. “The big remaining question was: can they handle complex mathematics?” Says Buzzard. “We showed that they can.”

And it all happened much faster than anyone had imagined. Scholze laid out his challenge to proof-assistant experts in December 2020, and it was taken up by a group of volunteers led by Johan Commelin, a mathematician at the University of Freiburg in Germany. On 5 June — less than six months later — Scholze posted on Buzzard’s blog that the main part of the experiment had succeeded. “I find it absolutely insane that interactive proof assistants are now at the level that, within a very reasonable time span, they can formally verify difficult original research,” Scholze wrote.

Young Chaotic Star System Reveals Secrets of Planet Formation

Posted by in category: cosmology

New observations of young stellar object Elias 2–27 confirm gravitational instabilities and planet-forming disk mass as key to formation of giant planets.

A team of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2–27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation. The results of the research are published today (June 17, 2021) in two papers in The Astrophysical Journal.

Protoplanetary disks — planet-forming disks made of gas and dust that surround newly formed young stars — are known to scientists as the birthplace of planets. The exact process of planet formation, however, has remained a mystery. The new research, led by Teresa Paneque-Carreño — a recent graduate of the Universidad de Chile and PhD student at the University of Leiden and the European Southern Observatory, and the primary author on the first of the two papers — focuses on unlocking the mystery of planet formation.
