“What we need is the celestial fire to change the flint into the transparent crystal, bright and clear”*…
… or so it used to be. Scientists at Google DeepMind and the Lawrence Berkeley National Laboratory have applied AI to the task– with encouraging results…
Modern technologies from computer chips and batteries to solar panels rely on inorganic crystals. To enable new technologies, crystals must be stable otherwise they can decompose, and behind each new, stable crystal can be months of painstaking experimentation.
… in a paper published in Nature, we share the discovery of 2.2 million new crystals – equivalent to nearly 800 years’ worth of knowledge. We introduce Graph Networks for Materials Exploration (GNoME), our new deep learning tool that dramatically increases the speed and efficiency of discovery by predicting the stability of new materials.
With GNoME, we’ve multiplied the number of technologically viable materials known to humanity. Of its 2.2 million predictions, 380,000 are the most stable, making them promising candidates for experimental synthesis. Among these candidates are materials that have the potential to develop future transformative technologies ranging from superconductors, powering supercomputers, and next-generation batteries to boost the efficiency of electric vehicles.
GNoME shows the potential of using AI to discover and develop new materials at scale. External researchers in labs around the world have independently created 736 of these new structures experimentally in concurrent work. In partnership with Google DeepMind, a team of researchers at the Lawrence Berkeley National Laboratory has also published a second paper in Nature that shows how our AI predictions can be leveraged for autonomous material synthesis.
We’ve made GNoME’s predictions available to the research community. We will be contributing 380,000 materials that we predict to be stable to the Materials Project, which is now processing the compounds and adding them into its online database. We hope these resources will drive forward research into inorganic crystals, and unlock the promise of machine learning tools as guides for experimentation…
GNoME suggests that materials science may be the next frontier to be turbocharged by artificial intelligence (see this earlier example from biotech): “Millions of new materials discovered with deep learning.”

As we drive discovery, we might recall that it was on this date in 1942 that a team of scientists led by Enrico Fermi, working inside an enormous tent on a squash court under the stands of the University of Chicago’s Stagg Field, achieved the first controlled nuclear fission chain reaction… laying the foundation for the atomic bomb and later, nuclear power generation– that’s to say, inaugurating the Atomic Age.

Indeed, exactly 15 years later, on this date in 1957, the world’s first full-scale atomic electric power plant devoted exclusively to peacetime uses, the Shippingport Atomic Power Station, reached criticality; the first power was produced 16 days later, after engineers integrated the generator into the distribution grid of Duquesne Light Company.

The idea that China gives every citizen a “social credit score” continues to capture the horrified imagination of many. But it is more bogeyman than reality. Instead, we should be worrying about other, more invasive surveillance practices – and not just in China, argues MERICS analyst Vincent Brussee…
“What if every action that you took in your life was recorded in a score like it was a video game?” … “If your score drops to 950, you will be subject to re-education.” … “It is the beginning of slavery, complete control, and the disappearance of all freedoms … In China, they call it social credit.” These are just some of the statements made in parliamentary debates in Europe and online commentaries about China’s Social Credit System. Given the vehemence of these views, and the attention they attract, it must have come as a real headscratcher to many when China recently pledged that would ban the use of AI for social scoring.
So, what are the facts relating to China’s Social Credit System (SoCS)? First, a system does exist, but it is very different from what is imagined by many critics outside China. The biggest disconnect is around the notion of scores. Some commentators seem to imagine that a magic algorithm draws from AI cameras and internet surveillance all over the country to calculate a score that determines everyone’s place in society. In reality, the SoCS is not the techno-dystopian nightmare we fear: it is lowly digitalized, highly fragmented, and primarily focuses on businesses. Most importantly, such a score simply does not exist.
… this does not mean that the SoCS is benign. It also does not imply that China’s broader surveillance apparatus is a myth – quite to the contrary. However, public debates typically do not focus on these aspects. Rather, the interest in the system often stems from broader anxieties about digital technologies, as reflected in the UN pledge and similar actions taken by other countries. Often, the SoCS is merely invoked as a metaphor: either to depict some technological threat at home or to portray a techno-dystopian China.
This is symptomatic of a tendency to see China not as a real place with real people, but as an abstract “negative opposite” of “us.” While our discussions on tech in China remain overshadowed by largely fictional scoring, we ignore real threats of surveillance to exactly those people in China. And when we use the SoCS to invoke the image of a technological threat at home, we lose sight of potentially acute technological threats much closer to reality.
In both cases, the real losers are the people that those making the claims say they want to protect…

“The past is obdurate,” Stephen King wrote in his book about a man who goes back in time to prevent the Kennedy assassination. “It doesn’t want to be changed.”
Turns out, King might have been onto something.
Countless science fiction tales have explored the paradox of what would happen if you do something in the past that endangers the future. Perhaps one of the most famous pop culture examples is Back to the Future, when Marty McFly went back in time and accidentally stopped his parents from meeting, putting his own existence in jeopardy.
But maybe McFly wasn’t in much danger after all. According a new paper from researchers at the University of Queensland, even if time travel were possible, the paradox couldn’t actually exist…

As we ponder predestination, we might send cosmological birthday greetings to Enrico Fermi; he was born on this date in 1901. A physicist who is best remembered for (literally) presiding over the birth of the Atomic Age, he was also remarkable as the last “double-threat” in his field: a genius at creating both important theories and elegant experiments. As recently observed, the division of labor between theorists and experimentalists has since been pretty complete.
The novelist and historian of science C. P. Snow wrote that “if Fermi had been born a few years earlier, one could well imagine him discovering Rutherford’s atomic nucleus, and then developing Bohr’s theory of the hydrogen atom. If this sounds like hyperbole, anything about Fermi is likely to sound like hyperbole.”

Quantum computing is all the rage. It seems like hardly a day goes by without some news outlet describing the extraordinary things this technology promises. Most commentators forget, or just gloss over, the fact that people have been working on quantum computing for decades—and without any practical results to show for it.
We’ve been told that quantum computers could “provide breakthroughs in many disciplines, including materials and drug discovery, the optimization of complex manmade systems, and artificial intelligence.” We’ve been assured that quantum computers will “forever alter our economic, industrial, academic, and societal landscape.” We’ve even been told that “the encryption that protects the world’s most sensitive data may soon be broken” by quantum computers. It has gotten to the point where many researchers in various fields of physics feel obliged to justify whatever work they are doing by claiming that it has some relevance to quantum computing.
Meanwhile, government research agencies, academic departments (many of them funded by government agencies), and corporate laboratories are spending billions of dollars a year developing quantum computers. On Wall Street, Morgan Stanley and other financial giants expect quantum computing to mature soon and are keen to figure out how this technology can help them.
It’s become something of a self-perpetuating arms race, with many organizations seemingly staying in the race if only to avoid being left behind. Some of the world’s top technical talent, at places like Google, IBM, and Microsoft, are working hard, and with lavish resources in state-of-the-art laboratories, to realize their vision of a quantum-computing future.
In light of all this, it’s natural to wonder: When will useful quantum computers be constructed? The most optimistic experts estimate it will take 5 to 10 years. More cautious ones predict 20 to 30 years. (Similar predictions have been voiced, by the way, for the last 20 years.) I belong to a tiny minority that answers, “Not in the foreseeable future.” Having spent decades conducting research in quantum and condensed-matter physics, I’ve developed my very pessimistic view. It’s based on an understanding of the gargantuan technical challenges that would have to be overcome to ever make quantum computing work…
