The record for high-temperature superconductivity has been smashed again Chemists found a material that can display superconducting behavior at a temperature warmer than it currently is at the North Pole. The work brings room-temperature superconductivity tantalizingly close. Superconductivity is the weird phenomenon of zero electrical resistance that occurs when some materials are cooled below a
Quantum computers pose a security threat that we’re still totally unprepared for Some US experts think it could take at least 20 years to get quantum-proof encryption widely deployed. The world relies on encryption to protect everything from credit card transactions to databases holding health records and other sensitive information. A new report from the US National Academies of Sciences, Enginee
Your smartphone’s AI algorithms could tell if you are depressed Smartphones that are used to track our faces and voices could also help lower the barrier to mental-health diagnosis and treatment. Depression is a huge problem for millions of people, and it is often compounded by poor mental-health support and stigma. Early diagnosis can help, but many mental disorders are difficult to detect. The m
The clinical trial documents describe a study in which CRISPR is employed to modify human embryos before they are transferred into women’s uteruses. The scientist behind the effort, He Jiankui, did not reply to a list of questions about whether the undertaking had produced a live birth. Reached by telephone, he declined to comment. However, data submitted as part of the trial listing shows that ge
Yoshua Bengio is a grand master of modern artificial intelligence. Alongside Geoff Hinton and Yann LeCun, Bengio is famous for championing a technique known as deep learning that in recent years has gone from an academic curiosity to one of the most powerful technologies on the planet. Deep learning involves feeding data to large neural networks that crudely simulate the human brain, and it has pr
A quantum version of the building block behind neural networks could be exponentially more powerful. Back in 1958, in the earliest days of the computing revolution, the US Office of Naval Research organized a press conference to unveil a device invented by a psychologist named Frank Rosenblatt at the Cornell Aeronautical Laboratory. Rosenblatt called his device a perceptron, and the New York Time
Should a self-driving car kill the baby or the grandma? Depends on where you’re from. The infamous “trolley problem” was put to millions of people in a global study, revealing how much ethics diverge across cultures. In 2014 researchers at the MIT Media Lab designed an experiment called Moral Machine. The idea was to create a game-like platform that would crowdsource people’s decisions on how self
Facebook’s ex security boss: Asking Big Tech to police hate speech is “a dangerous path” Alex Stamos on the risks of giving his former employer and other giant platforms the power to determine what people can—and can’t—say online. Until a few weeks ago, Alex Stamos was Facebook’s chief security officer. He led the hunt for Russian political disinformation on the platform after the 2016 US election
Waymo’s cars drive 10 million miles a day in a perilous virtual world A simulation lets autonomous cars experience situations that are too dangerous to try in reality. You could argue that Waymo, the self-driving subsidiary of Alphabet, has the safest autonomous cars around. It’s certainly covered the most miles. But in recent years, serious accidents involving early systems from Uber and Tesla h
Here’s how China rules using data, AI, and internet surveillance. In 1955, science fiction writer Isaac Asimov published a short story about an experiment in “electronic democracy,” in which a single citizen, selected to represent an entire population, responded to questions generated by a computer named Multivac. The machine took this data and calculated the results of an election that therefore
Evolutionary algorithm outperforms deep-learning machines at video games Neural networks have garnered all the headlines, but a much more powerful approach is waiting in the wings. With all the excitement over neural networks and deep-learning techniques, it’s easy to imagine that the world of computer science consists of little else. Neural networks, after all, have begun to outperform humans in
The Japanese nuclear disaster bathed north America in a radioactive cloud. Now pharmacologists have found the telltale signature in California wine made at the time. Throughout the 1950s, the US, the Soviet Union, and others tested thermonuclear weapons in the Earth’s atmosphere. Those tests released vast quantities of radioactive material into the air and triggered fears that the nuclear reaction
Unlike chess moves, changes to a Rubik’s Cube are hard to evaluate, which is why deep-learning machines haven’t been able to solve the puzzle on their own. Until now. Yet another bastion of human skill and intelligence has fallen to the onslaught of the machines. A new kind of deep-learning machine has taught itself to solve a Rubik’s Cube without any human assistance. The milestone is significant
Researchers have predicted the outcome after simulating the entire soccer tournament 100,000 times. The 2018 soccer World Cup kicks off in Russia on Thursday and is likely to be one of the most widely viewed sporting events in history, more popular even than the Olympics. So the potential winners are of significant interest. One way to gauge likely outcomes is to look at bookmakers’ odds. These co
Computer scientists have found the longest straight line you could sail without hitting land While they were at it, they found the longest straight path you could drive without hitting water. Back in 2012, a curious debate emerged on the discussion website Reddit, specifically on a subreddit called /r/MapPorn. Here the user Kepleronlyknows posted a map of the world purporting to show the longest n
There was no evidence that the disembodied pig brains regained consciousness. However, in what Sestan termed a “mind-boggling” and “unexpected” result, billions of individual cells in the brains were found to be healthy and capable of normal activity. Reached by telephone yesterday, Sestan declined to elaborate, saying he had submitted the results for publication in a scholarly journal and had not
US conservatives spread tweets by Russian trolls over 30 times more often than liberals The first detailed analysis of how misinformation spread through the Twittersphere during the 2016 election also shows that the most retweets of troll content came from Tennessee and Texas. Toward the end of last year, the US Congress released a list of online accounts associated with Internet Research Agency,
If you’re so smart, why aren’t you rich? Turns out it’s just chance. The most successful people are not the most talented, just the luckiest, a new computer model of wealth creation confirms. Taking that into account can maximize return on many kinds of investment. The distribution of wealth follows a well-known pattern sometimes called an 80:20 rule: 80 percent of the wealth is owned by 20 percen
Dueling neural networks. Artificial embryos. AI in the cloud. Welcome to our annual list of the 10 technology advances we think will shape the way we work and live now and for years to come. Every year since 2001 we’ve picked what we call the 10 Breakthrough Technologies. People often ask, what exactly do you mean by “breakthrough”? It’s a reasonable question—some of our picks haven’t yet reached
1. Overestimating and underestimating Roy Amara was a cofounder of the Institute for the Future, in Palo Alto, the intellectual heart of Silicon Valley. He is best known for his adage now referred to as Amara’s Law: We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run. There is a lot wrapped up in these 21 words. An optimist can read it o
First Evidence That Online Dating Is Changing the Nature of Society Dating websites have changed the way couples meet. Now evidence is emerging that this change is influencing levels of interracial marriage and even the stability of marriage itself. Not so long ago, nobody met a partner online. Then, in the 1990s, came the first dating websites. Match.com went live in 1995. A new wave of dating we
The West shouldn’t fear China’s artificial-intelligence revolution. It should copy it. On a tropical island that marks the southern tip of China, a computer program called Lengpudashi is playing one-on-one poker against a dozen people at once, and it’s absolutely crushing them. Lengpudashi, which means “cold poker master” in Mandarin, is using a new artificial-intelligence technique to outbet and

Google’s New Chip Is a Stepping Stone to Quantum Computing Supremacy The search giant plans to reach a milestone in computing history before the year is out. John Martinis has given himself just a few months to reach a milestone in the history of computing. He’s leader of the Google research group working on building astonishingly powerful computer chips that manipulate data using the quirks of qu
No one really knows how the most advanced algorithms do what they do. That could be a problem. Last year, a strange self-driving car was released onto the quiet roads of Monmouth County, New Jersey. The experimental vehicle, developed by researchers at the chip maker Nvidia, didn’t look different from other autonomous cars, but it was unlike anything demonstrated by Google, Tesla, or General Motor
Google Brain Wants Creative AI to Help Humans Make a “New Kind of Art” The search giant’s AI research division has developed a deep-learning tool to produce music and art with humans in the loop. Machine-learning algorithms aren’t likely to put painters or singer-songwriters out of work anytime soon, to judge from their body of work to date. But Google Brain is developing tools that pair artists w
These technologies all have staying power. They will affect the economy and our politics, improve medicine, or influence our culture. Some are unfolding now; others will take a decade or more to develop. But you should know about all of them right now.
