Scientists in Chicago are trying to create the embryo of the first quantum internet. If they succeed, the researchers will produce one, 30-mile piece of a far more secure communications system with the power of fast quantum computing. From a report: The key was the realization of an unused, 30-mile-long fiber optic link connecting three Chicago-area research institutions -- Argonne National Lab, Fermi Lab and the University of Chicago. This led to the idea to combine efforts and use the link for what they call the Chicago Quantum Exchange. David Awschalom, an Argonne scientist and University of Chicago professor who is the project's principal investigator, tells Axios that the concept is difficult to grasp, even for experts. MIT Technology Review elaborates: The QKD approach used by Quantum Xchange works by sending an encoded message in classical bits while the keys to decode it are sent in the form of quantum bits, or qubits. These are typically photons, which travel easily along fiber-optic cables. The beauty of this approach is that any attempt to snoop on a qubit immediately destroys its delicate quantum state, wiping out the information it carries and leaving a telltale sign of an intrusion. The initial leg of the network, linking New York City to New Jersey, will allow banks and other businesses to ship information between offices in Manhattan and data centers and other locations outside the city.

However, sending quantum keys over long distances requires "trusted nodes," which are similar to repeaters that boost signals in a standard data cable. Quantum Xchange says it will have 13 of these along its full network. At nodes, keys are decrypted into classical bits and then returned to a quantum state for onward transmission. In theory, a hacker could steal them while they are briefly vulnerable.

Like many people, Alex Stamos, former Facebook chief security officer, thinks tech platforms like Facebook and Google have too much power. But he doesn't agree with the calls to break them up. And he argues that the very people who say Facebook and Google are too powerful are giving them more power by insisting they do more to control hate speech and propaganda. From a report: "That's a dangerous path," he warns. If democratic countries make tech firms impose limits on free speech, so will autocratic ones. Before long, the technology will enable "machine-speed, real-time moderation of everything we say online." In attempting to rein in Big Tech, we risk creating Big Brother. So what's the solution? I spoke to Stamos at his Stanford office to find out.

Technology Review: So is the disinformation/propaganda problem mostly solved?
Stamos: In a free society, you will never eliminate that problem. I think the most important thing [in the US] is the advertising transparency. With or without any foreign interference, the parties, the campaigns, the PACs [political action committees] here in the US are divvying up the electorate into tiny little buckets, and that is a bad thing. Transparency is a good start. The next step we need is federal legislation to put a limit on ad targeting. There are thousands of companies in the internet advertising ecosystem. Facebook, Google, and Twitter are the only ones that have done anything, because they have gotten the most press coverage and the most pressure from politicians. So without legislation we're just going to push all of the attackers into the long tail of advertising, to companies that don't have dedicated teams looking for Russian disinformation groups.

Technology Review: Facebook has been criticized over Russian political interference both in the US and in other countries, the genocide in Myanmar, and a lot of other things. Do you feel Facebook has fully grasped the extent of its influence and its responsibility?
Stamos: I think the company certainly understands its impact. The hard part is solving it. Ninety percent of Facebook users live outside the United States. Well over half live in either non-free countries or democracies without protection for speech. One of the problems is coming up with solutions in these countries that don't immediately go to a very dark place [i.e., censorship]. Another is figuring out what issues to put engineering resources behind. No matter how big a company is, there are only a certain number of problems you [can tackle]. One of the problems that companies have had is that they're in a firefighting mode where they jump from emergency to emergency. So as they staff up that gets better, but we also need a more informed external discussion about the things we want the companies to focus on -- what are the problems that absolutely have to be solved, and what aren't. You mentioned a bunch of a problems that are actually very different, but people blur them all together.

Technology Review: How do you regulate in a world in which tech is advancing so fast while regulation moves so slowly? How should a society set sensible limits on what tech companies do?
Stamos: But right now, society is not asking for limits on what they do. It's asking that tech companies do more. And I think that's a dangerous path. In all of the problems you mentioned -- Russian disinformation, Myanmar -- what you're telling these companies is, "We want you to have more power to control what other people say and do." That's very dangerous, especially with the rise of machine learning. Five or ten years from now, there could be machine-learning systems that understand human languages as well as humans. We could end up with machine-speed, real-time moderation of everything we say online. So the powers we grant the tech companies right now are the powers those machines are going to have in five years.

Improvements in CGI mean neither age nor death need stop some performers from working. From a report: From Carrie Fisher in Rogue One: A Star Wars Story to Paul Walker in the Fast & Furious movies, dead and magically "de-aged" actors are appearing more frequently on movie screens. Sometimes they even appear on stage: next year, an Amy Winehouse hologram will be going on tour to raise money for a charity established in the late singer's memory. Some actors and movie studios are buckling down and preparing for an inevitable future when using scanning technology to preserve 3-D digital replicas of performers is routine. Just because your star is inconveniently dead doesn't mean your generation-spanning blockbuster franchise can't continue to rake in the dough. Get the tech right and you can cash in on superstars and iconic characters forever.

[...] For celebrities, these scans are a chance to make money for their families post mortem, extend their legacy -- and even, in some strange way, preserve their youth. Visual-effects company Digital Domain -- which has worked on major pictures like Avengers: Infinity War and Ready Player One -- has also taken on individual celebrities as clients, though it hasn't publicized the service. "We haven't, you know, taken out any ads in newspapers to 'Save your likeness,'" says Darren Hendler, director of the firm's Digital Humans Group. The suite of services that the company offers actors includes a range of different scans to capture their famous faces from every conceivable angle -- making it simpler to re-create them in the future. Using hundreds of custom LED lights arranged in a sphere, numerous images can be recorded in seconds capturing what the person's face looks like lit from every angle -- and right down to the pores.

A startup founded in Palo Alto, California, by a trio of doctors, including the former director of the US National Institute of Mental Health, is trying to prove that our obsession with the technology in our pockets can help treat some of today's most intractable medical problems: depression, schizophrenia, bipolar disorder, post-traumatic stress disorder, and substance abuse. MIT Technology Review: Mindstrong Health is using a smartphone app to collect measures of people's cognition and emotional health as indicated by how they use their phones. Once a patient installs Mindstrong's app, it monitors things like the way the person types, taps, and scrolls while using other apps. This data is encrypted and analyzed remotely using machine learning, and the results are shared with the patient and the patient's medical provider.

The seemingly mundane minutiae of how you interact with your phone offers surprisingly important clues to your mental health, according to Mindstrong's research -- revealing, for example, a relapse of depression. With details gleaned from the app, Mindstrong says, a patient's doctor or other care manager gets an alert when something may be amiss and can then check in with the patient by sending a message through the app (patients, too, can use it to message their care provider).

MIT Technology Review recently discussed new attempts to replace the standard 'QWERY' keyboard layout, including Tap, "a one-handed gadget that fits over your fingers like rubbery brass knuckles and connects wirelessly to your smartphone." It's supposed to free you from clunky physical keyboards and act as a go-anywhere typing interface. A promotional video shows smiling people wearing Tap and typing with one hand on a leg, on an arm, and even (perhaps jokingly) on some guy's forehead... But when I tried it, the reality of using Tap was neither fun nor funny. Unlike a conventional QWERTY keyboard, Tap required me to think a lot, because I had to tap my fingers in not-very-intuitive combinations to create letters: an A is your thumb, a B is your index finger and pinky, a C is all your fingers except the index.
The article also acknowledges the Dvorak Simplified Keyboard layout and other alternatives like the one-handed Twiddler keyboard, but argues that "neither managed to dent QWERTY's dominance." [W]hat if the future is no input interface at all? Neurable is a startup in Cambridge, Massachusetts, that's working on a way to type simply by thinking. It uses an electrode-dotted headband connected to a VR headset to track brain activity. Machine learning helps figure out what letter you're trying to select and anticipate which key you'll want next. After you select several keys, it can fill in the rest of the word, says cofounder and CEO Ramses Alcaide....

Then there's the device being built over at CTRL-Labs: an armband that detects the activity of muscle fibers in the arm. One use could be to replace gaming controllers. For another feature in the works, algorithms use the data to figure out what it is that your hands are trying to type, even if they're barely moving. CEO and cofounder Thomas Reardon, who previously created Microsoft's Internet Explorer, says this too is a neural interface, of a sort. Whether you're typing or dictating, you're using your brain to turn muscles on and off, he points out.
While a developer version will be shipped this year, Reardon "admits that it is still not good enough for him to toss his trusty mid-'80s IBM Model M keyboard, which he says still 'sounds like rolling thunder' when he types." But do any Slashdot readers have their own suggestions or experiences to share?

Can anything replace 'QWERTY' keyboards?

"The UK Parliament caused a bit of a stir this week with the news that it would play host to its first non-human witness," reports The Verge. "A press release from one of Parliament's select committees (groups of MPs who investigate an issue and report back to their peers) said it had invited Pepper the robot to 'answer questions' on the impact of AI on the labor market." From the report: "Pepper is part of an international research project developing the world's first culturally aware robots aimed at assisting with care for older people," said the release from the Education Committee. "The Committee will hear about her work [and] what role increased automation and robotics might play in the workplace and classroom of the future." It is, of course, a stunt.

As a number of AI and robotics researchers pointed out on Twitter, Pepper the robot is incapable of giving such evidence. It can certainly deliver a speech the same way Alexa can read out the news, but it can't formulate ideas itself. As one researcher told MIT Technology Review, "Modern robots are not intelligent and so can't testify in any meaningful way." Parliament knows this. In an email to The Verge, a media officer for the Education Committee confirmed that Pepper would be providing preprogrammed answers written by robotics researchers from Middlesex University, who are also testifying on the same panel. "It will be clear on the day that Pepper's responses are not spontaneous," said the spokesperson. "Having Pepper appear before the Committee and the chance to question the witnesses will provide an opportunity for members to explore both the potential and limitations of such technology and the capabilities of robots." MP Robert Halfon, the committee's chair, told education news site TES that inviting Pepper was "not about someone bringing an electronic toy robot and doing a demonstration" but showing the "potential of robotics and artificial intelligence." He added: "If we've got the march of the robots, we perhaps need the march of the robots to our select committee to give evidence."

DARPA, the research arm of the U.S. military, has a new Machine Common Sense (MCS) program that will run a competition that asks AI algorithms to make sense of questions with common sense answers. For example, here's one of the questions: "A student puts two identical plants in the same type and amount of soil. She gives them the same amount of water. She puts one of these plants near a window and the other in a dark room. The plant near the window will produce more (A) oxygen (B) carbon dioxide (C) water." MIT Technology Review reports: A computer program needs some understanding of the way photosynthesis works in order to tackle the question. Simply feeding a machine lots of previous questions won't solve the problem reliably. These benchmarks will focus on language because it can so easily trip machines up, and because it makes testing relatively straightforward. Etzioni says the questions offer a way to measure progress toward common-sense understanding, which will be crucial. [...] Previous attempts to help machines understand the world have focused on building large knowledge databases by hand. This is an unwieldy and essentially never-ending task. The most famous such effort is Cyc, a project that has been in the works for decades. "The absence of common sense prevents an intelligent system from understanding its world, communicating naturally with people, behaving reasonably in unforeseen situations, and learning from new experiences,"https://www.darpa.mil/ Dave Gunning, a program manager at DARPA, said in a statement issued this morning. "This absence is perhaps the most significant barrier between the narrowly focused AI applications we have today and the more general AI applications we would like to create in the future."

XxtraLarGe shares a report: Wind power is booming in the United States. It's expanded 35-fold since 2000 and now provides 8% of the nation's electricity. The US Department of Energy expects wind turbine capacity to more than quadruple again by 2050. But a new study by a pair of Harvard researchers finds that a high amount of wind power could mean more climate warming, at least regionally and in the immediate decades ahead. The paper raises serious questions about just how much the United States or other nations should look to wind power to clean up electricity systems. The study, published in the journal Joule, found that if wind power supplied all US electricity demands, it would warm the surface of the continental United States by 0.24 C. That could significantly exceed the reduction in US warming achieved by decarbonizing the nation's electricity sector this century, which would be around 0.1 C. "If your perspective is the next 10 years, wind power actually has -- in some respects -- more climate impact than coal or gas," coauthor David Keith, a professor of applied physics and public policy at Harvard, said in a statement. "If your perspective is the next thousand years, then wind power is enormously cleaner than coal or gas."

An anonymous reader quotes a report from MIT Technology Review: Iron Ox isn't like most robotics companies. Instead of trying to flog you its technology, it wants to sell you food. As the firm's cofounder Brandon Alexander puts it: "We are a farm and will always be a farm." But it's no ordinary farm. For starters, the company's 15 human employees share their work space with robots who quietly go about the business of tending rows and rows of leafy greens. Today Iron Ox is opening its first production facility in San Carlos, near San Francisco. The 8,000-square-foot indoor hydroponic facility -- which is attached to the startup's offices -- will be producing leafy greens at a rate of roughly 26,000 heads a year. That's the production level of a typical outdoor farm that might be five times bigger. The opening is the next big step toward fulfilling the company's grand vision: a fully autonomous farm where software and robotics fill the place of human agricultural workers, which are currently in short supply. Iron Ox uses software, dubbed "The Brain," to watch over the farm and monitor nitrogen levels, temperature, and robot location. Alexander hopes to automative every process of the farm, but human workers are currently needed to help with seeding and processing the crops. He cites the shortage of agricultural workers and the distances that fresh product currently has to be shipped for reasons why we need automated farming.

"The problem with the indoor [farm] is the initial investment in the system," says Yiannis Ampatzidis, an assistant professor of agricultural engineering at the University of Florida. "You have to invest a lot up front. A lot of small growers can't do that." Currently, Iron Ox is sending the food it produces to a local food bank and to the company salad bar.

Transatomic Power, an MIT spinout that drew wide attention and millions in funding, is shutting down almost two years after the firm backtracked on bold claims for its design of a molten-salt reactor. From a report: The company, founded in 2011, plans to announce later today that it's winding down. Transatomic had claimed its technology could generate electricity 75 times more efficiently than conventional light-water reactors, and run on their spent nuclear fuel. But in a white paper published in late 2016, it backed off the latter claim entirely and revised the 75 times figure to "more than twice," a development first reported by MIT Technology Review. Those downgrades forced the company to redesign its system. That delayed plans to develop a demonstration reactor, pushing the company behind rival upstarts like TerraPower and Terrestrial Energy, says Leslie Dewan, the company's cofounder and chief executive. The longer timeline and reduced performance advantage made it harder to raise the necessary additional funding, which was around $15 million. "We weren't able to scale up the company rapidly enough to build a reactor in a reasonable time frame," Dewan says.

According to Engadget, the California Senate has sent Governor Jerry Brown draft legislation that would require manufacturers to either have to use unique preprogrammed passwords or make you change the credentials the first time you use it. "Companies will also have to 'equip the device with a reasonable security feature or features that are appropriate to the nature and function of the device,'" reports Engadget. From the report: If Brown signs the bill into law, it will take effect at the beginning of 2020. But critics claim the wording is vague and doesn't go far enough in ensuring manufacturers don't include unsecured features. "It's like dieting, where people insist you should eat more kale, which does little to address the problem you are pigging out on potato chips," Robert Graham of Errata Security said in a blog post. "The key to dieting is not eating more but eating less." Given the huge number of connected devices available, it's also not clear how the state plans to enforce and regulate the rules.

China might be at loggerheads with the United States over trade, but it is calling for a friendlier approach to the development of artificial intelligence. From a report: Speaking at the World Artificial Intelligence Conference in Shanghai this week, China's vice premier, Liu He, said that AI would depend heavily on international cooperation. "We're hoping that all countries, as members of the global village, will be inclusive and support each other so that we can respond to the double-edged-sword effect of new technologies," He said through a translator. "AI represents a new era. Cross-national and cross-discipline cooperation is inevitable."

President Xi Jinping delivered a similar message in a letter presented at the same conference. Xi said that China would "share results with other countries in the field of artificial intelligence." He also called for collaboration between nations on AI topics such as ethics, law, governance, and security. This new, softer approach to artificial intelligence comes just over a year after the Chinese government announced an ambitious and aggressive AI plan. This blueprint called for Chinese AI researchers to lead the world by 2030, and for domestic companies to build an industry worth more than $150 billion. China's tech industry has already embraced machine learning and AI at an impressive rate.

Rachel Metz reports via MIT Technology Review: Imagine a box, similar to a Wi-Fi router, that sits in your home and tracks all kinds of physiological signals as you move from room to room: breathing, heart rate, sleep, gait, and more. Dina Katabi, a professor of electrical engineering and computer science at MIT, built this box in her lab. And in the not-so-distant future, she believes, it will be able to replace the array of expensive, bulky, uncomfortable gear we currently need to get clinical data about the body. Speaking at MIT Technology Review's EmTech conference in Cambridge, Massachusetts, on Wednesday, Katabi said the box she's been building for the last several years takes advantage of the fact that every time we move -- even if it's just a teeny, tiny bit, such as when we breathe -- we change the electromagnetic field surrounding us.

Her device transmits a low-power wireless signal throughout a space the size of a one- or two-bedroom apartment (even through walls), and the signal reflects off people's bodies. The device then uses machine learning to analyze those reflected signals and extract physiological data. So far, it has been installed in over 200 homes of both healthy people and those with conditions like Parkinson's, Alzheimer's, depression, and pulmonary diseases, she said. Katabi cofounded a startup called Emerald Innovations to commercialize the technology and has already made the device available to biotech and pharmaceutical companies for studies.

Bruce Schneier argues that governments must step in now to force companies developing connected gadgets to make security a priority rather than an afterthought. Schneier made these arguments in his new book titled, Click Here to Kill Everybody which is on sale now. Here's an excerpt from his interview with MIT Technology Review: Technology Review: So what do we need to do to make the Internet+ era safer?
Schneier: There's no industry that's improved safety or security without governments forcing it to do so. Again and again, companies skimp on security until they are forced to take it seriously. We need government to step up here with a combination of things targeted at firms developing internet-connected devices. They include flexible standards, rigid rules, and tough liability laws whose penalties are big enough to seriously hurt a company's earnings.

Technology Review: But won't things like strict liability laws have a chilling effect on innovation?
Schneier: Yes, they will chill innovation -- but that's what's needed right now! The point is that innovation in the Internet+ world can kill you. We chill innovation in things like drug development, aircraft design, and nuclear power plants because the cost of getting it wrong is too great. We're past the point where we need to discuss regulation versus no-regulation for connected things; we have to discuss smart regulation versus stupid regulation.

Technology Review: There's a fundamental tension here, though, isn't there? Governments also like to exploit vulnerabilities for spying, law enforcement, and other activities.
Schneier: Governments are certainly poachers as well as gamekeepers. I think we'll resolve this long-standing tension between offense and defense eventually, but it's going to be a long, hard slog to get there.

An anonymous reader quotes a report from MIT Technology Review: David Anderson at Rydberg Technologies in Ann Arbor, Michigan, and a couple of colleagues, have reinvented the antenna from scratch. Their new device works in an entirely different way from conventional antennas, using a laser to measure the way radio signals interact with certain types of atoms. The secret sauce in the new device is Rydberg atoms. These are cesium atoms in which the outer electrons are so excited that they orbit the nucleus at great distance. At these distances, the electrons' potential energy levels are extremely closely spaced, and this gives them special properties. Indeed, any small electric field can nudge them from one level to another. Radio waves consist of alternating electric fields that readily interact with any Rydberg atoms they come across. This makes them potential sensors.

But how to detect this interaction? A gas made of Rydberg atoms has another property that turns out to be useful -- it can be made transparent by a laser tuned to a specific frequency. This laser essentially saturates the gas's ability to absorb light, allowing another laser beam to pass through it. However, the critical frequency at which this happens depends crucially on the properties of the Rydberg atoms in the gas. When these atoms interact with radio waves, the critical frequency changes in response. That's the basis of the radio detection. Anderson and co create a gas of cesium atoms excited into Rydberg states. They then use a laser tuned to a specific frequency to make the gas transparent. Finally, they shine a second laser through the gas and measure how much light is absorbed, to see how the transparency varies with ambient radio waves. The signal from a simple light-sensitive photodiode then reveals the way the radio signals are frequency modulated or amplitude modulated. The atomic radio can detect a huge range of signals -- over four octaves from the C band to the Q band, or wavelengths from 2.5 to 15 centimeters. It also should be less insensitive to electromagnetic interference due to its lack of conventional radio circuitry. "The atomic radio wave receiver operates by direct real-time optical detection of the atomic response to AM and FM baseband signals, precluding the need for traditional de-modulation and signal-conditioning electronics," say Anderson and co.

It's using lasers to power the aerial machines. An anonymous reader writes: According to New Scientist [paywalled], the US Army is firing lasers at photovoltaic cells on drones to deliver power from a distance. Eventually they hope to power the devices from 500 meters away. How it works: The method is similar to the way University of Washington researchers are powering their mini insect robots. The process creates a lot of heat, which could risk melting the drone. And lasers come with additional risks.

Packing more energy into batteries is the key to delivering electric cars with longer range, smartphones that can last days -- and cheaper electronic products all around. Lithium-oxygen batteries represent one of the more promising paths toward that end. From a report: They could boost energy density by an order of magnitude above conventional lithium-ion batteries -- in theory, at least. In a paper published this week in Science journal, researchers at the University of Waterloo identified ways of addressing some of the major hurdles to converting that potential into commercial reality.

A critical problem has been that as a lithium-oxygen battery discharges, oxygen is converted into superoxide and then lithium peroxide, reactive compounds that corrode the battery's components over time. That, in turn, limits its recharging ability -- and any real-world utility. To get around the problem, researchers switched from a carbon cathode to one made of nickel oxide and supported by a stainless steel mesh. They also used molten salt for the electrolyte -- the part of the battery that allows positively charged ions to move between the electrodes -- and raised the battery's operating temperature to 150C. Those steps made it possible to achieve about three times the number of charging cycles as earlier lithium-oxygen efforts. The researchers also managed to increase the energy per unit of mass by more than 50 percent.

The cybersecurity gig economy has expanded to hundreds of thousands of hackers, many of whom have had some experience in the IT security industry. Some still have jobs and hunt bugs in their spare time, while others make a living from freelancing. They are playing an essential role in helping to make code more secure at a time when attacks are rapidly increasing and the cost of maintaining dedicated internal security teams is skyrocketing. From a report: The best freelance bug spotters can make significant sums of money. HackerOne, which has over 200,000 registered users, says about 12 percent of the people using its service pocket $20,000 or more a year, and around 3 percent make over $100,000. The hackers using these platforms hail mostly from the US and Europe, but also from poorer countries where the money they can earn leads some to work full time on bug hunting.

Higher use of the world's dominant social network has now been strongly linked with more attacks on refugees in Germany. From a report: Greater use, greater violence: Specifically, in towns where "per-person Facebook use rose to one standard deviation above the national average," attacks on refugees "increased by about 50 percent," the New York Times reported today, citing a University of Warwick study. Researchers there carried out a detailed analysis of more than 3,000 incidents in Germany over a two-year period. Crucially, the link held true regardless of the city's size, political leanings, or economic status -- and didn't correlate with general patterns of internet use. Those findings strengthen the case that using Facebook in particular can be a driving mechanism of greater violence.

Greater scrutiny: That's more bad news for the embattled social network, which has long portrayed itself as a benevolent company driven by a mission to draw the world closer together. But researchers recently found that coordinated hate speech and propaganda on the site helped fuel violence in Myanmar. And last year, Facebook itself eventually acknowledged that Russian agents had posted tens of thousands of inflammatory posts -- which reached tens of millions of people -- before and after the 2016 presidential election, in a massive campaign to deepen divisions in the United States.

The sports world has been dealing with the human error of referees and umpires for decades -- it's pretty much tradition at this point. But with technology that can assess the game more accurately, some athletes are ready to push the people calling balls and strikes off the field in favor of technology. From a report: On Tuesday, Chicago Cubs second baseman Ben Zobrist, one of the most vocal supporters of turning over baseball rulings to software, used an argument with the umpire as a chance to advocate for a change in the league. The comment reinvigorated a long-standing debate over automation in sports. You're out! As you watch baseball on television, a graphic is often overlaid on the action that shows in real time whether a pitch is a ball or a strike. But human umps are still making the calls on the field based on nothing but their own eyes. Increasingly, viewers and players would rather have the technology take over.

Last August, 50 employees at Three Square Market got RFID chips in their hands. Now 80 have them. From a report: The idea came about in early 2017, president of Three Square Market Patrick McMullan says, when he was on a business trip to Sweden -- a country where some people are getting subcutaneous microchips to do things like enter secure buildings or book train tickets. It's one of very few places where chip implants, which have been around for quite a while, have taken off in some fashion. The chips he and his employees got are about the size of a very large grain of rice. They're intended to make it a little easier to do things like get into the office, log on to computers, and buy food and drinks in the company cafeteria. Like many RFID chips, they are passive -- they don't have batteries, and instead get their power from an RFID reader when it requests data from the chip.

A year into their experiment, McMullan and a few employees say they are still using the chips regularly at work for all the activities they started out with last summer. Since then, an additional 30 employees have gotten the chips, which means that roughly 80 of the company's now 250 employees, or nearly a third, are walking, talking cyborgs. "You get used to it; it's easy," McMullan says. As far as he knows, just two Three Square Market employees have had their chips removed -- and that was when they left the company.

Artificial intelligence will reshape the world of finance over the next decade or so by automating investing and other services -- but it could also introduce troubling systematic weaknesses and risks, according to a new report from the World Economic Forum (WEF). From a report: Compiled through interviews with dozens of leading financial experts and industry leaders, the report concludes that artificial intelligence will disrupt the industry by allowing early adopters to outmaneuver competitors. It also suggests that the technology will create more convenient products for consumers, such as sophisticated tools for managing personal finances and investments.

But most notably, the report points to the potential for big financial institutions to build machine-learning-based services that live in the cloud and are accessed by other institutions. "The dynamics of machine learning create a strong incentive to network the back office," says the report's main author, Jesse McWaters, who leads the AI in Financial Services Project at the World Economic Forum. "A more networked world is more vulnerable to cybersecurity risks, and it also creates concentration risks." Further reading: AI to Reshape Finance, Say Executives Who Struggle to Define It.

Students from Fast.ai, a small organization that runs free machine-learning courses online, just created an AI algorithm that outperforms code from Google's researchers, per an important benchmark. From a report: Fast.ai's success is important because it sometimes seems as if only those with huge resources can do advanced AI research. Fast.ai consists of part-time students keen to try their hand at machine learning -- and perhaps transition into a career in data science. It rents access to computers in Amazon's cloud. But Fast.ai's team built an algorithm that beats Google's code, as measured using a benchmark called DAWNBench, from researchers at Stanford. This benchmark uses a common image classification task to track the speed of a deep-learning algorithm per dollar of compute power. Google's researchers topped the previous rankings, in a category for training on several machines, using a custom-built collection its own chips designed specifically for machine learning. The Fast.ai team was able to produce something even faster, on roughly equivalent hardware.

Facing criticism from fellow scientists, the researcher behind the world's largest effort to edit human embryos with CRISPR is vowing to continue his efforts to develop what he calls "IVF gene therapy." MIT Technology Review: Shoukhrat Mitalipov, of Oregon Health Sciences University in Portland, drew global headlines last August when he reported successfully repairing a genetic mutation in dozens of human embryos, which were later destroyed as part of the experiment. The laboratory findings on early-stage embryos, he said, had brought the eventual birth of the first genetically modified humans "much closer" to reality. The breakthrough drew wide attention, including from critics who quickly pounced, calling it biologically implausible and potentially the result of careless errors and artifacts. Today, those critics are getting an unusual hearing in the journal Nature, which is publishing two critiques of the Oregon research as well as a lengthy reply from Mitalipov and 31 of his coworkers in South Korea, China, and the Salk Institute in La Jolla, California. The scientific sparring centers on CRISPR's well-known tendency to introduce unseen damage into a cell's DNA.

[...] Mitalipov remains intent on proving that CRISPR can work safely on embryos. In an interview, Mitalipov said he believes it will take five to 10 years before the process is ready to attempt in an IVF center. The revolutionary medical technology being pursued is a way to adjust an embryo's DNA to remove disease risks. It is sometimes called germline gene editing because any DNA fixes a baby is born with would then be passed down to future generations through that person's germ cells, the egg or sperm. For its initial research, the Oregon team recruited women around Portland and paid them $5,000 each to undergo an egg retrieval. With those eggs the team created more than 160 embryos for CRISPR experiments. Mitalipov said his Oregon center continues to obtain eggs in an ongoing effort to confirm his results and extend them in new directions.

This week's Black Hat event will highlight job-related stress and mental health issues in the cyber workforce. From a report: The thousands of cybersecurity professionals gathering at Black Hat, a massive conference held in the blistering heat of Las Vegas every summer, are encountering a different type of session this year. A new "community" track is offering talks on a range of workplace issues facing defenders battling to protect the world from a hacking onslaught. With titles like "Mental Health Hacks: Fighting Burnout, Depression and Suicide in the Hacker Community" and "Holding on for Tonight: Addiction in Infosec," several of the sessions will address pressures on security teams and the negative impact these can have on workers' wellbeing.

"A lot of people in this space feel strongly about wanting to protect their users," says Jamie Tomasello of Duo Security, who is one of the speakers. "Where this becomes challenging is when people are under sustained high stress. That increases the risk of depression and mental illness." The impact on cyber defenders' lives is deeply concerning, as are the broader implications for security. In spite of a push for greater automation, many tasks in cyber defense are still labor intensive. Workers experiencing mental health issues are more likely to make mistakes and to have performance issues that require colleagues to pick up the slack, increasing the likelihood they will make errors too.

Fake video clips made with artificial intelligence can also be spotted using AI -- but this may be the beginning of an arms race. From a report: The first forensics tools for catching revenge porn and fake news created with AI have been developed through a program run by the US Defense Department. Forensics experts have rushed to find ways of detecting videos synthesized and manipulated using machine learning because the technology makes it far easier to create convincing fake videos that could be used to sow disinformation or harass people. The most common technique for generating fake videos involves using machine learning to swap one person's face onto another's. The resulting videos, known as "deepfakes," are simple to make, and can be surprisingly realistic. Further tweaks, made by a skilled video editor, can make them seem even more real. Video trickery involves using a machine-learning technique known as generative modeling, which lets a computer learn from real data before producing fake examples that are statistically similar. A recent twist on this involves having two neural networks, known as generative adversarial networks, work together to produce ever more convincing fakes. The tools for catching deepfakes were developed through a program -- run by the US Defense Advanced Research Projects Agency (DARPA) -- called Media Forensics. The program was created to automate existing forensics tools, but has recently turned its attention to AI-made forgery.

The Defense Advanced Research Projects Agency (DARPA), which funds a range of blue-sky research efforts relevant to the US military, last year launched a $1.5 billion, five-year program known as the Electronics Resurgence Initiative (ERI) to support work on advances in chip technology. It has now unveiled the first set of research teams selected to explore unproven but potentially powerful approaches that could revolutionize US chip development and manufacturing. From a report: The ERI's budget represents around a fourfold increase in DARPA's typical annual spending on hardware. Initial projects reflect the initiative's three broad areas of focus: chip design, architecture, and materials and integration. One project aims to radically reduce the time it takes to create a new chip design, from years or months to just a day, by automating the process with machine learning and other tools so that even relatively inexperienced users can create high-quality designs.

"No one yet knows how to get a new chip design completed in 24 hours safely without human intervention," says Andrew Kahng of the University of California, San Diego, who's leading one of the teams involved. "This is a fundamentally new approach we're developing." William Chappell, the head of the DARPA office that manages the ERI program, said, "We're trying to engineer the craft brewing revolution in electronics." The agency hopes that the automated design tools will inspire smaller companies without the resources of giant chip makers, just as specialized brewers in the US have innovated alongside the beer industry's giants.

An anonymous reader quotes a report from MIT Technology Review: Is it possible to see the effects of the Fukushima nuclear disaster in California wines produced at the time? Today we get an answer, thanks to a study carried out by french pharmacologist Philippe Hubert and a couple of colleagues. "In January 2017, we came across a series of Californian wines (Cabernet Sauvignon) from vintage 2009 to 2012," say Hubert and company. This set of wines provides the perfect test. The Fukushima disaster occurred on March 11, 2011. Any wine made before that date should be free of the effects, while any dating from afterward could show them. The team began their study with the conventional measurement of cesium-137 levels in the unopened bottles. That showed levels to be indistinguishable from background noise.

But the team was able to carry out more-sensitive tests by opening the wine and reducing it to ash by evaporation. This involves heating the wine to 100 degrees Celsius for one hour and then increasing the temperature to 500 degrees Celsius for eight hours. In this way, a standard 750-milliliter bottle of wine produces around four grams of ashes. The ashes were then placed in a gamma ray detector to look for signs of cesium-137. Using this method, Hubert and his colleagues found measurable amounts of cesium-137 above background levels in the wine produced after 2011. "It seems there is an increase in activity in 2011 by a factor of two," conclude the team.

An anonymous reader shares a report: Of the 100 images submitted to the 2018 Robotart competition, an automaton called CloudPainter rose to the top, with evocative portraits featuring varying degrees of abstraction. One of its winning images was created by a team of neural networks, AI algorithms, and robots. Robotart's founder, Andrew Conru, told MIT Technology Review that this year's entries have shown refined brushstrokes and composition. "CloudPainter, the winner this year, has been involved all three years and has made the most improvement in his system," he says. "The resulting work, while it still uses an inputted photo as reference, can execute paintings using different painting styles."

Climate discussions typically center on the need to replace fossil-fuel power plants with technologies like wind turbines and solar panels. But a new paper in Science offers a stark reminder that there are still huge parts of the global energy system where we simply don't have affordable ways of halting greenhouse-gas emissions. MIT Technology Review: Air travel, long-distance transportation and shipping, steel and cement manufacturing, and remaining parts of the power sector account for 27 percent of global emissions from the energy and industrial sectors. And the authors say we need much more research, innovation, and strategic coordination to clean up these sources. "If we're really ambitious about meeting our climate targets, we need to be tackling these hard sectors now," says the paper's lead author, Steven Davis, an earth system scientist at the University of California, Irvine.

An anonymous reader shares a report: The US remains well behind pace to meet its commitments to cut greenhouse-gas emissions under the landmark Paris climate agreement. Under current policies, the nation will reduce climate pollution between 12 and 20 percent from 2005 levels by 2025, according to a Rhodium Group analysis published today. That's well below the 26 to 28 percent target agreed to under the Paris accords. The report estimates that total emissions between 2020 and 2030 could be 196 million metric tons lower than Rhodium projected last year. That's due to an increase in the number of planned coal plant closures, as well as the falling costs of natural gas, renewables, and electric vehicles. Slower economic growth forecasts were also a factor.

United Therapeutics, a startup that sells drugs to treat lung ailments, plans to use a 3-D printer to manufacture human lungs in "unlimited quantities." Bioprinting isn't a new idea. 3-D printers can make human skin, even retinas. Yet the method has been limited to tissues that are very small or very thin and lack blood vessels. From a report: United instead is developing a printer that it believes will be able, within a few years, to manufacture a solid, rubbery outline of a lung in exquisite detail, including all 23 descending branches of the airway, the gas-exchanging alveoli, and a delicate network of capillaries. A lung made from collagen won't help anyone: it's to a real lung what a rubber chicken is to an actual hen. So United is also developing ways to impregnate the matrix with human cells so they'll attach and burrow into it, bringing it alive.

[...] United has already made some risky organ bets. One of its subsidiaries, Revivicor, supplies surgeons with hearts, kidneys, and lungs from genetically engineered pigs (these have been used in baboons, so far). Another, Lung Bioengineering, refurbishes lungs from human donors by pumping warm solution into them. About 250 people have already received lungs that would otherwise have been designated medical waste. Don't expect fully manufactured organs soon. United, in its company projections, predicts it won't happen for another 12 years. United CEO Martine Rothblatt acknowledges that the printed structure I saw is just a start. "It's only two branches and no cells," she says.

An anonymous reader writes: Conamix, a little-known startup based in Ithaca, New York, has raised several million dollars to accelerate its development of cobalt-free materials for lithium-ion batteries, the latest sign that companies are eager to find alternatives to the increasingly rare and expensive metal. The problem: The price of cobalt has more than doubled in recent months, as global demand skyrockets for the lithium-ion batteries that power electric vehicles and smartphones. It's also being driven up by the fact that the metal is mined primarily in the Democratic Republic of Congo, where labor and corruption issues are rife. Earlier this year, the nation decided to raise royalties on cobalt and other metals.

Given the ambitious expansion plans of lithium-ion producers, the world will face cobalt shortages by the early 2020s, according to Bloomberg New Energy Finance. This is keeping prices of lithium-ion batteries high and preventing major automakers from lining up long-term supply deals on favorable terms. The mounting threat to electric-vehicle growth has prompted a growing number of companies to explore other solutions.

Lindsay, a compact rectangle amid the lakes northeast of Toronto, is at the heart of one of the world's biggest tests of a guaranteed basic income. Technology Review: In a three-year pilot funded by the provincial government, about 4,000 people in Ontario are getting monthly stipends to boost them to at least 75 percent of the poverty line. That translates to a minimum annual income of $17,000 in Canadian dollars (about $13,000 US) for single people, $24,000 for married couples. Lindsay has about half the people in the pilot -- some 10 percent of the town's population. The report outlines that the Canadian province's vision for a basic income -- and the underlying experiment -- differs from that of the one we have seen in Silicon Valley. The report continues: The Canadians are testing it as an efficient antipoverty mechanism, a way to give a relatively small segment of the population more flexibility to find work and to strengthen other strands of the safety net. That's not what Silicon Valley seems to imagine, which is a universal basic income that placates broad swaths of the population.

The most obvious problem with that idea? Math. Many economists concluded long ago that it would be too expensive, especially when compared with the cost of programs to create new jobs and train people for them. That's why the idea didn't take off after tests in the 1960s and '70s. It's largely why Finland recently abandoned a basic-income plan after a small test.

An anonymous reader quotes a report from MIT Technology Review: [Stephen McAleer and colleagues from the University of California, Irvine] have pioneered a new kind of deep-learning technique, called "autodidactic iteration," that can teach itself to solve a Rubik's Cube with no human assistance. The trick that McAleer and co have mastered is to find a way for the machine to create its own system of rewards. Here's how it works. Given an unsolved cube, the machine must decide whether a specific move is an improvement on the existing configuration. To do this, it must be able to evaluate the move. Autodidactic iteration does this by starting with the finished cube and working backwards to find a configuration that is similar to the proposed move. This process is not perfect, but deep learning helps the system figure out which moves are generally better than others. Having been trained, the network then uses a standard search tree to hunt for suggested moves for each configuration.

The result is an algorithm that performs remarkably well. "Our algorithm is able to solve 100% of randomly scrambled cubes while achieving a median solve length of 30 moves -- less than or equal to solvers that employ human domain knowledge," say McAleer and co. That's interesting because it has implications for a variety of other tasks that deep learning has struggled with, including puzzles like Sokoban, games like Montezuma's Revenge, and problems like prime number factorization. The paper on the algorithm -- called DeepCube -- is available on Arxiv.

An anonymous reader quotes a report from Reuters: Future Mobility Corporation (FMC), the Chinese parent company behind electric car start-up Byton, has placed an order for a paint shop capable of handling 150,000 cars per year, German supplier Duerr said on Wednesday. China's Byton, a newcomer headed by the former head of BMW's i8 program, has already released plans for a premium electric SUV vehicle, the latest in a series of China-backed electric autonomous prototypes. Byton has financial backing from Chinese state-owned carmaker FAW Group and the country's dominant battery producer Contemporary Amperex Technology Co. (CATL) This is just one of the stories this week relating to China and the electric car industry. MIT Technology Review adds: In a public offering on June 11 in Shenzhen, battery giant Contemporary Amperex Technology Ltd. (CATL) raised nearly $1 billion to fund ambitious expansion plans, and its stock has been shooting up every day since. Thanks largely to the company's new plants, China will be making 70 percent of the world's electric-vehicle batteries by 2021, according to Bloomberg New Energy Finance (BNEF).

Just seven years later, CATL has built up the biggest lithium-ion manufacturing facilities in the world, according to BNEF. The company can crank out around 17 gigawatt-hours of lithium-ion cells annually, placing it just ahead of Korea's LG Chem, the Tesla and Panasonic partnership, and China's electric-vehicle giant BYD. Flush with capital from its offering, CATL plans to build two new plants and expand existing facilities, pushing its capacity to nearly 90 gigawatt-hours by 2020. [...] Notably, it's the only Chinese battery company so far to line up deals to supply foreign automakers, including BMW, Honda, Nissan, Toyota, and Volkswagen.

An anonymous reader quotes a report from MIT Technology Review: While avoiding the worst dangers of climate change will likely require sucking carbon dioxide out of the sky, prominent scientists have long dismissed such technologies as far too expensive. But a detailed new analysis published today in the journal Joule finds that direct air capture may be practical after all. The study concludes it would cost between $94 and $232 per ton of captured carbon dioxide, if existing technologies were implemented on a commercial scale. One earlier estimate, published in Proceedings of the National Academies, put that figure at more than $1,000 (though the calculations were made on what's known as an avoided-cost basis, which would add about 10 percent to the new study's figures). Crucially, the lowest-cost design, optimized to produce and sell alternative fuels made from the captured carbon dioxide, could already be profitable with existing public policies in certain markets. The higher cost estimates are for plants that would deliver compressed carbon dioxide for permanent underground storage. David Keith, a Harvard physics professor and lead author of the paper, is also the founder of Carbon Engineering, "a Calgary-based startup that has spent the last nine years designing, refining, and testing a direct air capture pilot plant in Squamish, B.C.," reports MIT. "Carbon Engineering plans to combine the carbon captured at its plants with hydrogen to produce carbon-neutral synthetic fuels, a process the pilot facility has already been performing." The company has secured $30 million, but is seeking additional funds to build a larger facility that will begin selling fuels. CNBC notes that Carbon Engineering is owned by several private investors, including Bill Gates.

Speaking at a conference held at MIT, Donald Trump's chief technology advisor, Michael Kratsios, said this week that the U.S. government would release any data that might help fuel AI research in the United States, although he didn't specify immediately what kind of data would be released or who would be eligible to receive the information. From a report: Kratsios, who is deputy assistant to the president and deputy US chief technology officer, said the government is looking for ways to open up federal data to AI researchers. "Anything that we can do to unlock government data, we're committed to," Kratsios told MIT Technology Review. "We'd love to hear from any academic that has any insights." Data has been a key factor behind recent advances in artificial intelligence. For example, better voice recognition and image processing have been contingent on the availability of huge quantities of training data. The government has access to large amounts of data, and it's possible that it could be used to train innovative algorithms to do new things. "Anything we can do to figure that out, we will work very hard on," Kratsios added.

The Trump administration has faced criticism for a more laissez-faire approach to artificial intelligence than many other countries have taken. Kratsios argued that the White House is quietly pushing an aggressive policy, pointing to examples of research projects that have received federal funding. When asked about the president's interest in artificial intelligence, Kratsios said, "The White House has prioritized AI, and he obviously runs the White House."

Amazon's fleet of automated warehouse robots, now more than 100,000 machines strong, is working alongside human employees to help meet the e-commerce giant's massive fulfillment demand. From a report: The company's robots carry inventory around massive warehouse floors, compiling all the items for a customer's order and reducing the need for human interaction with the products. But the chief technologist of Amazon Robotics, Tye Brady, insists that these robots are enhancing human efficiencies rather than eliminating warehouse jobs.

Amazon has been going full steam ahead when it comes to hiring and now employs over 500,000 people. Brady views the robots as necessary to this growth. "When there are tens of thousands of orders going on simultaneously, you are getting beyond what a human can do," he told the audience at MIT Technology Review's first EmTech Next conference today. Humans still provide necessary skills in the fulfillment process, like dexterity, adaptiveness, and plain old common sense. For example, when some popcorn butter accidentally fell off a pod in a fulfillment center, it got squished, creating a big buttery mess in the middle of the floor. The curious robots didn't know how to handle the situation but wanted to go check it out. "The robots were driving through it, and they'd slip and get an encoder error," says Brady.

A trial planning to use the gene-editing tool CRISPR on sickle cell patients has been put on hold due to unspecified questions from US regulators. From a report: CRISPR Therapeutics, which is developing the therapy, sought approval from the US Food and Drug Administration in April to begin the study. The therapy involves extracting stem cells from a patient's bone marrow and editing them with CRISPR in the lab. Once infused back into the patient, the idea is that the edited cells would give rise to healthy red blood cells. But according to a statement on Wednesday from CRISPR Therapeutics, the FDA ordered the company not to proceed with its study until it answers questions about its CRISPR treatment.

Thousands of unionized hotel and casino workers in Las Vegas are ready to go on strike for the first time in more than three decades. From a report: Members of the Culinary Union, who work in many of the city's biggest casinos, have voted to approve a strike unless a deal is reached soon. Some background: On June 1, the contracts of 50,000 union workers expire, making them eligible to strike. Employees range from bartenders to guest room attendants. The last casino worker strike, in 1984, lasted 67 days and cost more than $1 million a day. Why? Higher wages, naturally. But the workers are also looking for better job security, especially from robots. "We support innovations that improve jobs, but we oppose automation when it only destroys jobs," says Geoconda Arguello-Kline, secretary-treasurer for the Culinary Union. "Our industry must innovate without losing the human touch."

An anonymous reader shares a report: There are trillions of reasons for the world to prevent temperatures from rising more than 1.5C, the aspirational target laid out in the Paris climate agreement, according to a new study. If nations took the necessary actions to meet that goal, rather than the increasingly discussed 2C objective, there's a 60 percent chance it would save the world more than $20 trillion, according to new work published this week in Nature by scientists at Stanford. That figure is far higher than what most experts think it will cost to cut emissions enough to achieve the 1.5C target. Indeed, one study put the price tag in the hundreds of billions of dollars. If temperatures rise by 3C, it will knock out an additional 5 percent of GDP. That's the entire planet's GDP.

The Department of Defense is funding a project that will try to determine whether the increasingly real-looking fake video and audio generated by artificial intelligence might soon be impossible to distinguish from the real thing -- even for another AI system. From a report: This summer, under a project funded by the Defense Advanced Research Projects Agency (DARPA), the world's leading digital forensics experts will gather for an AI fakery contest. They will compete to generate the most convincing AI-generated fake video, imagery, and audio -- and they will also try to develop tools that can catch these counterfeits automatically. The contest will include so-called "deepfakes," videos in which one person's face is stitched onto another person's body.

Rather predictably, the technology has already been used to generate a number of counterfeit celebrity porn videos. But the method could also be used to create a clip of a politician saying or doing something outrageous. DARPA's technologists are especially concerned about a relatively new AI technique that could make AI fakery almost impossible to spot automatically. Using what are known as generative adversarial networks, or GANs, it is possible to generate stunningly realistic artificial imagery.

The White House has set up a new task force dedicated to US artificial intelligence efforts, the Trump administration announced today during an event with technology executives, government leaders, and AI experts. From a report: The news and the event, which was organized by the federal government, are both moves to further the country's AI development, as other regions like Europe and Asia ramp up AI investment and R&D as well. The administration will be further investing in AI, deputy CTO of the White House's Office of Science and Technology Policy Michael Kratsios said at the event.

"To realize the full potential of AI for the American people, it will require the combined efforts of industry, academia, and government," Kratsios said, according to FedScoop. According to the Trump administration, the federal government has increased its investment in unclassified R&D for AI by 40 percent since 2015. In his speech, Kratsios highlighted ways the US could improve AI advancement, such as robotics startups in Pittsburgh that are models for how to spur job growth in areas hurt by workplace automation. Startups like those now hire engineers, scientists, bookkeepers, and administrators, he said, and are evidence that AI does not necessarily mean massive unemployment is on the horizon. Further reading: The White House says a new AI task force will protect workers and keep America first (MIT Tech Review).

The idea is simple, if you ask biologist George Church. He wants to live to 130 in the body of a 22-year-old. From a report: The world's most influential synthetic biologist is behind a new company that plans to rejuvenate dogs using gene therapy. If it works, he plans to try the same approach in people, and he might be one of the first volunteers. The stealth startup Rejuvenate Bio, cofounded by George Church of Harvard Medical School, thinks dogs aren't just man's best friend but also the best way to bring age-defeating treatments to market. The company, which has carried out preliminary tests on beagles, claims it will make animals "younger" by adding new DNA instructions to their bodies.

Its age-reversal plans build on tantalizing clues seen in simple organisms like worms and flies. Tweaking their genes can increase their life spans by double or better. Other research has shown that giving old mice blood transfusions from young ones can restore some biomarkers to youthful levels. "We have already done a bunch of trials in mice and we are doing some in dogs, and then we'll move on to humans," Church told the podcaster Rob Reid earlier this year. The company's efforts to keep its activities out of the press make it unclear how many dogs it has treated so far. In a document provided by a West Coast veterinarian, dated last June, Rejuvenate said its gene therapy had been tested on four beagles with Tufts Veterinary School in Boston. It is unclear whether wider tests are under way.

However, from public documents, a patent application filed by Harvard, interviews with investors and dog breeders, and public comments made by the founders, MIT Technology Review assembled a portrait of a life-extension startup pursuing a longevity long shot through the $72-billion-a-year US pet industry. "Dogs are a market in and of themselves," Church said during an event in Boston last week. "It's not just a big organism close to humans. It's something people will pay for, and the FDA process is much faster. We'll do dog trials, and that'll be a product, and that'll pay for scaling up in human trials."

Long-time Slashdot reader Okian Warrior quotes Live Science: The CEO of a biomedical startup who sparked controversy when he injected himself with an untested herpes treatment in front of a live audience in February has died, according to an email sent to Live Science. Aaron Traywick, the CEO of Ascendance Biomedical, was found dead at 11:30 a.m. ET on Sunday (April 29) in a spa room in Washington, D.C., according to a statement provided to Live Science by the Metropolitan Police Department (MPD) of the District of Columbia. Traywick was 28 years old. According to the website News2Share.com, Traywick was found in a flotation tank. Flotation tanks are soundproof pods filled with body-temperature saltwater that are used to promote "sensory deprivation."
Vice News reports that Traywick had "lost touch" with co-workers at his company more than four weeks ago, adding that "Disagreements over the company's direction and philosophical differences over how to best distribute its creations split the small startup."

MIT Technology Review reports that Traywick, "who had no formal medical training, was also planning to test an experimental lung cancer treatment that supposedly involved the gene-editing tool CRISPR.
