Researchers Have Teamed Up in India To Build a Gigantic Store of Texts and Images Extracted From 73M Journal Articles (nature.com) 32

A giant data store quietly being built in India could free vast swathes of science for computer analysis -- but whether it is a legal pursuit remains unclear. From a report: Carl Malamud is on a crusade to liberate information locked up behind paywalls -- and his campaigns have scored many victories. He has spent decades publishing copyrighted legal documents, from building codes to court records, and then arguing that such texts represent public-domain law that ought to be available to any citizen online. Sometimes, he has won those arguments in court. Now, the 60-year-old American technologist is turning his sights on a new objective: freeing paywalled scientific literature. And he thinks he has a legal way to do it. Over the past year, Malamud has -- without asking publishers -- teamed up with Indian researchers to build a gigantic store of text and images extracted from 73 million journal articles dating from 1847 up to the present day.

The cache, which is still being created, will be kept on a 576-terabyte storage facility at Jawaharlal Nehru University (JNU) in New Delhi. "This is not every journal article ever written, but it's a lot," Malamud says. It's comparable to the size of the core collection in the Web of Science database, for instance. Malamud and his JNU collaborator, bioinformatician Andrew Lynn, call their facility the JNU data depot. No one will be allowed to read or download work from the repository, because that would breach publishers' copyright. Instead, Malamud envisages, researchers could crawl over its text and data with computer software, scanning through the world's scientific literature to pull out insights without actually reading the text. The unprecedented project is generating much excitement because it could, for the first time, open up vast swathes of the paywalled literature for easy computerized analysis.

Dozens of research groups already mine papers to build databases of genes and chemicals, map associations between proteins and diseases, and generate useful scientific hypotheses. But publishers control -- and often limit -- the speed and scope of such projects, which typically confine themselves to abstracts, not full text. Researchers in India, the United States and the United Kingdom are already making plans to use the JNU store instead. Malamud and Lynn have held workshops at Indian government laboratories and universities to explain the idea. "We bring in professors and explain what we are doing. They get all excited and they say, 'Oh gosh, this is wonderful'," says Malamud. But the depot's legal status isn't yet clear. Malamud, who contacted several intellectual-property (IP) lawyers before starting work on the depot, hopes to avoid a lawsuit.

Chinese Space Station Tiangong-2 Is About To Fall From Space (newscientist.com) 149

The Chinese space station Tiangong-2 is scheduled to drop out of orbit on July 19 and fall into the Pacific Ocean between New Zealand and Chile. New Scientist reports: Tiangong-2 -- which translates as "heavenly palace" -- was launched in September 2016, and it was never intended to be a permanent fixture in orbit. Instead, its purpose was to test technologies for China's larger planned space station, whose main module is scheduled to launch in 2020. That space station is planned to be about one-fifth the size of the International Space Station. Tiangong-2 is far smaller. In 2018, Tiangong-2 began to lower its orbit to prepare for the end of its mission. On 19 July, it will fire its thrusters again to aim its descent toward the Pacific Ocean. Most of the craft will probably burn up as it enters the atmosphere, but any parts that survive should splash into the water harmlessly. Its predecessor, Tiangong-1, lost power in April 2018 and crashed in an uncontrolled fashion.

Google Glass May Have an Afterlife As a Device To Teach Autistic Children (nytimes.com) 56

While Google stopped selling its augmented-reality glasses to customers due to privacy concerns, Google Glass lived on as something to be used by researchers and businesses. The New York Times reports of a new effort from Stanford researchers to use Google Glass to help autistic children understand emotions and engage in more direct ways with those around them. The glasses could also be used to measure changes in behavior, something that has historically been difficult to do. An anonymous Slashdot reader shares an excerpt from the report: When Esaie Prickett sat down in the living room with his mother, father and four older brothers, he was the only one wearing Google Glass. As Esaie, who was 10 at the time and is 12 now, gazed through the computerized glasses, his family made faces -- happy, sad, surprised, angry, bored -- and he tried to identify each emotion. In an instant, the glasses told him whether he was right or wrong, flashing tiny digital icons that only he could see.

Esaie was 6 when he and his family learned he had autism. The technology he was using while sitting in the living room was meant to help him learn how to recognize emotions and make eye contact with those around him. The glasses would verify his choices only if he looked directly at a face. He and his family tested the technology for several weeks as part of a clinical trial run by researchers at Stanford University in and around the San Francisco Bay Area. Recently detailed in The Journal of the American Medical Association, Pediatrics, the trial fits into a growing effort to build new technologies for children on the autism spectrum, including interactive robots and computerized eyewear.

Jeff Bezos: I Spend My Billions On Space Because We're Destroying Earth (cnbc.com) 330

In an interview with Norah O'Donnell of "CBS Evening News," Amazon CEO Jeff Bezos explained why he's investing much of his Amazon fortune in the development of space technologies through his aerospace company Blue Origin. Why? "Because I think it's important," Bezos said. "I think it is important for this planet. I think it's important for the dynamism of future generations. It is something I care deeply about. And it is something I have been thinking about all my life." From the report: Bezos -- who says "you don't choose your passions, your passions choose you" -- became fascinated with space when he was a child watching astronauts Buzz Aldrin and Neil Armstrong land on the moon, he tells O'Donnell. Further, developing space technologies is critical for human beings to have a long future, Bezos says. "We humans have to go to space if we are going to continue to have a thriving civilization," Bezos says. "We have become big as a population, as a species, and this planet is relatively small. We see it in things like climate change and pollution and heavy industry. We are in the process of destroying this planet. And we have sent robotic probes to every planet in the solar system -- this is the good one. So, we have to preserve this planet."

To do that will require being able to live and work in space, says Bezos. "We send things up into space, but they are all made on Earth. Eventually it will be much cheaper and simpler to make really complicated things, like microprocessors and everything, in space and then send those highly complex manufactured objects back down to earth, so that we don't have the big factories and pollution generating industries that make those things now on Earth," Bezos says. "And Earth can be zoned residential." It will be "multiple generations" and "hundreds of years" before this is a reality, Bezos said on CBS, but with Blue Origin he is working to develop the technology that will make it possible.

Delta, Alaska, and American Airlines Have All Been Sued Over Their Uniforms. (vox.com) 99

Rashes, blisters, and hair loss have all been reported. So has vomiting, migraines, and shortness of breath. All of these -- and more -- are symptoms reported by flight attendants after their airlines got new uniforms. But no one knows why. From a report: Delta is the latest airline to have flight attendants report health issues possibly related to their uniforms, and employees at the airline filed a lawsuit in May against the manufacturer, Lands' End. But flight attendants have been battling health issues that have appeared after an airline instituted new uniforms for years. And for years, airlines have said their uniforms are safe. Meanwhile, flight attendants and others are working to discover the cause of their symptoms and the identity and total number of chemicals present in their uniforms, all of which can be difficult to ascertain. Until the cause can be identified -- or until airlines start listening to employees and moving quickly after their complaints -- it's likely employees will continue to face symptoms. And it's likely that flight attendants will keep heading to court, where they've historically needed to go to get policy changed by their employers.

The problem was first reported after employees at Alaska Airlines got new uniforms toward the end of 2010 and beginning of 2011. Flight attendants began to report rashes and eye irritation, and documented hives, blisters, and scaly patches, according to a 2012 National Institute for Occupational Safety and Health (NIOSH) report looking into the issue. In 2013, flight attendants at Alaska Airlines filed a lawsuit against the manufacturer of the uniforms, Twin Hill, and the airline recalled the uniforms in 2014. In October 2016, Twin Hill won the lawsuit, with the court claiming there was no reliable evidence the injuries were caused by the uniforms.

Apollo 11 Had a Hidden Hero: Software (wsj.com) 171

"Monday's Wall Street Journal includes a special Apollo 11 feature," writes Slashdot reader Outatime in honor of the 50th anniversary since Apollo 11's Saturn V launched from the Kennedy Space Center. "[O]f particular interest to many Slashdot nerds is the piece on the pioneering computer hardware and software that took three astronauts, and landed two, on the moon." Here's an excerpt from the report: The [MIT Instrumentation Laboratory or I-Lab] was housed in a former underwear factory overlooking the Charles River, now long since demolished. The Apollo engineers and programmers labored at scuffed metal desks in cubicles with code scribbled on the chalkboard, slide rules on the table, cigarette butts on the linoleum floor. Fanfold computer printouts were stacked up to 6 feet high, like termite mounds. The lab had pioneered inertial guidance systems for the nuclear-warhead-tipped missiles of the Cold War, such as the submarine-launched Polaris intercontinental ballistic missiles. Funded by the U.S. Air Force, it also developed a plan in the late 1950s to fly a computerized probe to Mars and back. MIT received the first major Apollo contract, the only one awarded to a university, and the only one given without competitive bidding.

In an era when a computer used fragile tubes, ran on punch cards and filled an entire room, the I-Lab engineers had invented a briefcase-size digital brain packed with cutting-edge integrated circuits and memory so robust it could withstand a lightning bolt -- a direct ancestor of almost all computers today. Unlike other machines of its era, it could juggle many tasks at once and make choices of which to prioritize as events unfolded. Apollo missions carried two of these computers, one aboard the command module and one in the lunar lander, running almost identical software. Only the lunar lander, though, required the extra code to set down safely on the moon.

Elon Musk Unveils Neuralink's Plans For Brain-Reading 'Threads' and a Robot To Insert Them (theverge.com) 201

Neuralink, the secretive company developing brain-machine interfaces, held a press conference today where it unveiled some of the technology it's been developing to the public for the first time. The first big advance is flexible "threads," which are less likely to damage the brain than the materials currently used in brain-machine interfaces and create the possibility of transferring a higher volume of data.

"The threads are 4 to 6 micrometers in width, which makes them considerably thinner than a human hair," reports The Verge. The other big advance that Neuralink unveiled is a machine that automatically embeds the threads into the brain. From the report: In the future, scientists from Neuralink hope to use a laser beam to get through the skull, rather than drilling holes, they said in interviews with The New York Times. Early experiments will be done with neuroscientists at Stanford University, according to that report. The company aims for human trials as soon as the second quarter of next year, according to The New York Times. The system presented today, if it's functional, may be a substantial advance over older technology. BrainGate relied on the Utah Array, a series of stiff needles that allows for up to 128 electrode channels. Not only is that fewer channels than Neuralink is promising -- meaning less data from the brain is being picked up -- it's also stiffer than Neuralink's threads. That's a problem for long-term functionality: the brain shifts in the skull but the needles of the array don't, leading to damage. The thin polymers Neuralink is using may solve that problem.

However, Neuralink's technology is more difficult to implant than the Utah Array, precisely because it's so flexible. To combat that problem, the company has developed "a neurosurgical robot capable of inserting six threads (192 electrodes) per minute [automatically]," according to the white paper. In photos, it looks something like a cross between a microscope and a sewing machine. It also avoids blood vessels, which may lead to less of an inflammatory response in the brain, the paper says. Finally, the paper says that Neuralink has developed a custom chip that is better able to read, clean up, and amplify signals from the brain. Right now, it can only transmit data via a wired connection (it uses USB-C), but ultimately the goal is to create a system than can work wirelessly.
Currently, the company is testing the robot and threads on rats, but it's hoping to actually begin working with human test subjects as early as next year.

US Heat Waves To Skyrocket As Globe Warms, Study Suggests (usatoday.com) 395

An anonymous reader quotes a report from USA Today: As the globe warms in the years ahead, days with extreme heat are forecasted to skyrocket across hundreds of U.S. cities, a new study suggests, perhaps even breaking the "heat index." By 2050, hundreds of U.S. cities could see an entire month each year with heat index temperatures above 100 degrees if nothing is done to rein in global warming. The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. This is the first study to take the heat index -- instead of just temperature -- into account when determining the impacts of global warming. The number of days per year when the heat index exceeds 100 degrees will more than double nationally, according to the study, which was published Tuesday in the journal Environmental Research Communications. On some days, conditions would be so extreme that they'd exceed the upper limit of the heat index, rendering it "incalculable," the study predicts. What is there to be done about this? "Rapidly reduce global warming emissions and help communities prepare for the extreme heat that is already inevitable," report co-author Astrid Caldas said. "Extreme heat is one of the climate change impacts most responsive to emissions reductions, making it possible to limit how extreme our hotter future becomes for today's children."

Scientists Close In On Blood Test For Alzheimer's (cbsnews.com) 50

pgmrdlm shares a report from CBS News: Scientists are closing in on a long-sought goal -- a blood test to screen people for possible signs of Alzheimer's disease and other forms of dementia. On Monday at the Alzheimer's Association International Conference, half a dozen research groups gave new results on various experimental tests, including one that seems 88% accurate at indicating Alzheimer's risk. Doctors are hoping for something to use during routine exams, where most dementia symptoms are evaluated, to gauge who needs more extensive testing. Current tools such as brain scans and spinal fluid tests are too expensive or impractical for regular check-ups. Dr. Richard Hodes, director of the National Institute on Aging, called the new results "very promising" and said blood tests soon will be used to choose and monitor people for federally funded studies, though it will take a little longer to establish their value in routine medical care. "In the past year we've seen a dramatic acceleration in progress" on these tests, he said. "This has happened at a pace that is far faster than any of us would have expected."

Cause of SpaceX Crew Dragon Explosion Revealed (cbsnews.com) 81

On April 20, a SpaceX Crew Dragon capsule, designed to take humans to the ISS, exploded during a routine test fire at Cape Canaveral Air Force Station. The cause has now been identified as a leaky valve in a propellant pressurization system. Thelasko shares a report from CBS News: Hans Koenigsmann, SpaceX vice president of build and reliability said: "We believe that we had a liquid slug of the (NTO) in the pressurization system. When we opened the valves and pressurized the propellant system, we think that this slug was driven back into the check valve. That basically destroyed the check valve and caused an explosion."

He said no one expected that "NTO driven into a titanium component would cause such a violent reaction. We then performed tests ... with the help of NASA, and we found out when the pressure is high, the temperature is high and you drive a slug with a lot of energy into a titanium component that you can have these rather violent reactions." Additional work is needed to rule out other less likely culprits but SpaceX is pressing ahead with plans to replace the valves in question with pressure-activated "burst discs" that have no moving parts and cannot leak.

Machine Learning Has Been Used To Automatically Translate Long-Lost Languages (technologyreview.com) 111

Jiaming Luo and Regina Barzilay from MIT and Yuan Cao from Google's AI lab in Mountain View, California, have developed a machine-learning system capable of deciphering lost languages, and they've demonstrated it on a script from the Mediterranean island of Crete. The script, Linear B, appeared after 1400 BCE, when the island was conquered by Mycenaeans from the Greek mainland. MIT Technology Review reports: Luo and co put the technique to the test with two lost languages, Linear B and Ugaritic. Linguists know that Linear B encodes an early version of ancient Greek and that Ugaritic, which was discovered in 1929, is an early form of Hebrew. Given that information and the constraints imposed by linguistic evolution, Luo and co's machine is able to translate both languages with remarkable accuracy. "We were able to correctly translate 67.3% of Linear B cognates into their Greek equivalents in the decipherment scenario," they say. "To the best of our knowledge, our experiment is the first attempt of deciphering Linear B automatically."

That's impressive work that takes machine translation to a new level. But it also raises the interesting question of other lost languages -- particularly those that have never been deciphered, such as Linear A. In this paper, Linear A is conspicuous by its absence. Luo and co do not even mention it, but it must loom large in their thinking, as it does for all linguists. Yet significant breakthroughs are still needed before this script becomes amenable to machine translation. For example, nobody knows what language Linear A encodes. Attempts to decipher it into ancient Greek have all failed. And without the progenitor language, the new technique does not work.

Scientists Could Use Aerogel Sheets To Make Mars Surface Fit For Farming (theguardian.com) 176

Scientists believe aerogel sheets could transform the cold, arid surface of Mars into land fit for farming. The Guardian reports: The "aerogel" sheets work by mimicking Earth's greenhouse effect, where energy from the sun is trapped on the planet by carbon dioxide and other gases. Spread out in the right places on Mars, the sheets would warm the ground and melt enough subsurface ice to keep plants alive. Should humans ever decide to spread beyond Earth, as the late Stephen Hawking declared we must, then growing food on alien worlds will be a skill that has to be mastered. But on Mars the conditions are hardly conducive. The planet is frigid and dry and bombarded by radiation, the soil contains potentially toxic chemicals and the wispy atmosphere is low on nitrogen.

The aerogel sheets do not solve all of the problems but they could help future spacefarers create fertile oases on desolate planets where plants and other photosynthesizing organisms can take root. Because life would only grow beneath the sheets, the risk of contaminating the rest of Mars with foreign lifeforms would be minimal. The aerogel used to make the sheets is composed 97% of air, with the rest made up of a light silica network. The researchers, including scientists at Nasa and the University of Edinburgh, showed that 2cm- to 3cm-thick sheets of silica aerogel blocked harmful UV rays, allowed visible light through for photosynthesis and trapped enough heat to melt frozen water locked in Martian soil. The sheets could be laid directly on the ground to grow algae and aquatic plants, or suspended to provide room for land plants to grow beneath them.
The researchers published their findings in the journal Nature Astronomy.

Elon Musk's Neuralink Will Detail Progress in Computer-Brain Interface (cnet.com) 75

Neuralink, Elon Musk's fourth and least visible company, will become a bit less secretive Tuesday with a livestreamed presentation about its technology to connect computers directly to human brains. From a report: Neuralink accepted applications from some folks to attend the San Francisco event to hear "a bit about what we've been working on the last two years," but the rest of us can tune in online at 8 p.m. PT Tuesday. "Livestream details will be available on our website shortly before event start," Neuralink tweeted Sunday. Neuralink, founded in 2016, is working on a way to let human brains communicate directly with computers. Goals include fast transfer rates and quick responses, but just establishing a connection and figuring out how to exchange useful information presents immense challenges. One possible approach involves an array of flexible probes inserted into the brain with a system resembling a sewing machine, an idea described by researchers reportedly associated with Neuralink. That's a lot cruder than the organically grown nanotechnological neural laces you'll find inside the brains of sci-fi characters, but it's remarkable that the technology is even under discussion.

Intel's Pohoiki Beach is a Neuromorphic Computer Capable of Simulating 8 Million Neurons (venturebeat.com) 58

During the Defense Advanced Research Projects Agency's (DARPA) Electronics Resurgence Initiative 2019 summit in Detroit, Michigan, Intel unveiled a system codenamed "Pohoiki Beach," a 64-chip computer capable of simulating 8 million neurons in total. From a report: Intel Labs managing director Rich Uhlig said Pohoiki Beach will be made available to 60 research partners to "advance the field" and scale up AI algorithms like spare coding and path planning. [...] Pohoiki Beach packs 64 128-core, 14-nanometer Loihi neuromorphic chips, which were first detailed in October 2017 at the 2018 Neuro Inspired Computational Elements (NICE) workshop in Oregon.

They have a 60-millimeter die size and contain over 2 billion transistors, 130,000 artificial neurons, and 130 million synapses, in addition to three managing Lakemont cores for task orchestration. Uniquely, Loihi features a programmable microcode learning engine for on-chip training of asynchronous spiking neural networks (SNNs) -- AI models that incorporate time into their operating model, such that components of the model don't process input data simultaneously. This will be used for the implementation of adaptive self-modifying, event-driven, and fine-grained parallel computations with high efficiency.

A Cell Tower In the Swiss Alps Is Struck By Lightning More Than 100 Times a Year (ieee.org) 90

Wave723 quotes IEEE Spectrum: Atop a rocky peak in the Swiss Alps sits a telecommunications tower that gets struck by lightning more than 100 times a year, making it perhaps the world's most frequently struck object. Taking note of the remarkable consistency with which lightning hits this 124-meter structure, researchers have adorned it with instruments for a front-row view of these violent electric discharges...

To anyone who has witnessed a lightning strike, everything seems to happen all at once. But [New Mexico Tech's Mark] Stanley's sensor captures several gigabytes of data about the many separate pulses that occur within each flash. Those data can be made into a video that replays, microsecond by microsecond, how "channels" of lightning form in the clouds.... [T]hey intend to use data gathered by the tower's many instruments (which include a collection of six antennas called a lightning mapping array, two Rogowski coils to measure current, two B-Dot sensors to measure the current time-derivative, broadband electric and magnetic field sensors, and a high-speed camera) to reconstruct the total path of strikes soon after they happen, tracing the electromagnetic radiation all the way back to its original source...

The Santis team's work has held particular relevance for wind farm operators. That's because most strikes recorded at the tower are examples of upward lightning -- which travels from ground-to-cloud instead of cloud-to-ground.

They hope to eventually help make progress on predicting where lightning will strike.

And by the end of this year, the team at the tower expect to record their 1,000th lightning strike.

NASA Funds Company To 3D-Print Spacecraft Parts in Orbit (engadget.com) 28

An anonymous reader quotes Engadget: NASA is expanding its efforts to bring 3D printing to space. The agency has given Made In Space a $73.3 million contract to demonstrate the ability to 3D-print spacecraft parts in orbit using Archinaut One, a robotic manufacturing ship due to launch in 2022 or later. The vessel will fly aboard a Rocket Lab Electron rocket and 3D-print two 32-foot beams on each side, with each unfurling two solar arrays. The completed arrays could produce up to five times more power than the solar panels you normally find on spacecraft this size, NASA said...

If successful, it could alter how NASA and others approach building and fixing spacecraft. This could lead to building spacecraft (albeit smaller ones at this stage) in orbit, of course, but it could also let space agencies launch small satellites that receive large power collectors once they're floating above Earth. It could also lead to fewer spacewalks by having robots build items that would otherwise require human involvement.

India Plans Historic Launch of a Rocket to the Moon (techcrunch.com) 89

The Indian Space Research Organization (ISRO) is planning to launch a rocket to the moon. UPDATE: 2:28: The launch "has been called off for today," the ISRO posted on Twitter.

But when the re-scheduled launch happens, you can watch it live on two YouTube channels, on Twitter, Facebook, or webcast on the ISRO's web site.

TechCrunch has also embedded a livestreaming video in their report: Chandrayaan-2 will carry lunar lander Vikram, which will deliver ISRO rover Pragyan to the surface at the pole, with a target landing zone of a plain that covers the ground between two of the Moon's craters, Simpelius N and Manzinus C. The rocket used for the launch is the GSLV Mk-III, India's most powerful launch vehicle ever, and the orbiter used for this mission will relay back information from the lander and rover to Earth via the Indian Deep Space Network, as well as make its own observations during its planned one-year mission lifespan.

The mission will seek to take a number of measurements of the lunar surface, including topographic, mineral makeup, seismographic, chemical analytics and more, with an eye to shedding more light on the Moon's origins. If all goes to plan, the lunar orbiter will make its way to to Moon over the next couple of months and aim to soft land the Vikram at the South Pole target site on September 6, 2019.

This is a historic mission for a few reasons, including being the first ever soft-landing attempt at the Moon's South Pole region, as well as being the first Indian mission to attempt a soft landing using all home-grown lander and rover technology. If successful, India will be only the fourth country ever to have soft-landed a vehicle on the lunar surface.

Doing Five Things Could Decrease Your Risk of Alzheimer's By 60% (sfgate.com) 132

"Light-to-moderate" alcohol consumption can help reduce your risk of Alzheimer's disease.

An anonymous reader quotes the Washington Post: A study presented Sunday at the Alzheimer's Association International Conference in Los Angeles found that combining five lifestyle habits -- including eating healthier, exercising regularly and refraining from smoking -- can reduce the risk of Alzheimer's by 60 percent. A separate study showed that lifestyle choices can lower risk even for those who are genetically prelifestyle disposed to the disease...

Over the last decade, studies have increasingly pointed to controllable lifestyle factors as critical compenents to reducing the risk of cognitive decline. Researchers say that, as with heart disease, combating dementia will probably require a "cocktail" approach combining drugs and lifestyle changes. And as recent efforts to develop a cure or more effective drug treatments for dementia have proven disappointing, the fact that people can exert some control in preventing the disease through their own choices is encouraging news, they say.

While the new study's authors expected to see that leading a healther life decreases the chance of dementia, they were floored by the "magnitude of the effect," said Klodian Dhana, a Rush University professor and co-author. "This demonstrates the potential of lifestyle behaviors to reduce risk as we age," said Heather Snyder, senior director of medical and scientific operations at the Alzheimer's Association. "The fact that four or five lifestyle habits put together can have that kind of benefit for your brain is incredibly powerful."

The fifth lifestyle habit is "engaging in mentally stimulating activities like reading the newspaper, visiting the library or playing games such as chess and checkers."

Time reports that even following just two or three of the healthy lifestyle factors reduced the risk of developing Alzheimer's dementia in the study by at least 39%.

IQ Test Scores Increased For a Century. But Did it Help? (bbc.com) 260

IQ test scores have been increasing for 100 years, reports a senior journalist at BBC Future. He also writes that there's evidence "that we may have already reached the end of this era -- with the rise in IQs stalling and even reversing."

But this raises an even larger question: did a century of increasing scores on IQ tests bring benefits to society? You might assume that the more intelligent you are, the more rational you are, but it's not quite this simple... Consider the abundant literature on our cognitive biases. Something that is presented as "95% fat-free" sounds healthier than "5% fat", for instance -- a phenomenon known as the framing bias. It is now clear that a high IQ does little to help you avoid this kind of flaw, meaning that even the smartest people can be swayed by misleading messages. People with high IQs are also just as susceptible to the confirmation bias -- our tendency to only consider the information that supports our pre-existing opinions, while ignoring facts that might contradict our views. That's a serious issue when we start talking about things like politics.

Nor can a high IQ protect you from the sunk cost bias -- the tendency to throw more resources into a failing project, even if it would be better to cut your losses -- a serious issue in any business. (This was, famously, the bias that led the British and French governments to continue funding Concorde planes, despite increasing evidence that it would be a commercial disaster.) Highly intelligent people are also not much better at tests of "temporal discounting", which require you to forgo short-term gains for greater long-term benefits. That's essential, if you want to ensure your comfort for the future.

Besides a resistance to these kinds of biases, there are also more general critical thinking skills -- such as the capacity to challenge your assumptions, identify missing information, and look for alternative explanations for events before drawing conclusions. These are crucial to good thinking, but they do not correlate very strongly with IQ, and do not necessarily come with higher education. One study in the USA found almost no improvement in critical thinking throughout many people's degrees. Given these looser correlations, it would make sense that the rise in IQs has not been accompanied by a similarly miraculous improvement in all kinds of decision making.

The article concludes that "this kind of thinking can be taught -- but it needs deliberate and careful instruction," and suggests "we might also make a more concerted and deliberate effort to improve those other essential skills too that do not necessarily come with a higher IQ..."

"Ideally, we might then start to see a steep rise in rationality -- and even wisdom... If so, the temporary blip in our IQ scores need not represent the end of an intellectual golden age -- but its beginning."

Amazon's Alexa Will Deliver NHS Medical Advice in the UK (theverge.com) 45

"The UK's National Health Service (NHS) has announced what it claims is a world first: a partnership with Amazon's Alexa to offer health advice from the NHS website."

An anonymous reader quotes the Verge: Britons who ask Alexa basic health questions like "Alexa, how do I treat a migraine?" and "Alexa, what are the symptoms of flu?" will be given answers vetted by NHS health professionals and currently available on its website. At the moment, Alexa sources answers to such questions from a variety of places, including the Mayo Clinic and WebMD.

The partnership does not add significantly to Alexa's skill-set, but it is an interesting step for the NHS. The UK's Department of Health (DoH) says it hopes the move will reduce the pressure on health professionals in the country, giving people a new way to access reliable medical advice. It will also benefit individuals with disabilities, like sight impairments, who may find it difficult to use computers or smartphones to find the same information.
