World's First Floating Windfarm To Take Shape Off Coast of Scotland (theguardian.com)

An anonymous reader quotes a report from The Guardian: The world's first floating windfarm has taken to the seas in a sign that a technology once confined to research and development drawing boards is finally ready to unlock expanses of ocean for generating renewable power. After two turbines were floated this week, five now bob gently in the deep waters of a fjord on the western coast of Norway ready to be tugged across the North Sea to their final destination off north-east Scotland. The ~$256 million Hywind project is unusual not just because of the pioneering technology involved, which uses a 78-meter-tall underwater ballast and three mooring lines that will be attached to the seabed to keep the turbines upright. It is also notable because the developer is not a renewable energy firm but Norway's Statoil, which is looking to diversify away from carbon-based fuels.

New Study Confirms the Oceans Are Warming Rapidly (theguardian.com) 274

An anonymous reader shares a report from The Guardian, written by John Abraham, who discusses the rising ocean temperatures and the important factors that affect ocean-temperature accuracy: The most important measurement of global warming is in the oceans. In fact, "global warming" is really "ocean warming." If you are going to measure the changing climate of the oceans, you need to have many sensors spread out across the globe that take measurements from the ocean surface to the very depths of the waters. Importantly, you need to have measurements that span decades so a long-term trend can be established. These difficulties are tackled by oceanographers, and a significant advancement was presented in a paper just published in the journal Climate Dynamics. That paper, which I was fortunate to be involved with, looked at three different ocean temperature measurements made by three different groups. We found that regardless of whose data was used or where the data was gathered, the oceans are warming. In the paper, we describe perhaps the three most important factors that affect ocean-temperature accuracy. First, sensors can have biases (they can be "hot" or "cold"), and these biases can change over time. Another source of uncertainty is related to the fact that we just don't have sensors at all ocean locations and at all times. Some sensors, which are dropped from cargo ships, are densely located along major shipping routes. Other sensors, dropped from research vessels, are also confined to specific locations across the globe. Finally, temperatures are usually referenced to a baseline "climatology." So, when we say temperatures have increased by 1 degree, it is important to say what the baseline climatology is. Have temperatures increased by 1 degree since the year 1990? Since the year 1970? Since 1900? The choice of baseline climatology really matters.

Physicists Have Created the Brightest Light Ever Recorded (vice.com) 95

Jason Koebler writes: A group of physicists at the University of Nebraska-Lincoln's Extreme Light Laboratory announced Monday that they have created the brightest light ever produced on Earth using Diocles, one of the most powerful lasers in the United States. When this high intensity laser pulse, which is one billion times brighter than the surface of the sun, strikes the electron, it causes it to behave differently. By firing this laser at individual electrons, the researchers found that past a certain threshold, the brightness of light will actually change an object's appearance rather than simply making it brighter. The x-rays that are produced in this fashion have an extremely high amount of energy, and Umstadter and his colleagues think this could end up being applied in a number of ways. For starters, it could allow doctors to produce x-ray medical images on the nanoscale, which would allow them to detect tumors and other anomalies that regular x-rays might have missed. Moreover, it could also be used for more sophisticated x-ray scanning at airports and other security checkpoints.

'Infarm' Startup Wants To Put a Farm In Every Grocery Store (techcrunch.com) 83

Infarm, a 40-plus person startup based in Berlin, imagines a future where every grocery store has its own farm packed with herbs, vegetables and fruit. "The plants themselves are being monitored by multiple sensors and fed by an internet-controlled irrigation and nutrition system," reports TechCrunch. "Growing out from the center, the basil is at ascending stages of its life, with the most outer positioned ready for you, the customer, to harvest." From the report: The concept might not be entirely new -- Japan has been an early pioneer in vertical farming, where the lack of space for farming and very high demand from a large population has encouraged innovation -- but what potentially sets Infarm apart, including from other startups, is the modular approach and go-to-market strategy it is taking. This means that the company can do vertical farming on a small but infinitely expandable scale, and is seeing Infarm place farms not in offsite warehouses but in customer-facing city locations, such as grocery stores, restaurants, shopping malls, and schools, enabling the end-customer to actually pick the produce themselves. In contrast, the Infarm system is chemical pesticide-free and can prioritize food grown for taste, color and nutritional value rather than shelf life or its ability to sustain mass production. Its indoor nature means it isn't restricted to seasonality either and by completely eliminating the distance between farmer and consumer, food doesn't get much fresher. When a new type of herb or plant is introduced, Infarm's plant experts and engineers create a recipe or algorithm for the produce type, factoring in nutrition, humidity, temperature, light intensity and spectrum, which is different from system to system depending on what is grown. The resulting combination of IoT, Big Data and cloud analytics is akin to "Farming-as-a-Service," whilst , space permitting, Infarm's modular approach affords the ability to keep adding more farming capacity in a not entirely dissimilar way to how cloud computing can be ramped up at the push of a button.

Sorry, But Anonymous Has No Evidence That NASA Has Found Alien Life (popsci.com) 145

From a Popular Science article: In a new video, the hacker group known as Anonymous claims that NASA has discovered alien life. But before you freak out, let's talk. Sadly, the group of activists and hacktivists doesn't seem to have found any new evidence to support their extraordinary claim. The video is mainly based on NASA quotes taken out of context, and what appear to be videos and information from conspiracy theory websites. The crux of the argument is based on something Thomas Zurbuchen, NASA's associate administrator for the Science Mission Directorate, said during a hearing in April. These sorts of hearings are organized to educate the House Science Committee on the latest research in a particular field of study. During this one, Zurbuchen said: "Taking into account all of the different activities and missions that are specifically searching for evidence of alien life, we are on the verge of making one of the most profound, unprecedented, discoveries in history." That's the quote Anonymous is pegging their video on. But if you watch his opening statement, he actually explains his reasoning just before he gets to that part. He mentions the Mars 2020 rover, which will look for signs of past life on the red planet. The Europa Clipper mission is slated to search for conditions suitable to life on Jupiter's ocean-filled moon. In a statement, Zurbuchen said, "While we're excited about the latest findings from NASA's Kepler space observatory, there's no pending announcement regarding extraterrestrial life. For years NASA has expressed interest in searching for signs of life beyond Earth. We have a number of science missions that are moving forward with the goal of seeking signs of past and present life on Mars and ocean worlds in the outer solar system. While we do not yet have answers, we will continue to work to address the fundamental question, 'are we alone?'"

The Mere Presence of Your Smartphone Reduces Brain Power, Study Shows (utexas.edu) 129

An anonymous reader shares a study: Your cognitive capacity is significantly reduced when your smartphone is within reach -- even if it's off. That's the takeaway finding from a new study from the McCombs School of Business at The University of Texas at Austin. McCombs Assistant Professor Adrian Ward and co-authors conducted experiments with nearly 800 smartphone users in an attempt to measure, for the first time, how well people can complete tasks when they have their smartphones nearby even when they're not using them. In one experiment, the researchers asked study participants to sit at a computer and take a series of tests that required full concentration in order to score well. The tests were geared to measure participants' available cognitive capacity -- that is, the brain's ability to hold and process data at any given time. Before beginning, participants were randomly instructed to place their smartphones either on the desk face down, in their pocket or personal bag, or in another room. All participants were instructed to turn their phones to silent. The researchers found that participants with their phones in another room significantly outperformed those with their phones on the desk, and they also slightly outperformed those participants who had kept their phones in a pocket or bag.

Anthem To Pay $115 Million In The Largest Data Breach Settlement Ever (cnet.com) 56

An anonymous reader quotes CNET: Anthem, the largest health insurance company in the U.S., has agreed to settle a class action lawsuit over a 2015 data breach for a record $115 million, according to lawyers for the plaintiffs. The settlement still has to be approved by US District Court Judge Lucy Koh, who is scheduled to hear the case on August 17 in San Jose, California. And Anthem, which didn't immediately respond to a request for confirmation and comment, isn't admitting any admitting any wrongdoing, according to a statement it made to CyberScoop acknowledging the settlement.

But if approved, it would be the largest data breach settlement in history, according to the plaintiffs' lawyers, who announced the agreement Friday. The funds would be used to provide victims of the data breach at least two years of credit monitoring and to reimburse customers for breach-related expenses. The settlement would also guarantee a certain level of funding for "information security to implement or maintain numerous specific changes to its data security systems, including encryption of certain information and archiving sensitive data with strict access controls," the plaintiff attorneys said.

The breach compromised data for 80 million people, including their social security numbers, birthdays, street addresses (and email addresses) as well as income data. The $115 million settlement averages out to $1.43 for every person who was affected.

SpaceX Livestreams Sunday's Rocket Launch (space.com) 74

An anonymous reader quotes Space.com: A SpaceX Falcon 9 rocket carrying the 10 satellites for Iridium Communications is scheduled to liftoff from Vandenberg Air Force Base in California at 1:25 p.m. PDT (4:25 p.m. EDT/2025 GMT). The live webcast is expected to begin about 1 hour before the opening of the launch window, and you can watch it on SpaceX's website, or at Space.com. This is the second of eight planned Iridium launches with SpaceX. The launches will deliver a total of 75 satellites into space for the $3 billion Iridium NEXT global communications network. "Iridium NEXT will replace the company's existing global constellation in one of the largest technology upgrades ever completed in space," according to a statement from Iridium. "It represents the evolution of critical communications infrastructure that governments and organizations worldwide rely upon to drive business, enable connectivity, empower disaster relief efforts and more."
After the mission the booster rocket will attempt to land on a droneship. The droneships name is "Just Read The Instructions."

FCC Grants OneWeb Approval To Launch Over 700 Satellites For 'Space Internet' (theverge.com) 89

OneWeb has been granted approval from the FCC to launch a network of internet-beaming satellites into orbit. FCC chairman Ajit Pai said in a statement: "Humans have long sought inspiration from the stars, from the ancient Egyptians orienting the pyramids toward certain stars to the Greeks using constellations to write their mythology. In modern times, we've done the same, with over 1,000 active satellites currently in orbit. Today, the FCC harnesses that inspiration as we seek to make the promise of high-speed internet access a reality for more Americans, partly through the skies..." The Verge reports: OneWeb plans to launch a constellation of 720 low-Earth orbit satellites using non-geostationary satellite orbit (NGSO) technology in order to provide global, high-speed broadband. The company's goal has far-reaching implications, and would provide internet to rural and hard-to-reach areas that currently have little access to internet connectivity. Additionally, OneWeb has a targets of "connecting every unconnected school" by 2022, and "bridging the digital divide" by 2027. According to OneWeb, the company plans to launch an initial 10 production satellites in early 2018, which, pending tests, will then be followed by a full launch as early as 2019.

'Chiropractors Are Bullshit' (theoutline.com) 323

From an article on The Outline, submitted by two readers: If you're one of the approximately 80 percent of Americans who have suffered from back pain, you may have been referred to a chiropractor for medical help. In the modern-day internet landscape, you'll find chiropractic celebrities like Dr. Josh Axe (1.7 million Facebook followers), Dr. Billy DeMoss (20,000 Facebook followers), and Dr. Eric Berg (472,000 YouTube subscribers) giving advice that goes beyond managing spinal issues. Both in their offices and on social media, chiropractors have adapted to a marketplace that's demanding more than just pain management: they extol the virtues of an "alkaline diet," tell you how to manage stress with detoxing, and wax scientific about the adrenal gland. [...] Chiropractic care, I'm sorry to say, is little more than the buffoonery of a 19th-century lunatic who derived most of his medical theory from seances. It has not evolved much since its creation. Chiropractic beliefs are dangerously far removed from mainstream medicine, and the vocation's practices have been linked to strokes, herniated discs, and even death. Chiropractors can't replace your doctor, and I'm amazed that they're still even allowed to practice. [...] Though some chiropractors are now making an effort to introduce evidence-based practices into their treatment, chiropractic as a whole hasn't evolved like other areas of medicine -- with hypotheses, experimentation, and peer review. Instead, it was birthed by a strange combination of hocus pocus, guesswork, and strongly held religious beliefs.

SpaceX Successfully Launches and Lands a Used Rocket For the Second Time (theverge.com) 74

SpaceX has successfully launched and landed a recycled Falcon 9 rocket for the second time. "The rocket's first stage -- the 14-story-tall core that houses the fuel and the rocket's main engines -- touched down on one of the company's autonomous drone ships in the Atlantic Ocean shortly after taking off from a launchpad at nearby Cape Canaveral, Florida," reports The Verge. From the report: This particular rocket previously flew in January, when it was used to put 10 satellites into orbit for communications company Iridium. The rocket then landed on a drone ship in the Pacific Ocean. SpaceX retrieved the rocket and spent the next few months refurbishing it in preparation for today's launch. This afternoon, it was used to launch Bulgaria's first communications satellite for TV service provider Bulsatcom. The landing wasn't easy, though. Because the rocket had to push BulgariaSat-1 to such a high orbit, the first stage experienced more force and heat during reentry than any other Falcon 9, according to a tweet from SpaceX CEO Elon Musk. Musk even warned that there was a "good chance [the] rocket booster doesn't make it back." Shortly after the landing, though, Musk returned to Twitter to add that the rocket booster used "almost all of the emergency crush core," which helps soften the landing.

ESA Approves Gravitational-Wave Hunting Spacecraft For 2034 (newscientist.com) 49

The European Space Agency has approved the Laser Interferometer Space Antenna mission designed to study gravitational waves in space. The spacecraft is slated for launch in in 2034. New Scientist reports: LISA will be made up of three identical satellites orbiting the sun in a triangle formation, each 2.5 million kilometers from the next. The sides of the triangle will be powerful lasers bounced to and fro between the spacecraft. As large objects like black holes move through space they cause gravitational waves, ripples which stretch and squeeze space-time. The LISA satellites will detect how these waves warp space via tiny changes in the distance the laser beams travel. In order to detect these minuscule changes, on scales less than a trillionth of a meter, LISA will have to shrug off cosmic rays and the particles and light from the sun. The LISA Pathfinder mission, a solo probe launched in December 2015, proved that this sensitivity was possible and galvanized researchers working to realize the full LISA mission.

Scientists Discover How To Stop Luggage From Toppling On the Race Through the Airport (theguardian.com) 182

An anonymous reader quotes a report from The Guardian: Scientists have worked out why suitcases tend to to rock violently from one wheel to the other until they overturn on the race through the airport. This most pressing of modern mysteries was taken on by physicists in Paris, who devised a scale model of a two-wheeled suitcase rolling on a treadmill and backed up their observations with a pile of equations and references to holonomic restraints, finite perturbations and the morphing of bifurcation diagrams. Fortunately for non-physicists, the findings can be reduced to simpler terms. For the suitcase to rock it had to hit a bump or be struck in some other manner; the faster the suitcase was being pulled, the more minor the bump needed to set it off. So far, so obvious. But Sylvain Courrech du Pont wanted to know more. Why did a rocking suitcase swerve and make such violent movements that it might eventually topple over? After more treadmill tests and more equations, the answer popped up: because a suitcase's handle pulls from the middle and the wheels are at its sides, the suitcase swerves inwards whenever it tilts up on one wheel. If the rocking overcomes the dampening effect that happens when each wheel touches the ground again, the suitcase will keep on rocking or eventually flip over. In conclusion, the researchers discovered that "when a suitcase starts to rock out of control, the correct response is not to slow down but to pull it faster." The scientists have published their findings in the journal Proceedings of the Royal Society.

Stephen Hawking Says He Is Convinced That Humans Need To Leave Earth (sciencealert.com) 389

Reader dryriver writes: Back in May, renowned physicist Stephen Hawking made yet another doomsday prediction. He said that humanity has 100 years left on Earth, which knocked 900 years off the prediction he made in November 2016, which had given humanity 1,000 years left. With his new estimate, Hawking suggested the only way to prolong humanity's existence is for us to find a new home, on another planet (alternative source). Speaking at the Starmus Festival in Trondheim, Norway on Tuesday, Hawking reiterated his point: "If humanity is to continue for another million years, our future lies in boldly going where no one else has gone before," he explained, according to the BBC. Specifically, Hawking said that we should aim for another Moon landing by 2020, and work to build a lunar base in the next 30 years -- projects that could help prepare us to send human beings to Mars by 2025. "We are running out of space and the only places to go to are other worlds. It is time to explore other solar systems. Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth," Hawking added.

Curiosity Rover Decides, By Itself, What To Investigate On Mars (sciencemag.org) 73

sciencehabit writes: NASA's Curiosity rover landed on Mars in 2012, in part to analyze rocks to see whether the Red Planet was ever habitable (or inhabited). But now the robot has gone off script, picking out its own targets for analysis -- precisely as planned. Last year, NASA scientists uploaded a piece of software called Autonomous Exploration for Gathering Increased Science (AEGIS) adapted from the older Opportunity rover. Curiosity can now scan each new location and use artificial intelligence to find promising targets for its ChemCam. Compared with the estimated 24% success rate of random aiming at picking out outcrops -- a prime target for investigation -- the current version of AEGIS lets the rover find them 94% of the time, researchers report.

Study Finds Yoga Works As Well As Physical Therapy For Back Pain (time.com) 164

An anonymous reader quotes a report from TIME: Another study is touting the benefits of yoga -- this time, for people with back problems. The new research put yoga head-to-head against physical therapy and found the two were equally good at restoring function and reducing the need for pain medication over time. In the new study, published in Annals of Internal Medicine, a group of 320 people did 12 weeks of yoga or physical therapy, or they simply received a book and newsletters about coping with back pain. People in the active treatment groups reported that their pain was less intense than it was at the start of the study and that they were able to physically move more. Some were also able to reduce, or even stop, their pain medications. Those improvements stuck around for a full year after the study was over. This research is unique because the people in the study were racially diverse, and most were from low-income families. Many had pre-existing medical conditions. That's important, say the researchers, because chronic back pain -- which affects about 10% of U.S. adults -- has a greater impact on minorities and people of lower socioeconomic status.

Sweden Passes Bill To Become Carbon Neutral By 2045 (newscientist.com) 226

Sweden is the first country to significantly upgrade its carbon ambitions since the Paris accord in 2015. The country has passed a new bill committing to cut its net carbon emissions to zero by 2045. New Scientist reports: The law was drawn up by a cross-party committee and passed with an overwhelming majority in parliament by 254 votes to 41. The legislation establishes an independent Climate Policy Council and requires an action plan to be updated every four years. Sweden had previously committed to becoming carbon neutral by 2050. It already gets 83 per cent of its electricity from nuclear energy and hydropower, having met its 2020 target of 50 per cent renewable energy eight years ahead of schedule. To achieve carbon-neutral status, the country will focus on reducing emissions from transport by increasing the use of biofuels and electric vehicles. It plans to cut domestic emissions by at least 85 per cent, and offset remaining emissions by planting trees or investing in projects abroad.

It's Too Hot For Some Planes To Fly In Phoenix (npr.org) 286

In Phoenix on Tuesday, temperatures were forecast to climb as high as 120 degrees Fahrenheit, causing more than 40 American Eagle regional flights out of Phoenix's international airport to be canceled. NPR reports: American Airlines said in a statement that the Bombardier CRJ aircraft used on some shorter routes have a maximum operating temperature of 118 degrees. For bigger jets, the threshold is higher. The carrier says that, for example, Airbus aircraft have a maximum operating temperature of 127 degrees and that for Boeing, it is 126 degrees. As USA Today reports: "Extreme heat affects a plane's ability to take off. Hot air is less dense than cold air, and the hotter the temperature, the more speed a plane needs to lift off. A runway might not be long enough to allow a plane to achieve the necessary extra speed." Bianca Hernandez, a meteorologist with the National Oceanic and Atmospheric Administration, tells NPR that Phoenix is seeing an unusually strong high-pressure system, which is causing the soaring temperatures.

'Older Fathers Have Geekier Sons' (bbc.com) 145

An anonymous reader shares a BBC article: Men who delay starting a family are more likely to have "geekier" sons, a study suggests. They were brighter, more focused and less bothered about fitting in -- according to the "Geek Index" devised by King's College London. The mother's age had no impact, and daughters seemed to be immune. One scientist said a trend for delayed parenthood might mean we were heading towards a "society of geniuses" able to solve the world's problems. The findings are rare good news in the science of delayed fatherhood. Repeated studies have shown that older sperm is more prone to genetic errors and children are more likely to develop autism and schizophrenia.
