Researchers Create Algorithm That Diagnoses Depression From Your Instagram Feed (inverse.com)

An anonymous reader quotes a report from Inverse: Harvard University's Andrew Reece and the University of Vermont's Chris Danforth crafted an algorithm that can correctly diagnose depression, with up to 70 percent accuracy, based on a patient's Instagram feed alone. After a careful screening process, the team analyzed almost 50,000 photos from 166 participants, all of whom were Instagram users and 71 of whom had already been diagnosed with clinical depression. Their results confirmed their two hypotheses: first, that "markers of depression are observable in Instagram user behavior," and second, that "these depressive signals are detectable in posts made even before the date of first diagnosis." The duo had good rationale for both hypotheses. Photos shared on Instagram, despite their innocent appearance, are data-laden: Photos are either taken during the day or at night, in- or outdoors. They may include or exclude people. The user may or may not have used a filter. You can imagine an algorithm drooling at these binary inputs, all of which reflect a person's preferences, and, in turn, their well-being. Metadata is likewise full of analyzable information: How many people liked the photo? How many commented on it? How often does the user post, and how often do they browse? Many studies have shown that depressed people both perceive less color in the world and prefer dark, anemic scenes and images. The majority of healthy people, on the other hand, prefer colorful things. [Reece and Danforth] collected each photo's hue, saturation, and value averages. Depressed people, they found, tended to post photos that were more bluish, unsaturated, and dark. "Increased hue, along with decreased brightness and saturation, predicted depression," they write. The researchers found that happy people post less than depressed people, happy people post photos with more people in them than their depressed counterparts. and that depressed participants were less likely to use filters. The majority of "healthy" participants chose the Valencia filter, while the majority of "depressed" participants chose the Inkwell filter. Inverse has a neat little chart embedded in their report that shows the usage of Instagram filters between depressed and healthy users.

Canon Unveils EOS 5D Mark IV DSLR (canonrumors.com) 57

It's been a little more than 4 year since Canon unveiled the EOS 5D Mark III. Today, Canon took the wraps off its successor -- the EOS 5D Mark IV. The Mark IV features a 34-megapixel, full-frame CMOS sensor and Digic 6+ processor with support for capturing 4K video at 23.98, 24, 25 and 30 fps. In addition, it features a 61-point autofocus system, built-in digital lens optimizer, NFC, Wi-Fi and an ISO range of 100-32,000. The continuous shooting mode is set at 7 fps, compared to 6 fps on the 5D Mark III. It will also take both CompactFlash and SD cards, and there is GPS included in the body for geotagging images. Canon is selling the Mark IV in early September for $3,499 for the body only. They're also selling two new L-series EF lenses -- the Canon EF 16-35mm f/2.8L III USM Ultra-Wide Zoom Lens and EF 24-105mm f/4L IS II USM Standard Zoom Lens. President and COO, Canon U.S.A., Inc, Yichi Ishizuka said in a statement: "Canon's EOS 5D series of DSLR cameras has a history of being at the forefront of still and video innovation. And today, we add to this family of cameras the EOS 5D Mark IV -- the first in our 5D series to offer 4K video and built-in Wi-Fi and NFC connectivity. In developing this new DSLR camera, we listened to the requests of current EOS users to create for them a modern, versatile camera designed to help them create and share beautiful still and video imagery." Here's a blast from the past: Canon's EOS 1Ds Mark II. Slashdot reader LoudMusic submitted this story back in 2004, highlighting the camera's "802.11a/g and wired networking capabilities."

NASA Astronaut Jeff Williams Sets New US Space Endurance Record With 521 Days (cbsnews.com) 27

An anonymous reader quotes a report from CBS News: Space station commander Jeff Williams set a new U.S. space endurance record Wednesday, his 521st day in orbit over four missions, eclipsing the 520-day record set earlier this year by astronaut Scott Kelly at the end of his nearly one-year stay aboard the lab complex. Williams now moves up to 17th on the list of the world's most experienced astronauts and cosmonauts. The overall record is held by cosmonaut Gennady Padalka, who logged 878 days in orbit over five missions. Williams, Soyuz TMA-20M commander Alexey Ovchinin and flight engineer Oleg Skripochka were launched to the space station March 18. They plan to return to Earth Sept. 6 (U.S. time), landing in Kazakhstan to close out a 172-day mission. At landing, Williams will have logged 534 days aloft, moving him up to 14th on the space endurance list. Williams first flew in space in 2000 aboard the shuttle Atlantis, the third shuttle flight devoted to station assembly. He served as a flight engineer aboard the station in 2006 and completed a second long-duration stay in 2010, serving as a flight engineer and then commander of Expedition 22. "I wanted to congratulate you on passing me up here in total number of days in space," Kelly radioed Williams Wednesday. "It's great to see another record broken. [...] But I do have one question for you. And my question is, do you have another 190 days in you?" Kelly was referring to the time Williams' current mission would have to be extended to equal Kelly's U.S. single-flight record. Williams laughed, saying "190 days. That question's not for me, that's for my wife!"

Global Warming Started 180 Years Ago Near Beginning of Industrial Revolution, Says Study (smh.com.au) 238

New research led by scientists at the Australian National University's Research School of Earth suggests that humans first started to significantly change the climate in the 1830s, near the beginning of the Industrial Revolution. The findings have been published in the journal Nature, and "were based on natural records of climate variation in the world's oceans and continents, including those found in corals, ice cores, tree rings and the changing chemistry of stalagmites in caves." Sydney Morning Herald reports: "Nerilie Abram, another of the lead authors and an associate professor at the Australian National University's Research School of Earth Sciences, said greenhouse gas levels rose from about 280 parts per million in the 1830s to about 295 ppm by the end of that century. They now exceed 400 ppm. Understanding how humans were already altering the composition of the atmosphere through the 19th century means the warming is closer to the 1.5 to 2 degrees target agreed at last year's Paris climate summit than most people realize." "It was one of those moments where science really surprised us," says Abram. "But the results were clear. The climate warming we are witnessing today started about 180 years ago."

'Octobot' Is The World's First Soft-Bodied Robot (sciencemag.org) 32

sciencehabit quotes a report from Science Magazine: Researchers have created the first completely soft-bodied robot, dubbed the 'octobot.' The palm-sized machine's exterior is made of silicone. And whereas other soft robots have had at least a few hard parts, such as batteries or wires, the octobot uses a small reservoir of hydrogen peroxide as fuel. The basic design can be scaled up or down, increasing or decreasing fuel capacity depending on the robot's job. As the field of soft robotics advances, the scientists envision these robots being used for marine search and rescue, oceanic temperature sensing, and military surveillance. The report adds: "When the hydrogen peroxide washes over flecks of platinum embedded within the octobot, the resulting chemical reaction produces gas that inflates and flexes the robot's arms. As described online today in Nature, the gas flows through a series of 3D-printed pneumatic chambers that link the octobot's eight arms; their flexing propels it through water."

'Legalist' Startup Automates The Lawsuit Strategy Peter Thiel Used To Bankrupt Gawker (gizmodo.com) 136

An anonymous reader writes from a report via Gizmodo: "Two Harvard undergraduates have created a service called Legalist that uses what they call 'data-backed litigation financing,' analyzing civil lawsuits with an algorithm to predict case outcomes and determine which civil lawsuits are worth investing in," reports Gizmodo. The process is very similar to what billionaire Peter Thiel did when he secretly funded a lawsuit from Hulk Hogan against Gawker Media. "Legalist says it uses an algorithm of 58 different variables including, as [Legalist cofounder] Eva Shang told the Silicon Valley Business Journal, who the presiding judge is and the number of cases the judge is currently working on. The algorithm has been fed cases dating back to 1989 and helps people figure out how long a case will last and the risks associated with it. In a presentation at Y Combinator's Demo Day on Tuesday [Legalist was developed as part of Y Combinator's Summer 2016 class], the founders claimed that the startup funded one lawsuit for $75,000 and expects a return of more than $1 million. Shang says the $1.40 is earned for every $1 spent in litigation financing, which can prove to be a profitable enterprise when you're spending hundreds of thousands of dollars." Shang told Business Insider in reference to the Gawker lawsuit, "That's the kind of thing we're staying away from here." The company will supposedly be focusing on commercial and small-business lawsuits, and will not be backing lawsuits by individuals.

YouTube Plans To Bring Photos, Polls, and Text To Its Video Service (venturebeat.com) 18

An anonymous reader quotes a report from VentureBeat: YouTube is developing a feature internally called Backstage where users can share photos, polls, links, text posts, and videos with their subscribers. Backstage is expected to launch by the end of the year, possibly this fall, on mobile and desktop, initially with select popular YouTube accounts and with limited features, VentureBeat has learned. Akin to a Facebook Timeline or Twitter profile, Backstage will live alongside the Home and Videos tabs within individual YouTube channels. Posts shared to Backstage will appear in reverse chronological order, and, crucially, will also appear in subscribers' feeds and notifications, making them highly visible to fans. While Backstage is expected to introduce entirely new types of content to YouTube, including tweet-like text posts and topical polls, it also presents new opportunities for video sharing. Backstage will eventually enable users to share both traditional YouTube videos and Backstage-only videos, possibly creating an opportunity for more intimate, or even ephemeral, video sharing between YouTubers and their fans.

World's Largest Aircraft Crashes Its Second Flight (theverge.com) 120

Not too long after it completed its first test flight, the Airlander 10 -- the world's largest aircraft -- has crashed its second test flight. Since the 300-foot long aircraft contains 38,000 cubic meters of helium inside its hull, the crash was all but sudden. You can see in a video posted to YouTube from witnesses on the ground that the aircraft slowly descended to the ground, nose first. The BBC has published some close-up photos of the cockpit, which sustained damages. There were no injuries in the crash, according to a tweet from Hybrid Air Vehicles. The company did also deny eyewitness reports of the aircraft being damaged in a collision with a telegraph pole.

Self-Driving Cars Aren't Going To Be So Great Until We Make Our Maps Better (theverge.com) 104

Uber is debuting its self-driving cars in Pittsburgh this month, a move that has many taxi drivers upset. The Verge's Nilay Patel argues that this move should change the way we think about maps and addresses. He adds that Uber is currently unable to pinpoint his home, and often ends up at the door of a "widely different address." Citing the CEO of a "large ridesharing company", Patel writes that this issue is known as the "egress problem" -- "the way we locate buildings on a map doesn't really describe how people move in and out of those buildings." Though there are workarounds and inventive ways to pinpoint your exact address, Patel argues that when we grow reliant on self-driving cars, things will get far more complicated and futile if we don't make our maps and navigation services better. He writes: Driverless cars are one of the ultimate signifiers of the future -- the real Jetsons stuff. And we're so close to making them happen: tons of cars have sophisticated adaptive cruise control that can basically keep you going on the highway, prototypes of true self-driving cars from Google and others are already on the road, and the momentum is only increasing. But maybe we shouldn't hand control of how we get somewhere to the machines until we're entirely sure the robots know where we're going.

HP Hit With Age-Discrimination Suit Claiming Old Workers Purged (mercurynews.com) 140

Hewlett-Packard started laying off workers in 2012, before it separated into HP Inc. and HP Enterprise last year. The company has continued to cut thousands of jobs since. As a result of the "restructuring," an age discrimination lawsuit has been filed by four former employees of HP alleging they were ousted amid a purge of older workers. The Mercury News reports: "The goal 'was to make the company younger,' said the complain filed Aug. 18 in U.S. District Court in San Jose. 'In order to get younger, HP intentionally discriminated against its older employees by targeting them for termination [...] and then systematically replacing them with younger employees. HP has hired a disproportionately large number of new employees under the age of 40 to replace employees aged 40 and older who were terminated.' Arun Vatturi, a 15-year Palo Alto employee at HP who was a director in process improvement until he was laid off in January at age 52, and Sidney Staton, in sales at HP in Palo Alto for 16 months until his layoff in April 2015 at age 54, have joined in the lawsuit with a former employee from Washington, removed at age 62, and one from Texas, out at age 63. The group is seeking class-action status for the court action and claims HP broke state and federal laws against age discrimination." The lawsuit also alleges that written guidelines issued by HP's human resources department mandated that 75 percent of all hires outside of the company be fresh from school or "early career" applicants.

MIT Scientists Develop New Wi-Fi That's 330% Faster (msn.com) 62

An anonymous reader quotes a report from MSN: Scientists at MIT claim to have created a new wireless technology that can triple Wi-Fi data speeds while also doubling the range of the signal. Dubbed MegaMIMO 2.0, the system will shortly enter commercialization and could ease the strain on our increasingly crowded wireless networks. Multiple-input-multiple-output technology, or MIMO, helps networked devices perform better by combining multiple transmitters and receivers that work simultaneously, allowing then to send and receive more than one data signal at the same time. MIT's MegaMIMO 2.0 works by allowing several routers to work in harmony, transmitting data over the same piece of spectrum. MIT claimed that during tests, MegaMIMO 2.0 was able to increase data transfer speed of four laptops connected to the same Wi-Fi network by 330 percent. Paper co-author Rahul said the technology could also be applied to mobile phone networks to solve similar congestion issues. "In today's wireless world, you can't solve spectrum crunch by throwing more transmitters at the problem, because they will all still be interfering with one another," Ezzeldin Hamed, lead author on a paper on the topic, told MIT News. "The answer is to have all those access points work with each other simultaneously to efficiently use the available spectrum."

The US Army Has Too Many Video Games (vice.com) 80

An anonymous reader shares a Motherboard report:The US Army sees itself in a transitional period. Unlike a decade ago, soldiers are training less today on how to conduct "stability" operations for a counter-insurgency campaign, and more on what the Army does best: fighting other armies. But training is expensive and requires time and a lot of space. Training a gunner for an M-1 Abrams tank means reserving time on a limited number of ranges and expending real ammunition. So to lower costs and make training more efficient -- in theory -- the Army has adopted a variety of games to simulate war. There's just a few problems. Some of the Army's virtual simulators sit collecting dust, and one of them is more expensive and less effective than live training. At one base, soldiers preferred to play mouse-and-keyboard games over a more "realistic" virtual room. Then again, the Army has cooler games than you do. M-1 tank gunners, for example, can train inside a full-scale, computerized mock-up of their station called the Advanced Gunnery Training System, which comes inside a large transportable container. Instead of looking through real sights down a range, the soldier squints through a replica and sees a virtual simulacrum of, say, an enemy tank. Push a button and the "cannon" fires. The Army fields similar systems for the Stryker, a wheeled armored troop transport that fits an optional 105-millimeter gun. Soldiers train inside another simulated gunnery station for the M-2 Bradley fighting vehicle. Another system, Common Driver, simulates a variety of military vehicles.

Singapore To Cut Off Public Servants From the Internet (theguardian.com) 52

Singapore is planning to cut off web access for public servants as a defence against potential cyber attack, Reuters reports. The local government's move has already been criticized by many, who say that it marks a retreat for a technologically advanced city-state that has trademarked the term "smart nation". From an article on The Guardian: Some security experts say the policy, due to be in place by May, risks damaging productivity among civil servants and those working at more than four dozen statutory boards, and cutting them off from the people they serve. It may only raise slightly the defensive walls against cyber attack, they say. Ben Desjardins, director of security solutions at network security firm Radware, called it "one of the more extreme measures I can recall by a large public organisation to combat cyber security risks." Stephen Dane, a Hong Kong-based managing director at networking company Cisco Systems, said it was "a most unusual situation" and Ramki Thurimella, chair of the computer science department at the University of Denver, called it both "unprecedented" and "a little excessive".

Opera Brings Its Free VPN Service To Android (techcrunch.com) 25

Frederic Lardinois, writing for TechCrunch: Earlier this year, Opera launched its free and unlimited VPN service for iOS; today it is bringing the same functionality to Android. Like the iOS version, the Android app is based on Opera's acquisition of SurfEasy in 2015 and allows you to surf safely when you are on a public network. While Opera's marketing mostly focuses on safety, Opera VPN also allows you to appear as if you are in the U.S., Canada, Germany, Singapore and The Netherlands, so it's also a way to route around certain geo-restrictions without having to opt for a paid service. In addition to its VPN features, the service also allows you to block ad trackers. Somewhat ironically, though, the app itself will show you some pretty unintrusive ads. "The Opera VPN app for Android sets itself apart from other VPNs by offering a completely free service; without a data limit, no log-in required, advanced Wi-Fi protection features and no need for a subscription," says Chris Houston, the president of Opera's SurfEasy VPN division, in today's announcement.
