Submission + - U.S. Navy Scientist Files Room-Temperature Superconductor Patent Application (phys.org)

Submitted by resistant
resistant writes: Potentially interesting news popped up this week on the room-temperature superconductor research front, courtesy of Phys.org :

A scientist working for the U.S. Navy has filed for a patent on a room-temperature superconductor, representing a potential paradigm shift in energy transmission and computer systems.

Salvatore Cezar Pais is listed as the inventor on the Navy's patent application made public by the U.S. Patent and Trademark Office on Thursday.

The application claims that a room-temperature superconductor can be built using a wire with an insulator core and an aluminum PZT (lead zirconate titanate) coating deposited by vacuum evaporation with a thickness of the London penetration depth and polarized after deposition.

An electromagnetic coil is circumferentially positioned around the coating such that when the coil is activated with a pulsed current, a non-linear vibration is induced, enabling room temperature superconductivity.

However, NextBigFuture says the same individual appears to have made other startling claims that arguably stretch the boundaries of belief, such as a "high-frequency gravitational wave generator" that could supposedly drive a spaceship without conventional propellants as well as an "inertial mass reduction device." Prudence would appear to dictate examining these and other claims by Mr. Salvatore Cezar Pais with great caution.

Submission + - Doctor Who won't return until 2020 (bbc.co.uk) 1

Submitted by AmiMoJo
AmiMoJo writes: The next series of Doctor Who won't start until 2020, it's been confirmed. Series 11 ended on Sunday night, but after the festive special on New Year's Day, Jodie Whittaker won't be seen in the Tardis again next year.

Showrunner Chris Chibnall said work on the new series had already begun. The first episode of the series, the first to feature a female Doctor, drew a record audience. It saw the highest launch viewing figures for the sci-fi stalwart in a decade, with 10.9 million people tuning in. The series has been considered a ratings success, with viewing figures above those of the last two series when Peter Capaldi starred in the title role.

Submission + - Warming Arctic May Provide Minor Carbon Sink (phys.org)

Submitted by DavidHumus
DavidHumus writes: Interesting study here of two major Arctic rivers posits that "...40 years of climate change seem to have fortified a natural process that consumes and stores atmospheric carbon dioxide."

It seems that the weathering of rocks locks up CO2 from the atmosphere into stable salts "...that can be geologically stored for millennia."

While the effect in the Arctic is not nearly large enough to counter-balance anthropogenic CO2 emissions, it illustrates some of the dynamics of the global carbon cycle.

Audius Raises $5.5 Million To Decentralize Music, Help Artists Get Paid Faster (techcrunch.com) 65

Posted by BeauHD from the blockchain-friendly dept.
A new company called Audius, lead by entrepreneur and DJ Ranidu Lankage, has raised $5.5 million to build a blockchain-based alternative to Spotify or SoundCloud. "Users will pay for Audius tokens or earn them by listening to ads," reports TechCrunch. "Their wallet will then pay out a fraction of a cent per song to stream from decentralized storage across the network, with artists receiving roughly 85 percent -- compared to roughly 70 percent on the leading streaming apps. The rest goes to compensating whomever is hosting that song, as well as developers of listening software clients, one of which will be built by Audius." From the report: Audius plans to launch its open-sourced product in beta later this year. But it's already found some powerful investors that see SoundCloud as vulnerable to the cryptocurrency revolution. Audius has raised a $5.5 million Series A led by General Catalyst and Lightspeed, with participation from Kleiner Perkins, Pantera Capital, 122West and Ascolta Ventures. They're betting that Audius' token will grow in value, making the stockpile it keeps worth a fortune. It could then sell chunks of its tokens to earn revenue instead of charging artists directly. The big question will be whether Audius can use the token economy to crack the chicken-and-egg problem of getting its first creators and listeners on a platform that might be less functionally robust than its traditional competitors. There are a lot of moving parts to decentralize, but there are also plenty of disgruntled musicians out there waiting for something better.

Engineers Teach a Drone To Herd Birds Away From Airports Autonomously (techxplore.com) 47

Posted by BeauHD from the clever-thinking dept.
An anonymous reader quotes a report from Tech Xplore: Engineers at Caltech have developed a new control algorithm that enables a single drone to herd an entire flock of birds away from the airspace of an airport. The algorithm is presented in a study in IEEE Transactions on Robotics. Herding relies on the ability to manage a flock as a single, contained entity -- keeping it together while shifting its direction of travel. Each bird in a flock reacts to changes in the behavior of the birds nearest to it. Effective herding requires an external threat -- in this case, the drone -- to position itself in such a way that it encourages birds along the edge of a flock to make course changes that then affect the birds nearest to them, who affect birds farther into the flock, and so on, until the entire flock changes course. The positioning has to be precise, however: if the external threat gets too zealous and rushes at the flock, the birds will panic and act individually, not collectively.

To teach the drone to herd autonomously, Soon-Jo Chung, an associate professor of aerospace, and his colleagues [...] studied and derived a mathematical model of flocking dynamics to describe how flocks build and maintain formations, how they respond to threats along the edge of the flock, and how they then communicate that threat through the flock. Their work improves on algorithms designed for herding sheep, which only needed to work in two dimensions, instead of three. Once they were able to generate a mathematical description of flocking behaviors, the researchers reverse engineered it to see exactly how approaching external threats would be responded to by flocks, and then used that information to create a new herding algorithm that produces ideal flight paths for incoming drones to move the flock away from a protected airspace without dispersing it. The team tested the algorithm on a flock of birds near a field in Korea and found that a single drone could keep a flock of dozens of birds out of a designated airspace. The effectiveness of the algorithm is only limited by the number and size of the incoming birds.

New York City Just Voted To Cap Uber and Lyft Vehicles and Require Drivers To Be Paid a Minimum Wage (cnbc.com) 247

Posted by msmash from the taking-a-stand dept.
New York City Council passed regulations on ride-hail companies on Wednesday, capping the number of vehicles on the road for one year and requiring that drivers to be paid a minimum wage. From a report: Council Speaker Corey Johnson said earlier that the regulations are intended to protect drivers, fairly regulate the industry and reduce congestion. The year-long cap on new licenses for ride-hailing vehicles will take place while the Taxi and Limousine Commission (TLC) studies the effects of ride-hail service in the city. The cap would not apply to new wheelchair-accessible vehicles or new vehicles serving an area demonstrating need in a way that does not increase congestion. App-based ride services account for 80,000 vehicles in New York City, and provide 17 million rides per month, according to a study by The New School for the TLC. The surge in ridership coincided with increased resident frustration with the local subway system. With the move on Wednesday, New York City, the largest American market for Uber, has become the first major American city to restrict the number of ride-hail vehicles and to establish pay rules for drivers. In a statement issued moments ago, New York Mayor Bill de Blasio said," Our city is directly confronting a crisis that is driving working New Yorkers into poverty and our streets into gridlock. The unchecked growth of app-based for-hire vehicle companies has demanded action -- and now we have it."

Submission + - Pentagon debuts artificial intelligence hub

Submitted by Lasrick
Lasrick writes: The Pentagon’s new Joint Artificial Intelligence Center (JAIC) will accelerate the delivery of AI-enabled capabilities, scale the impact of AI tools, and synchronize the Defense Department’s AI efforts. To this end, JAIC will guide the execution of so-called National Mission Initiatives—large-scale AI projects “designed to address groups of urgent, related challenges.” Interestingly, one of JAIC’s core mandates is to work with the Office of the Secretary of Defense to develop standards and a governance framework for AI development and delivery. This specific dimension of JAIC, though its parameters remain abstract for now, could play an important role in realizing the Pentagon’s AI ambitions, as AI researchers and companies might be more willing to collaborate with the Pentagon if it were to establish transparent guidelines for the development and deployment of AI systems.

P2P Piracy is Alive and Growing, Research Suggests (torrentfreak.com) 104

Posted by msmash from the closer-look dept.
From a report: In recent years Hollywood and other entertainment sources have focused their enforcement efforts on pirate streaming sites and services. According to several reports, streaming sites get more traffic than their P2P counterparts, with the latter being almost exclusively BitTorrent related. While the rise of online streaming sites can't be denied, a new research report from anti-piracy outfit Irdeto shows that P2P remains very relevant. In fact, it's still the dominant piracy tool in many countries. Irdeto researched site traffic data provided by an unnamed web analytics partner. The sample covers web traffic to 962 piracy sites in 19 countries where P2P was most used. This makes it possible to see how P2P site visits compare to those of pirate streaming sites.

People Still Don't Like Their Cable Companies, ConsumerReports' Telecom Survey Finds (consumerreports.org) 116

Posted by msmash from the closer-look dept.
Larger cable providers once again take a beating for perceived value -- even when it comes to bundled plans. ConsumerReports: Unhappy with your pay-TV company? You're not alone. Dissatisfaction with the perceived value of pay-TV service was once again high among the 176,000 members who participated in Consumer Reports' latest telecommunications survey. When we asked for feedback on their experiences with pay TV, home internet, home telephone service, and bundled plans, they shared their displeasure. In fact, most of the larger cable companies -- Optimum (Cablevision), Comcast, and Spectrum (Charter, Time Warner Cable, Bright House Networks) -- earned low scores in multiple categories, settling into the bottom half of the 25 providers in CR's new telecom service ratings.

Only 38 percent of pay-TV subscribers were highly satisfied with their service, meaning they were "very" or "completely" happy with the offerings. Armstrong, a smaller cable company that operates in Kentucky, Maryland, New York, Ohio, Pennsylvania, and West Virginia, earned the second-place slot behind Google Fiber, in part due to favorable scores for technical support, reliability, and customer service. Verizon and the two satellite-TV companies -- AT&T's DirecTV and Dish Network -- also rated better than Cox Communications, Comcast, Spectrum, and Optimum.

Top-rated EPB, a municipal broadband service run as a public utility in Chattanooga, Tenn., was one of the few bright spots for internet service. It was the only company to receive a top mark for value. It also got top marks for speed and reliability. Google Fiber was a close second in the ratings, the only other company to get a favorable mark for value.

Nearly three-quarters of the survey respondents who have a bundled plan -- TV, internet, and phone -- said they got a special promotional price when they signed up. And 45 percent were still enjoying that rate when they answered our survey.

New Facial Recognition Tool, Designed For Research Purposes, Tracks Targets Across Different Social Networks (theverge.com) 42

Posted by msmash from the on-face-value dept.
Researchers at Trustwave on Wednesday released a new open-source tool called Social Mapper, which uses facial recognition to track subjects across social media networks. Designed for security researchers performing social engineering attacks, the system automatically locates profiles on Facebook, Instagram, Twitter, LinkedIn, and other networks based on a name and picture. Unlike tools such as Geofeedia that require access to certain APIs, Social Mapper performs automated manual searches in an instrumented browser window. The Verge: Those searches can already be performed manually, but the automated process means it can be performed far faster and for many people at once. "Performing intelligence gathering online is a time-consuming process," Trustwave explained in a post this morning. "What if it could be automated and done on a mass scale with hundreds or thousands of individuals?"

When Working in Virtual Reality Makes You Sick (medium.com) 73

Posted by msmash from the closer-look dept.
Virtual reality is a modern-day beacon of escapism -- a way to fully immerse yourself in other worlds -- and it's seeing unprecedented applications. The market, no surprise, is exploding, with some industry groups estimating a $60 billion global market by 2022. As business booms, however, people who are using the tech are reporting a growing number of physical side effects -- like VR arm, but worse: eye strain, dizziness, headaches, nausea, and even dissociative experiences. From a report: VR companies recommend that people take frequent breaks and moderate their VR time when they're first starting out. "As you become accustomed to the virtual reality experience, you can begin increasing the amount of time you use Daydream View," reads one line of the health and safety information included with Google's VR platform. But what happens when it's your job to build these escapist technologies? The potential health risks for everyday consumers are compounded for those who make VR products for a living.

When VR bigwig Jeremy Bailenson founded Stanford University's Virtual Human Interaction Lab, in 2003, two items were even more important than the VR equipment he was using: "We had to keep a bucket in the lab and a mop nearby," Bailenson says. Today, he institutes a strict 20-minute limit on headset time for people in his lab. These health effects produce unique challenges for VR developers. "We have to understand not just the good but also the downsides of this technology. There a lot of questions we need to answer," Bailenson says. "The whole point of VR is it takes you out of your space, but you can't be doing that for many hours a day."

[...] Suddenly rotating around a virtual environment using handled controllers or quickly looking left and right in the VR space without any concomitant physical movement in the real world tend to physically affect Jonathan Yomayuza, VR technical director at the Emblematic Group, a creative firm based in Southern California. [...] The feeling Yomayuza describes is common among people who work with or use VR.

Submission + - 538 releases data set with ~3 million Russian troll tweets (fivethirtyeight.com)

Submitted by Layzej
Layzej writes: Last week, FiveThirtyEight published nearly 3 million tweets sent by handles affiliated with the Internet Research Agency, a Russian “troll factory.” That group was a defendant in one of special counsel Robert Mueller’s indictments, which accused the IRA of interfering with American electoral and political processes.

Since the release, 538 has compiled a sampling of reader projects that utilize the data set. The projects reinforce and expand upon the Clemson researchers’ initial finding: The trolls were engaged in a sophisticated and intricate Russian assault on the political debate in America and several other countries. It was an assault waged both before and after the 2016 presidential election — and an assault that appears to continue, at least in some form, to this day.

The data set is available on github.
