Submission + - How Airbnb Stopped Playing Nice (backchannel.com)

Submitted by mirandakatz
mirandakatz writes: For years, Airbnb was the friendly foil to Uber, aiming to work with cities rather than against them. But as it grew and regulatory challenges mounted, the startup had to grow fangs. In an excerpt from his latest book, Brad Stone details how Airbnb became every bit as controversial as Uber, writing that "Airbnb had said it wanted to talk candidly with cities, to play by the rules, to be a partner. But in the end, there emerged an unavoidable fact: Chesky was every bit the warrior Travis Kalanick was. He believed so much in the promise of his company that he was going to fight for every inch of territory."

Submission + - Secret Rules Make It Pretty Easy For the FBI To Spy On Journalists (theintercept.com)

Submitted by schwit1
schwit1 writes: Secret FBI rules allow agents to obtain journalists’ phone records with approval from two internal officials — far less oversight than under normal judicial procedures.

The classified rules dating from 2013, govern the FBI’s use of national security letters, which allow the bureau to obtain information about journalists’ calls without going to a judge or informing the news organization being targeted. They have previously been released only in heavily redacted form.

Submission + - 16 Years Of GPS Space Weather Data Made Publicly Available

Submitted by Anonymous Coward
An anonymous reader writes: Over 16 years of GPS space weather data has been released to the public for the first time, in a bid to help boost understanding around radiation threats to Earth’s satellites, communications networks, and aircraft. The ‘unprecedented’ collection of data, released by the Los Alamos National Laboratory, comes from space weather sensors onboard Global Positioning System (GPS) satellites, which measure charged particles in Earth’s magnetic field. The detailed measurements are expected to provide an invaluable resource for space weather research and for understanding how best to protect our critical infrastructure. Prior to the public release, GPS data has long remained a U.S. military asset, with a “general hesitancy to broadcast even fairly innocuous things out to the broad community.”

Submission + - Oxygen From Earth's Atmosphere May Be Traveling To the Moon's Surface (theverge.com)

Submitted by Anonymous Coward
An anonymous reader writes: New research shows that oxygen from Earth could be journeying all the way out to the Moon, where it then gets lodged inside the lunar soil. It’s a process that’s likely been happening for 2.4 billion years, ever since oxygen formed around our planet, meaning the Moon’s soil may contain trapped particles from Earth’s ancient atmosphere. This oxygen exchange, detailed in a study published today in Nature Astronomy, supposedly occurs for just a few days during the Moon’s 27-day orbit. Most of the time, the Moon is constantly being blasted with solar wind — fast streams of charged particles emanating from the Sun. But for five days of every lunar orbit, the Moon passes into Earth’s magnetotail, the portion of the planet’s magnetic field that stretches outward away from the Sun. This tail shields the Moon from the solar wind, and allows charged oxygen ions from Earth to travel to the lunar surface, according to the study. That means the Moon — a dead rock incapable of supporting life — is being showered with the byproducts of life here on Earth. In fact, the source of most of the oxygen in our atmosphere is biological, created by plants during photosynthesis. It’s a process that experts have suspected for a while but haven’t been able to confirm until today. Researchers have also suggested that other atmospheric components, such as nitrogen and noble gases, are getting to the Moon this way based on lunar soil samples.

Submission + - Scientists Find 'Oldest Human Ancestor' (bbc.com)

Submitted by Anonymous Coward
An anonymous reader writes: Researchers have discovered the earliest known ancestor of humans — along with a vast range of other species. They say that fossilized traces of the 540-million-year-old creature are "exquisitely well preserved." The microscopic sea animal is the earliest known step on the evolutionary path that led to fish and — eventually — to humans. Details of the discovery from central China appear in Nature journal. The research team says that Saccorhytus is the most primitive example of a category of animals called "deuterostomes" which are common ancestors of a broad range of species, including vertebrates (backboned animals). Saccorhytus was about a millimeter in size, and is thought to have lived between grains of sand on the sea bed. The researchers were unable to find any evidence that the animal had an anus, which suggests that it consumed food and excreted from the same orifice. The study was carried out by an international team of researchers, from the UK, China and Germany. Among them was Prof Simon Conway Morris, from the University of Cambridge. The study suggests that its body was symmetrical, which is a characteristic inherited by many of its evolutionary descendants, including humans. Saccorhytus was also covered with a thin, relatively flexible skin and muscles, leading the researchers to conclude that it moved by contracting its muscles and got around by wriggling. The researchers say that its most striking feature is its large mouth, relative to the rest of its body. They say that it probably ate by engulfing food particles, or even other creatures. Also interesting are the conical structures on its body. These, the scientists suggest, might have allowed the water that it swallowed to escape and so might have been a very early version of gills.

Submission + - 85% of the world's governments are corrupt (newatlas.com)

Submitted by schwit1
schwit1 writes: According to one think tank that studies corruption in government, 85% of the world lives under governments that are essentially corrupt.

“Corruption” is defined by Transparency International (TI) as “the abuse of entrusted power for private gain.” Each year since 1995, TI has published a Corruption Perceptions Index that scores the world’s nations out of 100 for their public sector honesty and the just-released 2016 report paints the same bleak picture we’ve been seeing now for two decades except it’s getting worse.

According to the data, despite the illusion of elected government in half the world’s countries, democracy is losing. Only two countries scored 90 out of 100 this year, and just 54 of the 176 countries (30%) assessed in the report scored better than 50. Fifty percent might have constituted a pass in a High School arithmetic test, but for an elected government to be so inept at carrying out the will of the electorate, it is a clear betrayal of the people. The average country score this year is a paltry 43, indicating endemic corruption in a country’s public sector is the norm.

Even more damning is that more countries declined than improved in this year’s results.

Not surprisingly, the countries at the bottom of the list are almost all Middle Eastern nations, all of whom are the source of most of the world’s terrorism and Islamic madness. The few others are those trying to become communist paradises, Venezuela and North Korea.

Submission + - Fifty years ago today: the Apollo 1 launchpad fire (nasaspaceflight.com)

Fifty years ago Friday, the first – but sadly not the last – fatal spaceflight accident struck NASA when a fire claimed the lives of Virgil “Gus” Grissom, Roger Chaffee, and Ed White during a training exercise at Launch Complex 34. The accident, a major setback for the struggling Apollo program, ushered in the first understanding of the “bad day” effects of schedule pressure for spaceflight and brought with it words and reminders that still echo today.

The article provides a very detailed and accurate look at the history and causes of the accident, as well as its consequences, which even today influence American space engineering.

Submission + - At-home brain-zapping treatment for depression may soon be mainstream (ieee.org)

Submitted by the_newsbeagle
the_newsbeagle writes: This isn't old-school brain zapping: It's not electroshock therapy, in which doctors flood a depressed patient's brain with some 900 milliamps of current to cause a seizure and something like a mood reset. This is tDCS (transcranial direct current stimulation), which would let psychiatrists send their depressed patients home with a brain-zapping headband that sends perhaps 2 milliamps of current through specific portions of their brains. A doctor's prescription might call for the patient to do a 20-minute stimulation session daily for a few weeks, then less frequent maintenance sessions.

While tDCS is being investigated as a treatment for all sorts of neuropsychiatric disorders, many researchers and doctors think depression may be the killer app. A South Korean company called Ybrain thinks its consumer-friendly headband for depression will be the product that makes this treatment mainstream — first in Korea, then in Europe, then in the United States and around the world.

Submission + - Malvertising Campaign Infects Your Router Instead of Your Browser (bleepingcomputer.com)

Submitted by Anonymous Coward
An anonymous reader writes: Malicious ads are serving exploit code to infect routers, instead of browsers, in order to insert ads in every site users are visiting. Unlike previous malvertising campaigns that targeted users of old Flash or Internet Explorer versions, this campaign focused on Chrome users, on both desktop and mobile devices.

The malicious ads included in this malvertising campaign contain exploit code for 166 router models, which allow attackers to take over the device and insert ads on websites that didn't feature ads, or replace original ads with the attackers' own. Researchers haven't yet managed to determine an exact list of affected router models, but some of the brands targeted by the attackers include Linksys, Netgear, D-Link, Comtrend, Pirelli, and Zyxel.

Because the attack is carried out via the user's browser, using strong router passwords or disabling the administration interface is not enough. The only way users can stay safe is if they update their router's firmware to the most recent versions, which most likely includes protection against the vulnerabilities used by this campaign.

Submission + - First Offshore Wind Farm In US Waters Delivers Power To Rhode Island (arstechnica.com)

Submitted by Anonymous Coward
An anonymous reader writes: On Monday, energy company Deepwater Wind announced that its wind farm three miles off the coast of Block Island, Rhode Island, has the all-clear to sell electricity to the regional power grid. The Block Island Wind Farm is the first offshore wind energy plant in the U.S., and it's expected to produce 30 MW of electricity at full capacity. Deepwater Wind is slowly ramping up energy output and still must provide additional paperwork to the Rhode Island Coastal Resources Management Council, but the executive director of that organization, Grover Fugate, told the Providence Journal, “we don't anticipate any major issues” to getting the wind farm fully online. The one hitch in the Deepwater's plan is that one of the five turbines was recently damaged when a drill bit was left in a critical part of turbine. According to the Providence Journal, "the bit had caused damage to an unspecified number of the 128 magnet modules that line the circular generator and are critical to producing energy." Although the magnet modules can apparently be replaced easily, Deepwater needs to have the components shipped from France, where General Electric, the manufacturer of the wind turbines, makes them. For now, four turbines capable of churning out 6 MW of power each are operational. The Providence Journal notes that National Grid will pay Deepwater Wind 24.4 cents per kilowatt hour of power, with the price escalating over time to 47.9 cents per kilowatt hour. Because the residents of Block Island have some of the most expensive electricity rates in the nation, they will actually see energy savings, despite the price. Mainland Rhode Islanders, on the other hand, will pay an extra $1.07 per month on average.

Submission + - Google Publishes Eight National Security Letters (techcrunch.com)

Submitted by Anonymous Coward
An anonymous reader writes: Google dropped a single National Security Letter into its most recent transparency report without much fanfare, but today the company published eight more NSLs in an attempt to shed more light on government surveillance of Google users. The eight letters published today were sent to Google from FBI offices across the country. Cumulatively, the NSLs seek broad access to content for around 20 user accounts. The names of the targets are redacted, but most of the letters seek access to Gmail accounts. The NSLs were sent to Google over a five-year period, from 2010 to 2015, with the majority coming from the Charlotte, North Carolina field office of the FBI. Others came from Florida, Arizona, New York, and California. “In our continued effort to increase transparency around government demands for user data, today we begin to make available to the public the National Security Letters (NSLs) we have received where, either through litigation or legislation, we have been freed of nondisclosure obligations,” Richard Salgado, Google’s director of law enforcement and information security, wrote in a blog post. Google has fought to make the letters public in part because the FBI can issue them without prior judicial oversight.

Submission + - Sysadmin Gets Two Years in Prison for Sabotaging ISP (bleepingcomputer.com)

Submitted by Anonymous Coward
An anonymous reader writes: Dariusz J. Prugar, 32, of Syracuse, New York, will have to spend 2 years in prison for hacking his former employee, Pa Online, an internet service provider (ISP) formerly located in Enola, Pennsylvania. According to authorities, Prugar had used his old credentials to log into the ISP's network and "take back" some of the scripts and software he wrote while as an employee there, after being fired in June 2010.

Seeking to hide his tracks, Prugar used an automated script that deleted various logs. As a side effect of removing some of these files, the ISP's systems crashed, affecting over 500 businesses and over 5,000 residential customers. When the former ISP couldn't fix the issue, they asked Prugar to help. During negotiations, instead of requesting money as payment, Prugar insisted that he'd be paid using the rights to the software and scripts he wrote while at the company, software which was now malfunctioning, a week after he left. This tipped off the company, who detected foul play, contacted the FBI and rebuilt its entire network. The ISP shut down operations in 2015.

Submission + - Stephen Hawking: Automation and AI Is Going To Decimate Middle Class Jobs (businessinsider.com)

Submitted by Anonymous Coward
An anonymous reader writes: In a column in The Guardian, the world-famous physicist wrote that "the automation of factories has already decimated jobs in traditional manufacturing, and the rise of artificial intelligence is likely to extend this job destruction deep into the middle classes, with only the most caring, creative or supervisory roles remaining." He adds his voice to a growing chorus of experts concerned about the effects that technology will have on workforce in the coming years and decades. The fear is that while artificial intelligence will bring radical increases in efficiency in industry, for ordinary people this will translate into unemployment and uncertainty, as their human jobs are replaced by machines. Automation will, "in turn will accelerate the already widening economic inequality around the world," Hawking wrote. "The internet and the platforms that it makes possible allow very small groups of individuals to make enormous profits while employing very few people. This is inevitable, it is progress, but it is also socially destructive." He frames this economic anxiety as a reason for the rise in right-wing, populist politics in the West: "We are living in a world of widening, not diminishing, financial inequality, in which many people can see not just their standard of living, but their ability to earn a living at all, disappearing. It is no wonder then that they are searching for a new deal, which Trump and Brexit might have appeared to represent." Combined with other issues — overpopulation, climate change, disease — we are, Hawking warns ominously, at "the most dangerous moment in the development of humanity." Humanity must come together if we are to overcome these challenges, he says.

Submission + - Neuroscientists Say Simple Mathematical Logic Drives Complex Brain Computation (sci-news.com)

Submitted by hackingbear
hackingbear writes: According to Dr. Joe Tsien, a neuroscientist at the Medical College of Georgia at Augusta University, the brain’s basic computational algorithm is organized by power-of-two-based logic. He and his colleagues from US and China have documented the algorithm at work in seven different brain regions involved with those basics like food and fear in mice and hamsters. “Intelligence is really about dealing with uncertainty and infinite possibilities,” he said, “It appears to be enabled when a group of similar neurons form a variety of cliques to handle each basic like recognizing food, shelter, friends and foes. Groups of cliques then cluster into functional connectivity motifs (FCMs) to handle every possibility in each of these basics. The more complex the thought, the more cliques join in.”
