Turkey has launched a domestic messaging app to rival Facebook's popular WhatsApp Messenger service, raising concerns among government critics that Ankara (capital of Turkey) could use the new platform to tighten surveillance and bolster an 18-month-old crackdown. From a report: The app, called PttMessenger after Turkey's Post and Telegraph General Directorate (PTT), was introduced in a limited roll-out to state institutions and some private companies this week. It is expected to be publicly available in six months. PttMessenger will provide a "system safer than WhatsApp," government spokesman Bekir Bozdag told a news conference. "Since no data is stored with the host, it will be impossible to access these data. A system safer than WhatsApp has been developed." Critics cast doubt on the suggestion PttMessenger data could not be retrieved, fearing it will give authorities greater ability to monitor dissent, pointing to the widespread crackdown that was launched after a failed military coup in July 2016.

More problems and controversy for Logan Paul, the YouTube star who caused a strong public backlash when he posted a video of a suicide victim in Japan. From a report: Google's video platform today announced that it would be pulling advertising temporarily from his video channel in response to a "recent pattern of behavior" from him. This is in addition to Paul's suspensions from YouTube's Preferred Ad program and its Originals series, both of which have been in place since January; and comes days after YouTube's CEO promised stronger enforcement of YouTube's policies using a mix of technology and 10,000 human curators.

An anonymous reader quotes a report from Ars Technica: The company's development of the Falcon 9 rocket, with nine engines, had given Musk confidence that SpaceX could scale up to 27 engines in flight, and he believed this was a better overall solution for the thrust needed to escape Earth's gravity. To explain why, the former computer scientist used a computer metaphor. "It's sort of like the way modern computer systems are set up," Musk said. "With Google or Amazon they have large numbers of small computers, such that if one of the computers goes down it doesn't really affect your use of Google or Amazon. That's different from the old model of the mainframe approach, when you have one big mainframe and if it goes down, the whole system goes down."

For computers, Musk said, using large numbers of small computers ends up being a more efficient, smarter, and faster approach than using a few larger, more powerful computers. So it was with rocket engines. "It's better to use a large number of small engines," Musk said. With the Falcon Heavy rocket, he added, up to half a dozen engines could fail and the rocket would still make it to orbit. The flight of the Falcon Heavy likely bodes well for SpaceX's next rocket, the much larger Big Falcon Rocket (or BFR), now being designed at the company's Hawthorne, California-based headquarters. This booster will use 31 engines, four more than the Falcon Heavy. But it will also use larger, more powerful engines. The proposed Raptor engine has 380,000 pounds of thrust at sea level, compared to 190,000 pounds of thrust for the Merlin 1-D engine.

Asparagus and other foods like potatoes, nuts, legumes and soy contain a compound known as asparagine, which researchers believe helps drive the spread of breast cancer to other organs. "When scientists reduced asparagine in animals with breast cancer, they found that the number of secondary tumors in other tissues fell dramatically," The Guardian reports. "The spread of malignant cells, often to the bones, lungs and brain, is the main cause of death among patients who are diagnosed with breast cancer." From the report: Asparagine is an amino acid that is made naturally in the body as a building block for proteins. But it is also found in the diet, and in high levels in certain meats, vegetables and dairy products. The international team of cancer specialists from Britain, the U.S., and Canada studied mice with an aggressive form of breast cancer. The mice develop secondary tumors in a matter of weeks and tend to die from the disease within months. Writing in the journal Nature, the researchers describe how they reduced the ability of breast cancer to spread in the animals by blocking asparagine with a drug called L-asparaginase. To a lesser extent, by putting the animals on a low-asparagine diet worked too. Inspired by the results, the scientists examined records from human cancers and found that breast tumors that churned out the most asparagine were most likely to spread, leading patients to die sooner. The same was seen in cancers of the head, neck and kidney.

ClockEndGooner writes: Researchers at the Technische Universitat Wein have created a simulation of a simple worm's neural network, and have been able to replicate its natural behavior to completely mimic the worm's natural reflexive behavior. According to the article, using a simple neural network of 300 neurons, the simulation of "the worm can find its way, eat bacteria and react to certain external stimuli. It can, for example, react to a touch on its body. A reflexive response is triggered and the worm squirms away. This behavior is determined by the worm's nerve cells and the strength of the connections between them. When this simple reflex network is recreated on a computer, the simulated worm reacts in exactly the same way to a virtual stimulation -- not because anybody programmed it to do so, but because this kind of behavior is hard-wired in its neural network." Using the same neural network without adding any additional nerve cells, Mathias Lechner, Radu Grosu, and Ramin Hasani were able to have the nematode simulation learn to balance a pole "just by tuning the strength of the synaptic connections. This basic idea (tuning the connections between nerve cells) is also the characteristic feature of any natural learning process."

An anonymous reader shares an excerpt from a report via Quartz: As we've turned our gaze away from the stars and toward our screens, our anxiety about humanity's ultimate fate has shifted along with it. No longer are we afraid of aliens taking our freedom: It's the technology we're building on our own turf we should be worried about. The advent of artificial intelligence is increasingly bringing about the kinds of disturbing scenarios the old alien blockbusters warned us about. In 2016, Microsoft's first attempt at a functioning AI bot, Tay, became a Hitler-loving mess an hour after it launched. Tesla CEO Elon Musk urged the United Nations to ban the use of AI in weapons before it becomes "the third revolution in warfare." And in China, AI surveillance cameras are being rolled out by the government to track 1.3 billion people at a level Big Brother could only dream of. As AI's presence in film and TV has evolved, space creatures blowing us up now seems almost quaint compared to the frightening uncertainties of an computer-centric world. Will Smith went from saving Earth from alien destruction to saving it from robot servants run amok. More recently, Ex Machina, Chappie, and Transcendence have all explored the complexities that arise when the lines between human and robot blur.

However, sentient machines aren't a new anxiety. It arguably all started with Ridley Scott's 1982 cult classic, Blade Runner. It's a stunning depiction of a sprawling, smog-choked future, filled with bounty hunters muttering "enhance" at grainy pictures on computer screens. ("Alexa, enlarge image.") The neo-noir epic popularized the concept of intelligent machines being virtually indistinguishable from humans and asked the audience where our humanity ends and theirs begin. Even alien sci-fi now acknowledges that we've got worse things to worry about than extra-terrestrials: ourselves.

Ever since the inception of the Like button, Facebook users have been asking for a "dislike" button. Today, Facebook is testing a "downvote" button with certain users in the comment section of posts within Facebook groups and on old Facebook memories content. The Daily Beast reports: The feature appears to give users the ability to downrank certain comments. This is the first time Facebook has tested anything similar to a "dislike" button and it could theoretically allow for content that's offensive or relevant to be pushed to the bottom of a comment feed. In 2016, citing Facebook executives, Bloomberg said a dislike button "had been rejected on the grounds that it would sow too much negativity" to the platform. It's unclear how widely the dislike button is being tested. Facebook regularly tests features with small subsets of users that never end up rolling out to the broader public. Most users currently are only able to either Like or Reply to comments in a thread. The downvote option could have radical implications on what types of discussions and comments flourish on the platform. While it could theoretically be used to de-rank inflammatory or problematic comments, it could also easily be used as a tool for abuse.

In a bid to attract businesses involved in blockchain and cryptocurrencies, Arizona lawmakers have proposed a bill that would allow the state's citizens to pay their taxes in bitcoin. "Arizona State Rep. Jeff Weninger, who introduced the bill, said it was a signal to everyone in the United States, and possibly throughout the world, that Arizona was going to be the place to be for blockchain and digital currency technology in the future," reports Investopedia. From the report: Weninger, a Republican, also cited the ease of making online payments through the cryptocurrency "while you're watching television," as another reason. But he did not divulge much detail about the implementation of such a system. That might be the reason why Weninger faces an uphill battle in getting the bill approved by the state legislature. Bitcoin's price volatility is already being cited as a possible roadblock to implementing such a measure by state legislators. Arizona state senator Steve Farley, a Democrat who's running for governor, said the bill puts the "volatility burden" of bitcoin's price on taxpayers who make payments in U.S. dollars. "It would mean that the money goes to the state and then the state has to take responsibility of how to exchange it," Farley said.

schwit1 shares a report from Ars Technica, highlighting the problems the Germany Navy is facing right now. It has no working submarines due to a chronic repair parts shortage, and its newest ships face problems so severe that the first of the class failed its sea trials and was returned to the shipbuilders in December. From the report: The Baden-Wurttemberg class frigates were ordered to replace the 1980s-era Bremen class ships, all but two of which have been retired already. At 149 meters (488 feet) long with a displacement of 7,200 metric tons (about 7,900 U.S. tons), the Baden-Wurttembergs are about the size of destroyers and are intended to reduce the size of the crew required to operate them. Like the Zumwalt, the frigates are intended to have improved land attack capabilities -- a mission capability largely missing from the Deutsche Marine's other post-unification ships. The new frigate was supposed to be a master of all trades -- carrying Marines to deploy to fight ashore, providing gunfire support, hunting enemy ships and submarines, and capable of being deployed on far-flung missions for up to two years away from a home port. As with the U.S. Navy's LCS ships, the German Navy planned to alternate crews -- sending a fresh crew to meet the ship on deployment to relieve the standing crew.

Instead, the Baden-Wurttemberg now bears the undesirable distinction of being the first ship the German Navy has ever refused to accept after delivery. In fact, the future of the whole class of German frigates is now in doubt because of the huge number of problems experienced with the first ship during sea trials. So the Baden-Wurttemberg won't be shooting its guns at anything for the foreseeable future (and neither will the Zumwalt for the moment, since the U.S. Navy cancelled orders for their $800,000-per-shot projectiles). System integration issues are a major chunk of the Baden-Wurrenberg's problems. About 90 percent of the ship's systems are so new that they've never been deployed on a warship in fact -- they've never been tested together as part of what the U.S. Navy would call "a system of systems." And all of that new hardware and software have not played well together -- particularly with the ship's command and control computer system, the Atlas Naval Combat System (ANCS). schwit1 adds: "Perhaps most inexcusable, the ship doesn't even float right. It has a permanent list to starboard."

An anonymous reader quotes a report from Engadget: Earlier this week, a Reuters report suggested that the Consumer Financial Protection Bureau (CFPB) had halted its investigation into last year's massive Equifax data breach. Reuters sources said that even basic steps expected in such a probe hadn't been taken and efforts had stalled since Mick Mulvaney took over as head of the CFPB late last year. Now, 31 Democratic senators and one Independent have written a letter to Mulvaney asking if that is indeed the case and if so, why.

In their letter, the senators expressed their concern over these reports and reiterated the duty the CFPB has to not only investigate the breach but to bring action against Equifax if deemed necessary. "Consumer reporting agencies and the data they collect play a central role in consumers' access to credit and the fair and competitive pricing of that credit," they wrote. "Therefore, the CFPB has a duty to supervise consumer reporting agencies, investigate how this breach has or will harm consumers and bring enforcement actions as necessary."

Alphabet is close to acquiring the iconic Chelsea Market in Midtown Manhattan for over $2 billion. The market totals 1.2 million square feet and sits across the street from the company's New York headquarters, a 2.9 million-square-foot building that it bought for $1.8 billion in 2010. Quartz reports: Google is already the Market's largest tenant, having steadily expanded its footprint to about 400,000 square feet. The tech giant hasn't revealed plans for the property, but according to The Real Deal, the company is expected to maintain the status quo. Alphabet's aggressive expansion in New York follows a growing trend of tech giants taking over cities. With their outsized share of the economy, tech companies are exerting increasing influence over urban infrastructure and development.

A new zoning ordinance that quietly went into effect this week has residents trying to figure out what comes next for Airbnb's presence in Detroit. Many hosts have received notices that the city has outlawed Airbnb for R1 and R2 zoning. Curbed Detroit reports: The new zoning ordinance apparently went through the Planning Commission and City Council in 2017, and went into effect this week. The text added to the amendment states: "Use of a dwelling to accommodate paid overnight guests is prohibited as a home occupation; notwithstanding this regulation, public accommodations, including bed and breakfast inns outside the R1 and R2 Districts, are permitted as provided in Sec. 61-12-46 of this Code." The vast majority of Airbnb units in Detroit are in R1 and R2 districts. These do not include places like lofts, apartments, or larger developments. Airbnb has issued a statement saying: "We're very disappointed by this turn of events. Airbnb has served as an economic engine for middle class Detroiters, many of whom rely on the supplemental income to stay in their homes. We hope that the city listens to our host community and permits home sharing in these residential zones."

An anonymous reader quotes a report from The Verge: Tesla reported record revenue for 2017, floated by customer deposits of the recently announced Semi truck and Roadster sports car. Despite its optimistic sales numbers, Model 3 production issues and cash flow problems haunt the company, but Tesla insists its on track to meet its production goals of 5,000 cars a week by mid-2018. Tesla reported $3.3 billion in revenue, which was expected, but also posted a $771 million quarterly loss -- its largest quarterly loss ever. The company reported a negative free cash flow of $276.7 million. And it reported a net loss of $2.24 billion in 2017, a significant increase over the $773 million net loss it reported in 2016.

Bitcoin has essentially become the poster child for cryptocurrencies, and that's a problem for cybercriminals dealing on the dark web. From a report: Researchers from Recorded Future, a threat intelligence company, looked through 150 of the dark web's top marketplaces and forums and found that bitcoin's boom is driving shady characters away from the cryptocurrency. The rise of bitcoin has brought cryptocurrency -- digital alternatives to government-issued money -- to the mainstream, enticing people who are looking to get rich quick. Last December, bitcoin hit its all-time high at nearly $20,000, but it has since slumped and as of Thursday is trading at a little over the $8,000 mark. But before it was a massive investment that millionaires bought, it was the dark web's currency of choice, thanks to its decentralized and anonymous structure.

In an effort to force websites to better protect their users, the Chrome web browser will label all sites not encrypted traffic as "Not secure" in the web address bar, Google announced Thursday. From a report: Encrypted traffic allows users to access data on a website without allowing potential eavesdroppers to see anything the users visit. HTTPS also prevents meddlers from changing information in transit. During normal web browsing, Google currently displays a "Not secure" warning in the next to a site's URL if it forgoes HTTPS encryption and a user enters data. Now the browser will label all sites without HTTPS encryption this way.
