Submission + - Scientists in China predict pentagonal graphene

TechkNighT_1337 writes: Chinese scientists made calculations and predict that a new 2D allotrope of carbon based in a pentagonal form resembling an common pavement in the streets of cairo can be synthesized, they call this new form penta-graphene from the announcement in the Chemistry World they say: "The team found that not only should a pentagon-containing version of graphene be fairly stable, it should also be stronger than conventional graphene and be able to withstand higher temperatures, up to 730C. It would also be a natural semiconductor, unlike conventional graphene, which is a highly efficient conductor and has to be chemically modified to turn it into a semiconductor."

Submission + - Peak Google: The Company's Time at the Top May Be Nearing Its End

HughPickens.com writes: Farhad Manjoo writes at the NYT that at first glance Google looks plenty healthy, but growth in Google’s primary business, search advertising, has flattened out at about 20 percent a year for the last few years and although Google has spent considerable resources inventing technologies for the future, it has failed to turn many of its innovations into new moneymakers. According to Manjoo as smartphones eclipse laptop and desktop computers to become the planet’s most important computing devices, the digital ad business is rapidly changing and Facebook, Google’s archrival for advertising dollars, has been quick to profit from the shift. Here’s why: The advertising business is split, roughly, into two. On one side are direct-response ads meant to induce an immediate purchase: Think classifieds, the Yellow Pages, catalogs or Google's own text-based ads running alongside its search results. But the bulk of the ad industry is devoted to something called brand ads, the ads you see on television and print magazines that work on your emotions in the belief that, in time, your dollars will follow. “Google doesn’t create immersive experiences that you get lost in,” says Ben Thompson. “Google creates transactional services. You go to Google to search, or for maps, or with something else in mind. And those are the types of ads they have. But brand advertising isn’t about that kind of destination. It’s about an experience.” According to Thompson the future of online advertising looks increasingly like the business of television and is likely to be dominated by services like Facebook, Snapchat or Pinterest that keep people engaged for long periods of time and whose ads are proving to be massively more effective and engaging than banner advertisements.

In less than five years, Facebook has also built an enviable ad-technology infrastructure, a huge sales team that aims to persuade marketers of the benefits of Facebook ads over TV ads, and new ways for brands to measure how well their ads are doing. These efforts have paid off quickly: In 2014 Facebook sold $11.5 billion in ads, up 65 percent over 2013. Google will still make a lot of money if it doesn’t dominate online ads the way it does now. But it will need to find other businesses to keep growing. This is why Google is spending on projects like a self-driving car, Google Glass, fiber-optic lines in American cities, space exploration, and other audacious innovations that have a slim chance of succeeding but might revolutionize the world if they do. But the far-out projects remind Thompson of Microsoft, which has also invested heavily in research and development, and has seen little return on its investments. “To me the Microsoft comparison can’t be more clear. This is the price of being so successful — what you’re seeing is that when a company becomes dominant, its dominance precludes it from dominating the next thing. It’s almost like a natural law of business.”

Submission + - Facebook Launches ThreatExchange To Let Companies Share Threat Info

An anonymous reader writes: Facebook today launched ThreatExchange, described as “an API-based clearinghouse for security threat information.” It’s really a social platform, which Facebook naturally excels at building, which allows companies to share with each other details about malware and phishing attacks. Pinterest, Tumblr, Twitter, and Yahoo participated in ThreatExchange and gave feedback as Facebook was developing it. New contributors Bitly and Dropbox have also recently joined, bringing the initial participant list to seven major tech companies.

Submission + - Russia seeking to ban Tor, VPNs and other anonymising tools (thestack.com) 1

An anonymous reader writes: Three separate Russian authorities have spoken out in favour of banning online anonymising tools since February 5th, with particular emphasis on Tor, which — despite its popularity with whistle-blowers such as Edward Snowden and with online activists — Russia's Safe Internet League describes as an 'Anonymous network used primarily to commit crimes'. The three authorities involved are the Committee on Information Policy, Information Technologies and Communications, powerful Russian media watchdog Roskomnadzor and the Safe Internet League, comprising the country's top three network providers, including state telecoms provider Rostelecom. Roskomnadzor's press secretary Vadim Roskomnadzora Ampelonsky describes the obstacles to identifying and blocking Tor and VPN traffic as 'difficult, but solvable'.

Submission + - Wasp virus turns ladybugs into zombie babysitters (sciencemag.org)

sciencehabit writes: The green-eyed wasp Dinocampus coccinellae turns ladybugs into zombie babysitters. Three weeks after a wasp lays its egg inside the hapless beetle, a wasp larva bursts from her belly and weaves itself a cocoon between her legs. The ladybug doesn’t die, but becomes paralyzed, involuntarily twitching her spotted red carapace to ward off predators until the adult wasp emerges a week later. How D. coccinellae enslaves its host at just the right time had been a mystery, but now researchers believe the insect has an accomplice: a newly identified virus that attacks the beetle’s brain. The findings raise questions about whether other parasites also use viruses as neurological weapons.

Submission + - The Dark Web Still Thrives After Silk Road

HughPickens.com writes: Russell Berman writes at The Atlantic that the government may have won its case against Silk Road's Ross Ulbricht, but the high-profile trial gave a lot of publicity to the dark web, and both the number of sites and the volume of people using them have increased since Silk Road was shuttered. “Just as on the rest of the internet, users on the dark net are very quick to move on to new things and move away from those products and websites that seem stale and old,” says Adam Benson. The cat-and-mouse game between users of the dark web and law enforcement appears to be shifting as well. Newer dark sites (two major ones are Agora and Evolution) are likely to protect their servers by basing them in countries "hostile to U.S. law enforcement," says Nicholas Weaver. "The markets will keep moving overseas, but law enforcement will keep going after the dealers," Weaver says, referring to the people who actually ship and deliver the drugs sold online.

Evolution Marketplace is a much different animal than Silk Road, according to Dan Palumbo. Evolution sells "weapons, stolen credit cards, and more nefarious items that were forbidden on both versions of Silk Road. Silk Road sold a lot of dangerous things, but operators drew the line at their version of ‘victimless crimes,’ i.e. no child pornography, weapons, or identity theft. Now, four of the top five DarkNet Marketplaces sell weapons while three of the top five sell stolen financial data." This is a darker DarkNet and it speaks to the challenge facing law enforcement as they knock one set of bad actors offline, another comes along with bigger and bolder intentions.

Submission + - Microsoft trademarks Windows 365. Gives hint to renting (neowin.net)

Billly Gates writes: There was confusion during the Microsoft consumer preview of Windows 10 last month. Microsoft mentioned it was a free upgrade for one year for both Windows 7 and Windows 8.1 users. What did the meaning of "free for one year" mean? It turns on the government paperwork for the trademark included references for operating systems in addition to other services like video on demand and extra software. Does this mean Microsoft plans to go the road of Adobe and allow only rentals to use your own computer?

Submission + - NASA confirms results for 'impossible' space drive that uses no rocket fuel (examiner.com) 1

MarkWhittington writes: Last August, NASA’s Eagleworks, an advanced space propulsion lab located at the Johnson Spaceflight Center south of Houston, created a great deal of excitement when it announced that it had tested a prototype of something called a Cannae Drive. Using microwaves, the device seemed to exert a minute but measurable degree of thrust when mounted on a pendulum in a vacuum chamber. NextBigFuture provided an update on the experiments on an engine that uses no fuel and seems to violate Newtonian physics.

In essence, the team at Eagleworks has been able to replicate the results of the original experiment, exerting a thrust in the area of 50 micro-Newtons. The team has been hampered by a lack of funding to fight through equipment failures. Nevertheless, they are working, very slowly, to scale up the thrust to 100 micro-Newtons. At that point, they intend to take the device to the Glenn Research Center for another replication effort.

Submission + - Why the nuclear industry targets renewables instead of gas (midwestenergynews.com) 3

mdsolar writes: Cheap natural gas has upended the nation’s energy landscape and made aging nuclear power plants increasingly uncompetitive.

Yet the nuclear industry, which generates almost a fifth of the nation’s energy, has declared war not on gas but on wind and solar, which represent about 4 and 0.2 percent of our energy mix, respectively.

Nuclear generators have successfully fought against renewable and energy efficiency standards on the state level, and lobbied against tax incentives for wind and solar on the federal level. They’re in the process of securing changes in regional capacity markets that would benefit nuclear and harm solar and wind.

And as states develop their Clean Power Plans to fulfill the federal mandate to reduce carbon emissions, nuclear is often pitted against renewables.

In deregulated states like Illinois, Ohio, Michigan and Pennsylvania, nuclear generators have found it increasingly difficult to sell their power at a profit on open markets, because of competition primarily from gas but also from wind.

Meanwhile, energy efficiency and distributed solar generation have reduced demand for electricity and are part of a fundamental shift which could significantly shrink the role of large, centralized power plants.

Submission + - Photosynthesizing Sea Slugs Steal Genes From Algae (io9.com)

An anonymous reader writes: For decades, scientists have puzzled over how a certain sea slug acquires the ability to photosynthesize after ingesting algae. An advanced imaging technique now confirms that the slugs are literally stealing genes from the algae. It's considered the first example of "horizontal gene transfer" in a multicellular organism.

Submission + - Site Launches to Track Warrant Canaries

Trailrunner7 writes: In the years since Edward Snowden began putting much of the NSA‘s business in the street, including its reliance on the secret FISA court and National security Letters, warrant canaries have emerged as a key method for ISPs, telecoms and other technology providers to let the public know whether they have received any secret orders. But keeping track of the various canaries scattered around the Web is difficult, so a group of legal and civil liberties organizations have come together to launch a new site to monitor the known warrant canaries.

The Canary Watch site is the work of the EFF, the Berkman Center for Internet and Society and NYU’s Technology Law and Policy Center and it works on a simple concept. The site maintains a list of all of the known warrant canaries and periodically checks each organization’s site to see whether the canary is still there and then lists any changes to the status.

Right now, Canary Watch lists 11 organizations, including Lookout, Pinterest, Reddit and Tumblr.

“Canarywatch lists the warrant canaries we know about, tracks changes or disappearances of those canaries, and allows users to submit canaries not listed on the site. For people with interest in a particular canary, the site will show any changes we know about,” Nadia Kayyali of the EFF said in a blog post.

Submission + - Sony sells off Sony Online Entertainment 1

donniebaseball23 writes: Sony Online Entertainment is to become Daybreak Game Company and turn its focus to multi-platform gaming. The company been acquired by Columbus Nova and is now an indie studio. "We will continue to focus on delivering exceptional games to players around the world, as well as bringing our portfolio to new platforms, fully embracing the multi-platform world in which we all live," said Daybreak president John Smedley. But why did Sony shed SOE? Wedbush analyst Michael Pachter believes an online gaming company "isn't a great fit, particularly as games are shifting increasingly to a free-to-play mobile model."

Submission + - Gravity-defying trees explained by Newton (sciencemag.org)

sciencehabit writes: How do towering trees like redwoods defeat the pull of gravity to bring water up to their leaves? Isaac Newton, the father of gravity himself, came up with an explanation that is not too far off from the current scientific wisdom, according to an article published online today in Nature Plants. The arboreal feat stumped scientists until more than 200 years after Newton penned his botanical musings in an unpublished notebook he used in the 1660s. Newton suggested that light knocks away water particles from fluid-filled pores of the plant and “by this meanes juices continually arise up from the roots of trees upward,” he wrote. This bears a resemblance to the modern-day explanation—continuous chains of fluid form in the pores of the plant that stretch from root to leaves, aided by surface tension and the liquid clinging to the pore walls. Evaporation of water at the leaves pulls the chain of fluid up to the treetop.
