Australian Scientists Figure Out How Zinc-Air Batteries Can Replace Lithium-Ion Batteries

1 hour 17 min ago
Researchers at the University of Sydney has figured out how to solve one of the biggest problems standing in the way for zinc-air batteries to replace lithium-ion batteries. The reason zinc batteries are so sought after is because they're powered by zinc metal -- the 24th most abundant element in Earth's crust. Not only are they cheaper to produce than lithium-ion batteries, they can theoretically store five times more energy, are much safer and environmentally friendly. The problem with zinc batteries stems around them being difficult to charge because of the lack of electrocatalysts needed to reduce and generate oxygen during the discharging and charging of a battery. labnet shares a report from Gizmodo: "Up until now, rechargeable zinc-air batteries have been made with expensive precious metal catalysts, such as platinum and iridium oxide. In contrast, our method produces a family of new high-performance and low-cost catalysts." These new catalysts are produced through the simultaneous control of the composition, size and crystallinity of metal oxides of earth-abundant elements like iron, cobalt and nickel. They can then be applied to build rechargeable zinc-air batteries. Researcher Dr Li Wei, also from the University's Faculty of Engineering and Information Technologies, said trials of zinc-air batteries developed with the new catalysts had demonstrated "excellent rechargeability" -- including less than a 10 percent battery efficacy drop over 60 discharging/charging cycles of 120 hours. The research was published in the journal Advanced Materials.

Cloudflare Stops Supporting Neo-Nazi Site The Daily Stormer

1 hour 54 min ago
Timothy B. Lee reports via Ars Technica: All week, the infamous hate site Daily Stormer has been battling to stay online in the face of a concerted social media campaign to shut it down. The site lost its "dailystormer.com" domain on Monday after first GoDaddy and then Google Domains blacklisted it from their domain registration services. The site re-appeared online on Wednesday morning at a new domain name, dailystormer.ru. But within hours, the site had gone offline again after it was dropped by Cloudflare, an intermediary that defends customers against denial-of-service attacks. Daily Stormer's Andrew Anglin reported Cloudflare's decision to drop the site in a post on the social media site Gab. His post was first spotted by journalist Matthew Sheffield.

YouTube Has An Illegal TV Streaming Problem

2 hours 37 min ago
An anonymous reader quotes a report from Mashable: Most people turn to Netflix to binge watch full seasons of a single TV show, but there could be a much cheaper way: YouTube. You might be surprised to learn that you can watch full episodes of popular TV shows on YouTube for free, thanks to a large number of rogue accounts that are hosting illegal live streams of shows. Perhaps the most shocking thing about these free (and very illegal) TV live streams might even make their way into your suggested video queue, if you watch enough "random shit" and Bobby Hill quote compilations on the site, as Mashable business editor Jason Abbruzzese recently experienced. He first noticed the surprisingly high number of illegal TV streaming accounts on his YouTube homepage, which has tailored recommended videos based on his viewing habits. Personalized recommendations aren't exactly new -- but the number of illegal live streams broadcasting copyrighted material on a loop was a shocker. When we looked deeper into the livestreams, the number we found was mindblowing. Many of these accounts appear to exist solely to give watchers an endless loop of their favorite shows and only have a few other posts related to the live streamed content. "YouTube respects the rights of copyright holders and we've invested heavily in copyright and content management tools to give rights holders control of their content on YouTube," a YouTube spokesperson told Mashable in an email. "When copyright holders work with us to provide reference files for their content, we ensure all live broadcasts are scanned for third party content, and we either pause or terminate streams when we find matches to third party content."

Email Provider ProtonMail Says It Hacked Back, Then Walks Claim Back

3 hours 17 min ago
An anonymous reader shares a report: On Wednesday, encrypted email provider ProtonMail claimed it had hacked someone who was impersonating its service in phishing emails, and the company then swiftly deleted the tweet. Early Wednesday morning, the security researcher known as x0rz tweeted out a series of screenshots allegedly showing someone sending emails that directed targets to a fake ProtonMail login screen. "You have an overdue invoice," the message read. In response, ProtonMail said it had taken action. "We also hacked the phishing site so the link is down now," ProtonMail tweeted. Depending on the context and what exactly the retaliating organization did, hacking back can be illegal. Hacking could violate the Computer Fraud and Abuse Act, or perhaps even wiretapping legislation. A recently proposed bill would attempt to legalize the practice. ProtonMail swiftly deleted its tweet, but not before x0rz could grab and subsequently tweet a screenshot. x0rz then deleted his own tweet at the request of ProtonMail.

Shipping Company Maersk Says June Cyberattack Could Cost It Up To $300 Million

3 hours 54 min ago
An anonymous reader shares an article: Container shipping company A.P. Moller Maersk on Tuesday said it expects that computer issues triggered by the NotPetya cyberattack will cost the company as much as $300 million in lost revenue. "In the last week of the [second] quarter we were hit by a cyber-attack, which mainly impacted Maersk Line, APM Terminals and Damco," Maersk CEO Soren Skou said in a statement. "Business volumes were negatively affected for a couple of weeks in July and as a consequence, our Q3 results will be impacted. We expect that the cyber-attack will impact results negatively by USD 200-300m." Maersk Line was able to take bookings from existing customers two days after the attack, and things gradually got back to normal over the following week, the company said. It said it did not lose third-party data as a result of the attack.

After Losing Support, Trump's Business and Manufacturing Councils Are Shutting Down

4 hours 37 min ago
Over a dozen anonymous readers share a similar report: Two White House advisory councils that once included tech leaders like Elon Musk and Travis Kalanick have dissolved, after several members resigned over President Donald Trump's weak condemnation of white supremacists. A member of the Strategic and Policy Forum told CNBC that it wanted to make a "more significant impact" by disbanding the entire group: "It makes a central point that it's not going to go forward. It's done." Soon after, Trump took credit for shutting down both that group and a separate Manufacturing Council, "rather than putting pressure on the businesspeople." The councils' members came from a range of industries, including several major Silicon Valley companies. Besides Musk and Kalanick, executives from Intel, IBM, and Dell had joined. It's been controversial from the start -- Musk and Kalanick both left months ago -- but a major exodus started this week, after Trump issued a vague statement blaming "many sides" for violence at a white supremacist rally that left one woman dead. Intel CEO Brian Krzanich resigned on Monday, saying that politics had "sidelined the important mission of rebuilding America's manufacturing base." Axios has more details.

The Docx Games: Three Days At the Microsoft Office World Championship

5 hours 17 min ago
An anonymous reader shares a report: On a Sunday night two weeks back, in the Rose Court Garden of the Disneyland Hotel in Anaheim, California, 150 antsy competitors between the ages of 13 and 22 milled around eating miniature whoopie pies by the light of the Moon, sizing up their global rivals in the efficient use of Excel, PowerPoint, and Word. It was as if the Olympics opening ceremony was replaced by a networking event: teens were decked out in national T-shirts, while others handed out business cards specially made for the event. At one table off by the bar, two chaperones nudged their folding chairs closer together and taught each other how to say hello ("Yassas," "Ciao") in their respective mother tongues. In the distance, through the palms, the tiki torches of Trader Sam's, the hotel's poolside lounge, were flickering into the black sky. This marked the first night of the 16th Microsoft Office Specialist (MOS) World Championship, in which teens and young 20-somethings compete for the title of World Champion in their chosen professional application. It's an event put on annually by Certiport, a Utah-based subsidiary of standardized testing giant Pearson VUE. It's also a marketing stunt, pure and simple, devised to promote Certiport's line of Microsoft Office certifications. This allows the certified to confirm the line on their resume that claims "proficiency in MS Office" is backed up by some solid knowledge of deep formatting and presentation design.

Tiny Robots Crawl Through Mouse's Stomach To Release Antibiotics

5 hours 55 min ago
Tiny robotic drug deliveries could soon be treating diseases inside your body. For the first time, micromotors -- autonomous vehicles the width of a human hair -- have cured bacterial infections in the stomachs of mice, using bubbles to power the transport of antibiotics. From a report: "The movement itself improves the retention of antibiotics on the stomach lining where the bacteria are concentrated," says Joseph Wang at the University of California San Diego, who led the research with Liangfang Zhang. In mice with bacterial stomach infections, the team used the micromotors to administer a dose of antibiotics daily for five days. At the end of the treatment, they found their approach was more effective than regular doses of medicine. The tiny vehicles consist of a spherical magnesium core coated with several different layers that offer protection, treatment, and the ability to stick to stomach walls. After they are swallowed, the magnesium cores react with gastric acid to produce a stream of hydrogen bubbles that propel the motors around. This process briefly reduces acidity in the stomach. The antibiotic layer of the micromotor is sensitive to the surrounding acidity, and when this is lowered, the antibiotics are released.

Higher Minimum Wages Bring Automation and Job Losses, Study Suggests

7 hours 56 min ago
An anonymous reader shares a report via email: As of the start of the year, 19 U.S. states had raised minimum wages, dramatizing a long simmering debate: Do minimum wages kill jobs, and make the working class worse off in the end? Or do they simply make them a little richer, with little or no loss to overall employment? In a new paper, economists Grace Lordan of the London School of Economics and David Neumark of UC Irvine parse 35 years of census data and come down on the worse-off side: For lower-skill jobs like bookkeepers and assembly-line workers, they say, higher minimum wages encourage employers to automate -- according to their calculations, a $1 increase can cost tens of thousands of jobs nationally.

Apple Is Bringing a Billion Dollar Checkbook To Hollywood and Wants To Buy 10 TV Shows

9 hours 57 min ago
Apple is officially open for business in Hollywood. From a report: The company is telling content makers it wants to spend $1 billion on its own stuff over the next year. That's music to studios' ears, and a tune they have been expecting for some time -- especially after Apple hired two top Sony TV executives in June. We still don't know what Apple wants to do with that content: The Wall Street Journal says Apple wants to make up to 10 "Game of Thrones" -- or "House of Cards"-scale shows, but that's not enough to launch a full-scale subscription service.

WordPress Bans Fascist Website Linked To Charlottesville Killer

10 hours 57 min ago
tedlistens writes: WordPress has said that it does not censor websites like that of self-proclaimed fascist group Vanguard America. But last night, the group's site was taken offline for violating the company's terms of service. The about-face was likely prompted by Vanguard's participation in last weekend's Unite the Right rallies in Charlottesville, Virginia, during which James Alex Fields drove his car into a crowd, killing one person and injuring 19. Fields has claimed allegiance to Vanguard America; the group denies that Fields was a member. For WordPress to drop a site, even a fascist site, is a very big deal; the same is true of GoDaddy's and Google's decision to drop their registration of neo-Nazi site the Daily Stormer (another site that GoDaddy previously said would be permitted on free speech grounds). WordPress hasn't explained the shift in its approach to the website: the company's user agreement and terms of service have not changed since Charlottesville. That policy, like that of other tech platforms, has long stood by strict neutrality and freedom of expression. That may now be changing.

Energy Drinks May Trigger Future Substance Use, Says Study

13 hours 57 min ago
New research suggests persistent consumption of energy drinks may predispose young adults to substance use. "Investigators, led by Amelia M. Arria, PhD, School of Public Health, University of Maryland, College Park, found that college students who regularly drink highly caffeinated energy drinks were at increased risk for later use of alcohol, cocaine, or prescription stimulants," reports Medscape. From the report: The research included students enrolled in an ongoing longitudinal study that began in 2004 at a large public university. The analysis included 1099 participants (54% women; 72% non-Hispanic white) who completed at least one annual assessment in which patterns of energy drink consumption were assessed. In interviews, participants were asked which energy drinks they had consumed, and how often, in the past year. They were categorized into three patterns of use: Frequent (52 or more days); Occasional (12 - 51 days); Infrequent (1 - 11 days). The investigators found that sensation seeking, conduct problems, and behavioral dysregulation were all positively associated with a higher probability of energy drink consumption, with the nonuse group having the lowest and the persistent group the highest risk scores. The study was published in the journal Drug and Alcohol Dependence.

Scientists Finally Unlock the Recipe For Magic Mushrooms

Tue, 08/15/2017 - 11:30pm
An anonymous reader writes: Aside from being a schedule 1 drug, scientists haven't fully understood the chemistry behind how mushrooms produce the chemical psilocybin -- until now. A new study may finally lay the groundwork for a medical-grade psilocybin patients can take. Gizmodo reports: "Living things make molecules through a series of chemical reactions, similar to how car makers produce cars on assembly lines. Enzymes act as the workers/robots, speeding up the reactions by helping put the pieces together. Actually making psilocybin requires mapping the biological factory. A 1968 paper (obviously it was in 1968) offered a proposed order of events leading to a finished psilocybin molecule, by adding radioactive elements and watching what happened to them on the assembly line. The researchers thought that maybe tryptophan, the amino acid everyone wrongly says makes you sleepy, was the first piece, which then went through four successive steps to become the finished product. The new study shows that the 1968 paper got the order wrong, and introduces the responsible genes and enzymes, the workers that do the specific task to get the final product. This time around, mapping the factory required sequencing the genomes of two magic mushroom species, Psilocybe cubensis and Psilocybe cyanescens. Then, the researchers found exactly which genes produce the required enzymes and spliced them into E. coli bacteria. Using those enzymes, they were able to rebuild the factory and create their own psilocybin." The study has been published in the German journal Angewandte Chemie.

Intel Officially Reveals Post-8th Generation Core Architecture Code Name: Ice Lake, Built On 10nm+

Tue, 08/15/2017 - 10:05pm
Intel has confirmed the existence of a new processor family called Ice Lake that will be made on Intel's 10nm+ process. The company published basic information on the Ice Lake architecture on their codename decoder. AnandTech reports: This is an unexpected development as the company has yet to formally detail (let alone launch) the first 10nm Core architecture -- Cannon Lake -- and it's rare these days for Intel to talk more than a generation ahead in CPU architectures. Equally as interesting is the fact that Intel is calling Ice Lake the successor to their upcoming 8th generation Coffee Lake processors, which codename bingo aside, throws some confusion on where the 14nm Coffee Lake and 10nm Cannon Lake will eventually stand. As a refresher, the last few generations of Core have been Sandy Bridge, Ivy Bridge, Broadwell, Haswell, Skylake, with Kaby Lake being the latest and was recently released at the top of the year. Kaby Lake is Intel's third Core product produced using a 14nm lithography process, specifically the second-generation '14 PLUS' (or 14+) version of Intel's 14nm process. Working purely on lithographic nomenclature, Intel has three processes on 14nm: 14, 14+, and 14++. As shown to everyone at Intel's Technology Manufacturing Day a couple of months ago, these will be followed by a trio of 10nm processes: 10nm, 10nm+ (10+), and 10++. On the desktop, Core processors will go from 14 to 14+ to 14++, such that we move from Skylake to Kaby Lake to Coffee Lake. On the Laptop side, this goes from 14 to 14+ to 14++/10, such that we move from Skylake to Kaby Lake to Coffee Lake like the desktops, but also that at some time during the Coffee Lake generation, Cannon Lake will also be launched for laptops. The next node for both after this is 10+, which will be helmed by the Ice Lake architecture.
