Toshiba's Fast-Charging Battery Could Triple the Range of Electric Vehicles

Sat, 10/14/2017 - 17:34
Big Hairy Ian quotes New Atlas: A key focus of electric vehicle (EV) makers is maximizing the range users can get from each charge, and for that reason new battery technologies are poised to play a huge part in driving their adoption. Toshiba has developed a new fast-charging battery it claims could allow EVs to travel three times as far as they do now, and then be fully recharged again in a matter of minutes. Toshiba's SCiB (Super Charge ion Battery) has been around in various forms since 2007, with its chief claim to fame an ability to charge to 90 percent of capacity in just five minutes. It also boasts a life-span of 10 years and high levels of safety, and has found its way into a number of notable EVs, including Mitsubishi's i MiEV and Honda's Fit EV. The current SCiB uses lithium titanium oxide as its anode, but Toshiba says it has now come up with a better way of doing things. The next-generation SCiB uses a new material for the anode called titanium niobium oxide, which Toshiba was able to arrange into a crystal structure that can store lithium ions more efficiently. So much so, that the energy density has been doubled. Toshiba calls the battery "a game changing advance that will make a significant difference to the range and performance of EV," and hopes to put it "into practical application" in 2019.

Tesla Just Fired Hundreds Of Workers

Sat, 10/14/2017 - 16:34
An anonymous reader quotes the Bay Area Newsgroup: Tesla fired hundreds of workers this week, including engineers, managers and factory workers, even as the company struggles to expand its manufacturing and product line... The company said this week's dismissals were the result of a company-wide annual review, and insisted they were not layoffs. Some workers received promotions and bonuses, and the company expects to hire for the "vast majority" of new vacancies, a spokesman said. "As with any company, especially one of over 33,000 employees, performance reviews also occasionally result in employee departures," a spokesman said. "Tesla is continuing to grow and hire new employees around the world." "Tesla has a hearing before the National Labor Relations Board in November for charges that company supervisors and security guards harassed workers distributing union literature," reports the Bay Area Newsgroup, adding that "Openly pro-union workers were among those fired this week. Some believe they were targeted." Tesla denies this, and says that they've generally boosted morale this week -- by rewarding higher-performing employees.

Russia Reportedly Used Pokemon Go In an Effort To Inflame Racial Tensions

Sat, 10/14/2017 - 15:00
An anonymous reader quotes a report from The Verge: Russia's far-ranging campaign to promote dissension in the United States reportedly included an effort to weaponize Pokemon Go. CNN reported that in July 2016, a Tumblr page linked to Russia's now-notorious Internet Research Agency promoted a contest encouraging people sympathetic to the Black Lives Matter movement to play the game near famous sites of police brutality. Players were told to change their characters' names to the victims of those incidents -- an apparent effort to inflame racial tensions. The Tumblr page was linked to Do Not Shoot Us, a multi-platform campaign designed to mimic aspects of Black Lives Matter. (As CNN notes, the name plays on "hands up, don't shoot," one of the movement's slogans.) Do Not Shoot Us included a website, donotshoot.us, along with related pages on Facebook, Instagram, Twitter, and YouTube. The Facebook page was one of 470 pages that were removed after the company determined that it was linked to Russian groups attempting to interfere in US politics.

Google Slashes Prices of Its USB-C Headphone Dongle Following Minor Outrage

Sat, 10/14/2017 - 12:00
At its hardware event last week, Google unveiled its two new flagship smartphones: the Pixel 2 and Pixel 2 XL. While these devices feature high-end specifications and the latest version of Android, they both lack headphone jacks, upsetting many consumers who still rely heavily on wired headphones. To add insult to injury, Google announced a USB-C adapter for a whopping price of $20 -- that's $11 more than Apple's Lightning to 3.5mm adapter. This resulted in some minor outrage and caused Google to rethink its decision(s). As reported by 9to5Google, Google decided to slash the price of the dongle by over 50%. It is now priced at a more reasonable $9.

Microwave Tech Could Produce 40TB Hard Drives In the Near Future

Sat, 10/14/2017 - 09:00
Western Digital has announced a potential game changer that promises to expand the limits of traditional HDDs to up to 40TBs using a microwave-based write head, and the company says it will be able to the public in 2019. Gizmodo reports: Western Digital's new approach, microwave-assisted magnetic recording (MAMR), can utilize the company's existing production chain to cram a lot more storage onto a 3.5-inch disk. In a technical overview, Western Digital says it has managed to overcome the biggest issue with traditional HDD drive storage -- the size of the write head. These days, an average hard drive maxes out in the 10-14TB range. But by integrating a new write head, "a spin torque oscillator," microwaves can create the energy levels necessary for copying data within a lower magnetic field than was ever previously possible. There's a more thorough white paper for those who want to dive in. According to Western Digital, MAMR has "the capability to extend areal density gains up to 4 Terabits per square inch." By the year 2025, it hopes to be packing 40TBs into the same size drive it offers today.

Magic Mushrooms 'Reboot' Brain In Depressed People, Study Suggests

Sat, 10/14/2017 - 05:30
An anonymous reader quotes a report from The Guardian: Magic mushrooms may effectively "reset" the activity of key brain circuits known to play a role in depression, the latest study to highlight the therapeutic benefits of psychedelics suggests. Psychedelics have shown promising results in the treatment of depression and addictions in a number of clinical trials over the last decade. Imperial College London researchers used psilocybin -- the psychoactive compound that occurs naturally in magic mushrooms -- to treat a small number of patients with depression, monitoring their brain function, before and after. Images of patients' brains revealed changes in brain activity that were associated with marked and lasting reductions in depressive symptoms and participants in the trial reported benefits lasting up to five weeks after treatment. Dr Robin Carhart-Harris, head of psychedelic research at Imperial, who led the study, said: "We have shown for the first time clear changes in brain activity in depressed people treated with psilocybin after failing to respond to conventional treatments. Several of our patients described feeling 'reset' after the treatment and often used computer analogies. For example, one said he felt like his brain had been 'defragged' like a computer hard drive, and another said he felt 'rebooted.' Psilocybin may be giving these individuals the temporary 'kick start' they need to break out of their depressive states and these imaging results do tentatively support a 'reset' analogy. Similar brain effects to these have been seen with electroconvulsive therapy." The study has been published in Scientific Reports.

Latest iOS Update Shows Apple Can Use Software To Break Phones Repaired By Independent Shops

Sat, 10/14/2017 - 04:05
The latest version of iOS fixes several bugs, including one that caused a loss of touch functionality on a small subset of phones that had been repaired with certain third-party screens and had been updated to iOS 11. "Addresses an issue where touch input was unresponsive on some iPhone 6S displays because they were not serviced with genuine Apple parts," the update reads. "Note: Non-genuine replacement displays may have compromised visual quality and may fail to work correctly. Apple-certified screen repairs are performed by trusted experts who use genuine Apple parts. See support.apple.com for more information." Jason Koebler writes via Motherboard: "This is a reminder that Apple seems to have the ability to push out software updates that can kill hardware and replacement parts it did not sell iPhone customers itself, and that it can fix those same issues remotely." From the report: So let's consider what actually happened here. iPhones that had been repaired and were in perfect working order suddenly stopped working after Apple updated its software. Apple was then able to fix the problem remotely. Apple then put out a warning blaming the parts that were used to do the repair. Poof -- phone doesn't work. Poof -- phone works again. In this case, not all phones that used third party parts were affected, and there's no reason to think that, in this case, Apple broke these particular phones on purpose. But there is currently nothing stopping the company from using software to control unauthorized repair: For instance, you cannot replace the home button on an iPhone 7 without Apple's proprietary "Horizon Machine" that re-syncs a new home button with the repaired phone. This software update is concerning because it not only undermines the reputation of independent repair among Apple customers, but because it shows that phones that don't use "genuine" parts could potentially one day be bricked remotely.

Over 500 Million PCs Are Secretly Mining Cryptocurrency, Researchers Reveal

Sat, 10/14/2017 - 03:25
Ad blocking firm AdGuard has found that over 500 million people are inadvertently mining cryptocurrencies through their computers after visiting websites that are running background mining software. The company found 220 popular websites with an aggregated audience of half a billion people use so-called crypto-mining scripts when a user opens their main page. Newsweek reports: The mining tool works by hijacking a computer's central processing unit (CPU), commonly referred to as "the brains" of a computer. Using part of a computer's CPU to mine bitcoin effects the machine's overall performance and will slow it down by using up processing power. The researchers found that bitcoin browser mining is mostly found on websites "with a shady reputation" due to the trouble such sites have with earning revenue through advertising. However, in the future it could become a legitimate and ethical way of making money if the website requests the permission of the visitor first. "220 sites may not seem like a lot," the researchers wrote in a blogpost detailing their discovery. "But CoinHive was launched less than one month ago on September 14. The growth has been extremely rapid: from nearly zero to 2.2 percent of Alexa's top 100,000 websites. "This analysis well illustrates the whole web, so it's safe to say that one of every forty websites currently mines cryptocurrency (namely Monero) in the browsers their users employ."

Apple To Ditch Touch ID Altogether For All of Next Year's iPhones

Sat, 10/14/2017 - 02:05
Earlier this week, a report said that Apple is planning to equip next year's iPad Pro with the hardware necessary for Face ID. Now, according to KGI Securities analyst Ming-Chi Kuo, it appears the company is taking that one step further with its 2018 iPhones. All of the iPhones Apple plans to produce next year will reportedly abandon the Touch ID fingerprint sensor in favor of facial recognition. Mac Rumors reports: According to Kuo, Apple will embrace Face ID as its authentication method for a competitive advantage over Android smartphones. Kuo has previously said that it could take years for Android smartphone manufacturers to produce technology that can match the TrueDepth camera and the Face ID feature coming in the iPhone X. Face ID, says Kuo, will continue to be a major selling point of the new iPhone models in 2018, with Apple planning to capitalize on its lead in 3D sensing design and production. Kuo's prediction suggests that all upcoming 2018 iPhones will feature a full-screen design with minimal bezels like the iPhone X, meaning no additional models with the iPhone 8/iPhone 8 Plus design would be produced. That would spell the end of the line for Touch ID in the iPhone, which has been available as a biometric authentication option since 2013.

IRS Suspends $7 Million Contract With Equifax After Malware Discovered

Sat, 10/14/2017 - 01:20
After malware was discovered on Equifax's website again, the IRS decided late Thursday that it would temporarily suspend the agency's $7.1 million data security contract with the company. CBS News reports: In September, Equifax revealed that it had exposed 143 million consumer files -- containing names, addresses, Social Security numbers and even bank account information -- to hackers in an unprecedented security lapse. The number of consumer potentially affect by the data breach was later raised to 145.5 million. The company's former CEO blamed a single careless employee for the entire snafu. But even as he was getting grilled in Congress earlier this month, the IRS was awarding the company with a no-bid contract to provide "fraud prevention and taxpayer identification services." "Following new information available today, the IRS temporarily suspended its short-term contract with Equifax for identity proofing services," the agency said in a statement. "During this suspension, the IRS will continue its review of Equifax systems and security." The agency does not believe that any data the IRS has shared with Equifax to date has been compromised, but the suspension was taken as "a precautionary step."

Dutch Privacy Regulator Says Windows 10 Breaks the Law

Sat, 10/14/2017 - 00:40
An anonymous reader quotes a report from Ars Technica: The lack of clear information about what Microsoft does with the data that Windows 10 collects prevents consumers from giving their informed consent, says the Dutch Data Protection Authority (DPA). As such, the regulator says that the operating system is breaking the law. To comply with the law, the DPA says that Microsoft needs to get valid user consent: this means the company must be clearer about what data is collected and how that data is processed. The regulator also complains that the Windows 10 Creators Update doesn't always respect previously chosen settings about data collection. In the Creators Update, Microsoft introduced new, clearer wording about the data collection -- though this language still wasn't explicit about what was collected and why -- and it forced everyone to re-assert their privacy choices through a new settings page. In some situations, though, that page defaulted to the standard Windows options rather than defaulting to the settings previously chosen. In the Creators Update, Microsoft also explicitly enumerated all the data collected in Windows 10's "Basic" telemetry setting. However, the company has not done so for the "Full" option, and the Full option remains the default. The DPA's complaint doesn't call for Microsoft to offer a complete opt out of the telemetry and data collection, instead focusing on ensuring that Windows 10 users know what the operating system and Microsoft are doing with their data. The regulator says that Microsoft wants to "end all violations," but if the software company fails to do so, it faces sanctions.

Woz Wants To Retrain You For a Career in Tech

Sat, 10/14/2017 - 00:00
Steve Wozniak wants you to work in tech, and he's going to help you do it. From a report: The Apple co-founder is launching Woz U, a digital institute aimed at helping folks not only figure out what type of tech job they might be best at, but train for it. "People often are afraid to choose a technology-based career because they think they can't do it. I know they can, and I want to show them how," Wozniak said in a statement Friday. Woz U starts off as online programs, but there are plans to build campuses in 30 cities around the world. Those cities will be announced within the next 60 days, Shelly Murphy, corporate relations for Woz U told CNET. In a press statement, Wozniak said Woz U will start as an online learning platform focused on both students and companies that will eventually hire those students. Woz U is based out of Arizona, and hopes to launch physical locations for learning in more than 30 cities across the globe.

Google is Essentially Building an Anti-Amazon Alliance, and Target is the Latest To Join

Fri, 10/13/2017 - 23:20
Google and the country's biggest brick-and-mortar retailers have one main problem in common: Amazon. Now both sides are acting like they are serious about working together to do something about it. From a report: On Thursday, Target and Google announced that they are expanding what was a years-old delivery partnership from a small experiment in a handful of cities to the entire continental U.S. The expansion will allow Target to become a retail partner in Google's voice-shopping initiative, which lets owners of the Google Home "smart" speaker order items through voice commands like owners of the Echo can do from Amazon. The announcement comes seven weeks after Walmart inked a similar deal with Google to offer hundreds of thousands of products through the service. Other big-box retailers like Home Depot are also on board. Voice commerce was the core of these recent announcements, and it may someday become popular for types of shopping like reordering household staples. But that's not what is most interesting here to me. Instead, it's the promise that Target is also beginning to work with Google "to create innovative digital experiences using ... other cutting-edge technologies to elevate Target's strength in style areas such as home, apparel and beauty."

Why China is Winning the Clean Energy Race

Fri, 10/13/2017 - 22:40
An anonymous reader shares a report: U.S. politicians have been warning for years that America couldn't let China win the clean energy race. That's exactly what has happened, with the trends most stark in electric cars, solar and nuclear energy. Why it matters: Building for the last decade, these trends have accelerated in the last couple of years. Politicians and business leaders said America's dominance in this space would bring jobs to the U.S. and security to our clean-energy resources, and now both of those goals are at risk. Why China is doing this: It needs to literally energize its 1.4 billion people, both how they travel and how they power their homes. Its leadership feels compelled to do it in a cleaner way than the U.S. did. Air pollution is at dangerously high levels across many of China's cities. People are seeing and feeling health repercussions of China's dependence on fossil fuel-fired cars and power plants in an acute way. Traditional air pollution, not climate change, is a big driver.

IT Admin Trashes Railroad Company's Network Before He Leaves

Fri, 10/13/2017 - 22:00
Catalin Cimpanu, writing for BleepingComputer: A federal jury in Minneapolis, Minnesota found a local man guilty of intentionally damaging his former employer's network before leaving the company. The man's name is Christopher Victor Grupe, 46, and from September 2013 until December 2015 he worked as an IT professional for the Canadian Pacific Railway (CPR), a transcontinental railroad based in Alberta, Canada. Things went sideways in December 2015 when CPR suspended Grupe for 12 days for yelling and using inadequate language with his boss. When the man returned to work following his suspension on December 15, management told Grupe they were going to fire him for insubordination. According to court documents obtained by Bleeping Computer, Grupe asked management to resign, effective immediately. He promised to come back the following days and return company property such as his laptop, remote access device, and access badges. He did return the items, as promised, but not before taking the laptop for a last spin inside CPR's network. Court documents show Grupe accessed the company's switches and removed admin accounts, changed passwords for other admin accounts, and deleted log files. When done, Grupe wiped his laptop and returned it to CPR's Minnesota office on December 17, two days after he resigned.

SWIFT Says Hackers Still Targeting Bank Messaging System

Fri, 10/13/2017 - 21:20
Hackers continue to target the SWIFT bank messaging system, though security controls instituted after last year's $81 million heist at Bangladesh's central bank have helped thwart many of those attempts, a senior SWIFT official told Reuters. From the report: "Attempts continue," said Stephen Gilderdale, head of SWIFT's Customer Security Programme, in a phone interview. "That is what we expected. We didn't expect the adversaries to suddenly disappear." SWIFT spokeswoman Natasha de Teran told Reuters that the attackers had attempted to hack into computers that banks use to access the organization's proprietary network, then create fraudulent messages to send over the SWIFT system. "We have no indication that our network and core messaging services have been compromised," she said. The disclosure underscores that banks remain at risk of cyber attacks targeting computers used to access SWIFT almost two years after the February 2016 theft from a Bangladesh Bank account at the Federal Reserve Bank of New York.

Qualcomm Seeks China iPhone Ban, Escalating Apple Legal Fight

Fri, 10/13/2017 - 20:40
Qualcomm filed lawsuits in China seeking to ban the sale and manufacture of iPhones in the country, the chipmaker's biggest shot at Apple so far in a sprawling and bitter legal fight. From a report: The San Diego-based company aims to inflict pain on Apple in the world's largest market for smartphones and cut off production in a country where most iPhones are made. The product provides almost two-thirds of Apple's revenue. Qualcomm filed the suits in a Beijing intellectual property court claiming patent infringement and seeking injunctive relief, according to Christine Trimble, a company spokeswoman. "Apple employs technologies invented by Qualcomm without paying for them," Trimble said. An Apple spokesman didn't immediately respond to a request for comment on Friday. Qualcomm's suits are based on three non-standard essential patents, it said. They cover power management and a touch-screen technology called Force Touch that Apple uses in current iPhones, Qualcomm said. The inventions "are a few examples of the many Qualcomm technologies that Apple uses to improve its devices and increase its profits," Trimble said. The company made the filings at the Beijing court on Sept. 29. The court has not yet made them public.

This Is the Week Wall Street Went Nuts Over Cryptocurrencies

Fri, 10/13/2017 - 20:00
Wall Street banks that weren't already on the bitcoin bandwagon appear to be piling on, or least eyeing seats, after the cryptocurrency surged to all-time highs this week on the way to $6,000. From a report: Analysts are working to keep up with demand from clients for information. UBS and Citigroup published extensive explainers on blockchain technology, while senior executives at JPMorgan Chase warmed to the cryptocurrency during the bank's third-quarter earnings call. The digital currency has risen more than fivefold after trading at less than $1,000 as recently as December, breaking the $5,000 mark this week and already targeting the next thousand-dollar level. Throughout its rise, the cryptocurrency shrugged off tighter regulations, feuding factions and warnings from the likes of JPMorgan's Jamie Dimon of fraud and an eventual price collapse.
