schwit1 writes: The Rice lab of chemist James Tour developed anodes comprising porous carbon made from asphalt that showed exceptional stability after more than 500 charge-discharge cycles. A high-current density of 20 milliamps per square centimeter demonstrated the material's promise for use in rapid charge and discharge devices that require high-power density. The Tour lab previously used a derivative of asphalt -- specifically, untreated gilsonite, the same type used for the battery -- to capture greenhouse gases from natural gas. This time, the researchers mixed asphalt with conductive graphene nanoribbons and coated the composite with lithium metal through electrochemical deposition. The lab combined the anode with a sulfurized-carbon cathode to make full batteries for testing. The batteries showed a high-power density of 1,322 watts per kilogram and high-energy density of 943 watt-hours per kilogram. Testing revealed another significant benefit: The carbon mitigated the formation of lithium dendrites. These mossy deposits invade a battery's electrolyte. If they extend far enough, they short-circuit the anode and cathode and can cause the battery to fail, catch fire or explode. But the asphalt-derived carbon prevents any dendrite formation.

"The capacity of these batteries is enormous, but what is equally remarkable is that we can bring them from zero charge to full charge in five minutes, rather than the typical two hours or more needed with other batteries," Tour said. "While the capacity between the former and this new battery is similar, approaching the theoretical limit of lithium metal, the new asphalt-derived carbon can take up more lithium metal per unit area, and it is much simpler and cheaper to make. There is no chemical vapor deposition step, no e-beam deposition step and no need to grow nanotubes from graphene, so manufacturing is greatly simplified." The findings have been published in the journal ACS Nano.

Dave Knott writes: The Nobel Prize in Chemistry was awarded on Wednesday to researchers who developed cryo-electron microscopy, which is described as a way to create detailed images of the molecules that drive life -- a technology that allows scientists to visualize molecular processes they had never previously seen. This is decisive for both the basic understanding of life's chemistry and for the development of pharmaceuticals. From the Nobel committee's press release: "Electron microscopes were long believed to only be suitable for imaging dead matter, because the powerful electron beam destroys biological material. But in 1990, Richard Henderson succeeded in using an electron microscope to generate a three-dimensional image of a protein at atomic resolution. This breakthrough proved the technology's potential. Joachim Frank made the technology generally applicable. Between 1975 and 1986 he developed an image processing method in which the electron microscope's fuzzy two-dimensional images are analyzed and merged to reveal a sharp three-dimensional structure. Jacques Dubochet added water to electron microscopy. Liquid water evaporates in the electron microscope's vacuum, which makes the biomolecules collapse. In the early 1980s, Dubochet succeeded in vitrifying water -- he cooled water so rapidly that it solidified in its liquid form around a biological sample, allowing the biomolecules to retain their natural shape even in a vacuum. Following these discoveries, the electron microscope's every nut and bolt have been optimized. The desired atomic resolution was reached in 2013, and researchers can now routinely produce three-dimensional structures of biomolecules."

According to Bloomberg, Facebook has for years fought to avoid being transparent about who's behind election-related ads online. "Since 2011, Facebook has asked the Federal Election Commission for blanket exemptions from political advertising disclosure rules -- transparency that could have helped it avoid the current crisis over Russia ad spending ahead of the 2016 U.S. election," reports Bloomberg. From the report: Communications law requires traditional media like TV and radio to track and disclose political ad buyers. The rule doesn't apply online, an exemption that's helped Facebook's self-serve advertising business generate hundreds of millions of dollars in political campaign spots. When the company was smaller, the issue was debated in some policy corners of Washington. Now that the social network is such a powerful political tool, with more than 2 billion users, the topic is at the center of a debate about the future of American democracy. Back in 2011, Facebook argued for the exemption for the same reasons as internet search giant Google: its ads are too small and have a character limit, leaving no room for language saying who paid for a campaign, according to documents on the FEC's website. Some FEC commissioners agreed, while others argued that Facebook could provide a clickable web link to get more information about the ad.

Facebook wouldn't budge. It warned that FEC proposals for more political ad disclosure could hinder free speech in a 2011 opinion written by Marc Elias, a high-powered Democratic lawyer who later became general counsel for Hillary Clinton's 2016 campaign. Colin Stretch, a top Facebook lawyer, said the agency "should not stand in the way of innovation," and warned that such rules would quickly become obsolete. When it came time for the FEC to decide in June 2011, the agency's six commissioners split on a 3-3 vote. Facebook didn't get its exemption, so an advertiser using its platform was still subject to a 2006 ruling by the FEC requiring disclosure. But the company allowed ads to run without those disclaimers, leaving it up to ad buyers to comply.

At its hardware event today, Google debuted new wireless earbuds, dubbed "Pixel Buds." These are Google's first wireless earbuds that give users access to Google Translate so they can have conversations with people who speak a different language. Ars Technica reports: Unlike Apple's AirPods, the Pixel Buds have a wire connecting the two earpieces. However, that wire doesn't connect to a smartphone or other device. Pixel Buds will pair via Bluetooth to the new Pixel smartphones -- and presumably any other devices that accept Bluetooth wireless earbuds. All of the Pixel Buds' controls are built in to the right earpiece, which is a common hardware solution on wireless earbuds. You can access Google Assistant by tapping or pressing on the right earbud, and the Assistant will be able to read notifications and messages to you through the Buds.

But the most intriguing feature of the Pixel Buds is the integrated Google Translate feature. Demoed on stage at Google's event today, this feature lets two Pixel Bud wearers chat in their native languages by translating conversations in real time. In the demo, a native English speaker and a native Swedish speaker had a conversation with each other, both using their native languages. Google Translate translated the languages for each user. There was barely any lag time in between the speaker saying a phrase and the Buds' hearing those words and translating them into the appropriate language. The Pixel Buds will use Google Translate to comprehend conversations in 40 different languages. Some other features include a 5-hour battery life, and a charging case that can hold up to 24 hours of battery life. They're available for preorder today for $159.

An anonymous reader quotes a report from Chicago Tribune: Getting through the workday on little sleep is a point of pride for some. But skimping on shuteye could be shortening your life and making you a less than stellar employee, according to Matthew Walker, founder and director of the Center for Human Sleep Science at the University of California, Berkeley. "Underslept employees tend to create fewer novel solutions to problems, they're less productive in their work and they take on easier challenges at work," said Walker, author of "Why We Sleep: Unlocking the Power of Sleep and Dreams," out Tuesday. Operating on short sleep -- anything less than seven hours -- impairs a host of brain and bodily functions, said Walker, who is also a professor of neuroscience and psychology. It increases your risk for heart attack, cancer and stroke, compromises your immune system and makes you emotionally irrational, less charismatic and more prone to lying. When asked, "What do you say to people who sacrifice sleep to work?" Walker said: "I often ask the question in return, 'Is the reason you've still got so much to do because you haven't gotten enough sleep and so you're inefficient while you're working?' We know that efficiency and effectiveness are increased when you're getting sufficient sleep and it will take you longer to do the same thing on an under-slept brain, which means you end up having to stay awake longer. So goes the vicious cycle."

AnalogDiehard writes: Congress created the Inter Partes Review (IPR) in 2012 within the U.S. Patent Office Patent Trials and Appeals Board (PTAB) as a faster and cheaper way to challenge and invalidate bad patents. The IPR expense is a fraction of the cost of a multimillion dollar patent court trial; it is loved by patent challengers and hated by patent owners. The pharmaceutical company Allergen has exploited a novel tactic to evade the IPR process: they hand them to a Native American Indian tribe for safekeeping. Under the arrangement, the tribes earn millions in royalties as long as the patents are valid, they license them back to Allergan, and the patents under the tribes' ownership is immune from lawsuits via sovereign immunity. Under the colonial-era concept of "sovereign immunity" which is codified in the 11th amendment, certain groups like states, universities, and tribes are immune from lawsuits, thus the drug patents are shielded from the IPR process leaving only a full blown multimillion dollar court trial for generic drug companies. This tactic is also attracting the attention of non-practicing entities -- the polite term for "patent trolls" -- and one such NPE company has already exploited sovereign immunity with the intention to sue Apple for infringement.

But court cases have limited the scope of sovereign immunity (especially for commercial activity), and now Congress is investigating Allergan over the tactic that has Congress not only greatly concerned about competition in the drug industry (and exorbitant prices of pharmaceuticals), but also the questionable use of the sovereign immunity law. The four lawmakers who signed the letter to Allergan state: "The unconventional maneuver has received considerable criticism from the generic competitors challenging the drug's patents under the process Congress created (IPR) to enable timelier review of such challenges (read: a fraction of the cost of a court trial)." The letter also notes that the key ingredient in the patent was set to expire in 2014 and that Allergan had filed more patents to extend patent protection to 2024, a signal that Congress is watching for exploitation of patent law to enable "perpetual patents" widely used by the pharmaceuticals.

In addition to the Pixel 2 and Pixel 2 XL, Google debuted a $400 speaker, called Home Max, that looks to compete directly with Apple's recently announced HomePod. The Home Max is a larger Google Home that features stereo speakers and more premium looks and materials. It's expected to go on sale in December in the U.S. TechCrunch reports: It can tune its audio to its own space, analyzing the sound coming from the speaker using its built in microphones to determine the best equalizer settings. This is called Smart Sound, and it evolves over time and based on where you move the speaker, using built-in machine learning. It has Cast functionality, as well as input via stereo 3.5 mm jack. Home Max can output sound that's up to 20 times more powerful than the standard version of Home, Google says, and it has two 4.5 inch woofers on board with two 0.7 inch custom-built tuners. It can sit in either vertical or horizontal orientation, and it comes in both 'chalk' and 'charcoal.' Of course, this bigger speaker also includes a noise isolating array that makes it work even in open rooms with background noise, and it's Assistant-enabled, so you can use it to control your music playback via voice, or manage your smart home devices, set yourself reminders, alarms, and timers and much more. Google also launched a budget-friendly Google Home Mini that features the Google Assistant but in a smaller form factor. 9to5Google reports: Google touts the Home Mini as having a powerful speaker with "crisp" 360 degree sound. The Mini can also be connected to any Chromecast wireless speaker, but there is no 3.5mm jack like Amazon's Echo Dot. In the center, there are four white lights that note when the Home Mini is listening or responding. Besides saying the "Ok, Google" hotword, users can tap on the Home Mini to issue a command. Google also retained the Home's original button for disabling the microphone with a toggle next to the charging port. The Google Home Mini will be go on sale later this month for $49, with pre-orders starting today.

An anonymous reader quotes a report from Reuters: The U.S. Senate Commerce Committee on Wednesday unanimously approved a bill to speed self-driving cars to market without human controls and bar states from imposing regulatory road blocks. The bill still must be approved by the full Senate. The U.S. House passed a similar version last month unanimously. General Motors Co, Alphabet Inc, Ford Motor Co and others have lobbied for the landmark legislation. Despite some complaints from Republicans, the Senate bill does not speed approval of self-driving technology for large commercial trucks after labor unions raised safety and employment concerns. The measure, the first significant federal legislation aimed at speeding self-driving cars to market, would allow automakers to win exemptions from current safety rules that prohibit vehicles without human controls. States could still set rules on registration, licensing, liability, insurance and safety inspections, but not performance standards.

LinkedIn co-founder Reid Hoffman joined other tech moguls in voicing concern about artificial intelligence on Wednesday. From a report: "It has great potential, but we need to steer carefully," Hoffman said on Halftime Report. Hoffman stressed corporate transparency when asked what happens if companies use AI to attack nation-states. The possibility of manipulating how people consume information remains an unanswered question. During last year's U.S. presidential election, Facebook advertisements linked to Russia mainly focused on the states of Michigan and Wisconsin, and Hoffman says information battles are "in the very early days." AI must be improved, Hoffman says, to "[hold] corporations accountable" when nation-states are using the technology to attack. "Corporations normally deal with other corporations, not with governments," Hoffman said. The "ultimate" solution, he says, is "having more kinds of functions and features within AI that show abhorrent patterns." That way patterns raise a red flag for humans to investigate, Hoffman noted.

Philip Blenkinsop, reporting for Reuters: The European Commission said on Wednesday it was taking Ireland to the European Court of Justice for its failure to recover up to 13 billion euros ($15.3 billion) of tax due from Apple, a move labeled as "regrettable" by Dublin. The Commission ordered the U.S. tech giant in August 2016 to pay the unpaid taxes as it ruled the firm had received illegal state aid, one of a number of deals the EU has targeted between multinationals and usually smaller EU states. "More than one year after the Commission adopted this decision, Ireland has still not recovered the money," EU Competition Commissioner Margrethe Vestager said, adding that Dublin had not even sought a portion of the sum.

Google is once again trying to make a big splash with laptop computers, this time with its new Pixelbook. From a report: Google debuted its Pixelbook, a new laptop-tablet hybrid during its Pixel 2 event in San Francisco on Wednesday, a high-end version of its barebones Chromebook laptops that rely on Google's Chrome operating system (OS). Google hopes its new Pixelbook, which sells for $999 to $1,649, will give it a viable challenger to Apple's MacBooks and other premium laptops. With Google's low-end Chromebooks, the company supplies the OS while third-party companies like HP Inc. and Dell build the devices. But Chromebooks are bulky, short on processing power, have limited storage, and are incompatible with Google's new Pixelbook stylus pen for drawing digital images on touchscreens. Matt Vokoun, Google's director for Chromebooks, emphasized that his company is serious about the Pixelbook. Although Google previously sold both high-end laptops and tablets, they were mostly "demonstration-oriented," he said, meaning Google didn't produce many of them and that they were instead for showing to potential manufacturers to get them on board with the idea.

New submitter TreZ writes: If you write software, you are most likely subject to a "security review" at some point. A large portion of this is common sense like don't put plain text credentials into github, don't write your own encryption algorithms, etc. Once you get past that there is a "subjective" nature to these reviews.

What is the worst "you can't do" or "you must do" that you've been subjected to in a security review? A fictitious example would be: you must authenticate all clients with a client certificate, plus basic auth, plus MFA token. Tell your story here, omitting incriminating details.

From a report: Google product chief Mario Queiroz today unveiled two new Android 8.1 Oreo smartphones at the company's annual hardware event: the Pixel 2 and the Pixel 2 XL. The smaller Pixel 2 sports a 5-inch, 1080p display, with a 16:9 aspect ratio that was until this year the standard on Android flagships. The larger Pixel 2 XL, meanwhile, has a 6-inch, QHD+ display in an 18:9 aspect ratio, in line with 2017's flagship smartphones. The Pixel 2 thus still has a large bezel while the Pixel XL 2 has a noticeably reduced bezel profile, although certainly not the smallest we've seen. As always, smartphone size also dictates battery capacity: 2700 mAh for the Pixel 2 and 3520 mAh for the Pixel 2 XL. Here's the rundown: Snapdragon 835 chipset, 4GB of RAM, either 64GB or 128GB of storage, an 8-megapixel front-facing camera, a 12-megapixel rear camera, front stereo speakers, a fingerprint scanner on the back, a USB-C port on the bottom, and no headphone jack. "Use your existing analog headphones with the included adapter," Queiroz said. [...] The HTC-manufactured Pixel 2 will be available in Just Black, Clearly White, and Kinda Blue on October 19. The LG-manufactured Pixel 2 XL will ship in Just Black and Black & White on November 15. The Pixel 2 will be available for $649 (64GB) and $749 (128GB) while the Pixel 2 XL will come in $849 (64GB) and $949 (128GB) flavors.

Andrada Fiscutean, writing for BleepingComputer: When cyber spies known as NetTraveler were busy snooping on hundreds of government and military victims in 40 countries a few years ago, little did they know that another hacking group was probably watching them. During their investigation of NetTraveler, Kaspersky Lab researchers discovered an unusual backdoor that could have helped another attacker access one of their main servers, and then use the group's infrastructure or steal data. In the past five years, cybersecurity experts have encountered several cases in which espionage groups likely pilfered one another's spoils, being interested in getting both data and hacking tools. Kaspersky Researchers Costin Raiu and Juan Andres Guerrero-Saade talked about such incidents on Wednesday during the Virus Bulletin 2017 Conference in Madrid, Spain. Government hackers sometimes "obtain data by stealing it from someone else, who took it in the first place from the victims," Raiu told Bleeping Computer in an email interview before the conference. He and Guerrero-Saade believe that citizens' personal data could fall into the hands of a foreign intelligence agency that's better equipped than the domestic one. The experts based their presentation on so far unpublished research that shows how spies walk off with other spies' data and tools, gaining valuable insight into a foreign service's intelligence collection methods, recruitment tactics, procedural guidelines, and the targets operatives have to monitor.

New submitter mirandakatz writes: Our relationships with most social media are sneakily transactional: We log onto Facebook or Instagram and wind up paying the platforms with our attention and ad clicks. A new social network aims to turn that on its head by paying users for their posts. Steemit runs on Steem, a cryptocurrency that currently has a market cap of $294 million -- and users have made more than $1.2 million in American dollars on the network. At Backchannel, Andrew McMillen takes a deep dive into Steemit, writing that 'By removing the middlemen and allowing users to profit directly from the networks they participate in, Steemit could provide a roadmap to a more equitable social network...Or users could get bored or distracted by something newer and shinier and abandon it. Fortunes could vanish at any moment, but someone stands to get rich in the process.'
