sciencehabit writes with this except from Science: "You may not give a lot of thought to what happens inside the battery of your laptop or cell phone, but to judge from this video, it's not a dull place. The battery in question is a miniature rechargeable lithium-ion device, and the clip shows what happens when it is charged. As lithium ions flow from the positively charged cathode into the 200-nanometre diameter wires of tin oxide that make up the negatively charged anode, the nanowires writhe and bulge, causing them to expand up to 2.5 fold. The wires also change structure from a neatly ordered crystal to a disordered glassy material. These distortions may explain why such batteries ultimately wear down. Knowing more about the process may help researchers develop longer lasting, and perhaps much smaller, batteries in the future."

alphadogg writes "At Microsoft, Hewlett-Packard and IBM, investment in research and development is a reflection of corporate culture. This three-part piece by the IDG News Service examines the different approaches taken by each of these influential tech companies. Hewlett-Packard prides itself on its pragmatism, while Microsoft holds the flag of basic research aloft — and IBM continues to file more patent applications, year after year, than any other tech company."

sciencehabit writes "Where did Earth's oceans come from? Astronomers have long contended that icy comets and asteroids delivered the water for them during an epoch of heavy bombardment that ended about 3.9 billion years ago. But a new study suggests that Earth supplied its own water, leaching it from the rocks that formed the planet. The finding may help explain why life on Earth appeared so early, and it may indicate that other rocky worlds are also awash in vast seas."

theodp writes "Looks like threatening to take their ball and leave paid off for US tech firms. The Irish government announced plans this week to tap the welfare state and working class for much of the $20B in savings they've pledged to find over the next four years, but the austerity measures will not touch large businesses like Microsoft, Intel, Google, HP, Facebook, LinkedIn, and Pfizer, which created jobs and fueled exports in Ireland after being lured by low corporate tax rates. More than 100,000 Dubliners took to the streets to protest the bailout plan, calling for the Irish government to default on the country's debts, and demanding an immediate election. 'We should default,' said a retired union worker, 'the idea that the workers of this country should pay for the gambling of the billionaires is disgusting.'"

theodp writes "The Irish government has been given a stark warning from some of the biggest American companies in Ireland on the risk of a mass exodus if the country's controversial low corporate tax rate is raised in return for an IMF/EU bailout to shore up the country's beleaguered banking system. According to The Telegraph, a statement signed by senior execs at Microsoft, HP, Bank of America, Merrill Lynch, and Intel points out that although Ireland's tax rate may be low in European terms, it is not when compared with locations such as Singapore, India and China. Separately, the head of Google's 2,000-strong European HQ in Dublin told the Belfast Telegraph, 'anything that impinges on Ireland's competitiveness is going to be a big thing for Google,' adding, 'anything that increases the cost-base of a business is negative for competitiveness.'"

Ponca City writes "Chris O'Brien writes in the Merucry News that Larry Ellison's lawsuit against bitter rival SAP gives Ellison the opportunity to deliver the final humiliation to his company's greatest foe of the past decade while sending a blunt message to Oracle's next great enemy, Hewlett-Packard: 'This is who you are fighting. This is how determined we are to win. Get ready.' O'Brien writes that it's a crafty bit of psychological warfare that is already having the desired effect. When Oracle decided to subpoena former SAP CEO Léo Apotheker after he was appointed president and CEO of HP, Apotheker decided to stay out of the country to avoid testifying so now we have the bizarre spectacle of the new CEO of the largest technology company in the world unable to show his face in Silicon Valley. Ellison loves to fight. In gaining control of PeopleSoft, Ellison demonstrated the love of combat and confrontation that has made him one of the wealthiest men on the planet. He waged an 18-month hostile takeover bid to acquire the company, and fought off an effort by the US Department of Justice to torpedo the deal. 'Oracle probably could have settled this case [with SAP],' writes O'Brien. 'But why pass up a glorious chance to subpoena Apotheker and send your new opponent running in circles?'"

Shortly after the launch of Google TV, it became clear that several networks and services were blocking access. Reader padarjohn points out a blog post from Lauren Weinstein explaining the blocking mechanisms being used and wondering why it's being tolerated. "Imagine the protests that would ensue if Internet services arbitrarily blocked video only to Internet Explorer or Firefox browsers! Or if Hulu and the other networks decided they'd refuse to stream video to HP and Dell computers because those manufacturers hadn't made deals with the services to the latter's liking." Various workarounds are being used to get around the blocks.

theodp writes "Oracle said HP has refused to accept a subpoena requiring new CEO Leo Apotheker to testify in a trial against his former employer SAP, which will determine how much SAP owes Oracle for copyright infringement by its discontinued TomorrowNow unit. 'Mr. Apotheker started work for HP on Monday, but it now appears that the HP board of directors has decided to keep him away from HP's headquarters and outside the court's jurisdiction,' an Oracle spokeswoman said. 'We will continue to try to serve him,' she added. An HP spokeswoman countered: 'Given Leo's limited knowledge of and role in the matter, Oracle's last-minute effort to require him to appear live at trial is no more than an effort to harass him and interfere with his duties and responsibilities as HP's CEO.' The spokeswoman declined to discuss the whereabouts of Mr. Apotheker, who was featured in a 2006 SAP/TomorrowNow press release attacking the 'uncertainty' of Oracle. Coincidentally, among the charges leveled at SAP/TomorrowNow was 'pretextual customer log-in,' an area in which HP has some subject matter expertise."

eldavojohn writes "As a gold member, China Mobile has joined The Linux Foundation putting it next to AMD, Google, HP and Cisco in the roster of the foundation's gold members. This marks the very first time a Chinese enterprise has joined The Linux Foundation. Earlier this year, we saw the first Chinese company openly participate in open source and now China Mobile, ranked 77th in the world by Fortune with over half a billion customers, has joined the foundation that fosters the growth of Linux."

sciencehabit writes "It's not quite the flickering blue projection of Princess Leia begging, 'Help me, Obi-Wan Kenobi, you're my only hope!' from the classic sci-fi movie Star Wars, but holographic projection has just beamed a bit closer to reality. Researchers in Arizona have devised a novel plastic film that can be used to generate holographic 3D images sent electronically from one location to another. The technology opens the door for everything from holographic surgery to movies that literally surround the viewer."

adeelarshad82 writes "According to recent reports, a Google-branded Chrome OS notebook will be launched by Inventec later this month. Acer and HP will be launching theirs a month later, in December. This report is also backed by a source close to Google stating that the company is still on track to launch its Chrome OS by the end of the year, as well as its Chrome app store."

At this year's Blizzcon, we got to try out a section of Diablo 3 that was pulled directly from the single-player storyline and playable with all classes. A large number of skills and abilities were playable, and the skill rune system has been implemented, a feature that was lacking for last year's demo build. We also got to spend some time trying out the newly announced PvP system — Battle Arenas. Read on for a walk-through of Diablo 3 as we've seen it so far. In short: it's shaping up to be an excellent game, and a worthy successor to Diablo 2. Read on for more.

rheotaxis writes "Many professional web developers have spent years building dynamic, database-driven web applications, but some of us, like myself, want to make the user experience more interactive and instantaneous. The book Building the Realtime User Experience, by Ted Roden, is an introduction to some new techniques making that happen now. New web servers like Cometd and Tornado power solutions that keep HTTP connections open until data is available for the clients requesting it, a technique called 'long-polling.' This means web developers can provide a real-time user experience using HTTP for all sorts of client devices now connecting to the Internet, not just web browsers, but mobile devices as well." Read below for the rest of rheotaxis's review.

judgecorp writes "Microsoft CEO Steve Ballmer told an audience at the London School of Economics, that there will be tablets running Microsoft's Windows operating system available by Christmas. 'We as a company will need to cover all form factors,' he told an audience of students and press. 'You'll see slates with Windows on them – you'll see them this Christmas.' Mind you, if he's talking about the rumoured HP Windows 7 slate, he may not be so pleased when it appears. A recent YouTube video showed a supposed prototype which has been described as a 'trainwreck in the making.'"

theodp writes "Valleywag reports that ousted HP CEO Mark Hurd is paying dearly to roll with Oracle, giving up millions of dollars to settle the HP lawsuit that threatened to prevent him from working at his new job. Hurd will forfeit about 345,000 restricted HP shares that he was given as part of his HP exit package, which had a market value of $13.6 million. In addition to announcing the truce against the backdrop of Oracle's OpenWorld conference, HP and Oracle also reaffirmed their vows to each other."

angry tapir writes "Hewlett-Packard showed off a tablet computer that serves as a control panel for its new printer. The tablet browses the Web and can be used as an e-reader. It has a 7-inch screen and can be easily connected to HP's PhotoSmart eStation all-in-one printer. The tablet can be used to move and print documents and images from multiple media devices and can also be used to exchange content between the devices. The display is a larger version of the 3.5-inch control panel screens on HP's earlier Web-connected printers. The device is focused on providing access to content that can be printed, such as photos, articles, e-mail, recipes or e-books."

An anonymous reader writes "HP and ArcSight have signed a definitive agreement for HP to acquire ArcSight, a security and compliance management company, for $43.50 per share, or an enterprise value of $1.5 billion. The acquisition will be conducted by means of a cash tender offer for all of ArcSight's outstanding shares of common stock. The closing of the acquisition, which is subject to customary closing conditions, is expected to occur by the end of the calendar year."

CWmike writes "Hewlett-Packard is reported to be suing former CEO Mark Hurd, who was named co-president of rival Oracle on Monday. The Wall Street Journal first reported the news, and has now posted the full text of the suit on Google Docs. Among other things, it says, 'In his new positions, Hurd will be in a situation in which he cannot perform his duties for Oracle without necessarily using and disclosing HP's trade secrets and confidential information to others.'"

theodp writes "Late on Monday, Oracle announced that ousted HP CEO Mark Hurd has joined the company as a co-president and a director. Hurd resigned from HP a month ago, after an investigation by the board into a personal relationship with a contractor turned up questionable expenses. Oracle CEO Larry Ellison, a personal friend of Hurd, criticized HP's board at the time, saying it was 'the worst personnel decision since the idiots on the Apple board fired Steve Jobs.' 'Mark did a brilliant job at HP and I expect he'll do even better at Oracle,' Ellison said in a statement Monday. 'There is no executive in the IT world with more relevant experience than Mark.' Stepping down to make room for Hurd was Charles E. Phillips Jr., who had some personal relationship issues of his own."

Stoobalou writes "A member of Iceland's parliament and prominent organizer for whistle-blowing website WikiLeaks has turned on the site's spokesman, Julian Assange, urging him to step down over rape allegations made against him in Sweden. Birgitta Jonsdottir told news site The Daily Beast that she did not believe Assange's repeated assertion that the allegations of rape and molestation made against him were part of a US-backed smear campaign to distract attention from documents posted on the site laying bare US involvement in the war in Afghanistan and further promised revelations."
