New Electrode Lets Batteries Charge In 10 Seconds 348

Al writes "A new lithium-ion electrode allows batteries to be charged and discharged in 10 seconds flat. Developed by Gerbrand Ceder, a professor of materials science at MIT, it could be particularly useful where rapid power bursts are needed, such as for hybrid cars, but also for portable electronic devices. In testing, batteries incorporating the electrodes discharged in just 10 seconds. In comparison, the best high-power lithium-ion batteries today discharge in a minute and a half, and conventional lithium-ion batteries, such as those found in laptops, can take hours to discharge. The new high rate electrode, the researchers calculate, would allow a one-liter battery based on the material to deliver 25,000 watts, or enough power for about 20 vacuum cleaners."

Obama Team Considers Cancellation of Ares, Orion 870

HanzoSpam sends us this story from Space News, which begins: "US President-elect Barack Obama's NASA transition team is asking US space agency officials to quantify how much money could be saved by canceling the Ares 1 rocket and scaling back the Orion Crew Exploration Vehicle next year. ... The questionnaire, 'NASA Presidential Transition Team Requests for Information,' asks agency officials to provide the latest information on Ares 1, Orion and the planned Ares 5 heavy-lift cargo launcher, and to calculate the near-term close-out costs and longer-term savings associated with canceling those programs. The questionnaire also contemplates a scenario where Ares 1 would be canceled but development of the Ares 5 would continue. While the questionnaire, a copy of which was obtained by Space News, also asks NASA to provide a cost estimate for accelerating the first operational flight of Ares 1 and Orion from the current target date of March 2015 to as soon as 2013, NASA was not asked to study the cost implications of canceling any of its other programs, including the significantly overbudget 2009 Mars Science Laboratory or the James Webb Space Telescope."

Ray Kurzweil Wonders, Can Machines Ever Have Souls? 630

Celery writes "There's an interview with Ray Kurzweil on silicon.com talking up the prospects of gene therapy as a means to reverse human aging, discussing different approaches to developing artificial intelligence, and giving his take on whether super intelligent machines could ever have souls. From the interview: 'The soul is a synonym for consciousness ... and if we were to consider where consciousness comes from we would have to consider it an emerging property. Brain science is instructive there as we look inside the brain, and we've now looked at it in exquisite detail, you don't see anything that can be identified as a soul — there's just a lot of neurons and they're complicated but there's no consciousness to be seen. Therefore it's an emerging property of a very complex system that can reflect on itself. And if you were to create a system that had similar properties, similar level of complexity it would therefore have the same emerging property.'"

(Useful) Stupid BlackBerry Tricks? 238

Wolfger writes "Continuing the recent (useful) stupid theme: I've recently become a BlackBerry user, and I'm in love with the obvious(?) tricks, such as installing MidpSSH to access my home box remotely. But I'd like to know what more experienced Crackberry addicts can share."

OpenSolaris 2008.11 – Year of the Laptop? 223

Ahmed Kamal writes "Is Linux getting too old for you? Are you interested to see what other systems such as OpenSolaris have to offer? OpenSolaris has some great features, such as ZFS and dtrace, which make it a great server OS — but how do you think it will fare on a laptop? Let's take an initial look at the most recent OpenSolaris 2008.11 pre-release on recentish laptop hardware."

Linux Kernel Surpasses 10 Million Lines of Code 432

javipas writes "A simple analysis of the most updated version (a Git checkout) of the Linux kernel reveals that the number of lines of all its source code surpasses 10 million, but attention: this number includes blank lines, comments, and text files. With a deeper analysis thanks to the SLOCCount tool, you can get the real number of pure code lines: 6.399.191, with 96.4% of them developed in C, and 3.3% using assembler. The number grows clearly with each new version of the kernel, that seems to be launched each 90 days approximately."

Web Singletons? 254

tcmb writes "There are an uncounted number of web mail and picture sharing services, there are more than enough web sites for online bookmark management and friend-finding, but as far as I know there is only one Internet Archive. Which are the true web singletons, services that exist only once in this form?" And does anything approach the singular time-wasting abilities of IMDB or Wikipedia?

Mars Lander Instrument Waving In the Martian Wind 46

Matt_dk writes "This series of images show Phoenix's telltale instrument waving in the Martian wind. Documenting the telltale's movement helps mission scientists and engineers determine what the wind is like on Mars. On the day these images were taken, one of the images seemed to be 'out-of-phase' with other images, possibly indicating a dust devil occurrence."

Colliding Galaxies Reveal Colossal Black Holes 134

Matt_dk writes "New observations made with the Submillimeter Array of telescopes in Hawaii suggest that black holes — thought to exist in many, if not all, galaxies — were common even in the early Universe, when galaxies were just beginning to form. Astronomers have found two very different galaxies in the distant Universe, both with colossal black holes at their hearts, involved in a spectacular collision."

Android Also Comes With a Kill-Switch 300

Aviran writes "The search giant is retaining the right to delete applications from Android handsets on a whim. Unlike Apple, the company has made no attempt to hide its intentions, and includes the details in the Android Market terms and conditions, as spotted by Computer World: 'Google may discover a product that violates the developer distribution agreement... in such an instance, Google retains the right to remotely remove those applications from your device at its sole discretion.'"

Soyuz With Richard Garriott Successfully Launched 56

Toren Altair writes "Soyuz TMA-13 with ISS Expedition Crew 18 and Richard Garriott successfully launched from Baikonur Cosmodrome at 7:01 UT (3:01 EDT). The Soyuz capsule will dock to the ISS in two days. Garriott will return to Earth with Expedition 17 crew members, Commander Sergei Volkov and Flight Engineer Oleg Kononenko on October 23." With the extra attention on this launch, the Russians have gone out of their way to say that the return of the Soyuz vehicle will be safe, after a couple of different malfunctions in the past year. Garriott is in space partly for recreation, and partly as a promotion for his latest MMO, Tabula Rasa. He took with him a hard drive filled with information about humanity, as well as DNA sequences from Tabula Rasa players and various celebrities (including Stephen Colbert and Stephen Hawking) to 'preserve' that data in case of a disaster on Earth. Garriott will also spend time running and participating in experiments. Coverage of the Soyuz mission is ongoing at NASATV.

Slashdot's Disagree Mail 202

Slashdot has one of the best discussion systems there is. It's grown and adapted over the years to meet various challenges and suit the needs of our users. A lot of time and effort has gone into it and we are always open to user input to help make it better. Some of our best ideas start as user suggestions and we appreciate the feedback. Of course they can't all be gems and sometimes the suggestions we get are unworkable or just bizarre. Here are a few of my favorite unhelpful, helpful suggestions.

Google Brings Ads To Games, Game Ads To YouTube 108

Reuters reports that YouTube will be partnering with Amazon and iTunes to provide the ability to purchase games and songs that are in or related to YouTube's hosted videos. For example, watching footage from Spore will bring up a link to purchase the actual game through Amazon. The sales revenue will be shared. In related news, Google has launched a public beta for their in-game advertising software based on Adsense. "Google is initially targeting the sweet spot for its technology: games based in Adobe's Flash platform and which run in a web browser with no download. ... [Christian Oestlien, senior product manager at Google] said that Google's advertisers can use the software to insert ads into games or videos for YouTube, making the ads more versatile. Developers of games can use Flash software development kits to designate the points in a game that make an 'ad request.'"
