Lucas123 writes "According to MSNBC, scientists are experimenting with using a sperm's flagellum to overcome the problem of supplying energy to nanobots that could be implanted in the body as smart probes that would release disease-fighting drugs, monitor enzymes and perform other medical roles within a patient's body. Powered by a compound called adenosine triphosphate or ATP, a sperm's flagellum can propel it at about 7 inches an hour. Energy from ATP could also power the pumps charged with dispensing the medication at a certain rate from the nanobots."

Time Slows Down writes "Psychology Today has an interesting story on a new theory of why we dream. Finnish psychologist Antti Revonsuo believes that dreams are a sort of nighttime theater in which our brains screen realistic scenarios simulating emergency situations and providing an arena for safe training. 'The primary function of negative dreams is rehearsal for similar real events, so that threat recognition and avoidance happens faster and more automatically in comparable real situations,' he says. We have 300 to 1,000 threat dreams per year — one to four per night and just under half are aggressive encounters: physical aggression such as fistfights, and nonphysical aggression such as verbal arguments. Faced with actual life-or-death situations — traffic accidents, terrorist attacks, street assaults — people report entering a mode of calm, rapid response, reacting automatically, almost without thinking. Afterward, they often say the episode felt unreal, as if it were all a dream. 'Dreaming is a sensitive system that tries to pay much attention to the threatening cues in our environment,' Revonsuo says. 'Their function is to protect and prepare us.'"

chrisd writes "The Edge 2008 question (with answers) is in. This year, the question is: 'What did you change your mind about and why?'. Answers are featured from scientists as diverse as Richard Dawkins, Simon Baron-Cohen, George Church, David Brin, J. Craig Venter and the Astronomer Royal, Lord Martin Rees, among others. Very interesting to read. For instance, Stewart Brand writes that he now realizes that 'Good old stuff sucks' and Sam Harris has decided that 'Mother Nature is Not Our Friend.' What did Slashdot readers change their minds about in 2007?"

Glyn Moody writes "Google always plays down suggestions that there's any looming clash of the titans between itself and Microsoft. Meanwhile, the search giant is pushing open source in every way it can. They're contributing directly by contributing code to projects and employing top hackers like Andrew Morton, Jeremy Allison and Guido van Rossum, and indirectly through the $60 million fees it pays Mozilla, its Summer of Code scheme and various open source summits held at its offices. Google+OSS: could this be the killer combination that finally breaks Microsoft?"

Nathan Ramella writes "The ARCwelder project has released a technique dubbed 'Go Fighting Tabby!' which exploits an unquoted system() call through the Archos UI, providing the ability to execute arbitrary code with root access on the Archos 605 WiFi. In doing so, opening the platform up for further hacking. The Archos 605 WiFi runs embedded Linux on an ARM processor, but employs a variety of anti-hack techniques to keep users from modifying its firmware and operating system. Included is a cross-compiled sshd with configuration files to allow for passwordless ssh access to the Archos when it is connected to a WiFi connection. Bricks ahoy!"

Googling Yourself writes "Lifehacker has an interesting blog post on the 'Top 10 Google Products You Forgot All About' that includes stalwarts like Google Trends and Google Alerts and a few others that may not be quite so familiar like Google Personals, Google's WYSIWYG web site creation tool, and Flight Simulator for Google Earth."

WheezyJoe writes "Maybe OS X Leopard has its problems, but the New York Times seems to think Apple has designed the ideal techie retail store. A policy that encourages lingering, with dozens of fully functioning computers, iPods and iPhones for visitors to try, even for hours on end (one patron wrote a manuscript entirely at the store) has 'given some stores, especially those in urban neighborhoods, the feel of a community center ... Meanwhile, the Sony flagship store on West 56th Street, a few blocks from Apple's Fifth Avenue store, has the hush of a mausoleum. And being inside the long and narrow blue-toned Nokia store on 57th Street feels a bit like being inside an aquarium. The high-end Samsung Experience showroom, its nuevo tech music on full blast one recent morning, was nearly empty.'"

Ponca City, We Love You writes "Daily Domainer has a story alleging that there may be a leak that allows domain tasters to intercept, analyze and register your domain ideas in minutes. 'Every time you do a whois search with any service, you run a risk of losing your domain,' says one industry insider. ICANN's Security and Stability Advisory Committee (SSAC ) has not been able to find hard evidence of Domain Name Front Running but they have issued an advisory (pdf) for people to come forward with hard evidence it is happening. Here is how domain name research theft crimes can occur and some tips to avoiding being a victim."

An anonymous reader writes "PC Magazine reviews the $200 Linux desktop wonder sold by Wal-Mart. This desktop sold out quickly and has been cited as proof that consumers are tired of the Windows tax and ready for Linux. Not so according to PC Magazine, which gave the gPC a 1.5 star rating." Previous discussions we've had about system reviews were realistic but not quite so harsh; is this just nitpicking or is the 'shiny' starting to wear off of the cheap Linux PC concept?

greg65535 writes "Today Microsoft launched a blog about the internals of their IT security research and patch development process. There are already some posts that you will not find in the official security bulletins or KB articles. One of the posts says, 'We periodically identify workarounds or mitigations like this that we can't use for official guidance because they're either too nuanced or have some exception cases. When we discover something potentially useful but are uncomfortable listing it in the bulletin, we'll do our best to describe it here in this blog.' It looks like Microsoft is making an effort to become more 'open' in the area of security research and communication."

An anonymous reader writes "The Apple iMac is probably the standard all-in-one desktop computer. Great operating system, built-in software and design around solid, but pretty normal, hardware guts. According to Walter Mossberg, there's a new kid in town that not only matches it but is 'sightly ahead': the Dell XPS One. His latest review is already causing the usual suspects to weigh in. Mossberg says it is a better machine, but Vista and its built-in software make it inferior than Apple iMac's Leopard and iLife suite. Would you choose the better hardware of the Dell XPS One -which is more expensive- or the elegant design and software of the Apple iMac?"

coondoggie writes "The FBI today said it wants to install 150 digital billboards in 20 major U.S. cities in the next few weeks to show fugitive mug shots, missing people and high-priority security messages from the big bureau. The billboards will let the FBI highlight those people it is looking for the most: violent criminals, kidnap victims, missing kids, bank robbers, even terrorists, the FBI said in a release. And the billboards will be able to be updated largely in real-time — right after a crime is committed, a child is taken, or an attack is launched. Chicago, Las Vegas, Los Angeles and Miami will be among those cities provided with the new billboards."

An anonymous reader writes "My company is building a new office. As the local IT Guy, I've been asked to design my new office from the ground up. If you were given the opportunity to design your dream office, what features would you include? What things would you try to avoid? I get to determine absolutely everything. The catch? I have to share my office space with all the network equipment. Just 4 standard racks, and all your basic telephone and network wiring. Can anyone help me get started? I have no idea where to even begin."

I Don't Believe in Imaginary Property writes "Frustrated at the FTC's blessing of the Google/Doubleclick merger, Microsoft is complaining to the EU. Its latest filings detail how the merger would give Google a stranglehold on the advertising industry. While these complaints aren't new, the diagram [PDF] Microsoft created gives you an interesting look at the sort of competition Microsoft fears from Google."
