- Opposable Thumbs and Upright Walking Caused By "Junk DNA"
quinnlynn writes "A group of research scientists at Yale discovered that the evolution of opposable thumbs and upright walking in humans is due to changes in the genome in the areas still classified as "junk DNA." Quoting: 'Results from a comparative analysis of the human, chimpanzee, rhesus macaque and other genomes reported in the journal Science suggest our evolution may have been driven not only by sequence changes in genes, but by changes in areas of the genome once thought of as "junk DNA." ... Researchers have long suspected changes in gene expression contributed to human evolution, but this had been difficult to study until recently because most of the sequences that control genes had not been identified. In the last several years, scientists have discovered that non-coding regions of the genome, far from being junk, contain thousands of regulatory elements that act as genetic "switches" to turn genes on or off.'" Yale has also recently completed sequencing the Trichoplax genome. Trichoplax has the simplest known animal genome, and it shares 80 percent of its genes (comprised of 98 million base pairs) with humanity. Professor Stephen Dellaporta was quoted saying, "We are [excited] to find that Trichoplax contains shared pathways and defined regulatory sequences that link these most primitive ancestors to higher animal species. The Trichoplax genome will serve as a type of 'Rosetta Stone' for understanding the origins of animal-specific pathways."

- Cell Phone For the Blind?
brigc writes "Here's one that's got me stumped. A friend of mine who is blind asked me for help tracking down a cell phone for him. He's interested in a flip phone with well-defined separations between the keys, and as much voice control as possible. Battery life is the only other thing he mentioned. Preferably something that would work on AT&T's network in the US. We spent part of the afternoon in a local AT&T store checking out all the flip phones they had and didn't find one he really loved. Anyone have any ideas?" There was a story some months back about a phone that would read to you by interpreting pictures from the built-in camera, but it doesn't have much information about usability. I'm sure it'd be handy to have some sort of text-to-speech option for common cell phone features like caller ID and text messaging, or even just reading menu names.

- Promotion To Send Gamers' DNA to Space
Bridger tips news that NCSoft's Tabula Rasa, created in part by Richard Garriott, is running an unusual promotion right now. Garriott is going to the International Space Station on October 12th, and he'll take with him a digital record of the DNA of various players and celebrities. The basic plot of Tabula Rasa is that Earth was attacked and humans almost completely wiped out. Garriott's promotion is playing on that idea; the hard drive with the DNA data will be left in orbit "just in case" something happens to humanity on Earth. NCSoft has been running a variety of polls and contests to include further data about humans on the hard drive. The deadline for joining the project has recently been extended to September 29th.

- Is the US Ready For the Switch To DTV?
tonsofpcs writes "On Monday, September 8, Wilmington, NC will be the first television market (#135) to make the switch to DTV by shutting off their analog transmitters. This forum will be posting updates throughout the coming months to keep everyone updated on how the transition works so that we are all prepared come February 17, 2009. So far, it seems Wilmington will still be going ahead as planned, despite Tropical Storm Hanna's proximity."

- Why Is the Internet So Infuriatingly Slow?
Anti-Globalism writes "The major ISPs all tell a similar story: A mere 5 percent of their customers are using around 50 percent of the bandwidth, sometimes more, during peak hours. While these 'power users' are sharing three-gig movies and playing online games, poor granny is twiddling her thumbs waiting for Ancestry.com to load."

- Canadian Researchers Say Hard Thinking Leads to Big Meals
Anti-Globalism writes with an excerpt from a story at Ars Technica, according to which "a preliminary study from a group of researchers in Quebec suggest that working on a computer may have an additional impact on our waistlines: taxing mental effort appears to cause people to eat significantly more food, even though it doesn't burn many more calories than sitting around and relaxing. The publication, published in a journal called Psychosomatic Medicine, arose from a pilot study that the researchers were performing in order to determine whether a potential connection between mental effort and eating was worth following up on."

- TCP/IP Meets Physical Reality
An anonymous reader writes "When Google is clouding the borderline between web and the desktop, a much, much smaller project is blurring the border between the Internet and the physical reality: the newly released Contiki operating system version 2.2.1. Contiki runs on networked wireless sensors that are used for anything from road tunnel monitoring for fire rescue operations to collecting vital statistics from ice hockey players. These sensors typically have as little as a few kilobytes of memory and a few milliwatts of power budget — a thousandth of the resources of a typical PC computer — yet Contiki provides them with full TCP/IP connectivity. Meanwhile, San Francisco is monitoring parking spaces with wireless technology."

- Russian Google Competitor Embraces Open Source Messaging
rm writes "Internet search and mail provider Yandex, which many view to be Google's main competitor in Russia, has recently added an instant messaging capability to its mail notifier application Ya.Online. As it turns out, the IM service is based on the open XMPP protocol, with connectivity to all other public Jabber servers available from day one. MacOS X and GNU/Linux versions of the app were also released (complete with sources under the GPL) and are determined to be based on the Psi IM client. Yandex looks to be a firm believer in open-source, also running a mirror site for FOSS and actively promoting its branded version of Firefox. Here's hoping that its affair with XMPP will help eliminate ICQ's enormous foothold in Russia."

- Wi-Fi, Now Available On the ISS
Grant Henninger writes "Rejoice! The next time you have an extra $20 million and decide to visit the International Space Station you won't need to leave the window to tell all your friends how cool it is. The ISS now has a new Wi-Fi network, so all you'll need to do is fire up Twitterrific and announce how much better you are than your Earth-based friends."

- Hacker Conventions Ranked By Bandwidth-Per-Visitor
Anonymous Coward writes "Ever wondered how much bandwidth you will get at a hacker con? This web page tells you how much. It shows the total bandwidth and bandwidth for each visitor for all the recent hacker cons." It looks like Defcon attendees get the short end of the stick, while those at metarheinmain chaosdays are practically swimming in bandwidth. There are a lot of other cons (a few examples listed here) which I'd like to see added to this list.

- amp;T Slaps Family With a $19,370 Cell Phone Bill
theodp writes "Mama, don't let your babies send e-mail and photos from Vancouver. A Portland family racked up nearly $20,000 in charges on their AT&T bill after their son headed north to Vancouver and used a laptop with an AirCard twenty-one times to send photos and e-mails back home. The family said they wished they would have received some kind of warning before receiving their chock-full-of-international-fees 200-page bill in the mail for $19,370. Guess they didn't read the fine print in that 'Stay connected whether you are traveling across town, the US, or the world' AT&T AirCard pitch. Hey, at least it wasn't $85,000."

- Identifying a Culprit In a Bloodbath
worromot writes "A group of geneticists published a method to determine if a given individual's DNA is present in a mixture (e.g., in a pool of blood on a carpet). An individual's DNA can comprise less than 1% of the mixture. (The article is in open access on PLoS Genetics website.) While this is a potential boon for forensics, there are more immediate worries about the privacy of the participants of the genetics studies that had been under way for many years. As Science magazine writes, 'The discovery that a type of genetic data that is widely shared and often posted online can be traced back to individuals has prompted the US National Institutes of Health and the Wellcome Trust to strip some genetic data from their publicly accessible Web sites and NIH to recommend that other institutions do the same.' The gravest worry was that an individual who had someone's genetic code could determine, based on the pooled data, whether the person participated in a disease study and whether they were in the disease group, or thereby glean private health information. NIH plans to ask institutions that have posted pooled data on their own Web sites to take these down, too."

- The Great Zero Challenge Remains Unaccepted
An anonymous reader writes "Not even data recovery companies will accept The Great Zero Challenge and only four months remain! We've all heard how easily data can be recovered from hard drives. We're told to make multiple overwrites with random data, to degauss drives and even physically destroy them just to be extra safe. Let's get the word out. The challenge is almost over! It's put up or shut up time. Can you recover the data?"

- The Google Navy
theodp writes "Is Google preparing to launch its own Navy? In its just-published application for a patent on the Water-Based Data Center, Google envisions a world where 'computing centers are located on a ship or ships, which are then anchored in a water body from which energy from natural motion of the water may be captured, and turned into electricity and/or pumping power for cooling pumps to carry heat away from computers in the data center.' And you thought The Onion was joking when it reported on Google's Fleet of Naval Warships!"

- Sarah Palin's Stance On Technology Issues
Revolution Radio writes "BetaNews has a short description of what we might expect from Governor Palin regarding technology issues. She demonstrated her familiarity with the internet by initiating an online education program for state workers, using the web for government transparency, and a supporting the general concept of 'long-distance distribution of services' (similar to net neutrality?)." We've previously discussed Senator Joe Biden's tech voting record and compared the technology platforms of Obama and McCain. In addition to the above story about Palin, Betanews also has analyses of Obama, McCain, and Biden regarding tech policy.
