carusoj writes "Squatting on domain names is nothing new, but Twitter has created a new opportunity for squatters, in the form of Twitter IDs. Writes Richard Stiennon: 'Is there evidence of Twitter squatting (squitting?) Let's check. Yup, every single-letter TwitID is taken ... How about common words? Garage, wow, war, warcraft, Crisco, Coke, Pepsi, Nike, and Chevrolet are all taken. My guess is that Twitter squatters have grabbed all of these in the hopes that they will be worth selling in the not too distant future. Of course the legitimate holders of brands can sue for them and Twitter can just turn them over if asked. But, because the investment and risk for the squatter is zero, you are going to see the rapid evaporation of available Twitter IDs.'"

Hugh Pickens writes "Contrary to previous beliefs, identical twins are not genetically identical. Researchers studied 19 pairs of monozygotic, or identical, twins and found differences in copy number variation in DNA which occurs when a set of coding letters in DNA are missing, or when extra copies of segments of DNA are produced. In most cases, variation in the number of copies likely has no impact on health or development but in others, it may be one factor in the likelihood of developing a disease (pdf). "Those differences may point the way to better understanding of genetic diseases when we study so-called discordant monozygotic twins....a pair of twins where one twin has a disorder and the other does not," says Carl Bruder, Ph.D. "If twin A develops Parkinson's and twin B does not, the region of their genome where they show differences is a target for further investigation to discover the basic genetic underpinnings of the disease.""

AnonymousHack writes "New Scientist examines why people are in general more rude and abusive online. 'Psychologically, we are "distant" from the person we're talking to and less focused on our own identity. As a result we're more prone to aggressive behavior' says one psychologist, who also cites research showing messages received by email are always perceived more negatively than on the phone." Just more proof for the Greater Internet F***wad Theory.

mattnyc99 writes "PopularMechanics.com takes a peek into the growing world of high-tech piracy on the open seas, which the U.S. Navy and Coast Guard are looking to cut off by investing in a new fleet of superfast, gun-mounted unmanned surface vessels (USVs). From the article: "The Interceptor is available now. But the USV market is just getting started: Two months ago, British defense firm Qinetiq debuted its own robotic vessel, the jetski-size Sentry. Among its potential duties is intruder investigation, which could include scouting out unidentified boats, along the lines of the raft that detonated alongside the USS Cole in Yemen, as well as offering a first look at a possible pirate-controlled vessel.""

Apple just announced new iMacs. They are aluminum and come in 20" (two models) and 24". There's a new view called "Events" in iPhoto that should make it easier to deal with large photo libraries. Apple's .Mac service is enhanced with .Mac Web Gallery, which integrates with the new iTunes and also the iPhone. It's a Web 2.0 app now. And iMovie is being replaced by a completely new app of the same name. Steve Jobs claimed that with it you can put together a 5-minute movie in 30 minutes, and he demo'ed that from the stage. iWeb, iDVD, and GarageBand get new features too. And .Mac subscribers get 10 GB of storage. Here is Engadget's blow-by-blow coverage, and Wired's.

Tech.Luver sends us to The Inquirer, which notes the banning of all gambling in Second Life. Here is the Linden Labs blog post about the change in policy, which is, to say the least, not popular. From the article: "[T]he large chunk of users that enjoyed using in-world casinos and betting Linden Dollars on events both inside and outside the game world will now have nothing left to do. Perhaps more to the point for Linden, the move will cut off the revenues earned from those owning Casino-style islands in the game, the owners of which are some of the top contributors to the Linden coffers through currency fees and land rental."

theodp writes "Debunking claims to the contrary, a new study from Duke University asserts that it is purely cost savings, and not the education of Indian and Chinese workers, or a shortage of American engineers that has caused offshore outsourcing. 'The key advantage of hiring Chinese entry-level engineers was cost savings, whereas a few respondents cited strong education or training and a willingness to work long hours. Similarly, cost savings were cited as a major advantage of hiring Indian entry-level engineers, whereas other advantages were technical knowledge, English language skills, strong education or training, ability to learn quickly, and a strong work ethic.' The article goes on to point out that despite this, outsourcing will continue to be a problem for US workers in coming decades; new elements of traditional corporations like R&D may in fact be next on the outsourcing chopping block."
