Regenerating a whole tooth is no less complicated than rebuilding a whole heart, says Songtao Shi of the University of Southern California, who heads a team working on creating such a tooth. Not only do you have to create smart tissue (nerves), strong tissue (ligaments) and soft tissue (pulp), you’ve got to build enamel — by far the hardest structural element in the body. And you have to have openings for blood vessels and nerves. And you have to make the whole thing stick together. And you have to anchor it in bone. And then you have to make the entire arrangement last a lifetime in the juicy stew of bacteria that is your mouth. It’s a nuisance, but researchers are closing in on it. In fact, they think the tooth will probably be the first complex organ to be completely regenerated from stem cells. In part this is because teeth are easily accessible — say ahhhhh. So are adult stem cells, found abundantly in both wisdom and baby teeth — no embryos required, and your immune system won’t reject your own cells
Looks like Bill is about to launch is mission to inflict himself on an unsuspecting ex-X-Files director:
Before, I run
half-cockedout to California seekingKim Manners(One of the Directors ofThe X Files) I would like to know if such a ventureout Westtorev-upthe formerthirteen productionslocation ? I am not only an unregistered fan bummed out, as thousands happen to be; I am trying to facilitate the energy towards some worthwhile end! Honestly, the epidode invilving the Birth of William holds so much! To think that The Wonderful Actors, Jillian Anderson and David Duchovny, ARE A MUST is nonsense…Lucky for Chris Carter et al. They gave his series a wonderful start; but the plot and the writing skills deserve so much more! Please respond!
Okay, so he’s dropped plans to harass Chris Carter and has switched target to Kim Manners. Who knows why?
He’s an unregistered fan
? I don’t even know what that means. He likely should be registered as menace and his whereabouts broadcast so any of his intended victims can get out of his flight path or have warning to release the guard dogs.
Aside from still being unable to deal with the series having ended years ago, he’s obsessed with a rather lame subplot and wishes to carry it on under his own steam without the show’s two main stars. Somehow he seems to have missed a major clue here. The show worked due the chemistry of Anderson and Duchovny and the brilliant writing and directing of a small core of talented people.
Bill is under the impression that he can set all that aside all of the things that made the show work so well, throw together his own screenplay and hand it to a director who will likely see him escorted off the premises if he manages to get close enough to had it over.
I’d be quite happy if somebody could round up Bill with a butterfly net and get him back on his meds, because I do not get why he insists on getting my approval for his delusions.
I yam what I yam,
declared Popeye. And just what that is is likely to become less clear as the copyright expires on the character who generates about £1.5 billion in annual sales. From 1 January, the iconic sailor falls into the public domain in Britain under an EU law that restricts the rights of authors to 70 years after their death. Elzie Segar, the Illinois artist who created Popeye, his love interest Olive Oyl and nemesis Bluto, died in 1938
Online encyclopedia Wikipedia said last week that it had attained its fundraising goal of $US6 million, enough to cover operating expenses for the current fiscal year.

A new trojan popped up at several torrent sites a few weeks ago, one that blocks access to The Pirate Bay and Mininova, while informing its victims that downloading is wrong
. The trojan edits the hosts file on Windows machines, and redirects the BitTorrent sites to localhost, making them impossible to load
2009 has got off to a great start for a team of iPhone enthusiasts with little regard for Apple’s licensing requirements. They’ve finally figured out a way to get the phone to work with any mobile phone carrier
A blogger from India recently wrote a piece about the new surveillance laws of India and the arguments used to pass it as well as some of the provisions that were mentioned seemed surprisingly similar to that of laws being brought forth to legislators in countries like Australia, Britain and what is currently being talked about in the United States
Taking a page out of Apple’s book, Google is now urging Gmail users to drop Internet Explorer 6 (IE6) in favour of Firefox or Chrome that, according to the company, run the popular web-based email service twice as fast
. Google also labels IE6 as an unsupported browser, meaning it fails to run some Gmail features
A robot radiotherapy machine to treat cancer is to be available in the UK for the first time from February. Called the Cyberknife, it moves with a patient’s breathing so tumours can be targeted with greater accuracy, and damage to healthy tissue is reduced
Faulty software has crippled 30GB first generation versions of the Microsoft Zune digital media player, affecting thousands of customers worldwide. The company said it was aware of the problem, and offered advice to Zune users on how to solve it. Customers have reported that their devices refuse to boot up, and freeze when the start-screen appears. The Zune was launched in 2006 as Microsoft’s contender to Apple’s highly successful iPod player
The second month of Microsoft’s campaign against fake security software has resulted in the removal of the rogue Antivirus 2009
application from almost 400,000 infected PCs. Microsoft claims that December’s version of the Malicious Software Removal Tool — the free utility included in Windows Update every month — specifically targeted Antivirus 2009
. According to Microsoft, MSRT removed the rogue application from over 394,000 PCs in the first nine days after it was released on 9 December

Kevin Martin, Chairman of the FCC, has dropped the content filtering provisions from the proposal for free wireless broadband service, according to an interview with Ars Technica. Previous drafts of the plan required protection methods to prevent users from accessing objectionable content such as pornography
The FBI today challenged anyone in the online community to break a cipher code on its site. The code was created by FBI cryptanalysts. The bureau invited hackers to a similar code-cracking challenge last year and got tens of thousands of responses it said
Schools have installed CCTV cameras and microphones in classrooms to watch and listen to pupils as young as four. The Big Brother-style surveillance is being marketed as a way to identify pupils disrupting lessons when teachers’ backs are turned. But data protection watchdog the Information Commissioner has warned the surveillance may be illegal and demanded to know why primary and secondary schools are using this kind of sophisticated equipment to watch children
The prevalence of American-made goods in Iran has led US officials to crack down on the cottage industry of smugglers in nearby Dubai who purchase everything from iPhones to Bratz dolls to sell in Iran. But the biggest share of HP printers, among the most visible of US goods here, come not through smugglers, but through a series of international transactions that enable HP to sidestep US sanctions
The Internet needs to be globally regulated if it is to have any chance of stopping scams such as security scareware
, a researcher has suggested. According to Mary Landesman of ScanSafe, the recent Federal Trade Commission (FTC) injunctions against two companies accused of distributing fake anti-virus programs is a step in the right direction but against a backdrop of widespread abuse
Random numbers — numbers without any pattern — are vital to many applications, such as computer simulations, statistics, and cryptography. There are many ways to generate them using unpredictable physical processes, including electric-signal noise and radioactive decay, but these methods cannot produce the quantities of numbers needed to keep up with the high data-processing rates of today’s computers. A group of scientists seems to have discovered a way around this problem. They have found that the physical chaos present in semiconductor lasers — laser light produced using a semiconductor as the medium — can produce good-quality random number sequences at very high rates
