"DNA Origami" Could Allow For Controlled Drug Delivery 29

esinclair writes "As reported in Nature News, researchers have designed a method which allows DNA strands to be formed into cubes and other designs by oligonucleotides. The uses of this DNA origami are still being developed. One possibility for them is to be used as a drug-delivery system. The fact that scientists have also come up with a method to lock these structures and use 'keys' to unlock them would conceivably allow for a controlled delivery system."

Columnist Fired For Reviewing Pirated Movie 466

Hugh Pickens writes "Roger Friedman, an entertainment columnist for FoxNews.com, discovered over the weekend just what Rupert Murdoch means by 'zero tolerance' when it comes to movie piracy. On Friday, the film studio 20th Century Fox — owned by the News Corporation, the media conglomerate ruled by Mr. Murdoch — became angry after reading Friedman's latest column, a review of 'X-Men Origins: Wolverine,' a big-budget movie that was leaked in unfinished form on the Web last week. Friedman posted a mini-review, adding, 'It took really less than seconds to start playing it all right onto my computer.' The film studio, which enlisted the FBI to hunt the pirate, put out a statement calling Friedman's column 'reprehensible' while News Corporation weighed in with its own statement, saying it had asked Fox News to remove the column from its Web site. 'When we advised Fox News of the facts,' the statement said, 'they promptly terminated Mr. Friedman.'"

Ubuntu Download Speeds Beat Windows XP's 515

narramissic writes "Doing a download speed test of his Time Warner cable connection, James Gaskin discovered something odd, something that he is quick to note isn't a rigorous benchmarked lab test. The discovery: His Ubuntu machine 'returned a rating from the Bandwidth.com test of 22-25mbps over several tests' while the same test done from a Windows XP PC returned a rating of 12-14mbps. The two computers used in the test are 'almost identical: both off-lease Compaq small form factor D515s, part of the very popular corporate desktop D500 family. Both have Pentium 4 processors running at 2GHz. The Ubuntu machine has 768MB of RAM, while the XP box has only 512MB of RAM. Both run Firefox 3 as their browser.' Gaskin's question: Can a little extra RAM make that much difference in Internet download speeds or does Ubuntu handles networking that much faster than Windows XP?"
