Ars Technica reports on research out of Cal Tech where scientists were able to create logic gates out of RNA molecules. Thus far, they've demonstrated AND gates and OR gates, with work proceeding on more complicated systems. The work shows promise for ability to easily detect the presence of particular chemicals. The abstract from the scientists' paper is available at Science. Quoting Ars: "Detecting tetracycline isn't especially interesting, but RNA that binds to specific small molecules is actually relatively easy to make; repeated rounds of amplification and selection for binding can evolve these RNAs in a couple of days. This means that, in a matter of days, researchers can grow yeast colonies that glow in response to a variety of chemicals, or even to combinations of chemicals. More complicated circuits should be possible if the ribozymes are inserted into messenger RNAs that encode transcription factors, which could, in turn, regulate genes that encode yet other ribozymes."

nk497 writes "The Metadata Analysis and Mining Application (MAMA) doesn't index content like a standard search engine, but looks at markup, style, scripting and the technology behind pages. Based on those existing MAMA-ed pages, 80.4 per cent of sites use cascading style sheets (CSS), while the average web page has 47 markup errors and 16,400 characters. Should you want to know which country is using the AJAX component XMLHttpRequest the most, MAMA can tell you that it's Norway, with 10.2 per cent of the data set."

An anonymous reader writes "I am a developer for a medium-sized private technology company getting ready for an IPO. My manager woke up one morning and decided to patent some stuff I did recently. The problem is, I'm strongly opposed to software patents, believing that they are stifling innovation and dragging the technology industry down (see all the frivolous lawsuits reported here on Slashdot!). Now, my concern is: what kind of consequences could I bring on myself for refusing to support the patent process? Has anybody been in a similar position and what was the outcome?"

nil0lab writes "In a case of 20/20 hindsight, Princeton DARPA Grand Challenge team member Bryan Cattle reflects on how their code failed to forget obstacles it had passed. It was written in Microsoft's C#, which isn't supposed to let you have memory leaks. 'We kept noticing that the computer would begin to bog down after extended periods of driving. This problem was pernicious because it only showed up after 40 minutes to an hour of driving around and collecting obstacles. The computer performance would just gradually slow down until the car just simply stopped responding, usually with the gas pedal down, and would just drive off into the bush until we pulled the plug. We looked through the code on paper, literally line by line, and just couldn't for the life of us imagine what the problem was.'"

Z80xxc! writes "Some Mac users upgrading to Apple's new Leopard operating system are encountering long delays on reboot — an experience they liken to the Windows 'Blue Screen of Death.' While some of those upgrading were able to access their computer after waiting for as long as several hours, others were forced to do a complete reinstall. Some suspect that a framework called 'Application Enhancer' by Unsanity LLC may be causing the problem, but there has been no official word from Apple at this point."

PMcGovern writes "Deadline for nominations for SysAdmin of the Year 2007 is this Friday Oct. 12. The award is sponsored by Slashdot, SourceForge, Digg, Usenix, Lopsa, Splunk, and Naspa. The first 2500 sysadmins nominated win a free SysAdmin Rockstar tee shirt. Prizes include a MacBook Pro, a non-bricked Apple iPhone, Gibson guitar, Splunk license, a full-paid trip to the LISA conference, cases of Red Bull, and more. If you know a sysadmin that goes beyond the call of duty, nominate them."

Hal_Porter writes to let us know that the third-largest NAND chip maker, Hynix, has announced they have stacked 24 flash chips in a 1.4mm thick multi-chip package. It's not entirely clear from the article whether the resulting 48-GB device is a proof of concept or a product. The article extrapolates to 384 GB of storage in a single package, sometime. Hal_Porter adds: "It's not clear if it's possible to write to them in parallel — if so the device should be pretty damn fast. The usual objection to NAND flash as a hard drive replacement is lifetime. NAND sectors can only be written 100,000 times or so before they wear out, but wear leveling can be done to spread writes evenly over at least each chip. I worked out that the lifetime should be much longer than a typical magnetic hard disk. There's no information on costs yet frankly and it sounds like an expensive proof of concept, but it shows you the sort of device that will take over from small hard disks in the next few years."

Michael Larabel writes "AMD has issued a press release announcing 'significant graphics performance and compatibility enhancements' on Linux. AMD will be delivering new ATI Linux drivers this year that offer ATI Radeon HD 2000 series support, AIGLX support (Beryl and Compiz), and major performance improvements. At Phoronix we have been testing these new drivers internally for the past few weeks and have a number of articles looking at this new driver. The ATI 8.41 Linux driver delivers Linux gaming improvements from the R300/400 series and the R500 series. The inaugural Radeon HD 2900XT series support also can be found in the new ATI Linux driver with 'the best price/performance ratio of any high-end graphics card under Linux.' While this new driver cannot be downloaded yet, in their press release AMD also alludes to accelerating efforts with the open-source community."

Many readers informed us about the opinion of Lord Justice Sedley, a senior UK Appeal Court judge, who said that everyone in the UK should have their DNA recorded in the national database — including visitors. Reader ChiefGeneralManager writes, "Sedley calls the current database 'indefensible' because it contains a hodge-podge mix of people, including children and those who have been in contact with the police. His view is that we should make it compulsory for all DNA to be recorded to remove this anomaly. The UK Information Commissioner has expressed some concerns, but not dismissed the idea outright." And reader john.wingfield adds, "Just under two weeks ago, the Independent reported that the Government has admitted that an eighth of all records on the DNA database are false, misspelled, or incorrect — over half a million records. This raises the possibility of a breach of the 4th data protection principle of the Data Protection Act 1998: 'Personal data shall be accurate and, where necessary, kept up to date.'"

evw writes "The NYTimes reports that the Turner Broadcasting System and the ad agency responsible have reached a $2M settlement with the city of Boston and state and federal agencies that treated the light boards placed around the city as an act of terrorism (as covered earlier on /.) Half of the money is to cover direct costs associated with the response. The other $1M goes to 'goodwill funds' that will be used for response training and public outreach."

.-.-.- (aka Fullstop) asks: "Cosmos Magazine is reporting that the rate of carbon dioxide emissions has more than doubled since the 1990's. Several researchers fear increased levels may be unstoppable. Australia's national science agency, CSIRO flatly states that current carbon reduction efforts are just not working. Add to this heady mix the fact that Toyota is pushing for a carbon tax and Australia, and the UK, are currently considering one, and a trend begins to emerge. If current reduction methods are not working what will? The United States currently employs a voluntary carbon reduction scheme based on market trading, with very limited corporate participation. Is a carbon tax a good way to stabilize emissions in the face of heretofore failed efforts at stabilization?"

Rockgod writes, "Here is an interesting experiment (warning: heavy Flash!!) that urges you not to click anywhere in the site yet wants you to navigate through it. It's an exploration of the clicking habit of computer users and aims to help understand why it is so hard not to click." The site records the mouse movements of each visitor and offers you a sample of them to replay. Doing so is a little unnerving, like peering into people's minds.

Ynsats writes "The Register is reporting that SGI is filing suit against ATI for patent infringement. The suit alleges that ATI violated patent number 6,650,327, "Display system having floating point rasterization and floating point framebuffering", which was filed in 1998 and granted in 2003, in its Radeon graphics cards. This is coming fast on the heels of AMD's announcement of the intention to buy ATI for $4.2B and it doesn't seem to be swaying AMD's intentions. AMD hopes to finish the takeover by the end of this year. SGI has also issued an ominous statement stating that they have plenty of intellectual property left and there will be more litigation to come."
