Feed Science Daily: New Telomere Discovery Could Help Explain Why Cancer Cells Never Stop Dividing (sciencedaily.com)

From feed by sdfeed
Scientists have discovered that telomeres, the repeated DNA-protein complexes at the end of chromosomes that progressively shorten every time a cell divides, also contain RNA. This discovery calls into question our understanding of how telomeres function, and may provide a new avenue of attack for stopping telomere renewal in cancer cells.

Feed Engadget: Sony's Cyber-shot T200 gets its first review (engadget.com)

You may remember Sony's new Cyber-shot T200 from way back at IFA, where we had the great and terrible pleasure of getting our grubby mitts all over it. Well, CNET Asia has gotten their mitts on the device for a thorough review, and we thought we'd bring you the many, many highlights. Overall, they seem to like the design, but aren't crazy about the loss of some buttons, which they say makes the camera feel a little cramped, though the large, 3.5-inch touchscreen display makes up for it. The camera's smile detection -- which is one of its more novel features -- is reported to be inaccurate and touchy, and the speed of startup and first shot on the T200 apparently leaves something to be desired. CNET says that the camera's image quality is "decent," but that they detected noise at ISO 400, and anything past ISO 800 was a nasty mess. Overall, they're not in love, but they do seem to be feeling a strong "like." Browse on over and catch the whole review.

Submission + - PEBKAC Still Plagues PC Security (arstechnica.com)

Billosaur writes: "ARS Technica is reporting on a study release by McAfee and the National Cyber Security Alliance (as part of the beginning of National Cyber Security Awareness Month) that suggests when it comes to PC security, the problem between the keyboard and the chair is even worse. PEBKAC has always been a problem, but the study highlights just how prevalent it has become. 87 percent of the users contacted said they used anti-virus software, while 70 percent use anti-spyware software. Fewer (64 percent) reported having their firewalls turned on, and only 27 percent use software designed to stop phishing attempts. Researchers were allowed to scan the computers of a subset of the users, and while 70 percent claimed to be using anti-spyware software, only 55 percent of the machines of those users scanned showed evidence of the software."

German law prohibits storing personal data for a longer time — if not needed for accounting. German privacy activists have started a campaign Wir speichern nicht, ("we don't log your data!") which provides manuals how to turn off the IP logging on your server."

Submission + - Many antivirus tools fail in LinuxWorld test (darkreading.com)

Only three of the products caught all of the viruses; three only caught 61 percent, and one caught an abysmal 6 percent. The test, which wasn't particularly complicated, proves that there still are wide differences in the effectiveness of AV tools. A lot of people think all AV tools are the same — they're not! http://www.darkreading.com/document.asp?doc_id=131 246&WT.svl=news1_1"

Submission + - Forensics Expert says Al-Qaeda Images Altered

Submitted by WerewolfOfVulcan
WerewolfOfVulcan writes: Wired reports that researcher Neal Krawetz revealed some veeeeeery interesting things about the Al-Qaeda images that our government loves to show off.

From the article: "Krawetz was also able to determine that the writing on the banner behind al-Zawahiri's head was added to the image afterward. In the second picture above showing the results of the error level analysis, the light clusters on the image indicate areas of the image that were added or changed. The subtitles and logos in the upper right and lower left corners (IntelCenter is an organization that monitors terrorist activity and As-Sahab is the video production branch of al Qaeda) were all added at the same time, while the banner writing was added at a different time, likely around the same time that al-Zawahiri was added, Krawetz says." Why would Al-Qaeda add an IntelCenter logo to their video? Why would IntelCenter add an Al-Qaeda logo? Methinks we have bigger fish to fry than Gonzo and his fired attorneys... }:-) The article contains links to Krawetz's presentation and the source code he used to analyze the photos.
