Stem Cell Fraudster May Have Actually Made Breakthrough. Otter writes "Woo Suk Hwang's career swung from fame over his lab's claim of the first stem cells from a cloned human embryo to humiliation when the results were found to be fake. Research at Harvard on Hwang's cells has found that they are actually parthenogenic lines derived from eggs -- perhaps a more important and difficult achievement than what he had been claiming! 'Researchers said that the distinct "genetic fingerprint" of the stem cells means they may be the first in the world to be extracted from embryos produced by the so-called "virgin birth" method, or parthenogenesis. This happens when eggs are stimulated into becoming embryos without ever being fertilised by sperm, and has been achieved in animals. However, before Hwang, no one had managed to produce a human embryo using parthenogenesis which lived long enough to allow the extraction of viable stem cells.'"Read more of this story at Slashdot.

Forensic Analysis Reveals Al-Qaeda's Image Doctoring. WerewolfOfVulcan writes "Wired reports that researcher Neal Krawetz revealed some very interesting things about the Al-Qaeda images broadcast in the mass media. Analysis shows that they're heavily manipulated, a discussion meant to illustrate a new technique that can spot forgery in digital media. 'Krawetz was ... 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 ... 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.'"Read more of this story at Slashdot.

Point-and-Click Gmail Hacking Shown at Black Hat. not5150 writes "Using Gmail or most other webmail programs over an unsecured access points just got a bit more dangerous. At Black Hat Robert Graham, CEO of errata security, showed how to capture and clone session cookies very quickly over connections without encryption. He even hijacked a shocked attendee's Gmail account in the middle of his presentation. 'While Ou was typing, Graham was running Ferret and sniffing all the cookies that were being sent from Ou's laptop and Google. Graham then clicked on Ou's IP address and Gmail page, complete with Ou's recently sent message on the screen. We photographed both Graham's and Ou's laptop at that time and posted it to the picture gallery. You'll see that the contents are exactly the same.'"Read more of this story at Slashdot.
