New Advance Confines GMOs To the Lab Instead of Living In the Wild

Thu, 22/01/2015 - 8:22pm
BarbaraHudson (3785311) writes In Jurassic Park, scientists tweak dinosaur DNA so that the dinosaurs were lysine-deficient in order to keep them from spreading in the wild. Scientists have taken this one step further as a way to keep genetically modified E. coli from surviving outside the lab. In modifying the bacteria's DNA to thwart escape, two teams altered the genetic code to require amino acids not found in nature. One team modified the genes that coded for proteins crucial to cell functions so that that produced proteins required the presence of the synthetic amino acid in the protein itself. The other team focused on 22 genes deemed essential to a bacterial cell's functions and tied the genes' expression to the presence of synthetic amino acids. For the bacteria to survive, these synthetic amino acids had to be present in the medium on which the bacteria fed. In both cases, the number of escapees was so small as to be undetectable."

Fujitsu Psychology Tool Profiles Users At Risk of Cyberattacks

Thu, 22/01/2015 - 7:11pm
itwbennett writes Fujitsu Laboratories is developing an enterprise tool that can identify and advise people who are more vulnerable to cyberattacks, based on certain traits. For example, the researchers found that users who are more comfortable taking risks are also more susceptible to virus infections, while those who are confident of their computer knowledge were at greater risk for data leaks. Rather than being like an antivirus program, the software is more like "an action log analysis than looks into the potential risks of a user," said a spokesman for the lab. "It judges risk based on human behavior and then assigns a security countermeasure for a given user."

Silk Road Journal Found On Ulbricht's Laptop: "Everyone Knows Too Much"

Thu, 22/01/2015 - 6:30pm
sarahnaomi writes On Wednesday, prosecutors in the Silk Road trial began to lay out the wealth of evidence found on the laptop taken from accused kingpin Ross Ulbricht in a San Francisco library in October 2013. The evidence presented by prosecutor Timothy Howard was the most comprehensive and damning thus far, including more than a thousand pages of chats between the site's pseudonymous operator Dread Pirate Roberts and Silk Road administrators. Also entered into evidence was a journal that dates back to at least 2010 describing the creation and operation of the site. FBI computer scientist Thomas Kiernan, the second witness in the trial, testified about the day Ulbricht was arrested and the evidence gathered from his laptop.
