Aberystwyth University researcher Stephen Pugh has developed a picture-taking robot designed to look for signs of life on Mars. Pugh is fine-tuning the robot’s onboard panoramic cameras and teaching it to point and shoot at features on the planet’s surface. “I have been looking in particular at how the robotic rover can point its camera at specific targets, such as rocks, without human intervention,” he says. The research’s long-term goal is to increase scientific data for all future planetary missions. “NASA has already found evidence of ice on Mars, but I don’t think rover will find evidence of anything more than water because if it was there I think we would have found it by now,” Pugh says. The researcher is developing software that will enable the robot to discover locations of interest more quickly and to choose targets for pictures by itself, without communicating with scientists on Earth.

Researchers remain optimistic about the prospect of keeping track of the exaflood of data, from gene sequences and distant pulsar signals to YouTube videos and email. During the recent annual meeting of the American Association for the Advancement of Science, one session gave scientists and other academics an opportunity to learn more about some current strategies for storing data and using it productively. University of California at San Diego professor Larry Smarr demonstrated how genetic sequences from ocean bacteria can be coupled with environmental information about the organisms. Smarr said researchers were able to target specific gene sequences, annotated with helpful information. Meanwhile, Google researcher Hal Varian said the company’s Google Insights for Search analytical tools used information on individual searches for Toyota automobiles to accurately predict its sales volume.

Queensland University of Technology (QUT) Ph.D. researcher Suriadi is investigating using an anonymous credential system, an Internet authentication system from the 1980s, to enable Web users to securely log in only once per Internet session. Suriadi says future single sign-on systems could give users access to multiple accounts–including email, bank, and shopping–but would need to provide extreme privacy to avoid hackers. He says the anonymous credential system could enhance the security and privacy of a single sign-on system. “The system works by revealing as little information about who you are as necessary for logging into an account, therefore allowing you to remain anonymous,” Suriadi says. A single sign-on system backed by the anonymous credential system requires the cooperation of business and organizations to enable it, Suriadi notes.
