Popular Android Applications Contain Security Flaws

Researchers from the University of California, Davis, discovered security flaws in roughly 120,000 free applications for the Android smartphone, including several popular texting, messaging, and microblogging programs. These vulnerabilities could be exploited by malware that could then allow the hackers to access users’ private information or post fraudulent messages using social media. The UC Davis researchers found developers of these applications didn’t secure parts of the code. In the WeChat service, for example, they were able to malicious code to turn off the WeChat background service such that a user would think the service is continuing to work when it is not. They have notified the developers concerning the flaws they found.(EurekAlert)(University of California Davis)
 

UC Davis Start-Up Uses Silicon to Provide a Cheap Shave

A recently launched University of California, Davis start-up plans to use semiconductor-manufacturing technology to provide sharp, low-cost razor blades. Nano-Sharp Inc., which UC Davis researchers founded, plans to use silicon wafers that will enable them to make razor blades and surgical tools far more inexpensively than companies can manufacture conventional silicon or ceramic blades; however, they have not said precisely what it is about this process that makes the blades more affordable to manufacture. The process is being patented. The researchers stumbled across their approach while etching silicon wafers to be used as solar cells. The UC Davis technique creates blades across the surface of the wafer, where conventional methods create the blade by sharpening the edge of a silicon wafer. This new approach yields a sharpness close to that of diamond blades. The researchers say they could improve these blades’ performance by applying various semiconductor technologies. The University of California system recently gave them money so that they can develop a prototype to attract private investors.
