The scientists showed how manipulation of circadian rhythms caused cabbage to produce more phytochemicals, including antioxidants.

App to protect private data on iOS devices finds almost half of other apps access private data Posted: 20 Jun 2013 07:12 AM PDT Almost half of the mobile apps running on Apple's iOS operating system access the unique identifier of the devices where they're downloaded, computer scientists have found. In addition, more than 13 percent access the devices' location and more than 6 percent the address book.
