Security: Computer scientists develop tool to make the Internet of Things safer Posted: 02 Jun 2014 12:59 PM PDT Computer scientists have developed a tool that allows hardware designers and system builders to test security -- a first for the field. There is a big push to create the so-called Internet of Things, where all devices are connected and communicate with one another. As a result, embedded systems -- small computer systems built around microcontrollers -- are becoming more common. But they remain vulnerable to security breaches. Some examples of devices that may be hackable: medical devices, cars, cell phones and smart grid technology.

Electrical response of metals to extreme pressures predicted Posted: 02 Jun 2014 12:57 PM PDT New research makes it possible to predict how subjecting metals to severe pressure can lower their electrical resistance, a finding that could have applications in computer chips and other materials that could benefit from specific electrical resistance.

Researchers propose tactics for ethical use of Twitter data Posted: 02 Jun 2014 08:56 AM PDT Tweets are only 140 characters, but amass enough of them, and researchers can deduce a great deal about subjects ranging from disease outbreaks to social unrest. Researchers have proposed guidelines to make sure data mined from Twitter data is obtained and used ethically.
