Quantum computing taps nucleus of single atom Apr 17th 2013, 17:18 Australian engineers have demonstrated that quantum information can be "written" onto the nucleus of a single atom and "read" out with incredible accuracy. The result was achieved using a silicon chip that can be wired up and operated electronically. | A new twist for quantum systems Apr 17th 2013, 17:18 Physicists have developed a method for precisely controlling quantum systems by exploiting a trick that helps cats to land on their feet and motorists to fit their cars into parking spots. In the longer run, the method could lead to the development of more reliable quantum computers. | Security holes in smartphone apps Apr 17th 2013, 13:19 Popular texting, messaging and microblog apps developed for the Android smartphone have security flaws that could expose private information or allow forged fraudulent messages to be posted, according to researchers. | Scientists pinpoint brain's area for numeral recognition Apr 16th 2013, 22:00 Scientists have determined the precise anatomical coordinates of a brain "hot spot," measuring only about one-fifth of an inch across, that is preferentially activated when people view the ordinary numerals we learn early on in elementary school, like "6" or "38." | Information technology amplifies irrational group behavior Apr 11th 2013, 16:40 Web tools and social media are our key sources of information when we make decisions as citizens and consumers. But these information technologies can mislead us by magnifying social processes that distort facts and make us act contrary to our own interests. Companies such as Google and Facebook have designed algorithms that are intended to filter away irrelevant information -- known as information selection -- so that we are only served content that fits our clicking history. Researchers say this is, from a democratic perspective, a problem as you may never in your online life encounter views or arguments that contradict your worldview. | |
