We see the popular "captcha" security mechanism often ― wavy letters websites ask us to type into a box. It's used by web pages and newsletter sign-up forms to prevent computer robots from hacking into servers and databases. But these codes, which are becoming increasingly complicated for an average person to use, are not immune to security holes. http://www.physorg.com/news181311669.html Technology Tue, 29 Dec 2009 12:21:43 EST news181311669 The sight of a cockroach scurrying for cover may be nauseating, but the insect is also a biological and engineering marvel, and is providing researchers at Oregon State University with what they call "bioinspiration" in a quest to build the world's first legged robot that is capable of running effortlessly over rough terrain. http://www.physorg.com/news181237551.html Electronics Mon, 28 Dec 2009 15:49:21 EST news181237551 Japanese researchers said Monday they had developed a "hummingbird robot" that can flutter around freely in mid-air with rapid wing movements. http://www.physorg.com/news181208607.html Electronics Mon, 28 Dec 2009 07:44:26 EST news181208607 The sea was heaving, the skies gray.
