Matt_dk writes "Spectacular satellite images suggest that Mars was warm enough to sustain lakes three billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in the journal Geology. Earlier research had suggested that Mars had a warm and wet early history but that between 4 billion and 3.8 billion years ago, before the Hesperian Epoch, the planet lost most of its atmosphere and became cold and dry. In the new study, the researchers analysed detailed images from NASA’s Mars Reconnaissance Orbiter, which is currently circling the red planet, and concluded that there were later episodes where Mars experienced warm and wet periods."

Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

suraj.sun alerts us to an anonymous-source story up at the NY Post, not what we would normally consider a leading source of tech news, claiming that Microsoft's introduction of Bing has alarmed Google. "...co-founder Sergey Brin is so rattled by the launch of Microsoft's rival search engine that he has assembled a team of top engineers to work on urgent upgrades to his Web service, The Post has learned. Brin, according to sources..., is himself leading the team of search-engine specialists in an effort to determine how Bing's crucial search algorithm differs from that used by [Google]. 'New search engines have come and gone in the past 10 years, but Bing seems to be of particular interest to Sergey,' said one insider, who spoke on the condition of anonymity. The move by Brin is unusual, as it is rare these days for the Google founders to have such hands-on involvement in day-to-day operations at the company, the source added." CNet's coverage of the rumor begins with the NY Post and adds in Search Engine Land's speculation on what the world of search would look like if Yahoo exited the field.
