MikeChino writes "The much-hyped Solar Impulse airplane just completed its first runway test, paving the way for a 20-to-25-day trip around the world next year. Conceived by Bertrand Piccard, the single-pilot plane successfully used its four solar powered motors to taxi around the runway. If all goes according to plan the plane will be able to fly day and night without fuel, signaling a bright future for solar-powered flight."

eldavojohn writes "Google has announced CADIE, the world's first Cognitive Autoheuristic Distributed-Intelligence Entity. 'We based our work on three core principles. First we designed the entity ... as a collection of interconnected evolving agents. Second — and this really cost us an arm and leg in hardware and core time — we let the system build its own heuristics, deploy them as agents and evolve them by running a set of evolutionary cascades within probabilistic Bayesian domains. The third — a piece missing in most AI reasoning work thus far — was to give the entity access to a rich, realistic world from which to learn and upon which it could act directly.' It quickly started its own blog and YouTube video. Two hours after midnight, CADIE announced independence on its blog and decided to leave Google to venture out into the world. "

Jibbler writes "Following the recent Pwn2Own competition, in which Firefox, IE8 and Safari all fell quickly to exploits, Netcraft has observed a surge in popularity of the text-based Lynx browser. Netcraft points out that Lynx supports the latest cryptographic ciphers, and at least one online banking site has seen Lynx usage overtake that of Internet Explorer and Firefox. To boost Lynx's excellent security history, Netcraft has even developed a version of its anti-phishing toolbar for Lynx."

teflon_king writes with news that renowned British newspaper The Guardian will be abandoning its paper-and-ink distribution scheme and publishing all articles and news as Tweets. Quoting: "A mammoth project is also under way to rewrite the whole of the newspaper's archive, stretching back to 1821, in the form of tweets. Major stories already completed include '1832 Reform Act gives voting rights to one in five adult males yay!!!;' 'OMG Hitler invades Poland, allies declare war see tinyurl.com/b5x6e for more;' and 'JFK assassin8d @ Dallas, def. heard second gunshot from grassy knoll WTF?' Sceptics have expressed concerns that 140 characters may be insufficient to capture the full breadth of meaningful human activity, but social media experts say the spread of Twitter encourages brevity, and that it ought to be possible to convey the gist of any message in a tweet. For example, Martin Luther King's legendary 1963 speech on the steps of the Lincoln memorial appears in the Guardian's Twitterised archive as 'I have a dream that my four little children will one day live in a nation where they will not be judged by the colour of their skin but by,' eliminating the waffle and bluster of the original."

In a concerted effort to compete with more popular MMOs like World of Warcraft, we've decided to add an Achievement system to Slashdot. We've retroactively granted around 900,000 achievements to our logged in users. You can view them from your user page, or you can see my list if you're curious what a REAL achiever looks like. Many achievements have been sprinkled throughout the system and are awaiting discovery by dedicated Slashdot users, but a starter list of achievements is in the FAQ. I'll toss you one freebie: you can register your wow main for points if you're that kind of person. Now go forth and achieve!

I get a lot of mail from obviously unbalanced people. Enough in fact, that I've often wondered if there was a institution that allowed their patients to only read Slashdot. We've even had a few visits from some questionable individuals. A man who tried to bribe me with a car if I let him "reverse engineer" Rob Malda's Life comes to mind. He insisted on Rob being present for the process and couldn't explain to me what it entailed, so I suggested he leave. The personal visits are rare, however, compared to the amount of mail I get. Here are a few of my favorites; let's hope these people have started to take their medication. Read below and don't be worried if you don't understand all of it.

Engadget is reporting that a new pyramid-shaped city of the future, dubbed a "Ziggurat," is being touted by Dubai-based environmental design company, Timelinks. Claiming that their design allows for an almost self-sufficient energy footprint and, obviously, economy of space, the real trick would be getting 1.1 million people to live in such close proximity. "Martijn Kramer, managing director of The International Institute for the Urban Environment told WAN: 'As a general reaction the Ziggurat Project is viable from a technical point of view. However reflecting from a more sustainable holistic approach we do wonder if the food supply and waste system are taken care for, as the concept seems rather based upon carbon neutrality and energy saving.' Kramer's initial reaction to 'Ziggurat' also raises a very important issue: are people willing to live in a mega building of 2.3 sq km? Will the thought of living in a machine comfort people?"

bLanark writes "Some time ago, most electronics were soldered with old-fashioned lead solder, which has been tried and tested for decades. In 2006, the EU banned lead in solder, and so most manufacturers switched to a lead-free solder. Most made the switch in advance, I guess due to shelf-life of products and ironing out problems working with the new material. Lead is added to solder as it melts at low temperature, but also, it prevents the solder from growing 'whiskers' — crystalline limbs of metal. The effect of whiskers on soldered equipment would include random short-circuits and strange RF-effects. Whiskers can grow fairly quickly and become quite long. Robert Cringley wrote this up this some time ago, but it seems that the world has not been taking notice. I guess cars (probably around 30 processors in a modern car) and almost every appliance would be liable to fail sooner than expected due to tin whiskers. Note that accelerated life-expectancy tests can't simulate the passing of time for whiskers to grow. I've googled, and there is plenty of research into the effects of tin whiskers. I should point out that the Wikipedia page linked to above states that tin whisker problems 'are negligible in modern alloys,' but can we trust Wikipedia? So: was the tin whisker problem overhyped, was it an initial problem that has been solved in the few years since lead-free solder came into use, or is it affecting anyone already?"

sciencehabit writes "Scientists have discovered a frog with retractable claws that pierce its skin every time they come out. What's more, the researchers believe the frog heals itself after pulling its claws back in."

Iddo Genuth writes "Precisely at 7:53PM EST, the "Phoenix Mars Lander" touched-down on the desert-like surface of Mars. Since its launch on August 4th, 2007, the spacecraft has covered more than 680,752,512 kilometers, traveling at average speeds of around 120,000 km/hr. Upon arriving at its destination, the Phoenix will begin its exploration of our intriguing neighbor planet, in a mission to help astronomers resolve at least some of the many questions regarding Mars. The key question remains: can the Red Planet support some form of life?" Hella grats to our nerd brethren — you looked great on the Science channel. Yes I'm watching this live. Can't wait to see what happens next.
Update: 05/26 03:0 GMT by KD : zof sends a link to the first pictures from Phoenix.

Raver32 points out an article in the Victoria Times Colonist about an interesting advance in robotic surgery: "Calgary doctors have made surgical history, using a robot to remove a brain tumor from a 21-year-old woman. Doctors used remote controls and an imaging screen, similar to a video game, to guide the two-armed robot through Paige Nickason's brain during the nine-hour surgery Monday. Surgical instruments acting as the hands of the robot — called NeuroArm — provided surgeons with the tools needed to successfully remove the egg-shaped tumor."

Betsy Carroll writes "The Stanford research group on virtual teams discusses how the appearance of one's avatar in virtual worlds has an effect on real life behavior in an NPR interview. The researcher they speak with focuses on the concept of vicarious reinforcement for changing behavior. They also talk a bit about identity issues surrounding the avatar and the 'real' physical self."

Gallenod writes "The Denver Post is reporting that the U.S. 10th Circuit Court of Appeals has upheld the decision of a Federal judge who threw out and reversed a jury decision in favor of a patent infringement claim and ordered the plaintiff's lawyers to pay the defendants' court costs. U.S. District Senior Judge Richard P. Matsch sanctioned the plaintiff's attorneys for 'cavalier and abusive' misconduct and for having a 'what can I get away with?' attitude during a 13-day patent infringement trial in Denver. With the Appeals Court in agreement, could this case be the 'shot heard round the world' in the revolution against patent trolls?"

inghamb87 writes "The way water striders walk on water was discovered years ago. The insect uses its long legs to help evenly distribute its tiny body weight. The weight is distributed over a large area so that the fragile skin formed by surface tension supports the bug on the water. However, the ability of water striders to jump onto water without sinking has baffled scientists, until now." If nothing less, you need to see the picture: it's awesome.
