holy_calamity writes "Although flash memory that stores each bit on a single nanotube has been tinkered with in the lab for years, it has always been much slower than the devices in use today. A Finnish team has now cracked that, demonstrating single bits of nanotube memory that can be written in just 100 nanoseconds. Existing flash memory takes tens of microseconds."

SUNSTOP writes to tell us that a relatively unknown Maryland scientist has proposed a public patent that he claims could combat global warming. The proposed plan would require massive amounts of water to be sprayed into the air in an effort to bolster the earth's existing air conditioning system. "First, the sprayed droplets would transform to water vapor, a change that absorbs thermal energy near ground level; then the rising vapor would condense into sunlight-reflecting clouds and cooling rain, releasing much of the stored energy into space in the form of infrared radiation. Kenneth Caldeira, a climate scientist for the Carnegie Institution's Department of Global Ecology at Stanford University whose computer simulation of Ace's invention suggests it would significantly cool the planet. The simulated evaporation of about one-half inch of additional water everywhere in the world produced immediate planetary cooling effects that were projected to reach nearly 1 degree Fahrenheit within 20 or 30 years, Caldeira said."

In just a few days, some of us will be making the trek to this year's Blizzcon event in Anaheim, CA. In addition to the interesting announcements, sneak peeks, and other distractions, we will be sitting down with several Blizzard employees to answer any questions you might have. So far we have scheduled some time with Chris Sigaty, lead producer on StarCraft II; Jeffrey Kaplan (aka Tigole), game director for World of Warcraft; Leonard Boyarsky, lead world designer on Diablo III; and Paul Sams, Blizzard COO. Please address your questions to one (or several) of these candidates and try to keep them civil and on topic. Questions about Diablo III's art style will most likely be omitted since we have limited time and that dead horse has already been beaten into submission. The usual Slashdot interview rules apply, but beyond that, the sky is the limit.

coondoggie writes to tell us that DARPA seems to still be having fun with their funding and continues to aim for the "far out." The latest program, a submersible airplane, seems to have been pulled directly from science fiction. Hopefully this voyage to the bottom of the sea is of the non-permanent variety. "According to DARPA: 'The difficulty with developing such a craft come from the diametrically opposed requirements that exist for an airplane and a submarine. While the primary goal for airplane designers is to try and minimize weight, a submarine must be extremely heavy in order to submerge underwater. In addition, the flow conditions and the systems designed to control a submarine and an airplane are radically different, due to the order of magnitude difference in the densities of air and water.'"

An anonymous reader writes "Stanford computer scientists have developed an artificial intelligence system that enables robotic helicopters to teach themselves to fly difficult stunts by 'watching' other helicopters perform the same maneuvers. The result is an autonomous helicopter that can perform a complete airshow of complex tricks on its own. The stunts are 'by far the most difficult aerobatic maneuvers flown by any computer controlled helicopter,' said Andrew Ng, the professor directing the research of graduate students Pieter Abbeel, Adam Coates, Timothy Hunter and Morgan Quigley. The dazzling airshow is an important demonstration of 'apprenticeship learning,' in which robots learn by observing an expert, rather than by having software engineers peck away at their keyboards in an attempt to write instructions from scratch.'" The title of the linked article uses the term "autonomous," but that's somewhat misleading. The copters can't fly on their own, but rather can duplicate complex maneuvers learned from a human pilot.

Last month, Turbine's Lord of the Rings Online: Shadows of Angmar went live in what was arguably the most well-received launch for a Massively Multiplayer game since World of Warcraft. The game soared to the top of the retail charts, and has been a breath of fresh air for gamers looking to get a taste of something just a little bit different and a little bit hobbity. Today, you have the chance to ask Turbine's CEO Jeff Anderson questions about the process of creating the game, the Tolkien license, and new content we'll see in Middle Earth in the coming weeks and months. One question per comment, please. We'll take the best of the lot and put them to Mr. Anderson in a phone interview later this week. We'll post his responses as soon as we can, so make sure to get your question in today if you want it to show up in his response.

Tamas Feher from Hungary writes "An Italian archaeologist accidentally found that the central gem in Tutankhamun's regal necklace is not amber, but a mere piece of yellow glass. Kinda cheap for the famous Egyptian pharaoh, best known for his splendid golden mask. Except that piece of glass is much older than civilization. Where did it come from, StarGate? Kind of. Scientists now think a meteorite much larger than the Tunguska event fell from the sky and exploded over the Sahara in prehistoric times. The tremendous heat of the 1000 A-bomb sized fireball melted large chunks of desert sand into perfect glass. The memory of such an apocalyptic event may have made sand-glass gems a desirable symbol, meant to emphasize the pharaoh's heavenly powers."

devv_null asks: "This morning on my drive to work, I was listening to the latest podcast of the Philosophers Zone. The topic of the program was 'Is a free market in ideas a good idea?'. It featured author and speaker Jaron Lanier, who in May published an article Digital Maoism. He highlighted Wikipedia as an example of the one of the worst kinds of 'collective intelligence' and using the 'wisdom of the crowd' to average facts about the world and include them in a massive, lifeless document. Being a habitual Wikipedia user, I could only disagree with his take on the web enterprise. While it shouldn't be considered the ultimate source of knowledge on the web, I think it's ideal in many cases to use as a starting point. Apparently, Lanier thinks a Google search results page is better." So, what is your take on this issue?

janus zeal writes "A form of solid carbon dioxide that could be used to make ultra-hard glass or coatings for microelectronic devices has been discovered. The material, named amorphous carbonia, was created by scientists from the University of Florence in Italy. Writing in the journal Nature, the team says the material was theoretically possible but had never been created. It was made by squeezing dry ice, a form of carbon dioxide used to create smoke in stage shows, at huge pressure. Scientists are interested in the new material because of the potential applications. Also, they believe it could give them clues to the processes that happen in the center of huge gas giant planets such as Jupiter."

mikemuch writes "Use that graphics card for something besides games. ExtremeTech has a group review of three browsers that use some aspect of 3D to display the Web. While none of them are going to put Firefox or IE out of business any time soon, they're fun to play with and give a new slant to the Web." From the article: "Whatever happened to the virtual reality, 3D world of the Web? Back in the late '90s, all the hype was about VRML -- Virtual Reality Markup Language -- which would turn the web into an immersive environment that you'd maneuver around to get to the information you wanted. We're here to tell you that the reports of the 3D Web's death are greatly exaggerated."

AriaStar asks: "It's overwhelming to start trying to learn all the different technologies needed to go into programming. It seems that every type of technology assumes knowledge of a different one, which in turn requires knowledge of another, until it's gone full circle. I am interested in everything from Unix to AJAX to Perl. Things like HTML, Javascript, and SQL are like English, but then again, they're basic. Where is the best place to start? What is a good path for someone who learns quickly and easily, but who is simply too overwhelmed, to take?"
