The Wall Street Journal has a look at global warming research using rubber duckies. The toys have been employed in tracking ocean currents since 1992; but recently NASA robotics expert Alberto Behar released 90 yellow rubber ducks into the melt water flowing down a chasm in a Greenland glacier. "Each duck was imprinted with an email address and, in three languages, the offer of a reward. If all goes well, Dr. Behar hopes that one day they will emerge 30 miles or so away at the glacier's edge in the open water of Disko Bay near Ilulissat, bobbing brightly amid the icebergs north of the Arctic Circle, each one a significant clue to just how warming temperatures may speed the glacier's slide to the sea."

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.'"

ChazeFroy writes "A new study estimates that the AIDS virus, HIV, started to circulate in the human population between 1884 and 1924, with a more focused estimate at 1908. This is much earlier than the previously-held estimate of 1930. 'The new result is "not a monumental shift, but it means the virus was circulating under our radar even longer than we knew," says Michael Worobey of the University of Arizona, an author of the new work.' The article also speculates that HIV first began to spread in Kinshasa, Congo."

DragonFire1024 lets us know that Wikileaks has obtained 10 years of messages and interviews by Osama bin Laden, the leader of al-Qaeda. The documents were translated and the messages and interviews were authenticated by the US CIA. "The nearly three hundred page, 'official use only' packet from 2004, translated by the Foreign Broadcast Information Service, a division of the CIA, includes interviews with bin Laden from various news agencies and also includes messages he sent directly to the US from the periods of 1994 to 2004. One message includes bin Laden's denial of having anything to do with the September 11, 2001 attacks in New York City, Washington DC, and Pennsylvania."

After the first announcement on 1997-04-27 and over eleven years of fresh start after fresh start, Duke Nukem Forever finally comes to your system. At least if your system is an Xbox 360. Jon Siegler, the webmaster of 3D Realms, confirms this on their site: "As has been reported around the net today, we can confirm that the game has indeed passed final certification with Microsoft on Friday the 15th of August (on our first try, no less). That means the game is done — it is now in the hands of Microsoft." Update: 08/19 10:47 GMT by T : Several readers have written with a correction: this announcement is actually about Duke Nukem 3D, rather than Duke Nukem Forever.

mikek2 writes "When retired Philadelphia-area doctor and Vietnam veteran Dr. Herman I. Libshitz went to upgrade his dial-up connection to Verizon DSL, he was informed they wouldn't complete the order because his last name contained an expletive. Repeated calls to several levels of management at Verizon failed to resolve the problem, with several managers suggesting he change his last name. It all worked out in the end, after the Philadelphia Enquirer intervened."

Multiple readers have written to tell us of news that Pakistan has ordered its ISPs to block access to YouTube "for containing blasphemous web content/movies." This follows increasing unrest in Pakistan over a Danish newspaper's reprinting of cartoons which depict Islam in a less-than-favorable light. The cartoons also sparked controversy when they were first published a few years ago.

XueCast writes "A few days ago, the New York Police Department, one of the largest police forces in the US, announced that they are planning to make New York greener by replacing their gasoline motorcycle fleet with the super-quiet and energy efficient electric scooters from Vectrix. NYPD said that they will first road test four electric scooters from the Rhode Island-based electric vehicle manufacturer next month, and if the road test is a success, NYPD said that they plan to order more electric scooters from Vectrix to replace their less-than-green motorcycle fleet."

Multiple users have written to tell us of an LA Times report that an asteroid may hit Mars on January 30th. The asteroid is roughly 160 feet across, and JPL-based researchers say that it will have a 1-in-75 chance of striking Mars. Those odds are very high for this type of event, and scientists are hoping to witness an impact of a similar scope to the Tunguska disaster. From the LA Times: "Because scientists have never observed an asteroid impact -- the closest thing being the 1994 collision of comet Shoemaker-Levy with Jupiter -- such a collision on Mars would produce a 'scientific bonanza,' Chesley said."
