zootropole alerts us to a press release issued today by Lawrence Livermore National Laboratory, announcing the production of 'billions of particles of anti-matter.' "Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma 'jet.' This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts." The press release doesn't characterize the laser used in this experiment, but it may have been this one.

Hugh Pickens writes "Discover magazine has an interesting article on the multiverse theory — a synthesis of string theory and the anthropic principle that explains why our universe seems perfectly tailored for life without invoking an intelligent creator. Our universe may be but one of perhaps infinitely many universes in an inconceivably vast multiverse. While most of those universes are barren, some, like ours, have conditions suitable for life. The idea that the universe was made just for us — known as the anthropic principle — debuted in 1973 when Brandon Carter proposed that a purely random assortment of laws would have left the universe dead and dark, and that life limits the values that physical constants can have. The anthropic principle languished on the fringes of science for years, but in 2000, new theoretical work threatened to unravel string theory when researchers calculated that the basic equations of string theory have an astronomical number of different possible solutions, perhaps as many as 101,000, with each solution representing a unique way to describe the universe. The latest iteration of string theory provides a natural explanation for the anthropic principle. If there are vast numbers of other universes, all with different properties, at least one of them ought to have the right combination of conditions to bring forth stars, planets, and living things." So far xkcd is simulating just one single universe.

The much-anticipated second expansion to World of Warcraft, entitled Wrath of the Lich King, launched on Thursday, introducing a new continent, raising the level cap to 80, and bringing a wealth of new items, spells, dungeons, and monsters to the popular MMO. Crowds gathered and lines formed outside stores around the world leading up to the release. Massively has put together a series of articles for players wishing to familiarize themselves with the expansion, and CVG has a piece discussing the basics as well. It didn't take long for the first person to reach level 80; a French player called "Nymh" reached the level cap on his Warlock only 27 hours after the expansion went live. Not to be outdone, a guild named "TwentyFifthNovember" managed to get at least 25 raiders to 80 and then cleared all of the current expansion raid content less than three days after the launch. Fortunately for them, the next three content patches are each expected to contain new, more difficult raids.

Activision's Noah Heller sat down with Gamasutra to discuss the refinements made in Call of Duty: World at War to keep the popular FPS franchise moving forward. He points to cosmetic things, like realistic burning and the ability to set just about everything in the environment on fire, as well as bigger gameplay improvements, such as making the AI more difficult to beat without having it "cheat." "... the main thing we tried to do is honestly make the placement just more brutal. You've always got an advantage on the enemy; you've been through the level before, you know where they're going to be, but in Veteran mode you're going to find that they're not going to cheat. You're really going to have to be going for headshots using the most effective weaponry. You're going to have to use that bolt-action rifle and aim for the head if you want to take an enemy out at a distance. It's a different sort of gameplay. We heard those concerns and we tried to address them."

p1234 writes with this excerpt from the Max Planck Institute for Astrophysics: "Simulations by the Virgo team show how the Milky Way's halo grew through a series of violent collisions and mergers from millions of much smaller clumps that emerged from the Big Bang. ... If Fermi does detect the predicted emission from the Milky Way's smooth inner halo, then it may, if we are lucky, also see gamma-rays from small (and otherwise invisible) clumps of dark matter which happen to lie particularly close to the Sun. ... The largest simulation took 3.5 million processor hours to complete. Volker Springel was responsible for shepherding the calculation through the machine and said: 'At times I thought it would never finish.' Max Planck Director, Professor Simon White, remarked that 'These calculations finally allow us to see what the dark matter distribution should look like near the Sun where we might stand a chance of detecting it.'" We discussed a related simulation a few months ago.

MaxwellEdison writes "Researchers, oddly enough from the National Autonomous University of Mexico, have found a way to make diamond films using tequila. They were originally testing methods of creating the films with organic solutions like acetone when it was noticed the ideal ratios of water and ethanol turned out to be about 80 proof, or 40% alcohol. '"To dissipate any doubts, one morning on the way to the lab I bought a pocket-size bottle of cheap white tequila and we did some tests," Apátiga said. "We were in doubt over whether the great amount of chemicals present in tequila, other than water and ethanol, would contaminate or obstruct the process, it turned out to be not so. The results were amazing, same as with the ethanol and water compound, we obtained almost spherical shaped diamonds of nanometric size. There is no doubt; tequila has the exact proportion of carbon, hydrogen and oxygen atoms necessary to form diamonds."'"

rugatero writes "The BBC reports that, as of last Saturday, Microsoft is no longer issuing licenses for the 18-year-old Windows 3.x. Many here may well be surprised to learn that anyone still has use for the antiquated software, but it seems to have found a home in a number of embedded systems — including cash registers and the in-flight entertainment systems on some long-haul passenger jets (Virgin and Qantas are cited). Considering Linux's credentials as an embedded OS, this news could very well indicate the possibility of more migrations in the pipeline."

the4thdimension writes "CNN is running a story this morning that explains new research showing a correlation between video games and aggression in children. The study monitored groups of US and Japanese children, asking them to rate their violent behavior over a period of several months while they played video games in their free time. The study concludes that it has 'pretty good evidence' that there is a link between video games and childhood aggression." Stories like this make me want to smash things.

Death Metal sends in a Scientific American article reporting that 2,000 of 6,000 amphibian species are endangered worldwide. A combination of environmental assaults, including global warming, seems to be responsible. "... national parks and other areas protected from pollution and development are providing no refuge. The frogs and salamanders of Yellowstone National Park have been declining since the 1980s, according to a Stanford University study, as global warming dries out seasonal ponds, leaving dried salamander corpses in their wake. Since the 1970s, nearly 75 percent of the frogs and other amphibians of La Selva Biological Station in Braulio Carrillo National Park in the Caribbean lowlands of Costa Rica have died, perhaps due to global warming. But the really bad news is that amphibians may be just the first sign of other species in trouble. Biologists at the University of California, San Diego, have shown that amphibians are the first to respond to environmental changes, thanks to their sensitivity to both air and water. What goes for amphibians may soon be true of other classes of animal, including mammals."

An anonymous reader writes "The French Senate has approved a three strikes law for Internet users who download copyrighted entertainment media without paying for it. If, after two warnings, a person continues to download pirated music and movies, the internet service providers would cut off access for a year. Quoting: 'The legislation passed with a massive cross-party majority of 297 votes to 15. Only a handful of conservatives, centrists and socialists voted against, while the Communists abstained. In passing the bill, the senators rejected an amendment proposed by senator Bruno Retailleau of the right-wing MPF party replacing internet cut-off with a fine. ... The bill sets up a tussle between France and Brussels. In September, the European Parliament approved by a large majority an amendment outlawing internet cut-off." We discussed the introduction of this legislation several months ago.

daria42 writes "The leaders of three of Australia's largest internet service providers — Telstra Media's Justin Milne, iiNet's Michael Malone and Internode's Simon Hackett — have, in video interviews with ZDNet.com.au over the past few months, detailed technical, legal and ethical reasons why ISP-level filtering won't work. Critics of the policy also say that users will have no way to know what's being filtered."

xp65 writes with the just-announced success of Elon Musk's SpaceX's long efforts to reach orbit with a privately-developed launching craft: "T+0:08:21 Falcon 1 reached orbital velocity, 5200 m/s Nominal Second stage cut off (SECO) — Falcon 1 has made history as the first privately developed liquid fueled launch vehicle to achieve earth orbit!" dbullard adds "This was a completely new vehicle — it's not using any previously developed hardware. All developed from scratch. No government supplied hardware, Russian engines, or old ICBM motors. My hat's off to the employees of Space X — all 550 of them. (Note — no 'cast of thousands,' just 550). They've got video of the entire launch."
