U of MI Produces Strongest Laser Ever 244

eldavojohn writes "Weighing in at a mere 20 billion trillion watts per square centimeter and containing a measly 300 terawatts of power, the University of Michigan has broken a record with a 1.3-micron speck wide laser. It's about two orders of magnitude higher than any other laser in the world and can perform for 30 femtoseconds once every ten seconds — some of the researchers speculate it is the most powerful laser in the universe. 'If you could hold a giant magnifying glass in space and focus all the sunlight shining toward Earth onto one grain of sand, that concentrated ray would approach the intensity of a new laser beam made in a University of Michigan laboratory ... To achieve this beam, the research team added another amplifier to the HERCULES laser system, which previously operated at 50 terawatts. HERCULES is a titanium-sapphire laser that takes up several rooms at U-M's Center for Ultrafast Optical Science. Light fed into it bounces like a pinball off a series of mirrors and other optical elements. It gets stretched, energized, squeezed and focused along the way.'" And ... cue the evil chortling.

Submission + - Origin of Antimatter Cloud Discovered

Active Seti writes: "Scientists have proposed a wide range of explanations for the origin of antimatter, which is exceedingly rare in the cosmos. For years, many theories centered around radioactive elements produced in supernovae. Now four years of observations from the European Space Agency's Integral satellite may have cleared up one of the most vexing mysteries in our Milky Way: the origin of a giant cloud of antimatter surrounding the galactic center. Integral found that the cloud extends farther on the western side of the galactic center than it does on the eastern side. This imbalance matches the distribution of a population of binary star systems that contain black holes or neutron stars, strongly suggesting that these binaries are churning out at least half of the antimatter, and perhaps all of it. The antimatter is probably produced in a region near the neutron stars and black holes, where powerful magnetic fields launch jets of particles that rip through space at near-light speed. "We expected something unexpected, but we did not expect this," says Gerry Skinner, co-investigator for Integral's Spectrometer which made the discovery."

Submission + - Senate Approves Immunity for Illegal Wiretapping (yahoo.com)

An anonymous reader writes: Senate just passed a bill with an overwhelming majority that will grant immunity to all the telephone companies that participated in the illegal wiretapping. Senate contends that "(Telephone) companies should be thanked, not punished, for helping defend the United States (by helping with illegal wiretapping)". From the article "The Senate bill would provide new protections of civil liberties, such as requiring tougher congressional and judicial oversight." With a congress and judiciary like this say goodbye to our liberties.

Submission + - Time Warner Cable Wins State-Wide Cable Franchise (state.oh.us) 1

An anonymous reader writes: Time Warner Cable has received the second state-wide franchise agreement, covering 260 communities, in 60 of Ohio's 88 counties, for 10 years. AT&T was the first to earn a state-wide franchise contract, after a law was passed in September that allowed operators to negotiate a single state-wide agreement. Normally operators negotiate franchise agreements at the local level.

Submission + - Should Wikipedia Allow Mathematical Proofs? (wikipedia.org) 4

Beetle B. writes: "An argument has arisen over whether Wikipedia should allow pages that provide proofs for mathematical theorems (such as this one).

On the one hand, Wikipedia is a useful source of information and people can benefit from these proofs. On the other hand, how does one choose which proofs to include and which not to? Should Wikipedia just become a textbook that teaches mathematics? Should it just state the bare results of theorems and not provide proofs (except as external links)? Or should they take an intermediate approach and formulate a criterion for which proofs to include and which to exclude?"

Submission + - Canadian DMCA protest (boingboing.net) 1

ThePurpleBuffalo writes: Cory Doctorow has announced that Jim Prentice will be in Calgary, Alberta, Canada tomorrow (Saturday, 2007-12-10) and that this might be the best chance to fight the Canadian DMCA. From the article: "If you're a Canadian and you want to talk to Industry Minister Jim Prentice about his proposal for a Canadian DMCA, a copyright law that's even worse than the ten-year-old American legislation that resulted in lawsuits against 20,000+ Americans without stopping infringement or paying artists, now's your chance!"

Submission + - New Theory Explains Periodic Mass Extinctions

i_like_spam writes: The theory that the dinosaurs were wiped out by an asteroid impact, the K-T extinction, is well known and supported by fossil and geological evidence. Asteroid impact theory does not apply to the other fluctuations in biodiversity, however, which follow an approximate 62 million-year cycle. As reported in Science news, a new theory seems to explain periodic mass extinctions. The new theory found that oscillations in the Sun relative to the plane of the Milky Way correlate with changes in biodiversity on Earth. The researchers suggest that an increase in the exposure of Earth to extragalatic cosmic rays causes mass extinctions. Here is the original paper describing the finding.

Submission + - Microsoft delays Office 2008 for Mac until mid-Jan (appleinsider.com)

i_hate_robots writes: AppleInsider is reporting that Microsoft's Macintosh Business Unit (Mac BU) said Thursday that the release of Microsoft Office 2008 for Mac has been pushed back from the second half of 2007 until mid-January. The Redmond-based firm now anticipates showing a final version of the software at the Macworld trade show and conference in January, with global availability to commence in the first quarter of 2008. "This was a business decision based on the Mac BU's commitment to deliver a high-quality product," said Mac BU General Manager Craig Eisler. "Our number one priority is to deliver quality software to our customers and partners, and in order to achieve this we are shifting availability."

Submission + - Do Not Call Registry gets wake-up call (networkworld.com) 2

coondoggie writes: "If you signed up for the federal or your state's Do Not Call Registry a few years ago, you might want to thing about refreshing it. Pennsylvanians this week got a wake up call, so to speak from the state's Attorney General Tom Corbett who kicked off a public awareness campaign designed to remind people what many have forgotten or never knew — that the 2002 law set registrations to expire after five years. That is of course unless you want to start hearing from those telemarketers as you sit down to dinner. Corbett said about 2 million people signed up in the immediate aftermath of the law taking effect and those who do not act by Sept. 15 will have their numbers dropped from the registry on Nov. 1. The Pennsylvania action is a reminder that the National Do Not Call Registry has a five year life span as well. The Federal Trade Commission is set to being a nation campaign in Spring 2008 to remind all US citizens to refresh their federal Do Not Call Registry standing. http://www.networkworld.com/community/node/18066"
