Comment Re:The advantages aren't clear (Score 1) 195

These are lithium cells fabricated in a fancy way. This sort of nanoscale construction of the electrode materials affords massive surface area so you get advantages like improved capacity, power, lifetime, etc.

As with all lithium cells these are suited to applications which benefit from high energy density and low power, i.e. laptops, mobile phones etc.

'Mega-efficient' is probably a bit misleading, don't get carried away thinking all of a sudden there's a new portable energy source with the potential to replace all existing batteries!

Submission + - Brian May Successfully Defends Thesis->

DynaSoar writes: "Brian May http://en.wikipedia.org/wiki/Brian_May, lead guitarist for Queen http://en.wikipedia.org/wiki/Queen_(band) has successfully defended his astrophysics thesis at London's Imperial College http://www.msnbc.msn.com/id/20424659/. He still must resubmit his written thesis after making required corrections, but this is pro forma. He is to formally receive his doctorate in May 2008, nearly 40 years after turning from his studies to become a professional musician. The subject of his thesis, entitled "Radial Velocities in the Zodiacal Dust Cloud," is based on work he did in Tenerife in the 1960's. He has two prior scientific publications on this topic, in the Monthly Notices of the Royal Astronomical Society (166, 429 — 448 (1974)), and in Nature (240, 401 — 402 (15 December 1972))."

Submission + - UK charme offensive to extend copyright protection

benesch writes: "An ageing UK star lineup tries to charm parliament into exending copyright protection of their songs: "Sir Paul McCartney and Sir Cliff Richard are among the artists who will see the current 50-year limit on their early sound recordings expire soon. The House of Commons culture committee said people had a "moral right" to keep control of their creations while alive. The copyright term for sound recordings should be extended to at least 70 years, the committee recommended. That would allow ageing performers to continue to benefit from their early recordings throughout their lifetimes.""

Submission + - Should Copyrights Last as Long as ideas?

The_Rook writes: In an opinion piece in the New York Times, "A Great Idea Lives Forever. Shouldn't Its Copyright?" Mark Helprin, author of "Winter's Tale," equates copyrights on written works like novels, etc. with physical assets like houses, flour mills, travel agencies, and newspapers. Apparently 70 years after his death is not enough for Mr. Helprin. He wants his descendants to own the copyright on his works forever.

On the way he laments that the Constitution says copyrights are to be granted for "limited times" and is thankful that congress can and has periodically extended the length of copyrights.

Lost on Mr. Helprin is that the entire value of an idea is it's usefulness to others and that public domain enriches more than "stockholders of various businesses."

The essay is not particularly well thought out and is perhaps beneath the attention of the Slashdot community. But it needs to be refuted on the grounds that is perpetuates the fallacy that intellectual property is the same as physical property and that authors have always had right to their intellectual property (which the nasty government has seen fit to take away) rather than the real situation where intellectual property is a fiction created by the government to encourage the creation and publication of creative works.

Submission + - Limited Rights Art

qeorqe writes: An art exhibit titled "To Get to The Other Side" opened 5/11/07 at CMU's Regina Gouger Miller Gallery. One of the art pieces had an interactive computer component dealing historically with government violation of The United States Bill of Rights. The interactive component is available at limitedrights.us. Beware it uses flash.

It shows the Bill of Rights. When an era is selected some phrases become obscured. Scrolling over the Bill of Rights magnifies that portion. Clicking an obscured portion produces an explanation of the violation.

Below is an example from the Civil War era.

Article the Sixth
In all criminal prosecutions, the accused shall enjoy the right to a xxxxxx xxx xxxxxx trial, by an impartial jury of the state and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the assistance of counsel for his defense.

The x's represent "speedy and public". Clicking would reveal "1861 President Abraham Lincoln suspends Habeas Corpus and 13,000 people are held without trial."

Submission + - AACS New Media Key Block Hacked Before It's Releas

mrneutron2004 writes: It's ironic that after all of these years, licensing authorities like the AACS still don't understand the tenacity of hackers, programmers, and consumers intent on doing as they see fit with the content they pay for. A week before the official rollout of new "MKB's" designed to protect new high-definition media, Slysoft releases an update to AnyDVD-HD that can already bypass it. http://www.fastsilicon.com/latest-news/aacs-new-me dia-key-block-hacked-before-its-released.html

Submission + - ABC - takes Gravel and Paul out of running

isotope23 writes: After leaving Ron Paul out of their online poll for "who won the Republican debates"? ABC now has left both Paul and Gravel out of their list of candidates running for president in 2008 How exactly does ABC "overlook" including the two staunchly anti-war candidates (both of whom were in nationally televised debates) in their list? Does ABC stand for "Already Been Chosen" at this point? Update after pressure from Digg users, ABC has listed Paul in their poll and restarted it, however both Gravel and Paul are still not listed in the PDF.

Submission + - AMD Nearly Out Of Cash

An anonymous reader writes: Following a horrible quarter and market share losses, AMD is within two quarters of running out of cash, according to EETimes. "AMD lost approximately $883 million in free cash flow in the last quarter, worse than expected, and putting the company within two quarters of running out of cash," EETimes quotes Wall Street analyst Chris Caso as saying. It gets even worse for AMD. After losing significant market share in 2006, Intel struck back in the first quarter of 2007, gaining 4.5 percentage points in the microprocessor market. Intel now holds 80.2 percent of the global chip market. Can AMD dig itself out of a hole? Maybe, maybe not. "AMD will look to lessen the capital needs of its models by outsourcing production and partnering up, though we believe this could take much longer than investors anticipate," analyst Doug Freedman of American Technology Research told EETimes.
