Super-Earths Discovered Orbiting Nearby, Sun-Like Star 242

likuidkewl writes "Two super-earths, 5 and 7.5 times the size of our home, were found to be orbiting 61 Virginis a mere 28 light years away. 'These detections indicate that low-mass planets are quite common around nearby stars. The discovery of potentially habitable nearby worlds may be just a few years away,' said Steven Vogt, a professor of astronomy and astrophysics at UCSC. Among hundreds of our nearest stellar neighbors, 61 Vir stands out as being the most nearly similar to the Sun in terms of age, mass, and other essential properties."

Big Dipper "Star" Actually a Sextuplet System 88

Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

Comment Re:It's NOT time 'travel' they're suggesting (Score 1) 194

Yes thank you for pointing this out. I read something similar at a science-y blog the other day. Basically it comes about from assuming a particular form of a complex action as opposed to the standard real one. http://blogs.discovermagazine.com/cosmicvariance/2009/10/14/spooky-signals-from-the-future-telling-us-to-cancel-the-lhc Basically there is a good more or less layperson explanation about it. All this hub-bub about time travel is exaggeration.

Comment Not so fast (Score 1) 691

So after doing some digging it turns out that even the authors of the papers admit it is a somewhat shaky proposal. Basically they assumed that something called the action, a quantity in physics usually taken to be real, maybe had an imaginary part and then played around with it a bit and assumed it would have a strong effect on a scalar field (such as the Higgs). They found the imaginary part of the action had a strong dampening effect on actions even if they were minima (which are the usual ones we work with). Basically from what I have read/gathered this imaginary part appears in the form of non-local effects in space-time by forcing a consideration upon an entire trajectory through time not just what is local. So basically it would imply the universe as a whole could be on a trajectory where the Higgs just couldn't be created due to the dampening effects of the imaginary part of the action. No backwards propagating signals or anything...just the way the universe is. Of course the whole thing is pretty shaky (invoking at least two 'tooth faries') but it is fun nonetheless.

Submission + - U.S. students behind in math, science (cnn.com)

tukang writes: American children aren't necessarily getting smarter or dumber, but that might not be good enough to compete globally, according to numbers cited Tuesday by Secretary of Education Arne Duncan. He noted a special analysis put out last week by the National Center for Education Statistics that compares 15-year-old U.S. students with students from other countries in the Organization for Economic Development. It found the U.S. students placed below average in math and science. In math, U.S. high schoolers were in the bottom quarter of the countries that participated, trailing countries including Finland, China and Estonia. According to the report, the U.S. math scores were not measurably different in 2006 from the previous scores in 2003. But while other countries have improved, the United States has remained stagnant.

Submission + - FCC declares Net Neutrality will be enforced

Unequivocal writes: "FCC's Chairman Genachowski told Congress today that the "Federal Communications Commission plans to keep the Internet free of increased user fees based on heavy Web traffic and slow downloads. Julius Genachowski, the FCC chairman, told The Hill that his agency will support "net neutrality" and go after anyone who violates its tenets. "One thing I would say so that there is no confusion out there is that this FCC will support net neutrality and will enforce any violation of net neutrality principles," Genachowski said when asked what he could do in his position to keep the Internet fair, free and open to all Americans. The statement by Genachowski comes as the commission remains locked in litigation with Comcast. The cable provider is appealing a court decision by challenging the FCC's authority to penalize the company for limiting Web traffic to its consumers."

It looks like the good guys win, unless the appeals court rules against the FCC.."

Submission + - Piratebay prosecution supporter copyright scandal

An anonymous reader writes: I just read about the trouble Piratebay Prosecution lawyer Monique Wadsted has been having:
http://torrentfreak.com/pirate-bay-prosecution-hires-hypocrite-pirate-author-for-pr-090223/

I say, sue her senseless!

No, seriously. This is a big story. Here we have someone Big Content roll on to support their claim, and that person turns out to be a self-confessed habitual downloader. Ask Big Content why a such a confession does not warrant a court case. Everyone is equal to the law. They are going after individual users in several countries.

Indeed, Ms Carina Rydberg is in serious trouble:
1. she possesses IP material and she has made illegal copies with the intent to distribute this material. Furthermore, this is in her professional capacity, as an author. Which means she breaks IP laws for commercial purposes.
2. Her comment "If someone [...] chose to download the book I wrote in 1989 I would have no objection to that" further burdens the case against her. For any such download to happen, the book will have to be uploaded first. Arguably Ms Rydberg is soliciting someone else to break the IP laws here.
3. Upon being discovered as an habitual downloader, Ms Rydberg tried to destroy evidence. This arguably adds malicious intent on her part to the case! In short Ms Rydberg has broken nearly every paragraph in today's IP laws, inlcuding the far serious "for commercial gain" and "malicious intent" issues. Big Content has a perfect case for sueing the pants off her, and demanding $ tens of thousands in damages from her.

Sad that, as a DVD of "The day of the locust" can be picked up for as little as 9.99 in my local Kruidvat ;-).

Comment Re:Mercury (Score 2) 1056

You make it sound like they put pure mercury into them. Ethylmercury does not bioaccumulate like the more dangerous methylmercury which is NOT in vaccines. Even upon removing it there was no real change in autism rates. The last statement though is a current area of research--there may very well be some environmental factor. Certainly the environment we live in today is far different than that of the past; there are whole hosts of new chemicals ingested by mothers or infants, food sources have different levels of heavy metals in them etc. That is why there is currently a large scale national study getting launched to try and figure out some of these potential environmental factors since the vaccine route was long ago dismissed.

Stone Tool 1.83M Years Old Discovered In Malaysia 200

goran72 writes with news out of Malaysia that archaeologists have announced the discovery of stone tools more than 1.8 million years old — the earliest evidence of human ancestors in South-east Asia. Researchers believe the tools were made by members of the early human ancestor species Homo erectus. The tools actually date as slightly older than the earliest H. erectus fossils, which came from Georgia and China. No bones of that antiquity have so far been found in Malaysia. "The stone hand-axes were discovered last year in the historical site of Lenggong in northern Perak state, embedded in a type of rock formed by meteorites which was sent to a Japanese lab to be dated."

Well in a sense it is already known how the Maxwell equations would transform with hypothetical monopoles (you get the divergence of B to look like the divergence of E and there is a "monopole current" term in the curl of E equation). In any region where there isn't a monopole everything would remain the same, so nothing already known changes. But for regions where we'd have these monopole like things quite a few equations where you wind up with div B would become more interesting to say the least!

32bit Win7 Vs. Vista Vs. XP 641

An anonymous reader writes "ZDNet's Adrian Kingsley-Hughes tested the latest Win7 build against XP and Vista and came to a surprising conclusion: Win7 performs better than the other 2 OSs in the vast majority of the 23 tasks tested. Even installation. 'Rather than publish a series of benchmark results for the three operating systems (something which Microsoft frowns upon for beta builds, not to mention the fact that the final numbers only really matter for the release candidate and RTM builds), I've decided to put Windows 7, Vista and XP head-to-head in a series of real-world tests...'" This review shows only a 1-2-3 ranking for each test, so there's no sense of the quantitative level of improvement.
