Submission + - Self-sustaining solar reactor creates clean hydrogen (geek.com)

An anonymous reader writes: A mechanical engineer working out of the University of Delaware has come up with a way to produce hydrogen without any undesirable emissions such as carbon dioxide.

The solar reactor is capable of using sunlight to increase the heat inside its cylindrical structure above 3,000 degrees Fahrenheit. Zinc oxide powder is then gravity fed through 15 hoppers into the ceramic interior where it converts to a zinc vapor. At that point the vapor is reacted with water separately, which in turn produces hydrogen. If the prototype gets through 6 weeks of testing at the Swiss Federal Institute of Technology located in Zurich, we could see it scaled up to industrial size, producing emission-free hydrogen.

Submission + - Want to See the Last Moment of a Stars Life? (scienceworldreport.com)

An anonymous reader writes: Researchers using NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured infrared images of the last exhalations of a dying sun-like star.

The object observed by SOFIA, planetary nebula Minkowski 2-9, or M2-9 for short, is seen in this three-color composite image. The SOFIA observations were made at the mid-infrared wavelengths of 20, 24, and 37 microns. The 37-micron wavelength band detects the strongest emissions from the nebula and is impossible to observe from ground-based telescopes.

The school checked, found the claims to be baseless and simply a fit of pique by the children in question. Did the school have the right to force the children to log into their Facebook accounts on school property to see the messages? Debatable, but again, the teacher in this case has done nothing wrong. So saying that "everyone failed" and lumping the teacher in is wrong-headed ridiculousness.

Wait, how did the teacher fail in this case? The students clearly failed because at age 12 and 13 you should know enough to not tell lies about people just because you're angry.

School district may have failed by actioning on a Facebook post not made on their computers. That's up for debate, but it is perhaps understandable that they acted to both protect the teacher and their reputations and send a message to other students that this level of name calling is not acceptable.

Parents definitely failed in not monitoring their children or teaching them appropriate impulse control. If you're going to turn control over your children to a school, then you can't act shocked when the school disciplines your child. It's great that some of the parents are considering getting lawyers and giving their children a chance to experience how the legal system works, but perhaps had the parents shown this level of interest in their children to begin with, it wouldn't have happened.

But the teacher here was just doing his job teaching students. Call a teacher stupid? Well, I suppose, although even that shows a distressing lack of respect for an authority figure who, by all accounts, hasn't done anything to warrant it. Call them a rapist, a pedophile and accuse them of mental illness? All of those are career enders for teachers (again, generally because of parents who are only involved in their children's lives when they smell a payday with a lawsuit) and, unless the student has a legitimate accusation, should require consequence.

So I see student fail, school fail and parent fail, but how the hell did the teacher fail? The teacher was maliciously and slanderously attacked for doing his job. Seriously, we've gotta stop treating teachers as second class citizens. Just lumping everyone into the blame game to seem fair or even handed is bad critical thinking and neither fair nor even handed.

4chan Declares War On Snow 201

With all the recent hacktivism in the news, Anonymous has decided to take on a new and powerful enemy: snow. On Sunday the group announced that it will "do everything in its power to shut snow down by attacking the Weather Channel and North Face websites, boycotting outerwear, and voting for the sun as Time’s 2010 Person Of The Year." I'm sure there are a lot of people in Minneapolis right now that would wish them luck.

As a sign, Earth will take two perfectly good prom dresses and rip them apart only to reassemble them in a Frankenstein's Monster creation resembling a cross between a potato sack and a straightjacket for Rainbow Bright. Then, after prom, Earth will bang Andrew McCarthy and this will somehow force Jon Cryer to star in a sitcom with the Sheen that didn't marry Paula Abdul. Yeah. That'll show 'em.

Woman Trademarks Name and Threatens Sites Using It 273

An anonymous reader writes "Be careful mentioning Dr. Ann De Wees Allen. She's made it clear that she's trademarked her name and using it is 'illegal... without prior written permission.' She even lists out the names of offenders and shows you the cease-and-desist letter she sends them. And, especially don't copy any of the text on her website, because she's using a bit of javascript that will warn you 'Copyright Protect!' if you right click on a link."

Comment So when are the other evaluations being published? (Score 1) 629

More than any other job, teaching depends on a multitude of parties "doing the right thing" in order to be successful. Teachers are definitely one of those, but the best teacher in the world can't overcome parents who aren't involved with their children, a home environment and surroundings that don't value education, children themselves who may have been taught that teachers are "bad" and the public education system is "bad" so they want none of it and school administrations which are more interested in CYA than supporting their teachers. One, maybe two, of these can break down or be sub-par and a child still might get an education. But in many systems, you've got massive cascading breakdowns in all of them. Trying to then point out the faults in just one of them is then little more than blame shifting and finger pointing. Further, because of their intertwined nature, how can you fix one of them without fixing all of them? Any improvement in one area will slowly be ground down by the interference coming from the others. Are there bad teachers? You bet there are. Maybe more than anyone would like to admit because having the desire to work with kids and education doesn't mean having the ability to navigate the current learning environment. But unless this evaluation takes into account the whole picture (kids, parents, administration, teachers and environment), it's just another bandwagon "Let's blame teachers!" torches-and-pitchforks battlecry. Even worse, its just bad journalism. It also means the teachers who the evaluation call "good" are about to get all sorts of hell unleashed on them as parents read these things and then fight, sometimes quite viciously, to have Little Billy put into the top teacher's classroom or, upon seeing Little Sally is in a "bad" teacher's classroom, well, what's the point?

Sony May Charge For PlayStation Network 212

In an interview with IGN, Sony's VP of marketing, Peter Dille, responded to a question about the PlayStation Network by saying that the company is considering charging for the service. He said, "It's been our philosophy not to charge for it from launch up until now, but Kaz recently went on the record as saying that's something we're looking at. I can confirm that as well. That's something that we're actively thinking about. What's the best way to approach that if we were to do that? You know, no announcements at this point in time, but it's something we're thinking about." This follows news of a customer survey from last month that listed possibilities for subscription-based PSN features.

Future Ubisoft Games To Require Constant Internet Access 497

Following up on our discussion yesterday of annoying game distribution platforms, Ubisoft has announced the details of their Online Services Platform, which they will use to distribute and administer future PC game releases. The platform will require internet access in order to play installed games, saved games will be stored remotely, and the game you're playing will even pause and try to reconnect if your connection is lost during play. Quoting Rock, Paper, Shotgun: "This seems like such a bizarre, bewildering backward step. Of course we haven't experienced it yet, but based on Ubi’s own description of the system so many concerns arise. Yes, certainly, most people have the internet all the time on their PCs. But not all people. So already a percentage of the audience is lost. Then comes those who own gaming laptops, who now will not be able to play games on trains, buses, in the park, or anywhere they may not be able to find a WiFi connection (something that’s rarely free in the UK, of course – fancy paying the £10/hour in the airport to play your Ubisoft game?). Then there's the day your internet is down, and the engineers can’t come out to fix it until tomorrow. No game for you. Or any of the dozens of other situations when the internet is not available to a player. But further, there are people who do not wish to let a publisher know their private gaming habits. People who do not wish to report in to a company they’ve no affiliation with, nor accountability to, whenever they play a game they’ve legally bought. People who don’t want their save data stored remotely. This new system renders all customers beholden to Ubisoft in perpetuity whenever they buy their games."
