Thin Water Acts Like a Solid 138

Roland Piquepaille writes "What happens when you compress water in a nano-sized space? According to Georgia Tech physicists, water starts to behave like a solid. "The confined water film behaves like a solid in the vertical direction by forming layers parallel to the confining surface, while maintaining it's liquidity in the horizontal direction where it can flow out," said one of the researchers. "Water is a wonderful lubricant, but it flows too easily for many applications. At the one nanometer scale, water is a viscous fluid and could be a much better lubricant," added another one."

Submission + - Canada to Ban Incandescent Bulbs by 2012

Radon360 writes: Canada will ban the sale of inefficient incandescent light bulbs by 2012 as part of a plan to cut down on emissions of greenhouse gases. Canada is the second country in the world to announce such a ban. Australia said in February it would get rid of all incandescent bulbs by 2009. The ban will not apply to uses where incandescent bulbs are still the only practical alternative.

Submission + - How to legally determine an anonymous coward's ID

CPE1704TKS writes: My girlfriend is running into a weird situation. Someone is posing as her and sending her friends on her friendster account messages asking for their IM account names. Some of them have been duped and have even engaged in conversation with this person. What can I do (legally) to determine this person's true identity.

I was able to determine this person's IP address by putting trackers on specific web pages and sent those pages to them to look at. I even set up a fake AIM account and chatted with this person, pretending to be someone who thought she was my gf.

Now what?

I have the person's IP address, and I know the city that they live in, based on it. Is there any way I can narrow down who they are? If people post grey-area or not-so-legal tactics, as a law-abiding citizen, I would never do such a heinous thing, but it would be educational to know what tricks and tips there are out there to figure out who this person is.

Encouraging Students to Drop Mathematics 618

Coryoth writes "The BBC is reporting that students in the UK are being encouraged to drop math at the senior levels. It seems that schools are seeking to boost their standing on league tables by encouraging students not to take 'hard' subjects like mathematics, in favor of easier subjects in which they are assured good grades. The result is Universities being forced to provide remedial math classes for science students who haven't done math for two years. The BBC provides a comparison between Chinese and UK university entrance tests — a comparison that makes the UK look woefully behind."

Submission + - Student arrested for quoting Columbine Killers

HoodCrowd writes: "Yuri Wainwright, 25, of Purvis, Mississippi was arrested last week for allegedly posting threatening messages on his MySpace Web page. He quoted the Columbine killers and posted other bulletins that the University of Southern Mississippi police force deemed dangerous. Those quotes can be found here. There is also an opinion piece from the enlightened student editor here. Has the good ole USA gone to the wimps? Is what he posted really worth holding him in prison for $1,000,000 bond. I am surly going to jail for the things I have posted on Slashdot."

Submission + - Auto fuel from Plants and Sun, no excess CO2

Lightness writes: As reported on PhysOrg, scientists have demonstrated that a hybrid system of hydrogen and carbon can produce a sufficient amount of liquid hydrocarbon fuels to power the entire U.S. transportation sector. Using biomass to produce the carbon, and solar energy to produce hydrogen, the process requires only a fraction of the land area needed by other proposed methods.

Needs are the usual, better solar efficiency and cheaper gassification. Can we hope for government subsidies to help this along?

Submission + - Who Resurrected the Electric Car?

mattnyc99 writes: A century after the original "electric vehicle," a decade after the Prius and a year after the Tesla, the big car companies have apparently woken up to the plug-in car revolution: The start-up battery makers are working around the clock, and Detroit bigwigs say they can make hybrid electric vehicles a reality within three years, according to a new report in Popular Mechanics. But PopMech's re-publishing of an old essay by the late, great David Halberstam—about the liberating powers of technology over time (particularly the automobile)—has to get you thinking, "When did we ever stop wanting innovative cars that save money, power and our world?"
