Morphing Metals 121

aarondubrow writes "Imagine a metal that 'remembers' its original, cold-forged shape, and can return to that shape when exposed to heat or a magnetic pulse. Like magic out of a Harry Potter novel, such a metal could contract on command, or swing back and forth like a pendulum. Believe it or not, such metals already exist. First discovered in 1931, they belong to a class of materials called 'shape memory alloys (SMA),' whose unique atomic make-up allows them to return to their initial form, or alternate between forms through a phase change."

i totally agree with you on this, i don't think CCTV or however you want to call it will solve anything, on the contrary... it gives governments and police a very powerful tool to dominate the masses ("we have proof you know!") while at the same time it leaves "them" (authorities, cops,...) in a position where they can cover up their own actions. This reminds me of David Brin's masterpiece "Earth", in which the "right to privacy" was swapped around into a "right to knowledge". If police/politicians demand cameras on every streetcorner to monitor the people, then we as people should "arm" ourselves with cameras as well and make sure we have footage of their actions as well, so we can provide "proof against proof" if need be! it's about time we demand transparancy from our ruling elites! (and yup, that also means ending the secrecy of banks) Freedom is not free, it requires a continuous struggle against those who seek to take it from us by force or deception!

Fine-Structure Constant Maybe Not So Constant 105

Kilrah_il writes "The fine-structure constant, a coupling constant characterizing the strength of the electromagnetic interaction, has been measured lately by scientists from the University of New South Wales in Sydney, Australia and has been found to change slightly in light sent from quasars in galaxies as far back as 12 billion years ago. Although the results look promising, caution is advised: 'This would be sensational if it were real, but I'm still not completely convinced that it's not simply systematic errors' in the data, comments cosmologist Max Tegmark of MIT. Craig Hogan of the University of Chicago and the Fermi National Accelerator Laboratory in Batavia, Ill., acknowledges that 'it's a competent team and a thorough analysis.' But because the work has such profound implications for physics and requires such a high level of precision measurements, 'it needs more proof before we'll believe it.'"

i guess you don't visit /. all that much?? we had an article here about a week or two ago about this very subject... how artists are being sucked dry by the record companies, at the same time as the public is being sucked dry... capitalist companies are money-sponges mate! and no, i'm not fetching you the link, i'm a lazy b*st*rd :P

That implies 4/7ths of the planets in the galaxy are "Earth sized."

no it does not imply that, with the short time Kepler's been going now, they can only have confirmed planets in orbits very close to their star. Closer proximity to the star means stronger solar winds, to name but one of the many possible reasons why there might be a stronger tendency towards smaller planets close to the star, as opposed to further out.. (just think of the line-up of our own solar system for that if you like... other than Pluto the small ones are all in the centre, and Pluto is not really "part" of our planetary system anyway since it's on such a weird orbit all of it's own it seems it might just as well be a captured object from a different system..)

sorry but you've got your facts wrong, the ISS is a PLATFORM FOR SCIENTIFIC RESEARCH, i really fail to see how you could think that the first 10 years of Apollo-era could have spawned more science than that, since those first 10 years spawned mainly rocket-tech while today they're conducting researches in most, if not all, scientific fields up there.... (i do however agree that, generally speaking, most people are a bunch of bastards)
