    http://www.nature.com/news/2010/101022/full/news.2010.558.html hmm should be the ACT in Nature, no? ;)

    Yeeesss :) So the "non-commercial" rockets do not emit soot? And how many "non-commercial" launches per year are there in comparison to the commercial ones? Finally commercial space-flight seems more realisable than ever, and "non-commercial" guys will do everything to prevent situation in which they have to compete on an open market... Coming years should be very interesting...

  • A computer simulation shows the transition from "fermionic" to "liquid" light.
  • The possibility of sending this type of "self-focused" light pulse long distances could be important for remote sensing applications, such as LIDAR, which uses laser light the way radar uses radio waves.

    what the heck is this?? sounds really strange but highly interesting to me ....

    can we use this for energy transmission?

    read it now more carefully and the answer is probably no ...

    yes, the internet is going crazy over this one :) (http://cumbriansky.wordpress.com/2010/11/30/nasas-astrobiology-press-conference/) This is the most likely scenario I've seen so far for what will be announced tomorrow: http://skymania.com/wp/2010/11/alien-life-form-is-here-on-earth.html/ "...discovery of microbes in a deadly poisonous lake that get their energy from arsenic. Experts say this shows they had a completely different origin to any other creature known on our planet. It means that life began not just once but at least twice on Earth."
  • Joris _ on 02 Dec 10
     
    well, we've all seen the movie Evolution (http://www.imdb.com/title/tt0251075/) ;p ... this is exactly this scenario indeed.
  • Ma Ru on 02 Dec 10
     
    yaaawnnn... Let's wait until they actually announce it.
  • nikolas smyrlakis on 02 Dec 10
     
    http://astrobiology.nasa.gov/ for the moment is down. My bet, the microbe they found notified its cousins and they are currently invading the US
  • Luís F. Simões on 02 Dec 10
     
    you can still see the rest of it here: http://www.nasa.gov/multimedia/nasatv/index.html a good link with a summary and discussion on the announcement is here: http://www.guardian.co.uk/science/2010/dec/02/nasa-life-form-bacteria-arsenic

    Perhaps they measured the "cold fusion" of Berlusconi with his girls. But that's not that cold, as it seems...
  • santecarloni on 25 Jan 11
     
    ...that is definitely HOT... ...on the other hand I don't think it would be fusion since it does not seems to produce any bound state... double mystery :)

    Wellwellwell! I don't know how I have to complain, since I could not yet read the full article, but I'm sure I will :-).
  • Luzi Bergamin on 02 Feb 11
     
    It's funny to see how people get more and more humble in the desperate attempt to save their stupid ideas... At the beginning was the brave and bold aim to cloak something in free space (in a sphere or a cylinder). This requires inhomogeneous, anisotropic, magnetic materials; hopeless!! So one reduces to one polarization, now we have inhomogenous, anisotropic materials; still hopeless! At this point one downgraded the pretension: instead of cloaking in free space, we make a "carpet cloak" and hide an object behind an invisible dent in a mirror. But if that shall be continuous, we still need inhomogeneity and this is very hard. So now instead of a dent we take a cone and then it is claimed to work ... for ONE polarization. But of course the cloak can't work at all incident angles... irony of fate: everything is now made from birefringent media, the antithesis of what the metamaterials dogma was at the beginning!
  • jmlloren on 04 Feb 11
     
    Hi Luzi, can you please send me the paper. We are writing a project based on sulfates and carbonates, and all this BS sounds great for the introduction (The authors used Calcite as birefringent material)
