    By wearing clothes that have been dip-coated in a silver nanowire (AgNW) solution that is highly radiation-insulating, a person may stay so warm in the winter that they can greatly reduce or even eliminate their need for heating their home. With as extra bonus: Besides providing high levels of passive insulation, AgNW-coated clothing can also provide Joule heating if connected to an electricity source, such as a battery. The researchers demonstrated that as little as 0.9 V can safely raise clothing temperature to 38 °C, which is 1 °C higher than the human body temperature of 37 °C. How about that for personal comfort during the cold winter months

    These applications seem more and more promising. However I wonder about the toxicity aspects of wearing this stuff and apparently some research is starting to be developed to assess that, see http://www.particleandfibretoxicology.com/content/11/1/52 showing results of pulmonary toxicity of AgNW

    Sure looks interesting, hopefully it will gain some traction. Bonus point it uses Python heavily :) First versions are coming out in Sept/Oct, according to their roadmap, we could start playing with it as soon as it gets out.

  • De Vine and colleagues therefore designed a laboratory scale version of LISA and showed they were able to suppress two potentially damaging noise sources: phase fluctuations in the clocks that synchronize the measurements and frequency fluctuations in the lasers.

    To Coordinating Lead Authors, Lead Authors, and Review Editors for the Fifth Assessment Report (AR5) "I would also like to emphasize that enhanced media interest in the work of the IPCC would probably subject you to queries about your work and the IPCC. My sincere advice would be that you keep a distance from the media and should any questions be asked about the Working Group with which you are associated, please direct such media questions to the Co-chairs of your Working Group and for any questions regarding the IPCC to the secretariat of the IPCC." and an amusing related memo on how to deal with reporters if you can't avoid them. I particularly enjoyed the list of words that mean one thing to scientists and something else to other people. https://docs.google.com/fileview?id=0B88iFXWgVKt-NDc2N2FiM2QtYzQzYS00MWMxLWE4MGEtZjUwZDlmNzc3MTcz&hl=en

    quite weird this note of IPCC... I feel more like people have to be educated...
  • Nicholas Lan on 21 Jul 10
     
    i agree. however, (and perhaps it would have been useful to post my source which didn't seem so interesting at the time) the contents of this particular memo seems to have been interpreted as a more or less direct consequence of "ClimateGate" rather than standard practice. http://freakonomics.blogs.nytimes.com/2010/07/14/what-we-talk-about-when-we-talk-about-climate-change/ On the other hand, I'd suggest that talking to the press is not necessarily a great way of educating the public, there being some truth i think to the contents of the memo.
  • LeopoldS on 21 Jul 10
     
    don't know why this seems weired or shocking - looks like some good practice advice to me
  • pacome delva on 21 Jul 10
     
    well compare to ESA it's sure it doesn't seem weird. Imagine one second a journal article about climate change: "We contacted Dr. X of the IPCC, who refused to answer to our questions..."
  • LeopoldS on 22 Jul 10
     
    this is not what the memo recommends ... it just says speak only about what you can confidently speak about and refer to others for other questions ...

LeopoldS liked it
  • Researchers are reporting that they've made batteries and other energy-storage devices by printing layers of carbon nanotube–based ink atop standard photocopy paper. The result is a highly conductive sheet that can carry a charge and be easily incorporated into a flexible battery. Because of paper's low cost, that could help lower the price of batteries used in electric vehicles, wind farms, and other renewable sources.

shared by pacome delva on 16 Mar 10 - Cached
  • Researchers in the US and Korea have discovered that igniting a carbon nanotube, coated in chemically flammable material, can trigger a high-speed wave to race along the tube at 10,000× the speed of the spreading chemical reaction. The new phenomenon, dubbed a "thermopower wave", could lead to a new way of generating electricity and may enable micro power sources to drive nanoscale devices.

    indeed ... you are right .... interesting project btw - they started in 1999, were in 2005 the first NASA project on Sourceforge and won several awards .... then this entry why they did not participate last year: "05/01/09: Skipping this years Google Summer-of-Code - many of you have asked why we are not participating in this years Summer of Code. The answer is that both John and Peter were too busy with other assignments to set this up in time. We will be back in 2010. At least we were able to compensate with a limited number of NASA internships to continue some of last years projects." .... but I could not find them in this years selected list - any clue?

    but in any case, according to the apple guru, Java is a dying technology, so their project might as well ...

    They participate under the name "The Java Pathfinder Team" (http://babelfish.arc.nasa.gov/trac/jpf/wiki/events/soc2010). It is actually a very useful project for both education and industry (Airbus created a consortium on model checking soft, and there is a lot of research on it) As far as I know, TAS had some plans of using Java onboard spacecrafts, 2 years ago. Not sure the industry is really sensible about Jobs' opinions ;) particularly if there is no better alternative!

    I've just read a blog entry about this on New Scientist, and while the entry itself is not interesting, I learned from it where the UKSA and ESA's UK establishment are going to be based. Answer: it's even more in the middle of nowhere than Plymouth! BTW does anyone (Leo?) know what is the basis on which new ESA establishments locations are chosen (if this info is classified, you can send it on priv ;) [Edit] Esa has released a news item about it... Whatever one can say about the British Space Agency, they certainly have a fantastic logo!

    wtf is this! As I read this morning in the newspaper (not even a scientific one), 1 TeV is the kinetic energy of a flying mosquito... so be careful ! It seems they already sloved every thing on this website: "At the Institute for Space Quantum Physics ISQP, it was already proved in 1991-1992 that dark matter is in magnetic fields as magnetic space quantum flux." This website is the biggest source of crackpots i have seen in a long time...! (http://www.supernovae-energy.com/)

    Unfortunately, most information I have about the guy (Hans Lehner, a Swiss) is in German, his official homepage is http://www.rqm.ch/ According to EsoWatch he is the Swiss analogue to Dr. Mills and his Blacklight power. Lehner apparently founded a company, which should have produced a "Raum-Quanten-Motor" that -- of course -- produces energy out of nothing. The theory is based on spookey forces mediated by Lehneronen. 11 Million Swiss Franks (about 8 Million Euro) were lost when the company bankrupt. And the guy is selling new stocks on his homepage again... Lehner calls another crackpot named Oliver Crane Zweistein (from Einstein being "Onestone") and himself "Dreistein". Now he is looking for Mister or Misses Vierstein. Perhaps you should apply, good luck!!

    "The first thing everyone did after seeing the energy graph on the family PC was to turn off the lights". Kind-of we are becoming slaves of the technology. Do we really need a sensor to tell us to turn-off the light when we are leaving the room!?
