Cheap materials could make grid battery storage feasible @techreview @nature - 0 views

  •  
    The new battery, which is described in the journal Nature, is based on an organic molecule-called a quinone-that's found in plants such as rhubarb and can be cheaply synthesized from crude oil.

Have We Been Interpreting Quantum Mechanics Wrong This Whole Time? - 6 views

  •  
    "The experiments involve an oil droplet that bounces along the surface of a liquid. The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet's interaction with its own ripples, which form what's known as a pilot wave, causes it to exhibit behaviors previously thought to be peculiar to elementary particles - including behaviors seen as evidence that these particles are spread through space like waves, without any specific location, until they are measured." Pilot-wave theory reresurrected. Maybe something for the next "fundamental" :P physics RF?

    And for the next 'Experimental Physics Stagiaire' position why not try to do "Unpredictable Tunneling of a Classical Wave-Particle Association" http://stilton.tnw.utwente.nl/people/eddi/Papers/PhysRevLett_TUNNEL.pdf, there are some rumors online that the results of Yves Couder Experiments can be reproduced with simple DIY vibrating tables! It is very funny to see the videos of the MIT's replication of this experiment (with lightening legends for those who are uncomfortable with the concepts involved https://www.youtube.com/watch?v=YF5iHQMjcsM)

Critique of 'Debunking the climate hiatus', by Rajaratnam, Romano, Tsiang, and Diffenba... - 8 views

  •  
    Hilarious critique to a quite important paper from Stanford trying to push the agenda of global warming .... "You might therefore be surprised that, as I will discuss below, this paper is completely wrong. Nothing in it is correct. It fails in every imaginable respect."

    why is this just put on a blog and not published properly?
  •  
    If you read the comments it's because the guy doesn't want to put in the effort. Also because I suspect the politics behind climate science favor only a particular kind of result.

    just a footnote here, that climate warming aspect is not derived by an agenda of presenting the world with evil. If one looks at big journals with high outreach, it is not uncommon to find articles promoting climate warming as something not bringing the doom that extremists are promoting with marketing strategies. Here is a recent article in Science: http://www.ncbi.nlm.nih.gov/pubmed/26612836 Science's role is to look at the phenomenon and notice what is observed. And here is one saying that the acidification of the ocean due to increase of CO2 (observed phenomenon) is not advancing destructively for coccolithophores (a key type of plankton that builds its shell out of carbonates), as we were expecting, but rather fertilises them! Good news in principle! It could be as well argued from the more sceptics with high "doubting-inertia" that 'It could be because CO2 is not rising in the first place'', but one must not forget that one can doubt the global increase in T with statistical analyses, because it is a complex variable, but at least not the CO2 increase compared to preindustrial levels. in either case : case 1: agenda for 'the world is warming' => - Put random big energy company here- sells renewable energies case 2: agenda for 'the world is fine' => - Put random big energy company here - sells oil as usual The fact that in both cases someone is going to win profits, does not correllate (still not an adequate statistical test found for it?) with the fact that the science needs to be more and more scrutinised. The blog of the Statistics Professor in Univ.Toronto looks interesting approach (I have not understood all the details) and the paper above is from JPL authors, among others.

Small, cheap gravity gadget to peer underground - BBC News - 2 views

  •  
    According to their Nature article, they can detect "a tunnel less than 1m across, buried 2m underground" just from its gravitational difference. Using a device that they predict could cost ~100 € in mass production. UK researchers have built a small device that measures tiny fluctuations in gravity, and could be used to monitor volcanoes or search for oil. Such gravimeters already exist but compared to this postage stamp-sized gadget, they are bulky and pricy.
