Royal College of Art's Innovation Design Engineering course in collaboration with Tufts University silk lab. Not as good as it sounds as it does not fully mimic the photosynthesis equation (spare C, H atoms)

Interesting stuff and I guess it does not need to fully mimic photosynthesis in the end. As long as oxygen can be produced from CO2 and water that would be great enough. Though the carbon has to be deposited somewhere (in some form) and I wonder how one could extract this efficiently. Maybe it can even serve some purpose (as the sugars are doing for the plant)
Scientists have developed a material so dark that you can't see it... - 7 views

A British company has produced a "strange, alien" material so black that it absorbs all but 0.035 per cent of visual light, setting a new world record. To stare at the "super black" coating made of carbon nanotubes - each 10,000 times thinner than a human hair - is an odd experience.

Finally! Nowadays blacks were always too bright for my taste...

"No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it." I will keep waiting for my darkness-emitting diodes...
The Worlds Smallest Thermometer - 0 views

By attaching a diamond crystal to an AFM tip, researcher at New York City University managed to measure the heat flows at atomic levels in resistors. The method works due to a vacancy in the carbon lattice, two spots are empty of which one is filled with a nitrogen atom. The energy state of the vacancy is temperature dependent and can actually be read out spectroscopically.
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."

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.
