This is the biggest breakthrough in game AI (and one of the biggest in AI in general) since Deep Blue beat Kasparov in chess: For the first time, a human professional player was defeated in the game of Go. The approach was a combination of tree search and deep neural networks. Very proud of a former colleague on the team at Google Deepmind!

Funny enough, facebook also had a very similar paper around the same time.

seems also potentially useful for astronauts ...

For the first time, researchers have shown that they can capture CO2 from the air, and convert it directly into methanol, which can then be used as an alternative fuel, as well as for hydrogen storage, in fuel cells, or as a building block for plastic.

Solar power to suck out co2 during the day and make it fuel finally solves global warming?

Ancient Babylonian astronomers developed many important concepts that are still in use, including the division of the sky into 360 degrees. They could also predict the positions of the planets using arithmetic. Ossendrijver translated several Babylonian cuneiform tablets from 350 to 50 BCE and found that they contain a sophisticated calculation of the position of Jupiter.

I still have my doubts that this mission will ever happen as announced but this is a first step...

Good old Darwin...

curious ...

interesting move! Luxembourg - the silicon valley for space entrepreneurs in Europe ...?

Can you handle Quantum Chess...Well, can you, Hendrik?

very nice! "For a start, the wires operate well as switches that by some measures compare well to field effect transistors. For example they allow a million times more current to flow when they are on compared with off when operating at a voltage of about 1.5 V. "[A light effect transistor] can replicate the basic switching function of the modern field effect transistor with competitive (and potentially improved) characteristics," say Marmon and co. But they wires also have entirely new capabilities. The device works as an optical amplifier and can also perform basic logic operations by using two or more laser beams rather than one. That's something a single field effect transistor cannot do."

any idea how the shine the light selectively to such small surfaces?

"Illumination sources consisted of halogen light, 532.016, 441.6, and 325 nm lasers ported through a Horiba LabRAM HR800 confocal Raman system with an internal 632.8 nm laser. Due to limited probe spacing for electrical measurements, all illumination sources were focused through a 50x long working distance (LWD) objective lens (N.A. = 0.50), except 325 nm, which went through a 10x MPLAN objective lens (N.A. = 0.25)."

'Whether mysterious high-energy photon emissions from our Galaxy come from dark matter or a more mundane source might be resolved by detecting their Doppler shifts along different lines-of-sight.'

Proximity to the transmitter impacts power delivery as follows: 4W delivered to 4 devices simultaneously within 0-5 feet 2W delivered to 4 devices simultaneously within 5-10 feet 1W delivered to 4 devices simultaneously within 10-15 feet How to make a piecewise approximation of one inverse square law for commercial purposes

:-) - which also tells us that these are not measured values but estimations it seems to me ...

In the wake of the financial crisis, many started questioning different aspects of the economic formalism. Here a mathematical "dynamic" alternative to economic utility theory (which has also been the target of some famous recent attacks, see prospect theory) is developed and applied to the St. Petersburg coin tossing paradox. A good read at http://scitation.aip.org/content/aip/journal/chaos/26/2/10.1063/1.4940236

Microsoft project Natick deploys cloud servers inside a vessel under seawater. A cool story about crossing competences of different people around an innovative solution. "In my experience the trick to innovating is not coming up with something brand new, but connecting things we've never connected before, pairing different technology together."

the quote could come from ACT ...

After the Go, real-time RPG as Hendrik alluded?

interesting study showing seasonal changes to brain functions Agata, you didn't tell us about this yet :-) "the present study provides compelling evidence for previously unappreciated annual varia- tions in the cerebral activity required to sustain ongoing cognitive processes in healthy volunteers. The data further show that this annual rhythmicity is cognitive-process-specific (i.e., the phase of the rhythm changes between cognitive tasks), speaking for a complex impact of season on human brain function. Annual var- iations in cognitive brain function may contribute to explain intraindividual cognitive changes that could emerge at specific times of year."

Thank you for this interesting study. I will make a brief intro about it during our Wednesday meeting. Especially, that spring is coming...;)
