might look a bit scary ...

Taking images through opaque, light-scattering layers is a vital capability and essential diagnostic tool in many applications. The research group of Prof. Mosk of U. Twente have started doing experiments shooting optical lasers into opaque materials in 2007, and for surprise of everyone, it turn out the light intensity after the opaque material in their experiments was orders of magnitude bigger than expected. Following these results they succeeded in taking non-invasive sharp pictures of objects hidden behind a screen of opaqueness, the so referred Super Vision in this Nature overview article.

very nice!!!

Mining the moon - now we know that the Moon's poles hold millions of tonnes of water ice, firms in the US as well as the Indian and Chinese space agencies are planning to mine this resource and sell it to space missions as fuel.

Several new components for biological circuits have been developed by researchers. These components are key building blocks for constructing precisely functioning and programmable bio-computers. "The ability to combine biological components at will in a modular, plug-and-play fashion means that we now approach the stage when the concept of programming as we know it from software engineering can be applied to biological computers.

Scientific proof, shotgun on the red couch!

this really only works if you can fall asleep instantly. If it takes you at least 10mins to sleep the whole procedure fails miserably.

An unusual signal picked up by a European space observatory could be the first direct detection of dark matter particles, astronomers say. The findings are tentative and could take several years to check, but if confirmed they would represent a dramatic advance in scientists' understanding of the universe.

Looks like crowdsourcing for astronomy stuff is already being done.

Researchers have proposed a new "acoustic topological insulator" that could help alleviate sound scattering problems by transmitting sound in certain directions without any backscattering.

If I understood correctly the triangular structure would channel the incident sound wave to a unique direction between two options, according to the rotation direction of the cylinders included in its mesh. So, one (possibly two) directions left to detect the hypothetical submarines? Very interesting though, I hope no oceanographers take measurements simultaneously to the signals as climate models will get even more wrong...!

So basically we can photograph light now. Not just detect photons but photograph LIGHT WAVES. Really clever setup BTW.

Apparently it's time for retirement of the Le Grand K, if all goes well until the middle of next year...

"One method (...) involves counting the atoms in two silicon-28 spheres that each weigh the same as the reference kilogram." Sounds like a lengthy task, but someone must keep those physics PhD students busy, I guess...

You've heard of the catastrophic effects of radiation on environments, animals and humans. A seemingly silent and invisible destroyer, radiation can make whole cities inhabitable for hundreds of years. But have you ever wondered what radiation actually looks like? There may be one image that jumps to mind. We saw the same detector setup in the room opposite to ours during the Open Day! Using uranium is just cooler. :)

AI week on BBC - interesting opportunity to get a glimpse into how the field is viewed by laymen...

Berkeley Lab researchers are using M. thermoacetica to perform photosynthesis - despite being non-photosynthetic - and also to synthesize semiconductor nanoparticles in a hybrid artificial photosynthesis system for converting sunlight into valuable chemical products.

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.

Engineer Roger Shawyer's controversial EM Drive thruster jets back into relevancy this week, as a team of researchers at NASA's Eagleworks Laboratories recently completed yet another round of testing on the seemingly impossible tech.

I like this just because it will end up on Thijs' desk :D

Interesting that the new comes in... Yahoo Finance :). Another more complete article http://nextbigfuture.com/2015/11/nasa-eagleworks-has-tested-upgraded.html

This paper introduces a novel deflection approach based on nuclear explosions: the nuclear cycler. The idea is to combine the effectiveness of nuclear explosions with the controllability and redundancy offered by slow push methods within an incremental deflection strategy. The paper will present an extended model for single nuclear stand-off explosions in the proximity of elongated ellipsoidal asteroids, and a family of natural formation orbits that allows the spacecraft to deploy multiple bombs while being shielded by the asteroid during the detonation.

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

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.
