Bio-hacking/cyborg: implanting rare-earth magnets into your fingers to sense magnetic fields. At the same time quite awesome and quite extreme.

"By extension, GCMs are not fit for the purpose of justifying political policies to fundamentally alter world social, economic and energy systems. It is this application of climate model results that fuels the vociferousness of the debate surrounding climate models."

but you know wo these global warming policy foundation is, do you? they are the main advocacy group for climate change deniers in the UK, nothing scientific to start with; fine to post here reasonable scientific papers criticising global climate models but please not this shit

Commit Assist Tool allows predicting bugs in large code bases typically found in AAA-games.

Scientists anticipate the output would be more than twice the power used to heat the plasma, achieving the ultimate technical milestone: positive net energy from fusion.

wow, i want to do that !!! The suggestion of raising the funds on facebook is a good idea :) Look at this video, the future of banking, frightening isn't it ? http://www.youtube.com/watch?v=cqESjpfb3OE&feature=player_embedded

the first step is already not that trivial it seems to me: STEP 1: Form a bank.

depends on the country and of course the type of the bank :)

A nice programming guide explaining thoughts I often try to pass on

The fact that this article is written in two languages, one is english and the other one is russian...? I get the impression that russians are among the first to hit upon such barriers before the rest of us do, from scaling their programming to bumping upon theory of chaos etc etc Imho.

It may be feasible to use this in the Marsian atmosphere (9mbar CO2) to directly grow Carbon Nanofibres for infrastructural needs

nice!

gave it to Hanna, she is looking into it now. Manchester and Ghent University could be potential collaborators.

Prediction-based method for encouraging reinforcement learning agents to explore their environments through curiosity (reward for unfamiliar states). Learns some games without any extrinsic reward!

Fun failure case: agent gets stuck in front of TV.

Not read this article but on a related note: Curiosity and various metrics for it have been explored for some time in robotics (outside of RL) as a framework for exploring (partially) unfamiliar environments. I came across some papers on this topic applied to UAVs when prep'ing for a PhD app. This one (http://www.cim.mcgill.ca/~yogesh/publications/crv2014.pdf) comes to mind - which used a topic modelling approach.

Some people answering the question 'What's cooler than blasting space debris with lasers...?'.

If it fires in both directions, can we align it such that it deorbits two debris with one shot?

:) the idea of having this method for debris removal is actually an ACT one from Claudio Bombardelli (ACT RF in MAD https://en.wikipedia.org/wiki/Ion-beam_shepherd). This is just a technological device to implement it so that the system on board is simplified (i.e. instead of two engines, you get away with one and a weird nozzle) Marcus, you cannot align it to get rid of two debris as you need to keep the spacecraft close to the debris as this is a long duration acion. One of the two would drift away (can only follow one!)

I know you like these... [Edit] And by the way, this website contains also more practical stuff, like this

of course, "they" being Polish Wikipedia contributors who geo-tag like mad...

Have you had a look on Japan? It looks like they just geo-tagged all their train stations.

We should apply this also for space habitats

Yeah, put everything in a computer and let it think about it.

Showing why epycicles worked so well

I would troll the world and do a GR theory using epicycles :)

Genetic algorithms are a competitive alternative for training deep neural networks for reinforcement learning. For paper see: https://arxiv.org/pdf/1712.06567.pdf

Interesting pointers in this one! I would like to explore neuroevolution as well, although it seems extremely resource-demanding?

Not necessarily, I think it can be made to be much faster hybridizing it with backprop and Taylor maps. Its one ideas in the closet we still have not explored (Differential Intelligence: accelerating neuroevolution).

A quick checklist to detect what sort of papers about blockchain are bullshit.

The B report shares the same conclusions and angle ...

Two ways of measuring the universe's expansion rate yield two conflicting answers. Many point to the possibility of new physics at work, but a new analysis argues that unseen errors could be to blame. See also this work based on GAIA data that, on the other hand, reinforces the discrepancy: Milky Way Cepheid Standards for Measuring Cosmic Distances and Application to Gaia DR2: Implications for the Hubble Constant https://arxiv.org/abs/1804.10655

Norwegian scientist Kristian Morten Olesen has patented a process to mix nano-particles of clay with water and bind them to sand particles to condition desert soil - he has been working on Liquid Nanoclay (LNC) since 2005.

The news here that some patent has been filed. If it actually works the guy is an ass for wanting to patent something that is solving world hunger. If it does not, then the guy is still an ass. So the news is that this guy is an ass :)

Agreed :) But, if it does work I doubt the guy will be able to enforce the patent in most of the countries where this will be helpful.

Dataset automatically constructed from public images uploaded by users on FB/Instagram with hashtags used as labels! They refer to this as 'weakly supervised learning'. Then neural net fine-tuned for ImageNet and achieved record 85.4% accuracy.

Amazing engineering feat: 1 nm transistor. Besides we can argue Moore law is still OK, dennard scaling is gone and with it the performance boost, as alluded subtly. Link article: http://science.sciencemag.org/content/354/6308/99.full

A free software tool that could revolutionize the drone industry to design and build your own drone/aircraft/fighter with a 3-D online software that generates aerodynamic information (maybe optimization also) about your own design.

A new class of exotic materials could find its way into next-generation technologies that efficiently convert waste heat into electrical current according to new research. Both the exotic materials and the means by which they generate electricity rely on a hybrid of advanced concepts-including string theory combined with black holes combined with cutting-edge condensed matter physics.

Sounds spooky
