"Without the relevant data for reasoning about the state of AI technology, we are essentially "flying blind" in our conversations and decision-making related to AI [...] The AI Index is an initiative to track, collate, distill and visualize data relating to artificial intelligence. "

I'm afraid I take some issue with this rather glorious title. I've only skimmed this paper but looking at the experimental details, their 'imagined universes' comprise of a ball confined in a 2D space as well as a double pendulum. Work along this area is nothing new - it's known in the control community as Inverse Reinforcement Learning - learning dynamics of some system from demonstration trajectories. The paper title ('Toward an AI Physicist for Unsupervised Learning') is more moderate so yet again the issue is how AI is reported in the media...

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!)

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

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

Pretty cool this was never spotted before!!

no cutting-edge space-related science, but important anyways

The EFF communicate is actually quite inaccurate. This is disappointing from the EFF, though for some part, it is due to the communication from the researchers who "discovered" the attack. PGP itself is not broken, but rather some implementations on some email clients (notably Enigmail, though it was patched several months ago). See https://protonmail.com/blog/pgp-vulnerability-efail/ On the other hand, if you are very keen on security, there is an XSS attack reported on Signal, so… https://thehackernews.com/2018/05/signal-messenger-code-injection.html The *good* recommendation here is actually rather to keep your software stack up to date (surprising, no?) and keep encrypting your emails.

Loss of connectivity in the multisensory integration cortical areas after short term microgravity experience, which could explain astronauts decrease of performance in sensorimotor tasks and spatial working memory. However, the effect should wear off after a few days in microgravity and after adaptation to incongruent vestibular information. ISS experiment needed...

"...the European Commission announced in 2016 that it was investing one billion euros in a research effort known as the Quantum Technology Flagship. The goal for this project is to develop four technologies: quantum communication, quantum simulation, quantum computing, and quantum sensing. After almost two years, how is it going?" arxiv link to the actual report: http://arxiv.org/abs/1712.03773

" The goal of the APT program is to control and direct plant physiology to detect chemical, biological, radiological, and/or nuclear threats, as well as electromagnetic signals. " Now that is an advanced concept...

and look at this exceptional insight: "plants are easily deployed, self-powering, and ubiquitous in the environment, and the combination of these native abilities with specifically engineered sense-and-report traits will produce sensors occupying new and unique operational spaces" :-)

38 degree core body temp in microgravity stabilised after 2 months - due to reduced conv. heat transfer+evaporation https://www.nature.com/articles/s41598-017-15560-w

so that's hypopyrexia (augmented concentrations of interleukin-1 receptor antagonist) AND hypothermia (convection/evaportation)? what puzzles me is that temperatures take so long to return to baseline after astronauts return to earth.

... related to the new mathematical proof of emergence of structures in random graphs.
