    Awesome, they managed. (this is a different deal as the micro ones )

    haha, just what they need in holland ;) anyway this is impressive !
  •  
    really nice - must not be that easy to control, correct?
  •  
    when we tried (http://cas.ensmp.fr/~petit/site-oiseau-np/main.htm good old time :) ) the kinematic and mechanics were the big issues.
  •  
    this looks like a very nice project back in 2005 ...
  •  
    Does it also attack people to capture their fish & chips like those beasts we have here in St. Ives?

Deep drilling on Mars - 0 views

  •  
    The scientific rationale behind it is that at km-depth there could be a) water resources (which could support a biosphere) and b) understand the formation of Mars. I would argue that an efficient drilling (robot) is also valuable for possible developing underground habitation (caves) at some point. This paper mentions two drilling concepts, but we could come up with many more (bio-inspired) probably. Daniel already came up with a nice one.. microwave drilling Also, the NASA InSight probe to Mars in 2016 is using a DLR-designed 'Mole' drill that is designed to reach a depth of... 5 meters

    Doesn't this one fit in nicely with your ablation giant mirror power beaming thing you were working on?
  •  
    In this case I was thinking more about a smaller and controlled digging effort.. not ablating a football field sized hole
  •  
    Nice one! plenty of examples in nature for this

Meet OutRunner: The World's First Remotely Controlled Running Robot - YouTube - 8 views

    the only downside is that you have to launch it before it can run... :)

    Nice idea! Get one? :)
  •  
    Next step : make them get up by themselves after a fall. Then you can envisage to play with them on more rugged terrain :)
  •  
    Hmm.. but how would you make it such that it can stand up? Maybe launch it somehow forward?
  •  
    I can imagine a system with 2 retractable support legs to stand it up and raise it a bit above the floor. Then make it run and retract the legs abruptly.

Light bending material facilitates the search for new particles - 0 views

  •  
    The problem is that the light cone angle has a limit - all particles with high momentum (mass x velocity) generate light cones with the same angle. Hence, these particles are indistinguishable. Now Chalmers researcher Philippe Tassin and his colleagues at the Free University of Brussels have designed a material that manipulates the Cherenkov cone so that also particles with high momentum get a distinct light cone angle too. The work is on the cover of this week's issue of the journal Physical Review Letters ("Controlling Cherenkov Radiation with Transformation-Optical Metamaterials").

OpenBCI - 5 views

  •  
    "The OpenBCI Board is a versatile and affordable analog-to-digital converter that can be used to sample electrical brain activity (EEG), muscle activity (EMG), heart rate (EKG), and more" Perhaps some work or ideas on brainwave analysis would be interesting ? (User interfaces, mood classifier, detection of various alertness levels )

    lets get one? And then link to the Oculus Rift to control it with my brain.. I want to think about running on Mars and then be doing it :)
  •  
    It's not worth it for $400... The chips are seriously nothing special and you can get a lot better for a lot cheaper. I would just get the electrodes and link them to a RPi or an Odroid or something.
  •  
    True, but the selling feature here is that they take care of that stuff and sell it for 400$. Lets say the hardware is 100USD, then an RF-grade person here here has to do the coding, interfacing, testing within roughly (300/16eur/hour) 20 hours to break even and even then the interface is much nicer in their case.

Bacteria Living in 'Cloud Cities' May Control Rain and Snow Patterns : DNews - 1 views

  •  
    Some bacteria can influence the weather. Up high in the sky where clouds form, water droplets condense and ice crystal grow around tiny particles. Typically these particles are dust, pollen, or even soot from a wildfire. But recently scientists have begun to realize that some of these little particles are alive - they are bacteria evolved to create ice or water droplets around themselves. old but might be worth a discussion

Lust in space: Russians lose control of gecko sex satellite | Al Jazeera America - 5 views

  • Lizards were sent into orbit as part of study into effects of weightlessness on sexual intercourse
  • On Thursday, the team behind the research confirmed that the vessel was not responding to commands, potentially leaving the reptiles to their out-of-this-world sexual intercourse while video footage continues to beam down to Earth.
  •  
    I still think, the lizards have evolved at an unexpectedly high rate and have now taken over the satellite...

Filamentous laser beams point to new type of phase transition - applications in weather... - 2 views

  •  
    Filaments of plasma created by a high-powered laser beam undergo a similar type of phase transition as liquid percolating through a porous material - that is the conclusion of physicists in Switzerland. The also describe the application of laser filamentation for directed lightening and encouraged rainfall - Isabelle should come back to take a closer look :p

Wireless 10 kW power transmission - 1 views

  •  
    Mitsubishi Heavy Industries said Friday that it has succeeded in transmitting 10 kW of power through 500 m. An announcement that comes just after JAXA scientists reported one more breakthrough in the quest for Space Solar Power Systems (http://phys.org/news/2015-03-japan-space-scientists-wireless-energy.html). One step closer to Power Generation from Space/
  •  
    from the press release (https://www.mhi-global.com/news/story/1503121879.html) "10 kilowatts (kW) of power was sent from a transmitting unit by microwave. The reception of power was confirmed at a receiver unit located at a distance of 500 meters (m) away by the illumination of LED lights, using part of power transmitted". So 10kW of transmission to light a few efficient LED lights??? In a 2011 report (https://www.mhi-global.com/company/technology/review/pdf/e484/e484017.pdf), MHI estimated this would generate the same electricity output as a 400-megawatt thermal plant - or enough to serve more than 150,000 homes during peak hours. The price? The same as publicly supplied power, according to its calculations. There are no results to boost these claims however. The main work they do now is focused on beam steering control. I guess the real application in mind is more targeted to terrestrial applications, eg wireless highway charging (http://www.bbc.com/future/story/20120312-wireless-highway-to-charge-cars). With the distances so much shorter, leading to much smaller antenna's and rectenna's this makes much more sense to me to develop.

Italy and its TG4 middle ages news chanel - 6 views

  •  
    Its in italian sorry ... but its worth trying to understand ..basically its how an important italian news channel (TG4) gave the rosetta news ... WOW ... middle ages Basically they say ESA spoilt the magic of comets (jesus birth and similar stuff) revealing to the world that it is just a rock and nothing more spending 100 Meuros in the process.
  •  
    A pearl of the italian national news channels. A comet is nothing more than a dusty rock. Wow, brilliant, such level of understanding of what is happening! Can we use the typhoon control or some other project to get rid of them? They're so confused and ignorant that it's not even clear what their point is, apart from "spoiling the magic of comets", which is not the case.

The complete guide to listening to music at work - 3 views

  •  
    Nine out of 10 workers perform better when listening to music, according to a new study that found 88pc of participants produced their most accurate test results and 81pc completed their fastest work when music was playing.
  •  
    There's this website: https://www.focusatwill.com/ , which I used for some time. At some point I even subscribed for the paid version (more tracks, control over "intensity" of music). Unfortunately I realized I work the best in complete silence, which is tricky to get - occasionally I put on the white noise http://simplynoise.com/ which works quite well for me.

NASA Vesta Trek - 2 views

  •  
    NASA Releases Tool Enabling Citizen Scientists to Examine Asteroid Vesta Vesta Trek is a free, web-based application that provides detailed visualizations of Vesta, one of the largest asteroids in our solar system. NASA's Dawn spacecraft studied Vesta from July 2011 to September 2012. Data gathered from multiple instruments aboard Dawn have been compiled into Vesta Trek's user-friendly set of tools, enabling citizen scientists and students to study the asteroid's features. The application includes: -- Interactive maps with the ability to overlay a growing range of data sets including topography, mineralogy, abundance of elements and geology, as well as analysis tools for measuring the diameters, heights and depths of surface features and more. -- 3-D printer-exportable topography so users can print physical models of Vesta's surface. -- Standard keyboard gaming controls to manoever a first-person visualization of "flying" across the surface of the asteroid. "There's nothing like seeing something with your own eyes, but these types of detailed data-visualizations are the next best thing," said Kristen Erickson, Director, Science Engagement and Partnerships at NASA Headquarters in Washington DC.

Nuclear cycler: An incremental approach to the deflection of asteroids - 1 views

  •  
    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.

Dynamic flat lens with metasurface actuated with MEMS - 2 views

  •  
    Great engineering feat from Capasso's idea - an integrated flat lens electrically controlled enabling dynamic beam steering. Reconfigurabilility is the aim. The lens can be used microscope systems, holographic and projection imaging, LIDAR and laser printing. Besides working now on the mid-IR, visible light is the target.

    Heads will fall in ESRIN... And now I know who crashed my computations on sophia ;-) [Edit] A lesson for everyone: look at the file with email passwords and see how many you are able to guess even though they're supposed to be scrambled by removing a middle part... [Edit] And a hilarious quote from the hacker's "about me": "I had another blog, more exactly www.tinkode.baywords.com but I forgot the password, so now I created this one."
  •  
    got the reply from IT security today: they had dealt with apparently the very same day and all under control :-)
  •  
    Well, I wouldn't expect a reply: "all our past emails have been downloaded and sold to NASA" even if that was the case.
  •  
    Of course Marek is right... What matters is the theatre of security, not security itself. Just like in airports :)
