Science's Favorite Deep-Sea Explorer Gets High-Tech Upgrades | WIRED - 2 views

  •  
    Alvin, the only deep-diving manned submersible used for science has been upgraded, allowing scientists to explore for the 1st time the depth of the oceans down to 6500m bsl.

Programmable biological circuits - 3 views

  •  
    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.

How Building a Black Hole for Interstellar Led to an Amazing Scientific Discovery | WIRED - 2 views

  •  
    Kip Thorne looks into the black hole he helped create and thinks, "Why, of course. That's what it would do." This particular black hole is a simulation of unprecedented accuracy. It appears to spin at nearly the speed of light, dragging bits of the universe along with it.

Graphene drum could store quantum information - 4 views

  •  
    Devices made from resonating graphene "drums" could be used as microwave amplifiers and memory chips in quantum computers. So say researchers at the Kavli Institute of Nanoscience at the Delft University of Technology in the Netherlands, who are the first to demonstrate optomechanical coupling between a mechanical resonator and a superconducting microwave cavity.

Superabsorbing rings could lead to better cameras and solar cells - 2 views

  •  
    Rings of excited atoms that harness a quantum effect to absorb light at an enhanced rate could be used in future technologies such as highly sensitive cameras, solar cells and systems for optical power transmission.

    A nice GPU-based framework that is basically an emulator of the brain of the fruit fly. If you need a fruit fly brain - here it comes!

Hey There Little Electron, Why Won't You Tell Me Where You Came From? - 2 views

  •  
    A nice article explaining the principle of quantum superposition from the double slits experience. Nothing new here but still interesting to read :)

    I myself am quite a big fan of the one-electron universe paradigm :)))
    And of the cat cannon:

The Highlight of the Scientific Calendar, 2014 - 7 views

    It's out there for TWO days and no one has posted it here yet? What's happening to the ACT...

    In any case, yet-another-year-ACT-didn't-make-it... Better luck next time.

    read them when they came out - as probably 90% of ACTers but did not see any of them worth posting ...

Practical Electrostatic Motor(?) - 3 views

    Apparently a spin-off company of the University of Wisconsin is developing non-magnetic motors. Maybe this could be useful for reaction wheels etc. on satellites that monitor the Earth's magnetic field... (preventing magnetic interference with sensors)

Rocks Made of Plastic Found on Hawaiian Beach - 1 views

  •  
    Plastic may be with us a lot longer than we thought. In addition to clogging up landfills and becoming trapped in Arctic ice, some of it is turning into stone. Scientists say a new type of rock cobbled together from plastic, volcanic rock, beach sand, seashells, and corals has begun forming on the shores of Hawaii.

Direct brain-to-brain communication demonstrated in human subjects -- ScienceDaily - 2 views

  •  
    In a first-of-its-kind study, an international team of neuroscientists and robotics engineers has demonstrated the viability of direct brain-to-brain communication in humans.
  •  
    Was just about to post it... :) It seems after transferring the EEG signals of one person, converting it to bits and stimulating some brain activity using magnetic stimulation (TMS) the receiving person actually sees 'flashes of light' in their peripheral vision. So its using your vision sense to get the information across. Would it not be better to try to see if you can generate some kind of signal in the part of your brain that is connected to 'hearing'? Or would this be me thinking too naive?
  •  
    "transferring the EEG signals of one person, converting it to bits and stimulating some brain activity using magnetic stimulation (TMS)"

    How is this "direct"?

Entangled photons make a picture from a paradox - 3 views

  •  
    Physicists have devised a way to take pictures using light that has not interacted with the object being photographed. This form of imaging uses pairs of photons, twins that are 'entangled' in such a way that the quantum state of one is inextricably linked to the other.

Integral catches dead star exploding in a blaze of glory - 1 views

    Astronomers using ESA's Integral gamma-ray observatory have demonstrated beyond doubt that dead stars known as white dwarfs can reignite and explode as supernovae. The finding came after the unique signature of gamma rays from the radioactive elements created in one of these ex...

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

    Give the Ubermancycle a try?
  • ...4 more comments...
  •  
    I was into this some time ago and found a documentary in which they performed an experiment on a guy.
    Long story short, it didn't work that good. He was semi-lucid all the time and his mental performance dropped.

    Perhaps it is possible to survive like this for months, but if your goal is to maximize your daily output, you will not gain extra work hours due to being 3/4 conscious most of the time.

    EDIT: Not related to the documentary I mentioned but some first hand stories: http://www.reddit.com/r/IAmA/comments/co5t9/i_attempted_polyphasic_sleep_for_a_documentary_ama/c0tza1e
  •  
    I also heard about it. At the moment, I am on some sort of bi-phasic sleep and I am not feeling more tired than with the monophasic one (while sleeping effectively less right now).
  •  
    If it exists, there's an xkcd about it: http://xkcd.com/320/
    Actually the schedule proposed there is quite useful if you're into this whole Friday / Saturday night thing..
  •  
    I don't see why it wouldn't work if you manage to detach yourself from the cycardian input. As in never ever see sun and daylight :))
  •  
    > As in never ever see sun and daylight :))

    Like in the Netherlands you mean?

    Tri-phasic sleep rhythm works fine.

Silk protein and chloroplasts for the synthetic leaf - 2 views

  •  
    Royal College of Art's Innovation Design Engineering course in collaboration with Tufts University silk lab. Not as good as it sounds as it does not fully mimic the photosynthesis equation (spare C, H atoms)
  •  
    Interesting stuff and I guess it does not need to fully mimic photosynthesis in the end. As long as oxygen can be produced from CO2 and water that would be great enough. Though the carbon has to be deposited somewhere (in some form) and I wonder how one could extract this efficiently. Maybe it can even serve some purpose (as the sugars are doing for the plant)
