Nature Optics: Super vision - 6 views

  •  
    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.

Octopus robot makes waves with ultra-fast propulsion - 2 views

  •  
    Technology/Robotics Scientists have developed an octopus-like robot, which can zoom through water with ultra-fast propulsion and acceleration never before seen in man-made underwater vehicles. Most fast aquatic animals are sleek and slender to help them move easily through the water but cephalopods, such as the octopus, are capable of high-speed escapes by filling their bodies with water and then quickly expelling it to dart away.

PLOS Computational Biology: Ten Simple Rules for Organizing an Unconference - 1 views

  •  
    For future reference...

    At the same time, a crowdsourced article:
    "We began the crowdsourcing by collecting a list of possible rules for the article via a git-controlled repository"
    SVN would be so 2000-ish...

Meet the electric life forms that live on pure energy - 3 views

  •  
    Unlike any other living thing on Earth, electric bacteria use energy in its purest form - naked electricity in the shape of electrons harvested from rocks and metals. We already knew about two types, Shewanella and Geobacter. Now, biologists are showing that they can entice many more out of rocks and marine mud by tempting them with a bit of electrical juice. Experiments growing bacteria on battery electrodes demonstrate that these novel, mind-boggling forms of life are essentially eating and excreting electricity.

Mystery of where Earth's water came from deepens: Comet water is different - 2 views

  •  
    "Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind."

Brain's reaction to virtual reality should prompt further study, suggests new research - 2 views

  •  
    "Neuroscience UCLA neurophysicists have found that space-mapping neurons in the brain react differently to virtual reality than they do to real-world environments. Their findings could be significant for people who use virtual reality for gaming, military, commercial, scientific or other purposes."

    I wonder if we are doing it wrong with the airplane pilot simulators...

Brain decoder can eavesdrop on your inner voice - 4 views

  •  
    "As you read this, your neurons are firing - that brain activity can now be decoded to reveal the silent words in your head TALKING to yourself used to be a strictly private pastime. That's no longer the case - researchers have eavesdropped on our internal monologue for the first time. The achievement is a step towards helping people who cannot physically speak communicate with the outside world."

    Or alternatively, a step towards snooping into individuals' privacy.

    Soon we'll be able to see movies about our dreams!

    Only if you are willing to have a chip implanted into/onto your brain though ^^

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.

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"?

Neural Networks (!) in OLCI - ocean colour sensor onboard Sentinel 3 - 3 views

  •  
    Not easily digestible piece of esa document, but to prove Paul's point.

    And yes, they have already planned to train neural networks on a database of different water types, so that the satellite figures out from the combined retrieval of backscattering and absorption = f(λ) which type of water it is looking at. Type of water relates to οptical clarity of the water, a variable called turbidity.

    We could do this as well for mapping iron fertilization locations if we find its spectral signature. Lab time?????

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
