Where Life Meets Light: Bio-Inspired Photonics - 0 views

  •  
    Octopus and optoelectronics camouflage, light bugs and LEDs, or spider webs and touch screens, ... a whole cool bunch of biomimetic stuff
  •  
    See also the referred work "Light-extraction enhancement for light-emitting diodes: a firefly-inspired structure refined by the genetic algorithm" - quite cool!

Medical Xpress: Newly discovered hormone mimics the effects of exercise - 0 views

  •  
    "Hormones are molecules that act as the body's signals, triggering various physiological responses. The newly discovered hormone, dubbed "MOTS-c," primarily targets muscle tissue, where it restores insulin sensitivity, counteracting diet-induced and age-dependent insulin resistance."

    Good news for long distance space travelers?

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.

    very nice!!!

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.

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 ...

    I think e.g. de Tommaso et al. results have application in almost any business, ESA notwithstanding, in terms of implications for optimal office decor...
