New Method Confirms Humans and Neandertals Interbred - 0 views

  •  
    Looks like the genetic evidence for the interbreding of homo sapiens and homo neanderthalensis becomes significant.
  •  
    "Humans and Neanderthals interbred" - isn't that a bit weird since we call the result of the interbreeding "Humans" as well? This is a bit like saying "Ligers and Tigers interbred".

    Yes, you read correctly. Apply current to your brain to get smarter. Ariadna anyone?

Genetic mugshot recreates faces from nothing but DNA - 3 views

  •  
    By just getting a DNA footprint of a person scientists (and soon police) can produce an image of the person's face. Check out the pictures!

    wow thats pretty amazing! Ok, the pictures are not great (mainly due to skin surface, baggy eyes, zits I guess) but considering its only from DNA it is pretty close already. That will help crime scene investigations greatly, whether positively or negatively.
  •  
    Ouch! You're pretty harsh on that lady... :-o
  •  
    should try it the other way around, deduce the DNA from facial features. That would be even cooler.
  •  
    Well actually, they did something like that as they searched for common DNA patterns in people that had similar facial features. With a large enough dataset that could provide already 24 DNA tracers that could used reliably for prediction. Imagine if you had even more data available, who needs a model then... just let the NN do it :)

Bionic plants: Nanotechnology could turn shrubbery into supercharged energy producers -... - 1 views

  •  
    Plants have many valuable functions: They provide food and fuel, release the oxygen that we breathe, and add beauty to our surroundings. Now, researchers wants to make plants even more useful by augmenting them with nanomaterials that could enhance their energy production and give them completely new functions, such as monitoring environmental pollutants.

Here come gravitational waves - 3 views

    Here you go. You can now scrap Lisa altogether.
    Who's going to tell Pacome?

    Awesome and exciting stuff indeed!

    The data pinpoint the time when inflation occurred - about 10E-37 seconds into the Universe's life - and its temperature at the time, corresponding to energies of about 10E16 gigaelectronvolts, says cosmologist Michael Turner of the University of Chicago. That is the same energy at which three of the four fundamental forces of nature - the weak, strong and electromagnetic force - are expected to become indistinguishable from one another in a model known as the grand unified theory.

    I expect more fundamental physics insights to come out of this in the future. A full-sky survey from space may still be an interesting addition to the measurement capabilities, so I would not rule out LISA all together I guess...

Nasa-funded study: industrial civilisation headed for 'irreversible collapse'? - 4 views

  •  
    Sounds relevant. Does ESA need to have a position on this question?
  •  
    This was on Slashdot now, with a link to the paper. It quite an iteresting study actually.

    "The scenarios most closely reflecting the reality of our world today are found in the third group of experiments (see section 5.3), where we introduced economic stratification. Under such conditions, we find that collapse is difficult to avoid."
  •  
    Interesting, but is it new? In general, I would say that history has shown us that it is inevitable that civilisations get replaced by new concepts (much is published about this, read eg Fog of War by Jona Lendering on the struggles between civilisations in ancient history, which have remarkably similar issues as today, yet on a different scale of course).

    "While some members of society might raise the alarm that the system is moving towards an impending collapse and therefore advocate structural changes to society in order to avoid it, Elites and their supporters, who opposed making these changes, could point to the long sustainable trajectory 'so far' in support of doing nothing."

    I guess this bang on it, the ones that can change the system, are not benefitted by doing so, hence enrichment, depletion, short term gain remain and might even accelerate to compensate for the loss in the rest of the system.

World First: 3D Acoustic Cloaking Device | I Fucking Love Science - 1 views

  •  
    Old news... Sante was doing this 10 years ago! And why does their metamaterial look like a pyramid?
  •  
    According to Terry Pratchett pyramids affect the flow of time. Using this, any kind of cloaking device should be trivial.

Did dark matter kill the dinosaurs? : Nature News & Comment - 1 views

  •  
    theoretical physicists... :)

    Read the last sentence of the paper...in this way anyone can publish in nature...just make a good story with little evidence

    Did dark matter kill the dinosaurs?
    The Solar System's periodic passage through a 'dark disk' on the galactic plane could trigger comet bombardments that would cause mass extinctions.
  •  
    Hmm.. right.. then again, this is not an actual journal publication but a news broadcast. But you are right that the name Nature is attached to it so the journal is definitely banking on their acquired status.

    Patterning the glass can make it up to 200 times more resistant to forming cracks

    Also, tornados could be stopped from forming by building 300 m tall, 100 km long walls across the USA:

    Those would also work very well to keep the Kaiju's out..
  •  
    Good point!

Computing with RNA - 0 views

  •  
    After a discussion this morning on robust computing and possible implementations in biological systems I found this really nice result (from 2008) on molecular RNA computers that get assembled within cells and perform simple functions. Of course by having different types of computers within the same cell one could go on to process the output of the other and more complex computations could be executed... Food for thought. :-)

First animals oxygenated the ocean -- ScienceDaily - 0 views

  •  
    Now this is an interesting hypothesis!
    Would make terraforming a bit easier 
  •  
    Having an ocean on Mars would solve so many problems... btw, again this guy? Isabelle take a look at that : Tim Lenton is everywhere, last time he wrote half of our literature references on the tipping points study.

Asteroid break-up captured on film for the first time - 1 views

    Probably related to the former ACT study on asteroid spin-up and the YORP effect.

Sea Sapphire: the Most Beautiful Animal You've Never Heard Of - 2 views

  •  
    this is what I call truly cloaking!...of course only found in and made by nature :)
    (video at the bottom of the page)
  •  
    Definitely beautiful, even psychedelic maybe.. but technically its not really cloaking, you wouldn't call your window a cloaking device right? :)
  •  
    The video looks surreal!

    Very nice new concept for active vibration damping.
    I think this has huge potential for space applications
