    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.
  • Thijs Versloot on 25 Mar 14
     
    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 :)

  • "Think of it as rapid prototyping in biology--we make the part, test it, and then expand on it," says Reshma Shetty, one of the company's cofounders. "You can spend more time thinking about the design, rather than doing the grunt work of making DNA." A very simple project, such as assembling two pieces of DNA, might cost $100, with prices increasing from there.

    Whether society embraces face recognition on a larger scale will ultimately depend on how legislators, companies and consumers resolve the argument about its singularity. Is faceprinting as innocuous as photography, an activity that people may freely perform? Or is a faceprint a unique indicator, like a fingerprint or a DNA sequence, that should require a person's active consent before it can be collected, matched, shared or sold?

    Dr. Atick is firmly in the second camp.

    A frog study provides the strongest evidence yet that a father's lifestyle may affect the next generation, via chemical tags that change gene activity SPERM pass on more than just their DNA. Chemical switches attached to the genomes of sperm - known as epigenetic tags - have been shown to alter the next generation for the first time.

    "scientists at Harvard University say they've modified the CRISPR method so it can be used to effectively reverse mutations involving changes in one letter of the genetic code. That's important because two-thirds of genetic illness in humans involve mutations where there's a change in a single letter."

Maybe, next work for the Molecular Engineering RF?
