Clustered regularly-interspaced short palindromic repeats (abbreviated as CRISPR, pronounced crisper) are segments of prokaryotic DNA containing short repetitions of base sequences. Each repetition is followed by short segments of "spacer DNA" from previous exposures to a bacterial virus or plasmid.
The CRISPR/Cas system is a prokaryotic immune system that confers resistance to foreign genetic elements such as plasmids and phages, and provides a form of acquired immunity. CRISPR spacers recognize and cut these exogenous genetic elements in a manner analogous to RNA interference in eukaryotic organisms. CRISPRs are found in approximately 40% of sequenced bacteria genomes and 90% of sequenced archaea.
The CRISPR interference technique has enormous potential application, including altering the germline of humans, animals and other organisms, and modifying the genes of food crops. By delivering the Cas9 protein and appropriate guide RNAs into a cell, the organism's genome can be cut at any desired location. CRISPRs have been used in concert with specific endonuclease enzymes for genome editing and gene regulation in species throughout the tree of life. Ethical concerns have been expressed about this nascent biotechnology and the prospect of editing the human germline.
Designer babies, the end of diseases, genetically modified humans that never age. Outrageous things that used to be science fiction are suddenly becoming reality. The only thing we know for sure is that things will change irreversibly.

Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases … but could also be used to create so-called "designer babies." Doudna reviews how CRISPR-Cas9 works — and asks the scientific community to pause and discuss the ethics of this new tool.

This animation depicts the CRISPR-Cas9 method for genome editing – a powerful new technology with many applications in biomedical research, including the potential to treat human genetic disease. Feng Zhang, a leader in the development of this technology, is a faculty member at MIT, an investigator at the McGovern Institute for Brain Research, and a core member of the Broad Institute. Further information can be found on Prof. Zhang’s website at http://zlab.mit.edu . Images and footage courtesy of Sputnik Animation, the Broad Institute of MIT and Harvard, Justin Knight and pond5.
Should we bring back the wooly mammoth? Or edit a human embryo? Or wipe out an entire species that we consider harmful? The genome-editing technology CRISPR has made extraordinary questions like these legitimate — but how does it work? Scientist and community lab advocate Ellen Jorgensen is on a mission to explain the myths and realities of CRISPR, hype-free, to the non-scientists among us.

http://www.ibiology.org/ibiomagazine/jennifer-doudna-genome-engineering-with-crispr-cas9-birth-of-a-breakthrough-technology.html Talk Overview: Jennifer Doudna tells the story of how studying the way bacteria fight viral infection turned into a genomic engineering technology that has transformed molecular biology research. In 2013, Doudna and her colleagues developed the CRISPR-Cas9 gene expression system that, when introduced into animal cells, makes site-specific changes to intact genomes. CRISPR-Cas9 is more precise, more efficient, and less expensive than other genome editing tools and, as a result, has facilitated a wide range of studies that were previously unachievable.

I don't think so
Lights out, bad deal, you don't know how I feel
That's right, get real, don't under estimate me now
Your sick ideals don't have no part in me
Get lost, be gone, you hope that we'll go on
But I don't think so

But I don't think so
This will only happen in your head
Cause I don't think so
Tough luck, you loose, I won't play by your rules
Too much, too soon, don't bother me with your do's and don't's
You're stuck, confused and ancient minded too
You pushed too far, now I got news for you
I don't think so
You want me to be your bitch in bed
But I don't think so
You want me to love you 'til I'm dead
But I don't think so
You want me to make your food, clean up your mess
But I don't think so
This will only happen in your head
Cause I don't think so
You want me to love you 'til I'm dead
This will only happen in your head
W hy do you mess up what we have
I don't think so
You want me to be your bitch in bed
But I don't think so
You want me to love you 'til I'm dead
But I don't think so
You want me to make your food, clean up your mess
