Broad scientists have invented also powerful new tools that allow researchers to precisely manipulate the genome and measure the millions of complex chemical interactions within cells.
In the spirit of the Human genome Project the Broad makes its genomic data freely available to researchers around the world.
They plan to pioneer cutting-edge techniques such as genome editing which allows them to precisely introduce any mutations they choose.

Researchers have copied this cellular system to create gene-editing complexes that include a DNA-cutting enzyme called Cas9 bound to a short RNA guide strand that is programmed to bind to a specific genome sequence telling Cas9 where to make its cut.

So what we can do is take that genome-editing tool and target anything we want.
Once these genome-editing techniques were mastered the researchers then had to figure out ways to deliver the modified CRISPRS to the bacteria.

By tweaking the genomes of these viruses, known as bacteriophages, researchers hope to customize them to target any type of pathogenic bacteria.
Also, each family of bacteriophages can have a different genome organization and life cycle, making it difficult to engineer them
the researchers combed through databases of phage genomes looking for sequences that appear to code for the key tail fiber section, known as gp17.
Existing techniques for editing viral genomes are fairly laborious so the researchers came up with an efficient approach in
which they insert the phage genome into a yeast cell, where it exists as an rtificial chromosomeseparate from the yeast cell own genome.
During this process the researchers can easily swap genes in and out of the phage genome. nce we had that method,
it allowed us very easily to identify the genes that code for the tails and engineer them or swap them in and out from other phages,
#New system for human genome editing has potential to increase power and precision of genome engineering A team including the scientist who first harnessed the CRISPR-Cas9 system for mammalian genome editing has identified now a different CRISPR system with the potential for even simpler and more precise genome engineering.

This could be an advantage in targeting some genomes, such as in the malaria parasite as well as in humans. he unexpected properties of Cpf1 and more precise editing open the door to all sorts of applications,

But pediatricians typically can scan an infant entire genome and analyze it for clues quickly enough to make a difference in the baby treatment.
and analyze the entire genome of a critically ill infant to find a diagnosis that can significantly alter the course of treatment.
In a new study published in Genome Medicine, pediatricians explained how hardware and software specialized for genetic analysis can provide such fast and lifesaving information.
The key piece of technology: A processor from the company Edico Genome that designed to handle the big data of genetics.
Lead researcher Stephen Kingsmore, a pediatrician and genomics expert at Children Mercy Hospital in Kansas city, explains that doctors typically run targeted genetic tests for specific diseases
Such tests check a few specific spots on the genome, looking for disease-causing mutations. But with more than 8000 possible genetic diseases, such tests eren really relevant to clinical care, he tells IEEE Spectrum.
Whole-genome sequencing is a different matter entirely. These scans check for mutations at each of the 3. 2 billion locations on the human genome.
Remarkably while it took $3 billion to sequence the first human genome, it can now be done for about $1000 a pop.
That cheap enough to make economic sense in medical emergencies, like those encountered in a neonatal intensive care unit.

the researchers had a file listing all the mutations in a sick baby genome. After that, Kingsmore team used in-house software to search through the mutations for those associated with a disease that matched the baby symptoms.
In a prior study, Kingsmore team used whole-genome sequencing for 35 sick infants, and diagnosed a genetic disease in 20 of those babies.
In other cases, the genome scan allowed doctors to rule out diseases, which Kingsmore says can be equally valuable. octor always worry:

New CRISPR-Cas9 strategy edits genes 2 ways The CRISPR-Cas9 system has been in the limelight mainly as a revolutionary genome engineering tool used to modify specific gene sequences within the vast sea of an organism
genome engineering and gene regulation, are initiated with a common step: the Cas9 protein is recruited to targeted genes by the so-called matching sequences of"GUIDE RNA"that help Cas9 latch on to specific sequences of DNA in a given genome.
But until now, genome engineering and gene regulation required different variants of the Cas9 protein; while the former task hinges on Cas9's innate DNA-cleaving activity,
the latter has been achieved by engineered Cas9 variants that have had their DNA-cleaving"fangs"removed, but still retain their ability to latch onto a specific genomic target.
