In addition to CRISPR research, the IGI works to advance public understanding of CRISPR and genome engineering and guide the ethical use of these technologies. Free public resources include: CRISPRpedia — a free textbook-style resource for learning about the biology, applications, and ethics of CRISPR and genome editing, with chapters edited ...
On 26 November 2018, The CRISPR Journal published ahead of print an article by He, Ryan Ferrell, Chen Yuanlin, Qin Jinzhou, and Chen Yangran in which the authors justified the ethical use of CRISPR gene editing in humans. [74] As the news of CRISPR babies broke out, the editors reexamined the paper and retracted it on 28 December, announcing:
Moral judgments are empirically based and entail evaluating prospective risk-benefit ratios particularly in the field of biomedicine. The technology of CRISPR genome editing raises ethical questions for several reasons. To be more specific, concerns exist regarding the capabilities and technological constraints of CRISPR technology.
The major hurdles coming in the clinical applications are ethical issues and the transport system to the target site. As the units of CRISPR system taken from bacteria, when they are transferred to host cells it produces an immune response against them. Physical, chemical, viral vectors are used as vehicles to deliver the complex into the host.
Fast-paced developments in the CRISPR-Cas9 gene editing technology has increased both the concerns and relevance of this ethical controversy as it has become more popularly used. [19] [20] The scientific community recommends continued evaluation of risks and benefits of utilizing genetically modified organisms in everyday life. [21]
CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.
Off-target genome editing refers to nonspecific and unintended genetic modifications that can arise through the use of engineered nuclease technologies such as: clustered, regularly interspaced, short palindromic repeats ()-Cas9, transcription activator-like effector nucleases (), meganucleases, and zinc finger nucleases (ZFN).

The eggs, reportedly from several voluntary donors, were from Hwang's two researchers, a fact which Hwang denied. The ethical issues made Schatten immediately break his ties with Hwang. In December 2005, a whistleblower informed Science of reuse of the same data. As the journal probed in, it was revealed that there was a lot more data ...
