gene editing

By Jonathan Latham, PhD and Allison Wilson, PhD Gene-editing is seen by many as the ultimate in precision breeding. Polled cattle, whose horns have been genetically removed, have been presented as exemplars of this–a socially ...

Crops produced with newer gene-editing technologies would only be subject to special oversight under the proposed rule if they posed a risk as plant pests.

Chinese scientists have used gene editing to make the brains of monkeys more human-like by editing the human version of a gene known as ‘MCPH1’ into the macaques. The gene-hacked monkeys showed better reaction times and improved short-term memories.

The Chinese scientist who announced to the world in November 2018 that he had created a pair of gene-edited twin girls could face the death penalty for corruption and bribery charges, a British geneticist fears.

Gene editing has the potential to save lives and prevent devastating diseases, but the technology is still new and the ramifications of such experiments remain largely unknown. So, when a patient’s DNA has been edited using CRISPR-Cas9, researchers keep a close eye on them to track their progress and any problems that may arise.  Or, at least, they’re supposed to. That has not been happening in China.

Following the news that a set of gene-edited twin girls had been born in China in November, the World Health Organization (WHO) announced that it was creating a working group to study gene-editing and the many ethical, social, and safety issues surrounding the process.
The panel’s job will be to develop “agreed norms and standards for the governance of human gene-editing,” the WHO said.
Dr. Tedros Adhanom Ghebreyesus, the WHO’s director-general, warned of the potential for “unintended consequences” of gene-editing during a conference on December 4th.

Just days after a Chinese scientist announced the birth of the world’s first gene-edited babies and a possible 2nd pregnancy, the Chinese government ordered a halt to the highly controversial experiments.

A researcher in China claims to have created the world’s first gene-edited babies, sparking deep discussion, along with some harsh criticisms and outrage among some of the world’s leading scientists.
The highly-controversial news that a set of twin girls was born in November with genetically altered DNA broke on November 26. The girls’ DNA was edited using a powerful new tool with the capacity to rewrite the human genome, known as CRISPR-Cas9.

What about unintended consequences? The CRISPR technique is simple, raising the fear that the technology will be used by ignorant and unethical people. Scientists worry that once a species is modified, it is changed forever.
