The Chinese researcher who stunned and alarmed the international scientific community with the announcement that he had created the world’s first gene-edited babies has been sentenced to three years in prison by a court in China.

He Jiankui sparked a bioethical crisis last year when he claimed to have edited the DNA of human embryos, resulting in the birth of twins called Lulu and Nana as well as a possible third pregnancy. The gene editing, which was aimed at making the children immune to HIV, was excoriated by many scientists as a reckless experiment on human subjects that violated basic ethical principles.

UN approves declaration banning all forms of human cloning – UN thông qua tuyên bố cấm mọi hình thức nhân bản vô tính người, năm 2005

UN.org

8 March 2005 –The United Nations General Assembly today approved a non-binding declaration calling on all UN Member States to ban all forms of human cloning, including cloning for medical treatment, as incompatible with human dignity and the protection of human life.

By a vote of 84 in favour, 34 against and 37 abstaining, with 36 absent, the Assembly acted on the recommendation of its Legal, or Sixth, Committee to adopt the text, called the United Nations Declaration on Human Cloning. But some delegates said they opposed banning therapeutic cloning.

The Declaration, negotiated by a Working Group last month, also banned “genetic engineering techniques that may be contrary to human dignity.” It called on States “to prevent the exploitation of women in the application of life sciences” and “to protect adequately human life in the application of life sciences.” Tiếp tục đọc “UN approves declaration banning all forms of human cloning – UN thông qua tuyên bố cấm mọi hình thức nhân bản vô tính người, năm 2005”

Chinese scientists break key barrier by cloning monkeys

LONDON (Reuters) – Chinese scientists have cloned monkeys using the same technique that produced Dolly the sheep two decades ago, breaking a technical barrier that could open the door to copying humans.

  Zhong Zhong and Hua Hua, two identical long-tailed macaques, were born eight and six weeks ago, making them the first primates — the order of mammals that includes monkeys, apes and humans — to be cloned from a non-embryonic cell.

Nature – Genome editing uses enzymes that are targeted to sequences of DNA to make cuts. These cuts are then repaired by the cell’s machinery. This technology allows scientists to disrupt or modify genes with unprecedented precision. By Amy Maxmen, infographic by Denis Mallet.

Double-stranded break

All three of the main genome-editing tools (ZFNs, TALENs and CRISPR–Cas9) create a break across both strands of DNA at a specific location, which is repaired in one of two ways to either ‘knock out’ or ‘knock in’ a gene.
