2 women win Nobel Prize in chemistry for gene-editing method

The scientists’ work allows for laser-sharp snips in long strings of DNA, permitting researchers to precisely edit specific genes to remove errors that lead to disease.

“There is enormous power in this genetic tool, which affects us all,” said Claes Gustafsson, chair of the Nobel Committee for Chemistry. “It has not only revolutionized basic science, but also resulted in innovative crops and will lead to groundbreaking new medical treatments.”

“My greatest hope is that it’s used for good, to uncover new mysteries in biology, and to benefit humankind,” said Doudna, who is age 56 and works at the University of California at Berkeley.

But many have cautioned that the technology must be used carefully. In 2018, Chinese scientist He Jiankui revealed he had helped make the world’s first gene-edited babies, to try to engineer resistance to future infection with the AIDS virus. His work was publicly condemned as unsafe human

Two women win Nobel Prize in chemistry for work on CRISPR gene-editing system

The Nobel Prize in chemistry was awarded Wednesday to UC Berkeley biochemist Jennifer A. Doudna and French scientist Emmanuelle Charpentier for their pioneering work on the so-called CRISPR tool for gene editing, a discovery that holds out the possibility of curing genetic diseases.

The Nobel Committee said the two women’s work on developing the CRISPR method of gene editing, likened to an elegant pair of “molecular scissors,” had transformed the life sciences by allowing scientists to target specific sequences on the human genome.

This could, for example, allow doctors to correct the DNA error that causes sickle-cell anemia. It also paves the way for improving plants and livestock by imbuing them with greater disease resistance, and for safer transplants of animal organs

2 women earn Chemistry Nobel Prize for gene-editing tool CRISPR

The 2020 Nobel Prize in chemistry went to two women who developed a gene-editing tool called CRISPR-Cas9, which snips DNA like a pair of molecular scissors.

The technique “has not only revolutionized basic science, but also resulted in innovative crops and will lead to ground-breaking new medical treatments,” Claes Gustafsson, chair of the Nobel Committee for Chemistry, said in a statement. With the ability to deftly slice specific DNA sequences from the genome, scientists can pinpoint the functions of genes; these discoveries both add to our basic understanding of how those genes work and can have practical applications, such as for growing drought- and pest-resistant crops and developing therapies for cancer and genetic disorders. The genetic cut-and-paste system is also being used in new COVID-19 diagnostic tests.

Two women share Nobel chemistry prize for gene-editing discoveries

This year’s Nobel Prize in chemistry has been awarded to Emmanuelle Charpentier of France and Jennifer Doudna of the US for their pioneering work in developing the Crispr gene editing technique that has transformed biology research.

The “genetic scissors” developed by Professors Charpentier and Doudna have had a transformational impact, enabling researchers to change the DNA of animals, plants and microbes far more precisely than older genetic engineering techniques.

“It has not only revolutionised basic science but also resulted in innovative crops and will lead to groundbreaking new medical treatments,” said Claes Gustafsson, chair of the Nobel Committee for Chemistry, on Wednesday.

The chemistry prize has never before been shared by two women. “My wish is that this will provide a positive message to the young girls who would like to follow the path of science, and to show them that women in science can also have an impact through

Two scientists won the Nobel Prize in Chemistry on Wednesday for developing a method of genome editing that is contributing to new cancer therapies and providing a path toward cures for inherited diseases.

France’s Emmanuelle Charpentier and American Jennifer A. Doudna shared the prize awarded by the Royal Swedish Academy of Sciences in Stockholm.

They investigated the immune system of a Streptococcus bacterium and discovered a molecular tool that can be used to make precise incisions in genetic material, making it possible to easily change the code of life, the academy said.

Upon hearing the news of the award, Dr. Charpentier, director of the Max Planck Unit for the Science of Pathogens, Berlin, said she hoped the method of
