Scientists Urge Caution in Using New “Cut and Splice” Technology to Treat Genetic Disease

Published

By Robert Sanders, UC Berkeley News

A group of 18 scientists and ethicists are warning that a revolutionary new tool to cut and splice DNA should be used cautiously when attempting to fix human genetic disease, and strongly discouraged any attempts at making changes to the human genome that could be passed on to offspring.

Among the authors of this warning is Jennifer Doudna, the co-inventor of the technology, called CRISPR-Cas9, which is driving a new interest in gene therapy, or “genome engineering.”

She and colleagues co-authored a perspective piece that appears in the March 20 issue of Science, based on discussions at a meeting that took place in Napa on Jan. 24. The same issue of Science features a collection of recent research papers, commentary and news articles on CRISPR and its implications.

“Given the speed with which the genome engineering field is evolving, our group concluded that there is an urgent need for open discussion of the merits and risks of human genome modification by a broad cohort of scientists, clinicians, social scientists, the general public and relevant public entities and interest groups,” the authors wrote.

Doudna, director of UC Berkeley’s Innovative Genomics Initiative, was joined by five current and two former UC Berkeley scientists, plus David Baltimore, a Nobel laureate and president emeritus of the California Institute of Technology, Stanford Nobelist Paul Berg and eminent scientists from UC San Francisco, Stanford, Harvard and the universities of Wisconsin and Utah. Several of these scientists are currently involved in gene therapy to cure inherited diseases.

Such warnings have been issued numerous times since the dawn of genetic engineering in 1975, but until now the technology to actually fix genetic defects was hard to use.

“However, this limitation has been upended recently by the rapid development and widespread adoption of a simple, inexpensive and remarkably effective genome engineering method known as CRISPR-Cas9,” the scientists wrote. “The simplicity of the CRISPR-Cas9 system enables any researcher with knowledge of molecular biology to modify genomes, making feasible many experiments that were previously difficult or impossible to conduct.”

Scientists today are changing DNA sequences to correct genetic defects in animals as well as cultured tissues generated from stem cells, strategies that could eventually be used to treat human disease. The technology can also be used to engineer animals with genetic diseases mimicking human disease, which could lead to new insights into previously enigmatic disorders.

The CRISPR-Cas9 tool is still being refined to ensure that genetic changes are precisely targeted, Doudna said. Nevertheless, the authors met “… to initiate an informed discussion of the uses of genome engineering technology, and to identify proactively those areas where current action is essential to prepare for future developments. We recommend taking immediate steps toward ensuring that the application of genome engineering technology is performed safely and ethically.”

Of particular concern are changes to genes in “germline cells” – sperm and egg – that can be passed on to offspring. Even a germline modification that eliminated a genetic disease that has plagued a family for generations could have unintended consequences, given current limitations on our knowledge of human genetics.

“We believe that initiating these fascinating and challenging discussions now will optimize the decisions society will make at the advent of a new era in biology and genetics,” the authors concluded.

The UC Berkeley authors are Michael Botchan, a professor of molecular and cell biology and IGI co-director; G. Steven Martin, dean of biological sciences and a professor of molecular and cell biology; chemistry researcher Samuel Sternberg; IGI scientific director Jacob Corn; and IGI program director Marsha Fenner. Edward Penhoet, a former dean of the UC Berkeley School of Public Health, and Martin Jinek, a co-inventor of CRISPR now at the University of Zurich, also signed the commentary.

UC Berkeley Named Top Public University in the U.S. and No. 7 in the World by ‘U.S. News’

Berkeley has been consistently awarded the distinction of the U.S.’s top public university since the Best Global Universities list was first published in 2014. “A strong position in the Best Global Universities rankings recognizes a school’s profound commitment to world-class research and cross-border academic excellence,” said LaMont Jones, managing editor for education at U.S. News.

The 2026 Best Global Universities rankings evaluated 2,250 research institutions from more than 100 countries

By Lila Thulin

U.S. News & World Report has ranked UC Berkeley No. 7 in its 2026 list of the best global universities, which assesses more than 2,250 research institutions worldwide.

Berkeley also claimed the honor of top public university in the U.S.

Released on Monday, the list evaluates universities from more than 100 countries on 13 metrics such as global and research reputation (as reported by academics and peers) and number of highly cited scholarly papers.

Berkeley has been consistently awarded the distinction of the U.S.’s top public university since the Best Global Universities list was first published in 2014.

“A strong position in the Best Global Universities rankings recognizes a school’s profound commitment to world-class research and cross-border academic excellence,” said LaMont Jones, managing editor for education at U.S. News.

The rankings also assess a university’s strength in various subject areas; these assessments are separate from U.S. News’ 2026 Best Graduate Programs rankings released in April.

This year, Berkeley was named in the top three nationally in seven subject areas – environment/ecology, ecology, water resources, physics, computer science, chemistry, and engineering – and in the top five for a total of 17 subjects. Subject rankings are based heavily on scholarly publications and citations as well as reputation.

In September, U.S. News also released its 2026 Best Colleges list, in which Berkeley was also named the No. 1 public institution among American universities.

That honor joins other accolades judging campus to be the best public university in the country, such as those from ForbesThe Wall Street Journal and Times Higher Education.

Hundreds of members of Delta Sigma Theta Sorority, Inc., and their guests gathered at the Martin Luther King Jr. Student Union at the University of California, Berkeley, to mark the 100th anniversary of the sorority’s Farwest Region.

The region was established in 1925 under the leadership of Vivian Osborne Marsh, who became its first Regional Director. Marsh was a pioneering scholar and civic leader, earning recognition as the first Black woman to receive both a bachelor’s and a master’s degree in anthropology from UC Berkeley.

Marsh went on to serve as Delta Sigma Theta’s 7th National President, where she launched the sorority’s National Library Project to expand access to books in underserved Black communities in the South. During her presidency, the organization also became a prominent voice in the civil rights movement, lobbying Congress to pass anti-lynching legislation.

Bak in the Bay Area, Marsh devoted her career to advancing educational opportunities, mentoring young people, and strengthening community life. That commitment continues to shape the region, which supports initiatives in education, social justice, and economic development. Current projects include raising scholarship funds for students at Historically Black Colleges and Universities, voter education campaigns, and health and wellness programs.

A century after its founding, the Farwest Region of Delta Sigma Theta remains active across California and other western states, carrying forward Marsh’s vision of service and advocacy.

On Labor Day weekend two of the world’s most celebrated musicians and cultural ambassadors, Grammy Award–winning vocalist Angélique Kidjo and legendary cellist Yo-Yo Ma join forces for an evening of music, history, and cultural dialogue at UC Berkeley’s historic Hearst Greek Theatre.

On Saturday, Aug. 30, the pair will debut the Bay Area premiere of Sarabande Africaine, joined by pianist Thierry Vaton, percussionist David Donatien, and special guest Sinkane. The program illuminates centuries of musical interplay between African traditions and Western classical forms, using the Baroque sarabande dance, and its African ancestor, the Congolese spirit dance Zarabanda, as a gateway to exploring the deep, interconnected roots of global music.

Both Kidjo and Ma have built careers not only as great performers but as passionate advocates for cultural understanding. Sarabande Africaine is as much a conversation about shared heritage as it is a musical performance, blending genres, geographies, and histories.

“Every day there are moments when all of us can feel we are on the inside of something and also when we feel we are on the outside of something,” said Yo-Yo Ma.  “To be able to understand both at the same time and oscillate between the two gives us a larger perspective on the world.”

“If your mind is open, and there is no fear, it’s easier to listen, and to question yourself,” said Kidjo.

The upcoming performance is presented within Cal Performances’ Illuminations: “Exile & Sanctuary” series for the 2025–26 season. The production explores exile as more than just physical displacement, but a disruption in identity and belonging, while sanctuary represents both refuge and the creative space where new connections and communities can take shape.

Cal Performances’ Illuminations bridges performances with UC Berkeley’s academic research, pairing the arts with conversations about urgent global issues.

Kidjo’s continued partnership with Cal Performances includes her 2021–22 artist-in-residence, premiering her music-theater work Yemandja, set in 19th-century West Africa during the transatlantic slave trade.

She also participated in the Bias in Our Algorithms and Society panel alongside campus leaders like Jennifer Chayes, and joined the Black Studies Collaboratory for a dialogue on music, diaspora, and the world.

She has since returned to Berkeley for multiple performances, most recently in 2024 at Zellerbach Hall.

Yo-Yo Ma’s history with Cal Performances spans decades, beginning in 1997. One notable project includes the 2018 performance of Bach’s complete cello suites at the Greek Theatre, a testament to his devotion to creating “transformative concert experiences in iconic spaces.”
