University of California, Davis, scientists are teaming up with 新澳门六合彩内幕信息 Berkeley and 新澳门六合彩内幕信息 San Francisco researchers on a $70-million donor-funded initiative that aims in part to cut climate change-causing emissions from cattle by using the genome-editing tool CRISPR on microbes in the cows鈥 gut.
Professor Ermias Kebreab, known for his innovative research using feed additives to reduce methane emissions, and Associate Professor Matthias Hess will collaborate with a world-renowned team at 新澳门六合彩内幕信息 Berkeley: Professors Jennifer Doudna and Jill Banfield. Doudna won the 2020 Nobel Prize in chemistry for her work to develop CRISPR genome-editing technology. Earlier this year, Banfield became the first woman to win the van Leeuwenhoek Medal for her impact on the field of microbiology.
The groundbreaking health and climate initiative will be funded by TED鈥檚 which provides donor support to encourage the world鈥檚 greatest changemakers to dream bigger. Announced today at the TED conference in Vancouver, 鈥淓ngineering the Microbiome with CRISPR to Improve our Climate and Health鈥 is the largest scientific award funded through the project to date.
鈥淭his cutting-edge initiative will harness the University of California鈥檚 research prowess to solve real-world problems in areas that affect us all: sustainability and health,鈥 said University of California President Michael V. Drake. 鈥淚鈥檓 very pleased to see multiple 新澳门六合彩内幕信息 entities working collaboratively to develop and deploy new technology for the public good. I鈥檓 grateful to our philanthropic partners for supporting impactful research that will change the world for the better.鈥
Partnering across the 新澳门六合彩内幕信息
Kebreab, an animal scientist and associate dean of global engagement at the College of Agricultural and Environmental Sciences, and Hess, a microbiologist, will serve as co-principal investigators at 新澳门六合彩内幕信息 Davis to build on their successful work reducing methane emissions in livestock. In 2021, Kebreab gave.
鈥淥ur campuses coming together on a project this big was a very organic process that came from many years of working together,鈥 said Hess. 鈥淒onors are providing us a great opportunity for our team to bring variety of expertise that can benefit many different areas.鈥
Doudna and Banfield will lead . They are combining their expertise to build a new toolkit to address global problems in climate and human health by applying CRISPR genome editing and genome-resolved metagenomics to complex microbial communities known as microbiomes.
Dysfunctions or irregularities in human microbiomes can impact health issues, including asthma. will be led by Professor Sue Lynch, director of the 新澳门六合彩内幕信息SF Benioff Center for Microbiome Medicine, who will be applying the genome editing strategies to help prevent and treat childhood asthma.
鈥淭he Audacious Project incentivizes people to think big. Their donor community understands the power of each of our campuses drawing on our strengths in different ways to have a huge impact around the world,鈥 said Kebreab.
Halting livestock methane emission at its source
Methane emitted in cow burps comes from gas-producing microbes in the gut. Engineering these microbes to produce less methane would help limit emissions before they are burped out.
鈥淲e鈥檙e trying to come up with a solution to reduce methane that is easily accessible and inexpensive, without restrictions or limitations, and that can be made available not only to California but globally,鈥 said Hess.
Hess and Kebreab鈥檚 vision is to one day deliver oral treatments to calves to intervene in their microbial systems at an early stage and reduce methane emissions for the rest of their lifetimes. While this is hypothetical for now, early studies offer hope it could eventually become a global practice.
鈥Engineering microbes directly where they live, without the need to isolate them, has not been done yet because there is no tool to do it. Now, with 新澳门六合彩内幕信息 Berkeley, we will be developing those tools,鈥 said Kebreab.
Hess and Kebreab鈥檚 labs are pairing up their complementary expertise: Hess will test the microbial tools and biocontainment strategies developed at the IGI in a lab setting, then he will deliver findings and results to Kebreab to apply to the animals out in the field.
Solving global challenges with donor support
Cattle are the top agricultural source of methane in the U.S. A third of human-influenced methane emissions are released by cows and other ruminant animals. Because methane doesn鈥檛 stay in the atmosphere as long as other gases like carbon dioxide, reducing emissions now will have a visible impact on the climate within the next decade. California has a mandate to reduce methane emissions 40% by 2030.
鈥淲e are thrilled to be working on this monumental research with collaborators who are on the mission of solving some of the world鈥檚 most pressing problems across climate and health,鈥 said Helene Dillard, dean of the College of Agricultural and Environmental Sciences. 鈥淎nswers to some of the biggest challenges can come from the smallest of things, and we are excited to see how this work with microbes can be part of the solutions.鈥
Kebreab and Hess note how donor support is crucial to such a large, cross-campus collaboration that is needed to solve big global challenges.
鈥淭his type of funding gives us a lot more room to explore things that we might not otherwise be exploring,鈥 said Kebreab. 鈥淭he project gives us freedom to communicate easily with the other faculty members. It really speaks to the power of the 新澳门六合彩内幕信息 system as a whole.鈥
