Ready for a world with low-fat bacon?
Chinese researchers used the gene editing tool CRISPR Cas-9 to create “low fat” pigs.
The study found the pigs produced a leaner meat and were better at surviving colder temperatures.
Researchers believe the genetically modified pigs could reduce economic losses and help boost pig welfare.
A tool like CRISPR opens the door to significant advancements in gene editing. Tools could be used to create not only more resilient animals like pigs, but food like fruits and vegetables.
However, use of tools like CRISPR carry ethical concerns, said Jennifer Doudna, a professor at the University of California—Berkeley.
“CRISPR is a profoundly powerful tool and we must ensure that the public has a strong voice in how it is used,” said Doudna.
