2020年7月23日 · Scientists at the University of California, Davis, have successfully produced a bull calf, named Cosmo, who was genome-edited as an embryo so that he’ll produce more male offspring. The research was presented in a poster today (July 23) at the American Society of Animal Science meeting.

2020年7月24日 · Crispr is essentially a programmable molecular scalpel. It works by targeting a particular location in the genome and slicing through the double helix backbone of the DNA.

2019年10月7日 · We crossed one genome-edited dairy bull, homozygous for the dominant PC Celtic POLLED allele, with horned cows (pp) and obtained six heterozygous (PCp) polled calves.

2019年10月22日 · With the rise of CRISPR, scientists can now quickly and cheaply experiment with a myriad of gene-edited crops and other food products. Rather than sticking foreign genes into crops, it’s already possible to mimic naturally-occurring mutations to boost pest-resistant abilities, increase yields, or amp up nutritional values.

2019年3月19日 · About five years ago, their father, a bull, was genetically dehorned by a Minnesota-based company called Recombinetics. Just as egg farmers prefer hens, dairy farmers prefer polled, or hornless,...

2020年7月24日 · Scientists Use CRISPR Technology to Insert Sex-Determining Gene. Scientists at the University of California, Davis, have successfully produced a bull calf, named Cosmo, who was genome-edited as an embryo so that he’ll produce more male offspring. The research was presented in a poster yesterday,

2020年7月29日 · Scientists at the University of California, Davis have successfully produced a bull calf who was genome-edited as an embryo so that he will produce more male offspring. The bull, named Cosmo, was presented in a poster at the American …

2021年2月12日 · We monitored and analyzed the development of the SRY-GFP knock-in bull calf produced by cytoplasmic injection of a homology mediated end joining donor template and the CRISPR-Cas9 system in bovine zygotes.

2020年7月23日 · Scientists Use CRISPR Technology to Insert Sex-Determining Gene. Scientists at the University of California, Davis, have successfully produced a bull calf, named Cosmo, who was genome-edited as an embryo so that he’ll produce more male offspring.

2020年8月13日 · CRISPR is one of a suite of genetic engineering techniques being used to create "new GMOs" — genetically modified organisms that are sometimes marketed (falsely, according to most definitions) as non-GMO just because they don't include foreign genetic material in the final product.
