Colossal Biosciences said on Wednesday it has succeeded in growing pigeon primordial germ cells, precursor cells to sperm and eggs, for the first time. This is a pivotal step in bringing back the dodo, which was a type of pigeon, for the first time in more than 300 years, according to Colossal. The Texas-based company, which has made splashy headlines for its plans to reestablish wooly mammoths and dire wolves, said it has also developed gene-edited chickens that will act as surrogates for the dodos.

Based on lessons from the New Hampshire men and a handful of other one-off attempts, the Food and Drug Administration approved pig producer eGenesis to begin a rigorous study of kidney xenotransplants. "Right now we have a bottleneck" in finding enough human organs, said Mass General kidney specialist Dr. Leonardo Riella, who will help lead the new clinical trial. More than 100,000 people are on the U.S. transplant list, most who need a kidney, and thousands die waiting.

The Synthetic Human Genome project aims to construct the first synthetic human chromosome, enhancing our understanding of genome biology and medical applications.

In this study, we report the generation of fertile androgenetic mice. Our findings, together with previous achievements of uni-parental reproduction in mammals, support previous speculation that genomic imprinting is the fundamental barrier to the full-term development of uni-parental mammalian embryos.

Considering the wide range of possible applications, it is surprising that there have been no studies to date using CRISPR-Cas9 in spiders.

CRISPR offers more control than viral carriers do, but typically requires the cutting of DNA - raising the chances of unwanted mutations and incomplete repair.

Precision breeding is a real chance to transform how we grow crops here in England. We can turbo charge the natural breeding process our farmers have used for generations to create food that's more nutritious.
