Researchers have shown that a site specific double strand break (DSB) generated both in the genome and the donor plasmid using the CRISPR-Cas9 system can be efficiently used to target ∼5 kb plasmids into mammalian genomes via nonhomologous end… Read More
Scientists “resurrected” a mammoth gene by transplanting it into a human kidney cell in the lab. The gene, called TRPV3, is known to affect temperature sensation and hair growth regulation. When they added the mammoth TRPV3 gene to… Read More
A great simplified overview of the complexities involved in genome comparison.
The fossilized blood cells were found in the claw of an a unidentified theropod (a dinosaur group which includes T. rex and velociraptor). The collagen was found in several other bones, including ribs from unknown species or genuses…. Read More
The question “how far should we go to bring back a lost species?” opens a deeper discussion that requires us to consider what kind of world we want now and for the future. In answering, I am considering… Read More
