CRISPR Gene-Editing Has Opened Doors for Exotic Model Organisms

Scientists are trying to move beyond conventional model organisms, like fruit flies, zebrafish, yeast, and mice. They started using CRISPR gene-editing technology to craft new model organisms or to study the animals that they are more interested in. The genetic alterations generally take hold but the practical challenges of breeding and maintaining unconventional lab animals […]

Controversial CRISPR “Gene Drives” Tested in Mice

Researchers from the University of California tested gene-drive technology in mice. This controversial application of CRISPR, capable of altering the genomes of entire species, has been applied to mammals for the first time. Although the developed technology has a long way to go before being used for pest control in the wild, it could be […]

CRISPR/Cas Armed with Enzyme That Controls Translation

CRISPR/Cas systems are best known as “gene scissors” for correcting genetic defects. Precise targeting of specific regions in DNA of plants, animals, and microorganisms is the reason CRISPR recently became a favorite tool of many researchers. Now, a group from the University of Freiburg identified an enzyme which assists the CRISPR/Cas system in correctly regulating […]

Single Base Editing Is Now Possible With CRISPR

Researchers have reached a new milestone in CRISPR technology by building an enzyme that can directly transform a DNA base pair from an A-T to a G-C. It will allow for more precise edits than ever before, opening doors for “DNA surgeries” and correction of mutations that cause human diseases.

New CRISPR/Cas9 Therapy Eliminates HIV in Animals

Scientists have managed to completely eliminate the HIV virus in living mice using the revolutionary CRISPR/Cas9 gene-editing technology. They have demonstrated how it excises the viral DNA from the host animal and prevents further infection, providing hope that it could one day benefit humans.
