World’s smallest tape recorder is built from microbes

Through a few clever molecular hacks, researchers at Columbia University Medical Center have converted a natural bacterial immune system into a microscopic data recorder, laying the groundwork for a new class of technologies that use bacterial cells for everything from disease diagnosis to environmental monitoring. The researchers modified an ordinary laboratory strain of the ubiquitous … Continue reading “World’s smallest tape recorder is built from microbes”

CRISPR-carrying nanoparticles edit the genome

New delivery system developed by MIT team deletes disease-causing genes and reduces cholesterol. In a new study, MIT researchers have developed nanoparticles that can deliver the CRISPR genome-editing system and specifically modify genes in mice. The team used nanoparticles to carry the CRISPR components, eliminating the need to use viruses for delivery. Using the new … Continue reading “CRISPR-carrying nanoparticles edit the genome”

Scientists Created Low-Fat Pigs by Editing Their Genes With CRISPR

Chinese scientists have created low-fat pigs using new genetic engineering techniques. In a paper published in the Proceedings of the National Academy of Sciences, the scientists report that they have created 12 healthy pigs with about 24 percent less body fat than normal pigs. The scientists created low-fat pigs in the hopes of providing pig … Continue reading “Scientists Created Low-Fat Pigs by Editing Their Genes With CRISPR”

CRISPR stores a Movie into the DNA of Bacteria

For the first time, a primitive movie has been encoded in – and then played back from – DNA in living cells. The research team shows in foundational proof-of-principle experiments that the CRISPR system is able to encode information as complex as a digitized image of a human hand, reminiscent of some of the first … Continue reading “CRISPR stores a Movie into the DNA of Bacteria”
