Researchers publishing in Nature Biotechnology have developed a novel method of editing mitochondrial DNA, which cannot be accomplished with nuclear DNA tools. Where CRISPR doesn't work Why we Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that harm cells and cause...

A preprint published in bioRxiv by scientists working at Rejuvenate Bio has described how gene therapy that allows for OSKM expression can be used to increase the lifespans of mice. A new handle on old problems The researchers begin this study with a discussion of the known problems of aging research. They bring up the...

In a new study published in Journal of Nanobiotechnology, researchers prevented muscle atrophy both in vitro and in vivo by delivering a CRISPR-Cas9 gene editing system packaged in engineered extracellular vesicles [1]. When just using it doesn’t quite cut it Aging is accompanied by the loss of muscle mass, also known as sarcopenia, which deteriorates...

In a new study published in GeroScience, researchers have shown that it is possible to significantly increase yeast lifespan by overexpressing genes highly conserved across various species [1]. Survival and aging The question of the effects of nature versus nurture, or programmed versus stochastic, sparks hot scientific debate in other fields as well as aging....

A new study published in Nature Chemical Biology has described an advancement in the use of retrons, a novel method of genetic engineering that may become superior to CRISPR technology. A new solution for an old problem The researchers begin their paper by pointing out some of the ongoing problems with existing genetic engineering technology....

In a study published in Genome Biology, researchers explain how they are working to make CRISPR less prone to large, accidental deletions of genetic material [1]. A previously unknown large problem While this seems counterintuitive, previous technology only allowed for the ready identification of deletions below 100 base pairs. New technology has allowed for larger...
