A new gene-editing technique enables the correction of multiple genetic mutations simultaneously, transforming the prospects for millions living with complex inherited diseases, such as cystic ...

As people grow older, their immune systems do not simply slow down, they often become locked into a simmering, ...

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...

While CRISPR is probably the most prominent gene-editing technology, there are others, some developed before and since. And people have been developing CRISPR variants to perform more specialized ...

For many species, producing an embryo is a bit of a contest between males and females. Males want as many offspring as possible and want the females to devote as many resources as possible to each of ...

A powerful form of DNA-editing machinery discovered in bacteria might allow us to make much bigger changes to genomes than is currently possible with CRISPR-based techniques. However, it isn’t yet ...

Genome editing is a powerful biotechnology tool that allows scientists to make precise changes to an organism's DNA. It involves the use of specialized enzymes, known as engineered nucleases or ...

Gene editing inside living cells could become more effective and accurate after researchers unveiled how inner workings can help or hinder the process. Professor Rick Russell (left) and graduate ...
