New technique enables safer gene-editing therapy using CRISPR

Scientists from The University of Texas at Austin took an important step toward safer gene-editing cures for life-threatening disorders, from cancer to HIV to Huntington's disease, by developing a technique that can spot ...

What's a knot—and what's not—in genomic mapping

While DNA sequencing provides precise, nucleotide-by-nucleotide genomic information, genome mapping provides a bigger-picture perspective of sequenced DNA that can provide valuable structural information. Like mapping roads ...

Researchers discover unique DNA editing function

A species of unicellular ciliate has found a special trick to make use of the cellular machinery in seemingly impossible ways. Researchers at the University of Bern have for the first time described a mechanism in detail ...

Genetic key to salt-tolerance discovered in tilapia fish

Most fish live either in fresh water or salt water, but others, including tilapia, have the remarkable ability to physiologically adjust to varying salinity levels—a trait that may be critically important as climate change ...

DNA structure influences the function of transcription factors

Substances known as transcription factors often determine how a cell develops as well as which proteins it produces and in what quantities. Transcription factors bind to a section of DNA and control how strongly a gene in ...
