Houston Methodist scientists have uncovered an unexpected side of a protein best known for its link to brain diseases. The ...

All complex biological systems—like the DNA, RNA and proteins constantly being copied and built within our cells—are prone to errors. That means as life evolved to be more elaborate, it also had to ...

A common type of error-correcting mechanism in biology is called kinetic proofreading. For example, if errors turn up when cells are making new DNA, enzymes can cut out incorrect nucleotides. They can ...

In a French criminal trial, conventional DNA analysis couldn’t distinguish between twin brothers, but emerging scientific ...

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million ...

Genome editing-based therapies typically aim to treat disease by correcting underlying genetic mutations in patient's cells.

Researchers uncovered millions of ancient plant DNA switches—some older than flowering plants themselves—revealing a hidden evolutionary blueprint stretching back 400 million years. Most people have ...

DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

Most people alive today carry fragments of Neanderthal DNA in their genome. Now scientists are gaining a more intimate understanding of the ancient encounters that put it there. By Carl Zimmer One of ...

TUCSON, Ariz. — As the Nancy Guthrie case enters week three, investigators and the public are awaiting potentially pivotal DNA results tied to a glove recovered near the scene. But according to ...

A DNA test could help match patients with psychiatric medications, potentially reducing the long and frustrating trial-and-error process.

Genome editing-based therapies typically aim to treat disease by correcting underlying genetic mutations in patient’s cells. However, most genetic disorders are caused by dozens or even thousands of ...
