Researchers find gold nanoparticles capable of 'unzipping' DNA

New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA's double helix. This finding has ramifications for gene therapy research and the ...

RNA-targeting enzyme expands the CRISPR toolkit

Researchers at MIT's McGovern Institute for Brain Research have discovered a bacterial enzyme that they say could expand scientists' CRISPR toolkit, making it easy to cut and edit RNA with the kind of precision that, until ...

Hidden soil fungus, now revealed, is in a class all its own

A type of fungus that's been lurking underground for millions of years, previously known to science only through its DNA, has been cultured, photographed, named and assigned a place on the tree of life.

Mitochondrial DNA reveals unexpected ancestral connections

Biochemists study life on a molecular level. So, as a biochemist, it made sense to investigate my own existence at that deepest of levels, which is why I had my DNA sequenced—my mitochondrial DNA, or mtDNA, to be exact.

Viruses share genes with organisms across the tree of life

A new study finds that viruses share some genes exclusively with cells that are not their hosts. The study, reported in the journal Frontiers in Microbiology, adds to the evidence that viruses swap genes with a variety of ...
