Scientists have created a new weapon to test in the fight against the deadly brain cancer glioblastoma multiforme. By packing strands of small interfering ribonucleic acid, or siRNA, onto the surfaces of gold nanoparticles, they made a nanomedicine that entered the brains of mice and then slipped into tumor cells. There, the siRNA neutralized genes that make those cells flourish.

“Glioblastoma multiforme is one of the worst cancers one can get,” says "; $("#ERA_RC").html(contextualDefault); } }); var era_rc1 = {StyleId: '1',ERADomain: 'cen.firstlightera.com'};
