(Phys.org)—A pair of researchers at MIT has developed what amounts to a "kill switch" for genetically modified organisms (GMOs). In their paper published in the journal Nature Communications, Brian Caliando and Christopher ...
Researchers at the University of York are part of a team of scientist that has discovered how bacteria can restart their 'outboard motor' by hotwiring their own genes.
