The world’s smallest lasso has been created by scientists in Saudi Arabia and the US. The molecular device threads through itself, forming a reversible noose, in response to chemical and electronic stimuli.

The research team, led by 2016 Nobel prize-winner Fraser Stoddart of Northwestern University, were inspired by naturally occurring lasso peptides – molecules produced by a variety of bacteria, which consist of a linear peptide tail laced through a macrolactam ring.
