A recipe for making strings in the lab

Theoretical physicists in the Netherlands have proposed a way to make
superstrings in the laboratory. If their ideas can be put into
practice, it would allow aspects of string theory to be explored in an
experiment for the first time. The new ideas rely on exploiting the
properties of ultracold atomic gases

String theorists attempt to explain all the fundamental particles as
vibrations on tiny strings on length scales of about 10-33 metres. The
theory naturally includes "supersymmetry" - a symmetry that connects
particles with integer spin, known as bosons, to particles with
half-integer spin, which are known as fermions. The particles that
carry the fundamental forces of nature, such as the photon and the
gluon, are bosons, while the quarks and leptons that make up matter are
fermions. Although superstring theory is the leading candidate for a
theory of everything, there is no experimental evidence to date for
strings or supersymmetry.
