A nasal spray to counter shyness:

The researchers say that the spray harnesses the powers of a feel-good hormone called oxytocin, a neurotransmitter in the brain that is involved in social recognition and bonding.

The mammalian hormone is produced naturally by the body when a person is in love, and it also induces labour in pregnant women. The spray contains a synthetic version of it, created in the laboratory.

University researcher Dr Markus Heinrichs says that the spray was found to "dramatically" change the behaviour of 70 adults during a study. He says that all study participants had stopped feeling anxious, and started to engage better with others in the group.
