A nightshirt containing elastic fibres coated in carbon nanotubes could detect the long pauses in breathing characteristic of sleep apnoea. A small current flows through the nanotubes, which change their conductance as the fibres stretch with breathing. Any disturbance is signalled by current changes. The wireless-enabled shirt, made by Jose Abraham of the University of Arkansas, allows wearers to sleep in a natural position. Electrical interference from household appliances can slow down broadband. Now British Telecom is testing a device in homes called the iPlate, which filters out interference. In a recent demonstration,
