In this focus issue we explore several aspects of education in nanoscience and nanotechnology. The topics are far from being exhaustive; they are an invitation to reflect on the subject and its different facets.   Editorial Top A lot to learn   p783 doi:10.1038/nnano.2013.250 The changing face of nanoscience education around the world. Commentaries Top A guide to mentoring undergraduates in the lab   pp784 - 786 Philip S. Lukeman doi:10.1038/nnano.2013.237 Mentoring undergraduates in a research laboratory requires a different set of skills and approaches than for other lab members. However, if a mentor — be it a faculty member, postdoc or graduate student — can adopt these methods, it can lead to a significantly improved lab experience for everyone involved. Learning and research in the cloud   pp786 - 789 Krishna Madhavan, Michael Zentner & Gerhard Klimeck doi:10.1038/nnano.2013.231 Research and teaching in nanoscience can, and should, be thought as one joint endeavour. nanoHUB, a cyberinfrastructure that aims to use interactive cloud-based software to meet the needs of both code developers and end-users, is redefining research and education in nanoscience and engineering. An education in progress   pp789 - 791 Tebello Nyokong & Janice Limson doi:10.1038/nnano.2013.235 In recent years, South Africa has, like other countries, increased investment in nanotechnology research, which in turn has had an effect on the curricula of its higher-education institutions. However, the focus of these changes, and the approach taken to achieve them, are unique to the circumstances of the country. The road ahead   pp792 - 793 Roberto Cingolani doi:10.1038/nnano.2013.238 In recent years, education in nanotechnology has evolved to reflect the new skill set required to perform multidisciplinary research. As the field further develops, it will need to evolve again.
