Life Beyond Earth
There has been, until now, no compelling evidence for biology beyond the confines of our own planet. And yet, people who investigate this topic feel confident that – within two decades – we will trip across life forms that are not, and never have been, earthlings. Why are they so optimistic that we will soon find some cosmic confrères, and what might be the implications of such a discovery?

The 10th International Workshop on Nanoscale Spectroscopy and Nanotechnology – NSS10

10—13 September 2018, Oxford, UK
NSS10 bringing together experts to discuss and share the information on latest research advances of science and technology in the nanoscale regime including (but not limited to) electronic, optical, magnetic, mechanical and transport properties of nanoscale systems and nanoscale devices, as well as characterisation tools to study them. It will additionally focus on low dimensional materials, catalysis, energy materials, topological materials and their practical applications.
