TL;DR: Exposing the mesothelial lining of the body cavity of mice to long multiwalled carbon nanotubes results in asbestos-like, length-dependent, pathogenic behaviour, including inflammation and the formation of lesions known as granulomas.

TL;DR: It is suggested that ultra-fine particles in the nature of the urban particulate cloud are able to provoke alveolar inflammation, with release of mediators capable, in susceptible individuals, of causing exacerbations of lung disease and of increasing blood coagulability, thus also explaining the observed increases in cardiovascular deaths associated with urban pollution episodes.

TL;DR: The working group report presents a broad data gathering strategy applicable to this early stage in the development of a risk assessment process for nanomaterials, and there is a strong likelihood that biological activity of nanoparticles will depend on physicochemical parameters not routinely considered in toxicity screening studies.

TL;DR: The pursuit of responsible nanotechnologies can be tackled through a series of grand challenges, argue Andrew D. Maynard and his co-authors, and if they and their colleagues can rise to these challenges the true extent of any risks involved should become clear.

TL;DR: This review shows that only few specific nanoparticles have been investigated in a limited number of test systems and extrapolation of this data to other materials is not possible, and limited ecotoxicological data for nanomaterials precludes a systematic assessment of the impact of Nanoparticles on ecosystems.
