Separating the hype from the buzz

David Berube regularly releases on his blog (NanoHype: Nanotechnology Implications and Interactions) interesting short notes about the latest significant nanotech news, what he calls “separating the hype from the buzz”. Follow these owing to the blog RSS feed here or on Nanocolors @ Netvibes here.

Is the nanotech “window of opportunity” closing ?

I recommend you the reading of a recent post by Richard Denison on the Environmental Defense Fund (EDF) “Nanotechnology Notes” blog.

Here is the first paragraph : “As one who has closely followed the emergence of nanotechnology, I am sure I was not alone several years ago in welcoming what appeared to be a refreshingly new attitude among a broad range of stakeholders toward the introduction of this new set of technologies and materials.  Calls from my organization to “get nanotech right the first time” were echoed widely.  Perhaps the most frequently used metaphor, though, was that a “window of opportunity” had opened to do things differently this time.  But I increasingly fear that the window is closing.

World’s first mandatory national nanotech rule soon in Canada ?

According to an article (28/01/2009) on the Project on Emerging Nanotechnologies (PEN) website, the Canadian government is planning to release next February the world’s first national regulation requiring companies to detail their use of engineered nanomaterials ; quantity, usage and toxicity data would be required. According to Andrew Maynard, (chief science advisor for PEN), “This is information that is vital to ensuring the safe use of nanotechnology (…) This decision by Canada (…) is an important step toward ensuring that nanotechnology regulation is driven by accurate information and high-quality science.

Safenano, Project on Emerging Nanotechnologies, 2020 science

Safenano provides information on nanotechnology mostly from the hazards and risks side (newspage, blog,…). One of the main contributors of the Safenano blog is Andrew Maynard, Chief Science Advisor to the Project on Emerging Nanotechnologies ; he recently opened a more generalist science blog entitled “2020 Science“.

International Alliance for NanoEHS Harmonization (IANH)

The launch of the International Alliance for NanoEHS* Harmonization (IANH) was announced at the Nanotox 2008 Conference in Zurich on the 9th of September. According to its website, “the International Alliance for NanoEHS Harmonization is an interdisciplinary alliance of scientific experts, themselves currently active in all aspects of this arena, drawn from Europe, Japan and the United States that seeks to establish reproducible approaches for the study of nanoparticle hazard“. More specifically, the goals are to 1) establish in vitro and in vivo nanomaterial NanoEHS testing protocols that are validated to produce the same results in multiple laboratories internationally and 2) identify nanoEHS in vitro testing protocols that correlate with results in animal test and may be predictive of in vivo effects.
