Think Design – an alternative take on nanotech (in 11 minutes!)

A few weeks ago I was asked to give a “TED style talk” on nanotechnology for the University of Michigan Environmental Health Sciences department 125th anniversary.  What they got was a short talk on “thinking small”: The other talks in the series are also worth checking out – covering topics as diverse as epigenetics, cancer, ...

Carbon nanoparticles could be ubiquitous to many foods

TEM images of carbon particles from foods containing caramelized sugar. Click to see larger image. Source: Palashudding et al. Nanotechnology leads to novel materials, new exposures and potentially unique health and environmental risks – or so the argument goes.  But an increasing body of research is showing that relatively uniformly sized nanometer scale particles are ...

Nanoparticles, cosmetics and sunscreens – again!

Robin Erb has a good piece on cosmetics and safe ingredients in the Detroit Free Press this week – it tackles the very limited regulation over what goes into cosmetics, but balances this with a useful perspective on consumer choice and how this in turn can drive business decisions on what is used and how.  ...

Nano M&Ms?

Not in the technical sense I’m afraid, but thought it would be fun to post this image of nano-branded M&Ms.  They were used as part of a recent NanoDays session with local school kids exploring the broader implications of nanotechnology. The only substantive link they have with real nano-enabled products as far as I can ...

Nano quadrotors – a game-changing technology innovation, but can we handle it?

It’s been hard to avoid the buzz surrounding nano quadrotors this week, following the posting of Vijay Kumar’s jaw-dropping TED talk – and the associated viral video of the semi-autonomous machines playing the James Bond theme. The quadrotors are impressive – incredibly impressive.  But I’m sure I am not the only person watching these videos ...

Is Maynard going over to the nano-dark side?

A few weeks ago I spent some time chatting with Howard Lovy for an article for the Nanobusiness Commercialization Association.  That interview was posted by Vincent Caprio on his blog a few days ago, and raised a few eyebrows – was I showing signs of becoming a nano-risk skeptic? I hope not, as as I ...

Are consumers risking skin cancer because of fears over nanoparticles in sunscreens?

This has just landed in my email in box from Craig Cormick at the Department of Industry, Innovation, Science, Research and Tertiary Education in Australia, and I thought I would pass it on given the string of posts on nanoparticles in sunscreens on 2020 Science over the past few years: At Australia’s International Conference on ...

Wonders and Worries – Retro nano at its best!

Here’s an introduction to the “wonders and worries of nanotechnology” that I think is rather brilliant: It’s part of a series being produced by the Science Museum of Minnesota for the Nanoscale Informal Science Education network (NISE Net). The series is designed to stimulate discussions addressing the societal and ethical implication of nanotechnology – but ...

World Economic Forum: Top Emerging Technologies Trends

For the past few months, the World Economic Forum Global Agenda Council on Emerging Technologies has been working on identifying some of the most significant trends in technology innovation.  Published yesterday by WEF, these represent ten areas that we as a council felt are likely to shake things up over the next few years in ...

National Academy publishes new nanomaterials risk research strategy

The US National Academy of Science today published its long-awaited Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials. I won’t comment extensively on the report as I was a member of the committee that wrote it.  But I did want to highlight a number of aspects of it that I think are ...
