At the frontiers of the science of health risk – five areas to watch

by Andrew Maynard January 2, 2013

Cross-posted from Risk Sense This week’s Risk Bites video takes a roller-coaster ride through some of the hottest topics in risk science. Admittedly this is a somewhat personal list, and rather constrained by being compressed into a two and a half minute video for a broad audience. But it does touch on some of the […]

A bluffer’s guide to Risk Science in the 21st century

by Andrew Maynard January 4, 2011

A few weeks ago, I gave a talk at the Contemporary Arts Center in Cincinnati under the slightly provocative title “Small Gods and the Art of Technology Innovation”.  The talk is now available on-line (slides and audio at least) – and viewable below – through the excellent work of the folk at CAC. Rather sneakily, […]

Could precisely engineered nanoparticles provide a novel geoengineering tool?

by Andrew Maynard September 13, 2010

This is an extremely quick and dirty blog post, as I really need to be somewhere else.  But while traveling to the World Economic Forum meeting in China today, I came across a new paper that piques my interest. The paper is by David Keith at the University of Calgary (published in the Proceedings of […]

Ten emerging technology trends to watch over the next decade

by Andrew Maynard December 25, 2009

Ten years ago at the close of the 20th century, people the world over were obsessing about the millennium bug – an unanticipated glitch arising from an earlier technology.  I wonder how clear it was then that, despite this storm in what turned out to be a rather small teacup, the following decade would see […]

Reversing the Technological Dilemma

by Guest December 17, 2009

By George Kimbrell, International Center for Technology Assessment, and the Center for Food Safety A guest blog in the Alternative Perspectives on Technology Innovation series Andrew asked us to write about “how technological innovation should contribute to life in the 21st century.”  Technological innovation is often blindly referred to as “progress.”  The question is — […]

Geoengineering options: Balancing effectiveness and safety

by Andrew Maynard September 1, 2009

An interesting aspect of today’s Royal Society report on geoengineering is the attempt to rate twelve potential approaches to engineering the climate by effectiveness, affordability, timeliness and safety – and to graphically compare the approaches in terms of these criteria. While the ratings and the resulting diagram are somewhat subjective (the report’s authors call them […]

Engaging the public on nanotechnology

by Andrew Maynard July 7, 2009

Following up on my last post – Geoengineering the planet with nanotechnology ice-cream? – here’s a short video Zoe Papadopoulou and colleagues put together on The Cloud Project from my visit in June: Get the Flash Player to see this content. Although this was filmed before the finishing touches had been applied to the ice […]

Geoengineering the planet with nanotechnology ice-cream?

by Andrew Maynard July 5, 2009

Scientists and engineers have their moments. But it they are hard pressed to beat art students when it comes to sheer audacious creativity. Earlier this year I received an email so intriguing I couldn’t help but follow up on it. The email was from Zoe Papadopoulou, an MA student at the Royal College of Art […]

Geoengineering: Are we grown up enough to handle it?

by Andrew Maynard June 14, 2009

If there’s one thing that’s guaranteed to unite global warming “denialists” on both sides of the aisle, it’s geoengineering – the intentional planet-wide manipulation of the environment.  At least, you might be left with that impression after reading the comments following a thoughtful piece in Monday’s Wall Street Journal by Jamais Cascio. Cascio describes himself […]

Steve Chu’s White Revolution

by Andrew Maynard May 27, 2009

It feels good to be ahead of the curve sometimes. About this time last year, I was slaving away painting my roof white – much to the bemusement of my Northern Virginia neighbors and friends. So I couldn’t help feeling just a little smug this morning as I read that US Secretary of Energy Steve […]

Geoengineering goes mainstream

by Andrew Maynard April 8, 2009

Twelve months ago, geoengineering seemed little more than the fancy of science fiction writers and fringe scientists.  Now, an increasing number of people are viewing it as a viable – if extreme – option for curbing global warming.  This shift was hammered home today by Dr. John Holdren, President Obama’s science advisor, in his first […]

Geoengineering: Does it need a dose of geoethics?

by Andrew Maynard January 28, 2009

It’s been a big week for geoengineering.  First there was the news that the world’s largest geoengineering experiment to date is about to start in the Southern Ocean.  Following close behind was a new study on how geoengineering projects could potentially impact global climate change, ranging from covering vast tracts of desert with a reflective […]
