If you want proof that nano is mainstream, just pick up the U.S. May edition of fashion magazine “Elle.” Sharing cover-space with Madonna is the latest article on nanotech and the beauty business.
Elle might not be your first choice of reading for cutting edge science, but Joanne Chen’s article “Small Wonders” is no slouch when it comes to conveying complex ideas in digestible bites. Using beauty products as examples (from hair dryers to conditioners to anti-wrinkle cream), Chen takes the reader on a journey through the wonders and worries of nano. As an exercise in making nanotechnology accessible, the article is a must-read. Read the rest of this entry »

The most recent estimate from the U.S. National Nanotechnology Initiative (NNI) puts nanotechnology risk research investment at $68 million for 2006 (the only year complete figures are currently available for—apparently). Yet theProject on Emerging Nanotechnologies (PEN) has just completed its own assessment—and could only find $13 million associated with research projects primarily focused on addressing nanotechnology risk in the same year. What gives—are the feds indulging in a bit of creative accounting; or have PEN forgotten the basic rules of arithmetic?
Let’s be honest, I’m not a great fan of bean-counting. Evaluating research in terms of dollars invested (or Pounds or Euros) is a crude tool at the best of times. But when it comes to assessing investments and returns, the fact is that bottom-line figures count. Read the rest of this entry »

Here’s a small diversion for a slow Sunday afternoon: Take sixty jellybeans and ninety cocktail sticks, and try to construct a model of a buckyball—a carbon-60 molecule. It’s tricky, but not impossible.
Constructing a candy buckminster fullerene is one of ten nano “experiments” in a new nanotechnology education kit from nanobits. Designed to enthuse and inform kids in school and at home about nanotechnology, the nanobits kit grew out of Nanovic (Nanotechnology Victoria Ltd.)—an Australian initiative to translate nanotechnology research into commercial applications.

The small American town of Sunnyville is a town in crisis. Against a backdrop of job losses that have decimated the local community, citizens are struggling to decide whether to welcome two major nanotech-enabled industries into the town, or whether to reject them because the new technology might create more problems than it solves.
As if this wasn’t enough, it has just come to light that local company “Happy Home Paint” has been contaminating a neighborhood beauty spot with toxic chemicals for years, and the only way of cleaning the area without destroying it is by using a developmental nanoparticle-based technology.
Will nanotechnology revitalize this town, or will it end up being the straw that breaks the camel’s back? The locals are having a tough time deciding. Read the rest of this entry »

On March 18th, the science fiction writer Arthur C. Clarke died in his home in Sri Lanka at the age of 90. A master developer and assembler of ideas, Clarke will be remembered fondly by many for igniting their enthusiasm for science, and how it might be used to better our lives. His passing leaves a hole in the ranks of science heroes who inspire us to look beyond the obvious, and question the unquestionable.
My early childhood was full of the stories of Clarke, Asimov and others, and without a doubt these writers set me on a path to exploring how the world works and how we can extend our reach with this knowledge. Clarke had the knack of taking what was known, and pushing it that little bit further into the realms of the “what if…?”. In doing so, he was the perfect foil to the established scientific community; asking the questions others shied away from and stimulating the process of discovery and development afresh. But he also excelled at raising scientific consciousness across the board, and sowing the seeds of effective and informed science engagement. Read the rest of this entry »

Can current approaches to doing science sustain us over the next one hundred years? An increasing reliance on technological fixes to global challenges — including nanotechnology — demands a radical rethink of how we use science in the service of society.
Over the next century we will perhaps be facing the greatest challenge in the history of humanity: sustaining six billion plus people on a planet where natural resources are running scarce and our every action results in a palpable environmental reaction. Progress towards sustainability will only come through integrating relevant science with socially-responsible decision making. Yet the science policy dogmas of the 20th century may be stretched to breaking point in the face of 21st century challenges. Read the rest of this entry »

What determines your view of nanotechnology—the message, or the messenger? Most of us would like to think it is the message that governs our internal risk-benefit analysis. But research published this week suggests other factors may be at work.
Dan Kahan at Yale Law School and his colleagues are shaking up our ideas on effective communication and engagement when it comes to complex issues like emerging nanotechnologies. They have already demonstrated what many jaded science communicators have learned the hard way—that shouting louder and longer about the facts doesn’t necessarily lead to “right-minded” thinking in the general population.* In their latest study (available here) they show that when it comes to balancing possible nanotechnology benefits and risks, the messenger is quite possibly as important as the message.

Labeling – is there anything more contentious in the safe nanotech debate? Some are fearful that too much knowledge will confuse and worry muddle-headed consumers. Others can only see the marketing opportunities of a “nano-inside” label. Then you have the nano-doomsday merchants, who seemingly would like nothing better than to slap a bright yellow nano-hazard sticker on all things small.
And of course, we cannot forget those “magic” nano products – not the surface treatment that allegedly messed people’s lungs up (which was neither magic, nor nano) – but those items which miraculously change from “nano-enabled” to “nano-no-more” at the wave of a marketing executive’s wand.

The popular computer game “SimLife” allows users to create and manipulate virtual people. But what are the chances of us one day being able to do the same with real organisms: building new life-forms out of basic chemicals, so “SimLife” becomes “SynLife”?
This week’s announcement by J. Craig Venter’s team (and the associated paper in Science) that they have successfully synthesized the complete genome of the bacterium Mycoplasma genitalium is an important step towards achieving what is becoming known as “synthetic biology”. By constructing complete DNA sequences from scratch, the door is being opened to transforming common laboratory chemicals into new living organisms; that are engineered with specific purposes in mind. And perhaps not surprisingly, this manipulation of DNA at the nanoscale is increasingly being seen as part of the “nanotechnology revolution”.
But is synthetic biology really nanotechnology? Read the rest of this entry »

With apologies to Arundhati Roi for “borrowing” the title of her moving book, what—if anything—has nanotechnology got to do with religion?
Barnaby Feder of the New York Times takes on this issue in his latest posting to the Bits blog:
“There may not be a lot of agreement among the world’s religions on exactly what constitutes humans “playing God,” but you never hear a preacher or rabbi suggesting such behavior is wise or laudable. So you would think they might have a lot to say about nanotechnology. After all, nanotech involves rearranging not just DNA and the other building blocks of life — already a source of controversy in biotechnology — but the very atoms and molecules that make up all matter. If that is not messing around in God’s closet, what is?”
The big issue it seems is transhumanism—the use of existing and emerging technologies, including nanotechnology, to extend and change what it means to be human. Will nanotechnology give us the ability to do what only God should? Can we somehow thwart God’s plans, and take control of our own destiny? Or is there nano-knowledge that should be forbidden?

What do Alzheimers and body armour have in common? The answer could lie in the structures formed when proteins self-assemble at the nanoscale.
At the end of last year, The Daily Telegraph Science Editor Roger Highfield wrote in an article:
“The protein linked with Alzheimer’s disease has inspired the design of “nanoyarns” that could be put to a vast range of uses, from body armour to parachutes and super strong nets.”
The research, published in the journal Science by Tuomas Knowles and other members of Mark Welland’s team at the University of Cambridge (U.K.), studied the properties of nanometre-diameter fibrils formed from misfolding proteins. In tests, these fibrils showed the potential to outperform many conventional natural materials, leading to Knowles and colleagues referring to them as “a class of high performance biomaterials”.

In 2004, the US National Nanotechnology Initiative (NNI) had a strategy – and it was OK. But what has happened since then? Has progress been made against planned actions? What have been the major challenges to progress? Have effective solutions been found? And how have the lessons and experiences of the last three years influenced strategic nano-thinking in the government?
You might be forgiven for supposing that the updated Strategic Plan – published this week – holds the answers. No such luck! Read the rest of this entry »

Are we so caught up in the thrill of nanotechnology, that we are blind to future pitfalls? Are we having the new technology ride of our lives—with someone else’s future? Are we living for the nanotech moment, and leaving the consequences to others to deal with? In short, are we on a nanotechnology joyride? Read the rest of this entry »

If you’ve ever wondered how to deal with the complexities of regulating a twenty first century technology like nanotechnology, wonder no more. Last week, President Bush’s top advisors on science and the environment published a set of “principles for nanotechnology environment, health and safety oversight”. Read the rest of this entry »

Some nanotechnology events should come with a health warning, perhaps along the lines of: “This meeting could seriously alter your perspective”. Because nanotechnology crosses such diverse areas of interest and expertise, there is a danger of being exposed to ideas that are radically different from your own. And where exposure occurs, “infection” becomes an issue. Read the rest of this entry »

In July 2007, a specially convened task force of the United States Food and Drug Administration (FDA) concluded that size does in fact matter (FDA 2007). The focus of the task force was not on the importance of “largeness”, but rather on the technology of the unimaginably small—nanotechnology.
Nanotechnology is the technology of manipulating matter at near-atomic levels; typically, but not exclusively, within the size range of 1 – 100 nanometers. Working at this scale, it becomes possible to combine materials in ways and forms unimaginable more than a few decades ago. Imagine the contrast between eighteenth century surgery and modern microsurgery, and you begin to get an idea of what this emerging technology offers.
According to the FDA task force, “properties of a material relevant to the safety and (as applicable) effectiveness of FDA-regulated products might change repeatedly as size enters into or varies within the nanoscale range”. But as Professor James Moor and Professor John Wecker point out in the Spring 2007 edition of Medical Ethics [PDF, 805 KB], nanotechnology not only raises safety and regulatory issues, but ethical questions as well (Moor and Wecker 2007).

Somewhere, I must have taken a wrong turn in my life. Three years ago, I was a serious scientist, doing research no-one understood, and writing papers no-one read. Now I find myself making videos about cream cakes.
It all started to go amiss when I got mixed up with a crowd with crazy ideas about engaging people on science. First it was the small stuff—being interviewed by ten-year-olds about nanotechnology. Before I knew it I was writing letters to fictional characters about nanotechnology policy (I’m still waiting for an answer from Arthur Weasley by the way…). But this week I hit rock bottom: a video extolling the educational potential of an American artificial cream-stuffed sponge cake—the Twinkie! Read the rest of this entry »

Admit it-deep down, your don’t really believe people will be exposed to engineered nanomaterials. After all, most nanomaterials will be made in enclosed reactors, handled as precious commodities where not a particle can be spared, and irreversibly incorporated into a bewildering array of products. And those that do start their life as nanoparticles will clump together in the blink of an eye, becoming nano-no-more before anyone can breathe them, touch them or (goodness forbid) eat them!
At least, that is how the argument goes. Read the rest of this entry »
