Materials and how we use them are inextricably linked to the development of human society. Yet amazing as historic achievements using stone, wood, metals and other substances seem, these are unbelievably crude compared to the full potential of what could be achieved with designer materials.

On Thursday this week, the Wall Street Journal reported that Ebola victims in Nigeria’s commercial capital Lagos will receive Nano Silver in an attempt to treat the infection. The news comes hot on the heels of the World Health Organization’s decision to sanction the use of unlicensed Ebola drugs in West Africa on ethical grounds. It also coincides with a US Food and Drug Administration statement released yesterday warning against fraudulent Ebola treatment products.
I consider myself to be pretty self-aware. It’s an illusion of course, but one I am usually blissfully ignorant of. Until some insightful reporter shatters it! This was me a few days ago. I was talking with a journalist about science communication and the perils and pitfalls faced by young scientists. As I got into my groove talking about scientists and communication, she interrupted me and asked, “do you think there many scientists that hold such unusual views?” (or words to that effect).
What has the Maker Movement got to do with public health? Quite a lot as it turns out, as I explore in the latest Risk Bites video. This in turn was inspired by being invited to talk at the inaugural We Make Health Fest in Ann Arbor (August 16 – please join us if you can!).
When you’re facing a life or death situation, what do the odds mean – to you personally? As Brian Zikmund-Fisher from the University of Michigan School of Public Health pointed out to Robert Siegel on NPR yesterday, “We’re never 95 percent alive. We either live or die. We experience outcomes”.
Over the past few weeks, revelations of potentially dangerous errors in US federal labs handling pathogens have placed health and safety high on the national agenda. In June, the US Centers for Disease Control and Prevention (CDC) announced as many as 75 of its staff may have been exposed to anthrax due to safety issues at one of its labs. At the beginning of July, vials of smallpox virus were found in an unsecured room at the National Institutes of Health (NIH). Then earlier this week came...
Over the past few days, the interweb’s been awash with virtual “oohs” and “ahs” over Surrey Nanosystems’ carbon nanotube-based Vantablack coating. The material – which absorbs over 99.9% of light falling onto it and is claimed to be the world’s darkest material – is made up of a densely packed “forest” of vertically aligned carbon nanotubes (see the image below). In fact the name “vanta” stands for Vertically Aligned NanoTube Array.
The World Economic Forum’s Global Agenda Council on Emerging Technologies on February 25, 2014 released its annual list of breakthrough technologies. The list highlights 10 trends in technological advancement that could offer innovative solutions to a range of pressing global challenges. As a member of the council that compiles the list each year, I’m excited to see technologies here that could be truly transformative. At the same time, realizing the benefits they offer will require a good dose of responsible inn...
Jim Thomas of the ETC Group has just posted a well reasoned article on the Guardian website on the challenges of defining the the emerging technology of “synthetic biology”. The article is the latest in a series of exchanges addressing the potential risks of the technology and its effective regulation.
Over the past few days, my news and social media streams have been inundated by articles on “nanojuice”. The “juice” – developed by researchers at the University of Buffalo and published in the journal Nature Nanotechnology – is a suspension of light-absorbing nanoparticles which, when drunk (and only mice have had this privilege so far), allow an unprecedented level of real-time imaging of the small intestine. It also presents an unusual series of safety challenges as the particles are de...
