Confessions of a Scientist Communicator

August 5, 2014

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 ...

How far should universities go in hyping research?

August 1, 2014

An article passed through my Twitter stream today from Gizmodo shouting out “Change Your Hair Color By Etching Nano-Patterns Into Each Strand”. It pretty much mirrors a press release from the University of New Mexico claiming “New technology allows hair to reflect almost any color”. Carbon-copy reporting is pretty much standard these days in science ...

The antibiotics challenge

July 23, 2014

Neil Hawkins at Dow Chemical tweeted me a link to this piece in the New York Times this morning: A Dearth in Innovation for Key Drugs (Eduardo Porter) There is clearly something wrong with pharmaceutical innovation. Antibiotic-resistant infections sicken more than two million Americans every year and kill at least 23,000. The ...

When risk gets personal

July 22, 2014

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”.  Brian’s ...

The gathering storm of lab safety

July 20, 2014

Pathogen safety in federal labs 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 ...

Who’s afraid of carbon nanotubes?

July 18, 2014

I’ve been fascinated by the coverage of Surrey nanosystems’ carbon nanotube-based Vantablack material this week. The material’s had widespread coverage – just Google “vantablack” to see what I mean.  But in amongst all the geeked-out media excitement over the world’s darkest material, there’s been nary a word on the possible health risks ...

New York Times does nanoparticles in sunscreens

July 17, 2014

What are the risks of nanoparticles in sunscreens?

How safe is the world’s darkest material?

July 16, 2014

Vantablack – the new black? 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 ...

Nanotubes create the blackest black – Douglas Adams would be proud

July 14, 2014

If your nanotechnology stream is anything like mine today, it will have been swamped by accounts like this one of “Vantablack” fabric – supposedly the world-s blackest-ever material! The material relies on a carbon nanotube forest that absorbs 99.965% of visible light that lands on it.  Putting aside the questions of safety, ...

Nanoparticle donut math – crunching the numbers

July 14, 2014

Having written yesterday about nanoparticle titanium dioxide (TiO2) concentrations in donuts, Raphaël Lévy asked for some clarification on where I got my figures from.  I thought it easiest to post the analysis in full – it goes a little deep into particle analysis, but on the other hand it’s also a ...

Nanoparticles in Dunkin’ Donuts? Do the math!

July 12, 2014

Nanoparticles in food products Over the past couple of years a number of articles have been posted claiming that we’re eating more food products containing nanoparticles than we know (remember this piece from a couple of weeks ago?).  One of the latest appeared on The Guardian website yesterday with the headline “Activists take aim at ...
