It’s funny how one thing leads to another. The video of my Friday Evening Discourse at the Royal Institution last year caught the attention of a former colleague and produced an invitation to contribute a lecture to her plans to celebrate the International Year of Crystallography at the University of Western Australia in Perth this summer.

Science has been extraordinarily successful at taking the measure of the world, but paradoxically the world finds it extraordinarily difficult to take the measure of science — or any type of scholarship for that matter. That is not for want of trying, as any researcher who has submitted a PhD thesis for examination or a manuscript for publication or an application for funding will know.

Last night on Twitter someone posted a ‘selfie’ taken by the Mars Curiosity rover. It’s quite a photograph, particularly since it captures a fantastic piece of human technology amidst the landscape of another planet. The detail is what makes the picture. If you click to get a larger view you can see the nuts and bolts holding the rover together and the waves of sand on the Martian surface. My reaction was immediate.

The Society for General Microbiology (SGM) kindly awarded me this year’s Peter Wildy Prize Lecture, which I delivered at their Spring meeting in Liverpool just a few weeks ago. The prize is given for “an outstanding contribution to microbiology education and/or communication in order to stimulate interest and understanding in the subject”. It sounds rather grand, but please don’t be put off.

Last night I lost my virginity. To be precise, I lost my Café Scientifique virginity because I gave a talk about science in a café in Portsmouth at the kind invitation of local organiser Maricar Jagger. It was a really good evening. I gave a short talk about my research and how I see my role as a scientist in modern Britain to a varied and interested audience who proceeded to ask lots of questions.

For researchers who have never dipped a toe into the debates on open access that surge across the blogosphere it is all too easy to imagine that they need not get involved. For sure, people are increasingly aware that a decision of some sort needs to be made about OA once their paper is accepted for publication but that’s about as far as it goes. The complexity of the issue is off-putting — who has the time?

A opinion piece by Anurag Agrawal that was rather skeptical about some aspects of moves toward open access was published in the March issue of Trends in Plant Sciences . I felt several of the arguments advanced by Agrawal were rather weak and was glad to have the opportunity to write a rejoinder which has now been published in the April edition of the same journal.

After splashdown at 4:51 pm on 24th July 1969 the Apollo 11 astronauts returning from the first moon landing  had to don full-body Biological Isolation Garments before they could leave the conical command module that was bobbing in the Pacific Ocean. Having transferred to the dingy that had come to meet them, Neil Armstrong, Buzz Aldrin and Michael Collins then had to scrub one another’s suits with diluted bleach.

I recently came across a film on YouTube called ‘Unedited footage of the bombing of Nagasaki (silent)’. It is one of the dullest and most horrific things I have ever seen. The film shows US servicemen on Tinian island performing the banal tasks needed to prepare the Fat Man bomb before it was dropped on Japan.

I may not know much about art but I know what I like and I like the work of Joseph Mallord William Turner — all the more so now that I have seen the Turner and the Sea exhibition at the National Maritime Museum.

I’ve reached that age where my eye is drawn to the obituary column every time I open the newspaper. It hasn’t been a conscious move but, having arrived at my fiftieth year, I am increasingly aware of the hopes of youth shedding and floating away, like leaves from a tree, and find myself more often looking back over the road now travelled than peering into the future at the way ahead.
