Bomb-sniffing flowers

Scientists in Denmark, the US and Canada have all been working on producing a genetically-engineered plant whose flowers will come up red instead of white in the presence of underground explosives. The idea, of course, is that you can use them to to test for the presence of landmines by dropping the seeds from the air and seeing what colour the flowers are when they come up.

Apart from the benefits if the technology works (and the rampant symbolism), this is the kind of project that the genetic engineers needed to come up with at the start of the technology to help sell it to the public. It would take a very hard person, however suspicious they were of science, to oppose a cheap new mine-detection technology.

Instead, of course, despite all the publicity about how GM products were going to end third-world hunger, reinvigorate medicine and who knows what else, the first major products were herbicide-resistent crops, allowing farmers to use even more toxic chemicals in the quest for ever-more intensive crop production. Personally I think that most of the opposition to GM food is incoherent, illogical and based entirely on prejudice, but I still can’t feel very positive about Round-up Ready soybeans.

The ternness of terns

George Szirtes discusses people’s need to identify things – flowers, birds – something he doesn’t share. Indeed he sets up (but slightly backs away from), an opposition between the botanist’s way of looking and the artists’s way. He ends like this:

Yet all the time I am aware that even an urban citoyen of the imagination should be able to tell a kingfisher by its silhouette as it flashes across a narrow stream or be able to name at least a hundred stars. One should be able to do that really, as well as trying to render the flashing sensation in language and learning to define the starness of stars.

I can’t help feeling that those people – the vast majority – who can’t distinguish a gull from a tern, a swallow from a swift, or a bee from a wasp or a hoverfly, are completely failing to appreciate the ternness of terns.

Being able to recognise something and distinguish it from superficially similar things seems absolutely central to any attempt to learn something about its thingness. The ability to attach a name is secondary to the process of coming to know a thing the way you know a familiar place or a friend.

Conversely, any birdwatcher could tell you that gaining some sense of a bird’s thingness, its inscape, is a key part of learning to identify it. Of course, being a prosaic bunch, they don’t call it ‘inscape’, they call it ‘jizz’. But if there’s a distinction between saying ‘I knew it was a tern because of its tern-like jizz’ and ‘I knew it was a tern because it had ternness’, it would take a better philosopher than me to elucidate it.

Macro

I love the fact my camera has a macro mode. There’s something very satisfying about getting really close to things and taking pics of them.

The sand dunes are just covered in flowers – vetchy type things in scarlet, spikes of ghostly broomrape, mesembryanthemums, pink thistles, big daisies, all sorts of things in all shapes and colours.

a pensée

Although my own main interest is birds, I think if I was advising someone on a natural-history related hobby to take up, I might suggest flowers or insects. I think it’s a great virtue to look closely at the little things. You miss the real action if you tromp through the hills, admiring the view but not noticing the wild flowers at your feet.

You don’t have to pick just one interest, of course. I did much of my early birding with one of my teachers who was also keen on flowers and had a moth trap. He was the one who showed me that, if you look the wrong way through binoculars and bring them very close to something, they act as a powerful magnifying glass.
