Hubert Duprat



Duprat's aquatic caddis fly larvae, with cases incorporating gold, opal, and turquoise, among other materials.

The images above illustrate the results of an unusual artistic collaboration between the French artist Hubert Duprat and a group of caddis fly larvae. A small winged insect belonging to the order Trichoptera and closely related to the butterfly, caddis flies live near streams and ponds and produce aquatic larvae that protect their developing bodies by manufacturing shea ths, or cases, spun from silk and incorporating substances—grains of sand, particles of mineral or plant material, bits of fish bone or crustacean shell—readily available in their benthic ecosystem. The larvae are remarkably adaptable: if other suitable materials are introduced into their environment, they will often incorporate those as well.

Duprat, who was born in 1957, began working with caddis fly larvae in the early 1980s. An avid naturalist since childhood, he was aware of the caddis fly in its role as a favored bait for trout fishermen, but his idea for the project depicted here began, he has said, after observing prospectors panning for gold in the Ariège river in southwestern France. After collecting the larvae from their normal environments, he relocates them to his studio where he gently removes their own natural cases and then places them in aquaria that he fills with alternative materials from which they can begin to recreate their protective sheaths. He began with only gold spangles but has since also added the kinds of semi-precious and precious stones (including turquoise, opals, lapis lazuli and coral, as well as pearls, rubies, sapphires, and diamonds) seen here. The insects do not always incorporate all the available materials into their case designs, and certain larvae, Duprat notes, seem to have better facility with some materials than with others. Additionally, cases built by one insect and then discarded when it evolves into its fly state are sometimes recovered by other larvae, who may repurpose it by adding to or altering its size and form.

Duprat traces his work with the caddis fly larvae back to pioneering nineteenth-century entomologists such as François-Jules Pictet and Jean-Henri Fabre, who both conducted experiments in which structure-building insects were given alternative, non-indigenous materials. Seen within the context of the artist's work—a practice that has often addressed aspects of mimesis in the realms of both nature and facture through his conceptual sculptural activities—the caddis fly larvae project is an example of Duprat's ongoing interest in productive collisions between organic forms and technologized materials. Yet the work also provokes broader philosophical questions regarding behavior and intent, one that was summarized particularly astutely by the critic and philosopher Christian Besson, in a conversation with the artist conducted in the late 1990s:

Kant's distinction between works of art and those of nature leaves us in a quandary. The production of the artifact within nature herself poses a problem—even more so when an aesthetic aspect is involved. Whether the insect is a craftsperson or whether, more generally, nature is a creator of forms, the consideration, within nature, of an aesthetic dimension is the stumbling block of science. ...

Your activity as an artist, upsetting the ordinary ethology of the insect, seems to me to be the same thing as introducing a
noise, complicating itsumwelt and producing a response. In your diversion of the caddis worm's behavior, in your artistic manipulation, the effect is twofold. From a biological viewpoint, a random event triggers self-organization. From a human viewpoint, the experimenter's intent produces this effect. ...

Is the caddis worm's precious case the work of the insect or the work of the artist? This is not the right question. The contradiction can be resolved by the differing viewpoints. According to the first view, the caddis worm owed nothing to the artist (who is simply the author of one noise among the thousands of other noises in its environment). According to the second view, the caddis worm is merely the executor of the artist's project. The artistic statement plays on the confusion of the two levels by overlaying the two perspectives. The aesthetic result (at once natural and artistic) turns the caddis worm's case—which is more than an assisted ready-made or a diversion—into a doubly exposed object...

the oldest thing we have ever seen

This image shows the afterglow of GRB 090423 (red source in the centre) and was created from images taken in the z, Y and J filters at Gemini-South and VLT (credit: A. J. Levan).

“This explosion provides an unprecedented look at an era when the Universe was very young and also was undergoing drastic changes. The primal cosmic darkness was being pierced by the light of the first stars and the first galaxies were beginning to form. The star that exploded in this event was a member of one of these earliest generations of stars,” said Dale Frail of the National Radio Astronomy Observatory.


Chankillo, Peru


The Thirteen Towers of Chankillo run from north to south along the ridge of a low hill within the site; they are relatively well-preserved and each has a pair of inset staircases leading to the summit.

The rectangular structures, between 75 and 125 square metres (807-1,345 sq ft) in size, are regularly spaced - forming a "toothed" horizon with narrow gaps at regular intervals.

About 230m (750ft) to the east and west are what scientists believe to be two observation points. From these vantages, the 300m- (1,000ft-) long spread of the towers along the horizon corresponds very closely to the rising and setting positions of the Sun over the year.

explaining it in a way the BBC never could....

What is reality ?



I really enjoyed this programme, particularly the part about the Double Slit experiment, but it went over it a bit too quickly for me. It's talking about what I'm interested in right now. Basically how we create our reality simply by observing it ????

"Scala Naturae"

"Vivarium"

"The Library for the Birds of Antwerp"

"I’m very interested in surrounding myself with the stuff that inspires me. I’m an artist who gets a lot from things, and in that way I’m very much a sculptor. I really love the world of stuff. I know a lot of artists who prefer to have very Spartan lives. Their inspiration is very much in their heads. They like clean, white, empty New York kinds of spaces. But I really like the surprising juxtapositions when you put things together on the bookshelf and when you start to collect things."

smell of books

Investigating the Smell of Old Books

April 16, 2008, 7:53 am

Researchers at Glasgow’s University of Strathclyde are studying the smell of old books to “sniff” out the chemical signs of aging.

Books are placed for 24 to 48 hours in a sealed chamber, where “material and compounds responsible for the odour from the books” will be extracted and analyzed, according to a university press release. Findings from the analysis will be used to determine the best practices for storing old books—and may also explain where that musty old-book smell comes from.

The study is being conducted by the university’s Department of Pure and Applied Chemistry in partnership with the British Library, on a grant from the Andrew W. Mellon Foundation.—Catherine Rampell

Dawn Scarfe



"Each listening glass possesses its own individual frequency and by inserting the smaller, teat-like end of the glass into the ear, the user is able to search out that frequency from their soundscape, success being announced when the glass vibrates in sympathy, and sounds loudly into the ear.
Dawn's listening glasses are modelled on resonators designed by scientist Hermann Helmholtz who used them to detect musical tones in, amongst other things, the 'howling of the wind, the rattling of carriage wheels, the rustling of leaves, and the splashing of water' (Helmholtz, 1863). Working with a glass blower, Dawn produced new resonators calibrated to distinct frequencies.
These resonators render tangible - visibly as well as audibly - our sensory system's own ability to isolate individual sounds. More than this, the resonators speak to Dawn's interest in resonance as a cybernetic phenomenon where a body picks up vibrations and resounds them, a system of feedback made more compelling when we recall that it is often described as 'sympathetic.'"
