the 3rd GRAND PRIZE
Awarded
to "Mother
and Child"
|
Two
English artists Heather ACKROYD and Dan HARVEY for the exemplary work carried out in
collaboration with the teams of biochemists from the Institute of Grassland and
Environmental Research (IGER) in Wales, that led them to the production of grass
photosynthetic photographs.
These
two artists use the photosensitive properties of grass to produce photographic
images thanks to photosynthesis. In projecting a black and white negative onto
the surface of young grass grown from seed, a positive photographic image
emerges slowly over days, becoming increasingly visible as the blades of grass
mature. These photosynthetic photographs exist as living organic prints for a
time depending on lighting and atmospheric conditions.
The
artists have also been involved on work that investigates reasons for plant
death and its prevention. Together with the scientist of IGER, they have
identified how to control genetically the enzyme that degrades the green pigment
chlorophyll, contributing to the yellowing of senescent leaves. By modulating
the expression of the gene, the scientists can alter aging behavior and even
stop it all together. They have consequently managed to render permanent some of
their work.

the 3rd PROMOTION PRIZE
Awarded to "A DETECTIVE STORY IN THE BUTTERFLY EYE"
|
A
Japanese biologist, Kentaro ARIKAWA, who set out to prove that the eye of the butterfly
could perceive colors, from red to ultraviolet.
Intrigued
from the age of 7 by the butterfly's distinct attraction to the color red, Kentaro Arikawa sought to understand the way in which their visual system
operates. He found out that the butterfly's eye contained five types of spectral
receptors. The receptors are sensitive in the blue, green, yellow, red and white
wavelength regions. This suggests that butterflies may have a penta-chromatic
color vision that could even inspire artists.

Awarded
to "THE SECRETS OF EGYPTIAN BLUE AND GREEN PIGMENTS"
|
A
French chemist Sandrine PAGES-CAMAGNA for her work on the blue and green pigments
of Egypt during the IIIrd millennium BC.
Through
interdisciplinary research, between chemistry and the history of art, Sandrine Pages-Camagna scientist at the Laboratoire de Recherche des Musées de France,
worked at understanding the origin of color in such pigments and at
rediscovering the manufacturing processes which allowed Egyptian artists to
produce synthetic pigments.
