These living drawings by Hunter Cole are made with bacteria that have genes for luminescent proteins inserted in them, brushed like glowing paint on the canvas of an agar plate.

Previously: Check out the elegant geometry of these 3D viral structures, and the “platonic solids” they create!Laura Splan, from the series Doilies, 2004 (source)
“Doilies is a series of computerized machine embroidered doilies. The design of each doily is based on a different viral structure [SARS, HIV, Herpes virus, Influenza virus, and Hepadna/Hepatitis B virus, respectively]. The lace doily has traditionally referenced designs and motifs from nature. Furthermore, these decorative objects would be heirlooms, handed down from one generation to the next. The work explores the “domestication” of microbial and biomedical imagery. Many recent events, epidemics, and commercial products have brought this imagery into our living rooms, kitchens, and bathrooms. Bio-terrorism, SARS, and antibacterial soaps alike have all heightened our awareness of the microbial world. Doilies serve as a metaphor for the way we have adapted our everyday lives to these now everyday concerns. Here domestic artifacts and heirlooms manifest the psychological heredity of our cultural anxieties.”

A diffraction image of a protein crystal, which is created by using a particle accelerator to irradiate the protein with X-rays. This technique enables scientists to see internal structures of complex protein molecules such as enzymes. (via)

Faraday hexagons by stephen w morris
Parametric “Faraday” surface waves on the surface of a fluid shaken vertically. For shallow layers of moderately viscous fluids, the waves form a honeycomb lattice.

Square Chladni plate 5875.5 Hz by stephen w morris
A thin metal plate shaken vertical by a post in the centre will vibrate in a certain mode pattern. The pattern can be made visible by sprinkling white sand or salt on the plate. The grains are shaken off the areas where the plate is moving most violently (the anti-nodes) and collects on the non-moving regions (nodal lines). This technique was originally invented by Robert Hooke, but made famous by Ernst Chladni in the late 18th century.
