British artist Andrew Carnie has brought two unusual works to the Traces of Humanity exhibition in Gibraltar, using pollen and mosquitoes to explore the human immune system and the relationship between art and science. "I was doing a piece for an immunology project, based in Portugal, with five or six other artists, making work about the immune system," Carnie told the Chronicle. "That plays a big part in the immune system, distributing liquids and everything. And so the immune system protects us against various things." To create the finished works, Carnie crushed the mosquitoes before applying the material through cardboard stencils using glue.
