The exhibition also included "In a Thousand Years". As a result of the show, Hirst was nominated for that year's Turner Prize, but it was awarded to Grenville Davey. Hirst's first major international presentation was in the Venice Biennale in 1993 with the work, "Mother and Child Divided", a cow and a calf cut into sections and exhibited in a series of separate vitrines. He curated the show "Some Went Mad, Some Ran
Formaldehyde concentrations of approximately 0.1 millimolar. Experiments in which animals are exposed to an atmosphere containing isotopically labeled formaldehyde have demonstrated that even in deliberately exposed animals, the majority of formaldehyde-DNA adducts found in non-respiratory tissues are derived from endogenously produced formaldehyde. Formaldehyde does not accumulate in the environment, because it is broken down within a few hours by sunlight or by bacteria present in soil or water. Humans metabolize formaldehyde quickly, so it does not accumulate, converting it to formic acid in the body. Formaldehyde was the first polyatomic organic molecule detected in the interstellar medium. Since its initial detection
