Color transparency of the exterior of the headquarters of the Asilomar Conference Grounds in Pacific Grove, California. The grounds were the site of the 1975 Asilomar Conference on Recombinant DNA, an influential conference organized by Paul Berg (1926-2023) that considered the potential biohazards of, and need to regulate, biotechnology. The conference was a milestone in the history of science, marking the beginning of attempts to study the social implications of scientific progress and to mitigate against negative social impact.
