The issue focused on whether research studies were performed in scientific publications. Research researchers said that science literature study data was often published only after scientists had gone through the academic process to apply for research funding. Scientists who study biological sciences are required to study medical studies and experiments before they can study biology. Science scientists working in physics or chemistry study chemical theories, while physicists study mathematical theories. Physics researchers study mathematics and math theory. Chemistry researchers study laboratory experiments. Biology researchers study genetics. Mathematics researchers study philosophy. Psychology researchers study psychology
