The advanced specialties are gradually embracing artificial intelligence in complex activities, contributing to automation; biology, medicine, physics, chemistry, and ecology, as well as data analysis and perception and discovery of new opportunities. This paper on the numerous applications of AI explores how adoption of AI based methodologies is reinventing every scientific field. These areas involve artificial intelligence (AI) in enabling genomic, proteomic, and pharmaconomics as well as in formulating patient specificity drug discovery and patient-tailored therapeutic interventions that may fast-track medical outcome and diagnosis processes. AI in turn helps chemist and physicists to simulate complex systems, predict properties of molecules, and fine-tune chemical processes. By integrating AI into environmental science and space, application such as auto space mission, enhanced climate modeling and ecosystem dynamics are some of the achievements that resulted from the integration of AI. Further, the article includes some of the ethical issue with AI such as bias, privacy, and the limitations of current AI technology. A more significant level of work across disciplines, independent research initiatives, and laboratories powered by artificial intelligence is one of the possible scenarios. At any rate, artificial intelligence influences the external environment and acts as the driving force for changing the entire picture of science as well as pushing the boundaries of knowledge.
