How Artificial Intelligence Can Revolutionize Science

How artificial intelligence can revolutionize science was an interesting article in the Economist. It cited two ways AI could accelerate scientific discovery: "The first is "literature-based discovery" (LBD), which involves analyzing existing scientific literature, using ChatGPT-style language analysis, to look for new hypotheses, connections or ideas that humans may have missed." (I mentioned some of the emerging tools in a previous newsletter: 052 - Genetic Judo, Young Blood, and Gray Hair). "The second area is "robot scientists," also known as "self-driving labs." These robotic systems use AI to form new hypotheses, based on analysis of existing data and literature, and then test those hypotheses by performing hundreds or thousands of experiments, in fields including systems biology and materials science." And for more on this topic, see my friend and colleague, Gary Kantor's excellent LinkedIn article: Can Generative AI Close The Knowledge Gap?
