‘New era in digital biology’: AI reveals structures of ... - AAAS
Jul 29, 2022 · DeepMind says more than 500,000 researchers have already used the database since its launch last year. Hassabis predicted a “new era in digital biology” in which drug developers could go from AI-predicted structures of proteins important to any medical condition to using AI to design small molecules that influence those proteins—and ...
Quantum biology revisited | Science Advances
Apr 4, 2020 · Abstract. Photosynthesis is a highly optimized process from which valuable lessons can be learned about the operating principles in nature. Its primary steps involve energy transport operating near theoretical quantum limits in efficiency. Recently, extensive research was motivated by the hypothesis that nature used quantum coherences to direct ...
