Google Unveils AI co-scientist to accelerate biomedical research

London, February 19, 2025 – Google has developed an advanced AI tool designed to serve as a virtual collaborator for biomedical researchers, the tech giant announced on Wednesday.

The tool, which leverages sophisticated reasoning capabilities, is intended to help scientists synthesize vast amounts of literature and generate novel hypotheses.

Tested by researchers at Stanford University and Imperial College London, the new AI co-scientist demonstrated promising results in an experiment on liver fibrosis, with all proposed approaches showing potential to inhibit key drivers of the disease. Google noted that while the findings are preliminary and require further validation, the tool has shown a capacity to enhance expert-generated solutions over time.

"While this is a preliminary finding requiring further validation, it suggests a promising avenue for capable AI systems... to augment and accelerate the work of expert scientists," a company spokesperson said. Google scientist Vivek Natarajan emphasized that the tool is meant to complement, rather than replace, human researchers. "We expect that it will increase, rather than decrease, scientific collaboration," he added.

The development is part of a broader trend of integrating AI into various professional fields. Following the success of models like ChatGPT, AI applications are increasingly deployed in tasks ranging from answering customer queries to carrying out legal research. Google's DeepMind, which has prioritized scientific innovation—its boss Demis Hassabis recently shared a Nobel Prize in Chemistry for technology developed at the unit—has been at the forefront of this movement.

As AI continues to transform the research landscape, tools like Google's AI co-scientist could play a key role in accelerating discoveries and driving breakthroughs in biomedical science. Further studies and experiments will determine the full potential and scope of the technology in supporting scientific advancement.
