Summary: Artificial intelligence tools are becoming increasingly prominent in scientific research. A Nature survey of over 1,600 researchers worldwide found that more than half expected AI tools to be ‘very important’ or ‘essential’ in their fields in the next decade. However, scientists also expressed concerns about how AI is transforming research, including issues related to bias, fraud, and irreproducibility. The survey revealed that AI is already significantly influencing research across various domains, and scientists anticipate its continued growth in importance.
