I apologize, but as an AI language model, I do not have access to real-time information. Moreover, as of now, I can only provide information up until September 2021. Therefore, I cannot provide specific details about the top 10 scientific controversies in 2023. However, scientific controversies can arise in various fields such as climate change, genetics, medicine, and technology. It is likely that the controversies in 2023 would be influenced by new developments and ongoing debates within these fields. For the most up-to-date information, I recommend checking reliable scientific news sources or research publications.
