I am writing a mock biotechnology research proposal for class and I don't know what I should make this research plan about.

Question

What are some of the most breaking scientific news, or diseases and issues in this field(biology preferred, or chemistry) that are currently having an impact on the world/mass populations and are worthy of researching further on and developing a biotechnology research proposal on?

I don't want to go too cliche and do cancer cells. I am thinking about stem cells, but what am I researching them for? What is the potential for them and where would I implement my research?

Any help is appreciated, thank you so much!
