Best STEM ideas and topics?

So for my third year engineering class, I have to present three possible topics for me to research all year long on the first day of school. I am pretty much interested in everything, but I need a topic that I can research all year long, and can be related to any aspect of STEM. It should also be a somewhat new idea/invention/ creation that I can learn about and hopefully work upon in my own way. If you guys have any ideas or topics that you would like to share, please tell me! thanks :smiley:

gizmag, gizmodo, and other online magazines have some really cool topics and ideas that might help you get started. There is a large range of topics that these magazines cover, including new tech, new research, and alot of other things. Take a look around!
