The journal covers various aspects of biotechnology and bioengineering that could be important for health and the environment, and we welcome submissions in various relevant topics (see our aims and scope for a full list of topics). However, I would like to see more submissions on research that deals with a particular challenge in the world, such as how bioengineering can provide food for future generations with low environmental impacts, or how we can treat cancer, or even papers that introduce a new method in biotechnology. For another example, biofuels was a 'hot topic' last year, but I'd like to see the conversation move more towards biomaterials and materials with particular functions that could be beneficial to the environment, health, food production, and so on.
