What are the research hotspots of molecular biology and genetic engineering at present?

I am also studying biology. I'm depressed. How can you not know the direction in the future? 1, avian influenza 2, stem cell research 3, food health, such as Sudan red incident, inferior milk powder, etc. 4. Ecological agriculture 5. Biological problems involved in the construction of new countryside, such as the utilization of rural biogas. 6, SARS 7, biological engineering, such as cloning, genetic engineering, fermentation engineering, cell engineering, etc. 8, AIDS 9, immunity, such as skin transplantation. 10, human health problems, such as weight loss and food hygiene. 1 12, related environmental issues, related biological achievements that won the Jobert Prize. Molecular biology should be a hot topic.
