Questions & Answers

Q: How do shrimp use bioluminescence to escape predators?

Shrimp produce a blue light using a protein called luciferase to distract predators long enough to escape, showcasing a unique defense mechanism in the deep sea ecosystem.

Q: What is the significance of using synthetic biology for disease diagnostics?

Synthetic biology offers the potential to create innovative solutions like a simple antibody detection test that can be performed anywhere using basic equipment like a mobile phone camera.

Q: How does the molecular traffic light concept work for detecting antibodies?

By combining proteins that emit blue and green light, researchers create a system where the presence of specific antibodies causes a color change, indicating the presence of a disease biomarker.

Q: What are the challenges researchers face in translating basic research to real-world applications?

Challenges include ensuring the test is cost-effective, accessible, and scalable for global use, as well as navigating issues like patentability and the open-source nature of synthetic biology.
