Science Buddies: "Ask an Expert"

I am doing an adapted experiment from Science Buddies called "Bioluminescence: Investigating Glow-in-the-Dark Dinoflagellates". The experiment is clear and interesting, however, in order to do a science project on it, I need to relate it to a global issue or it just needs to have some global and personal engagement that gives purpose to my experiment.

Can anyone give me advice for what global engagement I could relate this to? I saw somewhere something about bioluminescence related to pollution, but I'm not sure.

If someone could help, that would be much appreciated.

Thanks.

Thanks for reaching out. My understanding is that bioluminescence can depend on the physiological state of the organisms, which implies that you could potentially use bioluminescence as a marker for monitoring marine ecosystem health. I also know that dinoflagellates, though not necessarily the bioluminescent ones, are responsible for harmful algal blooms (HABs). These are sometimes called "red tides," which is a term that's being used less frequently now for being misleading, but it could be a useful keyword for searches. HABs have gained attention for 1) being caused by pollution, specifically agricultural runoff that throws lots of nitrogen and phosphates into the water, and 2) choking out other organisms by consuming all the oxygen. Some also produce dangerous toxins that can affect human health, though I'm frankly not sure how many of the bioluminescent species are the ones making toxins.

Hope some of that was helpful.

Thanks so much for your quick response! that is all very useful, and I am sure that would be useful if I did an experiment on the change in bioluminescence due to pollution or an increase in certain minerals.

However, the experiment that I am looking at from Science Buddies looks into manipulating the circadian rhythms of the bioluminescent dinoflagellate, by varying the exposure to light and then measuring the bioluminescent intensity after a certain period of days. Could you possibly give me advice on some global engagement for this? I was thinking about how studying the factors which affect bioluminescence could support research into the future of biotechnology and the application of bioluminescent innovations, but I am not sure if that is strong enough. Any ideas?

Thanks a bunch for what you said anyways, really appreciate it.

Sorry about that. I still wonder if there's applications for marine health monitoring, since any work to understand the dinoflagellates could be used to further understand and improve our understanding of the ecosystem, but it feels like a stretch. Dinoflagellates (again, not always the luminescent ones) are critical symbionts of coral, so there could be applications in coral reef health. With some biotech finagling, perhaps your project results could be applied to the development of visual cues for coral monitoring on a day-to-day scale. I've been reading mentions of companies coming up with light bulbs or light sources using bioluminescent organisms, though a lot of them are using gene editing, which doesn't necessarily connect to the dinoflagellates specifically. But theoretically, if you were proposing a dinoflagellate-based energy-saving bio-lighting system, this research would have applications for how effective it could be during consumer use.
