    1. There was no contaminant in the water, but rather a bacterial infection amongst our fly population.

  1. Very interesting experiment and good job presenting! I was curious about how your water vitals were contaminated and how you could have prevented that outcome!

    1. Thank you! There was a bacterial infection in our fly population that impacted the water vials we had intended to use for our negative control. Basically we didn’t have enough larvae to test our water vials. 🙁

  2. Was the bacterial infection that killed a lot of your larvae a result of the contaminated water?

    1. We don’t know what caused the bacterial infection in our flies, but it pretty much killed many of our adult flies and/or prevented them from producing more larvae.

  3. Great Poster and Great Presentation!! I know that you discussed what Heparin does and why you chose to specifically study this compound, but were there any other compounds or approaches that you would have liked to also look at? Are there other compounds that exhibit this same property but are yet to be tested?

    1. Thank you! We did look at other compounds in our preliminary research before landing on heparin. For example, I was interested in a compound found in broccoli (that I now can’t remember the name of). And I’m not sure if there are other compounds similar to heparin… probably, but I didn’t take a look at any in particular.

    1. The water itself was not contaminated, but our fly population had an infection that caused many of the adults to die or not produce larvae for some reason. Either way, it impacted our experiment because without larvae, we could not perform the number of trials we wanted to (including the ones with water vials).

  4. How did you ensure that your compound was distributed evenly throughout the fly food? What does it mean if you have a datapoint above two standard deviations from the mean?

    1. There was no way to ensure that the compound was completely evenly distributed, but we did our best by mixing the compound into the food while the food was still hot and in its liquid form. For a data point two SDs above the mean, we would consider that compound a potential radiation protectant, since the percent survival would be really high. Radiation alone kills about 50% of larvae, so if a lot more than 50% of them are surviving, the compound could be helping keep them alive.
