We are currently working on developing new projects to do. Right now we have 3 "pet projects"
1. Bacterial Warfare : Continuing on the old project. Have to start over, so need to do literature research all over.
2. "Dancing" Bacteria : Creating bacteria that will fluoresce when hit with a certain wavelength of light, and varying the wavelength of light to cause the bacteria to "dance"
3. Engineering Bacteria to create colored proteins to be used as an alternate food coloring.
This list will be updated as time goes on.
We are also affiliated with the Institute of Biological Engineering, IBE. You can visit their website to learn more.
