- Conducted a brainstorming session based on the specific track.

- Wu Di and Kong Kexuan: Focused on biomanufacturing using genetic oscillators to produce ethanol and isobutanol.

- Wang Chen, Cao Xiaoran, He Zihang, Xiao Mingyang, Cao Yue, Lv Siyuan, Zhang Xiaohan, Yu Haoyang, and Chen Jinpeng: Explored new therapies for Alzheimer's disease, pancreatic cancer, etc.

- Prof. Huang’s suggestion: Consulted Prof. Chen Ming and voted for the preferred project.

- Selected the project topic: "Production of ethanol and isobutanol based on gene oscillators."

- Brainstormed project details.

- Divided writing tasks for the iGEM project application.

- Based on the input from Prof. Chen Ming and team voted, the topic "Production of ethanol and isobutanol based on gene oscillators" was selected.

Writing task allocation:

- Background: HP group

- Project design: Dry lab

- Theoretical basis: Wet lab

- Wet lab, dry lab, and HP groups conducted interviews and recruited new team members.

- Each group prepared questions and conducted interviews.

- Full team meeting.

- iGEM overview (Wang Chen):

1. Timeline & process for iGEM defense.

2. Medals, Villages, and individual awards.

3. Introduction to the offline Grand Jamboree in Paris.

4. Competition fees.

- Introduction of advisors:

1. Prof. Huang Wenwen, Prof. Jin Mengdi, and advisor Zheng Ximeng share their experiences.

2. Prof. Huang emphasized the importance of planning and adhering to deadlines.

3. Prof. Jin highlighted the availability of lab space.

4. Advisor Zheng Ximeng shared insights into building a complete project narrative and leveraging domestic and international resources.

- Consulted teacher Lian regarding the experimental scheme for longevity yeast.

- Explored advanced knowledge of ethanol and isobutanol production.

- Acknowledged the challenges in building the genetic oscillator.

- Considered collaborating with Zhouzou’s lab for yeast strains containing oscillators.

- Switched to the Fashion & Cosmetics Village.

- The initial idea of ethanol and isobutanol production was derived from an optogenetics paper. However, combining two papers without significant innovation led us to consider alternatives.

- Meeting with cosmetic expert Dr. Qiao.

- Ethanol and isobutanol were unsuitable for cosmetics. Dr. Qiao suggested exploring glycolipids and preservatives as alternatives.

- Set up the laboratory and conduct access training.

- Began culturing yeast containing the oscillator.

- Prepared for exams

- Student leaders' meeting.

- Planned summer vacation tasks for the wet lab, dry lab, and HP groups.

- Student leaders' meeting.

- Reviewed recent work and discuss project issues.

- Consulted Prof. Chen for feedback on production choices and project specifics.
