𝗧𝗵𝗲𝗿𝗲 𝗮𝗿𝗲 𝗿𝘂𝗹𝗲𝘀 𝗶𝗻 𝗴𝗶𝗿𝗹 𝗳𝗿𝗶𝗲𝗻𝗱𝘀𝗵𝗶𝗽𝘀. 𝗕𝘂𝘁 𝘄𝗵𝗼 𝗺𝗮𝗱𝗲 𝘁𝗵𝗲𝗺?

We call it the “𝗴𝗶𝗿𝗹 𝗰𝗼𝗱𝗲”, those unspoken expectations about loyalty, boundaries, trust, and how we show up for our friends.

But where do these rules come from? How do friendship groups enforce them? And what happens when someone breaks them?

A qualitative study involving Filipino adolescent girls found that the girl code develops through shared experiences and repeated interactions, rooted in values such as respect, compassion, loyalty, and trust. The study also explored how these unwritten rules can shape friendship, emotional well-being, conflict, and belonging.

Curious about what the researchers found?

𝗪𝗵𝗮𝘁 𝗶𝗳 𝗯𝗶𝗼𝗽𝗹𝗮𝘀𝘁𝗶𝗰 𝗰𝗼𝘂𝗹𝗱 𝗯𝗲 𝗺𝗮𝗱𝗲 𝘀𝘁𝗿𝗼𝗻𝗴𝗲𝗿 𝘄𝗶𝘁𝗵𝗼𝘂𝘁 𝗴𝗶𝘃𝗶𝗻𝗴 𝘂𝗽 𝗶𝘁𝘀 𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝘁𝗼 𝗯𝗶𝗼𝗱𝗲𝗴𝗿𝗮𝗱𝗲?

That’s what this study explored using cornstarch-based bioplastic reinforced with pineapple leaf fiber (PALF), polyvinyl alcohol (PVA), and zinc oxide (ZnO).

The results showed that different formulations performed better for different goals.

𝗙𝗼𝗿 𝘀𝘁𝗿𝗲𝗻𝗴𝘁𝗵: Sample C2 recorded a 0.76 MPa tensile strength and 6.40% elongation at break, making it the strongest formulation tested.

𝗙𝗼𝗿 𝗱𝗲𝗴𝗿𝗮𝗱𝗮𝗯𝗶𝗹𝗶𝘁𝘆: Sample C3 had the fastest degradation rate, with a 27.24% loss in weight from its initial weight during the soil degradation test.

In other words, making a bioplastic stronger and making it more degradable may require finding the right balance of materials.

It’s a small but interesting look at how agricultural materials like pineapple leaf fiber and cornstarch could contribute to the development of more sustainable materials.

Marking the fourth session of Sinaya’s AI Assisted Research Mentoring Workshop series, participants engaged in interactive, hands-on activities focused on leveraging generative AI usage for ethical research creation and mentoring. The culminating session was held on January 23, 2026 at the Dr. Andrew L. Tan Data Science Institute, McKinley Hill, Bonifacio Global City, Taguig City.

Led by Dr. Feorillo A. Demeterio III, Executive Director of the DLSU Research Grants and Management Office, the workshop series offered practical and grounded strategies on integrating AI across key stages of the research process, from developing research questions and navigating literature reviews to refining academic manuscripts and supporting scholarly publications.

During the sharing session, participants openly discussed ongoing concerns about critical thinking in the context of AI use in education, emphasizing the need to strike a balanced and guided approach. One participant shared, “Rather than being afraid of students using AI, we need to focus on guiding them.” Another added, AI is not something “to think for us, but to think with us.” Together, these reflections highlighted a shared understanding that AI, when thoughtfully integrated, can support learning while preserving the central role of educators.

As the workshop series concluded, participants expressed a shared sense of confidence and openness toward working with technology, embracing AI as a partner in their ongoing research journeys. The experience fostered a mindset of ethical, innovative, and collaborative engagement with AI-supported research writing, as educators, researchers, and professionals collectively reflected on how technology can meaningfully support scholarly work.
