I talked with Ms. Angelyn Marmeto about her study on the genetic interaction between BT corn and traditional maize varieties in the Philippines. Their team discovered the first evidence of natural cross-pollination, where insect-resistant traits from genetically modified corn were transferred to a native variety known as Silangan. We discuss how this gene flow happened, what it means for insect resistance, and the broader implications for agricultural biotechnology and biosafety in the country.

I talked with Mr. Gifford Jay Agudo about his study on land cover change and flood exposure in Quinali A Watershed, Albay. Using satellite remote sensing and flood modeling, his research tracks three decades of landscape transformation — from the loss of forests and brushlands to the rapid expansion of croplands and urban areas. The results reveal that urban growth is encroaching into flood-prone zones, nearly doubling exposure to flooding since 1990.

Scab diseases make fruits like mango, citrus, and sweet potato unappealing and unmarketable, but what if we could decode the fungus behind them down to its DNA? In this episode of Behind The Science Podcast, Dr. Leilani Sumabat-Dacones talked about her team’s discovery of the genes that make the fungus Elsinoë such an effective plant pathogen. Using bioinformatics, they analyzed fungal genomes to identify effectors and toxins like elsinochrome and melanin that trigger scab formation.

Dr. Evelyn Ame evaluates how the Gentleman’s Agreement — an informal management agreement among fishers — is holding up in practice for managing the stocks of aramang in Aparri, Cagayan. Using catch data, gear analysis, and participatory appraisal, Dr. Ame reveals that fishing mortality rates are much higher than natural mortality, and the current exploitation level (E = 0.66) already exceeds sustainable thresholds.

In this episode, I talked with Prof. Floirendo Flores about his research on fortifying rice with vitamin A. His study looked at how β-carotene can be better preserved and released using β-cyclodextrin microencapsulation. By testing different methods, the research shows how rice can be made more nutritious. This study also received the NAST PHL Outstanding Scientific Paper Award. Prof. Flores also shares his journey from chemical engineering to food science, the challenges of doing research during the pandemic, and his advice for young scientists in the Philippines.

In this episode, I talked with Dr. Angelo Macario about his study on how fishhook size affects catch variation, size selectivity, and bycatch in bottom-set longline fisheries targeting nemipterid fishes in the Philippines. His research shows that the choice of hook size plays a crucial role in determining the sustainability of fish stocks and the livelihood of small-scale fishers. Angelo also shares his journey as a researcher, the challenges of doing fieldwork in fisheries science, and his advice for aspiring scientists who want to make an impact in the field.
