Ep96 - Insect resistance in traditional corn: First report of cross-pollination with BT corn in the Philippines
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.📚Reference: Caasi-Lit, Merdelyn & Ocampo, Eureka & Salazar, Artemio & Paril, Jefferson & Novio, Bryan & Panabang, Bernard & Marmeto, Angelyn Marta.

Ep95 - Tracking 30 years of land cover change in Albay and its effects on flooding
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.📚Reference: Agudo GJ, Garcia J, Pulhin J, Mendoza J, Singson KV, Lagmay AMF, Cruz RV, Santiago J, Moises MA, Esquivel ALJ, et al. 2025.

Ep94 - Bioinformatics meets agriculture: Searching fungal DNA for genes behind fruit scabs
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.📚Reference: Cequeña RC, Sumabat-Dacones L. 2024. Presence of elsinochrome and other putative effectors in select genomes of the plant pathogen Elsinoë spp. based on in silico analysis.

Dr. Reginald Bernardo shares how his recent study uses the hunting behavior of the Philippine Eagle as inspiration for optimizing cosmological models that describe the expansion of the universe. 📚Reference: Bernardo RC, Enriquez EA, Mendoza R, Reyes R, Velasco AC. 2025.

Ep92 - Gentleman's Agreement management strategy for aramang in Aparri, Cagayan: is it effective?
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.📚Reference: Ame E, Laeno F, Villarao M. 2025.
