In this episode, we talk with Dr. Kerby Alvarez, a historian at the Department of History, University of the Philippines Diliman, about his study tracing the history of Philippine meteorology. Long before PAGASA existed, the Observatorio Meteorológico de Manila (OMM) — founded by Jesuit priests in 1865 — and its successor, the Philippine Weather Bureau (PWB) spent nearly a century turning typhoons into a subject of serious scientific study.

Drawing on archives in the Philippines, the US, and Spain, Dr. Alvarez shows how these institutions published hundreds of reports, built a regional network with weather observatories across Asia, and even got caught in a diplomatic dispute with Hong Kong's observatory in 1899. As a historian, he traces not just what these scientists discovered, but how their writing, data-keeping, and international collaborations were shaped by the political currents of Spanish and American colonial rule in the Philippines.

In this episode, we talk with Dr. Carlo Arcilla, a geologist and former director of the Philippine Nuclear Research Institute (PNRI) and the UP National Institute of Geological Sciences, about whether the Philippines is ready for nuclear energy. He explains why the Chernobyl and Fukushima accidents people associate with nuclear energy are not likely to happen Bataan. He also addresses the geologic hazard concerns in the BNPP. Dr. Arcilla also asserts that the Philippines is ready for nuclear energy but he will not advocate for it until the independent regulators are appointed.

In this episode, we talk with Mr. Jude Vito Custodio Agapito about his study on whether Project NOAH, the Philippine government's flagship disaster risk reduction program, actually saved lives. Using counterfactual analysis of hazard data from 1986 to 2024, the study compares fatalities and damages before and after operations research was embedded into the government's Pre-Disaster Risk Assessment system in 2014. While the cost of damages from typhoons and floods stayed consistent over both periods, average annual fatalities dropped by about 76%, from over 1,200 deaths per year to around 295, suggesting that the program may have saved more than 7,000 lives over the past decade.

In this episode, we talk with Ms. Eulah Araullo, Creative Lead at Canva and one of the Philippines' top educational content creators (@eulahexplains), about the design principles behind coats of arms, logos, and seals. We discuss the distinction between these three symbols, and how colonial history continues to shape Philippine seals today.

In this episode, we talk with Dr. Roy Joshua Gerona about the Doctors To The Barrio (DTTB) Program, what a day in rural healthcare actually looks like, the challenges of serving underserved communities, and why he chose this path.

In this episode, we talk with Dr. Renerio Gentallan Jr. about his study on the taxonomic identity of "lagundi", a group of medicinal shrubs long confused with one another due to decades of conflicting nomenclatural revisions. Despite lagundi-based products generating hundreds of millions of pesos in sales in the Philippines, the exact species being used and studied has remained ambiguous, with some specimens historically misidentified even in national pharmacopeia records. Using complete chloroplast genome sequencing alongside morphological and statistical analyses of over 2,000 herbarium specimens, the study clarified the species boundaries within this complex. The findings support reinstating Vitex elmeri as a distinct species and describe a new species, Vitex arvensis. The new species is a hybrid between V. bicolor Willd. and V. elmeri Moldenke, and also proposed as a new endemic species to the Philippines.

In this episode, we talk with Mr. Ramil Ramos about his study on flood and landslide susceptibility mapping in the City of Mati, Davao Oriental. Using a GIS-based Multi-Criteria Decision Analysis integrated with the Analytical Hierarchy Process (MCDA-AHP), the study generated hazard susceptibility maps and examined how urban expansion from 2017 to 2024 has increasingly encroached into high-risk zones.

We talk with Dr. John Jefferson Besa and Dr. Ella Mae Masamayor about their study on prolonged hospital stays among internal medicine patients admitted at the Philippine General Hospital. By reviewing the medical records of 386 patients admitted in 2019, prolonged length of stay was found in almost a fifth of emergency admissions and a quarter of elective admissions. They also discussed the factors associated with prolonged length of stay.📚Reference: Besa, J. J. V., Masamayor, E. M. I., Tamondong-Lachica, D. R., & Palileo-Villanueva, L. M. (2023).
