In this episode, we are joined by Mikael Angelo Francisco — an award-winning science journalist, the co-founder and editor-in-chief of FlipScience.ph, host of the Ask Theory Podcast, and a leading voice in Philippine science media — for an in-depth conversation on the evolving landscape of science communication in the Philippines. We discussed the strategic value of podcasting, the common errors scientists make when addressing non-specialist audiences, and the shared responsibility of journalists and researchers in combating misquotation and misinformation.🤝Behind The Science Podcast is presented to you by Marine & Earth Science Learning Hub, UP Resilience Institute, The Philippine Agricultural Scientist, The Philippine Journal of Fisheries, and SciEnggJ.

Reuploading this old lecture I made...Tsunami or typhoon? Which one built the mysterious island off the coast of Lumaniag village in Batangas? That's the question researchers from UP Diliman set out to answer.In this episode, we dive into how researchers from UP Diliman solved this coastal detective story. By combining field measurements, uranium-thorium dating of coral boulders, historical typhoon records, and interviews with village elders to piece together how typhoons in the 1960s and 70s built an entire island from scratch. Here's the twist: that storm-built island is now protecting the very community it once threatened.📚Reference: Gallentes AT, Manglicmot MT, Gong SY, Hu HM, Shen CC, Siringan FP. 2021.
