In this episode, we talk with Alyzza Calayag about her study on the diversity, seasonality, and global distribution of viruses in the Arctic Ocean. Viruses play critical roles in ocean ecosystems but very little is known about viral communities in polar waters. Using water samples collected monthly for four years, the study identified 5,662 viral groups, found that viral abundance is 8-fold higher in summer than the rest of the year, and discovered that 42% of these Arctic viruses also peak in abundance in high-latitude regions of the Southern Ocean

In this episode, we talk with Ms. Jamila B. Abuda about her study on using machine learning to predict when landslides are likely to occur along a mountain highway in Benguet, Philippines. Being able to predict when landslides will happen is critical for early warning systems. The study tested five machine learning algorithms using only rainfall data and documented landslide events, and found that grouping landslide occurrences by rock type or lithology before training the models significantly improved prediction accuracy.

In this episode, we talk with John Albert M. Caraan about his study on Sporesight — an AI-powered computer vision tool that can automatically identify pollen developmental stages in eggplant in real time. Knowing the exact developmental stage of pollen is critical in doubled haploid technology, where microspores at the right stage are cultured in vitro to rapidly produce purebred plant lines.

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.
