🌱✨ A New Year, a New Celebration of Curiosity! ✨🌱

This January 2026, we highlight “Damayan” by Celine and Dennis Murillo, awarded 2nd Best Film in Indie-Siyensya, the pioneering science filmmaking competition of DOST-SEI. Their work reminds us how a nation is built, one mushroom at a time.

Their film draws attention to the hidden networks beneath our forests –the mycelial threads that connect and protect life. By bringing these unseen systems to light, Damayan shows how science and art together can deepen our understanding of ecology and spark curiosity about the world we often overlook.

“Thank you very much, Constantino Foundation! It was a lovely afternoon spent learning about history, poetry, art, climate change, street names, the bicycles in revolution, kickass heroines, and much more! Renato Redentor Constantino’s talk and Renato Senior’s book A Past Revisited really got under my skin. Maraming salamat!”

“A Past Revisited was both a revelation and a challenge. It made us see the familiar narratives of Philippine history in new and unsettling ways. It invited us to ask deeper questions—about power, about colonial legacies, about the struggles and aspirations of our people. And it also gave us a sense of responsibility: to carry history forward not just as memory, but as a guide for action and transformation.”

Dr. Chas M. Navarro
Commissioner, National Historical Commission of the Philippines (NHCP)

“At a low point in my life, I received a note from Letizia Constantino, unsolicited advice that encouraged me to keep writing. I never got to thank her personally for that pat on the back; this column is belated gratitude.”

Ambeth R. Ocampo
Historian, An excerpt from his column in Philippine Daily Inquirer
"Letizia Roxas Constantino, historian", 2025 June 06
“Frequented the area in the early ’80s because of Popular Bookstore (small door, beside the gate of Mapua High School), the only one that carried engineering books required for our course. It was still Martial Law… One buys … dangerous reading materials afraid of the Secret Marshals who were then infamous for salvaging (tokhang in the time of tatay digong) petty criminals and activists. Across Mapua High then was a parking lot of mini buses – now the Manila Grand Opera.”

“We have been so wonderfully blessed in the past week by the presence of tremendously inspiring people, one of them, the one who likes to “shake trees”, is Sir Renato Redentor Constantino who moved the entire plenary to feel, think, and act… people couldn’t help but share and talk about the presentation. I told Sir Red that by the second day of the event, people realized there were ‘deeper commitments than professionalism.’”

"... A Past Revisited sparked a different kind of revolution, one that urged Filipinos to view history through our own eyes and experiences. Thank you very much to our dear friend, ABS-CBN’s Karmina Constantino, a resident of San Juan, for inviting me to be part of this historic occasion."
