The lives and careers of the Filipino Ilustrados in Madrid in the last two decades of the 19th century are well known. Figures such as Dr José Rizal, General Antonio Luna, Juan Luna, and Marcelo H. del Pilar are familiar to many Filipinos. However, the career of Dr. Francisco Tongio Liongson is less so. Like General Luna, Liongson trained as a scientist at the Universidad Central de Madrid, where he earned his doctorate, and pursued postdoctoral training at the Institut Pasteur in Paris. As with many Filipino scientists who studied overseas, he returned home with the intention of establishing laboratories and teaching future medical students, had the revolution not occurred and Philippine independence been secured.

Nakadiskubre ang isang lokal na mamamayan ng Solana, Cagayan (Hilagang Luzon) ng pinakaunang fossil ng bungo ng Stegodon. Ang Stegodon ay isang extinct na animal na malayong kamag-anak ng mga modernong elepante. Ang natuklasang milyong-taong-gulang na bungo ay ang paksa ng isang pagsusuri ng mga paleontologist mula sa UP Diliman College of Science (UPD-CS) at University of Wollongong sa New South Wales, Australia.
