Newsletter: UP Study Maps Flying Fox Movements to Support Conservation Efforts

[THIS IS A PRESS RELEASE]

By: Eunice Jean C. Patron

Flying foxes are large fruit bats that primarily feed on fruits and flowers. They are highly mobile, traveling long distances in search of seasonal food sources. Some have been recorded flying more than 20 kilometers from their roost (sleeping area) in a single night to forage, easily crossing islands and even international borders. Over the course of a year, flying foxes can travel more than 6,000 kilometers, making them among the most far-ranging bats in the world. They often fly too far and too fast for humans to accurately follow their movements.

The Philippine eagle, the country’s national bird, is one of the largest and most powerful eagles in the world. Susceptible to habitat destruction and fragmentation, it is currently listed as Critically Endangered by the International Union for Conservation of Nature, making it one of the most threatened birds globally. To help ensure its survival, scientists have carried out a captive breeding program in protected facilities for over 30 years as part of conservation efforts.

Newsletter: UP MSI and Partners Launch Kalalawdan Fellowship Program Batch 2 to Strengthen Science-Based Maritime Governance in the Philippines

[THIS IS A PRESS RELEASE]

By Sofia Guanzon, Microbial Oceanography Laboratory, UP MSI

A new cohort of researchers, government professionals, and local policymakers from across the Philippines will soon convene under the Kalalawdan Fellowship Program as Project NEXUS 2.0 expands efforts to strengthen the connection between marine science and policymaking in the country. As an archipelagic and maritime nation, pursuing and strengthening science-based development is not only needed but necessary. However, attaining this will require policy reforms that are both science-enabling and science-enabled. These are the challenges faced by the Lawod Fellows as they embark on a seven-month training under the Fellowship program.

Newsletter: How Land Use Shapes the Viruses Mosquitoes Carry, UP Study Finds

[THIS IS A PRESS RELEASE]

By: Eunice Jean C. Patron

Virome sequencing performed on Aedes aegypti and Ae. albopictus used in the study in 2018 revealed

sequences belonging to vertebrate-associated and insect-specific viruses (Asin et al,. 2025).

Mosquitoes such as Aedes aegypti and Aedes albopictus, which are known to transmit diseases like dengue, Zika, and chikungunya, may carry more than just viruses that affect humans. They also host insect-specific viruses that do not infect people, some of which may even inhibit the multiplication of disease-causing viruses. This implies that mosquitoes can serve as valuable tools for detecting both known and emerging viruses that may impact public health.

Newsletter: Filipino Scientists Develop Novel Method to Refine Mathematical Models and Identify Drug Targets

[THIS IS A PRESS RELEASE]

By: Eunice Jean C. Patron

Biological processes like the Wnt signaling pathway—which regulates crucial development and helps keep the body’s tissues functioning normally and in balance—are often described by scientists using mathematical maps called reaction networks, which serve as the foundation of mathematical models. These allow scientists to examine and compare models based on their structure alone without needing or with minimal specific parameter values. Although several Wnt models exist, they differ in how they represent the same underlying biological system. To address this, Filipino mathematicians introduced a new method to find the common ground between these different maps.

According to the International Agency for Research on Cancer (IARC), the Philippines recorded nearly 189,000 new cancer cases and more than 113,000 cancer-related deaths in 2022. Globally, IARC also projects that the number of new cases will rise to over 35 million by 2050, which is a 77% increase from 2022 figures. Meanwhile, the 2025 Philippine National Cancer Summit reports that more than 180,000 new cases are diagnosed each year and cancer is estimated to cause over 300 Filipino deaths daily. These alarming statistics highlight the urgent need for continued research and innovation in cancer treatment.

Newsletter: UP Researchers Record First Measurement of Elusive Light Shift in Low-Loss Dielectric Materials

[THIS IS A PRESS RELEASE]

By: Eunice Jean C. Patron

A laser reflecting off glass looks like it follows the mirror rule—angle in equals angle out. But with sensitive tools, the spot shifts slightly, no bigger than a strand of hair. This elusive effect, called the Goos–Hänchen (GH) shift, was recently explored by scientists from the UP Diliman College of Science (UPD-CS) in materials that barely absorb light—such as those used in semiconductors and photonics.

[THIS IS A PRESS RELEASE]

By: Dr. Jelaine L. Gan

Reforestation activities typically involve planting trees in degraded areas. However, tree planting is resource-intensive, requiring labor for the planting and more importantly nurturing of the seedlings, and may be expensive and limited by seedling supply. Moreover, there is always a question of whether the right plant species (i.e., native rather than non-native economically important species) are being planted to benefit biodiversity.
