Newsletter: Bird poop to the rescue: Using bird perches for forest regeneration

[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.

The Philippines is often hit by tropical cyclones (TCs), which bring heavy rainfall that can cause floods and landslides. More often than not, the patterns of TCs repeat. For instance, if a typhoon with a certain amount of rainfall passes through Central Luzon, a similar typhoon that will pass through Central Luzon again in the future is likely to have the same amount and distribution of rainfall.

Newsletter: UP Scientists Uncover Influence of Reflected Shock Waves on Plasma Behavior

[THIS IS A PRESS RELEASE]

By: Eunice Jean Patron

Scientists around the world have extensively studied the expansion of laser-produced plasma (LPP) and the shock waves it generates in a background gas. However, little attention has been given to how the reflected shock wave—one that bounces back from a surface—affects the expanding plasma, despite its potential impact on LPP behavior.

Dr. Rommil Emperado, Dr. Myles Allen Zosa, and Dr. Wilson Garcia of the University of the Philippines – Diliman College of Science’s National Institute of Physics (UPD-CS NIP), together with Dr. Lean Dasallas of the UPD-CS Materials Science and Engineering Program (MSEP), analyzed the interaction of copper LPP with surrounding gas through the direct simulation Monte Carlo (DSMC) method, which simulates particle behavior using random numbers.

Newsletter: UP Scientists Identify Plant Boosting Bacteria in Bamboo and Corn

[THIS IS A PRESS RELEASE]

By: Eunice Jean C. Patron

Farmers usually use chemical fertilizers to grow their crops, but these can be expensive and may harm the environment. A more efficient and cheaper alternative is the use of specific microorganisms called plant growth-promoting bacteria (PGPB). PGPB help plants absorb more nutrients and produce growth hormones that boost crop production. Using PGPB as biofertilizers can provide the same benefits as chemical fertilizers—without the harmful effects.

Newsletter: Recent UP Study Finds Social Media a Valuable Tool for Understanding Philippine Tarsiers

[THIS IS A PRESS RELEASE]

By: Eunice Jean C. Patron

The world of social media has become an increasingly important source of data for biodiversity and conservation, especially for rare or little-known species such as the Philippine tarsier. However, despite its popularity, there is still limited information about where it lives and how it behaves in the wild.

Maria Sabrina Tabeta and Simeon Gabriel Bejar of the University of the Philippines – Diliman College of Science’s Institute of Biology (UPD-CS IB) explored public posts and group posts on Facebook that mentioned Philippine tarsiers.

Newsletter: Biologists Assess Importance of Tree Cavities for Forest Birds in Subic, Philippines

[THIS IS A PRESS RELEASE]

By: Eunice Jean C. Patron

Many birds rely on tree cavities, or tree holes, for nesting and raising their young. Woodpeckers, known as primary excavators, can create their own cavities. In contrast, non-excavators—also called secondary cavity nesters—depend on naturally occurring or previously excavated cavities for reproduction. These birds face challenges such as a scarcity of suitable cavities, which can limit their population growth. To protect them, it is important to understand the specific nesting needs of each bird species and how they interact with one another. In regions like the Philippines, where forests are vulnerable to change, there is still limited information on how these birds nest and how they are connected.

Newsletter: UP Researchers Predict Antimicrobial Resistance Using AI Models

[THIS IS A PRESS RELEASE]

By: Eunice Jean Patron

Escherichia coli (E. coli) is a common bacterium that lives in the intestines of animals and humans, and it is often used to identify fecal contamination within the environment. E. coli can also easily develop resistance to antibiotics, making it an ideal organism for testing antimicrobial resistance—especially in certain agricultural environments where fecal material is used as manure or wastewater is reused.

Mindoro is home to a unique bounty of endemic mammalian wildlife found nowhere else on Earth. This includes the famous tamaraw, the Mindoro warty pig, and the humble Mindoro shrew. Now, three more species are added to the list, thanks to the recent discovery of Philippine forest mice—all belonging to the Apomys genus.

Groundwater—water trapped beneath the Earth's surface—is a resource that may be out of sight, but it is certainly not out of mind for many Filipinos. This invisible resource is vital for everyday life, especially in agriculture, where it provides the lifeblood for irrigation. However, as our demand for food grows and technology allows us to tap deeper into the Earth, groundwater faces an urgent crisis of over-extraction and contamination that demands immediate attention.

Newsletter: UP Scientists Explore Marine Microbial Genomes from Mabini, Batangas

[THIS IS A PRESS RELEASE]

By: Eunice Jean C. Patron

Submarine groundwater discharge (SGD) is a process in which groundwater from land seeps into the ocean, transporting freshwater, nutrients, metals, and even pollutants into marine ecosystems. The diverse microbial communities in these SGD sites make them hotspots for biological and chemical activity, playing a crucial role in maintaining ecosystem balance. Studying these microorganisms helps scientists not only understand their impact on marine ecosystems, but also explore their potential applications in medicine and biotechnology.

According to the International Agency for Research on Cancer, lung cancer is the leading cause of cancer-related deaths worldwide, with nearly 2 million deaths. In the Philippines in 2022, it recorded 23,728 new cases—making it the second most common cancer after breast cancer—and caused 20,953 deaths, the highest among all cancer types. Non-small cell lung carcinoma (NSCLC) is the most common type of lung cancer, accounting for more than 80% of cases. Experts say that late diagnosis and challenges in treating late-stage cases are the main factors affecting the cancer mortality rate, including NSCLC.

Newsletter: Tapuy rice wine fermentation yields possible anti-aging superfood

[THIS IS A PRESS RELEASE]

Filipino researchers have found a way to optimize the traditional procedure for making Philippine rice wine or “tapuy” to produce a potential superfood rich in anti-aging compounds and antioxidants. 

“Tapuy” rice wine starts out as a mixture of black and white glutinous rice (A), which is fermented using a starter culture or “bubod.” After a month, the solid residues from the fermentation process or “lees” (B) are filtered out and usually discarded. CREDIT: Bragais and Medina, 2025

Gold nanostructures have unique properties that depend on their shape. Branched structures resembling tiny corals, particularly gold nanocorals, have been proven valuable in applications such as chemical detection (SERS-based), fluorescence imaging, and catalysis. However, their production often involves complex, costly, and environmentally harmful processes.

The World Health Organization (WHO) aims to eliminate sexually transmitted infection (STI) epidemics as significant public health threats by 2030. One of the four main non-viral and curable STIs, trichomoniasis, stays persistent, affecting 156 million out of 376 million individuals aged 15–49 in     . About 70–85% of persons with trichomoniasis show no signs of infection, highlighting the urgent need for accurate, fast, and accessible detection of Trichomonas vaginalis, the parasite that causes the infection.
