Ang mundo ng social media ay nagiging isang mahalagang mapagkukunan ng data para sa biodiversity at conservation, lalo na para sa mga mailap o di gaanong kilalang species tulad ng Philippine tarsier, na isang primate din tulad ng mga unggoy at tao. Sa kabila ng katanyagan nito, limitado pa rin ang impormasyon tungkol sa kung saan ito nakatira at kung paano ito kumikilos sa wild.

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.

Maraming ibon ang umaasa sa tree cavities, o mga butas ng puno, para mapugaran at magpalaki ng kanilang mga sisiw. Ang mga woodpecker, na kilala bilang pangunahing excavator, ay kayang lumikha ng kanilang sariling mga butas. Sa kabilang banda, ang mga non-excavator—tinatawag ding secondary cavity nesters—ay nakadepende sa mga likas o dati nang nahukay na mga butas para sa kanilang reproduksyon. Ang mga ibong ito ay nahaharap sa mga hamon tulad ng kakulangan ng angkop na mga butas, na maaaring maglimita sa paglaki ng kanilang populasyon.

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.

Scientists from the University of the Philippines – Diliman College of Science (UPD-CS) have developed a new semiconductor structure that could lead to more affordable and reliable terahertz (THz) technology—used in applications ranging from medical imaging to high-speed wireless communication.
