				<p><span style="font-weight: 400;">Ang Haring Ibon (</span><i><span style="font-weight: 400;">Philippine eagle</span></i><span style="font-weight: 400;">), na pambansang ibon ng Pilipinas, ay isa sa pinakamalalaki at pinakamakapangyarihang agila sa buong mundo. Dahil madali silang maapektuhan ng pagkasira at pagkakawatak-watak ng kanilang tirahan (</span><i><span style="font-weight: 400;">habitat destruction and fragmentation</span></i><span style="font-weight: 400;">), kasalukuyan itong nakatala bilang </span><i><span style="font-weight: 400;">Critically Endangered </span></i><span style="font-weight: 400;">sa </span><i><span style="font-weight: 400;">International Union for Conservation </span></i><i><span style="font-weight: 400;">of Nature</span></i><span style="font-weight: 400;">. Dahil dito, itinuturing ito bilang isa sa mga pinakananganganib na ibon sa buong daigdig. Upang masiguro ang kaligtasan ng kanilang lahi, mahigit 30 taon nang nagsasagawa ang mga siyentipiko ng programang </span><i><span style="font-weight: 400;">captive breeding </span></i><span style="font-weight: 400;">sa mga protektadong pasilidad bilang bahagi ng mga gawaing pang-konserbasyon. </span></p><p> </p><p><span style="font-weight: 400;">Upang suriin ang DNA ng 35 Haring Ibon na nasa ilalim ng pangangalaga ng </span><i><span style="font-weight: 400;">Philippine Eagle Foundation </span></i><span style="font-weight: 400;">(PEF), nakipagtulungan ang isang pangkat ng mga eksperto sa pamumuno ni Dr. Cynthia Saloma ng </span><i><span style="font-weight: 400;">University of the Philippines &#8211; Diliman College of Science&#8217;s National Institute of Molecular Biology and Biotechnology </span></i><span style="font-weight: 400;">(UPD-CS NIMBB). Kasama niya sa pag-aaral sina Dhan Mikhail Perdon, Franchesca Pascual, Francis Tablizo, Carlo Lapid, John Michael Egana, Renato Jacinto Mantaring, Kris Punayan, Shiela Mae Araiza, Jo-Hannah Llames, at Ma. Celeste Abad mula sa </span><i><span style="font-weight: 400;">Philippine Genome Center</span></i><span style="font-weight: 400;">; Dr. Juan Carlos Gonzalez ng UP Los Baños; at Dr. Jayson Ibañez ng PEF.</span></p><p> </p><p><span style="font-weight: 400;">Layunin ng pangkat na makabuo ng isang </span><i><span style="font-weight: 400;">draft genome </span></i><span style="font-weight: 400;">ng Haring Ibon na magsisilbing gabay sa mga gawaing pang-konserbasyon. Sa tulong ng PEF, isinailalim nila sa </span><i><span style="font-weight: 400;">DNA sequencing </span></i><span style="font-weight: 400;">ang mga agilang inaalagaan sa Davao City. &#8220;Ang </span><i><span style="font-weight: 400;">genome </span></i><span style="font-weight: 400;">ay ang kumpletong hanay ng mga </span><i><span style="font-weight: 400;">gene </span></i><span style="font-weight: 400;">ng isang buhay na organismo,&#8221; paliwanag ng mga siyentipiko. &#8220;Mula sa mga nakuhang </span><i><span style="font-weight: 400;">DNA sequences</span></i><span style="font-weight: 400;">, nagawa naming buuin ang isang kinatawang </span><i><span style="font-weight: 400;">genome </span></i><span style="font-weight: 400;">(</span><i><span style="font-weight: 400;">representative genome</span></i><span style="font-weight: 400;">) para sa </span><i><span style="font-weight: 400;">species </span></i><span style="font-weight: 400;">na ito.&#8221; </span></p><p> </p><p><span style="font-weight: 400;">Sa kanilang pag-aaral, iniulat ang isang bagong natuklasan: napakababa ng </span><i><span style="font-weight: 400;">genetic diversity </span></i><span style="font-weight: 400;">ng Haring Ibon. Ibig sabihin, mataas ang pagkakahawig ng mga agila sa isa&#8217;t isa at halos magkakapareho ang kanilang mga </span><i><span style="font-weight: 400;">gene</span></i><span style="font-weight: 400;">. &#8220;Ang panganib dito, kapag kulang sa pagkakaiba-iba (</span><i><span style="font-weight: 400;">variation</span></i><span style="font-weight: 400;">) ang kanilang katangian, mahihirapan ang mga agila na umangkop sa mga pagbabago. Halimbawa, kung may umusbong na bagong sakit o biglang magbago ang kapaligiran, pare-pareho ang magiging reaksyon at kakayahan ng marami sa kanila—at kung mahina ang kanilang depensa, posibleng maubos ang buong populasyon,&#8221; babala ng pangkat. </span></p><p> </p><p><span style="font-weight: 400;">Binigyang-diin din ng mga mananaliksik na pinatataas nito ang panganib ng </span><i><span style="font-weight: 400;">inbreeding</span></i><span style="font-weight: 400;">. Nangyayari ito kapag napipilitang magkapareha ang mga agilang magkakamag-anak dahil sa liit ng kanilang populasyon at dahil watak-watak na ang kanilang tirahan. Sa mga ganitong sitwasyon, mas malaki ang tsansa na maipasa sa mga supling ang mga mapaminsalang katangian o depekto sa </span><i><span style="font-weight: 400;">gene</span></i><span style="font-weight: 400;">. Sa paglipas ng panahon, maaari itong magbunga ng mas mababang kakayahang magpakarami (</span><i><span style="font-weight: 400;">reduced fertility</span></i><span style="font-weight: 400;">), mahinang </span><i><span style="font-weight: 400;">immune system</span></i><span style="font-weight: 400;">, at mga depekto sa pisikal na anyo na lalong nagpapahirap sa kanilang kaligtasan. &#8220;Sa madaling salita, ang mababang </span><i><span style="font-weight: 400;">genetic diversity </span></i><span style="font-weight: 400;">ay nagiging dahilan upang maging marupok ang Haring Ibon at mas madaling maglaho kapag may mga pagsubok na dumarating,&#8221; dagdag pa nila. </span></p><p> </p><p><span style="font-weight: 400;">Ipinapakita rin sa mga datos na bago pa man nagkaroon ng malawakang pagkasira ng mga kagubatan (</span><i><span style="font-weight: 400;">deforestation</span></i><span style="font-weight: 400;">), pababa na talaga ang populasyon ng mga Haring Ibon. Ang isang posibleng dahilan ay ang mga pangmatagalang pagbabago sa kalikasan—tulad ng pagkawala ng mga magkakakonektang tirahan nang tumaas ang antas ng dagat libu-libong taon na ang nakalipas, na nagdulot ng pagkakawatak-watak ng mga dating magkakadikit na kalupaan sa Mindanao. Ang pangyayaring ito ay naging sanhi ng pagkakabukod-bukod ng mga grupo ng </span><span style="font-weight: 400;">agila at nakasira sa katatagan ng kanilang populasyon. Maaari ring ang mga unang aktibidad ng mga tao sa Pilipinas, gaya ng pangangaso o pakikipag-agawan sa mga hayop na kinakain ng agila, ay lalong nagpahirap sa kanilang sitwasyon. </span></p><p> </p><p><span style="font-weight: 400;">Nilinaw naman ng mga siyentipiko na ang mga ito ay mga hinuha (</span><i><span style="font-weight: 400;">hypotheses</span></i><span style="font-weight: 400;">) pa lamang at hindi pa ganap na tiyak. Gayunpaman, nakatutulong ito upang ipaliwanag kung bakit tila mas naunang dumanas ng pagbaba sa populasyon ang mga agila bago pa man ang </span><i><span style="font-weight: 400;">deforestation</span></i><span style="font-weight: 400;">, na madalas na itinuturing na pangunahing banta sa kanila ngayon. </span></p><p> </p><p><span style="font-weight: 400;">&#8220;Sa pamamagitan ng paggamit ng pamamaraang nakabatay sa </span><i><span style="font-weight: 400;">genomics </span></i><span style="font-weight: 400;">at gabay ng </span><i><span style="font-weight: 400;">genetics</span></i><span style="font-weight: 400;">, ang aming pag-aaral ay nagbibigay ng gabay o </span><i><span style="font-weight: 400;">blueprint </span></i><span style="font-weight: 400;">upang maprotektahan ang iba pang mga nanganganib na </span><i><span style="font-weight: 400;">species </span></i><span style="font-weight: 400;">sa buong kapuluan. Ipinapakita rin nito kung paano magagamit ang makabagong pagsusuri sa DNA at </span><i><span style="font-weight: 400;">bioinformatics </span></i><span style="font-weight: 400;">upang mapatibay ang pamamahala sa </span><i><span style="font-weight: 400;">biodiversity</span></i><span style="font-weight: 400;">,&#8221; saad ng pangkat. </span></p><p> </p><p><span style="font-weight: 400;">Ang pag-aaral na pinamagatang, </span><i><span style="font-weight: 400;">&#8220;Genomic analysis reveals recent population decline and exceptionally low genome-wide heterozygosity of the critically endangered Philippine eagle, Pithecophaga jefferyi (Aves: Accipitridae),&#8221; </span></i><span style="font-weight: 400;">ay inilathala sa </span><i><span style="font-weight: 400;">BMC Genomics</span></i><span style="font-weight: 400;">, isang </span><i><span style="font-weight: 400;">open access </span></i><span style="font-weight: 400;">at </span><i><span style="font-weight: 400;">peer-reviewed </span></i><span style="font-weight: 400;">na journal na naglalathala ng mga artikulo tungkol sa lahat ng aspeto ng </span><i><span style="font-weight: 400;">genetics</span></i><span style="font-weight: 400;">, </span><i><span style="font-weight: 400;">genomics</span></i><span style="font-weight: 400;">, at </span><i><span style="font-weight: 400;">proteomics</span></i><span style="font-weight: 400;">.</span></p><p> </p><p><b>Sanggunian:</b></p><p><span style="font-weight: 400;">Perdon, D.

Celeste Abad of the Philippine Genome Center; Dr. Juan Carlos Gonzalez of UP Los Baños; and Dr. Jayson Ibañez of the Philippine Eagle Foundation (PEF) to study the DNA of 35 Philippine eagles under the care of PEF.</span></p><p> </p><p><span style="font-weight: 400;">The team aimed to create a draft genome of the Philippine eagle to help guide conservation efforts. Through collaboration with PEF, they sequenced the DNA of Philippine eagles under their care in Davao City. “A genome is a living organism’s complete set of genes,” the scientists explained. “From the extracted DNA sequences, we were able to assemble a representative genome for the species.”</span></p><p> </p><p><span style="font-weight: 400;">Their study reported a novel finding that the Philippine eagle has exceptionally low genetic diversity, meaning individuals are highly similar to one another and share nearly the same set of genes. “The danger is that when there’s little variation, the species struggles to adapt to changes. For example, if a new disease appears or the environment shifts, most eagles would react the same way and have the same capacity to adapt—and if they’re vulnerable, the whole population could be wiped out,” they said.</span></p><p> </p><p><span style="font-weight: 400;">The team noted that this also increases the risks associated with inbreeding, which occurs when eagles are forced to mate with closely related individuals due to small population size and fragmented habitats. In such cases, harmful traits or genetic weaknesses are more likely to appear in offspring. Over time, this can result in reduced fertility, weakened immune systems, and physical abnormalities that make survival more difficult. “In short, low genetic diversity makes the Philippine Eagle fragile and more likely to face extinction when challenges arise,” they added.</span></p><p> </p><p><span style="font-weight: 400;">Their findings also suggest that the Philippine eagle population was already declining before widespread deforestation. One possible explanation is that long-term ecological changes—such as the loss of connected habitats when sea levels rose thousands of years ago, fragmenting what were once larger continuous landmasses in Mindanao—may have disrupted population stability and isolated eagle groups. It is also possible that early human activities in the Philippines, such as hunting or competition for prey, placed additional pressure on the population. </span></p><p> </p><p><span style="font-weight: 400;">The scientists clarified that these are hypotheses rather than certainties, but they help explain why the Philippine eagle decline appears to have started earlier than deforestation, which is often considered the main threat.</span></p><p> </p><p><span style="font-weight: 400;">“By applying a genomics-driven, genetically informed approach, our study offers a blueprint for safeguarding other threatened species across the archipelago, and demonstrates how modern DNA analysis and bioinformatics can be leveraged to strengthen biodiversity management,” they said.</span></p><p> </p><p><span style="font-weight: 400;">The study, “Genomic analysis reveals recent population decline and exceptionally low genome-wide heterozygosity of the critically endangered Philippine eagle, </span><i><span style="font-weight: 400;">Pithecophaga jefferyi </span></i><span style="font-weight: 400;">(Aves: Accipitridae),” is published in </span><i><span style="font-weight: 400;">BMC Genomics</span></i><span style="font-weight: 400;">, an open access, peer-reviewed journal that considers articles on all aspects of genetics, genomics, and proteomics.</span></p><p> </p><p><b>References:</b></p><p><span style="font-weight: 400;">Perdon, D.

Sa pamamagitan ng kwento ni Dr. Gay Perez, umaasa siyang makahikayat ito ng mga batang Pilipino na abutin ang kanilang mga pangarap at maging bahagi ng susunod na henerasyon ng mga siyentistang magdadala sa agham at pananaliksik ng Pilipinas sa mas mataas na antas. “Nais ko ng ipakita sa mga kabataan ang isang tunay halimbawa ng Pilipina na nakakamit ng malaking tagumpay,” aniya.</span></p><p> </p>					</div>

				<p><span style="font-weight: 400;">Ibinahagi naman ni Dr. Perez ang kanyang saloobin sa pagkakaroon ng isang aklat pambata na tampok ang kanyang buhay. “Kung may isang salitang makakapaglarawan sa karanasang ito, iyon ay nakakapagpapakumbaba. Nagulat ako na may ganitong uri ng proyekto. Nang mabasa ko ang aklat, ay yun din ang unang pagkakataong nakita ko ang sarili kong kwento. Kakaiba ang pakiramdam dahil kapag ako ay nagkwekwento ng aking buhay, piling bahagi lamang ang naibabahagi ko. Ngunit sa kwentong sinulat ni Eugene- mula sa aking kabataan sa Naga, hanggang sa NASA at sa PhilSA, ay nagbigay ito sa akin ng mas malalim na pagpapahalaga sa aking pinagdaanan. Nakita ko ang aking kwento mula sa ibang pananaw,” aniya.</span></p><p> </p><p><span style="font-weight: 400;">Ibinahagi rin ni Dr. Perez na tulad ng maraming kabataan, itinuring niya noon ang sarili bilang isang ordinaryong tao. Hindi niya pinangarap maging siyentista sapagkat wala naman siyang kilalang siyentista noong siya ay bata pa. “Ang mensaheng nais kong ipaabot sa mga batang babasa ng aking kwento, ay kaya rin nilang makamit ito—at higit pa. Dumating ang mga oportunidad sa aking buhay, at naging handa akong yakapin ang mga ito at harapin ang mga hamon. Dahil doon, narating ko kung nasaan ako ngayon,” dagdag niya.</span></p><p> </p><p><span style="font-weight: 400;">Binigyang-diin din ni Dr. Perez na ang maagang pagkakaroon ng mga role models ay maaaring magbukas ng mas maraming oportunidad para sa mga batang babae na pumasok sa larangan ng Agham, Teknolohiya, Inhinyeriya, at Matematika (STEM). Habang lumalaki, ang mga babaeng siyentistang nakikita niya ay kadalasan lamang sa mga pelikula, at madalas pang inilalarawan bilang mga “baliw na siyentista” na magulo ang buhok. “Noong bata pa ako, sana ay mas marami akong naging role models—napakahalaga niyon. Nagpapasalamat ako na nang dumating ang panahon ng pagpapasya tungkol sa aking karera, ay nabigyan ako ng pagkakataong makatrabaho ang mga taong maaari kong tularan, at sila ang naging inspirasyon ko upang tahakin ang agham,” paggunita niya.</span></p><p> </p><p><span style="font-weight: 400;">Ayon naman kay Dr. Giovanni Tapang, dating Dekano ng UPD-CS, kaibigan at dating kasamahan  ni Dr. Perez sa National Institute of Physics (NIP), ipinakikita ng Isang Puwang sa Kalawakan kung gaano kahalaga ang agham at teknolohiya sa paghubog ng kinabukasan ng bansa. Binigyang-diin niya ang kahalagahan ng ambag ni Dr. Perez sa larangan ng agham pangkalawakan. Dagdag pa niya, ang aklat ay hindi lamang pagdiriwang ng mga tagumpay ni Dr. Perez kundi pagkilala rin na may lugar ang kababaihan sa larangan ng space science at STEM. “May kakayahan tayong angkinin ang maliit na puwang na iyon, palawakin ito, at ilantad para sa kapakinabangan ng Pilipinas,” pagtatapos ni Dr. Tapang.</span></p><p> </p><p><span style="font-weight: 400;">Nabuo ang serye ng mga aklat pambatang Sulong Agham sa pamamagitan ng pagtutulungan ng Kolehiyo ng Agham at Kolehiyo ng Arte at Literatura ng UP Diliman, at ng non-profit na organisasyong Supling Sining, Inc.</span></p><p> </p><p><span style="font-weight: 400;">Kabilang din sa iba pang aklat sa seryeng ito ang Ang Doktor ng Dagat, na tampok ang marine scientist na si Deo Florence Onda na isinulat ni Prof. Rosario Torres-Yu; at Ang Natatanging Ngaratngat, na tampok ang biologist na si Leonard Co na isinulat naman ni Prof. Mon Sy.</span></p>					</div>

The event was graced by Dr. Gay Jane Perez, author Dr. Eugene Evasco, and illustrator Henrick Dulin. “Isang Puwang sa Kalawakan” explores Dr. Perez’s life and work as the leader of the team behind Diwata-1, the first Philippine microsatellite and the first satellite designed and built by Filipinos.</span></p><p> </p><p><span style="font-weight: 400;">Dr. Evasco, a Palanca Hall of Fame awardee, described the story as being about a “makabayang siyentista,” whose goal is not only personal advancement but also the service of the nation. Through Dr. Perez’s story, he hopes to inspire Filipino children to pursue their dreams, sparking the next generation of scientists who will carry Filipino science and research beyond the country. “I wanted to show young people a real Filipino woman reaching great heights,” he said.</span></p><p> </p>					</div>

				<p><span style="font-weight: 400;">Meanwhile, Dr. Perez described the experience of having a children’s book featuring her life and work as humbling. “If there’s one adjective, that’s it. I was surprised that this kind of work exists. When I saw the narrative, it was also the first time I saw my own story. It felt strange because when I tell my story, I only tell parts of it—but what Eugene wrote, from my childhood in Naga to NASA to PhilSA, made me appreciate it deeply. I saw it from a different perspective,” she shared.</span></p><p> </p><p><span style="font-weight: 400;">Dr. Perez mentioned that, like many children, she considered herself ordinary back then. She did not dream of becoming a scientist because she didn’t know one. “The message I want to share with young readers is that they can also achieve this—and even more. Opportunities came my way, and I was ready to embrace them and take on the challenges. That led me to where I am now,” she added.</span></p><p> </p><p><span style="font-weight: 400;">Dr. Perez emphasized that early exposure to role models can open more opportunities for young girls to pursue careers in science, technology, engineering, and mathematics (STEM). Growing up, the only female scientists she saw were in movies, often depicted as “mad scientists” with messy hair. “When I was young, I wished I had more role models—it’s very important. I’m grateful that when I was making decisions about my career, I had the chance to work with people I could look up to, and that inspired me to pursue science,” she recalled.</span></p><p> </p><p><span style="font-weight: 400;">“[Isang Puwang sa Kalawakan] demonstrates how science and technology play an important role in building our country’s future,” Former UPD-CS Dean and Dr. Perez’s friend Dr. Giovanni Tapang said, underscoring the importance of her work in space science. He added that “Isang Puwang sa Kalawakan” is not merely a celebration of Dr. Perez’s achievements, but also a recognition that there is space for women in the STEM field. “We have the capacity to claim that small space, expand it, and bring it out into the open for the benefit of the Philippines,” Dr. Tapang concluded.</span></p><p> </p><p><span style="font-weight: 400;">The Sulong Agham children’s book series was born out of a collaboration between the UPD-CS, the non-profit organization Supling Sining, Inc. (SSI), and the UPD College of Arts and Letters Departamento ng Filipino at Panitikang Pilipino (UPD-CAL DFPP).</span></p><p><span style="font-weight: 400;">Other books in this book series include “Ang Doktor ng Dagat,” featuring marine scientist Dr. Deo Florence Onda and written by Dr. Rosario Torres-Yu, and “Ang Natatanging Ngaratngat,” featuring Filipino biologist Leonard Co and written by Mon Sy.</span></p>					</div>

Gamit ang </span><i><span style="font-weight: 400;">viral metagenomics</span></i><span style="font-weight: 400;">—isang pamamaraan na tumutukoy sa lahat ng virus sa isang sampol—sinuri nila ang </span><i><span style="font-weight: 400;">virome </span></i><span style="font-weight: 400;">(kabuuan ng mga virus) sa loob ng mga lamok. </span></p><p> </p><p><span style="font-weight: 400;">Natuklasan sa kanilang pananaliksik na ang mga lamok ay nagtataglay ng mga virus mula sa 12 magkakaibang </span><i><span style="font-weight: 400;">taxon group</span></i><span style="font-weight: 400;">. Karamihan sa mga ito ay mga </span><i><span style="font-weight: 400;">insect-specific virus </span></i><span style="font-weight: 400;">(ISV).

Ang Bagong Silang ang </span><i><span style="font-weight: 400;">upstream </span></i><span style="font-weight: 400;">(bundok) na site, na matatagpuan 305–331 metro sa itaas ng antas ng dagat (</span><i><span style="font-weight: 400;">asl</span></i><span style="font-weight: 400;">), at may maburol na tanawin (</span><i><span style="font-weight: 400;">rolling landscape</span></i><span style="font-weight: 400;">). Ang Lalakay naman ang </span><i><span style="font-weight: 400;">midstream </span></i><span style="font-weight: 400;">na site—na nailalarawan sa pagkakaroon ng maburol hanggang sa medyo hindi pantay na lupain. Ang Bayog, na siyang tabing-lawa na site (</span><i><span style="font-weight: 400;">lakeshore site</span></i><span style="font-weight: 400;">), ay may patag na lupain. </span></p><p> </p><p><span style="font-weight: 400;">&#8220;Batay sa mga </span><i><span style="font-weight: 400;">land cover map</span></i><span style="font-weight: 400;">, napanatili ng Bagong Silang ang </span><i><span style="font-weight: 400;">forest cover </span></i><span style="font-weight: 400;">nito sa nakalipas na apat na dekada hanggang sa petsa ng pag-aaral. Sa kaparehong panahon, kapwa sumailalim ang Lalakay at Bayog sa konbersiyon mula sa pagiging agrikultural patungo sa mga </span><i><span style="font-weight: 400;">built-up area </span></i><span style="font-weight: 400;">(mga may estruktura at pamayanan),&#8221; pagbabahagi nila. </span></p><p> </p><p><span style="font-weight: 400;">Ipinakita rito sa pag-aaral na mas maraming uri ng virus ang natagpuan sa mga lugar na nabago na ng aktibidad ng tao—tulad ng mga urbanisado o nakalbong lupa, gaya ng mga Barangay Lalakay at Bayog—kumpara sa kagubatan ng Bagong Silang. &#8220;Ang mga lamok na ito ay kadalasang matatag sa mga pagbabago sa kapaligiran (</span><i><span style="font-weight: 400;">disturbance-resilient</span></i><span style="font-weight: 400;">), at mas mabisang host para sa iba&#8217;t ibang uri o </span><i><span style="font-weight: 400;">strain </span></i><span style="font-weight: 400;">ng virus,&#8221; dagdag pa ng mga </span><i><span style="font-weight: 400;">molecular biologist</span></i><span style="font-weight: 400;">. Kapansin-pansin na hindi nakita ng pangkat ang mga virus ng dengue, Zika, o chikungunya sa mga sampol. Gayunpaman, natuklasan na ang mga lamok mula sa dalawang barangay ay nagtataglay ng </span><i><span style="font-weight: 400;">Cell Fusing Agent Virus </span></i><span style="font-weight: 400;">(CFAV). Ang CFAV ay pinaniniwalaang pumipigil sa pagdami ng mga virus ng Dengue at Zika.</span></p><p> </p><p><span style="font-weight: 400;">&#8220;Ang potensyal na panganib ng mga umuusbong at posibleng hindi pa kilalang banta ng </span><i><span style="font-weight: 400;">arbovirus </span></i><span style="font-weight: 400;">ay nangangailangan ng mas pinalakas na mga programa sa pagsubaybay (</span><i><span style="font-weight: 400;">surveillance</span></i><span style="font-weight: 400;">) at </span><i><span style="font-weight: 400;">advanced </span></i><span style="font-weight: 400;">na pananaliksik sa mga </span><i><span style="font-weight: 400;">arboviral disease</span></i><span style="font-weight: 400;">—mga sakit na naililipat ng mga insekto tulad ng lamok,&#8221; ayon sa kanila.

				<p><span style="font-weight: 400;">Mosquitoes such as </span><i><span style="font-weight: 400;">Aedes aegypti</span></i><span style="font-weight: 400;"> and </span><i><span style="font-weight: 400;">Aedes albopictus</span></i><span style="font-weight: 400;">, 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.</span></p><p> </p><p><span style="font-weight: 400;">Irish Coleen Asin, John Michael Egana, and Dr. Ma. Anita Bautista of the University of the Philippines – Diliman College of Science’s National Institute of Molecular Biology and Biotechnology (UPD-CS NIMBB), together with Dr. Richard Paul of Institut Pasteur, Université Paris Cité, collected mosquitoes from three areas in Los Baños, Laguna that differ in topography and land use. Using viral metagenomics—a method that identifies all viruses in a sample—they analyzed the virome inside the mosquitoes.</span></p><p> </p><p><span style="font-weight: 400;">Their research revealed that the mosquitoes carried viruses from 12 different taxon groups. Most of these were insect-specific viruses (ISVs), which infect mosquitoes but not humans. Both </span><i><span style="font-weight: 400;">A. aegypti</span></i><span style="font-weight: 400;"> and </span><i><span style="font-weight: 400;">A. albopictus</span></i><span style="font-weight: 400;"> also shared the majority of the identified viruses.</span></p><p><span style="font-weight: 400;">The molecular biologists collected mosquito samples from three barangays in Los Baños, Laguna: Bagong Silang, Lalakay, and Bayog. Bagong Silang is the upstream (mountain) site, located 305–331 meters above sea level (asl), with a rolling landscape. Lalakay is the midstream site—characterized by rolling to slightly uneven terrain. Bayog, the lakeshore site, has a flat landscape.</span></p><p><span style="font-weight: 400;">“Based on the land cover maps, Bagong Silang retained its forest cover in the last 4 decades as of the study date. At the same time, both Lalakay and Bayog underwent conversion from agricultural to built-up areas during that period,” they shared.</span></p><p> </p><p><span style="font-weight: 400;">The study also showed that more types of viruses were found in areas altered by human activity—such as urban or cleared land, like Barangays Lalakay and Bayog—compared to the forested area of Bagong Silang. “These mosquitoes are usually disturbance-resilient and are more competent hosts for several viral isolates or strains,” the molecular biologists added. Notably, the team did not detect dengue, Zika, or chikungunya viruses in the samples. Interestingly, mosquitoes from two barangays were found to harbor the Cell Fusing Agent Virus (CFAV). CFAV has been thought to inhibit the proliferation of Dengue and Zika viruses.</span></p><p> </p><p><span style="font-weight: 400;">“The potential risk of emerging and possibly unknown arboviral threats calls for strengthened surveillance programs and advanced research on arboviral diseases—those transmitted by insects like mosquitoes,” they said, emphasizing that arbovirus surveillance programs are vital to public health, as they monitor the activity of both endemic and emerging viruses in real time to help manage outbreaks. Such monitoring can be enhanced through next-generation sequencing techniques, including virome sequencing.</span></p><p> </p><p><span style="font-weight: 400;">The molecular biologists also noted that mosquitoes may serve as important biological targets for zoonotic and arboviral disease surveillance programs. “Mosquitoes act like biological syringes, feeding on multiple kinds of hosts,” the team pointed out. “Because of this, they can provide valuable insights into viral diversity across space, time, and species.”</span></p><p> </p><p><span style="font-weight: 400;">Their study, “Virome sequencing and analysis of </span><i><span style="font-weight: 400;">Aedes aegypti</span></i><span style="font-weight: 400;"> and </span><i><span style="font-weight: 400;">Aedes albopictus</span></i><span style="font-weight: 400;"> from ecologically different sites in the Philippines,” was published in </span><i><span style="font-weight: 400;">Parasites &amp; Vectors</span></i><span style="font-weight: 400;">. This international journal focuses on all aspects of the biology of parasites, parasitic diseases, intermediate hosts, vectors, and vector-borne pathogens.

				<p><span style="font-weight: 400;">Binuo ni Dr. Bryan Hernandez ng University of the Philippines – Diliman College of Science Institute of Mathematics (UPD-CS IM), kasama sina Patrick Vincent Lubenia at Dr. Eduardo Mendoza ng Center for Natural Science and Environmental Research, De La Salle University, ang Common Species Embedded Networks (CSEN) analysis.</span></p><p> </p><p><span style="font-weight: 400;">Pinaghahambing ng CSEN analysis ang dalawang reaction networks na pareho o magkatulad ang sistema sa pamamagitan ng pagtuon sa kanilang mga karaniwang species, tulad ng mga protein o kemikal, upang matukoy ang mga pagkakatulad at pagkakaiba.</span></p><p> </p><p><span style="font-weight: 400;">&#8220;Gumagana ang method sa pamamagitan ng unang paghihiwalay sa mga network na &#8216;naka-embed&#8217; sa loob ng mga modelo na kinasasangkutan lamang ng mga karaniwang species. Para sa mga reaksyon na hindi magkapareho, sinusuri ng method ang mga &#8216;transformation&#8217;—mga mathematical link na maaaring magpaliwanag kung paano maaaring magdulot ng equivalence ang isang set ng reaksyon sa pagitan ng mga system na may underlying embedded networks,&#8221; paliwanag ni Dr. Hernandez.</span></p><p> </p><p><span style="font-weight: 400;">Inihambing ng kanilang grupo ang mga kasalukuyang reaction network na nauugnay sa mga Wnt signaling model na kanilang natukoy, kasama ang mga iyon nina Lee, Schmitz, MacLean, at Feinberg. Sa pamamagitan ng CSEN analysis, nalaman ng mga mathematician na ang ilang umiiral na mga modelo ay lubos na magkatulad dahil ang kanilang mga embedded network ay konektado sa isa’t isa sa pamamagitan ng mga partikular na transformation. Sa kabilang banda, maaari ring mabunyag ng analysis kung walang maihahambing na relasyon ang umiiral sa mga modelo dahil sa kawalan ng naturang transformation.</span></p><p> </p><p><span style="font-weight: 400;">Ibinahagi ni Dr. Hernandez ang inspirasyon ng grupo sa likod ng paglikha ng CSEN analysis. &#8220;Sa larangan ng systems biology, madalas na nagmumungkahi ang iba&#8217;t ibang mananaliksik ng iba&#8217;t ibang mga reaction network upang ilarawan ang iisang biological process. Sa kasaysayan, mahirap ding paghambingin ang mga modelong ito dahil madalas silang ituring bilang ganap na magkahiwalay na mga entity, na gumagamit ng iba&#8217;t ibang hanay ng mga variable at reaction.&#8221;</span></p><p> </p><p><span style="font-weight: 400;">Tinutugunan ng CSEN analysis ang kahirapang ito sa pamamagitan ng pagbibigay-diin sa dalawang pangunahing haligi: network embedding, kung saan sinasala ang mga complex network para ituon lang sa mga species na makikita sa pagitan ng mga model; at mga structural comparison, kung saan sinusuri ang mga embedded network upang matukoy kung ang isang model ay isang mas kumplikadong bersyon ng isa pa o kung ang mga ito ay &#8220;halos katumbas&#8221; sa pamamagitan ng mga mathematical transformation.</span></p><p> </p><p><span style="font-weight: 400;">&#8220;Madalas napaghihiwalay ang mga modelo ng mga traditional approach batay sa mga specific property, tulad ng kung mayroon silang isang long-term state (mono-stationarity) o multiple long term states (multi-stationarity). Iba ang CSEN dahil tinitingnan nito ang underlying structure at dynamic equivalence,&#8221; dagdag ni Dr. Hernandez.</span></p><p> </p><p><span style="font-weight: 400;">Naging insightful ang CSEN analysis sa Wnt signaling, na nagpapakitang ang ilang models—na noong una ay itinuturing na naiiba dahil sa kanilang mga stability property—ay talagang halos magkapareho sa istruktura.</span></p><p> </p><p><span style="font-weight: 400;">Ayon kay Dr. Hernandez, isang pangkalahatang mathematical tool ang CSEN analysis na maaaring ilapat sa mga modelo para sa mga system maliban pa sa Wnt signaling. &#8220;Habang ipinakita namin ang paggamit nito sa Wnt signaling, maaari itong ilapat sa anumang system na kinakatawan ng mga reaction network. Kabilang dito ang iba pang biological pathway, gaya ng insulin signaling o metabolism, pati na rin ang mga potential non-biological network gaya ng mga chemical engineering process o ecological model.&#8221;</span></p><p> </p><p><span style="font-weight: 400;">Maaaring maging mahalaga ang CSEN analysis sa pagpino ng mga model sa biological at chemical systems sa pamamagitan ng pagtukoy kung aling mga bahagi ng isang modelo—o kung aling mga modelo—ang natatangi at alin ang redundant. Maaaring bigyan ng pansin ng analysis na ito ang mga robust target: kung maraming mga modelo, sa kabila ng kanilang mga pagkakaiba, ay nagkakaisa sa iisang interaction na nagdudulot ng isang uri ng sakit, ang interaction na ito ay nagiging isang mas maaasahan at robust na therapeutic target.</span></p><p> </p><p><span style="font-weight: 400;">Ang kanilang pagsasaliksik, “Embedding-based comparison of reaction networks of Wnt signaling,&#8221; ay kasama sa </span><i><span style="font-weight: 400;">MATCH Communications in Mathematical and in Computer Chemistry</span></i><span style="font-weight: 400;">, isang open-access na journal na naglalathala ng mga orihinal na pananaliksik pati na rin ang mga review ukol sa chemically important mathematical results at non-routine na paggamit ng mga mathematical technique sa mga chemical problem.</span></p><p> </p><p><b>References:</b></p><p><span style="font-weight: 400;">Hernandez, B.

				<p><span style="font-weight: 400;">Dr. Bryan Hernandez of the University of the Philippines – Diliman College of Science’s Institute of Mathematics (UPD-CS IM), along with Patrick Vincent Lubenia and Dr. Eduardo Mendoza of the Center for Natural Science and Environmental Research, De La Salle University, developed the Common Species Embedded Networks (CSEN) analysis.</span></p><p> </p><p><span style="font-weight: 400;">The CSEN analysis compares two reaction networks of the same or similar systems by focusing on their common species, such as proteins or chemicals, to identify similarities and differences.</span></p><p> </p><p><span style="font-weight: 400;">“The method works by first isolating the networks ‘embedded’ within the models that involve only the common species. For the reactions that are not identical, the method checks for ‘transformations’—mathematical links that can explain how one reaction set might induce equivalence between the systems with the underlying embedded networks,” Dr. Hernandez explained.</span></p><p> </p><p><span style="font-weight: 400;">Their group compared existing reaction networks associated with Wnt signaling models they had identified, including those by Lee, Schmitz, MacLean, and Feinberg. Through the CSEN analysis, the mathematicians found that some existing models are strongly similar because their embedded networks are connected through specific transformations. Conversely, the analysis can also reveal when no comparable relationship exists due to the absence of such transformations.</span></p><p> </p><p><span style="font-weight: 400;">Dr. Hernandez shared the team’s inspiration behind creating the CSEN analysis. “In the field of systems biology, different researchers often propose different reaction networks to describe the same biological process. Historically, it has also been difficult to compare these models because they are often treated as entirely separate entities, utilizing different sets of variables and reactions.”</span></p><p> </p><p><span style="font-weight: 400;">The CSEN analysis addresses this difficulty by emphasizing two key pillars: network embedding, which narrows complex networks to focus only on the species shared between models; and structural comparisons, in which the embedded networks are analyzed to determine whether one model is a more complex version of another or if they are “proximately equivalent” through mathematical transformations.</span></p><p><span style="font-weight: 400;">“Traditional approaches often discriminate between models based on specific properties, such as whether they have one long-term state (mono-stationarity) or the capacity for multiple long-term</span> <span style="font-weight: 400;">states (multi-stationarity). CSEN is different because it looks at the underlying structure and dynamical equivalence,” Dr. Hernandez added.</span></p><p> </p><p><span style="font-weight: 400;">The CSEN analysis was particularly insightful for Wnt signaling, revealing that certain models—previously thought to differ fundamentally due to their stability properties—are actually structurally very similar.</span></p><p> </p><p><span style="font-weight: 400;">According to Dr. Hernandez, the CSEN analysis is a general mathematical tool that can be applied to models in systems beyond Wnt signaling. “While we demonstrated its use with Wnt signaling, it can be applied to any system represented by reaction networks. This includes other biological pathways, such as insulin signaling or metabolism, as well as potentially non-biological networks such as chemical engineering processes or ecological models.”</span></p><p> </p><p><span style="font-weight: 400;">The CSEN analysis can be vital in refining models in biological and chemical systems by identifying which parts of a model—or which models—are unique and which are redundant. This method can highlight robust targets: if many models, despite their differences, agree that a specific interaction drives a disease, that interaction becomes a more reliable and robust therapeutic target.</span></p><p> </p><p><span style="font-weight: 400;">Their research, “Embedding-based comparison of reaction networks of Wnt signaling,” is included in </span><i><span style="font-weight: 400;">MATCH Communications in Mathematical and in Computer Chemistry</span></i><span style="font-weight: 400;">, an open-access journal that publishes papers of original research as well as reviews on chemically important mathematical results and non-routine applications of mathematical techniques to chemical problems.</span></p><p> </p><p><b>References:</b></p><p><span style="font-weight: 400;">Hernandez, B.

				<p><span style="font-weight: 400;">As antimicrobial resistance (AMR) continues to make traditional antibiotics less effective worldwide, the search for new antibacterial treatments has become increasingly urgent. One promising solution is antimicrobial peptides (AMPs), small molecules that can kill bacteria. To help accelerate their discovery, researchers at the University of the Philippines Diliman – College of Science (UPD-CS) have developed an AI tool designed to accelerate the discovery of new antibacterial peptides.</span></p><p> </p><p><span style="font-weight: 400;">Remmer Salas, Dr. Portia Mahal Sabido, and Dr. Ricky Nellas of the UPD-CS Institute of Chemistry (IC) developed ISCAPE (Interpretable Support Vector Classifier of Antibacterial Activity of Peptides against </span><i><span style="font-weight: 400;">Escherichia coli</span></i><span style="font-weight: 400;">). It is an AI-powered tool that helps experimentalists predict whether a peptide can kill or inhibit the growth of </span><i><span style="font-weight: 400;">E. coli</span></i><span style="font-weight: 400;">. The system requires only a Simplified Molecular-Input Line-Entry System (SMILES) string as input, making it simple for researchers to evaluate candidate molecules.</span></p><p> </p><p><span style="font-weight: 400;">“Traditionally, discovering antibacterial peptides means synthesizing many candidates and testing them one by one. This process is time-consuming,” said Salas. “We used AI to learn from existing data and identify patterns that distinguish active peptides from inactive ones.”</span></p><p> </p><p><span style="font-weight: 400;">Unlike many AI tools, ISCAPE also shows which molecular features make a peptide effective. He noted that this helps researchers save time and resources. It reduces trial-and-error experiments and allows them to design better peptides more efficiently.</span></p><p> </p><p><span style="font-weight: 400;">“ISCAPE helps address antimicrobial resistance by accelerating early-stage screening through data-driven peptide design,” Salas further explained. “It doesn’t replace laboratory experiments, but it makes discovery more efficient and helps researchers focus on the most promising candidates.”</span></p><p> </p><p><span style="font-weight: 400;">The AI-powered model can be adapted to predict activity against bacteria other than </span><i><span style="font-weight: 400;">E. coli</span></i><span style="font-weight: 400;">. However, it would need to be retrained using high-quality datasets specific to the bacterial strains of interest. The ISCAPE approach could also be applied to predict the activity of other bioactive peptides. </span></p><p> </p><p><span style="font-weight: 400;">“Applying ISCAPE to other biological targets requires well-curated datasets with experimentally validated activity,” Salas added. “The model must then be retrained using the molecular features we identified as optimal for peptides.”</span></p><p> </p><p><span style="font-weight: 400;">The team hopes the tool will help researchers design better antibacterial peptides more efficiently and contribute to the global fight against AMR.</span></p><p> </p><p><span style="font-weight: 400;">ISCAPE is publicly available for other scientists. The web server can be accessed through </span><a href="https://huggingface.co/spaces/rlsalas/iscape"><span style="font-weight: 400;">Hugging Face Spaces</span></a><span style="font-weight: 400;">. The training data and code for large-scale prediction are available on </span><a href="https://github.com/mersalas/ISCAPE"><span style="font-weight: 400;">GitHub</span></a><span style="font-weight: 400;">.</span></p><p> </p><p><span style="font-weight: 400;">The chemists’ research paper, titled “Interpretable support vector classifier for reliable prediction of antibacterial activity of modified peptides against </span><i><span style="font-weight: 400;">Escherichia coli</span></i><span style="font-weight: 400;">,” was included in the </span><i><span style="font-weight: 400;">Journal of Molecular Graphics and Modelling</span></i><span style="font-weight: 400;">. This international publication features papers on the use of computers in theoretical investigations of molecular structure, function, interaction, and design. It covers all aspects of molecular modeling and computational chemistry.</span></p><p> </p><p><b>References:</b></p><p><span style="font-weight: 400;">Salas, R. L., Sabido, P. M., &amp; Nellas, R. B.
