Good morning.

 

It is with great pleasure and pride that I receive the Concepcion Dadufalza Award for Distinguished Achievement. I hope that my accomplishments as a scientist and UP faculty member adequately reflect the ideals of this award.

 

I participate in award competitions like the Dadufalza Award and Gawad Chanselor for two reasons: 1) To gauge the progress that I have made as a scientist relative to those of my colleagues in the community; and 2) To help develop an effective merit system for the University that rewards competence, depth, and craftsmanship over jargon, sense-impressions, and gimmickry. Scientific tradition could not take root in a society that is incapable of executing a fair and just promotion system that is based on merit alone. Those who prefer to work in their cramp research laboratories over the comfort of a carpeted office, have to be assured that their worthy efforts will not remain unrecognized by the University and the community at large.

 

It is important to mention that the University of the Philippines through the tireless efforts of President Nemenzo and Chancellor Roman, is heading towards instituting a proper promotion system and generous incentive schemes to encourage the pursuit of excellence in the UP system in general and the Diliman campus in particular.

 

My research interest is in signal processing. I take advantage of the principle that the image that we see is not an exact replica of the object of our investigation. The image is the output of a measuring instrument and the object is the input. Some information is often lost during physical observation because no measuring instrument is perfect. It is a fundamental fact of optics that the image of a point object which has no spatial dimensions, is always larger than a point. This means that two closely-spaced biological cells may not be observed correctly and my job is to develop detection and signal recovery techniques that will enable us to determine that indeed, there are two cells on the microscope slide and not one and one-half.

 

I am fortunate to have developed over the years a “sixth sense” and a fair amount of expertise in measurement science which afford me to explore a wide range of phenomena in nature. There is no science without measurement and therefore research opportunities that are at hand for my research team are numerous i.e. if we do not fail to recognize them quickly.

 

It is worth pointing out that I came into instrumentation research primarily by chance and circumstance. More than ten years ago, during my time as a graduate student, signal processing research was non-existent at the National Institute of Physics and people probably thought of it as a trivial alternative for those who could not solve abstruse assignments in theoretical physics. Indeed, ignorance is bliss!

 

Of course it helped me greatly to be a graduate student at a time when computing power started to become available to mere mortals. Thanks to the vision of Steve Jobs and the technical genius of Steven Wozniak of Apple Corporation.

 

Please permit me now to share with you my expectations of the Filipino scientist. Many of these expectations were already with me maybe in their more primitive forms about 24 years ago when I first set foot on the grounds of this University. During those times, they were a constant source of optimism for the future.

 

I expect the Filipino scientist to contribute towards establishing a scientific culture in the Philippines. I count on him or her to become part of a rich scientific tradition that all Filipinos can be proud of. Excellence in pure or applied science is about performing well and consistently. It does not become a way of life in a society that does not have an accurate sense of history concerning the contributions of its scientists and engineers for the advancement of science and technology.

 

Scientific tradition is forged by generations of scientists ceaselessly pushing the limits of scientific knowledge. In this respect, scientific tradition is still in its infancy in Philippine society. Four hundred years ago, Galileo Galilei (1564 – 1642) already performed his classic experiments on freely-falling bodies and established the power of the experimental method in the search for scientific truths. Interestingly in a time where the life expectancy was less than 40 years, Galileo was able to reach the ripe old age of 78 years despite the persecution of the Establishment. In 1666, Isaac Newton (1642 – 1727) already knew that the colors of the rainbow could also be produced by passing sunlight through a glass of water.

 

On the one hand, the Philippine physics community has no recollection of the kind of physics research that was done here in UP and the Philippines at large less than half a century ago. It could be that there was none or that the succeeding generations in the 1960’s and 70’s chose to ignore it. At any rate, it seems to me that the modus operandi is for the current generation to blame the previous one for the prevailing misery. Obviously, this is not the kind of tradition that we would like to take root in our science community – scientific progress is a cumulative process. Newton has to stand on the shoulders of the ‘giants’ before him to be able to see farther away.

 

Scientific tradition is needed to generate the intellectual capital for developing better technologies that will enable our country to meet adequately the increasing pressures of a growing population, dwindling natural resources, and merciless economic competition with other countries. Genuine respect for scholarship and the rooted belief in fair play are natural attributes of a society with a strong scientific tradition.

 

The present lack of intellectual capital will prevent the Philippines from exploiting fully the information that are contained in the various genome maps which are now becoming more accurate and comprehensive literally by the day. These genome databases are available free of charge. Our country simply does not have the pool of tried and tested researchers in the fields of computational biology and biological physics. Our local biologists and physicists are cruising in the wrong areas.

 

The lack of a scientific tradition also prevents us from anticipating accurately emerging “hot” areas in science and technology. Our local scientists have not yet developed the confidence and foresight to venture in research areas ahead of their American, European and Japanese counterparts.

 

Scientific tradition does not emerge by chance in a society. It results from a conscious and coordinated effort by many sectors of society (the industry, government, and the academe) over periods of time. I believe however, that the scientists in the academe play the most crucial role in the task of tradition building. I expect them to lead because they are not beholden to the short-term interests of politicians nor encumbered by the profit-motive of businessmen. They are also directly responsible for the education and training of the future generation of scientists and intellectuals of society.

 

Scientific tradition can not take root in our land if our scientists do their research abroad. While working in America, Germany, or Japan may be advantageous to the handful of individuals who are fortunate enough to find jobs or develop lasting connections with foreign counterparts, it will not teach our scientists the values of resilience, resourcefulness, self-respect, and perseverance. These are essential values which enable our local scientists to rise above the unfavorable circumstances that deter the pursuit of excellence in our country.

 

Scientific research is very difficult to perform in the Philippines – the supporting research infrastructure has not yet been sufficiently developed. Doing research in the Philippines is like wading through muddy waters – one small step forward takes so much effort. This is the reason why those who have chosen to take this risky path are worthy of our financial and moral support. They are the ones who will develop the infrastructure needed to deliver a high probability of success in a scientific endeavor.

 

The graduate school is the defining element of a great institution of higher learning in science and technology. It is the quality of the Ph.D. degree program not the B.S., nor the M.S., that sets the reputation of a science department. This is because a Ph.D. degree is a research degree and the scientific enterprise is geared towards extending the boundaries of our understanding of the natural world which is the goal of research. Whether we like it or not, the reputation of a University is built upon the number of scientific publications and patents that are being produced by its faculty and staff. No one has ever been awarded the Nobel Prize in Physics, Chemistry, or Medicine without publishing at least one original scientific paper. Not even the great Albert Einstein who received the Prize in 1921 for his work in the photoelectric effect and quantum theory.

 

The graduate school programs in our science and engineering departments including that of the National Institute of Physics, have remained weak despite the efforts to strengthen them in the last 35 years. Noteworthy improvements have occurred in the marine sciences and in optics and computational physics especially in recent years but these cases are isolated and the advances have remained fragile. The sad fact is that most of the full professors and associate professors in our science and engineering departments are not publishing consistently in refereed U.S. or European journals. Only a few have experienced reviewing manuscripts for international journals. Thus, not all of our faculty and staff have the necessary understanding of the nature of quality research and how it is done.

 

Scientists in the academe are expected to supervise Ph.D. students and the most serious weakness of our graduate programs is the perennial lack of competent Ph.D. supervisors. Their presence is needed to attract the best young minds to finish their Ph.D. degrees in U.P. instead of somewhere else. By providing a reasonable option to stay, these Ph.D. supervisors will be able to contain the diaspora of Filipino scientific talents to the G-7 countries. The brain drain is not diminished through hallow speeches, abstract policies and ineffective programs that redirect our young scientists to administrative jobs.

 

That our B.S. graduates could easily find assistantship positions or scholarships in U.S. or Japanese universities is not a manifestation of success for a science or engineering department. On the contrary, it is an indication of its failure to retain their most promising B.S. graduates.

 

What are my expectations of a competent Ph.D. supervisor? He or she must be in the forefront of his area of interest. This implies that he publishes regularly in an ISI-abstracted journal that is widely-read by his peers. I expect a professor of physics to publish at least three ISI papers a year on average regardless of administrative duties and responsibilities. I also expect him to include all his collaborators in the authorships of a research manuscript regardless of whether it is for a conference presentation or for submission as a full journal article.

 

I expect the scientist to know that no area in science and technology is more important than others. In the same token, no scientific discipline is more difficult than others. A scientist should not blame his field for his poor research performance. Doing so is like a ship captain complaining about the sea.

 

The skill and confidence of a Ph.D. student are acquired through long hours of experimentation and analysis, and regular interactions with his supervisor and fellow students in research meetings and seminars. His training is a shared experience that is also beneficial to his research supervisor. The life of a scientist no matter how accomplished he might be, is always marked by daily attempts to understand Nature more clearly and accurately.

 

What can be done to increase the number of competent Ph.D. supervisors in the University? There seems to be a few additional changes that the University needs to implement in addition to the incentive schemes that are already in place.

 

Promotions in academic rank must be de-coupled from salary promotions that arise from mere longevity of service to the University. A faculty member need not become a full professor in order to earn a salary that is equal to what a young and productive full professor is receiving. The University must limit the number of full professors in each department or institute. This number can be pegged on the number of legitimate research laboratories existing in the unit.

 

A research laboratory is recommended for abolition if it does not produce a minimum number of ISI publications and patents within a given period of time. In such a case, the professor who responsible is either transferred or retired early. This policy will provide a science or engineering department with the flexibility to open new laboratories without seriously compromising its research budget.

 

Academic ranks should not be trivialized for economic reasons. With the low salaries, our academic rank is one of the few precious possessions we could cherish about.

 

The research performance of our science or engineering departments and institutes must be evaluated by an independent panel every three years using a well-defined set of criteria. We note that three years is the term of an Institute Director. The best performing institutes will be granted an increase in their research budget allocations for operational expenses, equipment acquisition, and infrastructure development.

 

In-breeding is an issue that is raised for academic units that employ as faculty members their own Ph.D. graduates. This is a serious problem with direct implications to our objective of attracting the best young minds into our own graduate programs. Due to the increasing number of the student population and the lack of Ph.D.’s applying from abroad, our academic units have no other choice but to hire its own Ph.D. graduates.

 

In-breeding is probably present in a department when a number of its faculty members is engaged in research projects that are mere extensions of those that were done by their Ph.D. supervisor before them. This may still be acceptable if these projects lead to publications in ISI-abstracted journals – some research topics simply remains interesting no matter how long have they been mined.

 

A fatal effect of in-breeding is the formation of warring factions in a department by faculty members of the same Ph.D. pedigree. I do not venture out of the National Institute of Physics much so I do not really know if such a debilitating scenario happens in other units of the University.

 

Ways maybe instituted to reduce in-breeding. One is to grant a Ph.D. degree to a student only after his or her publication of three (or more if you like) papers in ISI-abstracted journals. The earlier the topic is beaten to pulp the more chances that it will not be able to rise up again.

 

Another is to send immediately the more talented Ph.D. graduates whom the University is more likely to hire to postdoctoral studies for not more than two years, in established research centers in the U.S., Japan or Western Europe. Such a move which the Nemenzo administration has pioneered, will expose the Ph.D. graduates to other possible research topics and ways of doing things. A word of caution: they should not be sent to universities where their Ph.D. supervisors came from!

 

I also expect the Filipino scientist to be aware of his responsibilities to society at large. Research is a high-risk activity and the scientist could rely mostly on the financial support of government which has to decide between buying a femtosecond laser or sardines for typhoon victims in Samar. He must know how to spend public funds wisely by acquiring equipment and components which are of immediate use to more scientists in the community.

 

In summary, I expect the Filipino scientist to overcome the adversities that face him in his struggle to do research in the Philippines. Some of the tools that are needed have been discussed in this lecture. I admit that the task is difficult but it is not impossible and the fruits of a hard-earned victory are much sweeter because they are shared with people who are not merely our students or collaborators but more significantly, our blood brothers and sisters who share with us the same set of aspirations and dreams for our nation.

 

Thank you very much for your time and attention.

Over 100 research papers from MSI scientists were presented at the 17th National Symposium on Marine Science, which was held from July 20 to 22 in Batangas City under the theme, “Saving Our Seas: Restoring Marine Systems for People and Nature.” It was sponsored by the Philippine Association of Marine Science (PAMS). 

 

Dubbed simply as PAMS 17, the national symposium follows closely on the heels of the World Meteorological Organization’s warning that global sea surface temperatures hit all-time record highs in June. The extensive scope of the UP researchers’ work underscores the importance of marine science in national security and nation building.

 

The keynote speaker, Dr. Gil Jacinto, who retired from the MSI in 2020, highlighted the importance of the country’s researchers in his speech, “Philippine Marine Science: Navigating the Ocean Decade towards 2030.”

 

“Symposiums like PAMS give UP MSI an opportunity to share results and best practices to other researchers,” said MSI Deputy Director for Research Dr. Deo Florence Onda. “The discussions allow us to build on what we already know, help others progress in their own work, and learn from feedback on how to improve further.“

 

“Moreover, PAMS strengthens camaraderie, widens networks, and facilitates future collaborations,” he added.

Skin like butterfly wings: UP scientists investigate rare deadly disease

Skin like butterfly wings: UP scientists investigate rare deadly disease

Published: July 17, 2023

By: Eunice Jean C. Patron

As rare and deadly as it is poetically named, “Butterfly’s Disease” (scientifically known as “epidemolysis bullosa” or simply “EB”) has no known cure. But a handful of Filipino scientists are working their way towards a treatment.

Epidermolysis bullosa (EB) sufferers have very delicate and fragile skin reminiscent of butterfly wings. The disease has many forms, including EB simplex (pictured) as well as the rarer—and potentially deadly—Junctional EB (JEB) that can affect even internal organs. (PHOTO CREDIT: James Heilman, MD | Wikimedia Commons)

EB is a very serious disease, for those afflicted as well as for their families. Sufferers have severely fragile skin that easily blisters and tears even with the slightest touch, hence the comparison to butterfly wings. EB also varies in form, with mild cases that only affect the outer skin to extreme cases that injure even internal organs—an extreme condition that can lead to severe disability or even death. 

 

To further understand Butterfly’s Disease, scientists from the University of the Philippines – Diliman College of Science (UPD-CS) have focused on a genetic mutation known to cause an even rarer type of EB called Junctional EB (JEB), which affects more layers of the skin and can be fatal if it happens during early infancy. 

 

Genetic investigators’ surprise discovery

 

The onset of JEB has been associated with a genetic mutation called G273D that affects how the body produces a protein called ITGA6-ITGB4 integrin (or Integrin A6B4 for short), which plays a vital role in joining together cells and tissues. The G237D mutation causes the production of malfunctioning Integrin A6B4 and decreases the presence of functional Integrin A6B4 on epithelial cell surfaces, leading to weaker cell adhesion in the skin tissue and resulting in severe skin blisters.

 

Molecular biologist Dr. Neil Andrew Bascos and his graduate students, Kim Ivan Abesamis and Camille Anne Bagoyo, of the National Institute of Molecular Biology and Biotechnology (UPD-CS NIMBB) are investigating just how G237D affects the structure of Integrin A6B4.

 

“We weren’t looking to study EB when we started this study,” Dr. Bascos narrated. “The main goal of the research has previously been looking at the function of integrins and their roles in cancer. Interestingly though, we’ve found that integrins may be associated with many other relevant diseases.  Finding its involvement in this disfiguring disease provides us a means through which our research may be able to help the afflicted people.”

 

In their computational study, the researchers investigated how the G237D mutation prevents Integrin A6B4 from forming, and from  binding their targets properly.  Some factors, such as the presence of calcium ions, were also observed to stabilize integrin interactions.

 

Paving the way for future research

 

The study sets the direction for further research into factors that can alter the effect of the G237D mutation on Integrin A6B4 function. Exploring these factors can pave the way for discovering cures for EB. “At this point, it’s very much basic research, medyo predictive pa. It would need proof of principle, but these studies give us concrete targets to test in the search for ways to alleviate the disease,” Dr. Bascos said.

 

Some people with EB die as infants. Others manage to survive, but suffer from chronic illnesses that stem from its effects.  Although little is currently known about effective treatments and cures for Butterfly’s Disease, the UP scientists remain steadfast in their quest to gain a deeper understanding of EB, in hopes of improving the quality of life of these patients and their families.

Survey confirms disappearing population of critically-endangered Irrawaddy dolphins in Bicol

Survey confirms disappearing population of critically-endangered Irrawaddy dolphins in Bicol

Published: July 12, 2023

No sooner has their existence been confirmed that the rare Irrawaddy dolphins (Orcaella brevirostris) of San Miguel Bay in Bicol are already at risk of disappearing from the region.

Irrawaddy dolphins are characterized by gray or dark-blue backs and pale bellies, with a high tolerance to various levels of salinity that enables them to live in areas where salty seawater and freshwater meet – such as in the mouths of rivers and bays. They are among the world’s most endangered dolphin species, indicated as critically endangered on the Red List of the International Union for Conservation of Nature (IUCN). They are also considered critically endangered by the Philippine Department of Environment and Natural Resources (DENR). 

 

A mission to find live Irrawaddy dolphins in the area of San Miguel Bay in Bicol led scientists from the University of the Philippines – Diliman College of Science Institute of Environmental Science and Meteorology (UPD-CS IESM) to validate the existence in the area of this critically-endangered species during a recent dolphin survey conducted from July 6 to 9, 2023.

 

Efforts to locate Irrawaddy dolphins

 

The team, led by IESM Professor and Marine Mammal Research and Conservation Laboratory (MMRCL) Head Dr. Lemnuel Aragones, sighted two Irrawaddy dolphins—one near Canron Island and another near Canimog Island, both in the waters of Mercedes, Camarines Norte.

 

“These dolphins prefer brackish waters, making the San Miguel Bay area an ideal place for the Irrawaddy dolphins to thrive, with its shallow depth, a wide range of salinities, and presence of nearby offshore islands,” Dr. Aragones explained.

 

The IESM researchers and the Bureau of Fisheries and Aquatic Resources Regional Office 5 (BFAR5) were motivated to organize the dolphin survey after conducting key informant interviews in October 2022 about a stranded Irrawaddy dolphin reported as a bycatch in August of the same year. 


The team covered a total area of about 680 square kilometers. In terms of travel distance, they covered a total of 335 kilometers in 23 hours, spread over four days, with transects traversing the shorelines of towns in Camarines Norte and Camarines Sur. 


Seeking refuge in San Miguel Bay


According to Dr. Aragones, not only do these rare sightings of Irrawaddy dolphins confirm their existence in San Miguel Bay, they also indicate that only a few of these dolphins are left. “It is most likely that the Irrawaddy dolphins are using the offshore islands in the San Miguel Bay as a refuge area, and that there is now probably much less food for them there since it is one of the most over-exploited fishing grounds in the country,” Dr. Aragones explained.


Dr. Aragones also urged the creation of an action plan with BFAR5 on the protection and conservation of these critically-endangered dolphins. “I already talked with BFAR5 Regional Director Ariel Pioquinto about enhancing San Miguel Bay again to ensure the Irrawaddy dolphins’ habitat,” he said. “We hope to harmonize local ordinances with existing national laws regarding protected species.” 


The dolphin survey team was composed of spotters from IESM; the BFAR5 – Fisheries Protection and Law Enforcement Group (BFAR5-FPLEG); the BFAR – Fisheries Resources Management Section (BFAR5-FRMS), and the Ateneo de Naga University Institute for Environmental Conservation and Research (INECAR).


Other populations of Irrawaddy dolphins in the Philippines can be found in Malampaya Sound in Palawan and the Iloilo-Guimaras-Negros Occidental area.

AI-powered Baybayin translator being developed by UP mathematicians

AI-powered Baybayin translator being developed by UP mathematicians

Published: July 11, 2023

By: Eunice Jean C. Patron

Filipino mathematicians have just invented a computerized method for converting entire paragraphs and even full documents written in the ancient Filipino Baybayin writing system into text that even non-native readers can easily understand. And they’re now hard at work developing a full two-way translator.

By combining mathematics and technology, scientists from the University of the Philippines – Diliman College of Science Institute of Mathematics (UPD-CS IM) have made what is likely the world’s first paragraph-level optical character recognition (OCR) system that can distinguish between entire blocks of Baybayin and Latin characters in a text image. 

 

Thousands of images, months of hard work

 

In their paper entitled “Block-level Optical Character Recognition System for Automatic Transliterations of Baybayin Texts Using Support Vector Machine,” masters student Rodney Pino and associate professors Dr. Renier Mendoza and Dr. Rachelle Sambayan developed an algorithm to convert a photograph of a set of text into binary data, which is then run through a support vector machine (SVM) character classifier to automatically determine whether the characters are Baybayin or Latin.

 

“SVM is a machine learning algorithm used to solve regression or classification problems,” Pino explained. “We have a dataset for Baybayin characters—let’s say character A and then character BA. SVM uses techniques or mathematical methods that can separate the two datasets to determine characters BA and A.”

 

It took the group more than three months to collect over a thousand images for each Baybayin character, gathering a total of 110 paragraphs from different websites that have either hand- or typewritten Baybayin, Latin, or Baybayin and Latin writing. “Adding more character images improves the recognition rate of SVM,” Pino explained.

Developing a smart, two-way translator


Currently, the OCR system can spell out the Latin equivalent of the Baybayin characters on a page, thus producing a transliterated version of the text. But the researchers are looking to enable it to do so much more.


The mathematicians also plan to make the OCR system more aware of the context of Baybayin words and phrases, possibly paving the way for a full-fledged translator. They are also trying to make the system work both ways, with the ability to convert Latin words with foreign sounds into Baybayin.


“We’re trying to refine the software we developed to make it easier for future users to navigate it. We also dream of creating a mobile application that automatically and accurately translates Baybayin characters just by hovering over the phone,” Dr. Mendoza said.


However, there are some kinks to smoothen out: Dr. Mendoza said that it was challenging to get the OCR system to translate Baybayin words and sentences accurately. “For now the system can’t distinguish between some Baybayin characters that are similar in writing, such as E and I, and O and U. We also have a lot of words that have different Latin equivalents,” he expounded. “The algorithm we used shows all possible translations of the Baybayin words.”


Preserving Filipino writing systems


Although still scant, interest in and research on Baybayin is slowly increasing, making the mathematicians hopeful that more Filipinos will become interested in protecting Baybayin through research. The team published their data to encourage more researchers to conduct studies on Baybayin and OCR. “We cleaned the data in such a way that researchers could use it in analyzing Baybayin through other algorithms,” Dr. Mendoza shared. “We made the data readily available for use, so researchers wouldn’t go through the difficulty we experienced in gathering data.”


Philippine traditional writing systems, such as Baybayin, are representations of Filipino tradition and national identity. As such, the country’s government officials created the “Philippine Indigenous and Traditional Writing Systems Act,” which seeks to promote, protect, and preserve Baybayin and other traditional writing systems.


The proposed law urges using Baybayin as a tool for cultural development and safeguarding, therefore encouraging organizations and institutions to spearhead activities and projects that promote awareness of these traditional writing systems. 


According to the scientists, Baybayin is living proof that we Filipinos have our own technically-sophisticated traditions. While they aren’t putting forward making Baybayin the Philippines’ primary writing system, the group believes that conducting more research on Baybayin will help preserve this heritage. “This can be forgotten,” Dr. Sambayan said. “It’s important to have a record of each Baybayin character—even having digitized ones.”

Dr. Sambayan expressed concern that the number of Filipinos who can read and write Baybayin is decreasing, adding to the importance of identifying and translating Baybayin characters into Latin. “We’re hoping that through this OCR system, we could preserve and pass on the knowledge of understanding Baybayin to future Filipino generations,” she said.


Baybayin and other traditional writing systems are a part of the Philippines’ rich history. Several old Filipino documents are in Baybayin—documents that can uncover more information about Filipino culture. The scientists are encouraging more Filipinos to join them in cultivating the body of knowledge the country has on Baybayin. “Kapag walang gagawa nito, sinong gagawa? Even though its implication already has a bit of a niche, I think this is still a vital research venture,” Dr. Mendoza said.

The UPD-CS IB has partnered with the Changjiang River Scientific Research Institute (CRSI) of China’s Changjiang Water Resources Commission (CWRC) on a joint project entitled, “Construction and Demonstration of Water Conservancy Combined with Schistosomiasis Control (WCCSC) in ASEAN Countries,” with support from the Asian Cooperation Fund.

 

Schistosomiasis is an often-neglected tropical disease that greatly impacts many agricultural villages in the Philippines, particularly poor and marginalized communities. In 2019 alone, it was reported that the disease affected some 12 million people across the country. The joint project aims to demonstrate the impact of water conservancy technology on the control of the snail vector of schistosomiasis in selected endemic villages in Leyte. The team will provide training to local health workers and engineers in the principles and applications of WCCSC.

New findings from a cave in northern Laos add to a growing body of evidence that modern humans arrived in Southeast Asia over 80,000 years ago, tens of thousands of years earlier than previously thought. The groundbreaking findings were recently published in the prestigious journal, Nature.

Analyses of fossils and sediments from Tam Pà Ling (“Cave of Monkeys” in Lao) by an international team of scientists—including a Filipino researcher formerly from the University of the Philippines (UP) and currently at the Flinders University Microarchaeology Laboratory in South Australia—has pushed back the time when we know our species, Homo sapiens, was present in Mainland Southeast Asia. 

 

The newly-discovered fossils provide unmistakable evidence of the presence of modern humans in northern Laos as far back as 86,000 years ago. This is almost 20,000 years older than most of the evidence from sites so far studied in Southeast Asia and adds further confirmation of a pre-60,000-year-old dispersal of modern humans into East Asia. 

 

“This discovery is helping us better understand the distribution of our direct ancestors at a time when we know other populations of humans, now extinct, existed,” said Vito Hernandez, the Filipino geoarchaeologist who is part of the team that published these recent findings from Tam Pà Ling.

 

This research in northern Laos, including a previous discovery of now-extinct humans known as Denisovans present between 164,000 and 131,000 years ago in Tam Ngu Hao 2 (“Cobra Cave”) located in the same mountain as Tam Pà Ling strongly suggests that this part of Southeast Asia is an early human dispersal route. “This  proves that our human ancestors also traveled along forests and river valleys apart from following islands and coastlines as they moved eastward to Australia, where they are controversially thought to have migrated as early as 65,000 years ago,” Hernandez explained. 

 

“Analyses of the fossils in Tam Pà Ling suggest that these early modern humans were part of an immigrant population, but whether their genetic line successfully survives in current populations is yet to be determined,” he added.

 

Initially, fossils from Tam Pà Ling were hard to date, resulting in skepticism about previously-presented evidence from the cave. This led the geochronology and geoarchaeology specialists of the team to strategically apply their techniques to ascertain how the dated sediments relate to the fossils, and determine a precise age for both. 

 

“The dating and the quality of fossil preservation is important as we’ve seen from research led by scientists like Professor Armand Mijares at the UP School of Archaeology, but as we’ve also seen from our research and other human evolutionary research like in Denisova cave in Russia, a very close collaboration between the Earth and Human sciences is necessary if we are to achieve a more complete picture of how humans evolved and settled into different parts of the world,” he elaborated.

 

Hernandez was formerly part of the UP Archaeological Studies Program, now the UP School of Archaeology, where he obtained his Master of Science and taught undergraduate classes in Archaeology. He was also part of the Science and Society Program of the UP Diliman College of Science (UPD-CS), where he managed classes in Science, Technology and Society. “I hope to return after my research work in Australia and contribute to making our science serve Philippine society,” he concluded.

Monitoring the health of marine environments is a laborious activity, but is essential for evaluating the success of reef protection and rehabilitation initiatives. A fish census commonly involves divers swimming along a transect line, usually marked by a plastic cord, and visually counting and identifying the fish species that they encounter. This painstaking process requires trained experts and highly knowledgeable divers to accurately record data on species, size, and abundance.

 

In 2016, Dr. Laura David of the University of the Philippines – Diliman College of Science Marine Science Institute (UPD-CS MSI), together with co-author machine intelligence expert Prof. Prospero C. Naval, Jr. of the UP Department of Computer Science (UPD-DCS) presented a conference paper entitled, “FishDrop: Estimation of Reef Fish Population Density and Biomass using Stereo Cameras” which proposed a semi-automated method that combines a stereo camera rig and image recognition software to allow for more efficient and accurate reef fish census. 

 

The proposed technology would enable divers with minimal training to obtain high-quality population and species distribution measurements using the specially developed stereo camera rig and fish video analyzer software.

 

FishDrop promises to help improve the Philippines’ reef resilience and biodiversity restoration efforts, and contribute towards the overall health of the country’s reef ecosystems.

This coming Monday, June 26, Dr. David is set to take the iStories stage to expound on ‘FishDrop’ and share their team’s journey not just in developing the technology, but also in successfully translating this groundbreaking innovation into a patent. 


“Perseverance is necessary to get the concept and the product translated into a patent and commercial venture. It has not been an easy road,” says Dr. David. Like any other intellectual property and patent applications, the journey for FishDrop has been tedious, nevertheless rewarding. Dr. David hopes that through her sharing, she may inspire others to persevere with their own scientific endeavors despite the trudging process.


iStories is a series of innovation-themed talks, storytelling, and activities featuring local and international scientists. The initiative aims to ignite the creativity and inventiveness of young scientists not just from UPD-CS but from other institutes inside and outside UP.
