Philippine young scientists also went for the Moore at the international science & engineering fair

Around 1,500 high school students from around the world including our own Team Philippines 2012 of eight young science researchers departed for the Intel International Science & Engineering Fair (Intel ISEF) held recently (May 13-18) in Pittsburgh, PA all dreaming of the Moore.

The Gordon E. Moore award of $75,000 from Intel and the Society for Science & the Public (SSP) "recognizes the Best of the Best among outstanding students from around the world who participate in the Intel ISEF."  The next two Bests get the Intel Foundation Young Scientists Award of $50,000 each.  The candidates for awards can be an individual researcher or a team of at most three members.

Before they could qualify for the three Best of the Bests, the young scientists vie for four grand awards and the Best of Category in 17 science research categories. The Philippine young scientists were in four:  environmental sciences (EV), environmental management (EM), engineering-materials & bioengineering (EN), and medicine & health sciences (ME).

It may not be the first grand or Best of Category award, but the fourth grand prize in environmental sciences that Hazel Anne Hernandez, Julian Paolo Biyo and Paul Caesar Flores of the Philippine Science High School-West Visayas Campus won is recognition enough for the difficult work they put into 'regenerating coral fragments on bamboo artificial reefs.'   The Consortium for Ocean Leadership also lauded them for this outstanding work with a certificate of honorable mention.

Prior to the Intel ISEF, these young marine scientists won the Outstanding Young Scientists Award, the top prize in the SEAMEO (South East Asian Ministers of Education Organization) 8th Regional Congress held on March 6-9, 2012.

The three had the Banate Bay in the southeastern part of Panay Island as their marine laboratory. But first, they had to go through rigorous SCUBA diving training before they could dive for and recover broken Acrophora and Stylophora coral fragments from the dense coral reef in the Hibotkan Rock Marine Reserve area.  They had to transport these by boat four kilometers away to the Anilao waters where they deployed concrete and bamboo artificial reefs (CARs and BARs).  This is an area where "no coral assemblages are found."  They've actually started building a reef there, hopefully  to become a new fishing ground esp. for local fishermen who helped them deploy the artificial reefs.

Hazel, Julian and Paul had to dive every month from February to December 2011 to check if the coral 'transplants' could survive and grow on the artificial reefs, measuring their growths as well as the water quality obtaining there.  

"Acropora and Stylophora coral fragments can be transplanted on both concrete and bamboo artificial reef," they reported, "[although] Acropora showed low survival and growth."  They're enthusiastic about the use of bamboo as a material for an artificial reef construction because it is abundant and easily obtainable in the area.

Their 'marine laboratory' has been declared a marine protected area, a no-fishing ground by the local government of Anilao town.  In their dive before flying to Intel ISEF, they already noted an increasing diversity of marine life there.

The other members of Team Philippines 2012 may not have come home with grand awards but they too had outstanding research studies to show off at the Intel ISEF.

Elson Nyl Galang of PSHS-Southern Mindanao campus (Davao City) brought with him eight meters of what he calls 'eco-fabric from fragrant screw pine (Pandanus amaryllifolius) leaf fibers.'   In his study, he was looking for a natural fiber to replace polyester to blend with cotton in producing a Philippine Tropical Fabric (PTF). 

He had the full support of the Philippine Textile Research Institute (PTRI) where he did his project while he was in summer internship there.  His product, a blended cotton-pandan fabric (80-20%), was found "to have the fabric weight ideal for blouses and pants, good breaking strength, exhibits shrinkage, has low pilling resistance, good colorfastness and non-staining ability."

Elson's pandan fibers have now joined four natural fibers that are being used to produce PTFs: Musa textile (abaca), Musa paradisiaca (banana),  Ananas comosus (pina), and silk. 

Ven Gabriel Tan from Marinduque National High School was intrigued by the proliferation of common herbal plants in a mine brownfield, an area that has been abandoned because the soil is heavily polluted by heavy metals, and in this case, copper ions, Cu+2 . He thought of studying the 'potentials of [these] common herbal plants in sequestering copper in former mine brownfields.'

He chose to study four plant species, namely, Amaranthus spinosus (local urai, Eng.pigweed), Desmodium heterophyllum (Desmodium), Ruellia tuberose (meadow weed) and Stachytarpheta jamaicensis (local kandikandilaan), planting them on three soil set-ups--plain garden soil, garden soil amended with high level of copper in solution, and actual soil from the former mine site.  

"All the plant species can hyperaccumulate Cu+2 within the range of 2 to 100 ppm," Ven reported. "They can be used in phytoremediating these ions in mine fields."  During the experimentation period, he noted that the plants did not wilt nor the leaves turned yellow; indications that they could tolerate the high concentration of Cu+2 in the soil.

Ven said their local government has taken interest in his research.  He hopes that his study could help local officials craft policy guidelines for environmental management there.

 A marine creature, the sea hare ('donsol' in Sarangani) or Dolabella auricularia was the subject of scientific interest to Carla Beatriz Lazara, Lanz Gabriel Jabla and Bryce Abraham Anos from the PSHS-Southern Mindanao campus.  They were particularly intrigued by the purple ink that it secretes to ward off predators.  They thought this secretion "may contain substances with pharmacological applications."

Thus, their 'bioprospecting for active compounds of Dolabella auricularia (sea hare) ink secretion' had them perform tests to characterize this substance.  The genotoxicity assay told them that the ink enhances mitosis in the Allium cepa (onions), which was evident in the proliferation of long roots during the experimentation period.  They found out however that the ink has cytotoxic effect on Artermia salina (brine shrimp).  They were able to confirm the presence of secondary metabolites in the sea hare ink, which include flavonoids, leocoanthocyanins, saponins and tannins.

Carla, Lanz and Bryce wrote that "isolation, identification and characterization of the bioactive compounds ... may be explored to determine components with therapeutic benefits," and that further cytotoxicity studies "may provide better use of the sea hare ink in the development of pharmaceutical products."

All except Ven Gabriel will be university freshmen when school opens.  Ven will be in his senior high school year, and with his exposure in the Intel ISEF 2012, he may yet come out with a winning project to bring to the Intel ISEF 2013 in Phoenix, Arizona in May next year.
