Epic voyage and potteries: an ancient connection between the Philippines and the Marianas
by nath in Imprints of Philippine Science
Harvey Pascua and Ronald Ortiz* both live in the Marianas. They share the same first name/surname structure. They look alike. They are both Roman Catholics. But they have different nationalities. Harvey is Ilocano from Cagayan. He is an Overseas Filipino Worker since 10 years ago. Ronald, on the other hand, is a Chamorro, a native [...]... Read more »

Earth week 2012: Pinoyscincus, and its hemipenis
by nath in Imprints of Philippine Science
Or a post previously titled, “Revision of the genus Sphenomorphus.” My last post for Earth week 2012 is about the review of the species-rich genus Sphenomorphus. “Sphenomorphus currently serves as a “wastebin taxon” for a large number of skinks”, according to wikipedia. The authors note that “(1) previously recognized species group relationships were misled by phenotypic convergence; (2) [...]... Read more »

Earth Week 2012: A true colorless cave crab from Samar
by nath in Imprints of Philippine Science
My second post for Earth week 2012 is about a lone new species in a new genus that is most probably found only in Principe cave at the southern tip of Samar island. Recently, the world was awed by the 5 new species of purple crab found in Palawan (link here and here). Here, I present the first [...]... Read more »

And so I’m making it an Earth week. There are 3 research articles about new species and new genera from the Philippines lurking in my laptop. These new species did not make the mainstream media, unlike this and this, but their discovery is just as exciting as the more famous species. Since I decreed this [...]... Read more »

Distinguishing children with mild autism via EEG tracings
by nath in Imprints of Philippine Science
This is a science story of an inquisitive high school student from the Philippine Science High School who by asking the help of the right people [1], may have found a route to differentiate children with mild autism using Electroencephalogram (EEG) traces.

Two new forest lizards: the little one and Leonard’s
by nath in Imprints of Philippine Science
Sometimes, it pays to have a second look. Two lizards are recently identified as new species in two separate publications by a group of Herpetologists from the Philippines and the University of Kansas [1,2,3]. These are the Luperosaurus angliit, or the Little Forest-flap Gecko of Northern Luzon, and the Gekko coi, Leonard’s Forest Gecko of Sibuyan Island. [...]... Read more »

Cleaning an Amorsolo: A new digital cleaning technique for oil painting
by nath in Imprints of Philippine Science
A painting degrades overtime because of different chemical and physical processes. The degradation may be due to some dirt or dust, or light exposure which hastens the usual deterioration of the chemicals used in the paint.
Physical cleaning of the painting is one of the ways to bring the painting back to its original state. A problem though arises because physical cleaning of the painting is mostly subjective. There are no clear standards of restoration and it is pratically trial and error........ Read more »

Mangrove forest distribution of the Philippines
by nath in Imprints of Philippine Science
Here’s a quick post on the mangrove forest covering of the Philippines circa 2000. In an article published in Sensors [1], J.B. Long and C. Giri of the USGS mapped the mangrove forest distribution of the Philippines. They used the publicly available Landsat data (mostly from the Global Land Survey). By mapping out the spatial distribution of [...]... Read more »

A new Gollum shark from Sulu Sea
by nath in Imprints of Philippine Science
Probably one of the best ways to find a new species of shark is to look in your local market. Some weeks ago, there was Squalus formosus in Taiwan and two years ago, there was the Jimbaran shovelnose ray of Indonesia. Now there is a new Gollum shark found in the Puerto Princesa market in Palawan as written [...]... Read more »

Testing the meaning of the Calatagan pot inscriptions
by nath in Imprints of Philippine Science
In my previous post I have presented the ‘tentative’ reading of the Calatagan pot inscription by Guillermo and Paluga [1]. In this post, I write the authors’ test that made them endorse their reading.
The authors think that the reading should be tested by the following: 1) lexical coherence and simplicty; 2) historical emplotment; and 3) sociological mapping or embeddedness.... Read more »

There are so many articles about Fe del Mundo, the Philippines’ first national scientist. You could read her biography here. Most of these articles if you google her will tell you that she invented a bamboo incubator and a sort of jaundice relieving machine.

Subgenus Megapomys: Biogeography and the authors’ concluding remarks
by nath in Imprints of Philippine Science
The genus Apomys (Philippine forest mice) is proposed to be divided into two subgenera: Apomys and Megapomys based on the findings of the Heaney expedition [1]. Megapomys includes A. abrae, A. datae, A. gracilirostris, A.sacobianus, A. aurorae, A. banahao, A. brownorum, A. magnus, A minganensis, A. sierrae, and A. zambalensis. See previous post. The discovery isn’t serendipitous. The authors used predictive biogeographic models that are [...]... Read more »
