You hide in the dark and deep,
     Then come out into the open;
You sail the seas along with ships;
     Or stay lurking at the bend.

Seemingly you're tame and kind,
     As you roam free in the wild,
Your music from pipe and lyre,
     Tempting, lovely and mild.

Sometimes you come to our call
     To scare naughty children,
To temper them brave and tall,
     In finding you their friend. ~

UST GS Resurrection and Regeneration

Field cricket (Acheta bimaculata) and sand crab can regenerate a lost leg or two, including the large hind legs, and pincers (crab).  Starfish when cut in half through the central disk will regenerate into two, each with complete arms .  

Old folks tell us of the magic of lizards growing new tails, crabs regaining lost claws, starfish arising from body pieces. How can we explain the mystery behind these stories?

The biological phenomenon behind these stories is called regeneration.

The male deer grows a new set of anthers, and lose them after the mating season. Sea squirts and hydras are produced from tiny buds, so with yeast forming buds. This is the same way plants grow from cuttings, seaweeds grow from fragments, and algae from filaments. New worms may regenerate from just pieces of the body, and some fish can sprout new fins to replace the ones that have been bitten off.

Experiments demonstrated that the forelimb of a salamander severed midway between the elbow and the wrist, can actually grow into a new one exactly the same as the lost parts. The stump re-forms the missing forelimb, wrist, and digits within a few months.

In biology this is called redifferentiation, which means that the new tissues are capable of reproducing the actual structure and attendant function of the original tissues.

Studies on children who lose fingertips in accidents can regrow the tip of the digit provided their wounds are not sealed up with flaps of skin. They normally won't have a finger print, and if there is any piece of the finger nail left it will grow back as well, usually in a square shape rather than round.

Curious the kid I was, I examined a twitching piece of tail, without any trace of its owner. I was puzzled at what I saw. My father explained how the lizard, a skink or bubuli (alibut' Ilk), escaped its would-be predator by leaving its tail twitching to attract its enemy, while its tailless body stealthily went into hiding.

“It will grow a new tail,” father assured me. I have also witnessed tailless house lizards (butiki) growing back their tails at various stages, feeding on insects around a ceiling lamp. During the regeneration period these house lizards were not as agile as those with normal tails were, which led me to realize the importance of the tail.

Regeneration is a survival mechanism of many organisms. Even if you have successfully subdued a live crab you might end up holding only its pincers while the canny creature has gone back into the water. This is true also to grasshoppers; they escape by pulling away from their captors, leaving their large trapped hind legs behind. But soon, like their crustacean relatives, new appendages will start growing to replace the lost ones.

Another kind of regeneration is compensatory hypertrophy, a kind of temporary growth response that occurs in such organs as the liver and kidney when they are damaged. If a surgeon removes up to 70 percent of a diseased liver, the remaining liver tissues undergo rapid mitosis (multiplication of cells) until almost the original liver mass is restored. Similarly, if one kidney is removed, the other enlarges greatly to compensate for its lost partner.

Regeneration of the kidney is in the nephron, which is composed of the glomerulus, tubules, the collecting duct and peritubular capillaries. The regenerative capacity of the mammalian kidney however, is limited as compared to that of lower vertebrates.

How about the human skeleton? The ribs can regenerate with the periosteum, the membrane that surrounds the rib, is left intact. A research was conducted on rib material being used for skull reconstruction. In that particular operation, all 12 patients had complete regeneration of the resected rib. I would not however, relate this feat to Genesis on the theory of creation.

Organ transplantation in higher animals has thus succeeded extensively and is now a regular part in medical practice. Resurrecting the dead however, remains a mystery. Stories in the bible of the raising of Lazarus and the dead little girl remain a matter of faith.

Yet in our postmodern times, a hundred or so ultra rich people lie in cryonics tanks awaiting the time when science shall then have the power to resurrect them. Then there is a short cut to resurrection, so the movie Jurassic Park, make people believe - the reconstruction of the total organism from a piece of its DNA (deoxyribose nucleic acid).

Why such wide and varied aims of man? Not because of man's unending desire for wealth and power, but the belief that the living world has common answer to present day inquiries. For example, is vegetative reproduction limited to plants and protists, why not to mammals? Why are lichens older than most organisms, outliving them by years, if not centuries? Why is a single tissue capable of complete growth to form an entire organism, and that, from this organism another generation arises? If such is the case, then there is no real death of that organism after all. For is it not that life is a continuing process; the DNA is but a continuous stream from one generation to the next, ever young and vibrant, spreading into numbers we call population, and types we call diversity?

Then, if this is so, there is but a shade that separates regeneration and resurrection - or whatever terms we describe the continuity of life on earth.~

UST-AB Photography Review: Happy Faces, Pleasant Views

Dr Abe V Rotor
Floridablanca, Pampanga

Summer is vacation everyday,

and any time is spring;
autumn is just romantic
and winter - if any - is brief;
such is life the greatest art
for the young and happy heart.

Manaoag, Pangasinan

Mingle with the gods and angels under the sun
while childhood and innocence are one.

DZRB radio station, PIA Visayas Ave QC

Confidence and smile - they go on air, too;
invisible they are, yet have wings
that carry the spoken word
and melodious sound,
to the mind, heart and soul.

At home, Lagro QC

Capture in colors and hues,
light and shadow, object and views;
imagination, more than thought -
it is dream that you sought.

At home, San Vicente, Ilocos Sur

Real wealth in bounty and praise,
nature's gift of grace.

Mall of Asia, MM

Forever young - yes, you are,
as young as your heart and mind,
with things that make children
children and hold back the time.

A harvest of guyabano, at home Lagro QC

Remnant of bat or bird, fruits are sweeter;
such is man's fate by his lesser sense,
yet accepts it part of life and game
by competition and evolution.

Parks and Wildlife Center QC

Learn outside the school;
away from shop and mall,
to where Nature is the teacher
the greatest teacher of all.
Dr Anselmo S Cabigan, scientist and professor, with rare bamboo, Lipa Batangas

Teach in situ where Nature is,
where learning is at ease;
teach with wisdom of old,
and learners take what is told.

UST campus, Manila

Loitering is idleness in disguise;
it's keeping with one's pace, too;
for the mind hangs up sometimes,
like the computer, must reset anew.

Atop a guava tree, Floridablanca, Pampanga

Grownups deny childhood,
it comes spontaneously,
surreptitiously -
and innocently.
Anna, Mall of Asia MM

Oh, little brother, little sister,
tell me, who is who,
in the world of animae,
and that of grownups, too.

Anna with parakeets, Safari World, Bangkok Thailand

They come when they're hungry
by two or three;
they come when they like to play,
or seek company.

UST campus Manila

Photography the latest fad
subjects from real to toy;
in takes one into freedom
to find simple joy.

Coed, UST campus, Manila

It matters little if called Doña Aurora
or Doña Trining,
or mythical Medusa transformed;
she is the star shining. ~

Which one is more famous - the Banaue Rice Terraces or the Great Wall of China?

Dr Abe V Rotor
Banaue Rice Terraces, Philippines and The Great Wall of China

I walked the rice terraces
from Earth to moon and back;
on the moon I saw the Great Wall
gray, with color of crimson spill,
cries of Genghis Khan I heard,
and echoes of moaning chill.

I walked the rice terraces round the Earth
many times the length of the Great Wall,
green on one side, golden on the other;
songs I heard are thanksgiving,
in ritual rhythm rise echoing a past, 
a past still living.~

NOTE: Both the Banaue Rice Terrces and the Great Wall of China are among the top wonders of the world and adjudged UNESCO Heritage sites.

Camera - the Third Eye (UST-AB 3CA1, 2, 3, 4)

Assignment: Interpret this article 

A raft lies among the rocks 
as the waves roll forever, 
the breeze hisses in the tree 
in the lazy air of summer.

Love that camera, it's your third eye,
the window to the world in passing; 
as never in another time ever again, 
on this way or that before you die.

When the world is up or down, you go
down the lane and around the bend, 
in times of plenty or dire in comfort, 
the camera shall bring in the rainbow.  

Magic does technology amaze us all, 
work in a lifetime is but a moment,
and the artist is each and every one,
with a little of Da Vinci et al in full.    

Take the road, the sun, make haste,
for having lost your prime and hale,
the lens too, clouds out like the eye,
the window closes. Oh, what a waste!

I walked among young artists in their unique world

Dr Abe V Rotor
Inter-collegiate painting contest held on  the University of Santo Tomas grounds, December 2012.  Note: These photos are unedited. Taken with ordinary palm size digital camera. No flash, no tripod, no filters used.

First, Cubism - 
Cezanne, founder of Impressionism, 
to Van Gogh's crossroad to Expressionism; 
Picasso's three movements to Fauvism 
to Dali's Surrealism.
Silence and quiet -
the artist's unspoken dialect;
eerie to us, and very strange, 
we living on short range. 
                                                                 Beauty in ugliness,
could it be otherwise?
Ask the artists,
the dumb and the wise.
In art there's no time out,
and there's no turnabout; 
wait for the artist's signature, 
his imprimatur.
It is meditation, reflection;
the artist works best 
in the worst condition.
Make a hero, a saint, a queen,
that person who could have been;
not obliging to the throng
even if he may be wrong. 
Singular mind, crowded mind,
would not at all make a difference;
art lives on boundless images to bind, 
on dusty volumes of reference. 
Critics, spectators - 
deep inside a longing 
to be also actors,
wishing, seeking.   
The work is done, the day is gone,
it's worth getting up and retiring;
whether complete or not well done,  
there's no perfect painting.
Where is the artist ?
his paints are fresh, 
his brush idly sits - 
he deserves a rest.
One last look - near and far -
which has a better view?
look again but refrain
from too much review.  
Respite - to us, it's recess; 
take it easy, have composure,  
when too much stress
steals away the picture. 
Late to start? 
not always to the smart;
art takes time to incubate,
 on canvas to recreate.    
Finishing touches,
prudence, prudence,
one false move loses
the whole essence.  
Giving up  ones art?
Absurd? Hark! 
artist and his art
shall never part. 
The contest closes with the day,
leaving the world on canvas to say,
our prayer of thanksgiving,
in each artist's painting.
