MIND-BOGGLING FISH

             Few fish grab our attention the way the clown fish does. Perhaps it wins our hearts with its fancy coloring, which may remind us of a circus clown. Or maybe we are struck by its surprising choice of home –among the stinging tentacles of a sea anemone. Not surprisingly, another name for the clown fish is anemonefish.
            Like many Hollywood actors, clown fish are not averse to photographs. Divers and snorkelers can usually expect clown fish to pose for pictures, since they rarely stray far from home and are not particularly shy.
          But what makes clown fish amazing is their seemingly risky lifestyle. Living among poisonous tentacles would seem to be comparable to setting up home in a nest of serpents. Still, clown fish and their anemone of choice are inseparable. What makes this strange partnership possible and successful?
         Like most good partnerships, clown fish and anemones give and take. The relationship is not merely convenient for the clown fish; it is vital. Marine biologists have confirmed that clown fish cannot live in the wild without a host anemone. They are poor swimmers and would be at the mercy of hungry predators without the anemone’s protection. However, by using the anemones as a home base and as a safe shelter when threatened, the clown fish may reach ten years of age.
          The anemone provides a safe nesting site as well as a home. The clown fish deposits their eggs at the host anemone, where both parents keep careful watch over them. Later, the clown fish family can be seen swimming around that same anemone.
        What does the anemone get out of this relationship? The clown fish serve as marine bodyguards, driving away butterfly fish that like to feed on anemone tentacles. At least one species of anemone cannot live without resident clown fish. When researchers removed the clown fish, within just 24 hours, the anemone had disappeared completely. Apparently, butterfly fish had consumed them.
        It seems that clown fish even provide their host with energy. The ammonium that clown fish excrete helps spurs growth in the host anemone. And as the clown fish swim among the tentacles, they help circulate oxygen-rich water to the anemone.
        In the case of clown fish, protection is skin-deep. They have mucus on their skin that keeps them from being stung. Thanks to this chemical coating. It seems the anemone considers the clown fish one of its own. As one marine biologist put it, the clown fish becomes a fish in anemone clothing.
       Some studies suggest that when selecting a new host, the clown fish has to go through a process of adaptation. It has been observed that when the fish approaches an anemone for the first time, it touches the anemone intermittently for a few hours. Apparently, this on-and-off contact allows the clown fish to modify its protective coating to conform to the new anemone’s particular poison. Possibility the clown fish gets stung a little during this process. But after that, the two get along fine.
       The collaboration of such different creatures offers a fascinating lesson in teamwork. In so many human endeavors, people from diverse cultures and backgrounds achieve remarkable results by pooling their resources. Like the clown fish, we may take a little time to adapt to working with others, but the results are well worth it.

MYSTERIES BEHIND COLOR

-
      I understand how scarlet can differ from crimson because I know that the smell of an orange is not the smell of a grapefruit. I can also conceive that color have shades and guess what shades are. In smell and taste there are varieties not broad enough to be fundamental; so I call them shades…..The force of   association drives me to say that white is exalted and pure, green is exuberant, red is suggests love or shame or strength. Without the color or its equivalent, life to me would be dark, barren, a vast blackness.      Thus through an inner law of completeness my thoughts are not permitted to remain colorless. It strains my mind to separate color and sound from objects. Since my education began I have always had things described to me with their colors and sounds, by one with keen senses and a fine feeling for the significant. Therefore, I habitually think of things as colored and resonant. Habit accounts for part. The...

SNIFFING OUT DISEASES

-
                                       A sniffing test may help in the early diagnosis of diseases such as Parkinson’s or Alzheimer’s. A failing sense of smell appears early in the progression of Parkinson’s disease and is among the most common symptoms. A practical method of testing the level of deterioration in a patient’s sense of smell has now been developed. While the more obvious Parkinson’s symptoms, such as tremors and muscular rigidity, appear at a later stage. Dysfunction in the sense of smell can be detected months or even years earlier, thanks to newly developed sniffing test. This opens the way for treatment that may delay the progression of this presently incurable disease.                ...

A NEW WAY OF LIFE

-
                                                        The world today is faced with the overwhelming problem of the MATERIALISTIC LIFE. So many people are concerned that their lives have no purpose or direction in them. Scientific discoveries over the past few years have done little to ease the burden of millions whose lives are far from what they should be. The cause of the suffering and pain pervading human life today is its total absorption in the material way of life. The soul of man is pushed into the background as if it did not exist.       This absorption with life as it is today has brought nothing but despair and disappointment. Those who have pursued the material way of life to it...
