Excavator Wasp Encountered

I found heaps of moist sand in front of a building site. A fly came to the sand and began to excavate it with its legs, and then entered into the burrow and returned out in a minute to fly away. I presumed that it might be a wasp with its name connected to sand – Sand Wasp. I searched for ‘Sand wasp’ in search engine. The results showed its name as ‘Sand wasp’ only!

These sand wasps (Bambicini) prey upon other insects. The females excavate the sand and form nests. They bring preys into the nest for the developing larvae.

To my astonishment I had a close encounter with another sand wasp on the very night of the day of my reference to the search results! It came into my house and was being attracted towards the UV rays of the tube light. It had a whitish grey back and three orange ring-like first divisions on the dorsum of its abdomen, and the rest of the divisions were black, each one of them ending in a white ring at its ending part!

Wonder encounters with this wonder wasp!

Similarly Rhyming Chemical Names!


There are about four chemicals the names of which have to be spelt carefully while reading. They are Acrylamide, Acetalamide, Acetanilide and Acetazolamide! Each one of these is different from the other.

Acrylamide is used as a thickening agent, and in the dye manufacture. It is naturally found formed in starchy fried foods like potato chips, French fries, and bread. In over-fried items its content rises and can damage male reproductive glands, if consumed a lot. It is also found to be a cancer producing agent.

Acetalamide is a solvent that is used in the synthesis of organic compounds.

Acetanilide is now used as a stabilizer in varnishes and in the syntheses of dyes and camphor. In the past it was used as a fever reducing medicine (antipyretic). Later it was discontinued as it had toxic effects on liver and kidneys.

Acetazolamide is a well known medicine (Diamox). It is used as a diuretic and is also prescribed in diseases, Glaucoma and Epileptic seizures.

So, be aware of these wonder resemblances in chemical names!

A Reaction that makes Foods Tastier



Toasted bread will be tempting with its aroma and flavors, isn’t it? These aroma and flavors are released by the heat of the toaster as the bread browns. There is an underlying chemical reaction for this: an aminoacid and a reducing sugar present in the bread react with each other wonderfully here. This reaction is called ‘Maillard Reaction’. This wonder reaction contributes to our tasting a variety of delicious food items!

Duck Chicks Jump

I came across this interesting video clip of
BBC's Planet Earth while I was viewing a blog in the 'Blogs of Note' of Blogger.com. This is my first wonder video to present!

The Wonders in Lightning



Energy is the need of the hour. Electric energy has to be obtained from thermal, nuclear, hydro and wind energies. There is always a demand for it. Actually its demand itself is increasing day by day. Imagine that we have periodically one billion volts of electric energy. What could it be? It is nothing but the wonderful ‘Lightning electric energy.’ It is not yet tapped for our increasing needs. But we fear about it that we may lose our life when it strikes, and so, we hesitate to tap its energy.

Lightning Injuries:

The lightning inflicts injuries on the victim’s body at the sites of its entry and exit. Ulcers are formed there. The major injuries are by its mechanical energy that is produced by the rapidly expanding heated air.

Ball Lightning Wonder:

Another wonder in Nature associated with the thunderstorm is reported. In May 2003, when a thunderstorm was here, I and my family members noticed a bright ball. It was about the size of a small orange. It arrived with a cracking sound that alerted us to note it. It cruised smoothly along the inner walls of the house. We all followed it from room to room till it exited out near a window! We are not sure whether it went out through the window or disappeared near the window wall itself! All these happened within a minute. Later on we came to know about it in one of TV channel programs that it is a ‘Ball Lightning’!

Parade of Winter and Spring Flowers


Winter and the spring are enchanting to both animals and plants. Birds sing their songs. Plants grow in luxuriance. They are green all over, and their flowers bloom in beautiful colors. These all the exhibits of the seasons enchant all of us. Here are some of their images:

Twin Roses
Passion flowers open at early morning and close at forenoon as sunlight intensifies.

Can you identify these wild flowers of the meadows?

The Wonder Fuel for a Bumper Harvest

The rose plant in my garden usually flowers to its most in the cool Winter only. But now, after the Spring is over here, and at this start of Summer, I am able to get it bloom more than that it did in the winter! The machine (the rose plant) worked the wonder with the ‘wonder fuel’ – the Vermipost! I strewed only just 200 grams of the vermipost around the roots on the well turned red soil and watered. That’s all. I got a harvest of more than sixty roses at a bloom! That too within 10 days! It is a “wonder ‘post” that deserves posting here – the Vermipost!

The Lizard with Miraculous Feat



The
Hindu puranas inform about the divine incredible powers of Holy Sages, Rishis and Siddhars – like walking on the water or floating on water etc. I know an insect that swims or surfs (or rests) on water surface with its six legs – the ‘Water Strider’! Have you heard of a lizard doing this feat? Yes, it is the Basilisk Lizard. When a predator chases, it runs on water with its two legs for about fifteen meters and escape! It has specially modified hind legs as that of a frog – webbed feet. Running with four limbs is tiresome, and with two legs, as we human do, it is quicker and easier, it seems – that too on water surface! A wonder lizard, indeed!

Descendants find their 'Roots'


Migration of birds for feeding and breeding are well known. These birds return back to their living places with their off- springs. The butterflies also do such migration; but there is a difference. In the migrated place they breed and bring up their generation; but they do not return back –they die there itself. Their next generation only returns to their original living place – without any guidance either from them or from anybody else! How is this possible? Do their generation have the replica of their brain to guide or do the generation have the ‘instinct’ (formed out of their parents’ past memory and experience) passed down to them genetically? Can any Zoologist or Genetics Scientist explain this wonder behavior of butterflies?
