What is R136a1?
British astronomers have discovered the biggest star of the Universe and it has been named R136a1.It is a blue hyper giant star with an estimated 265 solar masses. The star also holds the record for the most luminous at 10, times the luminosity of the Sun. Like other hyper giant stars that sit above the Eddington limit, R136a1 has been shedding large portions of its own mass in violent outbursts. It is estimated that at its birth the star held 320 solar masses and has been losing 50 solar masses...

What are Aghoni & Bhogali?
'Aghoni', is a 'soak and eat variety' of rice that is fit to be consumed just by soaking it in normal water for 40 minutes without any boiling or steaming. This variety has been developed by the Regional Agricultural Research Station in Assam Agricultural University. There's no need to boil and the rice need only stay in the water for it to soak in the moisture. There are other varieties of this kind. Worth mention is Bhogali which is available in the count...
Which Planets are Jovian Planets?
The Gas Giants are known as Jovian Planets. The Gas giants of the solar system viz.Jupiter, Saturn, Uranus and Neptune are called Jovian Planets. The term is derived from "Jupiter". They are mostly surrounded by natural moons and rotate faster than the terrestrial planets....
What is a Maine Coon?
Maine Coon is a highly preferred breed of cat. The name is derived from North American state of Maine, in which it is the official state cat. Maine Coon has very distinctive physical features and is said to have descended from the pairings of local short-haired breeds brought overseas by English seafarers in United States....
What is a Seed Crystal ?
Tiny single crystals made to dissolve in a solution or melt from which larger crystals are drawn either by precipitation, centrifuging or drawing up from a melt. The seeds must have the same chemical composition and crystalline structure as that of the larger crystal. The practice is used in semi-conductor industries and making artificial single crystal gemstones like silicon, germanium, sapphire, diamond, zirconia and so on....
What is Ambergris?
Ambergris is used in manufacturing of the Perfumes. Its a waxy material which is produced in the sperm whale and pygmy sperm whale. It is formed in the rectum of the whale by indigestible parts of from animals on which it feeds. It is released normally when Whale di...
What is Arachnophobia?
Arachnophobia refers to fear of spiders. This phobia was exploited in a 1990 movie "Arachnophobia". The word is derived from the Greek 'arachne' (spider) and 'phobos' (fear) after the mythical Arachne, a maiden who was a skilled weaver, whom the goddess Athena turned into a spider on being challenged to a weaving contest....
What is the difference between CNG and LNG?
The major difference between Compressed Natural Gas (CNG) and Liquefied natural gas (LNG) is that the former is NOT liquefied. CNG involved compressing the natural gas to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 200–248 bar (2900–3600 psi), usually in cylindrical or spherical shapes. LNG is involves liquefying natural gas temporarily to liquid form, which is 1/600th the volume of natural gas in the...
What is a genome map?
Every organism whether an animal, a plant, a fungus, a bacterium, an Archean, a protist or a virus, has DNA. A stretch of DNA that codes for a type of protein or for an RNA chain which has a function in the body / organism is called a Gene. So, a Gene is the basic unit of heredity. One the sequence of genes on DNA is identified; it can be scientifically manipulated for different purposes.The aim of the genome projects is to determine the complete genome sequence of an organism.In human there are...
In which state of India occur most Cloud Bursts?
It’s a type of torrential rainfall accompanied by hail and thunder, usually observed in high altitude areas and occurs due to the formation of a low pressure area on the top of a mountain. The low pressure zone attracts clouds to the top of the mountain with great force. When they hit the peak, the moisture content is released in the form of rain. Most cloudburst occur in India in Himachal Pradesh....
What is a Buckey Ball?
Buckyball or fullerene is the newly found allotrope of carbon. Bucky ball is a carbon molecule structure (C60) shaped like a hollow sphere. It is composed of only carbon atoms and also known as buckminsterfullereneSpherical fullerenes are called buckey balls whereas cylindrical ones are called buckytubes. Harold Kroto, Richard Smalley, James Heath and Robert Curl discovered (C60) at Rice University. It was named after architect Richard Buckminster Fuller and discovered in 1985. Google recently...
How many Quite Zones are there in a Barcode?
Barcode is an optical machine-readable representation of data on certain products. It can be read by optical scanners called barcode readers. The code uses this sequence to represent numbers and other symbols. A barcode symbol typically consists of five parts: a quiet zone, a start character, data characters (including an optional check character), a stop character, and another quiet zo...
If Chemical Formula of Glucose and Fructose is same, then what is difference?
Mirror image is a concept from chemistry applied to organic materials. Glucose and Fructose molecules are mirror images of each other. Although it is possible to flip glucose and superimpose it over a fructose molecule, only in 2D (flat viewing) are they simil...
What is Burundanga?
This a a term used for a drug 'Scopolamine', also known as levo-duboisine, and hyoscine. It is used for committing crimes such as rape or to rob innocent victims. The drug is passed on to the victim through business cards, pamphlets or through tablets added to drinks. This is known as the 'dating drug'. It was also used in witchcraft and sorce...
What makes soaps Transparent?
The Transparent soaps are made of glycerin. They are partly soap and partly solvent. It is Sodium hydroxide (NaOH) that causes crystals to form in soap and makes them opaque. When it is dissolved in a solvent the crystals become so small that light passes from th...
What is the difference in Quarks and Gluons ?
For a long time we know that nucleons i.e. protons and neutrons are the subatomic particles. The scientists are going further deeper and find that there is yet another layer of matter particles inside the nucleons. These elementary particles are calld quarks. Several Quarks bind together and make Hadrons. The best known hadrons are Protons and Neutrons.Quarks are held together by a force which has been dubbed the chromo force. The Chromo force is represented by particles named gluons. Both Quarks...
What are Presure Altimeters and Radio Altimeters?
Altimeter is used for measuring altitudes. There are two basic types of altimeters viz. pressure altimeters and radio altimeters. Pressure altimeters are aneroid barometers calibrated to indicate altitude instead of pressure. It is based on the principle of drop of atmospheric pressure with gain of height. The capsules inside the altimeter casings expand as we go up. This expansion is magnified to move the indicator over the dial. The mean sea level pressure is 1013.2 millibars or 29.92 inches...
What is Madras Eye?
Madras eye is Conjunctivitis. It refers to the inflammation of the outermost covering of the eyeball and inner layer of eyelid. It can be caused by various agents like bacteria, virus, wind, smoke, pollen, radiation or chemical agents.
