Out of these 118 only some elements are connected with the human body. Although elements as such don’t make up the body it is the combined form that is molecules constitute the human …

DNA Decoding Sheds Light on Neanderthal Life

DNA decoding is a powerful technique. It is a molecular level investigation tool about the life. It has helped the life scientists to say with confidence that at the molecular level, all life is identical to 99.9%. The remaining 0.1 % is all which is responsible for the vivid diversity of life. According to one report, Neanderthals, our distant cousins, used natural drugs to alleviate the pain and diseases. 50000 years ago, they were depending on the natural cures.

Budgies in our homes

Many a times we thought of keeping pets at home. Our preference was always on keeping a dog but it is not practical with our present circumstances. Being two old persons, it is very difficult. It has to be regularly taken out for walks not doing which will be an injustice to the animal. More difficult is the situation when both persons have to go out for somedays. Where to keep it then?

Chemistry of Tanning

People in Asia and Africa where plenty of sunshine is available and weather is hot have a auburn or dark skin. This is because of production of melanin in the skin and making it look brown or dark.

Most people are not satisfied with whatever have God given to them. For example, the people in India want to look fair like …

Graphene: Size Zero Allotrope

Carbon is the atom on which the life on the earth is based. Though it is not a complicated element having only 6 atomic number, it ability to form compounds with hydrogen, oxygen, sulfur and host of other atoms and its ability for catenation makes it the most distinguished element for us. We owe our existence to it. Most of the macromolecules which are bodies are composed of contain carbon, hydrogen and oxygen. This simple element show another very surprising properties. One of them is the allotropy. Two allotrope are two different arrangements in which an element can exist. Till …

Microbes Rule Our World

There are trillions of microbes which inhabit an adult body. Looking at the sheer numbers, one may think that all these microbes are responsible for the ailments only. But this is not true. On the contrary, microbes are much more our friends than our enemies. Microbes run this world despite their infinitely small size. Their success lies in the sheer numbers and ability to adapt to the changing conditions. Following is the list of some species of the microbes that make our lives better: Bacillus thuringiensis: A common soil bacterium that is a natural pest-killer in gardens and on crops. …

Nature Works on Molecular Level

Human beings are trying to shrink the data storage space. In fact, technology is making exponential strides in this field. Only within the last decade, we have graduated from spooled data storage to blue ray DVD which can hold many layer of data. Not only it is matter of storage, but very fast retrieval of the data that is taking place. Look at Google Search, it fetches so many webpages within milli seconds. But still, the efforts are on to still go to more more and micro sizes. When we read, our imagination begins to conjure the physical attributes. For …
