Artificial Leaf

Research to harness the clean and renewable energy of the Sun is going on around the Globe. Artificial leaf made by a professor and his team at MIT is a step in this direction. Nature is so complex that even the structure of a leaf which is a basic unit for converting absorbed Carbon dioxide (CO2 ) and water (H2O) into glucose is beyond full comprehension. Human beings try to break down every phenomena in nature into smaller manageable parts and understand it and then integrate the results. This is due to the evolution of our brain in such a… Read More »Artificial Leaf

Changing Colors of Leaves

Nature is a great chemist. It is playing with chemical pigments to present vivid colors. Even a single leaf is a piece of art. There are many classes of pigments present inside it but their amount and times of breakdown and synthesis decides the resultant color. The different colors are on display during autumn season. The leaves begin to look less and less green. They can take yellow, orange and red hues depending upon the ratios of the amounts of different pigments present in the leaves. Most important pigment in the leaves is the chlorophyll. It is this pigment which… Read More »Changing Colors of Leaves

Our Body is a Wonder Machine

Photosynthesis is the process by which plants make two essential things on which the very survival of animals is hinged. These are namely a sugar called Glucose and oxygen. In the beginning oxygen was a poison to many microbes. But since it was a question of survive or perish, slowly they adapted to respiration using oxygen. Those which could not change receded to great depth where oxygen cannot reach. Glucose is a like a charged battery which stores energy. Where does this energy come from? Obviously it is the Sun on which the life on the Earth is based upon.… Read More »Our Body is a Wonder Machine

Thinking Brain hogs more Energy

Though human brain accounts for less than 2% by weight, it is a energy hog. About 20% of all the energy used by our body is consumed by our brain. This is because brain cells are always at work. Even while you sleep, much of your brain is busy managing your body’s physiological and biochemical operations. Brain uses neurotransmitters for sending and receiving the commands and messages to the organs of the body. Like the head honcho of a company, it is always thinking to run the body trouble free and thus constantly consumes more energy. Not only that, the… Read More »Thinking Brain hogs more Energy
