Chemical Exposure

You come into contact with chemicals every day. This is called chemical exposure. Although some chemical exposures are safe, others are not. A certain amount of a harmful chemical must enter your body to make you sick. Harmful chemicals can get into your body if you breathe, eat, or drink them or if they are absorbed through your skin. This booklet explains some links between chemicals and other harmful substances and their possible health eff ects. For more details click here.

Supercomputers used to Supercharge Antioxidants

The future of keeping ageing-related diseases at bay lies with the supercomputer according to scientists from the ARC Centre of Excellence for Free Radical Chemistry and Biotechnology at the University of Sydney.

The research, led by Professor Leo Radom from the University's School of Chemistry, and Dr Amir Karton, University of Western Australia, has used sophisticated quantum chemistry and powerful supercomputers to design improved antioxidants which will help stave off ageing-related diseases such as heart disease, cancer, diabetes, and Alzheimer's disease.

Researchers Identify Seventh and Eighth Bases of DNA

For decades, scientists have known that DNA consists of four basic units -- adenine, guanine, thymine and cytosine. Those four bases have been taught in science textbooks and have formed the basis of the growing knowledge regarding how genes code for life. Yet in recent history, scientists have expanded that list from four to six. 
Now, with a finding published online in the July 21, 2011, issue of the journal Science, researchers from the UNC School of Medicine have discovered the seventh and eighth bases of DNA. 

These last two bases – called 5-formylcytosine and 5 carboxylcytosine – are actually versions of cytosine that have been modified by Tet proteins, molecular entities thought to play a role in DNA demethylation and stem cell reprogramming. For more details click here.

Message from Bhagavath Geetha
  • Do not get over excited over happiness and do not get over depressed over sorrow.
  • Do not get over bonded with anyone and anybody because it can lead to problems and sorrow.
  • Never think that my duty is the topmost or lowermost. Every duty is respectful. The responsibility undertaken or given as per the position is the noblest duty.
  • Elevate yourselves, family, society and nation and never denigrate yourselves, family, society and nation.
  • We are our own closest relatives and if not properly utilised we will become our closest enemies.
  • There are possibilities of success and failure in any endeavour. One cannot assure success always.
  • Death is inevitable for everyone in this world. In any endeavour at the maximum an individual may die.
  • People may say good and also they may say bad. Approach them with stabilised mind.
  • Take anything after scientifically, logically and rationally analysing them.
  • Perform your duty, responsibility and accept the privileges eligible for you.
  • First change ourselves and then try to change others.
  • We are all instruments /tools in the hands of the nature for performing the duty. So do not think that I am doing the duty. Think that I am an instrument to do the duty.
  • Results of action may not be sweet always. Accept what ever may be the result.
  • Follow the path of great scholars who guided the world. Listen their messages.
  • Results and rewards will come and go but stick to your duty with devotion, dedication and sincerity.
