Clean drinking water is an essential prerequisite for good health. In a country like India, where 21% of communicable diseases spread through unsafe water, and more than 500 children under the age of five die each day from diarrhoea, the accessibility to clean drinking water is paramount. Researchers from the CSIR-Indian Institute of Toxicology Research, have developed a frugal water purification system, Oneer, to help overcome our water woes.

The 28th of February every year is celebrated across the country as ‘National Science Day’ to commemorate the discovery of ‘Raman effect’ by Sir C V Raman. About 90 years ago, Sir Chandrasekhara Venkata Raman, had a ‘eureka moment’ when he discovered how light scattered when it travelled in a transparent medium. After two years, this discovery won India her first Nobel Prize in Physics, for a work that was carried out entirely in India.
