This is part of its efforts to popularize science to the General Public and Students who are pursuing science as their career. TNSF attempt to focus on students on higher science as everyone knows that learning of science at college within the curriculum is not enough to acquire holistic knowledge of science at the appropriate time.

What will be the effect of the sea level rise on coastal regions like Chennai ?
