Although Solar energy has been often hailed as a green source of energy, shortcomings in conventional silicon based solar cells and the environmental damage caused during mining and manufacturing of such cells raises questions on the green nature of the energy. In a breakthrough, scientists have developed organic solar cells, developed from indigenously developed discotic liquid crystal, that could provide an alternative.
New research reveals that a unique Indian skink species arrived on the subcontinent by rafting across the ocean from Southeast Asia millions of years ago, a journey made possible by fluctuating sea levels.
