Values In Science

Nandita

Values are far more important in today’s age of science and technology, than they probably were at any precious time in human history. Science and technology touch every aspect of our lives.

Water Hyacinth

Befriending The Noxious Weed

Dipanjan Ghosh

It is blacklisted as a notorious aquatic weed in India and other tropical countries, and often designated as ‘Bengal terror’, ‘blue devil’, ‘invasive weed’, ‘noxious plant’, ‘plant pest’, ‘prohibited aquatic weed’ and so on. The target of such abusive nicknames, water hyacinth, is a dreaded waterweed often blamed for choking water bodies and creating problems for other aquatic plants and animal inhabitants. However, lately its role in environmental cleaning is being truly recognized.
