Adequate water most important for plant diversity
Study shows how rainfall and temperature affect variety of plants in major bio-geographic zones of India priyad posted 2 years 2 months ago

New Delhi, July 9 (India Science Wire): India has a total geographical area of nearly 329 million hectares. The climate varies from the north to the south and east to west. However, in spite of this diversity, little is known about how climate affects the diversity of plants that grow in a particular area.

Gold nanoparticles to remove lead from wastewater
A new technique makes use of minuscule particles of the yellow metal and their property to change colour in the presence of metal particles such as lead. arathi posted 3 years 11 months ago

Gold, the favourite metal of Indian women, is increasingly becoming popular among scientists as well, though for a different reason. A group of Indian researchers has used gold nanoparticles to develop a simple method to detect lead in wastewater.
