Hot springs harbour microbial diversity
Posted on 28 Feb, 2018 08:31 PMMicroorganisms can be found in almost every habitat in the environment owing to their capacity to adapt and to survive. Some of them can withstand extremely hot environments such as natural hot springs. Studying such organisms can help in understanding not just why they are so hardy but may also yield new and useful chemicals.

Purify water safely
Posted on 17 Jan, 2018 09:49 AMThe use of ultraviolet lamps in water purifiers is common but the presence of mercury in these lamps could be potentially hazardous. Now a group of Indian scientists have developed a mercury-free ultraviolet lamp that can be used in water purifiers.

Plastic waste to decontaminate water
Posted on 15 Dec, 2017 07:36 PMRecycling is the only option to handle plastic waste at present. Now Indian scientists have found a new use for plastic waste--for decontamination of water.
