Researchers isolate a pest gene that can help fight pesticide contamination in environment.

Persistent use of chemical pesticides to increase crop productivity has led to their accumulation in soil, water and even food. Now a group of researchers from Pune have isolated an enzyme from a pest and found that it can be used to clean up pesticide residues from food and environment.

Researchers from Savitribai Phule Pune University have isolated a gene that produces a highly efficient enzyme (Glutathione –S-transferase or GST) from bollworm, a pest. This enzyme, they say, can be used for removing pesticides from food and environment.

Superbugs can not only render antibiotics useless but lead to prolonged suffering and death in humans. Focus on better sanitation and public awareness is the need of the hour.

There is a huge dearth of cleanliness in India--open defecation is rampant; garbage management in most cities is in shambles; toxic hospital and industrial wastes and sewage are allowed to drain into water sources and food products are laced with chemicals.

However, we still seem to be oblivious to the much more dangerous consequence of this incessant poisoning of our water, soil and environment and its impact on health and survival. For lurking behind the filth are superbugs or antibiotic resistant bacteria.

Superbugs, killers in disguise!

Unregulated salt production near Sambhar lake is not just causing health problems among salt workers, it is also depleting groundwater and ruining the ecosystem of the wetland.

The fields are silvery white with raw salt crusts in the vicinity of Nawa, a small town on the northwestern banks of Sambhar lake, India’s largest inland lake. Nawa lies about 90 kilometres east of Jaipur. Also an extensive saline wetland and a Ramsar site, the blinding white salt flats stretch as far as one can see. The place is a key wintering area for thousands of pink flamingos and other migratory birds from northern Asia and Siberia. Surrounded by the Aravalli on all sides, the lake straddles Nagaur, Sikar, Ajmer and Jaipur districts of Rajasthan.
