India is no stranger to air pollution, with the capital, New Delhi, being identified as one of the most polluted cities in the world, several times. The harmful effects of this deteriorating air quality can be seen in the increasing number of patients with respiratory disorders. Now, a team of scientists have designed a novel gas sensor using MEMS technology that is compact, highly sensitive, consumes very little power and accurately detects gaseous pollutants like CO, CO2, NO2 & SO2.
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.
