Mains:
General Studies Paper 3 (Science & Technology / Environment / Health): "Science and Technology- developments and their applications and effects in everyday life"; "Awareness in the fields of Bio-technology"; "Conservation, environmental pollution and degradation" (impact of urbanization on ecosystems); "Disaster Management" (Health disasters/epidemics).
Key Highlights from the News
The 'ലണ്ടൻ അണ്ടർഗ്രൗണ്ട് കൊതുക്' (London Underground mosquito) did not evolve recently, a new DNA study reveals.
This mosquito originated thousands of years ago in West Asia (for example, in ancient Egypt).
Its ancient adaptations were \"pre-programmed\" for urban life, which later helped them establish colonies in subways.
This finding will help in understanding the spread of the West Nile virus.
