The promise of the cone snail

 
They might be known better for their exquisitely patterned shells, but cone snails are also some of the planet's most lethally venomous animals. The slow and seemingly innocuous marine snail is in fact an efficient predator. It hints fast-moving fish with its venom-coated harpoon, releasing sophisticated toxins that stun, paralyse and finally kill the prey.
Focusing on their venom, and its possible medical uses, leading science institutes and a university have come together for a major collaborative study of the snail. These institutions include the Tata institute of Fundamental Research(TIFR) in Mumbai, the Indian Instiute of Sceince(IISc) and the National Centre for Biological Sceince, both in Bangalore, and Annamalao University in Chidambaram, Tamil Nadu.

Quarries can help solve water scarcity

 
Amid mounting public concern over the series of accidental deaths at abandoned granite quarries across the State, the Kozhikode based Centre for Water Resources Development and Management (CWRDM) has come up with a proposal for the scientific development of such sites to resolve water scarcity in parched areas. Dozens of people have lost their lives in the abandoned quarries, forcing the Government to spend huge sums on fencing the sites. Last month, two school children were drowned in a flooded quarry at Kallumala, near P.T.P.Nagar, in Thiruvananthapuram. A recent study conducted by Kamalam Joseph and T.Valsan of the CWRDM recommended the steps to tap the quarries for a variety of uses by the local people.

Swaminathan panel moots SAZ status for Kuttanad

 
The M.S. Swaminathan Commission, which has been touring the Kuttanad wetlands in Alappuzha district since March 11 to formulate a special action plan for the region, has mooted promotion of Kuttanad as a Special Agricultural Zone (SAZ) on the lines of the Special Economic Zone. The Commission,  said its case study of Kuttanad indicated the need for the Central Government to promote SAZs in areas where agriculture, both as a way of life and as a means to income, should be preserved, by blending traditional wisdom and modern technology. Kuttanad is an ideal candidate for such a zone since ``the conservation and enhancement'' of paddy farming systems in the area is in the interests of both the State and the country. The team had suggested that the State Government focus on a few `urgent tasks' before the onset of the southwest monsoon. These include repair and maintenance of the Thottapally spillway, deepening of the eastern and western side of the leading canal, strengthening the outer bund flanking the leading canal and repair and completion of the Alappuzha-Changanassery (AC) canal. ``The Commission has also suggested to organise rice festivals during the `Harithavarsham' being observed by the State Government. These will help restore the pride of the region in rice cultivation. Attention is also needed for sustainable fisheries in the rice-fish farming system and for establishment of fish sanctuaries, fish farms and cage-culturing units to arrest the rapidly declining diversity of the species,'' he said.
Farm tourism
The action plan calls for promotion of sustainable nature, health and farm tourism. Farm tourism, Dr. Swaminathan said, would be of significance in the coming days because Kuttanad was the only place in the world where paddy was cultivated below sea level. ``With several areas expected to go below the sea in another 100 years, there are a large number of lessons Kuttanad can offer to the world,'' he said. Formation of a Kuttanad Water Tourism Promotion Society for Health and Happiness and its members enforcing a code of conduct to prevent water pollution, promotion of fish integrated farming systems and coconut farming systemsare also part of the plan.
