New study on India's four most medically important snakes—the spectacled cobra, Russell's viper, common krait, and saw-scaled viper—has revealed that a snake's age, or life stage, is the dominant factor determining the amount of venom it produces.

The Indian krait is undoubtedly the deadliest of all venomous snakes in the country, and possesses the most lethal concoction of poisons. In a study, a multi-institute research team, led by the Translational Health Science and Technology Institute (THSTI), Faridabad, have designed a synthetic antivenom with a nucleic acid aptamer which can diagnose Indian krait bites accurately and effectively.
