This week's episode of Walk The Talk hosts one of the icons of Science in general and Biology in particular, Prof. Eric Lander who is a mathematician by education but took up Biology owing the interest evoked by the challenges in mapping the human gene. He candidly discusses how scientific research has progressed since the discovery of penicillin and that every generation leaves a legacy for the future. He says how cancer and HIV have been triumphed over though not entirely. He comments on how teaching is his passion and his research takes a back seat there. He hopes the Indian government furthers the funding to all kinds of scientific research and how science will not be bogged down by politics.
