My latest read is Amitav Ghosh's science fiction thriller "The Calcutta Chromosome". I heard about this book while I was in college. I had never thought of Ghosh as a sci-fi writer. But the book dispelled all such notions. The book revolves around the idea that chromosomes may be used to transfer information from one individual to another. This is hardly a radical concept since this occurs during sexual reproduction where the embryo inherits a pair of chromosomes - one from its father and other from its mother. However the information swapped pertain to the organism's genome i.e. hereditary genetic data. The Calcutta chromosome is imagined to be a vector for carrying non-hereditary information such as one's "psyche" and it is transferred asexually. Think of it as similar to backing up one's personal data into another data repository which is in this case another individual. Ghosh thus offers a possible explanation for the Indian occult concept of transmigration of souls ("koodu vittu koodu maaral" in malayalam). I am not usually impressed by the English works of Indian writers. But this is definitely worth reading.
