    Your Words May Predict Your Future Mental Health

    Your Words May Predict Your Future Mental Health

    Can the way you speak and write today predict your future mental state, even the onset of psychosis? In this fascinating talk, neuroscientist Mariano Sigman reflects on ancient Greece and the origins of introspection to investigate how our words hint at our inner lives and details a word-mapping algorithm that could predict the development of schizophrenia. "We may be seeing in the future a very different form of mental health," Sigman says, "based on objective, quantitative and automated analysis of the words we write, of the words we say."

    What Your Breath Could Reveal about Your Health

    What Your Breath Could Reveal about Your Health

    There's no better way to stop a disease than to catch and treat it early, before symptoms occur. That's the whole point of medical screening techniques like radiography, MRIs and blood tests. But there's one medium with overlooked potential for medical analysis: your breath. Technologist Julian Burschka shares the latest in the science of breath analysis -- the screening of the volatile organic compounds in your exhaled breath -- and how it could be used as a powerful tool to detect, predict and ultimately prevent disease.
