    How Climate Change Affects Your Mental Health

    How Climate Change Affects Your Mental Health

    "For all that's ever been said about climate change, we haven't heard nearly enough about the psychological impacts of living in a warming world," says science writer Britt Wray. In this quick talk, she explores how climate change is threatening our well-being -- mental, social and spiritual -- and offers a starting point for what we can do about it.

    How The Gut Microbes You're Born with Affect Your Lifelong Health

    How The Gut Microbes You're Born with Affect Your Lifelong Health

    Your lifelong health may have been decided the day you were born, says microbiome researcher Henna-Maria Uusitupa. In this fascinating talk, she shows how the gut microbes you acquire during birth and as an infant impact your health into adulthood -- and discusses new microbiome research that could help tackle problems like obesity and diabetes.

    Want To Grow Healthy Food? Start with Your Lawn

    The fruits and vegetables we buy from the grocery story have been bred to grow bigger and faster — but at the cost of flavor and nutrition, says John C. Trimble, co-founder of Foodscaping Utah. Instead of wasting precious water to maintain the grass in our yards, he suggests we "foodscape" them instead. Not only will our produce taste better, but they'll be grown as locally as possible.

    How Synthetic Biology Can Improve Our Health, Food And Materials

    How Synthetic Biology Can Improve Our Health, Food And Materials

    What if we could use biology to restore our balance with nature without giving up modern creature comforts? Advocating for a new kind of environmentalism, scientist and entrepreneur Emily Leproust rethinks modern sustainability at the molecular level, using synthetic biology to create green alternatives. From lab-developed insulin and disease-resistant bananas to airplanes made of super-strong spider silk, she explains how reading and writing DNA can lead to groundbreaking innovations in health, food and materials.

    Obesity Genetics: Health Consequences of Being Fat

    Obesity Genetics: Health Consequences of Being Fat

    Easy access to nutrients has contributed to the increase in obesity in the human population. But, what is obesity and why isn’t everybody fat? Dr. Stephen O’Rahilly provides a biomedical perspective of obesity, and evaluates which genes could potentially shift the balance towards obesity. As he explains, one becomes obese when the balance between energy intake and energy spent is shifted. Surprisingly, mutations that lead to obesity in humans aren’t in genes involved in metabolism and energy storage, but failure in satiety signals in the brain that result in people eating too much. The excess of energy intake over energy expenditure leads to obesity. What is the consequence of obesity in human health? Physically, obesity can result in lower mobility and sleeping disorders. But, in humans, the link between obesity and metabolic diseases isn’t straightforward. For example, not everyone that’s obese becomes insulin resistant. As O’Rahilly explains, the probability of an obese individual to have a metabolic disease is linked to the capacity of adipose tissue to store the extra fat. Mutations that decrease fat storage in adipose tissue increase the chance of metabolic diseases, like insulin resistance, even when the person is not obese.

    An Evolutionary Perspective on Human Health And Disease

    An Evolutionary Perspective on Human Health And Disease

    How does your genetic inheritance, culture and history influence your health? Biological anthropologist Lara Durgavich discusses the field of evolutionary medicine as a gateway to understanding the quirks of human biology -- including why a genetic mutation can sometimes have beneficial effects -- and emphasizes how unraveling your own evolutionary past could glean insights into your current and future health.
