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.

Drinking calcium-rich milk strengthens your bones -- but it's not the only thing you can do for a strong and healthy skeleton. Dr. Jen Gunter digs deep into the three layers of bone to explain why they weaken as we age and shares what you can do to maintain a healthy frame for years to come. Want to hear more from Dr. Gunter? Check out her podcast Body Stuff, from the TED Audio Collective.

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.

Microglia are the primary immune cells in the central nervous system. In the brain, they play central roles in proper development and function, as well as dysfunction and disease. In her first talk, Dr. Beth Stevens provides an overview of the many ways microglia cells operate, and how they can both harm and protect the brain. Fairly recent advances in the study of microglia through imaging have allowed researchers to identify different microglia states and study their dynamic roles at different stages of development. In her second second talk, Dr. Stevens dives deeper into the mechanisms that allow microglia to shape the network of connections between neurons in the brain. She provides an introduction to the role of microglia in synaptic pruning, the process of eliminating extra synapses in healthy developing brains. She then goes on to explain how the reactivation of this process affects aging and diseased brains.

Where you live: It impacts your health as much as diet and genes do, but it's not part of your medical records. At TEDMED, Bill Davenhall shows how overlooked government geo-data (from local heart-attack rates to toxic dumpsite info) can mesh with mobile GPS apps to keep doctors in the loop. Call it "geo-medicine."

At TEDMED, Eric Dishman makes a bold argument: The US health care system is like computing circa 1959, tethered to big, unwieldy central systems: hospitals, doctors, nursing homes. As our aging population booms, it's imperative, he says, to create personal, networked, home-based health care for all.

Surprising, but true: More women now die of heart disease than men, yet cardiovascular research has long focused on men. Pioneering doctor C. Noel Bairey Merz shares what we know and don't know about women's heart health -- including the remarkably different symptoms women present during a heart attack (and why they're often missed).
