How sugar affects the brain | Nicole Avena
When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine -- an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation. (Directed by STK Films, narrated by Michelle Snow, music by Michael Dow.) Stay tuned after the talk to hear our host Shoshana and biochemist Jessie Inchauspé dive into the importance of blood sugar awareness.
Racism has a cost for everyone | Heather McGhee
Racism makes our economy worse -- and not just in ways that harm people of color, says public policy expert Heather C. McGhee. From her research and travels across the US, McGhee shares startling insights into how racism fuels bad policymaking and drains our economic potential -- and offers a crucial rethink on what we can do to create a more prosperous nation for all. "Our fates are linked," she says. "It costs us so much to remain divided." After the talk, Shoshana sits down with Dr Aletha Maybank -- physician, Chief Health Equity Officer, and Senior Vice President of the American Medical Association -- to discuss how our neighborhoods impact our health.
How technology has changed what it's like to be deaf | Rebecca Knill
"Complete silence is very addictive," says Rebecca Knill, a writer who has cochlear implants that enable her to hear. In this funny, insightful talk, she explores the evolution of assistive listening technology, the outdated way people still respond to deafness and how we can shift our cultural understanding of ability to build a more inclusive world. "Technology has come so far," Knill says. "Our mindset just needs to catch up." After the talk hear from former TED speaker and palliative care physician Dr. BJ Miller in conversation with our host Shoshana on how his own disability has informed the way he cares for patients.
The breakthrough science of mRNA medicine | Melissa J. Moore
The secret behind medicine that uses messenger RNA (or mRNA) is that it "teaches" our bodies how to fight diseases on our own, leading to groundbreaking treatments for COVID-19 and, potentially one day, cancer, the flu and other ailments that have haunted humanity for millennia. RNA researcher Melissa J. Moore -- Moderna's chief scientific officer and one of the many people responsible for the rapid creation and deployment of their COVID-19 vaccine -- takes us down to the molecular level, unraveling how mRNA helps our bodies' proteins maintain health, prevent disease and correct errors in our genetic code. "We have entered an entirely new era of medicine," Moore says. Stay tuned after the talk to hear from the hosts of the popular podcast Unbiased Science, Dr. Jessica Steier and Dr. Andrea Love, in conversation with our host Shoshana on what they think the end of the pandemic could actually look like.
