To detect diseases earlier, let’s speak bacteria’s secret language | Fatima AlZahra’a Alatraktchi

    Because lyme is such a tricky infection to detect, perhaps this could help with earlier diagnosis. LYME must be treated almost immediately after infected, so this could be ground breaking!

    This says that bacteria release signals before they seriously attack, and this women has tests that uncover bacteria’s early signalling before the culture is positive. Her reaction is to treat early with antibiotics. Antibiotics results in microbiome responding with more virulent strains. Perhaps there is an alternative to antibiotics. Maybe intermittent fasting- not eating for 12- 16- 20 ? hours per day, keeps the bacterial microbiome from fighting, or becoming virulent by making them thin out on a daily basis- instead of them reproducing more by making their food constantly available in high amounts. Could this explain why under-eating has always been associated with longevity?

This speaker took on gerrymandering in her state — and won! #TEDTalks

You don’t need political power to make real change, says activist Katie Fahey. She tells the story of how she led a successful movement in Michigan to end gerrymandering — the practice of drawing district lines to favor one political party — and how it all started with a simple social media post.

What good is a vaccine people don’t trust? Immunologist and TED Fellow Kizzmekia Corbett co-developed the first COVID-19 vaccine to enter clinical trials — but she says making the vaccine was never the hardest part. The real obstacle is the gap between scientists and the people who have honest questions about the shots they’re being asked to take. She shares a refreshing approach for taking on vaccine inquisitiveness and ensuring that humanity is ready for the next pandemic. (Recorded at TED2026 on April 15, 2026)
