For over three decades, Liu Li Ping has been racing against stroke. She led the landmark “CHANCE” clinical trial—the first from China published in The New England Journal of Medicine—reducing patients’ 90-day recurrence rate from 11.7% to 8.2%, and further down to 6% in subsequent studies, rewriting global treatment guidelines and saving millions of lives. Her team developed domestically produced thrombolytic drugs, ending reliance on expensive imports, and combined them with AI imaging systems to cut treatment times from 120 minutes to just 20, extending the treatment window from 4.5 hours to 24. For Liu, victory in medicine is never a finish line—it is the courage to leave the comfort zone, to move from saving one life to transforming an entire field, and to keep going where the road runs long.

- 17:33Are We Heading Into a Cyber "Cuban Missile Crisis" | Kathleen Kennedy Townsend | TEDxPacific AvenueDrawing from her unique perspective as RFK's eldest child and President JFK's niece, Kathleen Kennedy Townsend parallels the dangers she witnessed firsthand—Senate Rackets Committee hearings, Mob threats, and the Cuban Missile Crisis—with today's critical software vulnerabilities.Our enemies can disable power grids, telecommunications, banking, hospitals, water systems, and breach military secrets through unsafe software. Yet unlike every other consumer product, software lacks safety requirements. We blame victims, forcing them to buy extra security while leaving Americans vulnerable to hackers, scammers, and foreign adversaries.With minimal regulation and weak consumer protections, our digital infrastructure remains dangerously exposed. Kathleen illuminates these hidden threats and champions the urgent need for secure software standards to protect "We The People" from 21st-century dangers that echo the threats her father fought 60 years ago. Kathleen Kennedy Townsend: KKT was Maryland's first woman's Lt Governor, and has served as Managing Director of Rock Creek, one of the largest women owned asset management firms in the country. She founded a Center on Retirement Security at Georgetown University and just recently served as Senior Advisor to the Secretary of the Navy where she focused on shipyard and shipbuilding, particularly submarines and aircraft carriers.
