Organ transplants save lives, but they come with challenges: every minute a healthy donated organ is on ice increases risk. And even if things go perfectly, rejection of the organ is still possible. Cardiothoracic surgeon Abbas Ardehali introduces cutting-edge medical advances in machine perfusion — a portable platform that keeps organs alive outside of the body — that could help put time back on the patient's side.
Hundreds of millions of people lack access to electricity in Sub-Saharan Africa, relying on highly polluting diesel and firewood for power and light.

After bringing her son to a summer camp for gender-nonconforming children, photographer Lindsay Morris launched a project to share the campers' stories with the world. One of them, Reed J. Williams, is now a powerful advocate for transgender youth.

Hundreds of millions of migrant workers travel within their countries to seek out means of survival — often leaving behind all they know for months or even years. Many face poverty and exploitation, and they need a robust social safety net to protect them, says migrant advocate and 2023 Audacious Project grantee Ashif Shaikh. He shares how his grassroots organization Migrants Resilience Collaborative is making life-changing benefits like social security and health care accessible to those who need them while also amplifying migrant voices — paving the way towards a world that supports the workers actually building it. (This ambitious idea is a part of the Audacious Project, TED's initiative to inspire and fund global change.)
We're still in the dark about what 95 percent of our universe is made of — and the standard model for understanding particle physics has hit a limit. What's the next step forward? Particle physicist Alex Keshavarzi digs into the first results of the Muon g-2 experiment at Fermilab in Chicago, which found compelling evidence of new particles or forces existing in our universe — a finding that could act as a window into the subatomic world and deepen our understanding of the fabric of reality.
Women are routinely underestimated, overlooked, interrupted, talked over or mistaken for someone more junior at the workplace. Author Mary Ann Sieghart calls this the "authority gap" — all the ways women are (still) taken less seriously than men, despite proven competence and expertise. She explains how we can close this pernicious gap and why everyone wins when we do so.

(This conversation is hosted by TED curator Cloe Shasha Brooks.)

Ocean waters are constantly on the move, traveling far distances in complex currents that regulate Earth's climate and weather patterns. How might climate change impact this critical system? Oceanographer Susan Lozier dives into the data, which suggests that ocean overturning is slowing down as waters gradually warm — and takes us on board the international effort to track these changes and set us on the right course while we still have time.
