A look at 'super agers' and the science behind longer, sharper lives

For thousands of years, humans have tried to avoid growing old. Billions are spent every year on potions and procedures to make us look younger, feel younger and think younger. It's a hugely profitable, but ultimately fruitless hunt. But science has started to zero in on some proven techniques. Horizons moderator William Brangham explores that with Dr. Eric Topol and Dr. Sandra Weintraub. PBS News is supported by - https://www.pbs.org/newshour/about/funders. Hosted on Acast.

As the impact from the war in Iran grinds on, Americans are feeling it at the gas station. Evangelists for clean energy say the oil shock is an opportunity to embrace the transition to renewable power like wind and solar. With energy prices on the rise, Horizons moderator William Brangham explores if Americans are open to a new way of powering our world with Bill McKibben and Jigar Shah.

Americans are anxious about their jobs and whether artificial intelligence is coming for them. Some prominent voices call it catastrophic, others say it's hype. The data, so far, is somewhere in between and deeply contested. Geoff Bennett spoke with Josh Tyrangiel about his recent story for The Atlantic, "America Isn't Ready for What AI Will Do to Jobs."

The four-astronaut crew of NASA's Artemis II flew to the far side of the moon and set a record for the farthest distance from Earth traveled by any human. Monday's seven-hour lunar flyby was the most anticipated part of the mission. Amna Nawaz discussed the historic achievement with science correspondent Miles O'Brien.

We tend to think of cancer as a disease that mainly affects older people, but an increasing number of diagnoses are happening amongst the young. What is behind this alarming rise? And can anything be done to prevent it? Horizons moderator William Brangham explores those questions and more with Laura Behnke, Dr. Veda Giri and Dr. Shanthi Sivendran.

A day after liftoff, Artemis II is now well on its way. Four astronauts are on a ten-day voyage around the moon and back, traveling deeper into space than any human has ever before. For more about what's happening now and what comes next, Amna Nawaz spoke with science correspondent Miles O'Brien. PBS News is supported by - https://www.pbs.org/newshour/about/funders.

For the first time in more than 50 years, the United States is sending astronauts back toward the moon. NASA launched Artemis II from the Kennedy Space Center in Florida, sending a crew of four astronauts on a 10-day voyage. If all goes as planned, they will travel farther into space than any humans before them. Miles O'Brien was there for the launch and joined Amna Nawaz to discuss the mission.

The Trump administration has rolled back support for many forms of clean energy. One exception is nuclear power. The president wants to quadruple U.S. nuclear capacity by 2050, and a new generation of advanced reactors in development could signal the dawn of a new nuclear age.
