Extra dimensions of space—the idea that we are immersed in hyperspace—may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still--but ultimately hit a dead end. Modern research has advanced the subject in ways he couldn’t have imagined. John Hockenberry joins Brian Greene, Lawrence Krauss, and other leading thinkers on a visual tour through wondrous spatial realms that may lie beyond the ones we experience.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

The Accelerating the Adoption of Agroforestry Project currently works with 24 community groups with a total of 600 members in Kericho and Kisumu counties in Kenya. 144 lead-farmers were trained in self-selected and context-specific climate-smart practices, including agroforestry, horticulture, coffee farming, poultry keeping and livestock keeping. Through farmer to farmer extension, the project reaches thousands of households in the project area and beyond.

Bola Ahmed Tinubu's political biography is one of the most audacious power accumulation stories in African democratic history.

This is the story of that journey and what his presidency has done to Nigeria and to Nigerians from the moment he took power on May 29, 2023, to June 2026.

This is episode 16 of Power & Plunder, a documentary series chronicling every head of state Nigeria has had since independence on October 1, 1960.
