A blank spot on a digital map can signal much more than a gap in data -- it can mean something is being intentionally hidden. Sharing the remarkable discovery of massive alleged detention camps in Xinjiang, China, Pulitzer Prize-winning journalist Alison Killing shows how governments can obscure human rights abuses by limiting journalist access on the ground -- and calls for more reliable open-source data (like satellite and social media imagery) to shine a light on the world's darkest places.

The world needs clean power, but decarbonization calls for a massive increase in the mining and extraction of minerals like lithium, graphite and cobalt. Environmental peacemaking expert Olivia Lazard sheds light on the scramble for these precious mineral resources -- and how the countries that control their supply chains (including China and Russia) could find themselves at the center of the new global stage. Learn why Lazard thinks planetary security depends on our ability to de-escalate resource competition and avoid the same mistakes that led to the climate crisis.

How does a nation reconcile when its identity is at odds with its policies? Ali Noorani traces the arc of the US immigration debate to show a safer and more compassionate way forward, highlighting why centering human dignity creates lasting bonds and healthier communities.

From nourishing our foods to storing massive amounts of carbon, soil is teeming with diverse microbial life that could slow global warming.

SpaceX's Starship launch vehicle has the potential to explore the solar system in a bold, new -- and supersized -- way. Planetary scientist Jennifer Heldmann talks about how reusable, large-scale spacecraft like Starship could help humanity achieve its next galactic leaps and usher in a new era of space exploration, from investigating the solar system's many ocean worlds to launching bigger telescopes that can see deeper into the universe.

Our lives depend on curbing climate change, but so many priorities seem to be in competition. What's the most urgent thing humanity can do right now? Social entrepreneur James Irungu Mwangi tells us why Africa could be the ideal home for scaling the latest and most ambitious climate technologies -- including in places like Kenya's Hell's Gate National Park, which could become part of what he calls the "Great Carbon Valley."

Today, there are many ways to conceive a child, thanks to assisted reproductive technologies like IVF and egg-freezing.
