What Does A Hydrogen Economy Actually Need?
Hydrogen can store energy and replace fossil fuels in some industrial processes, but only if production, transport and storage all work at once. Each of those is a separate unsolved problem.

Why Is Space Debris Becoming A Problem?
Orbits are filling with defunct satellites and fragments. At orbital speeds, even a small piece is destructive, and the debris can keep generating more debris.

What Does Battery Recycling Actually Involve?
Recycling lithium-ion batteries is possible and increasingly necessary, but it is closer to chemical processing than to ordinary waste sorting.

What Has The Search For Life On Mars Found?
Mars has not yielded life, but it has yielded something almost as interesting: detailed evidence that it was once habitable, and harder questions about how to look properly.

Why Are Insect Populations Declining?
Reported insect declines have alarmed researchers, but the evidence is uneven. Habitat loss and intensive agriculture are the most consistently supported drivers.

Why Are Volcanic Eruptions Still Hard To Forecast?
Volcanoes often give warning, but the warning does not reliably say when or how big. Forecasting is limited by how little we can see of the plumbing beneath a volcano.
