Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the possibility that our reality contains extra dimensions

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story   

Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge is to find them

This is a New Scientist special package about shock results that have upended cosmology. What do they mean for our models of the universe, and what are the alternative explanations?

Putting silicate rocks from mine waste on fields could improve crops and limit global warming, but some researchers question where all that rock is going to come from
