Computer models reveal how human-driven climate change will dramatically overhaul critical nutrient cycles in the ocean. In the Proceedings of the National Academy of Sciences, University of California, Irvine researchers report evidence that marine nutrient cycles – essential for sustaining ocean ecosystems – are changing in unexpected ways as the planet continues to warm.

Space belongs to no-one, yet many nations and private entities now plan to lay their claim on its resources. The use of space is poorly regulated by laws or enforceable regulations, which makes sustainable long-term use a risky endeavor. In a recent Frontiers in Space Technologies article, Nishith Mishra, Martina Elia Vitoloni – both researchers at McGill University – and Dr Joseph Pelton, dean emeritus at the International Space University and chairman at ACES Worldwide, shared their thoughts about how plans to exploit the ocean floors could impact the way resources from space are used and managed.
