The deeper these octopuses live, the wartier their skin

Deep beneath the ocean's surface, surprisingly cute pink octopuses creep along the seafloor. Some of them have super warty skin, and some are smooth. Scientists weren't sure if these octopuses were even members of the same species, and they didn't know how to explain the differences in the animals' looks. But a new study shows that the deeper in the ocean the octopuses live, the bumpier their skin and the smaller their bodies.

Dual approach needed to save sinking cities and bleaching corals

Local conservation can boost the climate resilience of coastal ecosystems, species and cities and buy them time in their fight against sea-level rise, ocean acidification and warming temperatures, a study by scientists suggests. In all but extreme situations, these interventions significantly buffer the impacts of climate change and can buy sinking cities and bleaching corals time to adapt until the beneficial impacts of global emissions reductions kick in.

Machine learning helps plant science turn over a new leaf

Researchers have developed machine-learning algorithms that teach a computer system to analyze three-dimensional shapes of the branches and leaves of a plant. The study may help scientists better quantify how plants respond to climate change, genetic mutations or other factors.

New method gives first global picture of mutual predictability of atmosphere and ocean

Scientists have carried out a novel statistical analysis to determine for the first time a global picture of how the ocean helps predict the low-level atmosphere and vice versa. They observed ubiquitous influence of the ocean on the atmosphere in the extratropics, which has been difficult to demonstrate with dynamic models of atmospheric and oceanic circulation.
