Phys.org / Ocean fronts revealed as key players in Earth's carbon cycle

Narrow bands of ocean covering just over one-third of the world's seas are responsible for absorbing nearly three-quarters of the carbon dioxide that oceans pull from the atmosphere, new research shows. The study, published ...

Phys.org / Climate-risk scores guide major decisions, but underlying science is rarely open

When families decide where to buy a home, when cities approve new development, or when governments decide where to invest billions in resilience, they increasingly turn to climate-risk scores for guidance.

Phys.org / Cuttlefish use polarized light to create a dramatic mating display invisible to humans

Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal courting rituals. Less obvious ...
