The movement of carbon between the atmosphere, oceans and continents — or carbon cycle — regulates Earth’s climate, with the ocean playing a major role in carbon sequestration. A new study finds that the shape and depth of the ocean floor explain up to 50% of the changes in depth at which carbon has been …

Splash a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the droplets of water seem to roll and float, hovering above the surface. The temperature at which this phenomenon, called the Leidenfrost effect, occurs is predictable, usually happening above 230 degrees Celsius. A …

New data on over 1,500 trees across nearly 1,000 sites shows that an existing theory of how individuals within a species will respond to a changing climate might not be true. The data, in the form of tree rings from an aridland pine, contradicts the… ​New data on over 1,500 trees across nearly 1,000 sites …
