שותף באופן ציבורי -"Coral on a chip" cracks coral mysteries
We know that human-induced environmental changes are responsible for coral bleaching, disease, and infertility. Loss of the world’s stony coral reefs – up to 30% in the next 30 years, according to some estimates – will mean loss of their services, including sequestering some 70–90 million tons of carbon each year and supporting enormous marine biodiversity. Yet despite many advances, we are still far from understanding the causes and processes contributing to the corals’ demise.
The tiny – often less than a millimeter in diameter – animals that build coral reefs create a thin layer of living tissue surrounding the calcium-based skeleton. These animals live in symbiosis with single-celled, photosynthetic algae that provide nutrients and oxygen in return for carbon dioxide and shelter. In order to understand what happens during bleaching, when this symbiosis is broken, we need to understand what happens to these organisms at the cellular and molecular levels under various conditions.
A team of scientists have created a system they call “coral on a chip". They hope to track the nutrient and carbon cycles of reef-building corals, as well as delving further into disease and bleaching processes.
