The biological clock is an internal and independent mechanism that dictates daily rhythm, thus enabling an organism to gauge daily and seasonal signals and live in sync with the rhythm of nature, ...

The reefs scattered throughout the tropics arose only after algae took up full-time residence in coral cells, supplying corals with abundant food and enabling them to build extensive shallow-water ...

During a two-year survey of soft corals in the Florida Keys, scientists identified three species of octocorals that have survived heat waves. While the coral animal itself may be heat tolerant, ...

Coral reefs form as a partnership between sea anemone-like polyps and photosynthetic algae that provides nutrients for the former and safe, well-lit shelter for the latter. But this alliance might not ...

The physical interactions between coral and algal cells as they combine to form a symbiotic relationship have been observed for the first time. Within minutes of being introduced, coral cells had ...

A marine biologist from Brazil is studying the microscopic zooxanthellae algae that live within coral to see to what extent it can help reefs bounce back from bleaching. Due to climate change, coral ...

Scientists have seen stony coral cells engulf dinoflagellates - single-celled, photosynthetic algae that are crucial for keeping coral alive. The researchers cultured endoderm-like cells from the ...

Antler coral can host different types of algae, sometimes resulting in differences in color. Thomas Kline / Design Pics via Getty Images As global temperatures spike to new highs and heat waves pass ...

Time is running out for coral reefs as the climate gets hotter. So scientists are searching the globe for corals that are better at enduring heat. Now, new research shows how those "super corals" can ...

Some corals can swap out the algae that live inside their tissues for different strains that are more heat tolerant – and these coral species have a better chance of surviving global climate change in ...
