In the waters off the Hawaiian Islands, rates of calcification were measured in the deepest coral colonies.
In the waters off the Hawaiian Islands, rates of calcification were measured in the deepest coral colonies and reported recently in a study led by a University of Hawai'i at Manoa oceanographer.
"In addition to being from the deepest coral analyzed, these are by far the lowest calcification rates ever measured for healthy, light-dependent corals in their natural habitat," said Kahng."These rates are 20-40 times slower than observed in shallow water corals."dominate the coral community in deep, low-light zones throughout the Indo-Pacific region.
Because Hawai'i has such clear water, coral reef ecosystems extend offshore to extreme depths, with specialized light-dependent coral communities as deep as 500 feet.

Ancient metal cauldrons give us clues about what people ate in the Bronze Age -- ScienceDailyArchaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period (3700--2900 BCE).

Neuroscientists successfully test theory that forgetting is actually a form of learning -- ScienceDailyNeuroscientists report the first results from experimental tests designed to explore the idea that 'forgetting' might not be a bad thing, and that it may represent a form of learning -- and outline results that support their core idea. Seemingly lost memories can be retrieved and updated by environmental cues, which means this research has implications for a range of diseases such as Alzheimer's.

With advances in in vitro models, group proposes refined legal definition of an embryo -- ScienceDailyThanks to continuous advances in human stem cell research, studies that make use of embryo models are progressing quickly. This research offers both a scientific and ethical alternative to the use of embryos resulting from fertilized human eggs, and the appropriate ethical guidelines have been developed in parallel with the advances being made. A group of biologists and ethicists suggest additions to the current ethical framework that refine thinking about human embryology using embryo models to maximize benefits to society.
