Jekyll and Hyde corals tell different warming story

(Phys.org) —Like the rings of a tree trunk, Strontium-to-calcium ratios (Sr/Ca) in coral skeletons have been widely used to determine past ocean temperatures from yearly banded corals. However, scientists have now found ...

Stem cells use signal orientation to guide division, study shows

Cells in the body need to be acutely aware of their surroundings. A signal from one direction may cause a cell to react in a very different way than if it had come from another direction. Unfortunately for researchers, such ...

New evidence highlights threat to Caribbean coral reef growth

Coral reefs build their structures by both producing and accumulating calcium carbonate, and this is essential for the maintenance and continued vertical growth capacity of reefs. An international research team has discovered ...

Study: Odd biochemistry yields lethal bacterial protein

While working out the structure of a cell-killing protein produced by some strains of the bacterium Enterococcus faecalis, researchers stumbled on a bit of unusual biochemistry. They found that a single enzyme helps form ...
