For the first time, scientists have seen stony coral cells engulf dinoflagellates - single-celled, photosynthetic algae that are crucial for keeping coral alive
The researchers used a cell line called IVB5, which contains endoderm-like cells cultured from the stony coral,
Acropora tenuis
Around 40% of coral cells incorporated the algae in around 30 minutes and remained healthy for one month
The research is a step towards understanding the partnership between coral and dinoflagellates and could shed light on how coral bleaching occurs ....

Caltech: Magnetism Drives Metals to Insulators in New Experiment


Share
Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual materials go from acting like a chunk of gold to acting like a piece of wood as temperatures are lowered. Physicists have developed theories to explain this so-called metal–insulator transition, but the mechanisms behind the transitions are not always clear. ....

An illustration of two domains (blue and orange) divided by a domain wall (white area) in a material. The magnetic order is designated with organized arrows (electron spins) while the colors represent two different domains (but the same magnetic order). In the material pictured here, the domain walls are conductive and the domains are insulating.
