New design is based on quantum dots. A new type of semiconductor laser that can be easily modified to create light over a range of different colours has been created by researchers in the US. The device is based on tiny particles called colloidal quantum dots (CQDs) that emit different colours of light according to their size – rather than their chemical composition. - Weird ocean current may create coral refuges
Global warming is expected to have devastating effects on coral reefs, but recent research points to a few exceptions. Warming in the equatorial Pacific may actually create refuges for corals around a handful of islands, even as it bleaches, or kills, corals elsewhere, suggests new research that predicts increased upwelling of cold, nutrient-rich water in these places. ![](http://feeds.feedburner.com/~r/pcsolutionsarea/~4/TJbWIz72wQY?utm_source=feedburner&utm_medium=email) |
