It has long been known that distinctive blue flashes--a type of bioluminescence--that are visible at night in some marine environments are caused by tiny, unicellular plankton known as dinoflagellates. However, a new study has, for the first time, detailed the potential mechanism for this bioluminesence.

This fascinating video captures a glimpse of the weird and wonderful animals that live in the aphotoc zone. The aphotic zone (aphotic from Greek prefix ἀ- + φῶς "without light") is the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1% of sunlight penetrates. Consequently, bioluminescence is essentially the only light found in this zone. Most food comes from dead organisms sinking to the bottom of the lake or ocean from overlying waters.This fascinating video captures a glimpse of the weird and wonderful animals that live... more

Some 80 to 90 percent of undersea creatures make light -- and we know very little about how or why. Bioluminescence expert Edith Widder explores this glowing, sparkling, luminous world, sharing glorious images and insight into the unseen depths (and brights) of the ocean.Some 80 to 90 percent of undersea creatures make light -- and we know very little... more

It boggles the mind to consider just how many lights illuminate our city and residential streets, and though some places (such as New York) draw on the grid far more than others, it's a global conservation issue that needs to be addressed, stat.
Well, efforts are underway to green up the way that we keep our streets well-lit...but who knew that it could become such a figurative and literal exercise with the proposal of eye-catching, power grid free bioluminescent trees!It boggles the mind to consider just how many lights illuminate our city and... more
