Red Tide Causes Glow-In-The-Dark Blue Waves On San Diego Beaches (VIDEOS) Who knew red tide caused blue waves? San Diego's beaches are captivating many with an eerie nighttime phenomenon. It seems that "red tide" is causing bioluminescent glow-in-the-dark waves in the area, a sight that's almost too eerie to believe.
But you can see it for yourself in the videos below. According to the Los Angeles Times, an unusual algae bloom has turned the surf red by day, and provided this effect at night. The electric blue glow is caused by an algae bloom commonly referred to as a “red tide.” More specifically, the color is caused by a chemical reaction that results from the movement of the algae. The event is mildly toxic, GrindTV reported, but isn't really harmful to humans beyond making a swim a bit uncomfortable. How much longer the blue surf will last is unknown.

Things That Kill More People Than Sharks. It might be Shark Week at Discovery channel, but hot dogs & high school football kill more people than sharks. A good reminder that a fear of sharks is irrational. Check out the list of 20 things that kill more people than sharks every year here. Among them….hippos, lightening, tornadoes….oh, and hotdogs (which target CHILDREN!). Source: buzzfeed. Nature by numbers. The theory behind this movie.
We can find interactive sites on the internet (like this) to draw points, move them, and check how the structure becomes updated in real time. In fact, if we have a series of random dots scattered in the plane, the best way of finding the correct Voronoi Telesación for this set is using the Delaunay triangulation. And in fact, this is precisely the idea shown on the animation: first the Delaunay Triangulation and then, subsequently, the Voronoi Tessellation. But to draw a correct Delaunay Triangulation is necessary to meet the so-called “Delaunay Condition”. This means that: a network of triangles could be considered Delaunay Triangulation if all circumcircles of all triangles of the network are “empty”. Notice that actually, given a certain number of points in the plane there is no single way to draw triangles, there are many.
But only one possible triangulation meets this condition. You see that in the graph below, extracted from Wikipedia: Luminous beings from the depths of the sea. Ever Wonder What a Hermit Crab Looks Like Inside the Shell? Welcome to whalesong.net. Leaf-like sea slug feeds on light - Technology & Science. A green sea slug found off North America's east coast not only looks like a leaf, but can also make food out of sunlight, just like a plant.
U.S. researchers have found that the sea slug Elysia chlorotica can photosynthesize, using energy from light to convert carbon dioxide into sugars. "If you shine light on these slugs, they fix carbon dioxide and make oxygen just like a plant," Sidney Pierce of the University of South Florida told CBC Radio's Quirks & Quarks. Pierce reported his findings Jan. 7 at the annual meeting of the Society for Integrative and Comparative Biology, and has submitted his research to the journal Symbiosis. The slugs look just like a leaf, green and about three centimetres long, and are found off the east coast of North America from Nova Scotia to Florida. They acquire the ability to photosynthesize by eating algae and incorporating the plants' tiny chlorophyll-containing structures, called chloroplasts, into their own cells. Gene transfer a revelation.

By Thomas Morton Photos by Jake Burghart I’m not one of those guys who corners folks at parties to rant at them about biodiesel or calls people “fucking idiots” for being skeptical about global warming. But I should also point out that I’m not one of those Andrew Dice Clay “Fuck the whales” types either. The problem with all the bravado on both sides of the ecology debate is that nobody really knows what they’re talking about. Trying to form opinions on climate change, overpopulation, and peak oil hinges on ginormous leaps of faith based around tiny statistical deviances that even the scientists studying them have a hard time understanding.
Well, I have just such a thing. In the middle of the 90s, Charles Moore was sailing his racing catamaran back to California from Hawaii and decided on a lark to cut through the center of the North Pacific Gyre. The problem with plastic is, unless you hammer it with enough pressure to make a diamond, it never fully disintegrates. D a n c i n g f i s h - lembeh strait.
