The blue planet’s toxic new colours
1. Tissue slurry — Ontario, Canada This man-made lake in Terrace Bay, Ontario, Canada, is more than 500 metres long. It’s an aeration pond, part of the waste-treatment system at a factory that produces pulp for Kimberly-Clark tissues. “The treated water is returned to its source — often a river,” says Fair. Each yellow cone is an “agitator” that aerates and churns the liquid, assisting its breakdown. According to Worldwatch Institute figures, if recycled paper was used instead, 64 per cent less energy would be needed.and churns the liquid, assisting its breakdown.

2. Fertiliser — Louisiana, US This emerald-tinted lake near Geismar, Louisiana, includes gypsum, uranium and radium. These chemicals result from manufacturing phosphorous fertiliser and are dumped into this impoundment to solidify. The world’s supplies of phosphates are dwindling and most are located in the US, China and Morocco. Unlike oil, however, there is no known renewable alternative for making fertiliser. “You think the resource crisis is in oil?” says Fair. “Think again.”
3. Spilled oil — Gulf of Mexico, US Fair captured this shot over the BP Deepwater Horizon spill at the Macondo well in June 2010, when 750m litres of oil leaked into the Gulf. “The stuff that was coming out of that well was all different colours,” says Fair. “We think of crude oil as being black — it’s all kinds of different colours and consistencies.” The bright red is the crude on the surface, reflecting light. The less viscous oil below the surface is purple-brown.
4. Liquid sulphur — Alberta, Canada At Fort McMurray in Alberta, Canada, a blood-red vein of liquid sulphur is pumped on to a bed of solidified yellow sulphur. The element is one of the major by-products of tar-sand upgrading and there is now an abundance of stocks globally. With prices low, producer Syncrude isn’t selling — it’s storing it in giant pyramids. Liquid sulphur, at around 200°C (its melting point is 115°C), is pumped into fenced-off compounds and left to harden.
5. Aluminium sludge — Louisiana, US This slurry pit is where the solid and liquid by-products of aluminium manufacture are separated. The process involves refining bauxite ore, which produces alumina. The waste includes bauxite impurities, heavy metals and sodium hydroxide (one of the chemicals used during processing). Fair estimates that the red-brown sludge has a pH of about 13, “meaning if you touch it, it burns the skin off”.
6. Fertiliser slurry — Louisiana, US This wintry-looking scene is a mix of lead, ammonia, mercury and ethanol — by-products of phosphate fertiliser production. “It’s a giant lake of waste,” says Fair, who shot the image 80km west of New Orleans in 2005. Owned by Mosaic Fertilizers, the plant, called Uncle Sam, has violated the US Clean Water Act nine times. The slurry pit is less than 3km from the banks of the Mississippi.

Post reblogged from The Blog.. with 310 notes
It’s not news that sleep is tied to learning — even a 90-minute nap can significantly help boost your brain power — but if you want to cement new knowledge in your brain, recent sleep research demonstrates that a good night’s sleep shortly following your studies has a significant impact on your ability to retain information.
The study in question asked participants to memorize related word pairs (e.g., circus – clown) and unrelated word pairs (e.g., cactus – brick). Some participants learned the words at 9am, some at 9pm. The 9pm crowd went to sleep shortly after learning the words. The 9am crowd did not.
The results: Sleep made no difference when participants were asked to recall the related words, but when participants were asked to recall unrelated word pairs, the 9pm group — the group that slept right after learning — did significantly better. So where your brain already has a strong semantic roadmap for learning (as is the case with the related word pairs), sleep doesn’t have a major effect. Where it’s forming new connections, sleep makes all the difference.
Stick that in your mind pipe next time you need to do some serious cramming.

Bioluminescence in the Gippsland Lakes
Noctiluca scintillans doing what it does best in the Gippsland Lakes, a small chain of inland lakes in Victoria, Australia.
The events that transpired to make this happen are quite miraculous; firstly there was widespread fires in Victoria that burned pretty intensely for quite some time. Then, they were followed by intense flooding that inundated many areas of Gippsland amongst others. The basic effect was that floodwaters carried nutrient-rich soil and ash from the higher reaches into the Gippsland basin, leading to a eutrophic condition in which algae and bacteria can thrive.
This gave rise to a particularly prolific cyanobacteria getting a foothold, Synechococcus. Essentiallysmothering the lake in cellular life, it gave an opportunity for some pretty special creatures to breed prolifically given an abundant food source - Noctiluca scintillans, a bioluminescent Dinoflagellate.
And so, you end up with photographs like this. A once-in-a-lifetime occurrence, captured for all to share.

Adam Savage dipping his fingers into a pot of molten lead. Immediately prior to submerging his fingers in the lead, he wet them with water, which will form a thin protective layer of water vapor on contact with the lead, which was heated to 850 degrees Fahrenheit. This is known as the Leidenfrost effect.

r721:
Animated simulation of gravitational lensing caused by a Schwarzschild black hole going past a background galaxy. A secondary image of the galaxy can be seen within the black hole Einstein ring on the opposite direction of that of the galaxy. The secondary image grows (remaining within the Einstein ring) as the primary image approaches the black hole. The surface brightness of the two images remain constant, but their angular size vary, hence producing an amplification of the galaxy luminosity as seen from a distant observer. The maximum amplification occurs when the background galaxy (or in the present case a bright part of it) is exactly behind the black hole.

Neon Anatomical Art, by Jessica Lloyd-Jones. From the artist:
Blown glass human organs encapsulate inert gases displaying different colours under the influence of an electric current. The human anatomy is a complex, biological system in which energy plays a vital role. Brain Wave conveys neurological processing activity as a kinetic and sensory, physical phenomena through its display of moving electric plasma. Optic Nerve shows a similar effect, more akin to the blood vessels of the eye and with a front ‘lens’ magnifiying the movement and the intensity of light. Heart is a representation of the human heart illuminated by still red neon gas. Electric Lungs is a more technically intricate structure with xenon gas spreading through its passage ways, communicating our human unawareness of the trace gases we inhale in our breathable atmosphere.

“This image depicts the interaction of nine plane waves—expanding sets of ripples, like the waves you would see if you simultaneously dropped nine stones into a still pond. The pattern is called a quasicrystal because it has an ordered structure, but the structure never repeats exactly. The waves produced by dropping four or more stones into a pond always form a quasicrystal.”

Dazzling Photographs of Earth From Above
Satellite images of mountains, glaciers, deserts and other landscapes become incredible works of art
1. Van Gogh From Space (July 13, 2005)
The green and blue swirls of the Baltic Sea surrounding the Swedish island Gotland look like they could have been painted by Vincent van Gogh, but they are the work of microscopic marine plants called phytoplankton. When ocean currents bring an abundance of nutrients to the surface, the population of tiny plants proliferates into big, colorful blooms.
2. Lake Eyre (August 5, 2006)
The ghostly face is part of southern Australia’s Lake Eyre. The desert lake remains dry most of the year, filling during the rainy season. When the lake is completely full—which has only happened three times in the past 150 years—it is the largest lake on the continent.
3. Spilled Paint (February 10, 2003)
The various hues of this abstract scene represent the different landscapes present in Dasht-e Kavir, or the Great Salt Desert, of northern Iran. The sparsely populated desert is named after its many salt marshes (“kavir” means salt marsh in Persian). The Great Salt Desert is also home to dry streambeds, plateaus and mud flats, covering almost 30,000 square miles of the Iranian Plateau.
4. Icelandic Tiger (October 21, 1999)
Nature often inspires art, but sometimes it is art. For almost 40 years, the Landsat satellites have been snapping images of earth that look more like they belong on the walls of a modern art museum than stored in a scientific archive. The U.S. Geological Survey, which manages the satellite program with NASA, is sharing the beauty of these photos in its new “Earth as Art” exhibit on display at the Library of Congress through May 31, 2012.
Everyone at USGS who works with Landsat data has a favorite photo, and that led to the idea of gathering a collection of favorites to share with the public, says Ronald Beck, a USGS public information specialist who has worked with the Landsat Program for 37 years. Beck’s favorite in the new exhibit, the third installment of “Earth as Art,” is Icelandic Tiger. The “tiger” is part of Iceland’s northern coast, and its mouth is the fjord called Eyjafjorour, meaning “Island Fjord.” The name refers to the small island the tiger is about to eat.
