A rat king is a rare phenomenon arising in rats where a number of rats become intertwined at the tails. The museum Mauritianum in Altenburg (Thuringia) shows the largest well-known mummified rat king, which was found in 1828, consisting of 32 rats. They were seen as extremely bad omens, particularly associated with plagues. Such events also occurred, since rat kings arise only if too many rats exist, for example the Black Death, which is spread by rat fleas.
The helmet urchin (Colobocentrotus atratus) is found in Hawaii it is known as “kaupali” which translates as “cliff-clinging.”

The Mathematics of Beauty
The Fibonacci Sequence is a sequence of numbers where each number is the sum of the previous two—i.e., 0, 1, 1, 2, 3, 5, 8, 13, 21, 34…and so on to infinity. The ratio of one number to the next is approximately 1.61803, which is called “phi”, or the Golden Ratio. It’s not a magical mathematical equation of the universe, but it definitely reflects natural, aesthetically beautiful patterns. The ratio been used as the ideal proportion standard by artists and architects throughout history, and it’s also found in nature because it’s one of the most efficient way to pack things together. The human body can mostly be divided up in terms of the golden ratio, with one nose, two eyes, three segments to each limb, five fingers on each hand, and our measurements and proportions also reflect the ratio, especially the proportions of the human face—the width of the nose, position of the eyes, length of the chin. Our attraction to another person increases if their body and features are symmetrical and proportional, since we perceive them to be healthier, and so the Golden Ratio appears to be connected with humans ideals of beauty. It’s worth noting, however, that although the ratio can create a beautiful face, it can’t create a beautiful mind.
The Alnwick Poison Garden is pretty much what you’d think it is: a garden full of plants that can kill you (among many other things). Some of the plants are so dangerous that they have to be kept behind bars. [x]
The Coldest Place in the World
By NASA Goddard
What is the coldest place in the world? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night — colder than the previous recorded low temperature.
Scientists at the National Snow and Ice Data Center made the discovery while analyzing the most detailed global surface temperature maps to date, developed with data from remote sensing satellites including the MODIS sensor on NASA’s Aqua satellite, and the TIRS sensor on Landsat 8, a joint project of NASA and the U.S. Geological Survey (USGS).
The researchers analyzed 32 years of data from several satellite instruments that have mapped Antarctica’s surface temperature. Near a high ridge that runs from Dome Arugs to Dome Fuji, the scientists found clusters of pockets that have plummeted to record low temperatures dozens of times. The lowest temperature the satellites detected — minus 136 F (minus 93.2 C), on Aug. 10, 2010.
The new record is several degrees colder than the previous low of minus 128.6 F (minus 89.2 C), set in 1983 at the Russian Vostok Research Station in East Antarctica. The coldest permanently inhabited place on Earth is northeastern Siberia, where temperatures dropped to a bone-chilling 90 degrees below zero F (minus 67.8 C) in the towns of Verkhoyansk (in 1892) and Oimekon (in 1933).

Extra-terrestrial volcanism is every bit as stellar as its sounds. The Earth puts on its fair share of spectacular eruptions — but it’s Earth’s distant cousins who win the awards. Lava-scarred Venus has more volcanoes than any other planet we know; Olympus Mons, a treble Everest soaring above Mars’ Northern Hemisphere, is the largest active peak in the solar system; while Saturn’s frozen moon, Enceladus, where cryovolcanoes shoot towering streams of water through a crust of solid ice, must surely rank as the strangest.

Phobias may be memories passed down in genes from ancestors
Memories may be passed down through generations in DNA in a process that may be the underlying cause of phobias
Memories can be passed down to later generations through genetic switches that allow offspring to inherit the experience of their ancestors, according to new research that may explain how phobias can develop. Scientists have long assumed that memories and learned experiences built up during a lifetime must be passed on by teaching later generations or through personal experience. However, new research has shown that it is possible for some information to be inherited biologically through chemical changes that occur in DNA. Researchers at the Emory University School of Medicine, in Atlanta, found that mice can pass on learned information about traumatic or stressful experiences – in this case a fear of the smell of cherry blossom – to subsequent generations. The results may help to explain why people suffer from seemingly irrational phobias – it may be based on the inherited experiences of their ancestors.
