These images are part of a series of remarkable patterns that bacteria form when grown in a petri dish. The colony structures form as adaptive responses to laboratory-imposed stresses that mimic hostile environments faced in nature. (via)
No, the image above does not some show some collection of freshly genetically designed hypercarrots in various colors of the rainbow. This is the spectrum of colors carrots used to have – and in some regions of the world you can still find white, yellow, red and purple carrots. In most countries however, carrots tend to be orange nowadays. Why is that?
They’re orange for entirely political reasons: in the 17th century, Dutch growers cultivated orange carrots as a tribute to William of Orange – who led the the struggle for Dutch independence – and the color stuck. A thousand years of yellow, white and purple carrot history, was wiped out in a generation.
Although some scholars doubt if orange carrots even existed prior to the 16th century, they now form the basis of most commercial cultivators around the world. Presumably crosses between Eastern (purple), Western (white, red) and perhaps wild carrots led to the formation of the orange rooted carrot sub species. Turkey is often cited as the original birthplace of the hybrids (or mutations) of the two groups.
Whatever the origins, the Long Orange Dutch carrot, first described in writing in 1721, is the forebear of the orange Horn carrot varieties so abundant nowadays. The Horn Carrot derives from the Netherlands town of Hoorn in the neighborhood of which it was presumably bred. All our modern, western carrots ultimately descend from these varieties. Hypernature avant la lettre.
North Island Giant Moa - now known by the binomial Dinornis novaezealandiae. This was the largest of the Giant Moas, and lived at the same time as the first New Zealanders. A large man would have been barely taller than the legs of this terrifyingly strong and fast bird.

“An experimental, arrowhead-shaped aircraft that could reach blistering speeds of 13,000 mph above the Pacific Ocean is set to blast off Wednesday from Vandenberg Air Force Base, northwest of Santa Barbara,” W.J. Hennigan reports. “To give you an idea of how fast that is: an aircraft at that speed would zip from Los Angeles to New York in less than 12 minutes.”
