Is key to face differences in ‘junk’ DNA?
Researchers have discovered regions of noncoding DNA that may play major roles in developing the shapes of faces.
The Striped Eel Catfish, Plotosus lineatus, is widespread in coastal waters of the Indo-Pacific Region. The only catfish found in coral reefs, it also lives in estuaries, tide pools and open coasts. Juveniles form dense ball-shaped schools of about 100 fish. Adults are solitary or occur in smaller groups of around 20 and are known to hide under ledges during the day.

Red-tailed Hawk (Buteo jamaicensis)
One of our most widespread raptor species, the Red-tailed Hawk is also easily the most variable. Color morphs range from very pale with predominantly white bellies, to very dark all over. The red tail of the adult is the one constant across all morphs. Well, almost all - the dark Alaska-breeding Harlan’s Red-tailed Hawk has a gray tail (and is sometimes considered a separate species). Immature birds lack the red tail, and have pale eyes that gradually darken as they age, becoming a rich brown (as in this bird) when fully mature at 3-4 years old.
Individuals may live to be 20 years old or more. The Red-tail is the hawk most people are most familiar with, because its preference for edge habitats, such as roadsides, makes it conspicuous and frequently seen. They are extremely adaptable, occurring in nearly all of North America’s habitats except tundra. The bird in this photo may have been “mantling” - drooping its wings to protect a prey item from being stolen by competition, a common behavior among this and other raptors.

Rabbs’ fringe-limbed treefrog (Ecnomiohyla rabborum) is a large species of frog originally found in the forest canopies of central Panama. Only discovered in 2005, the species is thought to be extinct in the wild; only one specimen, a male at the Atlanta Botanical Garden, survives.

Blue whales are the largest animals ever known to have lived on Earth. The largest specimen on record weighed 210 tons and was 98 feet long. There are less than 12,000 of the endangered species left in the ocean as it has been hunted to the brink of extinction.

Titanium Rainbow Quartz Cluster. To achieve this brilliant display of color, the Arkansas Quartz Crystals is treated with select minerals, such as titanium, etc. This is done via an electrostatic process whereby the crystals are put into a vacuum and charged opposite the select mineral. High Heat is applied. The select mineral is then put into the vacuum and it “clings” to the crystals. The crystals are then turned over and the process is repeated, so that all areas are covered. This treatment is a permanent and on the outside only.
A majestic rare albino whale shark graces the ocean
Sometimes, Nature puts on a show that leaves Man awestruck. And these spectacular displays by two denizens of the deep left all who saw them beguiled by their grace and beauty. Divers were stunned by the sight of a 33ft albino whale shark as it glided through the waters off the coast of Darwin, an island in the Galapagos group. (Full Story)
