It’s one of the most elusive superstars of the northern wilderness: the wolverine.

Nicknamed “the devil bear” for its fierce disposition, the wolverine is known to hunt moose and even tangle with grizzlies. Yet despite its hunting abilities, this member of the weasel family, closely related to river otters and minks, is only about the size of a cocker spaniel.

Getting a photograph of a wolverine was a mixture of luck and perseverance for photographer Peter Mather, who spent a month trying to capture an image of one. While driving down a remote highway in the Arctic’s northern Yukon, Mather spotted ravens circling overhead. When he stopped to investigate, he discovered a dead caribou surrounded by wolf tracks. He set up a camera trap, but when he returned a week later, he was surprised to find wolverine tracks by the carcass instead. The animal had been feeding on the caribou, which lay exposed on a riverbank.

One week later, when Mather came back to check his camera, he found that the river had flooded and frozen over, trapping the caribou underneath. —> Read More Here

On William Blake’s “Newton”


Between 1795 and 1805, the mystic poet, painter and printmaker William Blake produced a print that he entitled “Newton” (Figure 1). Just like the mythological figure Urizen, that to Blake portrayed law and reason in his piece “The Ancient of Days” (Figure 2), Blake’s Newton holds a compass. To Blake, this compass represented an instrument that clips the wings of imagination. Blake was a strong opponent to some of the aspects of the movement of the Enlightenment and its attempts to explain nature and all phenomena within it. In his view, Newton and the empiricist philosophers Francis Bacon and John Locke all conspired “to unweave the rainbow.” You’ll notice that in the print “Newton,” the scroll on which Newton draws his diagrams appears to emanate from Newton’s mouth. Newton himself is so absorbed in his diagrams that he seems to be blind to the beautifully complex rock behind him, which probably symbolizes the creative, artistic world. Blake went so far as to declare:

“Art is the tree of life.

Science is the tree of death.”

Somewhat similar sentiments were expressed by Blake’s contemporary, the young poet John Keats, who wrote:

“Philosophy will clip an Angel’s wings

European multicenter harmonization study shows anaplastic lymphoma kinase immunohistochemistry testing comparable to, if not better than, fluorescence in situ hybridization testing

Sixteen institutions across Europe collaborated together to show for the first time that a semi-quantitative anaplastic lymphoma kinase protein expression test, immunohistochemistry, is reliable amongst several laboratories and reviewers when test methodology and result interpretation are strictly standardized and the scoring pathologists are appropriately trained on the test. —> Read More Here
