People have a distance at which they are best able to judge depth. That distance, it turns out, is dictated by how long people understand their arms to be. Researchers showed this in the Journal of Neuroscience by tricking subjects with virtual reality into thinking their reach was longer than it really was. The result? Their accurate perception of depth via sight moved outward and touch became more sensitive. We need to reach for things, so a connection between arm length and our ability...

Unlike adults, children are able to keep information from their senses separate and may therefore perceive the visual world differently, according to research published today. Scientists at UCL (University College London) and Birkbeck, University of London have found that children younger than 12 do not combine different sensory information to make sense of the world as adults do. This does not only apply to combining different senses, such as vision and sound, but also to the different...

Watching 3D television under normal conditions is unlikely to be damaging to the human visual system, scientists from The Vision Centre say. Commenting on possible health risks raised by some experts with the advent of 3D television, Professor Colin Clifford of The Vision Centre and The University of Sydney, an authority on how the brain interprets the visual signals from the eyes, says it is very unlikely that 3DTV could cause any long-term harm, provided people only watched it for a few...

Hammerhead sharks are some of the Ocean's most distinctive residents. 'Everyone wants to understand why they have this strange head shape,' says Michelle McComb from Florida Atlantic University. One possible reason is the shark's vision. 'Perhaps their visual field has been enhanced by their weird head shape,' says McComb, giving the sharks excellent stereovision and depth perception. However, according to McComb, there were two schools of thought on this theory. In 1942, G. Walls speculated...

By Hughes, Gordon Of all of the movements lucky enough to have been caught in the tangles of Alfred Barr's spider-web chart of modern art (Fig. 1), only one, Orphism-Guillaume Apollinaire's misbegotten term and attempt to unite the post-Cubist abstraction of Robert Delaunay, Marcel Duchamp, Fernand Lger, and Francis Picabia-goes nowhere.1 That the diagrammatic arrow leading from Cubism to Orphism ends in what Barr sees as the sole cul-de-sac in twentieth-century art is surprising given that...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
