A ganzfeld experiment is a technique used in the field of parapsychology to test individuals for extrasensory perception (ESP). It uses homogeneous and unpatterned sensory stimulation to produce the ganzfeld effect, an effect similar to sensory deprivation.The ganzfeld effect has been utilized in many studies of the neuroscience of perception, not only parapsychology. The deprivation of patterned sensory input is said to be conducive to inwardly generated impressions.The technique was devised by Wolfgang Metzger in the 1930s as part of his investigation into the gestalt theory. ...

The vortex is a spherical field of force, or a magnetic disturbance. The vortex is 165 feet in diameter and sits half way above ground and half below. The disturbance, or vortex causes unexplainable changes in perception, causing naturally occurring visual and perceptual phenomena that has been caught on film many times. Within the spherical distortion, people stand at an angle. The disturbance alters your relative gravity, causing you to stand at an angle of varying degrees. It is not possible for someone to stand vertical inside the vortex. It will also make someone who is walking away, seem taller, or shorter depending on where you stand. Balls roll uphill, brooms stand straight up and down on their own, and chairs appear to be held up b ...

Often dealing with hot, sweaty climates, tigers have learned to enjoy water, using it as a way to cool off, capture prey and relax.

The transparent glass frog is found in Venezuela. It is made up of many specialized cells that have different functions. They form different parts of this organism, which are easy to see through its “glass” skin.

This is an albino redwood tree, with white needles instead of green because it's unable to produce chlorophyll. In order to survive, albino redwoods must join their roots to those of a normal redwood to obtain nutrients. Found in Henry Cowell Redwoods State Park and Humboldt Redwoods State Park in the US, there are only around 20 known albino redwoods in the world, and their exact whereabouts have been kept secret as protection.

The king ragworm is a skilled hunter found in the northern hemisphere. The worm, which can grow over 120 cm long, also uses chemical signals to judge the risk of predation in the area.

Men’s noses are 10% larger than female's.

Males generally have leaner muscles and need more oxygen for muscle growth and maintenance—and larger noses mean more oxygen can be breathed. A new study found that the difference in nose size between males and females of European descent starts showing in early puberty, when 95% of body weight gain in males comes from fat-free mass, compared to 85% in females.

This little guy on the left is the iron sulphide secreting scaly-foot gastropod. It's the only animal known to plate itself with metal and lives in a thermal vent deep in the ocean. But last year scientists found a pale, genetically identical version of the species (on the right) that doesn't secrete metal, leading scientists to question what the purpose of the armour really is.
