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. ...

How much memory does our brain have?
|
view preview
While it's hard to calculate the memory capacity of the human brain, some estimates have put the number closer to 2.5 petabytes. But this is a great rough comparison.

Dental hygiene and the rainforest
|
view preview
Chewing sticks are used by many people instead of toothbrushes. The neem tree grows in many Asian, African, and Middle Eastern countries. Indigenous people in these areas know that chewing neem twigs is good for their teeth. The epidermal tissues contain chemicals that kill bacteria and reduce inflammation. The study of how indigenous (native) plants are used by different cultures is known as ethnobotany.

Preserved Baby Dinosaur!
|
view preview
It’s a pretty rare event to find complete fossils in good condition. After millions of years any number of things could happen to destroy fossils before they are discovered and documented by scientists, if the animal even fossilizes at all. Finding well preserved baby animals is particularly hard, since they are more likely to have gotten trampled or eaten after their death. Phillip Currie from the University of Alberta has recently uncovered a juvenile Chasmosaurus belli that was so complete and intact, he was actually able to speculate about the cause of death. Chasmosaurus belli is commonly found in British Columbia, Canada. It is a relative of the triceratops and has the familiar ornamental frill. Up to this point, all of the skeletons h ...

When spiders and trees collide
|
view preview
An unexpected side-effect of the 2010 flooding in parts of Sindh, Pakistan, was that millions of spiders climbed up into the trees to escape the rising flood waters; because of the scale of the flooding and the fact that the water took so long to recede, many trees became cocooned in spiders webs. People in the area had never seen this phenomenon before, but they also reported that there were less mosquitos than they would have expected, given the amount of standing water that was left. Not being bitten by mosquitoes was one small blessing for people that had lost everything in the floods. ...

Meeting of the waters

A pink Amazon river dolphin on the warm side of the "Meeting of the Waters." This is where the sandy Amazon River meets the dark waters of the Rio Negro in Manaus, Brazil. A strong density gradient contributes to their visible separation, as well as a significant temperature difference - the Amazon flows at around 22°C, while the Rio Negro is around 28°C.

Are the laws of physics the same everywhere on Earth?
|
view preview
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 ...

Why do men have bigger noses than women?
|
view preview
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.

Bipolar Vitamin C

It is extremely essential, that it is your guardian angel in times of stress and need, maintaining your relaxed pain-free state, while keeping your internal pluming up an going.. I like to call it the secondary police of the cell, after the primary cell cycle genes, that is. Not only does it go around making sure all compounds are receiving and exchanging electrons, but it is also among the military forces of the cell. It stands loyal to the cell when it is being invaded. When the cell's economy is no longer stable, mischievous backstabbers- bacteria and viruses or even toxins- love to take action and bring the cell city down, and that happens when there is a lack of electrons circulating, which is when Vitamin C military forces are cut bac ...

A fish that spits
|
view preview
Besides what we probably have seen while watching The Little Mermaid - fish singing and playing instruments, Finding Nemo, Shark Tale - whale being cleaned at a whale wash! , or even Spongebob Square pants - making hamburgers that is, have you ever seen or heard of a spitting fish? Well, I have not, until today.. Apparently, the archerfish from the family Toxotidea, literally "spit" to catch their prey. It is like a frog, but upgraded, in the sense that it catches insects and land based prey without a weapon, or a physical means. It just teleports its prey from above water, into the water by knocking it out via shooting water droplets. The missile strength of the water droplet is created and altered based on how far and how big their prey is ...
