Frozen methane bubbles
|
view preview
Abraham Lake lies in the foothills of the Canadian Rockies. The view is breathtaking, especially during wintertime, when methane bubbles freeze right underneath the surface, creating eerie cloud-like formations. The phenomenon has a simple explanation: plants on the lake bed release methane bubbles, which freeze once they’re close enough to the surface. In springtime, when the ice starts to thaw, the gas is released into the atmosphere.

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. ...

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.

Crows are impressive
|
view preview
Nature always finds a way. Natural materials can be hard to come by in large cities, so the very industrious crows living in Tokyo, Japan occasionally resort to stealing clothes hangers from people's apartments to carefully assemble them into nests.

Birds with purple crowns
|
view preview
These beautiful birds are called purple-crowned fairy wrens, endemic to northern Australia. The picture was taken by ornithologists (bird banders) studying the birds as part of population monitoring in Australia. The way they are holding them is called "photographer's grip" which gently secures the legs while keeping the rest of the bird free. Handling time is generally very short.

Bipolar Vitamin C

view preview
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 ...

Are the laws of physics the same everywhere on Earth?

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 ...

Are silent farts worse?
|
view preview
On average, they are, because they tend to contain more sulphur, which is what gives farts their unpleasant smell. Loud farts, on the other hand, tend to contain more nitrogen, hydrogen and carbon dioxide, which are all odourless gases.

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 ...
