Could pink prison cells calm prisoners down? This psychologist thinks so
|
view preview
Would someone feel more calm after seeing the colour blue? Or perhaps they would feel more aggressive after having seen the colour red? Swiss psychiatrist, Max Lüscher, had completed a study in the 20 th century that linked colour preference to your personality and your mental state. His belief was further hardwired after an experiment concluded that 151 out of 153 people were weaker after looking at the pink card, when compared to how strong they were when they had looked at the blue card. ...

Must watch, this ancient Turkish language is whistled
|
view preview
Turkish communities living in the mountains in the north east of the country use a remarkable whistling language to communicate. Around 10,000 people use the bird-like whistle, which researchers suggest is the first known form of language to use both sides of the brain. Whistlers usually speak Turkish when talking near each other, but switch to whistling when they want to convey a message over longer distances, which can be up to five kilometers. The whistling language has the same vocabulary and grammatical structure as Turkish, it’s just a different format. Scientists have previously assumed that all spoken language, written texts and sign language mainly utilize the left hemisphere, but this doesn't seem to be the case for the whistling l ...

150 thousand people are going to die today
|
view preview
It's true, and this estimate is the same for tomorrow, and the day after. This video explains the Years of Life Lost measurement - a measurement which takes into account the age at which deaths occur by giving greater weight to deaths at younger age and lower weight to deaths at older age (more information can be found here). The video neatly displays the leading causes of death in each country from 2013. According to statistics, Saudi Arabia really needs to chill out with its driving antics given that death by vehicle is the leading cause of early death there at 19 people per day! ...

Speedy bacteria
|
view preview
Bdellovibrio bacteriovorus is a bacterium that attacks other bacteria. It can charge its prey at speeds of up to 100 micrometers per second, comparable to a human running 600 kilometers per hour. It then bores into its hapless victim by spinning at 100 revolutions per second. Most bacteria aren't quite that fast, but they can move by whipping flagella or by spiraling through their environment. ...

The Myers-Briggs test might just be a phony afterall
|
view preview
Could the most widely used personality questionnaire simply be a farce? In case you don't know, the Myers-Briggs test is an assessment test believed by many to measure psychological preferences in how they perceive things and help them in making decisions. According to the Myers-Briggs test, there exist sixteen different types of personalities. This Myers Briggs Test has a series of questions that require your answers, which in turn determine the type of personality you have and provides you with general assumptions concerning how your personality type best suits you. Back in year-3 of my undergrad., I had to spend $20 to take the test for an assignment I had to write. While it was interesting to note how my personality could be read throug ...

Tricking your brain into thinking you're in a room full of sunlight
|
view preview
There’s an innovative new light technology that's trying to change the way people think about "artificial light." In Italian company called CoeLux has developed a new light source that recreates the look of sunlight through a skylight so well that it can trick both human brains and cameras. It’s a high tech LED skylight that’s designed to provide "sunlight" for interior spaces cut off from the outdoors. One of the main ideas behind it is that to create realistic sunlight, you can’t just simulate the sun… you need to recreate the atmosphere as well. The scientists who invented the light figured out how to use a thin coating of nanoparticles to accurately simulate sunlight through Earth’s atmosphere and the effect known as Rayleigh scattering ...

Here's why your hair will eventually turn gray
|
view preview
As soon as we're born, we're destined to age. Some of us age gracefully - we enjoy years of youthfulness - while others experience hair loss, wrinkles, and greying earlier than expected. Found in the core of each hair, a pigment known as melanin gives rise to a person's hair color. This universal pigment is also found in our skin and eyes, giving use our unique physical traits. Dark and light versions of melanin - eumelanin and phaeomelanin, respectively - combine in various combinations to create all natural hair colors. Melanin itself is the product of a specialized cell, the melanocyte, which is found in each hair follicle, from which the hair grows. As hair grows, the melanocyte injects melanin into the hair cells, which contain the s ...

You won't believe what this viper does to lure hungry birds
|
view preview
The rare Iranian spider-tailed viper ( Pseudocerastes urarachnoides) waggles a fake "spider" - actually a fleshy lure with leg-like scales at the tip of its tail - to tempt birds within striking distance. Until 2001, the viper was known only from a single misidentified specimen collected during a U.S. expedition to Iran in 1968. The weird structure on its tail was so unlike anything documented in other snakes that it was written off as a birth defect or an abnormal growth. While scientists had suspected its unique tail was used for luring prey, new observations of the dramatic bird captures now confirm this. The new study also revealed the viper starts growing its tail lure after birth, and that it isn’t complete until adulthood.

After a broken neck left him quadriplegic, Ian Burkhart was told he would never be able to use his hands. Now he can grasp a bottle and pick up a credit card by using a computer plugged directly into his brain. Special software is able to decode his thoughts and convert them into electrical signals in his hand, bypassing the damaged nerves in his spine. Now Ian has regained an amazing degree of control over his hand, each movement stimulated by his own thoughts. https://www.youtube.com/watch?v=0I_q_dFtPhU ...
