biological sciences tell us the facts


Time Is Too Short For Myth and Superstition


Why not seek out Darwinism and evolution when you get that urge to finally think of your own mortality and the meaning of life?

Chrysopelea paradisi is in the air


The Paradise Tree Snake




Paradise tree snake or Paradise flying snakeChrysopelea paradisi, is a species of snake found in southeastern Asia. It can, like all species of its genus Chrysopelea, glide by stretching the body into a flattened strip using its ribs. It is mostly found in moist forests and can cover a horizontal distance of about 100 metres in a glide from the top of a tree. Slow motion photography shows an undulation of the snake's body in flight while the head remains relatively stable, suggesting controlled flight. They are mildly venomous with rear fangs and also can constrict their prey, which consists of mostly lizards and bats.

Sun Photosphere Fun


See our nearest star for details


The visible surface of the Sun, the photosphere, is the layer below which the Sun becomes opaque to visible light. Above the photosphere visible sunlight is free to propagate into space, and its energy escapes the Sun entirely.

Seen the image of Christ in any objects yet?

Pareidolia refers to the human habit of looking for the familiar in the unfamiliar.


Common examples are perceived images of animals, faces, or objects in cloud formations, the "man in the moon", the "moon rabbit", and hidden messages within recorded music played in reverse or at higher- or lower-than-normal speeds.

Pareidolia can cause people to interpret random images, or patterns of light and shadow, as faces. A 2009 magnetoencephalography study found that objects perceived as faces evoke an early (165?ms) activation of the fusiform face area at a time and location similar to that evoked by faces — whereas other common objects do not evoke such activation. 

This activation is similar to a slightly faster time (130?ms) that is seen for images of real faces. The authors suggest that face perception evoked by face-like objects is a relatively early process, and not a late cognitive reinterpretation phenomenon. An fMRI study in 2011 similarly showed that repeated presentation of novel visual shapes that were interpreted as meaningful led to decreased fMRI responses for real objects. These results indicate that the interpretation of ambiguous stimuli depends upon processes similar to those elicited by known objects.




These studies help to explain why people identify a few circles and a line as a "face" so quickly and without hesitation. Cognitive processes are activated by the "face-like" object, which alert the observer to both the emotional state and identity of the subject – even before the conscious mind begins to process – or even receive – the information. The "stick figure face", despite its simplicity, conveys mood information (in this case, disappointment or mild unhappiness). 

It would be just as simple to draw a stick figure face that would be perceived (by most people) as hostile and aggressive. This robust and subtle capability is hypothesized to be the result of eons of natural selection favoring people most able to quickly identify the mental state, for example, of threatening people, thus providing the individual an opportunity to flee or attack pre-emptively. In other words, processing this information subcortically (and therefore subconsciously) – before it is passed on to the rest of the brain for detailed processing – accelerates judgment and decision making when alacrity is paramount. This ability, though highly specialized for the processing and recognition of human emotions, also functions to determine the demeanor of wildlife.
