1) The endless beauty of the mountains: Canadian Rockies
Ι feel so thrilled every time I see this icy wilderness.
2) Also, when a fish is thinking
...its brain is like this. This is the first time that the fishes' thinking process was videotaped. If you feel ready to take a deep in learning something more about neurons, take a look at this too.
3) What a squid does while listening to Cypress Hill.
This video below from the team over at Backyard Brains exists in the case that the previous video didn't blow your mind. First a minor detail: squids do not possess ears. However, the same impulses created when audio is converted to an electrical signal, like what happens inside a microphone, can actually be gently applied to tissue, in this case the dorsal side of a squid fin.
The video is a view through an 8x microscope zoomed in on the dorsal side of the caudal fin of the squid. We used a suction electrode to stimulate the fin nerve. Chromatophores are pigmeted cells that come in 3 colors: Brown, Red, and Yellow. Each chromatophore is lined with up to 16 muscles that contract to reveal their color.
A number of incredibly smart people even wrote a scholarly paper on the phenomenon aptly, find it here.
4) Leave the squids, we are going to Mpalos, Crete.
Some of you wondered if this paradise really exists. That video below is the vivid proof of its existence.
5) And for the end, some rest for your eyes.
I am sure that you need some.
