We've all struggled trying to shove magnanimous amounts of information for exams, be it vocabulary, geometry theorems, biology notes, chemistry reactions, physics equations or even just names of acquaintances we meet at weddings or the likes.  You might question whether after many years of non-stop learning, be it in a classroom setting, or just basic interactions and do's and don'ts, may we run out of space to absorb all the memories, events and information we encounter.

Our brain, unlike the brains of animals and lower ancestors, is not hardwired by instincts. In fact, we have very little in the field of instincts by comparison. Our brain is a learning brain. It is designed to absorb and interconnect information. Now, which of this inform ...

The importance of adequate, non-distracted, deep sleep could not be emphasized enough. Recent research has put the brain yet again under the spotlight, this time only to shed some light on one more reason we should be getting our sleep and why. Make sure to watch the video above. It is hands down, one of the best TED talks I have listened to. As for now, I'mma go make my CSF flush my amyloid betas Nighty, night!

Despite slang terms that imply otherwise, the human penis contains no bones. The same cannot be said for many of our closest evolutionary relatives: Chimpanzees and bonobos both have penis bones (a macaque one is pictured, left), also known as bacula.

To find out why some primates have the feature whereas others don’t, researchers traced the bone’s evolutionary history through time. The baculum first evolved between 145 million and 95 million years ago, as reported in the Proceedings of the Royal Society B. That means it was present in the most recent common ancestor of all primates and carnivores. Why some descendants, like humans, lost their bacula appears to be due to differences in mating practices: In primates, the presence of a penis ...

This is what all the white matter in your brain looks like. This complex 3D-printed model accurately reflects the 2,000 strands of nerve cells that branch through every human being's brain.
