discere-et-docere:

A cell undergoing mitosis! 

Journey of Mitosis (Cell Reproduction): 

1. Interphase: Period of growth and replication of DNA. (90% of cell’s life). 

G1 Phase: Period of regular growth; mitochondria and chloroplasts multiply.  

Synthesis: DNA is replicated (semi-conservative replication).

G2 Phase: Another period of growth in preparation of dividing. 

2. Prophase: Nuclear membrane breaks down, DNA condenses, spindle fibers appear. 

3. Metaphase: Chromosomes align and attached to spindle fibers. 

4. Anaphase: Sister chromatids (DNA) are split apart to either pole of the cell by the pulling of spindle fibers. 

5. Telophase: Nuclear membrane forms around DNA, chromosomes decondense, spindle fibers break down. 

6. Cytokineses: Cytoplasm divides. 

And the new cells start the cell cycle once more!

Scientists break down the physics and neuroscience behind Bruce Lee’s legendary one-inch punch, the bodily application of his famous "be like water" philosophy.

Drawing upon both physical and neuro power, Lee’s devastating one-inch punch involved substantially more than arm strength. It was achieved through the fluid teamwork of every body part. It was his feet. It was hips and arms. It was even his brain. In several milliseconds, a spark of kinetic energy ignited in Lee’s feet and surged through his core to his limbs before its eventual release.

[…]

Every bodily jerk has an apex of force. To not only maximize on that force — but to augment it — Lee perfectly synchronizes his movements, one after the other, linking them like boxcars on a train. To be sure, countless muscle men have been stronger than Lee, but few, if any, could deliver more more power than Lee with just one inch.

What makes the difference? Lee’s brain.

Or, one might argue, Lee’s mind.

The full article is well worth the read.

“They wandered the borderland for weeks seeking some sign of the Apache. Deployed upon that plain they moved in a constant elision, ordained agents of the actual dividing out the world which they encountered and leaving what had been and what would never be alike extinguished on the ground behind them. Spectre horsemen, pale with dust, anonymous in the crenellated heat. Above all else they appeared wholly at venture, primal, provisional, devoid of order. Like being provoked out of the absolute rock and set nameless and at no remove from their own loomings to wander ravenous and doomed and mute as gorgons shambling the brutal wastes of Gondwanaland in a time before nomenclature was and each was all.”

- Cormac McCarthy, Blood Meridian (via robcam-wfu)

I consider myself a dedicated reader…or at least did until I saw this.

I’m glad I’m not the only person who used multiple colours of highlighter and pen in order to mean different things. I have different styles of post-it notes too.
