RuBisCO. The most abundant enzyme on earth. This enzyme catalyzes the fixation of CO2 to the 5- Carbon RuBP molecule setting of the Calvin Cycle in the Stoma of Cholorplasts. Even though It has 8 active sites, it is a slow enzyme only catalyzing around 3-10 CO2 molecules per second. This is partially due to atmospheric oxygen acting as a competitive inhibitor to CO2.
“We can look at neurons as individuals, but that doesn’t reveal a lot,” Zeringue said. “Neurons are more connected and interdependent than any other cell in the body. Just because we know how one neuron reacts to something, a whole network can react not only differently, but sometimes in the complete opposite manner predicted.” Zeringue will next work to understand the underlying factors that govern network communication and stimulation, such as the various electrical pathways between cells and the genetic makeup of individual cells. (via Scientists recreate brain cell networks providing view of activity behind memory formation) this means that the main emphasis in neurological studies of neurons do not lie in individual neurons, but in their relationships with other cells in the body.
Rat cortical neurons and glia in mixed tissue culture stained with Chicken antibody to MAP2 (green), mouse monoclonal antibody to GFAP (red) and nuclei of all cells stained with Hoechst dye (blue).
The MAP2 antibody was used at a dilution of 1:30,000 and the GFAP at a dilution of 1:100 using our standard fixation and staining procedure (described here). To order these antibodies go to our order form (here). Picture taken with a Zeiss 20X objective and documented with a Digital SPOT camera
Neuroplasticity is like how bones work. As you use a bone there are organisms inside the bone (marrow) and they are constantly weakening and strengthening the bones in the places needed. For a runner it could be in the outside of the left femur, while the right femur may become weaker, sincer the runner is running around an oval track in a reverse-clockwork motion. This example is not scientifically ccurate but i hope it helps to serve to show you how bones work. The neurons and glial cells in the brain are similiar. When a cortical pathway is activated to do some sort of action, such as dribbling a basket ball, certain neurons in the brain are activated and they are shown through a cortical map. Therefore, synapses are clipped and grown in response to the amount of “traffic” done on certain cortical pathways. (I have no idea if this theory has any value at all) http://en.wikipedia.org/wiki/Neuroplasticity
In reproduction you have pheromones which give off scents that are used to attract mates. However, scientists are still a little blurry on the pheromones that humans give, many believe, that humans no longer give off pheromones. I believe that pheromones given off by humans are in fact body odors and have been artificially created in the form of deoderant, body spray, cologne, and any other scented substance applied to the body. Pheromones however, are have evolved out of the reproductive importance in humans and been replaced by the visual and psychological aspect of reproduction.
The Humans have evolved other ways of communicating with mates, such as sight and especially the psychological avenues. Pheromones are a primitive way of attracting mates and has since been replaced by visual attraction technipues and psychological attraction. With the improvement of the eye and the growing of the brain over millions of years by evolution, attraction began to become more and more complex. For example, a peacock uses feathers to attract his mate rather than pheromones. this demonstrates how an organism uses the visual aspect of attraction rather than the pheromone one. Many marsupials do not use pheromones either. The psychological portion of attraction is reserved for those with a very evolved brain, i.e. Humans and other mammals. Since Humans have the highest level of brain formation, the psychological aspect of attraction is what is the most key in choosing a mate. For humans the visual attraction is very important, but the psychological one is the most important.
Due to this, we can deduce that pheromones have been, through natural selection, less and less important for Human attraction. 
I have known about “memes” for about 4 years. The first time I saw a meme was on the internet website 4chan. They were funny at first but then they got out of hand. Kids all over the place were putting up generic memes about how this makes me a bachelor or how you are not tech savy. So ridiculous. then you have a bunch of faggot posers going onto 4chan and flooding threads will gay meme permutations made from big websites like “memegenerator”. The meme died when people began making them out of photoshop and on web based programs.
I refuse to make memes because they degrade my dignity. I feel that if I were to make them I would be feeding into the newfag culture that has come to dominate 4chan’s now-dead body. I cannot handle buying into a sub culture that has killed something so beautiful.
