Two things

1. I love volleyball. It is probably my favorite sport, nope, it is. I am having trouble deciding it if I like it better than baseball back when I was in my prime. Maybe, just maybe. Especially beach volleyball, what's better than a day at the beach? I could go into details about all the specific things that I like about volleyball, but I don't think that is very important for you to know at the moment :P.

2. I just read an article that was trying to find the cellular processes that allow birds to flock together, fish to combine into schools and swim together, as well as other similar situations. Think about a giant school of fish swimming, they make turns, sometimes sharp turns, especially with a predator present - yet all the fish somehow stick right on each other, as if some choreographer was directing the swimming. How is this possible? Well the researchers were looking at what makes collective behavior. The study looked at Dictyostelium, which is a slime mold, they measured the chemical release of a certain part of it, finding that once this chemical amount reached a certain critical point, the cell started firing in a pulsating fashion sending more amounts of this chemical to the neighboring cells - prompting them to pulsate as well. Eventually, this lead to the cells growing in sync with each other and then the unified movement of the slime mode. How interesting is that? This research field also goes along with how humans have cells that turn into organs, how does that happen? We have clumps of cells that bind together and become our heart, our liver, our spleen. Have you ever stopped to think how these organs come into place? They definitely weren't in the sperm and the egg, somehow (probably in the way I just described) our cells come together to form them. So amazing. Biophysicists did this study, just chart that down as another field I want to tackle... gah!
