Kinesin is a protein that moves things around the cell. That filament is a protein strand that gives the cell structure. That vesicle is a big blob full of cellular product that the cell wants to transport somewhere else. It is driven by ATP hydrolysis. (Source) (Video)

Hi there folks.Back with you once again here and I just want to just upload this drawing of a door knob.I know it’s crazy of me in posting this but I thought that I would just show off my skills on this blog and my Twitter account.It’s mostly a mechanical drawing I think but used mostly in architectural drawings but mainly it’s a mechanical drawing. 

//A-na5.tumblr #processing int N = 100; int r = 125; float thetastep = PI/34; float[][] dx = new float[N][N]; float[][] dy = new float[N][N]; float[][] dz = new float[N][N]; float d, x, y, z; float theta = 0; void gen(float t) { for (int i = 0; i < N; i++) { for (int j = 0; j < N; j++) { dx[i][j] = map(i, 0, N, -1, 1); dy[i][j] = map(j, 0, N, -1, 1); dz[i][j] = noise(sin(TAU/N*i+t)*sin(TAU/N*j+t)); } } } void setup() { size(500, 500); frameRate(17); colorMode(HSB, N); noStroke(); } void draw() { background(0); gen(theta); for (int i = 0; i < N; i++) { for (int j = 0; j < N; j++) { d = sqrt(pow(dx[i][j],2)+pow(dy[i][j],2)+pow(dz[i][j],2)); x = dx[i][j]/d*r; y = dy[i][j]/d*r; z = dz[i][j]/d; fill(z*N, 10, N); ellipse((x)+width/4, (y)+height/2, z*2, z*2); ellipse((dx[i][j]*r)+width/4*3, (dy[i][j]*r)+height/2, z*2, z*2); } } theta += thetastep; }

How the Geneva Drive (the mechanical step that makes the second hand on a clock work by turning constant rotation into intermittent motion) works.
