formerly a microbiology blog, this will now be a science blog, in which I post science only material. enjoy! p.s. I no longer teach microbiology, so I'm all out of original content, but reblogs will be plenty!

THIS WEEK’S QUESTION!
Every Sunday, a question will be asked about one of the images from the past week. Be the first to answer correctly, and your blog will be promoted on Monday’s image post and Biocanvas’s main site!
Due to their rapid rate of cell division, cancerous tumors require vast amounts of oxygen and nutrients in order to grow. To facilitate this need, tumors release factors that encourage the growth of new blood vessels in a process known as angiogenesis. Recently, the first anti-angiogenic drug, Avastin, was approved by the U.S. Food and Drug Administration as a treatment for cancer.
What is Avastin and how does it specifically work to prevent angiogenesis?
