I want to make a partially working model of the digestive system that could digest complex carbohydrates. My ultimate goal is to be able to cut up some bread, put it into the model, operate it, and
The reason why I am wondering is because in biology normally nothing is ever just like that, there is always an exception. This would be the first biological rule without exception that I came acros
Can two plasmids with the same origin of replication (for example pBR322 ori) and thus from the same incompatibility group be successfully co-transformed in E. coli?
A few years ago, on my math's masters, I did a module in theoretical neuroscience. I was shown that the mathematical framework the course developed for neurons, with a small adjustment in the parame
Our Mouth are supposed to be the most contaminated regions on the human body so how come these mouth wounds heal in just about a week and don't get infected.

A friend of mine asked me this today, and I didn't know. I remember studying the menstrual cycle a few years ago, but I can't remember the details (other than it was very hormone-related), and so I
The human genome is about 770 MB, the C. elegans genome is about 100 MB, the yeast S. cerevisiae is about 12 MB. Different other genomes have been sequenced.
In mammals and birds the external reproductive organs and waste removal organs see to be the same.
Can sleep patterns be trained, or are they genetic? I read that a human needs to sleep at least 4 hours.

Has anyone optimized RT for long transcripts (9kb)? The downstream application will be PCR amplification and Illumina library prep. It will be trivial to make internal primers sets for the PCR that
Estrogen is a sturdy compound, very much like cholesterol. I was wondering if anyone had any idea how long it would survive in the environment, given that some people are concerned about it interrup
First, I think humans have been eating salt for a long time. This would mean that most likely, it is actually our 'instinct' to eat salt. Also, salt is eaten inevery culture today, which has the sam
