Mitosis: The Natural Cloning Process

All living organisms grow and reproduce. Eukaryotic organisms, which include you and I, accomplish this through a process called mitosis. During mitosis, a cell clones itself allowing its DNA to be replicated and distributed equally among two cells.

What is Meiosis?

Meiosis is a two-part cell division process in organisms that sexually reproduce.

Meiosis produces gametes with one half the number of chromosomes as the parent cell.

There are two stages of meiosis: meiosis I and meiosis II. At the end of the meiotic process, four daughter cells are produced.

Each of the resulting daughter cells has one half of the number of chromosomes as the parent cell.

Vision Screening Device Detects Diabetes

Friday July 18, 2008
Isn't it nice to be able to accomplish multiple things at once.

Just imagine going to the eye doctor for a vision screening and while you are there, you can find out if you are at risk for diabetes.

Yes, that's right, scientists have designed a vision screening instrument that can detect eye damage that is associated with diabetes.

In fact, this device detects a particular type of tissue damage that occurs even before the initial symptoms of diabetes.

The screening is non-invasive and involves taking a photograph of the eyes.
