Cells, Microbes & Viruses / How do stem cells divide?

« on: 12/04/2008 11:03:21 »

Hi, I have just listened to the podcast on stem cells and I am wondering where this all fits in with normal cell division. Do differentiated cells divide when they get to a certain size or are they produced by stem cells dividing?

Physiology & Medicine / Have I "googled" my brain?

« on: 12/04/2008 10:46:18 »

Hi, I am slightly worried that constant use and easy access to Google is affecting my ability to recall information. Before the days of Google if I needed to remember some information I would think and think and eventually it would come to me. Nowadays as long as I have access to a computer I have instant access to the answer and my recall seems to have got a lot worse. Has a lack of use affected the physical structure of my brain or is this what getting older is like?
