Cellular Communications

When we talk about ‘cellular communcations’, we are not referring to use of a cell phone, because before mobiles or cell phones there was a time when this only meant cell to cell interaction within an organ or tissue.

Are Rewards the Right Approach? Written By You

14-year-old Gabriella told us that her school gives lots of rewards for doing well, or for good behaviour. It got her thinking about reward systems, and if they are a good idea.

I’ve only ever stolen something once. Twice then. OK! I’ve stolen eight times! Where else am I supposed to get money from (not including vulnerable children’s purses)? But, I’ve been thinking… Maybe, just maybe, it would be a slight possibility – just a slight one – that I could consider starting afresh. By ‘afresh’ I mean a new life in which I give up all my addictions, that are slowly rotting my bones, and make lasting friendships, that won’t break. Ever.
