I love an area in biology called molecular and cellular biology.
Molecular biology is the biology of the molecules inside cells, things like proteins and DNA.
Cellular biology is the biology of how cells work, and this is things like signalling pathways which are the paths different molecules take to make the cell do something.
So if you combine molecular biology and cellular biology you can get a really nice explanation of what is going on inside cells and how that affects the cell overall.
I can’t stand molecular biology and genetics (sorry Matt) – it’s all too fiddly. I like system biology and looking at whole life forms right from bacteria to plants to humans! I got interested in human systems at uni – especially how humans sleep and think.
That’s how I got interested in learning and how best to teach people different things – like CPR!
At school I preferred physics and chemistry over biology but as someone that spends a lot of time outdoors ecology is really important, as is sustainability.
I really like something called EvoDevo (the shorter name for Evolutionary Developmental Biology) which is trying to understand how changes to the DNA of an animal can affect how it develops as an embryo, and how this process has led to the amazing diversity of life on the planet. As an example, trying to understand not only how a limb develops, but trying to find out the differences which can mean you either develop a hand, a wing or a flipper. I don’t work in this area so much anymore but I’ve always found it fascinating!
