Complicatedly Colourful: Vision Science

The picture I’ve put up is one of a mouse retina. The green dots are cells that have been stained with a fluorescent dye. I’m showing you this partly to show you how many cells there are in a retina (only some of the cells are stained, and humans have even more than mice). It’s also partly to (more…)

Life: DNA – Translating Life

This is probably all the basic understanding of DNA that you will ever need (especially if you are a non-scientist). If you are a molecular biologist, than this is just the beginning!

Turning DNA into proteins (and thus creating life) is split into two distinct steps:

  1. Transcribing. (Meaning to write out)
  2. Translating. (So translating the written out code into proteins)

Lets start.

Life: DNA – Breaking The Code

To start off on this massive topic I would like to note a couple of key concepts: (more…)

Life: “It’s all in the DNA'”

Before I get started I want to start with the reasons why DNA is so important.

Life: What We’re Made of Part 2 (The Molecules)

I could have gone on to bigger things after the cell, but I thought it would be worth covering this bit first. I mentioned that the cells control molecules which in turn control atoms. I want to quickly explain what those molecules are. (more…)

Life: What We’re Made of Part 1 (The Cell)

This bit has taken a lot of doing so I’ve decided to split it up over a few posts.

I’ve said so far that the world is made of atoms (and I expect to say at some point what atoms are made of) as are all things living. Yet this only explains so much. Atoms are nice as building blocks, but they don’t just randomly create life, they have to be expertly controlled. So to make life, atoms need to be controlled and this role is filled by much bigger molecules. (more…)

What is Life?

I’ve decided the best place to start this blog on explaining science, is to do a series of posts on something that’s a important to everyone, and is

probably¬†one of the most important aspects of science, I’m going to base the next few posts on Life.

The series will most likely include:

– Some stuff on cells and what we are all made of.

– DNA and the ‘code of life’ (or how we create life).

– This might be controversial to some people but I think it’s pretty important: evolution.

– Thoughts on consciousness and various theories on how we think and the existence of free will.

– As an afterthought I could do a small exploration into the universe and how it supports life, as well as whether there is life outside of this planet (or solar system).

If anyone at any point comes up with other suggestions feel free to comment on the blog and I’ll see if I can get to it!
