The world of science, from the perspective of a twenty-something bioinformatics student. I am a BSc Biology (Honours) graduate and am currently studying for an MSc in Bioinformatics and Theoretical Systems Biology.

Pain killers: worth the pain?

An article published in The Guardian highlights an on-going debate: are pain killers really worth the pain?

We are all aware that everything we consume has side-effects, though, this is dependent on the frequency and dose of consumption.

I am a strong believer in using diet and lifestyle to control one’s health. Perhaps if people stop eating McDonald’s every other day, they won’t get that random pain in their body and won’t need to take medicinal drugs.

Medicinal drugs should be a last resort, but, for most people, they are the first resort. This is where the problem lies.

The hidden reality of benzene poisoning

Follow this link and watch the video for an eye-opening and heart-breaking short documentary on the reality of benzene poisoning in China.

The chinese government and electronics industry turn a blind eye to save a few dollars. The only way to cause change is to spread the word and demand attention to the problem.

It is truly sickening to see how many peoples lives are ruined by this. Something needs to be done.

What is Bioinformatics/Computational Biology?

The combined use of mathematics, statistics and computation in biological research.

Applications include the following, which can loosely be listed in order:

- Processing, analysis and organisation of large amounts of experimental or raw (for example, DNA sequences) data.

- Predictions based on these data.

- Ab initio research using simulation by sophisticated software based on these data to produce novel ideas which then need to be experimentally verified.

- Systems and Network Biology: The organisation of these data and predictions to form networks perhaps leading to discovery of potential relationships between entities that may have otherwise been unknown.
