Our Battle Against Bacteria

Posted on Leave a commentPosted in Biology, Health, Science News

For ages now we’ve been battling an increasing problem – all caused by antibiotics. Antibiotics have dated all the way back to 1928 after Alexander Fleming; a bacteriologist discovered penicillin at London’s St Mary’s Hospital. Since then, such a small idea has grown and blossomed into the antibiotics we know today and has saved over […]

The Risks and Benefits of Sunlight

Posted on Leave a commentPosted in Other

 Sunlight, composed of radiation in the form of electromagnetic energy at mixed wavelength is essential to the continued survival of living creatures on Earth, whether it be autotrophs using energy from sunlight to synthesize food via photosynthesis or heterotrophs using light to obtain food indirectly. The main source of Vitamin D that is so beneficial for humans is through sunlight and it helps keep the body especially the bone and neurological functions in good condition. While there are widely accepted benefits, it is equally imperative to be wary of the risk that comes with persistent sun exposure. Carcinomas of the skin contribute to 1.6% of all world-wide cancers and ultraviolet light that forms part of the spectrum of sunlight has been implicated as a carcinogen.

How Can the Problem of Rising Carbon Dioxide Levels Be Resolved?

Posted on 15 CommentsPosted in Other

It is widely accepted that carbon dioxide levels are rising. Past this point, there remains a series of heated arguments as to the effects of the rise and what steps we can, and should, be taking. In addressing these questions, it is necessary to consider both sides of the climate change debate, particularly the extent of our influence and the possible effects for us. The debate is often influenced by political, economic and even emotive factors, sometimes to the detriment of rationality. Firstly, this essay will argue that this problem is of such significance that it is essential to focus on the numbers, scientific evidence and data, not politics or emotion. The topic is broad, so the following analysis will focus primarily on the carbon neutral energy that must be the foundation of any possible future solutions in the UK.

Is Nuclear Fusion a Viable Source of Energy for the Future?

Posted on Leave a commentPosted in Other

In this article, I have discussed the merits and the problems of nuclear fusion. I have tried to answer my question of viability by discussing whether or not fusion is possible, and if it will ever be economically viable to do so. To do this, I have explored the current level of the science behind fusion, and where it could be progressing over the next fifty years or so. I also compared fusion to other sources of fuel, to see if it was the best option and so go into depth about the pros and cons of the different fuel sources. I concluded that fusion was needed as a replacement for fossil fuels, and that it would be the preferred method due to its safety, minimal damage to the environment, its longevity of resources, and its ability to create copious amounts of energy. I decided that fusion, whilst not at the moment, would become economically viable within the next forty to fifty years, and so answered my question, as I concluded that fusion is a viable source of energy for the future.
