The Big Bang Of Bitcoin

2018-09-11T08:11:00+00:00

The Big Bang Of Bitcoin Bitcoin, defined as the ‘internet of money’ is a cryptocurrency and worldwide payment system created by Satoshi Nakamoto. Unlike other established institutionalised currencies, Bitcoin is the first of its kind as a decentralised digital currency. It is a decentralised currency in that the Bitcoin system functions without a single administrator or a central bank. The appeal of a cryptocurrency such as Bitcoin is that it isn’t physically owned by anyone, which means that it’s accessible to anyone. Bitcoin allows for ‘peer-to-peer’ transactions to take place through the use of cryptography. Cryptography refers to a means [...]

A Shot In The Shark

2018-09-10T15:52:44+00:00

A Shot In The Shark Shark attacks and the publicised subsequent statistics are often sensationalised by the media thanks to the likes of cinematographic and literary productions such as Jaws, Deep Blue Sea and Into the Blue. However, in reality, shark attacks occur relatively infrequently considering the human populations’ inadvertent everyday proximity to sharks. As the development and popularity of drone photography have shown, humans come into contact with sharks more often than they know, and often without any consequences or risk of attack. It is a well-known and acknowledged fact that your chances of being killed by a shark [...]

‘Globesity’ – A Big Global Epidemic

2018-09-10T15:46:15+00:00

‘Globesity’ – A Big Global Epidemic Globesity, a term coined by the World Health Organisation (WHO), refers to the escalating worldwide obesity epidemic. The classifications of being overweight or obese can be defined as “abnormal or excessive fat accumulation that may impair health” (WHO 2017).  Being overweight versus being obese is largely determined by a person’s Body Mass Index (BMI) which is a simple index of weight-for-height. In order to calculate a person’s BMI, weight (in kilograms) is divided by the square of the person’s height in metres: (kg/m2). An overweight adult is one that has a BMI greater than, [...]

The Real Scoop On Poop

2018-09-10T15:34:08+00:00

The Real Scoop On Poop The first thought when recycling comes to mind generally involves the re-appropriation and reuse of conventional materials such as plastic and paper-based products. The necessity and desire to recycle these materials is founded on the excessive general daily demand, consumption and production of all these products. However, the city of Durban, South Africa, is embarking on an even more ambitious recycling endeavour by utilising urine as a form of fertilizer and turning faecal matter into fly larvae feed which will, in turn, be utilised as feed for poultry and fish farms. A lack of access [...]

Vaping: all hot air, or a cause for concern?

2018-09-10T15:27:50+00:00

Vaping: all hot air, or a cause for concern? Vaping by now is not a new trend but has become increasingly popular over the past few years as a cigarette alternative, as well as a social smoking movement in its own right. Vaping, in essence, is the act of inhaling the vapour produced by a device such as an e-cigarette or vapouriser. The vapour that is inhaled originates from a specially formulated e-liquid or concentrate that mostly contains nicotine as well as a flavouring component. The vast appeal of vaping is associated with the fact that it is seen as [...]

Disposable plastics; is this the last straw?

2018-09-10T15:15:09+00:00

Disposable plastics; is this the last straw? Consider this; it takes 200 years for a plastic straw to break down completely. This means that every time we purchase and consume a beverage (most of which don’t actually require a straw), we are inadvertently creating a demand for a plastic product that will most likely only be used once, for a very short amount of time – but yet will remain a part of this planet long after we are gone. According to National Geographic magazine, Americans use a projected 500 million straws daily, each one with a lifespan of almost [...]

Hartebeespoort Hyacinth Crisis Continues

2018-09-10T15:03:54+00:00

Hartebeespoort Hyacinth Crisis Continues Eichhornia crassipes (E. crassipes), more commonly known as water hyacinth, is often considered to be the world’s worst aquatic weed. According to the Agricultural Research Council (ARC): it has gained its reputation as such due to its “invasive potential, negative impact on aquatic ecosystems, and the cost it necessitates to control it.” The water hyacinth can be classified as a herbaceous, free-floating aquatic plant that produces attractive lilac flowers and has submerged roots and doubles every 11 to 18 days. Once the water hyacinth has grown sufficiently, it is able to entangle its petioles (the spongy, [...]

In the Fabric of Time and Space.

2018-09-10T14:46:49+00:00

In the Fabric of Time and Space. On the 3rd of October, the Royal Swedish Academy of Sciences announced the recipients of the Nobel Prize for physics. The Nobel Prize in Physics for 2017 was divided among three recipients: one half was awarded to Rainer Weiss, and the other half was split between Barry C. Barish and Kip S. Thorne for "for decisive contributions to the LIGO detector and the observation of gravitational waves.”  All three scientists contributed key findings that led to the detection of gravitational waves within the fabric of time and space. The discoveries were made by [...]

World Car-Free Day 2017: Taking Back The Streets

2018-09-10T14:25:14+00:00

World Car-Free Day 2017: Taking Back The Streets The 22nd of September has become a day largely internationally recognised as World Car-Free Day. The first ‘car-free-days’ were held in Reykjavik, in Iceland, Bath in the United Kingdom and La Rochelle in France. However, the first national car-free campaign was initiated and inaugurated by Britain in 1997, followed by France in 1998. It became a European-wide initiative by the European Commission in 2000. It has subsequently spread to 1500 cities in 40 countries. The aim of the day, according to the Washington Post, is to “promote [the] improvement of mass transit, [...]
