Catalyst Volume 21 Issue 2
This issue of Catalyst includes the following articles:
Looking at how the laying of telegraph cables across the ocean bed has led to the science of oceanography.
This careers article looks at working with laboratory animals and their ethical treatment.
Knowledge of the human genome has increased greatly during the last 10 years, and the genome sequencing technique has become much faster.
The investigation by geographers of two tectonic plates which are separating in northern Ethiopia and how eventually a new ocean will form as a result.
The organisms which live in soil, including worms and mycorrhizal fungi, are vital for keeping soil healthy and productive.
The analysis of tiny residues of fats found in ancient pots allows archaeologists to determine which animals were being raised in the Neolithic period.
Pterosaurs were flying reptiles which died out along with dinosaurs. Analysis of the fossil record has increased our knowledge of these creatures and how they lived.
This Catalyst article looks at how the laying of telegraph cables across the ocean bed led to the science of oceanography. Over two thirds of the Earth’s surface is covered in sea which can reach depths of 11 000 metres. The article looks at the challenge of laying cables in this environment and the history of the...
This Catalyst article describes what it is like to work with laboratory animals, ensuring that they are treated ethically. The article focuses on the career of an animal technician making the point that a degree is not essential to pursue a career in science. There are many positions available each year for lab...
This Catalyst article looks at how our knowledge of the human genome has increased greatly during the last 10 years, and genome sequencing techniques have become much faster. On 26th June 2000 it was announced that scientists had completed a first draft of the human genome, the DNA instructions for making a human...
This Catalyst article describes how, as two tectonic plates separate, wide fissures appear in the ground in northern Ethiopia. Eventually a new ocean will form in the area affected. The Earth’s surface is not stable or permanent. The tectonic plates that form our planet’s outer crust are constantly moving around,...
