Bill Porter in Conversation with Howard Anderson
Some of the lessons Bill Porter picked up as a 13-year-old ranch hand in Colorado seem to have lasted a lifetime. When his boss told him to drive over a treacherous mountain pass into town for some chicken feed, Porter said he could not yet drive. He was told, “Just do it.” And when he faced taking a team of horses out to pas

Luminescent Solar Concentrators Explained
Researchers are well along in designing a highly efficient, inexpensive solar cell, but the big barrier to the dissemination of solar power in society remains the problem of installation, says Marc Baldo.

As an engineer, Baldo expresses confidence that “we’re going to mow down” the problem of producing a g

This Unit looks at how units if inheritance are transmitted from one generation to the next. First you will look at what happens to the chromosones of animals and plants during the process of sexual reproduciton. Then you will examine how genes are transmitted in particular patterns from generation to generation. These two approaches combine to illustrate how the patterns of inheritance can be explained by the behaviour of chromosomes during sexual reproduction.

Jupiter and its moons
Jupiter has long been an object of wonder, with its dramatic Great Red Spot, its numerous and varied satellites and the stunning collision of the comet Shoemaker Levy 9 with the Jovian atmosphere in 1994. This unit will introduce you to our solar system's largest planet and its major satellites and the history of their exploration. First publ

Fungal footbaths could save the honey bee
Globally, the honey bee population is in decline. This has serious implications for the cross pollination of commercial crops and wild plants. One of the major causes of this decline is the Varroa Destructor mite. However, researchers at Warwick University may have found a natural solution to this problem. Dr Dave Chandler from Warwick HRI explains how.

From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators. This is the fourth unit in the ‘Studying mammals’ series.

13.1 Introduction

I'll now introduce you to some different storage media and devices. As the uses for ICTs have expanded and developed, so has the need to store ever larger amounts of data. I've quoted some figures for storage capacity in this section but, given the rapid rate of development in ICT systems, some of these figures may be out of date when you read this unit.

1.3 Nucleic acids and the flow of genetic information
This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nu

Learning outcomes
Health, safety and risk assessment are of paramount importance both in the laboratory and the field. This unit will help make you more aware of the hazards and risks involved in laboratory and field-based research work, as well as giving you an overview of the legal requirements attached to this work. The unit discusses issues involved in the handling chemical and biological agents, basic safety procedures and common field-work hazards.

In the 18th and 19th century evolutionary biologists, including Darwin, emphasised the similarities between natural evolution and artificial ‘ improvement’ of livestock under domestication. They believed that studying domesticated animals and plants could illuminate the mechanisms of natural evolution.

5 Summary
The genetic manipulation of plants and animals and their use in agriculture is one of the most controversial scientific developments of recent times. This unt takes a look at the 'science behind the headlines' and the complex interactions between scientific and social factors. By the end of the unit it's hoped that you will have a clearer idea of both what is GM makes possible as well as what may be thought desirable.
