Discovering Science: Global Challenges
This course is part of the Discovering Science program, which will enable you to learn about the extraordinary world of everyday chemistry, and earn 10 academic credits from the University of Leeds.

Find out how the Penicillin class of antibiotics has been a major breakthrough in the treatment of patients. However, with bacteria developing efficient ways of resisting antibiotic treatment, discover how scientists are treating patients with infections resulting from resistant bacteria.

The world’s population is approaching eight billion people, putting increasing strain on our ability to feed everybody. Explore the strategies currently being developed, and the role that chemistry plays in finding solutions to food security.

Skip to 0 minutes and 10 seconds Examine today’s global challenges with leading academics, and explore possible solutions to some of the greatest threats we face today. In week one, Professor Colin Fishwick introduces the rise of the superbugs and the challenge of bacterial resistance to antibiotics. Understand how bacteria have developed a resistance, which scientists fear could lead to a return to a pre-antibiotic era. Find out how advances in research are helping to overcome this resistance. In week two, Professor Steve Marsden highlights some of the challenges of feeding a growing population, presenting two alternative methods of agriculture. He explores the use of GMOs and organic farming and discusses the effects of changing diets on food production.

Syllabus

  • Week 1

    The fight against bacteria

    • Welcome

      Welcome to Discovering Science: Global Challenges. This course explores two topics related to global challenges: the fight against bacteria, and feeding a growing global population.

    • Historical perspectives

      In this activity, you are introduced to the history of penicillin and the research behind antibiotic development.

    • Science in action

      In this activity, you hear from a consultant in infection and travel medicine regarding her clinical research, and hear reflections on the case study.

    • Future perspectives

      In this activity, through the use of scenarios, you consider the ethical issues associated with powerful medicines, and reflect on the appropriate uses of them.

    • Revision

      This revision activity provides further opportunity to explore the topics covered this week. It is recommended that you join this activity if you have signed up for the program and are working towards academic credit.

    • Summary

      To close this week of the course you have the opportunity to reflect on the week and explore the glossary.

  • Week 2

    Feeding a growing global population

    • About Week 2

      This week you will find out about the challenges of feeding a growing population, and some of the strategies and interventions that are necessary. You’ll look at the discovery of fungicides from a naturally occurring molecule.

    • Historical perspectives

      In this activity, you hear from Professor Steve Marsden about the use of chemistry in addressing the challenges of feeding a growing population.

    • Science in action

      In this activity, you hear from a synthetic chemist about the natural origins of a fungicidal agent. Dr John Clough looks at how it was developed to become the world’s most widely used product of its type.

    • Future perspectives

      In this activity, you’ll explore alternative methods of agriculture including genetically modified organisms and organic farming. You will also compare uses of natural crops and their genetically modified alternatives.

    • Revision

      This revision activity provides further opportunity to explore the topics covered this week. It is recommended that you join this activity if you have signed up for the program and are working towards academic credit.

    • Summary

      Paul reflects on the week through a summary of discussions, questions and comments. There is also an opportunity for you to test your understanding and find out more about the other courses in the program.
