Fire ecology free course icon Level

Science, Maths & Technology 

Fire ecology

This course explores the role of fire as a natural disturbance in ecosystems. It introduces the concept of a fire regime and its influence on the type and distribution of organisms that occur in fire prone ecosystems. It also looks at some of the adaptations of plants that have evolved in these ecosystems and how animals either avoid or exploit the consequences of fire as a natural disturbance. Finally it examines how fire can increase biodiversity by generating a mosaic of habitats within an ecosystem and briefly addresses some of the consequences of climate change and global warming on the intensity and frequency of fires.

Blood and the respiratory system

‘Don’t hold your breath’ is an expression you’ve probably heard many times, but may not have thought too much about. In this free course, Blood and the respiratory system, you’ll study why respiration is so important for life, including how air enters and leaves the lungs, how oxygen is transported in the blood, the many dynamic factors that control breathing, and some diseases that affect respiration.

Learning from major cyber security incidents

  As a society, we are now almost always connected to the internet and rely on it for many different day-to-day activities. However, this dependency on the internet can make us vulnerable to attacks.  Once a connected device is compromised, it is not only that particular device that is affected – it can also be used as a springboard to attack other devices in the same network and in others.  In this connected world, it is also inevitable that personal information is stored in large-scale government and commercial databases. Unfortunately, breaches of these large-scale databases happen fairly frequently and, when they do, personal information can be leaked which will make you, and millions of others affected, vulnerable to scams and other identity crimes.  This course analyses several cyber security incidents and looks at what lessons can be learned.

Metals in medicine free course icon Level

Science, Maths & Technology 

Metals in medicine

This free course, Metals in medicine, focuses on the use of metals and their compounds in the production of images of internal structures in our bodies and on the role of metal-containing compounds as drugs in the treatment of disease. In terms of medical imaging, the high atomic numbers of many metals, their magnetism and radioactivity have all been harnessed in a range of techniques to provide contrast between tissues and to highlight diseased or otherwise changed tissues. These techniques have become some of the most important weapons in our fight against disease. When considering drugs used for the treatment of disease, your first thoughts might lean towards treatments involving organic compounds. But metals and their compounds have been used for medical applications since ancient times. The use of metal-containing drugs is a wide-ranging, exciting and ever-expanding research area. In this course you will learn the underlying chemistry behind both uses of metal-containing compounds and see their major impact on human health.

What chemical compounds might be present in drinking water?

Do you want to know what’s in the water that you drink? This free course, What chemical compounds might be present in drinking water?, examines the chemical compounds that occur in drinking water. A high level of certain anions in water can cause environmental pollution and health problems. Cations are also important. For example, calcium salts contribute to the hardness of water and water treatment uses aluminium compounds. Additionally oxidising agents, such as ozone or chlorine, are vital in the disinfection of water. This OpenLearn course focuses on the chemistry of the p-block elements in Groups 13 to 18 of the Periodic Table.
