GTAC Scientific Animators have created a number of animations to illustrate biological processes and educate viewers. These animations feature in GTAC programs, online courses and other resources.
This animation describes the process of infection with Clostridium tetani and how the toxin it releases interrupts nervous control of our muscles, leading to tetanus. This loss of muscle control causes the convulsive muscle spasms typical of tetanus, which are so severe they can cause bone fractures and dislocations. Death often occurs due to respiratory failure or cardiac arrest. With adequate immunisation, tetanus is a completely preventable disease. However in developing nations, without comprehensive vaccination programmes, tetanus remains one of the top ten causes of death. Universal vaccination, including pregnant women, is vital to preventing this terrible affliction.
This animation describes the process of infection of the airways by Bordetella Pertussis, a bacterium which causes whooping cough. It specifically details how the bacterium damages ciliated airway cells, impairing normal respiratory function, leading to the severe coughing fits characteristic of whooping cough. Vaccination is vital to protect against this highly contagious disease, not only for ourselves, but also to protect those who cannot tolerate vaccination. This animation has been officially selected for the Raw Science Film Festival 2016 and the Doctors Without Borders Film Festival 2017.
A cell is an amazing, complex hub of activity. They are the site of many processes and reactions that are required for life. This animation features biological processes such as chemical signalling, transcription, translation, the protein secretory pathway, endocytosis and exocytosis in a macrophage.
Water is essential for our survival but we are constantly loosing it through urination, sweat and other means. This animation illustrates how dehydration stimulates the release of antidiuretic hormone (ADH) by cells in our brain. This results in increased water reabsorption in the kidneys and greater water retention in our bodies.
