Think biology is all animals, plants and body parts? Find out how scientists are applying advances in technology, computing and engineering to develop better models of human health and disease and replace the use of animals.
How to build a brain
Selina Wray
(Professor of Molecular Neuroscience)
Learn more about how scientists study the ultimate biological computer – the human brain. Where once in vitro approaches were limited to looking at neurons in a dish, researchers can now create complex 3D brain organoids using a patient’s own cells, using them to replace animal models and accelerate the development of new treatments for neurological disease.

Microbiology meets microengineering
Victoria Chu
(PhD student)
Body-on-chip technologies harness advances in microfluidics and tissue engineering to create miniature models that can be more relevant to human biology than standard cell-based approaches or animal experiments. Hear about a new device linking three different organ models that allows scientists to study bacteria as they move through pelvic organs and test new treatments for urinary tract infections
