Extraterrestrial life
The search for alien life catches many people's imagination and has always been a very public branch of science. So with all this investigation, why has our search revealed nothing? Are we truly alone in the Universe?

Learning
From the moment we are born, we begin to learn about the world around us, and this continues for the rest of our lives. But exactly how does this happen in the brain?

Vision
Vision is arguably a human's primary sense- we use it to spot danger and navigate our environment. Despite this, there is still plenty we don't know about how this sense works.

Senses
Our senses allow us to explore and interact with the world around us. Even the simplest living organisms have some way to sense their environment - and some animals can sense in ways we can't even imagine!

TWDK magnifying glassBiochemistry is a broad area of chemistry covering the chemical processes involved in life itself.

TWDK magnifying glassBiomechanics applies the principles of physics and engineering to understanding biological systems.

TWDK magnifying glassBiomedicine looks at the underlying mechanisms of disease.

TWDK magnifying glassBiophysics uses the principles of physics to study life at every level, from atoms and molecules, to cells, organisms and environments.

TWDK magnifying glassCytology also known as cell biology, cytology is the study of cells - the building blocks of life.

TWDK magnifying glassDevelopmental Biology is the study of how organisms grow and develop, from how genes influence cells, to how organisms change throughout their lives.

TWDK magnifying glassEcology is the study of how organisms affect, and are affected by, their environment.

TWDK magnifying glassEvolutionary Biology looks at how plants and animals are affected by the process of evolution by natural selection.

TWDK magnifying glassGenetics is the study of genes - the stretches of DNA found in almost every creature which acts as the blueprint for their bodies.

TWDK magnifying glassMicrobiology is the study of the smallest, usually single-celled, organisms such as bacteria and viruses.

TWDK magnifying glassMolecular Biology looks at the structure of cells, and the systems within them at the molecular level, to understand how they work and interact.

TWDK magnifying glassNeuroscience is the study of the central nervous system, including the brain.

TWDK magnifying glassPalaeontology is the study of life which existed prior to the current "Holocene" geological epoch.

TWDK magnifying glassPhotobiology is the study of how cells and organisms change physically and chemically in response to non-ionising radiation.

TWDK magnifying glassPhysiology focuses on organisms at the system level. It aims to explain how these systems, which can range from a single cell to a whole organism, carry out their functions.

TWDK magnifying glassRadiobiology studies the effects of ionising radiation on living organisms.

TWDK magnifying glassZoology or animal biology, is the study of biology relating to the animal kingdom.
