Biology is the study of living things and how they grow, move, survive, evolve and reproduce. By studying humans, animals, plants and bacteria, biologists strive to improve our understanding of life itself. Biology has particularly close links and often overlaps with the fields of medicine and chemistry, and the research done by biologists saves and improves the lives of millions of people every day.

Biology is a very diverse discipline, with some biologists studying the smallest of organisms while others focus on entire ecosystems, and some even studying creatures from the past.

We've published 47 articles and 61 specialist blog posts about biology so far, featuring 632 unanswered biology questions! But we're not done yet as we still have another 230 biology research areas in our database to write about, so come back soon!

Twins
Scientists are very interested in twins because it helps us identify the differences between genetic and environmental factors that influence health and behaviour.

Unusual pregnancies
From two wombs to signs of pregnancy without an actual pregnancy, reproduction can be weird, wonderful, and sometimes scary. So what are some of the weirdest pregnancies out there?

Bovine TB
There’s still a whole herd of things we don’t know about bovine TB, its nature, spread and the effects of badger culling: could culling reduce it - or make it worse?

Toxoplasmosis
Can the toxoplasma gondii parasite change our personalities, behaviours and who we're attracted to?

Hormesis
At low concentrations toxins, drugs, radiation and other “stressors” may improve health rather than damage it. Scientists are looking into why.

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.
