Frequently asked science questions answered
How does climate change actually work?+
Greenhouse gases like CO₂ trap heat in the atmosphere. Burning fossil fuels increases CO₂ concentrations, warming the planet and disrupting weather patterns, sea levels and ecosystems.
Ask a follow-up question →How do vaccines protect you against disease?+
Vaccines train your immune system using a harmless version of a pathogen. Your body learns to make antibodies without you getting sick, providing protection if you encounter the real disease later.
Ask a follow-up question →What is DNA and why does it matter?+
DNA is the genetic blueprint found in every cell of your body. It contains instructions for building all the proteins your body needs and determines your inherited traits.
Ask a follow-up question →How do black holes form?+
Black holes form when a very massive star collapses at the end of its life. Gravity becomes so strong that not even light can escape — hence the name "black hole".
Ask a follow-up question →Why do we age and can it be slowed down?+
Aging is caused by DNA damage, telomere shortening and cellular senescence. A healthy lifestyle — exercise, good sleep, stress management and diet — can slow the biological aging process.
