incubator
A special warm box that helps babies, eggs, or cells grow.
An incubator is a special enclosed space that provides warmth, protection, and carefully controlled conditions to help something fragile grow and develop.
In hospitals, incubators are clear boxes that keep premature babies warm and safe. These tiny newborns aren't ready for the outside world yet: their bodies can't regulate temperature well, and they need extra protection from germs. The incubator does what the mother's womb would have done if the baby had stayed inside longer, giving the infant time to grow stronger.
Farmers use incubators to hatch chicken eggs. The machine keeps the eggs at exactly the right temperature and humidity, turning them regularly just like a hen would. After about three weeks, fluffy chicks begin pecking their way out.
In the business world, an incubator is an organization that helps new companies get started. A startup incubator might provide office space, mentorship, and connections to investors, supporting young businesses during their vulnerable early days.
Scientists also use incubators in laboratories to grow bacteria and cells at precise temperatures.
