Gene mutations can alter an individual’s hemoglobin in ways that curl their blood cells. This can cause painful sickle cell disease.
An army of cells — and their protein arsenal — work to keep us safe. Several squads of special forces possess unique superpowers to disable or kill intruders.
Cellulose is an abundant natural polymer found in plants and algae. It’s used to make everything from paper to clothing.
Life as we know it depends on the coordination of structures inside cells — whether a living thing has only a single cell or trillions of them.
The treatment helped frogs grow working limbs useful for swimming, standing and kicking. It’ll be a while before people can do that.
Eukaryotes are living things whose cells package their genetic material inside a pouch called a nucleus.
Scientists are teasing out the many ways the spiders’ vision, listening and taste senses differ from ours
A fat molecule's three long chains of carbon and hydrogen atoms repel water, stash energy and keep living things warm — even in the bitter cold.
Tardigrades often live in cool, damp moss. Their cushy life has somehow prepared them to survive the lethal radiation of outer space.
