Cells make up all life on Earth. Cells are the smallest unit of life. All cells have specific structures, called components. Models in science are used to help us understand complicated ideas in a ...

A researcher holding human embryonic stem cell cultures in 2004. In the new research, scientists use human stem cells to make models similar to human embryos. The models cannot develop into fetuses.

Scientists have created living entities that resemble very primitive human embryos, the most advanced example of these structures yet created in a lab. The researchers hope these creations, made from ...

Scientists are using human stem cells to create a structure that mimics a pre-embryo and can serve as a research alternative to a real one. They say these “blastoids” provide an efficient, ethical way ...

In a world first that challenges what we thought we knew about biology, scientists have successfully engineered animal cells that can photosynthesize. The breakthrough promises to revolutionize ...

Using mathematical analysis of patterns of human and animal cell behavior, scientists say they have developed a computer program that mimics the behavior of such cells in any part of the body. Led by ...

Our body's ability to detect disease, foreign material, and the location of food sources and toxins is all determined by a cocktail of chemicals that surround our cells, as well as our cells' ability ...

LONDON – Scientists have used human embryonic stem cells to create an embryo-like research model to help them study some of the earliest stages of human development. The model overcomes some of the ...

Researchers have achieved an astonishing feat: creating functional mouse stem cells capable of developing into a living mouse using genetic material from choanoflagellates, single-celled organisms ...

A colorful, intricate diagram circulating on social media is being presented as a groundbreaking picture of a human cell. "This photo is the most detailed model of a human cell to date, obtained using ...

Save guides, add subjects and pick up where you left off with your BBC account. Cells make up all life on Earth. Cells are the smallest unit of life. All cells have specific structures, called ...
