Researchers are working on the first-ever comprehensive map of all of the 37.2 trillion cells that make up the human body.

A large team of scientists—including 130 software engineers, mathematicians, computational scientists, biologists, clinicians, and physicists—hailing from Israel, the Netherlands, Japan, the UK, the U.S., and Sweden are hard at work mapping the human body on a cellular level.

Although a cell atlas has long been theorized, new biological tools and more powerful computers have turned this one-time vision into a reality. The team working on the atlas believes that they can draw comprehensive reference maps for all human cells in the body.

A human cell atlas would give the medical community a new way of understanding how our bodies work and how to diagnose, monitor, and treat disease.
