In recent years scientists have made synthetic versions of key parts of the cell, such as chromosomes and ribosomes. Now researchers have developed the first working artificial prototype of an “organ” of a human cell—the Golgi apparatus.
Made up of a network of sacs piled together like a stac... Read More
Microscopes have been around for some 400 years, and today they are even accessible via customized cell phones.
