These drawings, which first appeared in the journal Advances in Protein Chemistry in 1981, became known as ribbon diagrams. Richardson’s drawing style was quickly adopted. Structural biologists ...

Inspired by professor of climate science Ed Hawkins' climate warming stripes, the air quality stripes depict particulate matter (PM) concentrations in 176 cities worldwide since 1850. These tiny ...

With research still ongoing, using stem cell hair transplants as a way to regenerate hair growth looks promising. The procedure, however, is not yet FDA approved. A stem cell hair transplant is ...

Female anatomy includes the internal and external structures, including those responsible for hormones, reproduction, and sexual activity. The female reproductive system is essential for hormone ...

Pluripotent stem cells are cells that have the capacity to self-renew by dividing and to develop into the three primary germ cell layers of the early embryo and therefore into all cells of the ...

Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated ...
