Beautiful: Scientists create tiny beating heart cells

The human heart is a complex organ that is quite challenging to study in the lab in real-time. So, you can see why researchers at UCSF and UC Berkeley are  excited by the creation of tiny, 3D heart chambers with the ability to  exist and even beat in a lab dish.

The resulting heart chambers may be miniscule—measuring no  more than a couple of hair-widths across—but they hold huge potential  for everything from improving our understanding of cardiac development to  speeding up drug toxicity screening.
