Figure 1: Expected dynamics of attaining homoplasmy by somatic mtDNA mutations in a continuous cell lineage. To test this prediction, we analyzed the noncoding regions of 24 buccal epithelial cells ...

Negative-stiffness mechanical isolators can be used for achieving high-performance vibration isolation in a small microscope platform. It can be challenging to use microscopy for imaging materials, ...

Electrical engineering students rarely leave college with knowledge depth in both digital electronics and RF/microwave theory. The new engineer with digital design skills likely chose that path from a ...

In the late 1800s a German physicist named Heinrich Hertz created radio waves in the laboratory. A century later, we are still expanding upon Hertz’s discovery. Radio waves make possible all wireless ...
