Cells can spontaneously change shape even without external signals, but the underlying mechanisms behind this form of ...
Every time a white blood cell engulfs a bacterium, a neuron extends a projection to connect with a neighboring cell, or when a cancer cell forcefully squeezes through tissue to spread, the cell must ...
How large, fully folded proteins can pass through cell membranes without destroying them has long been one of the open questions in cell biology. Using cryo-electron microscopy (cryo-EM), Leonid ...
Stretching protein samples in all directions pulls molecules farther apart, allowing them to be visualized using only light ...
Each year, doctors treat more than 6 million bone fractures in the United States. And while it takes only a few seconds for a ...
Biomedical engineers at Duke University have developed a technique to noninvasively visualize the brain's waste-removal system in unprecedented detail. This new imaging approach allows researchers to ...
A century after one of developmental biology’s most influential experiments, researchers have revisited the concept of the embryonic “organizer” in one of the oldest animal lineages alive today.
