To demonstrate the method, the team printed a range of tiny shapes, including a 10-micrometer elephant, laboratory logos, ...

Deep within the nucleus of every cell lies a structure smaller than a pinpoint that may hold the secret to aging. Scientists at Weill Cornell Medicine have discovered that the nucleolus, long known ...

Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play ...

Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers.

The beta cells of the pancreas are responsible for releasing the hormone insulin, which is vital for the absorption of glucose from the bloodstream. Various factors can impair the ability of these ...

With the long-term goal of creating living cells from non-living components, scientists in the field of synthetic biology work with RNA origami. This tool uses the multifunctionality of the natural ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

Researchers have developed a way to 3D print custom micrometer-sized structures directly into the interior of living cells.

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

How the Cell's Internal Framework Shapes Brain Development Actin plays a central role in the cytoskeleton, the internal framework that gives cells structure and helps move materials inside them. In ...
