Scientists have long known that cellular membranes vary in thickness, but measuring those differences inside actual cells has ...

Scientists have crossed a startling new frontier in bioengineering: they can now fabricate intricate three-dimensional ...

A new twist on two-photon polymerization has been used to deliver objects, including lasers and an elephant, directly into ...

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.

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair.

When a T cell encounters a cell carrying pieces of a virus or bacteria, the two form a tight contact point known as an immune ...

In a recently published study, researchers at Fox Chase Cancer Center revealed for the first time that cancer cells can evade anti-cancer drugs by entering and surviving within bone marrow fibroblasts ...

The constant, energy-driven motion inside living cells may generate electricity in a way no one fully recognized before.

RNA is usually portrayed as a molecule that works deep inside the cell, helping to turn genetic information into proteins. But new research led by Utrecht University scientist Jack Li shows that RNA ...

A cell nucleus reconstituted in vitro in Xenopus laevis (African clawed frog) egg extract. Left image shows a fluorescence image where DNA has been stained and right image shows a density map of the ...
