Human cells are extremely small and tightly packed – at about 20 micrometers across, roughly one-fifth the width of a human hair, each cell contains a dense mix of proteins, organelles, and molecular ...

Cells aren’t as passive as scientists once thought—they actively create internal currents to move proteins quickly and ...

In a quiet lab at Utrecht University, researchers have built a tool that lets you watch one of life’s most serious crises unfold in real time. Inside every cell, DNA breaks, repairs, and sometimes ...

A new imaging approach is shedding light on one of cell biology’s most elusive questions: how lipids are organized and sorted within membranes.

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. (Nanowerk ...

Crystalline polymers assembled inside tumor cell lysosomes rupture membranes, release iron, and trigger immune-activating ferroptosis that shrinks tumors in mice. (Nanowerk Spotlight) Cells produce ...

A novel method has enabled scientists to 3D-print structures into live cells, paving the way for a new class of intracellular bioengineering tools and applications. In a first, scientists from the ...

Within tumors in the human body, there are immune cells (macrophages) capable of fighting cancer, but they have been unable to perform their roles properly due to suppression by the tumor. KAIST ...
