Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Conceptual illustration of the bidirectional quantitative scattering microscope, which detects both forward and backward scattered ...

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 ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

What we breathe out becomes fuel for forests. But inside our own bodies, CO₂ has a secret life. It sparks chemical reactions, shapes metabolism, and may even act as a signaling molecule—and a new tool ...

Gram-stained section of a macrophage with ingested S epidermidis bacteria, seen as purple granules within its cytoplasm. In this stain, the nucleus appears pale, with a reddish nucleolus. It is ...

Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal ...

It’s a familiar image, reprinted in countless biology textbooks: an illustration of a typical cell, halved like a grapefruit to reveal its innards. Strands of endoplasmic reticulum encircle a nucleus ...

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair. Instead of choosing between seeing big structures or tiny particles, researchers ...
