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 ...

The sunlight-collecting organelles known as chloroplasts solve a packing problem: how to optimize photosynthesis without sustaining damage from dangerously intense rays. Living on light is a dangerous ...

Collagen, the protein that builds skin, bones, tendons and organs, exists inside cells as a liquidlike droplet rather than the long, rigid rod seen in textbooks over the last half-century, according ...

Living cells cool much slower than our current understanding of heat conduction can explain, according to new research from the University of Tokyo. Researchers used two techniques - high-speed ...

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 ...
