Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025, and a previously unknown cellular structure that could be vital to our ...

Most cells in the human body exist in complex three-dimensional environments, yet they are still commonly studied on flat plastic dishes. These two-dimensional cultures distort cell behavior, limiting ...

Scientists have crossed a startling new frontier in bioengineering: they can now fabricate intricate three-dimensional objects inside living cells. Instead of sculpting tissue from the outside, they ...

Scientists can peer into cells to get a limited view of their activity using microscopes and other tools. However, cells and the molecular events within them are dynamic, and developmental processes, ...

In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells—one of the few brain cell types that continue to be produced in the adult ...

Our body's "blood factory" consists of specialized tissue made up of bone cells, blood vessels, nerves and other cell types. Now, researchers have succeeded for the first time in recreating this ...
