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 ...

This article was originally featured on Knowable Magazine. More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the ...

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 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, ...

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 ...

In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells—one ...

The cochlea is the spiral-shaped structure within the inner ear responsible for our sense of hearing. To fully understand hearing functions and open the door to new hearing loss treatments, scientists ...

Initially, cells are dissociated from liver tissues into single-cell suspensions using in vivo enzymatic perfusion or ex vivo digestion methods. The cells of interest are then enriched from the ...
