For the first time, clumps of human cells called organoids were fully integrated with the brains of rats—and influenced their ...

The human body has always been crowded with microscopic passengers, from bacteria to viruses and fungi. Over the past two ...

Human cells are extremely small and tightly packed – at about 20 micrometers across, ...

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 ...

Researchers find obelisks, mysterious RNA molecules in human bacteria that challenge our understanding of viruses and ...

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.

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

Researchers at Colorado State University have determined how to use artificial intelligence to modify antibodies so they act as lightbulbs, enabling scientists to better see inside living cells to ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in diseases Katarina Zimmer, Knowable Magazine Innovative techniques are helping ...
