Human cells are extremely small and tightly packed – at about 20 micrometers across, roughly one-fifth the width of a human ...

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 ...

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.

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

Scientists mapping the human body at the cellular level keep running into the same surprise: beneath the apparent chaos of tissues and organs, there is a hidden order that looks a lot like pure ...

Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus about one-tenth as wide as a human hair while making sure the all-important ...

Researchers at Colorado State University have determined how to use artificial intelligence to modify antibodies so they act ...

Precise Bio 3D printed a cornea implant from living human cells, and the Rambam Health Care Campus successfully transplanted ...

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 ...

Researchers at the University of Washington and Fred Hutch found that CARD8, an inflammasome sensor, detects HIV-1 in macrophages during cell-to-cell viral transmissions from infected T cells. HIV can ...

The study found that flu viruses need bigger bulges on the cell’s surface to get inside. These bulges are made from actin, a protein that helps shape the cell, and they weren’t stopped by certain ...
