Even after decades of research, biologists are still uncovering surprises about the human body. A team of researchers from the University of Virginia and the National Institutes of Health (NIH) have ...

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 ...

RAB7A plays a central role in the final stages of autophagy, facilitating autophagosome-lysosome fusion, lysosome positioning, and cargo degradation. Its activation by guanine nucleotide exchange ...

Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence—a biological process in ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

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.
