Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these ...

Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence—a biological process in which aging cells change how they function—is associated with human brain ...

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

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

Researchers examined anatomy of neurons from humans, mice and fruit flies. They discovered that the cellular structure of the brain is at a critical point, poised between two phases. New insights ...

As we age, our cells don’t just wear down—they reorganize. Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while ...

Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles ...

In a recent study published in the journal Nature, a large team of researchers from the United States (U.S.) used single-cell ribonucleic acid (RNA) sequencing combined with high-resolution ...
