Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their ...

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

In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would ...

Ocean pollution is quietly draining energy from seabirds’ cells, as mercury and forever chemicals disrupt mitochondria even ...

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 ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes.

Cells shrink a major internal structure as they age. New research shows this downsizing is deliberate—and linked to longer lifespan.

Kris Burkewitz, assistant professor of cell and developmental biology at Vanderbilt University, describes a new way by which cells adapt to the aging process: by actively remodeling the endoplasmic ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

A fast-aging fish is giving scientists a rare, accelerated look at how kidneys grow old—and how a common drug may slow that ...

The year 2022 has been declared by Pedro Sanchez, President of Spain, as the Year of Ramon y Cajal on the 170th anniversary ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
