Researchers have found evidence of nuclear metabolic enzymes for the first time, contributing to our understanding of cancer ...

The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of biology. They carry genetic material, but they cannot make proteins on ...

More than two hundred metabolic enzymes, many of which are normally tasked with producing energy in the mitochondria, are also found sitting directly on top of human DNA, according to a study ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is ...

Cells were long believed to safeguard nuclear contents, releasing them only during cell death. Extracellular DNA was thought ...

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is ...

It’s a familiar image, reprinted in countless biology textbooks: an illustration of a typical cell, halved like a grapefruit to reveal its innards. Strands of endoplasmic reticulum encircle a nucleus ...

Funding for the Department of Homeland Security lapsed on Saturday amid a standoff over restrictions that Democrats have demanded for federal immigration agents. But much of its work continues. By The ...
