Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily.

Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules ...

A fleeting DNA fold called i‑DNA can switch cancer‑related genes on and off, revealing a hidden structural weak point that ...

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 ...

Researchers in Japan have identified a striking new way immune cells strip DNA out of dying neighbors, a process they call ...

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health ...

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 ...

"At first, I kind of laughed … But they were serious. I could just see the seriousness in their faces." In this book excerpt, Lise Barnéoud explores the limitations of DNA testing.

Adults whose brains still have strong neuron production seem to have better memory and cognitive function than do those in ...

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

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in ...
