Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment ...

Extracellular vesicles (EVs) are nanoscale lipid bilayer particles secreted by cells that mediate intercellular communication ...

Researchers have identified an unexpected mechanism that links age-related stress to the decline of blood-forming stem cells. Instead of triggering cell death, a known signaling pathway subtly ...

Researchers at Oregon Health & Science University have identified a previously unknown system inside cells that works like ...

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic ...

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

Multiple myeloma is the second most common blood cancer in adults. It starts in the white blood cells that are responsible ...

Sometimes I read a paper that literally gives me goosebumps—not because it gave me the answer to a question I’ve been seeking ...

Cancer is a disease that causes abnormal cells to reproduce and spread to other parts of the body, which can result in tumors or damage to the immune system that may become fatal. Healthy cells follow ...

Cancer is often seen as a disease that arises from genetic mutations causing cells to divide uncontrollably and invade other parts of the body. But the spread of cells away from their origins is ...

Cells aren’t as passive as scientists once thought—they actively create internal currents to move proteins quickly and efficiently. These “cellular winds” push materials to the front of the cell, ...
