How blood vessels slow down and accelerate tumor growth

Cancer cells have an enormous need for oxygen and nutrients. Therefore, growing tumors rely on the simultaneous growth of capillaries, the fine branching blood vessels that form their supply network. The formation of new ...

The Big Pore Theory could cure chronic pain

Cornell University researchers have produced for the first time an image of P2X7, a receptor associated with chronic pain. Visualizing the shape of the receptor has also allowed them to make a second groundbreaking discovery: ...

Insulin-sensitive fat leads to obesity

SORLA is a protein that influences the balance of metabolic processes in adipose tissue, a particular form of fat. Too much of it makes fat cells overly sensitive to insulin, which leads them to break down less fat. SORLA ...
