Moving cells with light holds medical promise

Scientists at Washington University School of Medicine in St. Louis have shown they can coax cells to move toward a beam of light. The feat is a first step toward manipulating cells to control insulin secretion or heart rate using light.

Researchers engineer 'protein switch' to dissect role of cancer's key players

Researchers at the University of North Carolina at Chapel Hill School of Medicine have 'rationally rewired' some of the cell's smallest components to create proteins that can be switched on or off by command. These 'protein switches' can be used to interrogate the inner workings of each cell, helping scientists uncover the molecular mechanisms of human health and disease.

Adult stem cells isolated from human intestinal tissue

The accomplishment provides a much-needed resource for scientists eager to uncover the true mechanisms of human stem cell biology. It also enables them to explore new tactics to treat inflammatory bowel disease or to ameliorate the side effects of chemotherapy and radiation, which often damage the gut.

DNA: how to unravel the tangle

A chromosome is rarely found in the shape we are used to seeing in biology books, that is to say the typical double rod shape. It is usually 'diluted' in the nucleus and creates a bundle that under the microscope appears as a messy tangle. A research coordinated by the scientists at SISSA of Trieste has now developed and studied a numeric model of the chromosome that supports the experimental data and provides a hypothesis on the bundle's function.
