There are more well-founded therapy options for the treatment of strokes than ever before. Care has to be reorganized before these innovations are actually used on patients. Experts are discussing just how to do that successfully – from guidelines for the use of thrombectomy procedures all the way…

Just as members of an orchestra need a conductor to stay on tempo, neurons in the brain need well-timed waves of activity to organize memories across time. In the hippocampus--the brain's memory center--temporal ordering of the neural code is important for building a mental map of where you've…

Testing cancers for 'addiction' to a gene that boosts cell growth can pick out patients who may respond to a targeted drug under development, a major new study reports. By measuring the number of copies of just one gene from cancer DNA circulating in the bloodstream, scientists were able to…

Calcium is a key signalling agent in the information networks of life. As calcium ions cannot cross cell membranes directly, the rise and fall of calcium levels within a cell are controlled through a set of proteins known as the Orai. Researchers have discovered a new player in calcium signalling…

A genetic variant in the 5q11 chromosome, which is associated with susceptibility to developing multiple sclerosis, greatly regulates a gene known as ANKRD55, researchers have discovered. Multiple Sclerosis (MS) is a neurological disease, characterized by demyelination and the onset of chronic,…

The ends of heart muscle cell chromosomes rapidly erode after birth, limiting the cells' ability to proliferate and replace damaged heart tissue, research has found. The study suggests potential new interventions to boost the heart's capacity to repair itself after a heart attack.

A benign virus normally found in the skin can lead to a type of rare, lethal skin cancer. Specifically, infection by the Merkel cell polyomavirus can lead to Merkel cell carcinoma in immune-compromised individuals. Researchers have now identified a type of skin cell as the target of the virus in…
