Some scientific results are hard to spot, especially in genetic research. Often scientists are unable to physically see if the gene they inserted into a cell has produced the desired trait. To overcome this problem researchers use various genetic markers that contain pieces of foreign DNA that cause cells to, for example, glow when exposed to ultraviolet light.

When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animal's heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology.

Two Ottawa researchers have been awarded a $2.4-million grant for their work in fighting multiple sclerosis, a chronic and often disabling disease of the brain and spinal cord.

A diagnosis of type I diabetes means a life sentence of medical follow-up. While treatments have become simpler and less restrictive in recent years, they are still a burden, especially for young patients. The latest study published in the journal Nature by Dr. Constantin Polychronakos, provides hope that this situation will evolve in the long term toward a cure for this disease.

Forsyth Institute scientists have discovered an important mechanism for controlling the behavior of adult stem cells. Research with the flatworm, planaria, found a novel role for the proteins involved in cell-to-cell communication.
03 августа 2007
A report from researchers at Children's Hospital Boston and the Harvard Stem Cell Institute sheds new light on a now-discredited Korean embryonic stem cell line, setting the historical record straight and also establishing a much-needed set of standards for characterizing human embryonic stem cells.
03 августа 2007
A team of scientists from the University of Wisconsin-Madison has shown it is possible to rescue the dying neurons characteristic of amyotrophic lateral sclerosis
02 августа 2007
A special type of cell found in the eye has been found to be very important in regenerating the retina in zebrafish and restoring vision even after extensive damage.
