Researchers from the Max Delbrueck Center for Molecular Medicine (MDC) Berlin-Buch, Germany in collaboration with researchers from the Aarhus University in Denmark have found a receptor responsible for inducing neuronal cell death caused by spinal cord injuries, strokes and aging. ...

Researchers from Cornell University have engineered micro-channels within a water-based gel that can act as a vascular system. The system can carry and deliver oxygen, sugar, proteins, and other growth factors to the growing tissue. The scientists designed the system ...

Researchers report that sleep deprivation can double the chances of dying from a cardiovascular event. However, too much sleep appears to be even more dangerous for us, more than doubling the likelihood of dying from other causes. In a research ...

Scientists at Queen’s University in Belfast have developed a novel, more effective way to deliver drugs for the treatment of skin cancer. The scientists demonstrated that a needle-free jet injection of a drug used in the treatment of skin cancer ...

A European consortium has developed a vaccination against the avian H7N1 Influenza. The new vaccination achieved good results in clinical trials and has a high chance of being approved for clinical use. This new vaccine can save human and animal ...

The 2007 Nobel Prize in Physiology or Medicine will be shared by Oliver Smithies from the University of North Carolina at Chapel Hill, USA,, Mario R. Capecchi from the University of Utah and the Howard Hughes Medical Institute Salt Lake ...

Using a computer model, American scientists hypothesize that two strains of HIV are needed in order to cause AIDS. One strain is the fit strain, which is able to spread many copies of itself, and the other is the unfit ...

Insulin, a hormone secreted by the pancreas, controls the level of sugar in the blood. Diabetic people suffer from low levels of insulin production and/or from abnormal resistance to the insulin hormone with inadequate levels of insulin secretion to compensate ...

Scientists in California have discovered a DNA sequence that turns on and off gene expression in the cell. The human genome is a very long molecule composed of repetitions of the four nucleic acids (coded by the letters A, T, ...

Embryonic stem cells are pluripotent cells, cells that can transform and become any other cell in the body, and for this reason they can be used to heal or strengthen any human tissue. However, so far scientists have had difficulties ...
