Headaches may act like tiny transient strokes

Migraines may be doing more than causing people skull-splitting pain. Scientists have found evidence that the headaches may also be acting like tiny transient strokes, leaving parts of the brain starved for oxygen and altering the brain in significant ways.

New approach to cystic fibrosis treatment

Researchers at the University of Pennsylvania School of Medicine have discovered that an enzyme produced by lung-infecting bacteria further shuts down a protein that is defective in cystic fibrosis patients.

First measurement of a cellular heartbeat

Researchers have made a breakthrough by detecting the electrical equivalent of a living cell's last gasp. The work takes them a step closer to both seeing the 'heartbeat' of a living cell and a new way to test drugs.

Scientists alter electrical properties of cells inducing regeneration

Scientists at Forsyth may have moved one step closer to regenerating human spinal cord tissue by artificially inducing a frog tadpole to re-grow its tail at a stage in its development when it is normally impossible. Using a variety of methods including a kind of gene therapy, the scientists altered the electrical properties of cells thus inducing regeneration.

Link between growth of blood vessels critical to spread of cancer and copper in our bodies

Growing new blood vessels from existing ones - a process called angiogenesis - is important in growth, development and wound healing. But it also enables the spread of tumors throughout the body, so researchers have been scrambling for ways to stop angiogenesis in the fight against cancer.

Irregular heartbeat linked to genetic mutation

Every day for 10 years, a seemingly heart-healthy 53-year-old woman experienced rapid and irregular heartbeats. She had no personal or family history of hypertension or hyperthyroidism. She did not suffer from myocardial or coronary artery disease, or any abnormalities of the heart as best doctors and medical science could determine.

Sharper MRI's

Magnetic resonance imaging, or MRI, has revolutionized health care, providing doctors with a highly accurate, non-invasive tool for diagnosing cancer, injuries and other maladies within the human body. Now, a Florida State University researcher has collaborated in a research project that could lead to ways of producing even sharper medical images.
