Engineers at the University of California at San Diego have come up with a way to help accelerate bone growth through the use of nanotubes and stem cells.
Researchers from Northwestern University's Feinberg School of Medicine appear to have reversed the neurological dysfunction of early-stage multiple sclerosis patients by transplanting their own immune stem cells into their bodies and thereby "resetting" their immune systems.
Scientists at Heriot-Watt University have found that short, intensive periods of exercise – involving as little as seven minutes per week – can significantly reduce the chances of contracting diabetes.
For patients with a particularly aggressive form of skin cancer – malignant melanoma – stress, including that which comes from simply hearing that diagnosis, might amplify the progression of their disease.

Scientists have known for more than 200 years that vision begins with a series of chemical reactions when light strikes the retina, but the specific chemical processes have largely been a mystery.
Two common strains of methicillin-resistant Staphylococcus aureus, commonly known as MRSA, were virtually eradicated in the laboratory by exposing them to a wavelength of blue light.
A key phase in the repair process of damaged human DNA has been observed and visually recorded by a team of researchers at the University of California, Davis. The recordings provide new information about the role played by a protein known as Rad51, which is linked to breast cancer, in this complex and critical process.
A new study has found that transplantation of stem cells from the lining of the spinal cord, called ependymal stem cells, reverses paralysis associated with spinal cord injuries in laboratory tests.
Mice with increased levels of a natural brain chemical don't gain weight when fed a high-fat diet, researchers at UT Southwestern Medical Center have found.
People who buy fake internet drugs could be risking their lives and supporting terrorism, according to an editorial in the February issue of IJCP, the International Journal of Clinical Practice.
Diabetics have a significantly greater risk of dementia, both Alzheimer's disease -- the most common form of dementia -- and other dementia, reveals important new data from an ongoing study of twins.
Medicare patients treated at top-rated hospitals nationwide across the most common Medicare diagnoses and procedures are 27 percent less likely to die, on average, than those admitted to all other hospitals.
Astronauts spending months in space lose significant bone strength, making them increasingly at risk for fractures later in life.
