Researchers have been searching for decades for a way to mend damage to the spinal cord, an injury that can lead to life-long paralysis. Even the smallest of breaks in these crucial central nerve fibers can result in the loss of leg, arm and other bodily functions...
Researchers pin down a pathway coming between mammals and the ability to regenerate tissue salamander-style.
People whose brains are too symmetrical are at risk for cognitive problems
RAD-AID, Project Hope and Philips Healthcare team up to assess the ability of communities in western China and northern India to use CT scans, MRIs and other imaging equipment to improve health care...

A rush of new research has found evidence that some RNA viruses made their way into vertebrate genomes millions of years ago
Brain scans illuminate the internal connection among the neurotransmitter, impulsiveness and addiction
A voyage through the human body is no longer mere fantasy. Tiny devices may soon perform surgery, administer drugs and help diagnose disease
The life-giving sun can be quite rough on genetic material. Most organisms, including plants and many animals, are equipped with a special enzyme in their cells that is quick to repair DNA damage wrought by the sun's ultraviolet (UV) rays...
Curious differences in gene expression between reprogrammed adult stem cells, called induced pluripotent stem cells (iPS cells), and the embryonic stem cells that the former are designed to mimic might now be explained by a new discovery about just how much information a "reprogrammed" adult stem cell retains...
A vaginal microbicide can cut HIV infection rates by 39 percent in women, researchers announced Monday. And female study participants who inserted the gel as directed reduced their chances of contracting HIV by more than half (54 percent)...
Former Vice President Dick Cheney's announcement this week that he has been implanted with a left ventricular assist device (LVAD) to aid his ailing heart highlights one of several technologies available to people suffering from heart failure...
Proton-pump inhibitors such as Nexium, Prevacid and Protonix treat acid reflux, but their use as a preventative to bleeding can lead to problems
A complex of laboratories and data centers under construction in Kazakhstan is attracting tech entrepreneurs and, more importantly, the money to deliver the goods

After years of false starts, a new generation of DNA vaccines and medicines for HIV, influenza and other stubborn illnesses is now in clinical trials
Pathogens with added genes from Arctic bacteria could serve as vaccines that elicit an immune response before getting cooked in our warm bodies. Cynthia Graber reports
A new artificial heart ventricular pump uses a power driver shrunken to 3 percent of its original weight, yet is able to generate enough energy to maintain optimum pumping capacity
The Information Age has patients tuned in and geared up to try alternative and off-label therapies on their own terms, forcing doctors and scientists to change the game
Researchers have recently found a new reason for doctors to listen to the heart: Certain heart rhythms may provide critical information about the health of our kidneys.Daniel Brotman, professor of medicine at Johns Hopkins University, and colleagues analyzed data from 13,241 individuals enrolled in the Atherosclerosis Risk in Communities (ARIC) Study...
