By targeting and disabling a protein frequently found in melanoma tumors, doctors may be able to make the cancer more vulnerable to chemotherapy, according to a new study. Although this study was done in laboratory rats, a clinical trial applying the same concept to humans has already begun at four comprehensive cancer centers nationwide.

Researchers have developed a simple artificial cell with which to investigate the organization and function of two of the most basic cell components: the cell membrane and the cytoplasm -- the gelatinous fluid that surrounds the structures in living cells. The work could lead to the creation of new drugs that take advantage of properties of cell organization to prevent the development of diseases.

Researchers have shown that an electric shock ranging from 120 to 52,000 volts can cause neurologic and neuropsychological symptoms in humans. Following an electrical injury, some patients may show various emotional and behavioral aftereffects, such as memory loss and symptoms of depression.

Technology that could someday "MapQuest" Mars and other bodies in the solar system is under development. Scientists are developing a new generation of optical/ultraviolet imaging LIDAR detectors that will significantly extend NASA science capabilities for planetary applications by providing 3-D location information for planetary surfaces and a wider range of coverage than the current technology.
