UCLA imaging system could help reveal 'miscommunications' in autism, schizophrenia

Some disorders of the brain are obvious - the massive death of brain cells after a stroke, the explosion in the growth of cells that marks a tumor. Other disorders, such as autism, schizophrenia and mental retardation show no physical signs of damage and are believed to be caused by problems in how brain cells communicate with one another.

Removal of ZIP proteins from hippocampus cell protects them from injury

Researchers in the Blue Bird Circle Developmental Neurogenetics Laboratory in the department of neurology at Baylor College of Medicine have discovered that zinc enters cells through specialized protein gates known as ZIP transporters, and removing these ZIP proteins from cells in the hippocampus significantly protects them from injury.

Researchers develop high-resolution technology to visualize individual virus particles

In the war against infectious disease, identifying the culprit is half the battle. Now, research professor Shaopeng Wang and his colleagues from the Biodesign Institute at Arizona State University, describe a new method for visualizing individual virus particles. Their research opens the door to a more detailed understanding of these minute pathogens, and may further the study of a broad range of micro- and nanoscale phenomena.

Scientists develop new imaging technique to create three-dimensional images of melanoma

Melanoma is one of the less common types of skin cancer but it accounts for the majority of the skin cancer deaths (about 75 percent).The five-year survival rate for early stage melanoma is very high (98 percent), but the rate drops precipitously if the cancer is detected late or there is recurrence.So a great deal rides on the accuracy of the initial surgery, where the goal is to remove as little tissue as possible while obtaining "clean margins" all around the tumor.So far no imaging technique has been up to the task of defining the melanoma's boundaries accurately enough to guide surgery.Instead surgeons tend to cut well beyond the visible margins of the lesion in order to be certain they remove all the malignant tissue.Two scientists at Washington University in St. Louis have developed technologies that together promise to solve this difficult problem.
