A set of new stem cell lines will make it possible for researchers to explore ten different genetic disorders—including muscular dystrophy, juvenile diabetes, and Parkinson's disease—in a variety of cell and tissue types as they develop in laboratory cultures. Researchers led by Howard Hughes Medical Institute investigator George Q. Daley have converted cells from individuals with the diseases into stem cells with the same genetic errors.

A promising new technique has been developed that will enable more accurate non-invasive positron emission tomography (PET) imaging of new cells injected into the body, according to researchers at SNM's 55th Annual Meeting. The new technique, which involves engineering antibody fragments to act as reporter genes—or markers that signal cells of interest for PET imaging purposes—could significantly advance the study of genetically engineered cells to treat diseases.

A study at Rush University Medical Center in Chicago published this week in the online version of Biophysical Journal proposes that bubbles may control the opening and closing of ion channels. This new understanding of the channels that control much of life in health and disease provides a vital piece of the molecular puzzle.

The diagnosis has come in, and it’s not good. Worse, the patient has to choose from treatment options that are sometimes contradictory and risky. None of them promises complete success. How do patients make an informed decision, choosing the very best treatment for their own healthcare?
