Faster diagnosis of inherited and lethal nerve disease could advance search for new treatments
Johns Hopkins physicians report success in a small study of a modified skin biopsy that hastens the earlier diagnosis of an inherited and progressively fatal nerve disease and seems to offer a clearer view of the disorder's severity and progression. With a quicker and less invasive way to visualize the hallmark protein clumps of the rare but lethal disease—familial transthyretin amyloidosis—the researchers say they hope to more rapidly advance clinical trials of treatments that may slow the disease and extend patients' lives.

Are the chemicals we encounter every day making us sick?
When her kids were young, Tracey Woodruff, PhD, MPH, knew more than most people about environmental toxics. After all, she was a senior scientist at the Environmental Protection Agency (EPA). But even she never dreamed, as she rocked her children to sleep at night, that the plastic baby bottles she used to feed them contained toxic chemicals that could leach into the warm milk.

Sulforaphane in broccoli sprouts found to improve glucose levels in diabetics
A team of researchers from Sweden, the U.S. and Switzerland has found that treating rat liver cells with a compound called sulforaphane, which is found in cruciferous vegetables, reduced production of glucose. In their paper published in Science Translational Medicine, the group outlines the methods they used to isolate the compound and what they found when testing it with liver cells and in human patients.
