New viral tools for mapping brains
(Medical Xpress)—A brain-computer-interphase that is optogenetically-enabled is one of the most fantastic technologies we might envision today. It is likely that its full power could only be realized under the guidance of accurate maps of the brain's activity and connections. Creating these maps—or more likely, these dynamic models—will require tools that have scarcely been described let alone implemented. Among the most tantalizing ideas yet to emerge in this vein are probably what the "Kording-Church DNA tickertapes" which are based on modified DNA polymerases to record activity, and also "Zador neural barcodes" that are based on modified viruses which record connections.

New optimal screening threshold for gestational diabetes in twin pregnancies: Ideal 1-hour 50-g glucose challenge test cutoff ≥135 mg/dl
A common complication, gestational diabetes affects approximately 6-7% of pregnant women. Currently, screening is done in two steps to help identify patients most at risk; however, the suggested levels for additional testing were based on singleton pregnancy data. Now investigators have analyzed data from twin pregnancies and have determined that the optimal first step cutoff for additional screening appears to be a blood sugar level equal to or greater than 135 mg/dL for women carrying twins.
