Super-sharp Images of the Brain
To explore the most intricate structures of the brain in order to decipher how it functions Stefan Hell’s team of researchers at the Max Planck Institute for Biophysical Chemistry in Göttingen has made a significant step closer to this goal. Using the STED microscopy developed by Hell, the scientists have, for the first time, managed to record detailed live images inside the brain of a living mouse. Captured in the previously impossible resolution of less than 70 nanometers, these images have made the minute structures visible which allow nerve cells to communicate with each other. This application of STED microscopy opens up numerous new possibilities for neuroscientists to decode fundamental processes in the brain. (Science, February 3, 2012)

Real-time MRI of a human heart (2-chamber view) at 2.0 mm spatial resolution and 22 ms temporal resolution. The T1-weighted images were acquired with an RF-spoiled radial FLASH CMR sequence (TR/TE = 2.0/1.3 ms, flip angle 8°, 11 spokes) at 2.0 mm resolution, 8 mm section thickness, and 22 ms acquisition time without ECG or respiratory gating. Image reconstruction was achieved by regularized nonlinear inversion. (See: doi:10.1186/1532-429X-12-39 http://www.jcmr-online.com/content/12/1/39)
