MCB news article on new research from Jeff Lichtman and colleagues, first author Neha Karlupia, describing a method where small samples of human medical biopsies made available at the time of neurosurgery are rapidly preserved and then stained with heavy metals and embedded in a hard resin for connectomic studies.

Jiarui Wang and colleagues in the Kreiman lab share key insights from a study of invasive neurophysiological activity from 48 human subjects to build a map of functional connections in the cerebral cortex at the mesoscale. These results (www.braininteractome.com) can help neurologists to better understand pathology, and neuroscientists to better understand computations in the human brain.

Bruna Paulsen of the Arlotta lab at Harvard, together with colleagues Rogelio Hernandez-Lopez and Laura Peña-Hernandez, describes the outreach work of Science Clubs International, a STEM outreach organization that serves students in eight different countries.
