Novel imaging techniques are making it possible to study the brain while it’s at work. These new, non-invasive tools – representing significant advances related to positron emission tomography (PET), 3-D microscopy and the use of magnetic fields and nanoparticles to remotely control targeted cells – permit the real-time study of neural activity in unprecedented detail.

Researchers have identified a species of bacteria that uses just two enzymes to break down a tough type of plastic polymer. The findings are published in the 11 March issue of Science.

Many neuroscience data sets have far more information than any laboratory can fully analyze, and researchers must do more to ensure their data are accessible to others, experts said at AAAS.
