Research from the University of Göttingen in Germany suggests existing data from ultrasound imaging can be used to work backwards to reconstruct the underlying electrical causes of arrhythmias.  A new paper in Nature Photonics from researchers at CU Boulder details impressive improvements in the ability to control the propagation and interaction of light in complex media such as tissue-an area with many potential applications in the medical field.  The new microscopes, known as mesoSPIMs, can image the minute detail of brain tissue down to individual neurons, and can uncover the 3-D anatomy of entire small organs faster than ever before.  A team of researchers from Harvard University and Massachusetts Institute of Technology has found that they could use an optical tweezer array of laser-cooled molecules to observe ground state collisions between individual molecules.  Researchers at the University of Illinois at Urbana-Champaign have replicated one of the most well-known electromagnetic effects in physics, the Hall Effect, using radio waves (photons) instead of electric current (electrons).  A team of researchers from Harvard University and Massachusetts Institute of Technology has found that they could use an optical tweezer array of laser-cooled molecules to observe ground state collisions between individual molecules.  "With optical tweezers, you can capture a single particle in its native state in solution and watch its structural evolution," said Linda Young, Argonne distinguished fellow.  The optical tweezer is revealing new capabilities while helping scientists understand quantum mechanics, the theory that explains nature in terms of subatomic particles.  In the perspective, Gabor and Song collect early examples in electron metamaterials and distil emerging design strategies for electronic control from them.  Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them.
