Sub-Cellular Nanosurgery in Live Cells
A femtosecond laser is used to perform "nano" surgery on a living cell. The actin filaments in the cell have been fluorescently labeled using green fluorescent protein (GFP). When a single filament is cut, it retracts, much like a violin string that has broken. This demonstrates that the actin filaments in the cell are under tension, and hence are being "pulled" apart.

Children learn about nanotechnology (MNDaily)
On October 20, 2006, the UMN MRSEC hosted 450 participants from the Minnesota FIRST Lego League “Nanoquest” competition. FIRST Lego League is an organization, which “introduces children around the world to the fun and experience of solving real world problems by applying math, science, and technology”*.

Anisotropic Magnetism in Dilute Magnetic Semiconductors
D. J. Sellmyer and R. Skomski Groups
Magnetocrystalline anisotropy is found in many magnetic materials which means that the energy of a magnet depends on the magnetization direction. This keeps our windshield wipers moving and our toy magnets attached to the fridge. However, on changing the direction of the field that aligns the magnetic moments, the aligned magnetization normally remains nearly unchanged. A strikingly different behavior has been found by researchers at the University of Nebraska MRSEC.

Ballistic Anisotropic Magnetoresistance
E. Tsymbal Group
Anisotropic magnetoresistance (AMR) is the difference in the resistivity of ferromagnetic materials in external magnetic field when the field is applied along or perpendicular to the current. In macroscopic materials the conductance is diffusive (the mean free path of the electron is much smaller than the device dimensions) and AMR is due to spin dependent scattering of impurities. Until recently AMR used to be the primary way of detecting magnetic fields (as in hard-drive read heads).
