MIT researchers found that mice with normal DNA repair systems had more retinal degeneration upon exposure to environmental toxic agents than mice lacking a certain DNA repair system. At right, the cross section of the retina from a mouse lacking the repair system is normal. At left, mice with too much DNA repair have greatly reduced numbers of cells in the OPL (outer plexiform layer) and ONL (ou...

The top image shows a mixture of gold nanoparticles. The longer particles are called nanobones, and the smaller are nanocapsules. Bottom left: After the nanoparticles are hit with 800 nanometer wavelength infrared light, the nanocapsules melt and release their payload. Nanobones remain intact. Right: After the nanoparticles are hit with 1100 nanometer wavelength infrared light, the nanobones melt...

Kinesin, a small motor protein found in cells, walks stepwise onÂ microtubules to perform cellular processes. In each step, a powerÂ stroke is generated when two mechanical elements (neck linker, in red, and cover strand, in blue) form a beta-sheet that folds to drive the protein forward.
