A team of chemists has created self-assembled, three-dimensional DNA crystals that can bind a separate, dye-bearing strand - a breakthrough that enhances the functionality of these tiny building blocks.
Scientists have used electron cryomicroscopy to show that a small difference of only several amino acids can have a large impact on flagella function. The study gives new insight on the construction of synthetic nanomachines.
By carefully combining multiple structures, metamaterials can exhibit properties that don't naturally exist. Engineers now have a new, simpler way of making them, using a concept dubbed 'photonic doping'.
