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'.
It turns out that after an appropriate teaching procedure even a relatively simple chemical system can perform non-trivial operations. In their most recent computer simulations researchers have shown that correctly programmed chemical matrices of oscillating droplets can recognize the shape of a sphere with great accuracy.
The new metamaterials can be fabricated in multiple layers to form complex, three-dimensional meta-atoms that reflect more light than shiny gold surfaces, usually considered the ultimate in infrared reflectivity.
