Researchers describe a new method for designing geometric forms built from DNA. They present a novel variant on a technique known as DNA origami, in which the base-pairing properties of DNA are exploited for the construction of tiny structures in 2 and 3 dimensions.
The review is one part of the proceedings of a 2015 workshop organized by the PETA International Science Consortium, at which scientists discussed recommendations for designing an in vitro approach to assessing the toxicity of nanomaterials in the human lung.
This idea is part of the evolving science of precision agriculture, in which farmers use technology to target their use of water, fertilizer and other inputs. Precision farming makes agriculture more sustainable because it reduces waste.
