The incorporation of non-natural base pairs into double-stranded DNA, especially those mediated by metal–ligand interactions, offers new opportunities for synthetic DNA materials. The structural implications of such modifications will help guide developments in this area, and a solution structure of a B-type DNA duplex containing consecutive metal-mediated base pairs has now been elucidated.

The isolation of an intermediate species during the self-assembly of a giant molybdenum oxide wheel suggests that a smaller cluster templates the wheel's formation before being evicted.

Specific molecules in the brain can be imaged and used to make a three-dimensional model of the organ.

Key intermediates and their roles in secondary organic aerosol formation from isoprene have been elucidated.

Well-resolved images of small molecules and their motions can be obtained with high-resolution transmission electron microscopy. It has now been shown that this technique can also be used to visualize individual chemical reactions involving the dimerization of fullerenes and metallo-fullerenes trapped inside carbon nanotubes by monitoring how the positions of their atoms change over time.

The bulk properties of materials that lack long-range order have been widely studied, but their local structures remain difficult to elucidate. Now, using scanning tunnelling microscopy, researchers have been able to look more closely at the structural motifs of robust, two-dimensional glassy networks assembled through metal–ligand interactions.

Precise calculations of molecular properties from first-principles set great problems for large systems because their conventional computational cost increases exponentially with size. Quantum computing offers an alternative, and here the H₂ potential energy curve is calculated using the latest photonic quantum computer technology.

A synthetic functional model of the oxygen reduction site in the enzyme cytochrome c oxidase has been used to investigate the effects of hydrogen sulfide on respiration.

Atmospheric organic aerosols from very different sources evolve towards similar characteristics, simplifying the models needed to investigate their effects on climate and air quality.

More predictable chemical patterns have been created by using nanoparticles instead of ions.

The editorial process at Nature Chemistry differs in some important ways from that employed at other chemistry journals.

Embedding platinum nanoparticles in a polymer matrix produces a system that reacts like a homogeneous catalyst, but provides the stability and separation advantages of a heterogeneous one.

Although it may seem counter-intuitive, the attraction between positively charged radical ions offers a new approach to driving controlled motion in molecular machines.

Small-molecule enzyme-inhibitors often display insufficient affinity and selectivity for their targets causing unwanted side effects when used as drugs. Molecularly imprinted polymers prepared using the enzyme as a template could offer a solution.

Bruce C. Gibb wonders why curry is not part of the chemistry curriculum.

Synthetic procedures for making nanoparticles often result in samples that contain a range of different particle sizes. By using hollow self-assembled metal–organic spheres as templates, however, it is possible to make silica nanoparticles with uniform shapes and sizes in a precisely controlled fashion.

Among the wide variety of synthetic processes that chemists have developed, only a few can be carried out under physiological conditions. A condensation reaction that is controlled by the constituents of cells has led to the formation of nanostructures within living cells.
