    The transformation of petroleum-derived feedstocks into useful chemicals often requires controllable cleavage of C–H or C–C bonds. There are many examples of achieving this through the oxidative addition of C–H bonds to metal centres, but analogous transformations of C–C bonds are rare. Here, using a tungsten centre and exploiting the formation of an unusual chelating ligand, a strong C–C bond is cleaved; other metal centres with suitable ancillary ligands could perform the same function.

    As a rule of thumb, carbon–carbon bonds are not easily broken. But a tungsten complex has been found to break a particularly strong carbon–carbon bond, opening up fresh opportunities for organic synthesis.

    In the search to reduce our dependency on fossil-fuel energy, new plastic materials that are less dependent on petroleum are being developed, with water-based gels — hydrogels — representing one possible solution. Here, a mixture of water, 3% clay and a tiny amount of a special organic binder is shown to form a transparent hydrogel that can be moulded into shape-persistent, free-standing objects and that rapidly and completely self-heals when damaged.

    Springtime ozone levels in the lower atmosphere over western North America are rising. The source of this pollution may be Asia, a finding that reaffirms the need for international air-quality control.

    Like any other field, research on climate change has some fundamental gaps, although not the ones typically claimed by sceptics. Quirin Schiermeier takes a hard look at some of the biggest problem areas.

    Phytochromes regulate numerous photoresponses in plants and microorganisms through their ability to photointerconvert between a red-light-absorbing, ground state (Pf) and a far-red-light-absorbing, photoactivated state (Pfr). The structures of several phytochromes as Pf have been determined previously; here, the three-dimensional solution structure of the bilin-binding domain as Pfr is described. The results shed light on the structural basis for photoconversion to the activated Pfr form.
