Exciton condensation and perfect Coulomb drag

- Resumen:
An electronic current flowing in one conductor can induce a drag current in another spatially separated conductor by means of Coulomb interactions; when these interactions are sufficiently strong the currents become equal and the drag therefore ‘perfect’, as shown here for a bilayer two-dimensional electron system.

Room-temperature ferroelectricity in supramolecular networks of charge-transfer complexes
- Autor:
Alok S. Tayi, et al.
- Resumen:
Organic ferroelectrics with switchable electrical polarization would be an attractive prospect for applications if their Curie temperature—below which these materials display ferroelectric behaviour—could be raised to room temperature or above; this goal has now been achieved with a family of organic materials characterized by a supramolecular structural motif.

Long-term decline of global atmospheric ethane concentrations and implications for methane
- Autor:
Isobel J. Simpson, et al.
- Resumen:
The longest continuous record of global atmospheric ethane levels is presented, showing that global ethane emission rates decreased by 21 per cent from 1984 to 2010, probably owing to decreased venting and flaring of natural gas in oil fields; decreased venting and flaring also account for at least 30 to 70 per cent of the decrease in methane emissions over the same period.

Contrasting patterns of early twenty-first-century glacier mass change in the Himalayas
- Autor:
Andreas Kääb, Etienne Berthier, Christopher Nuth, Julie Gardelle & Yves Arnaud
- Resumen:
Data for the Hindu Kush–Karakoram–Himalaya region from satellite laser altimetry and a global elevation model shows that glacier thinning varied by an order of magnitude across the region, with surface debris not seeming to provide effective insulation, and that the melting ice added several per cent to the annual discharge of the mountain rivers.

Mutations in the profilin 1 gene cause familial amyotrophic lateral sclerosis
- Autor:
Chi-Hong Wu, et al.
- Resumen:
Mutations in the profilin 1 (PFN1) gene, which is crucial for the conversion of monomeric to filamentous actin, can cause familial amyotrophic lateral sclerosis, suggesting that alterations in cytoskeletal pathways contribute to disease pathogenesis.
