Artículo:: Pulsed electron paramagnetic resonance spectroscopy powered by a free-electron laser
Autor:: S. Takahashi, L.-C. Brunel, D. T. Edwards, J. van Tol, G. Ramian+ et al.
Resumen:: A free-electron laser is used to power a pulsed electron paramagnetic resonance spectrometer at 240 GHz, demonstrating a range of experimental possibilities such as the manipulation of spin-1/2 systems with 6-ns pulses and the measurement of ultrashort decoherence times.

Artículo:: High-performance bulk thermoelectrics with all-scale hierarchical architectures
Autor:: Kanishka Biswas, Jiaqing He, Ivan D. Blum, Chun-I Wu, Timothy P. Hogan+ et al.
Resumen:: Controlling the structure of thermoelectric materials on all length scales (atomic, nanoscale and mesoscale) relevant for phonon scattering makes it possible to increase the dimensionless figure of merit to more than two, which could allow for the recovery of a significant fraction of waste heat with which to produce electricity.

Artículo:: Oceanic nitrogen reservoir regulated by plankton diversity and ocean circulation
Autor:: Thomas Weber & Curtis Deutsch
Resumen:: Here, the feedback between marine nitrogen fixation and denitrification is shown to yield an oceanic nitrate deficit more than double its observed value in a model with realistic ocean circulation; this discrepancy can be resolved by accounting for diversity in the metabolic N:P requirements of plankton.

Artículo:: Afternoon rain more likely over drier soils
Autor:: Christopher M. Taylor, Richard A. M. de Jeu, Françoise Guichard, Phil P. Harris & Wouter A. Dorigo
Resumen:: Analysis of observations on six continents reveals a global preference for afternoon rain to fall on locally drier soils—contrary to the predictions of large-scale climate models, and suggesting that such models may exaggerate the occurrence of droughts.

Artículo:: Spontaneous giving and calculated greed
Autor:: David G. Rand, Joshua D. Greene & Martin A. Nowak
Resumen:: Economic games are used to investigate the cognitive mechanisms underlying cooperative behaviour, and show that intuition supports cooperation in social dilemmas, whereas reflection can undermine these cooperative impulses.
