The atmospheric CO growth rate (CGR) variability is largely controlled by tropical temperature fluctuations. The sensitivity of CGR to tropical temperature has strongly increased since 1960, but here we show that this trend has ceased. [...]

Magnetic topological insulators constitute a novel class of materials whose topological surface states (TSSs) coexist with long-range ferromagnetic order, eventually breaking time-reversal symmetry. The subsequent bandgap opening is predicted to co-occur with a distortion of the TSS warped shape from hexagonal to trigonal. [...]

El espectáculo de la conservación. El Parque Nacional de Doñana en El Hombre y la Tierra (1979)
/
Alcalà Lorente, Mònica (Universitat Autònoma de Barcelona) ;
Tabernero, Carlos (Universitat Autònoma de Barcelona)
A finales de la década de los setenta, se emitieron cuatro documentales dedicados al Parque Nacional de Doñana en la serie de Televisión Española El Hombre y la Tierra, dirigida por Félix Rodríguez de la Fuente. [...]
By the end of the 1970s, four documentaries about Doñana National Park were broadcast within the National Spanish Television series Man and the Earth, directed by Félix Rodríguez de la Fuente. Through the account of the Park's life cycle -each chapter matched each one of the year's seasons-, these chapters were a celebration of the struggle to conserve the natural heritage, whose meaning was established in relation to a beautifully-produced representation of both nature and the natural sciences. [...]
