Ballaststoffe schützen vor Asthma - 06/01/2014

Die westliche Ernährungsweise hat wohl mehr mit der grassierenden Asthma-Epidemie zu tun als bisher angenommen, denn die Entwicklung von Asthma hängt von der Menge konsumierter Früchte und Gemüse ab. Darmbakterien fermentieren die darin enthaltenen Nahrungsfasern, dadurch gelangen Fettsäuren ins...

Dietary fibres protect against asthma - 06/01/2014

The Western diet probably has more to do with the asthma epidemic than has been assumed so far because developing asthma is related to the amount of fruit and vegetables consumed. Gut bacteria ferment the dietary fibres contained in them and fatty acids enter the blood as a result, influencing the...

Les fibres alimentaires protègent contre l'asthme - 06/01/2014

Le régime alimentaire occidental a probablement plus de responsabilité dans l'actuelle épidémie d'asthme qu'on ne le supposait jusqu'ici. En effet, le développement de l'asthme dépend de la quantité de fruits et de légumes consommés. Les bactéries intestinales fermentent les fibres alimentaires qui...

Conflicto por la tierra en uno de los mayores tugurios de África - 06/01/2014

La controversia sobre la propiedad de la tierra en Kibera, un asentamiento informal de esta capital y uno  de los mayores de su tipo en toda África, podría desembocar en actos de violencia en su población estimada en un millón de personas. Los nubios que viven allí desde hace más de 100 años...

La compleja agenda de política exterior para Obama en 2014 - 06/01/2014

Si el presidente de Estados Unidos, Barack Obama, concibiera sus perspectivas de política exterior para 2014 como algún popular videojuego infantil, las “serpientes” que tendría que sortear superarían en mucho a las “escaleras” que lo impulsarían al éxito. Como ocurre desde que asumió el cargo,...

Worker wasps grow visual brains, queens stay in the dark - 06/01/2014

A queen in a paperwasp colony largely stays in the dark. The worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new Drexel University study indicates that the brain regions involved in sensory perception also develop differently in these castes, according to the...

Babbling babies -- responding to one-on-one 'baby talk' -- master more words - 06/01/2014

Common advice to new parents is that the more words babies hear the faster their vocabulary grows. Now new findings show that what spurs early language development isn't so much the quantity of words as the style of speech and social context in which speech occurs.
