La misión científica de Herschel terminó el pasado 29 de abril, cuando se agotaron sus reservas de helio. Sin embargo, este leal satélite fue útil hasta el final, sirviendo como plataforma para probar nuevas técnicas de control que normalmente no se pueden comprobar en órbita.Los controladores...

Virginia Tech researchers developed a new microfabrication technique to develop three-dimensional microfluidic devices in polymers. The devices can be used in the analysis of cells and could prove useful in counterterrorism measures and in water and food safety concerns. Fuente :...

When a new species emerges following adaptive changes to its local environment, the process of choosing a mate can help protect the new species' genetic identity and increase the likelihood of its survival. But of the many observable traits in a potential mate, which particular traits does a female...

Industrial palladium-copper catalysts change their structures before they get to work, already during the activation process. As a result, the reaction is catalyzed by a catalyst that is different from the one originally prepared for it. This surprising discovery was made by researchers from the...
