Children as young as three recognise ‘cuteness’ in faces of people and animals - 21/07/2014 / Leido 196 veces/ Comentarios 0

Children as young as three are able to recognise the same ‘cute’ infantile facial features in humans and animals which encourage caregiving behaviour in adults, new research has shown. Fuente : http://www.alphagalileo.org/ViewItem.aspx?ItemId=1...

La conducta impulsiva de los niños se relaciona con su conectividad cerebral - 21/07/2014 / Leido 160 veces/ Comentarios 0

Investigadores de la Universidad de Murcia han estudiado los cambios en el cerebro que se asocian con la impulsividad, un rasgo de la personalidad que provoca dificultades para inhibir la respuesta ante un estímulo y predispone a reacciones no planeadas sin tener en cuenta sus consecuencias...

Our daily bread – new insights into the bread wheat genome and its significance for the global food supply - 21/07/2014 / Leido 176 veces/ Comentarios 0

Neuherberg, 21.07.2014. Scientists at the Helmholtz Zentrum München (HMGU) have conducted research in frame of the International Wheat Genome Sequencing Initiative. They gained new insights into the composition and structure of the wheat genome and the complex interplay of genes that form the basis for regulating a polyploid*...

Genetic risk for autism stems mostly from common genes - 21/07/2014 / Leido 285 veces/ Comentarios 0

Using new statistical tools, scientists have discovered that most of the genetic risk for autism comes from versions of genes that are common in the population rather than from rare variants or spontaneous glitches. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/z...

Size and age of plants impact their productivity more than climate - 21/07/2014 / Leido 284 veces/ Comentarios 0

The size and age of plants has more of an impact on their productivity than temperature and precipitation, according to a landmark study. They show that variation in terrestrial ecosystems is characterized by a common mathematical relationship but that climate plays a relatively minor direct role. The results have important...

Tiny laser sensor heightens bomb detection sensitivity - 21/07/2014 / Leido 253 veces/ Comentarios 0

Researchers have created a plasmon laser detector that can sniff out tiny traces of airborne molecules of explosives. The sensor detected both DNT and ammonium nitrate at concentrations below one part per billion. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/5...

New technique maps life's effects on our DNA: Powerful single-cell technique to study environmental effects on DNA - 21/07/2014 / Leido 211 veces/ Comentarios 0

Genetic cause of common breast tumors found - 21/07/2014 / Leido 207 veces/ Comentarios 0

A major breakthrough in understanding the molecular basis of fibroadenoma, one of the most common breast tumors diagnosed in women, has been made by a multidisciplinary team of scientists. The team used advanced DNA sequencing technologies to identify a critical gene called MED12 that was repeatedly disrupted in nearly 60...

2014-07-21 | Expertos del INTA desarrollarán una “Wikipedia” de los suelos argentinos - 21/07/2014 / Leido 2 veces/ Comentarios 0

El proyecto SISINTA estará disponible como material de consulta a fines del 2015. Para los menos expertos, contará con un buscador personalizado para acceder por provincia o departamento, mientras que los usuarios más avanzados podrán consultar por antigüedad o material con el que están hechos los suelos. Además, brindará un...
