New results from a prospective study published in the Journal of Clinical Oncology show that patients with a body mass index in the obese range live on average two to three months less after a pancreatic cancer diagnosis, compared with healthy weight patients, even after adjusting for factors that...

In a paper published last month in the SIAM Journal on Applied Mathematics, authors Carmen Calvo-Garrido, Andrea Pascucci, and Carlos Vazquez present a partial differential equation model governing the value of defined pension plans including the option for early retirement. Fuente :...

Nitrogen fertilizer applied to crops lingers in the soil and leaks out as nitrate for decades towards groundwater -- "much longer than previously thought," scientists in France and at the University of Calgary say in a new study.Thirty years after synthetic nitrogen fertilizer had been applied to...

Widespread vaccination of adolescents for pertussis was associated with lower rates of infant hospitalizations for the respiratory infection than would have been expected had teens not been inoculated according to new research in Pediatrics. Fuente :...

Older adults are often encouraged to stay active and engaged to keep their minds sharp, that they have to "use it or lose it." But new research indicates that only certain activities -- learning a mentally demanding skill like photography, for instance -- are likely to improve cognitive...

Predicting whether consumers will purchase organic or conventional food is a multimillion dollar gamble within the food sector. A novel paper by Washington State University College of Business researchers will help advertisers more effectively target the fast-growing organic food market. Fuente :...

Hereditary high blood cholesterol leads to premature heart disease. It is overlooked and untreated virtually worldwide -- including in Europe. This is a major problem as the disease is dangerous for health. However, this disease is easy to diagnose and treat, according to the conclusion of a...

A new study is the first to identify a biological clock able to gauge the age of most human tissues. Some parts of the anatomy, like a woman's breasts, age faster than the rest of the body. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/E...

What happens when the brain recognizes an error? A new study shows that the brains of humans and rats adapt in a similar way to errors by using low-frequency brainwaves in the medial frontal cortex to synchronize neurons in the motor cortex. The finding could be important in studies of mental...

Scientists have created a cucumber genomic variation map that includes about 3.6 million variants revealed by deep resequencing of 115 cucumbers worldwide. This work provides new insights for understanding the genetic basis of domestication and diversity of this important crop, and provides...

Researchers are using the fruit fly to discover how the brain integrates multiple signals to identify one unique smell. It's work that has broader implication for how flies -- and ultimately, people -- learn. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/p...

Time is a huge impediment when it comes to working together to halt the effects of climate change, new research suggests. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/1...

In a biological quirk that promises to provide researchers with a new approach for studying and potentially treating Fragile X syndrome, scientists have shown that knocking out a gene important for messenger RNA translation in neurons restores memory deficits and reduces behavioral symptoms in a...

Scientists have found a novel and unexpected molecular switch that could become a key to slowing some of the ravages of getting older as it prompts blood stem cells to age. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/I...

Cell biologists have discovered that message-relaying proteins inside cells always initiate the cellular projections that act as hands to help cells "crawl." The messenger protein network was known to be required for directional movement but scientists now know that it can self-activate...

Scientists have developed a general approach for combining different types of nanoparticles to produce large-scale composite materials. The technique opens many opportunities for mixing and matching particles with different magnetic, optical, or chemical properties to form new, multifunctional...

Researchers used suction to learn that individual “molecular muscles” within cells respond to different types of force, a finding that may explain how cells “feel” the environment and appropriately adapt their shapes and activities. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/1...

Para consultar el tiempo que hará mañana basta con realizar una búsqueda simple en Internet que devolverá múltiples resultados. No obstante cabe preguntarse cuál será el más preciso. Pero, ¿y si, además, por padecer algún tipo de alergia, se quiere conocer la concentración de polen o la...

Volete sapere che tempo farà domani? Una semplice ricerca su internet vi fornirà una previsione o, con più probabilità, molte previsioni. Come fare per sapere qual è più giusta? E se volete conoscere anche la conta pollinica perché siete allergici o i livelli di inquinamento perché vi preoccupate...

Pragniecie Państwo dowiedzieć się, jaka jutro będzie pogoda? W internecie z łatwością można znaleźć prognozę, a nawet kilka jej wariantów. Skąd jednak wiedzieć, która z prognoz jest dokładna? Co więcej, co jeśli chcielibyście Państwo sprawdzić stężenie pyłków w powietrzu, gdyż np. cierpicie z...

Voulez-vous savoir le temps qu'il fera demain? Une simple recherche en ligne vous permet de trouver la, ou plutôt les prévisions que vous recherchez. Mais comment savoir quelle est la plus précise? Et peut-être souhaitez-vous également connaître la densité pollinique en raison de votre allergie, ou...

En la década de 1960, el gobierno de Cuba consideró que el almacenamiento de agua dulce para enfrentar sequías y huracanes era un asunto de seguridad nacional, y comenzó a represar ríos. Esa política tiene hoy una víctima impensada: los manglares, que ya no pueden atajar el avance de las marejadas....

Científicos del Centro Nacional de Investigaciones Oncológicas (CNIO), en España, han descubierto mediante ratones manipulados genéticamente que las dos variantes de Pds5 – una proteína relacionada con las cohesinas, encargadas de unir las dos copias de cada cromosoma– no son... Fuente :...

Un equipo español de estudiantes ha participado con éxito este mes en la campaña educativa REXUS/BEXUS del Centro Aeroespacial Alemán (DLR) y el Comité Espacial Nacional de Suecia, en colaboración con la Agencia Espacial Europea (ESA), en la que se lanzan experimentos a la estratosfera en...
