Various regions of the brain often work independently. But what happens when two regions must cooperate to accomplish a task? What mechanism allows them to communicate in order to cooperate, yet avoid interfering with one another when they work alone? Stanford scientists reveal a previously unknown...

Researchers at the University of California, San Diego School of Medicine have identified a protein critical to hematopoietic stem cell function and blood formation. The finding has potential as a new target for treating leukemia because cancer stem cells rely upon the same protein to regulate and...

Scientists have identified, for the first time, a way in which the decreased functional connectivity seen in the brain of many people with autism can come about: it can be caused by cells called microglia failing to trim connections between neurons, researchers from the European Molecular Biology...

Nueve socios europeos han comenzado en Milán a trabajar en el proyecto “Babylux”, cuyo objetivo es el de controlar con un alto nivel de precisión el estado cerebral clínico de los bebés prematuros. BabyLux -en el que participa la española Loop Business Innovation junto al Politécnico di Milano,......

Un trabajo conjunto entre los equipos de Miquel Coll en el Instituto de Investigación Biomédica (IRB) y el Instituto de Biología Molecular del CSIC, en Barcelona (España), y Dolf Weijers de la Universidad de Wageningen, en Holanda, han descubierto el misterio de cómo unas hormonas de plantas,...

Researchers have studied MS measurement tools for their effectiveness in predicting employment status. They compared the Expanded Disability Status Scale, the Multiple Sclerosis Functional Composite, the Paced Auditory Serial Addition Task, and the Symbol Digit Modalities Test, and found the SDMT...

A genetic study of adult twins and a community-based study of adolescents both report novel links between sleep duration and depression. A study of 1,788 twins is the first to demonstrate a gene by environment interaction between self-reported habitual sleep duration and depressive symptoms....

Behind every “Top 100” list are a generous sprinkling of personal bias and subjective decisions. Lacking the tools to calculate how factors like median home prices and crime rates actually affect the “best places to live,” the public must take experts’ analysis at face value. Fuente :...

Disruptive clumps of mutated protein are often blamed for clogging cells and interfering with brain function in patients with the neurodegenerative diseases known as spinocerebellar ataxias. But a new study in fruit flies suggests that for at least one of these diseases, the defective proteins may...

El peso de una salida negociada a la guerra civil de Siria recae ahora en las potencias, Estados Unidos y Rusia, que actúan tras bambalinas desde que se desató hace tres años el conflicto armado entre el régimen de Bashar al Assad y la oposición rebelde. Así ocurrirá por lo menos durante los...

La capital de Yemen, Sana’a, tiene más de 2.500 años de antigüedad, lo que la hace una de las ciudades habitadas más antiguas del mundo. Pero está viviendo tiempo prestado. Más de la mitad de los cuatro millones de habitantes que tendrá Sana’a en 2030 no contarán con alimentos...

Estados Unidos está a punto de reformar su sistema de prestación de asistencia alimentaria en el extranjero, vigente desde hace medio siglo, que sus críticos consideran obsoleto, ineficiente y hasta perjudicial para las economías de los países en desarrollo. Expertos en desarrollo y encargados de...

Con su vestimenta tradicional naranja, Agaichetou Toure está tranquilamente sentada en la sala de espera de un centro para desplazados ubicado en Kalaban-Koura, un popular barrio en las afueras de la capital de Malí.  Toure tardó casi dos años en registrarse como desplazada, porque desconocía que...

Especialistas del Centro de Investigación y Asistencia en Tecnología y Diseño del Estado de Jalisco (CIATEJ) desarrollan un biosensor que determine, en tiempo real, cuándo la leche no es apta para el consumo humano, y se espera que su uso sea industrial. Fuente :...

En général, quand un verre tombe sur le plancher, il se brise. Pourtant, à l'avenir, le verre qui tombe devrait se courber et se déformer légèrement, grâce à une technique mise au point au Département de génie mécanique de l'Université McGill. En effet, le professeur François Barthelat et son...

Los ajustes en la política cambiaria de Argentina preocupan a Brasil y replantean la necesidad de una agenda “positiva” de integración, destinada a compensar desequilibrios comerciales, en caso de abruptos cambios macroeconómicos que afecten a uno u otro país.   La palabra “incertidumbre” se...

Researchers have shown that retrieval practice can improve memory in individuals with severe traumatic brain injury. Despite the small sample size, it was clear that retrieval practice was superior to other learning strategies in this group of memory-impaired individuals with severe traumatic brain...

Scientists investigated native aromatic xyrophytes for use in extensive green roofs in semiarid Mediterranean regions using locally produced grape marc compost as a substrate component. Aromatics Artemisia absinthium, Helichrysumitalicum, and H. orientale were found suitable for growth in extensive...

Researchers studied well-watered citrus to determine changes in water relations during cold acclimation, independent of drought stress. Potted sweet orange and Satsuma mandarin trees were exposed to progressively lower, non-freezing temperatures to promote cold acclimation. Results indicated that...

Can scientists generate any color of light? The answer is not really, but the invention of the laser in 1960 opened new doors for this endeavor. Scientists have now demonstrated a new semiconductor microstructure that performs frequency conversion. This design is a factor of 1000 smaller than...

In recognition of his seminal work on adenoviral vectors, which accelerated the translation of gene therapy from the research laboratory to the clinic, Ronald G. Crystal, MD (Weill Cornell Medical College, Cornell University, New York City), has received a Pioneer Award from Human Gene Therapy, a...
