La cercana galaxia NGC1277 se formó en los albores del cosmos, cuando el universo tenía dos mil millones de años, y ha permanecido inalterada desde entonces, por lo que constituye una ventana única al universo primitivo. Así lo revela un estudio de astrónomos del Instituto de Astrofísica de...

Un estudio matemático de la Universidad Carlos III de Madrid (UC3M) basado en teoría de redes sugiere que reestructurar determinados préstamos interbancarios ayudaría a contener la propagación de crisis económicas en el sistema financiero. Fuente :...

El investigador Miguel A. Alonso Zarazaga, del Museo Nacional de Ciencias Naturales, ha descubierto un nuevo género de coleóptero en las islas Canarias, que ha denominado Moreiba. Estos escarabajos se incluyen dentro de la familia de los gorgojos, un grupo que causa numerosas plagas en los...

Quince días después de que se firmara un ingenioso acuerdo sobre el programa nuclear de Irán, el texto parece a salvo de ataques de envergadura del lobby israelí en el Congreso legislativo de Estados Unidos, al menos por ahora. Pese a que los legisladores del opositor Partido Republicano y un par...

L'efficacité de la majorité des antipsychotiques dépend de leur pharmacocinétique, c’est-à-dire de leur capacité à se retrouver dans la circulation sanguine après avoir été absorbés. C'est ce que nous apprennent Philippe Vincent et Édouard Kouassi, de l'Institut universitaire en santé mentale de...

The clinical context of the administration and dosage of antipsychotics may influence their efficacy, reported Philippe Vincent and Édouard Kouassi, from the Institut universitaire en santé mentale de Montréal and Université de Montréal.

The most tweeted peer-reviewed articles published between 2010 and 2012, and the trends associated with their social media success, have been identified by Stefanie Haustein at the University of Montreal’s School of Library and Information Science. Fuente :...

A new brief therapy eases symptoms of combat-related psychological trauma, a University of South Florida nursing study shows. The research suggests Accelerated Resolution Therapy may be an option for veterans who do not respond optimally to conventional therapies endorsed by the Department of...

Like tiny construction workers, cells sculpt embryonic tissues and organs in the 3-D space. This task is complicated and requires constant communication between cells to coordinate their actions and generate the forces that will shape their environment into complex tissue morphologies. Fuente :...

Blood clots play an unexpected role in protecting the body from the deadly effects of bacteria by absorbing bacterial toxins, researchers at UC Davis, have found. The discovery may shed light on the pathology of septic shock. Fuente : http://www.eurekalert.org/pub_releases/2013-12/uoc...

Researchers from Brown University have found evidence of diverse mineralogy in the moon's South Pole Aitken basin, a giant crater left by an impact 4 billion years ago. The findings could mean that some minerals dug up during that ancient impact remain intact within the basin. If that's true, then the basin could hold vital...

Drugs that enhance a process called oxidative stress were found to kill rhabdomyosarcoma tumor cells growing in the laboratory and possibly bolstered the effectiveness of chemotherapy against this aggressive tumor of muscle and other soft tissue. The findings are the latest from the St. Jude Children's Research...

Después de tres décadas de socialismo supuestamente planificado (1960-1990), a lo largo de las cuales lo que se “planificaba” por las estructuras de gobierno y Estado muchas veces se cumplía a medias, se perdía en el olvido por falta de control o de realismo, o en el mejor de los casos se ejecutaba...

Scientists have discovered a quick-cook recipe for copious volumes of hydrogen, a breakthrough suggesting a better way of producing the fuel that propels rockets and energizes battery-like fuel cells. It could eventually even help meet key world energy needs -- without carbon emissions contributing...

In our youth we are strong and healthy and then we weaken and die -- that's probably how most would describe what aging is all about. But, in nature, the phenomenon of aging shows an unexpected diversity of patterns and is altogether rather strange, conclude researchers. Fuente :...

The energy needed to change the magnetic orientation of a single atom -- which determines its magnetic stability and therefore its usefulness in a variety of future device applications -- can be modified by varying the atom's electrical coupling to nearby metals. Fuente :...

Hematology researchers have manipulated key biological events in adult blood cells to produce a form of hemoglobin normally absent after the newborn period. Because fetal hemoglobin is unaffected by the genetic defect in sickle cell disease, these cell culture findings may open the door to a new...
