Black holes shape the growth and death of the stars around them through their powerful gravitational pull and explosive ejections of energy. In a recent Science paper, researchers predicted the formation of accretion disks and relativistic jets that warp and bend more than previously thought,...
Obesity, diabetes and other ailments plague impoverished communities at higher rates than the general United States population. In rural Texas border towns, or colonias, Mexican-American residents are at an even greater risk for chronic health problems. Fuente :...

Nobody can foresee disaster, but changing climate conditions are prompting smart communities increasingly to prepare for them with solid emergency response plans and protocols. Images as recent as those from the 2011 wildfire in Slave Lake, Alberta or as distant as those from the 1998 ice storm in...
Preliminary research findings from the UA suggest learning to use Facebook may help give adults older than 65 a cognitive boost. The study, conducted by UA graduate student Jannelle Wohltmann, shows that seniors who learned to use Facebook saw improvements in their ability to continuously monitor...
Solar geoengineering is a proposed approach to reduce the effects of climate change due to greenhouse gasses by deflecting some of the sun's incoming radiation. This type of proposed solution carries with it a number of uncertainties, however, including geopolitical questions about who would be in...
Researchers at Brown University have developed a robotic bat wing that is providing valuable new information about dynamics of flapping flight in real bats. From an engineering perspective, the researchers hope the data may make for better aircraft, especially micro air vehicles. From a biological...
Researchers from North Carolina State University have developed a way to melt or "weld" specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient...
Scientists have found compelling evidence that older adults can eliminate forgetfulness and perform as well as younger adults on memory tests. The cognitive boost comes from a surprising source -- a distraction learning strategy! Fuente : http://www.eurekalert.org/pub_releases/2013-02/bcf...
Although immigration to the United States from Latin-American countries, particularly Mexico, has captured much public attention, immigrants also move between countries in Latin America have more difficulty economically than those moving to the United States. Fuente :...
Pre-war vulnerability is just as important as combat-related trauma in predicting whether veterans' symptoms of post-traumatic stress disorder will be long-lasting, according to new research published in Clinical Psychological Science, a journal of the Association for Psychological Science.

Sourdough bread resists mold, unlike conventionally leavened bread. Now Michael Gaenzle and colleagues of the University of Alberta, Edmonton, show why. During sourdough production, bacteria convert the linoleic acid in bread flour to a compound that has powerful antifungal activity. The research, which could improve the...
Simon Fraser University virologist Masahiro Niikura and his doctoral student Nicole Bance are among an international group of scientists that has discovered a new class of molecular compounds capable of killing the influenza virus. Working on the premise that too much of a good thing can be a...
