Data reported by the Hearts Beat Back: The Heart of New Ulm Project reinforce the positive influence of lifestyle factors in mitigating risks that potentially increase the likelihood of heart disease and other health problems. Findings based on 1,059 residents of New Ulm, Minn., underscore the...

Propping open clogged heart arteries with a "disappearing stent" has worked well for three years in the first people implanted with the unique device, according to research presented at the American Heart Association's Scientific Sessions 2013. Fuente :...

Researchers at Berkeley Lab have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery's capacity. This is the longest...

If presented with looking at an image or reading a paragraph describing the same product, consumers often prefer the visual option. However, according to a new study in the Journal of Consumer Research, visual presentation can lead to information overload and result in less systematic consideration...

Around 20 percent of all humans are persistently colonized with Staphylococcus aureus bacteria, a leading cause of skin infections and one of the major sources of hospital-acquired infections, including the antibiotic-resistant strain MRSA. University of Chicago scientists have recently discovered...

Consumers are bombarded with advertising throughout the course of any given day, often to the point where they rarely devote any conscious attention to processing the brand information. According to a new study in the Journal of Consumer Research, this is not necessarily bad news for companies....

From gourmet cooking to assembling a flower bouquet, consumers thrive in a creative environment. A new study in the Journal of Consumer Research suggests a greater sense of appreciation and overall value is given to products that are customized during the design process. Fuente :...

Although somewhat counterintuitive, it turns out that those who support a cause anonymously tend to be more meaningfully supportive of the cause than those who offer more noticeable initial support, according to a new study in the Journal of Consumer Research. Fuente :...

Consumers love a sale. In fact, when asked what makes a sale appealing, most simply say, "The price was good." But this answer fails to acknowledge that subjective factors also contribute to the perceived value of a deal. According to new research published in the Journal of Consumer Research, it's...

El colapso económico que vivió Islandia en 2008 se distingue de los de otros países porque afectó más la salud física y mental de las mujeres que la de los hombres, demuestran nuevos estudios. Las desempleadas, las estudiantes y las que no participan en el mercado de trabajo exhibieron niveles...

Las emisiones globales de dióxido de carbono por la quema de combustibles fósiles aumentarán de nuevo en 2013, alcanzando la cifra récord de 36 mil millones de toneladas. Así lo recogen los últimos datos del Global Carbon Project, codirigido desde el Centro Tyndall para la Investigación del Cambio...

La ONU tiene una larga tradición de conmemorar hitos políticos, como la abolición de la esclavitud, y de organizar interminables sesiones sobre temas polémicos, como los ensayos nucleares. La agenda del foro mundial cubre una amplia gama de tópicos políticos, sociales y económicos, con jornadas...

Therapeutic hypothermia – cooling the body and brain down to 33°C – is the method used worldwide to treat cardiac arrest, even though a lower body temperature may raise the risk of side-effects. However, keeping the temperature steady at 36°C is just as effective, a study led by Lund University...

Researchers have developed a simple scaling theory to estimate gas production from hydraulically fractured wells in the Barnett Shale. The method is intended to help the energy industry accurately identify low- and high-producing horizontal wells, as well as accurately predict how long it will take...

Researchers find that electrons teetering on the edge of free motion or stuck in place yield optimal superconductivity. Their work explains common characteristics between two different superconducting iron compounds and may help in the search for better "high-temperature" superconductors. Fuente :...

Why are men's noses bigger than women's? The answer, according to a new study lies in our physiology. Men's noses are about 10 percent larger than female noses, on average, because males have more lean muscle mass, which requires more oxygen for muscle tissue growth and maintenance. It also...

Researchers have redesigned the component materials of the battery in an environmentally friendly way to solve some of the problems associated with electric car batteries. By creating nanoparticles with a controlled shape, they believe smaller, more powerful and energy efficient batteries can be...

From a bacteria’s perspective the environment is one big DNA waste yard. Researchers have now shown that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with...

El chileno Hugo Hurtado, de 47 años, es chef. Cualquiera diría que en su país, el tigre de América Latina, esa profesión es un seguro de éxito y hasta de fama. Pero no para todos. Hurtado trabaja como camarero. “Estudié una profesión demasiado elitista ya que, sin contactos ni un restaurante...

Biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young. They attract more females by making more urinary pheromones, but smelling sexier shortens their lives. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/j...

Understanding superconductivity -- whereby certain materials can conduct electricity without any loss of energy -- has proved to be one of the most persistent problems in modern physics. Now scientists have teased out another important tangle from this giant ball of string, bringing us a...

Las personas que padecen hipertimesia, un síndrome que causa una memoria autobiográfica muy superior a la normal, también se pueden ver afectadas por recuerdos falsos. Estas mentiras se originan en el cerebro por la asociación de objetos, la valoración personal de eventos pasados o por la propia...

Men with prostate cancer who ate a low-fat diet and took fish oil supplements had lower levels of pro-inflammatory substances in their blood and a lower cell cycle progression score, a measure used to predict cancer recurrence, than men who ate a typical Western diet, researchers found.
