An experimental drug aimed at restoring the immune system's ability to spot and attack cancer-halted cancer progression or shrank tumors in patients with advanced melanoma, according to a multi-site, early-phase clinical trial at Johns Hopkins Kimmel Cancer Center and 11 other institutions. All...

Chemotherapy can leave a long-lasting epigenetic imprint in the DNA of breast cancer patients' blood cells. That imprint is associated with biological signs of inflammation up to six months after the completion of treatment. Fuente : http://www.eurekalert.org/pub_releases/2014-03/ehs...

Johns Hopkins researchers say they have identified a set of genes that appear to predict which tumors can evade detection by the body's immune system, a step that may enable them to eventually target only the patients most likely to respond best to a new class of treatment. Fuente :...

Astronomers at the University of Washington have developed a new method of gauging the atmospheric pressure of exoplanets, or worlds beyond the solar system, by looking for a certain type of molecule. And if there is life out in space, scientists may one day use this same technique to detect its...

Researchers have discovered a link between prostate cancer aggressiveness and the accumulation of a compound produced when cholesterol is metabolized in cells, findings that could bring new diagnostic and treatment methods. Findings also suggest that a class of drugs previously developed to treat...

While there is no doubt that steps should be taken to lower the amount of overall food waste in schools, the new standards from the USDA appear to be a step in the right direction by helping students to consume more fruits and vegetables without leading to an increase in the amount of food thrown...

New federal standards launched in 2012 that require schools to offer healthier meals have led to increased fruit and vegetable consumption, according to a new study from Harvard School of Public Health. Fuente : http://www.eurekalert.org/pub_releases/2014-03/hso...

Researchers have come a step closer to understanding how gonorrhea infections are transmitted. When Neisseria gonorrhoeae, the bacteria responsible for gonorrhea, are exposed to seminal plasma, the liquid part of semen containing secretions from the male genital tract, they can more easily move and start to colonize. The...

Researchers have used a DNA barcoding technique in an attempt to clarify the number of species which existed of the extinct New Zealand moa. The challenges of understanding extinct fauna can be formidable and particularly so when it comes to this ancient bird. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/d...

Al encontrarse con un conocido después de mucho tiempo, un joven cachemiro exclama en una farmacia de Srinagar: “¡Estabas desaparecido!”. Su comentario suscita una respuesta inesperada en el otro: “Mide tus palabras. Hay personas cuyos seres queridos realmente desaparecen”. En el fronterizo estado indio de Jammu y Cachemira,...

Experts unveil their recommendations to improve health care for prisoners both during incarceration and after release. From a public health standpoint, they argue, it's shortsighted to regard prison populations as separate from the community. More than 95 percent of prisoners will return to the community, often carrying...

Studies examining the potential health benefits of moderate drinking generally focus on average levels of drinking rather than drinking patterns. A new study shows that, among older moderate drinkers, those who binge drink have a significantly greater mortality risk than regular moderate drinkers. The findings highlight the...

Many people believe that hangovers can either delay subsequent drinking due to pain and discomfort, or hasten drinking to relieve hangover symptoms. A new study investigates if a hangover that follows a drinking episode can influence the time to next drink. Results indicate that hangovers appear to have a very modest effect on...

Sexual aggression has become a common experience in bars. New findings show that approximately 90 percent of the incidents involve male initiators and female targets. The initiators' level of invasiveness was related to intoxication of the targets but not their own intoxication. This suggests that intoxicated women were being...

El filme documental “The Act of Killing” (El acto de matar), que retrata las masacres que se perpetraron en Indonesia en 1965 y 1966, perdió el premio Oscar para el que estaba postulado, pero quizás gane en otros terrenos. Al ver cómo antiguos mafiosos y jefes paramilitares actúan algunas escenas de esas masacres es fácil...

Elephants, rhinoceroses and aurochs once roamed around freely in the forests of Europe, while hippopotamuses lived in rivers such as the Thames and the Rhine. New research shows how we can use knowledge about the past to restore a varied landscape with a high level of biodiversity. Fuente :...

The enzyme PP1 has a key role in many of the body's healthy functions and diseases. It's so generally important that drug developers dare not target it. In a new study, scientists report a big leap in understanding how PP1 interacts with other proteins to behave specifically in distinct situations....

The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these chemicals overnight along the coast, a team of atmospheric chemists reports. Fuente :...

A comprehensive new study of global food supplies confirms and thoroughly documents for the first time what experts have long suspected: over the last five decades, human diets around the world have grown ever more similar -- by a global average of 36 percent -- and the trend shows no signs of...

When the sun sets on a remote desert outpost and solar panels shut down, what energy source will provide power through the night? A battery, perhaps, or an old diesel generator? Perhaps something strange and new. Scientists now envision a device that would harvest energy from Earth's infrared...

Los auditorios rectangulares ofrecen ventajas acústicas por la reflexión del sonido que se produce en sus paredes laterales y la mejor respuesta dinámica. Así lo recoge un estudio realizado por investigadores de la Universidad Aalto (Finlandia) en diez salas europeas. Fuente :...

¿Qué pasaría si un grupo de elefantes o rinocerontes salvajes campasen en la actualidad por el continente europeo? Esta es la propuesta de un grupo internacional de investigadores que ha estudiado la composición del paisaje del período interglacial anterior al actual –hace entre 132.000 a 110.000 años– en Europa.

Aalto University researchers have found that music is perceived to have greater dynamic range in rectangular, shoebox shaped concert halls than in other types of halls. From a shoebox hall’s sidewalls, strong reflected sound arrives to listeners’ ears from directions where human directional hearing...

A new approach to breast reconstruction surgery aimed at helping patients’ bodies get back to normal more quickly cut their postoperative opioid painkiller use in half and meant a day less in the hospital on average, a Mayo Clinic study found. The method includes new pain control techniques,...
