Prostate cancer is the most common form of cancer in men, yet research has been stymied by imperfect animal models of the disease. Now, CSHL scientists have developed a new method to rapidly create much better mouse models for the most lethal, terminal events of metastatic prostate cancer. This discovery allows scientists to...

Researchers from the University of Hawaii, Lawrence Livermore National Laboratory, Lawrence Berkeley National Laboratory, and University of California discovered that interplanetary dust particles could deliver water and organics to the Earth and other terrestrial planets. "It is a thrilling...

In the beginning there were single cells. Today, many millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being. Despite the various ways these organisms achieved multicellularity, their conglomeration of cells operate cooperatively to consume...

Despertar el interés científico en la población infantil de zonas urbanas y rurales mediante actividades divertidas y juegos motivó a la asociación civil Planetarium Torreón, en Coahuila, a crear un planetario móvil, proyecto que contó con el patrocinio del Consejo Nacional de Ciencia y Tecnología...

Más de 1.100 refugiados sirios se beneficiaron desde septiembre del programa de Suiza para  la reunificación familiar, mientras miles esperaban una oportunidad similar en embajadas del país europeo en la región. Pero el plan llegó a su fin. Varias naciones europeas respondieron a una solicitud del...

Un equipo científico internacional ha logrado secuenciar el genoma de cáncer más antiguo descifrado hasta ahora, que ha sobrevivido 11.000 años. Se trata de un cáncer venéreo transmisible en cánidos que causa tumores genitales y que continúa propagándose entre perros domésticos hasta hoy. ...

La mayoría de los animales tienen en sus ojos entre dos y cuatro fotorreceptores para distinguir los colores. Los estomatópodos (Stomatopoda) o gambas mantis son los únicos seres vivos que tienen doce. Un equipo de investigadores ha resuelto parte del misterio de su peculiar sistema de visión: no...

Las muestras encontradas por el rover Opportunity en Marte indican que la acidez del agua que hubo en el planeta rojo en el cráter marciano Endeavour varió tras el impacto del meteorito que lo formó. Este robot, que ya lleva diez años en la superficie de Marte, y los hallazgos del Curiosity...

Maya Mexican oil type has up to 30 parts per million of sulfur, labeling it as heavy oil, meaning, too pollutant for the environment when used as raw material for fuels. Looking to reduce the national hydrocarbon emissions, a team of scientists from the Center of Nanosciences and Nanotechnology...

Ante el desafío de la era digital, las escuelas deben ir a un modelo alternativo al actual, con un profesorado que incorpore las nuevas tecnologías a su labor y encare una pedagogía más crítica, se planteó en el Foro Mundial de la Educación, desarrollado en esta ciudad del sur de Brasil. La...

In a pioneering project funded by the Mellon Foundation, scholars at Ludwig-Maximilians-Universitaet (LMU) in Munich are compiling a database of Arabic documents, many dating from the early years of Islam. The online resource affords unique insights into everyday life in Arab lands Fuente :...

La designación en República Centroafricana de Catherine Samba-Panza como presidenta de transición genera esperanzas en muchos de que pueda sofocar los conflictos étnicos. Pero analistas tienen sus dudas. Samba-Panza fue nombrada el lunes 20, en medio de episodios de violencia entre los rebeldes...

Scientists from the Florida campus of The Scripps Research Institute have identified a critical regulator of a molecule deeply involved in the progression of Alzheimer’s disease. The new study shows for the first time that levels of this regulating protein are decreased in the brains of Alzheimer’s...

When capturing images at the atomic scale, even tiny movements of the sample can result in skewed or distorted images -- and those movements are virtually impossible to prevent. Now microscopy researchers have developed a new technique that accounts for that movement and eliminates the distortion...

Researchers have deciphered the structure of part of the ribosome found in mitochondria, the power plants of the cell. The scientists were able to benefit from advancements in the field of electron microscopy and capture images of the mitochondrial ribosome at a level of resolution never achieved...

The Wnt/²-catenin signaling pathway and microRNA 335 are instrumental in helping form differentiated progenitor cells from stem cells. These are organized in germ layers and are thus the origin of different tissue types, including the pancreas and its insulin-producing beta cells. With these...

A new long-range wireless tag detection system, with potential applications in health care, environmental protection and goods tracking, can pinpoint items with near 100 percent accuracy over a much wider range than current systems. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/0...

Researchers have identified a biological mechanism that could explain how the Earth’s atmospheric carbon dioxide and climate were stabilized over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing down...

One of the first research studies empirically tests potential reasons why firm leaders and non-leaders -- or professional staff -- can have contrasting perspectives of the firm's ethical environment. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/s...

Stem cells can turn into heart cells, skin cells can mutate to cancer cells; even cells of the same tissue type exhibit small heterogeneities. Scientists use single-cell analyses to investigate these heterogeneities. But the method is still laborious and considerable inaccuracies conceal smaller effects. Scientists have now...

In common perception, carbon dioxide is just a greenhouse gas, one of the major environmental problems of mankind. For Warsaw chemists CO2 became, however, something else: a key element of reactions allowing for creation of nanomaterials with unprecedented properties. Fuente :...

El observatorio espacial Herschel de la ESA ha descubierto vapor de agua en el entorno de Ceres. El hallazgo confirma que este planeta enano tiene una superficie helada y una atmósfera. Además, se trata de la primera detección inequívoca de vapor de agua en un objeto del cinturón de asteroides....
